Answer:
y = 3/2 x + 9/2
Step-by-step explanation:
3x - 2y = 5
3x - 5 = 2y
3/2 x - 5/2 = y
y = 3/2 x - 5/2, slope of this line m = 3/2.
For parallel line slope is the same.
y = mx + b
y = 3/2 x + b
Using point (-1,3) , we can find b.
3 = (3/2)*(-1) + b
3 = -3/2 + b
b = 3 + 3/2 = 6/2 + 3/2 = 9/2
y = 3/2 x + 9/2
Solve the equation.

A box contains 56 balls. The probability of selecting a red ball at random is 5/7. How many balls in the box are not red?
Answer:
Brain to me plz
Step-by-step explanation:
2/7 is the balls are not red, so 2/7 multiplyed by 56
which is 16
Answer:
16 balls
Step-by-step explanation:
If 5/7 of the balls are red then the fraction of balls that are not red is;
[tex]\frac{7}{7} - \frac{5}{7} = \frac{2}{7}[/tex]
Which means 2/7 of the balls are not red. So to get the number;
[tex]= \frac{2}{7} * 56 \\= 2 * 8\\[/tex]
= 16
∴16 balls are not red

Answer:
C) 38
Step-by-step explanation:
You are solving for m∠QSR.
Given:
m∠TSR (Total of the two angles) = 70
m∠QST = 2x
m∠QSR = 3x - 10
Set the two angles equal to the total measurement of angles:
2x + 3x - 10 = 70
Simplify. Combine like terms. Add 2x & 3x:
2x + 3x = 5x
5x - 10 = 70
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 to both sides:
5x - 10 = 70
5x - 10 (+10) = 70 (+10)
5x = 70 + 10
5x = 80
Next, divide 5 from both sides:
(5x)/5 = (80)/5
x = 80/5
x = 16
Then, plug in 16 for x in the expression given. Remember you are solving for m∠QSR.
m∠QSR = 3x - 10
m∠QSR = 3(16) - 10
m∠QSR = 48 - 10
m∠QSR = 38
C) 38 is your answer.
~
Answer:
38
Step-by-step explanation:
the sum of two angles =70
2x+3x-10= 70
5x=80
x=80/5=16
QSR= 3x-10=3*16 -10= 48-10= 38
What are the measures of interior angle a and exterior angle b?
a=____
b=____
*20 points*
Answer:
a = 180 - 92 - 27=61
b = 92 + 27= 119
Step-by-step explanation:
Answer:
Interior Angle A = 180 - (27 +92)
= 180 - (119)
= 61 degrees
Exterior Angle B = 180 - 61
= 119 degrees
Which of the following expressions represents the area, in square meters, of the regular decagon (10-sided polygon) with 3.25 meter-sides and a 5-meter apothem.
Answer:
A = P * a / 2
A = 81.25
Step-by-step explanation:
We have that there is a corresponding formula for a regular decagon, which depends on the apothem and the perimeter, it is the following:
A = P * a / 2
In this case, the perimeter is the sum of all the sides, that is, 10 sides, therefore:
P = 10 * 3.25
P = 32.5 meters
We replace:
A = 32.5 * 5/2
A = 81.25
Which means that for that regular decagon, the area is 81.25 square meters.

how do you figure out what is a trinomial?
Answer:
To factor trinomals in the form of x^2+bx+c, you have to find 2 integers, r and s, whose product is c, and whose sum is b. You have to rewrite the trinomial as x^2+rx+sx+c and then using the grouping and distribution of property to factor the polynomial. The result of the factors will be (x+r) and (x+s)

How to get this answer:
Locate 6 on the x axis. Draw an arrow down until you reach the f(x) curve, then move to the left until you reach the y axis. We started at x = 6 and ended on y = -6. See the diagram below for this process in action.
So basically f(6) = -6. Visually the point (6,-6) is on the f(x) curve.
Through similar steps, we see that g(5) = -5
Therefore,
4*f(6) - 6*g(5) = 4*(-6) - 6*(-5) = -24 + 30 = 6

