Answer:
y - 4 = -8/7(x - 4)
Step-by-step explanation:
Point-Slope form: y - y₁ = m(x - x₁)
x₁ and y₁ would be the coordinates of the point (4,4).
m would be the slope -8/7.
Substituting these values:
y - 4 = -8/7(x - 4)
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - [tex]\frac{8}{7}[/tex] and (a, b) = (4, 4) , then
y - 4 = - [tex]\frac{8}{7}[/tex] (x - 4) → B

If ∠A and ∠B are supplementary angles, m∠A = (11x 26−) , a°nd m∠B = (− 4x+ 87)° then what is the value of x?
x = __________
Answer:
x =17
Step-by-step explanation:
(11x -26) + (− 4x+ 87) =180

7x = 119
x =17
You have $50 in your bank account. Each week you plan to deposit $6 from your allowance and $20 from your paycheck. The equation b = 60 + (20+6)w gives the amount b in your account after w weeks. How many weeks from now will you have $215 in your bank account?
6 weeks from now, you will have $215 in your bank account
How many weeks from now will you have $215 in your bank account?The given parameters are:
b = 60 + (20+6)w
When the account balance is $215, we have
60 + (20+6)w = 215
Subtract 60 from both sides
(20+6)w = 155
This gives
26w = 155
Divide both sides by 26
w = 5.96
Approximate
w = 6
Hence, 6 weeks from now, you will have $215 in your bank account

what is the rate of chnage
A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 3200 seats. The students filled 2112 of the seats in the theater. What percentage of the seats in the theater were filled by the 6th graders on the trip?
The 6th graders filled 66% of the seats in the theater on the field trip.
To find the percentage of seats in the theater that were filled by the 6th graders on the field trip, we can use the following formula:
Percentage = (Filled Seats / Total Seats) * 100
Filled Seats = 2112
Total Seats = 3200
Substituting the values into the formula:
Percentage = (2112 / 3200) * 100
Percentage = 0.66 * 100
Percentage = 66%

The 6th-grade students filled approximately 66 percent of the 3200 seats in the theater during their field trip to see the ballet.
Use the concept of percentage defined as:
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Given that,
A middle school took its 6th-grade students on a field trip to see a ballet.
The field trip took place at a theater.
The theater has a total of 3200 seats.
The 6th-grade students filled 2112 of the seats in the theater.
To calculate the percentage of seats filled by the 6th-grade students:
Use the formula = (Number of seats filled / Total number of seats) x 100.
In this case,
The number of seats filled by the 6th-grade students is 2112, and the total number of seats in the theater is 3200.
Put the values, we get,
(2112 / 3200) x 100 = 66%
Hence
The 6th graders filled approximately 66% of the seats in the theater.

A right triangle has one leg with a length of 18 mm and a hypotenuse with a length of 82 mm.
What is the length of the other leg?
Your answer
Answer:
80 mm
Step-by-step explanation:
Pythagorean theorm can be applied here to solve for the length of the last leg, [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex], where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following:
b = √c^2 - √a^2
= √(82)^2 - √(18)^2
= √6724 - √324
= √6400
= 80 mm

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal cost $78.90 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the cost of the meal?
Answer:
The 15% discount means that they only pay 100%-15% = 85% of the meal's bill.
This would cost 85% * 78.65.
However, they also have to pay a 20% tip of the meal cost.
This would cost 20% * 78.65.
Step-by-step explanation:
total Cost = (85% * 78.65) + (20% * 78.65)
= 105% * 78.65
= 1.05 * 78.65
= $82.58

