Answer:
Is there a picture for this one and also you didn't mention the slope of the red line is?
Step-by-step explanation:
Answer:
The slope of the Green line should be the same as the red line- but a negative number instead of a positive.
Step-by-step explanation:
This is the inverse of the line
So by reflecting it over the y-axis, the slope remains the same but will change from positive to negative and vise versa
From 13 friends to 14 friends
Percent increase
ANSWER :
about a 1.076% increase
EXPLANATION :
1. Set up your equation
13/100 = 14/x
2. Cross multiply
13x = 1400
3. Divide by thirteen on both sides
x = 107.692307
4. Transform it into percent [ divide by a hundred ]

Isaiah is working two summer jobs, making $16 per hour tutoring and $10 per hour clearing tables. Isaiah must earn at least $110 this week. Write an inequality that would represent the possible values for the number of hours tutoring, tt, and the number of hours clearing tables, cc, that Isaiah can work in a given week.
Answer:
16t + 10c > 110
Step-by-step explanation:
Cost of tutoring per hour = $16
So, cost of tutoring t hours = $16t
Cost of clearing tables per hour = $10
So, cost of clearing tables c hours = $10c
Since, Isaiah must earn at least $110 this week.
Therefore, the required inequality will be given as:
16t + 10c > 110

Determine the measure of the angle in ?
Answer:
? = 30°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
48° is an exterior angle of the triangle, then
? + 18° = 48° ( subtract 18° from both sides )
? = 30°

Sushi was thinking of a number. Sushi doubles it,then adds 20 to get an answer of 27.7 what was the original number
Answer:
3.85
Step-by-step explanation
7.7 divided by 2 = 3.85
So if you double 3.85 you get 7.7 and then add 20 to 7.7 then you get 27.7
Let the number they are thinking of be X.
They double x , which would be 2x.
They then add 20, which would be 2x +20
So you have 2x + 20 = 27.7
Now we can solve for x:
Subtract 20 from both sides:
2x = 7.7
Divide both sides by 2:
x = 7.7 / 2
x = 3.85
The original number was 3.85

Answer:
What is the value of x?
x = 40 degrees.
What is the measure of angle AFE?
Angle AFE = 140 degrees
What is the measure of angle BFD?
Angle BFD = 140 degrees.
Step-by-step explanation:
Angle AFC is 90 degrees.
To find angle x, we have to subtract angle BFC.
90 - 50 = 40 degrees.
Line BFE is 180 degrees.
To find angle AFE, we have to subtract angle x from 180 degrees.
We have solved x already.
180 - 40 = 140 degrees.
Angle BFD is just 90 degrees plus 50 degrees.
90 + 50 = 140 degrees.
Answer:
x = 40
m<AFE = 140
m<BFD = 140
Step-by-step explanation:
1. Finding X
As one can see, AD is a straight line (hence the three angles that add up to is equal 180 degrees). It is given that m<CFD is 90 degrees (signified by the box).
Given;
AD - straight line
m<AFB + m<BFC + m<CFD = 180
( m<AFB, m<BFC, m<CFD form line AD, the degree measures in al ine equal 180, hence m<AFB + m<BFC + m<CFD = 180)
m<BFC = 50
m<CFD = 90 (signified by box around it)
m<AFB + m<BFC + m<CFD = 180 parts whole postulate
x + 50 + 90 = 180 substitution
x + 140 = 180 algebra
x = 40
2. Finding m<AFE and m<BFD
When two straight lines intersect, four angles are formed. The angles that are opposite to each other are called vertical angles, and vertical angles are congruent in other words, have the same measure.
Given;
m<BFD = m< AFE
m<BFC + m<CFD = m<BFD
m<BFC = 50
m<CFD = 90
m<BFC + m<CFD = m<BFD Given (parts whole postulate)
50 + 90 = m<BFD substitution
140 = m<BFD algebra
140 = m<BFD = m<AFE substition

9(x - 2) = 7x + 5 a) true for all values of x b) true for one value of x c) true for no values of x
Answer:
b) true for one value
Explanation:
If you solve for x, there is only one value of x
Answer:
(b)
Step-by-step explanation:
9(x - 2) = 7x + 5 ← distribute left side
9x - 18 = 7x + 5 ( subtract 7x from both sides )
2x - 18 = 5 ( add 18 to both sides )
2x = 23 ( divide both sides by 2 )
x = [tex]\frac{23}{2}[/tex]
What’s the answer????
my teacher didn't teach me anything about scale factors and then assigned it to me- pls show work so that I can understand this hhhhhhhh
Answer:
x = 9 cm
y = 30 cm
Step-by-step explanation:
Here, we want to get the lengths of the missing sides
Mathematically if two shapes are similar, the ratio of their corresponding sides are equal
Thus, we have that:
15/50 = x/30
50 * x = 15 * 30
x = (15 * 30)/50
x = 450/50
x = 9 cm
Also;
y/50 = 18/30
30 * y = 50 * 18
y = (50 * 18)/30
y = 30 cm

A number is first decreased by 40% and then again decreased by 60%. Find the percentage increase or decrease in the whole sum...please tell quickly
Answer:
It is decreased by 76 percent.
Step-by-step explanation:
The key skills are percentage and multiplication with percentages.
You first have to get a variable. Let's use the letter o as a variable (o For orginial cost). Then we have to find out how much it is when o is decreased by 40 percent. 100% (or the whole) - 40% is 60%. Therefore, with a 40 percent decrease, It would be 60% of o, or 0.6o. Then, if it decreases by 60 percent, the final number would be 100% - 60 % or 40% of 0.6o. This means itbwould be 0.4 × 0.6o which is 0.24o0.24o means that o is 24 percent of its orginial number, which is 100% - 24% or a 76 percent decrease.Hope you understood and have a nice day!