Solve 7y-6=2y+8
Show that 7/8-5/6=1/24
Show that 5/8÷7/12=1 1/14
Simplify fully v4×v7÷vt
Answer:
Please check the explanation part for more details.
Step-by-step explanation:
1. Solve [tex]7y - 6= 2y + 8[/tex]
Send all components contain [tex]y[/tex] to the left, the other components to the right:
<=> [tex]7y - 6 = 2y + 8[/tex]
(sign of [tex]2y[/tex] is changed from negative to positive, sign of [tex]6[/tex] is changed from negative to positive)
<=> [tex]5y = 14[/tex]
Divide both sides of equation by [tex]5[/tex]:
<=> [tex]y = \frac{14}{5}[/tex]
2. Show that [tex]\frac{7}{8} - \frac{5}{6} =\frac{1}{24}[/tex]
First, we prove that [tex]24[/tex] is least common multiple(LCM) of the denominators of [tex]2[/tex] components on the left side ([tex]8[/tex] and [tex]6[/tex]).
[tex]8 = 2^{3}[/tex]
6 = [tex]2[/tex] x [tex]3[/tex]
=> LCM = [tex]2^{3}[/tex] x [tex]3[/tex] = [tex]8[/tex] x [tex]3[/tex] = [tex]24[/tex]
Multiply the first component [tex]\frac{7}{8}[/tex] by a factor which is equal to the quotient of LCM and denominator: [tex]\frac{24}{8} = 3[/tex]
=> [tex]\frac{7}{8} = \frac{7*3}{8*3} = \frac{21}{24}[/tex]
Multiply the second component [tex]\frac{5}{6}[/tex] by a factor which is equal to the quotient of LCM and denominator: [tex]\frac{24}{6} = 4[/tex]
=>[tex]\frac{5}{6} = \frac{5*4}{6*4} = \frac{20}{24}[/tex]
=>[tex]\frac{7}{8} -\frac{5}{6} = \frac{21}{24} - \frac{20}{24} = \frac{1}{24}[/tex]
3. Show that [tex]\frac{5}{8} / \frac{7}{12} = \frac{11}{14}[/tex]
[tex]\frac{5}{8} / \frac{7}{12} =[/tex] [tex]\frac{5}{8} * \frac{12}{7} =[/tex] [tex]\frac{60}{56} =\frac{60/4}{56/4} = \frac{15}{14} = 1\frac{1}{14}[/tex]
4. [tex]\frac{v4*v7}{vt} = \frac{v}{v} * \frac{v*4*7}{t} = \frac{v*28}{t}[/tex]

The cost of a hall rental for a wedding is $500. Each meal at the wedding will cost an additional $45.50
a) Write an algebraic expression equation for the total cost of the wedding.
b) Calculate how many people attended the wedding if the wedding cost totalled $3912.50.
Answer:
a) 45.50p + 500
b) 45.50p + 500 = 3912.50
p = 70
Step-by-step explanation:
p = number of people
$45.50 for a meal for each person, so:
45.50p
The constant is $500, so let's add that to the expression:
45.50p + 500
Karen is making a set of costumes for the school play using a piece of cloth. She reduces the length of the cloth she intends to use by 10%. If the initial length of the cloth that she wanted to use was 15 meters, what is the new length of the cloth she wants to use?
Answer:
The new length is 13.5 meters
Step-by-step explanation:
Here, we are interested in calculating the new length of the cloth she wants to use
What we know from the question is that she is making a reduction of 10% from an initial of 15 meters
Thus, the length she is to use can be calculated by first getting what 10% of 15 meters is
Mathematically, that would be ;
10/100 * 15 = 1.5 meters
We now subtract this from the total of 15 meters
= 15 meters - 1.5 meters = 13.5 meters