Answer:
∠6=116°
Step-by-step explanation:
Buckle up :)
We are given the values of ∠4 [tex](-2x+94)[/tex] and ∠8 [tex](-5x+139)[/tex].Vertical angles are congruent. Angle 4 and angle 1 are vertical angles, so angle 1 is also [tex]-2x+94[/tex].∠1 and ∠8 are alternate exterior angles. The transversal is the line that crosses over the parallel lines. When two angles are on opposite sides of the transversal, they are alternate angles. When the two angles are on the outside of the parallel lines, they are exterior angles. This makes them alternate-exterior angles.Alternate exterior angles are congruent. This means that ∠1≅∠8. Write an equation in order to solve for x:[tex]-2x+94=-5x+139[/tex]
Solve for x. Subtract 94 from both sides:
[tex]-2x+94-94=-5x+139-94\\\\-2x=-5x+45[/tex]
Add 5x to both sides:
[tex]-2x+5x=-5x+5x+45\\\\3x=45[/tex]
Divide both sides by 3:
[tex]\frac{3x}{3} =\frac{45}{3} \\\\x=15[/tex]
Insert the value of x into angle 4 because they are same-side interior angles. This is because they are on the same side of the transversal and within the parallel lines. Same-side interior angles are supplementary, so their value will add up to 180°. Therefore, in order to find angle 6, we need to first find the true value of angle 4:
[tex]x=15\\\\-2(15)+94\\\\-30+94\\\\64[/tex]
∠4 is 64°. Use ∠a+∠b=180 to find angle 6:
[tex]a+64=180[/tex]
a represents angle 6. Subtract 64 from both sides:
[tex]a+64-64=180-64\\\\a=116[/tex]
Angle 6 has a measure of 116°.

Solve for F
Solving for the variable 'f' gives f = 100 - 2h/5
What is subject of formula?A subject of formula can be defined as the variable that is expressed in terms of other variables in a given expression, function of equation.
It is the variable that is worked out in an equation and left to stand on its own on one side of the equality sign
Given the equation;
5f+2h = 100
To make 'f' the subject of formula, we take the following steps;
Take '2' over the equality sign
5f = 100 - 2h
Now, let's make 'f' the subject by dividing both sides by its coefficient which is 5
We have;
5f/5 = 100 - 2h/5
Divide through
f = 100 - 2h/5
Thus, solving for the variable 'f' gives f = 100 - 2h/5

Performing LCM, the least number of pencils and pens that she needs to buy are 60 pencils and 60 pens.
LCM refers to the least common multiple. The LCM of two or more numbers is the one that can divide all the numbers by the single number itself.
Pencils come in packages of 20 and pens come in packages of 12.
So, the possible lowest common multiplier is LCM of 20 and 12, and it is 60.
So she has to buy 3 packages of pencils (60/20 = 3 ) as well 5 packages of pens ( 60/12 = 5 ).

Leslie surveyed 80 students in her grade and found that 47 students had a dog of those students, 17 of them also had a cat. There were 24 students that had a cat, but not a dog. There were 9 students that did not have a cat or a dog. Move values to create a two-way table that shows the data from Leslie's survey.
A two–way table that shows data from Leslie's survey is presented as follows;
Dog. No dog Total
Cat. 17. 24. 41
No cat. 30. 9. 39
Total 47. 33. 80
How can the two–way table be completed?The given parameters are;
Number of students in the survey = 80Number that had a dog = 47Number that also had a cat = 17Number that have cats but no dogs = 24Number that have neither cats or dogs = 9Solution;
The number that have dogs and no cat = 47 - 17 = 30
Therefore, we have;
Dog and cat = 17
No dog and cat = 24
No dog no cat = 9
Total number that have cats = 17 + 24 = 41
Number that have no cats = 30 + 9 = 39
Sum total of students that have no dogs = 24 + 9 = 33

Help me find the X! UwU..
Well all the angles in a triangle add up too 180º and this triangle is obviously a equilateral triangle (all sides are same) BUT as you see the other people saying X = 60º notice that it says 2 xº meaning that it is X x 2 so 60º is actually wrong :).
If it is X is 60º (since the 3 angles add together since it’s equilateral) then that would be 2 x 60º = 120º times 3 WHICH IS NOT 180.I think U get what I mean now,it’s 2 Xº; so X is 30 because 30 x 2 = 60º and 60 x 3 = 180º!
So Da Answer is X = 30º
Hope this helped :)

Answer: 120.
Step-by-step explanation: the angles of a triangle add up to 180 degrees. angles c and d are given and their values add up to 120 degrees. so E must be 180-120, which equals 60 degrees. We also know that a straight line is 180 degrees and since one side is 60 degrees, the other one must add up with 60 to give 180, which is 120.
