Consider the two graphs above.
Which statement best describes the graphs?
A. Graph 1 represents a proportional relationship, but graph 2 does not.
B. Graph 2 represents a proportional relationship, but graph 1 does not.
C. Both graph 1 and graph 2 represent proportional relationships.
D. Neither graph 1 nor graph 2 represent a proportional relationship.
Answer:
B. Graph 2 represents a proportional relationship, but graph 1 does not.
Step-by-step explanation:
All proportional relationships pass through the origin. Graph 2 does but Graph 1 does not. Additionaly, Graph 2 is a straight line that represents a proportional relationship. Another way to find out if it is proportional is to find the constant of proportionality by dividing the y by the x in different parts of the line. The numbers should all have the same constant of proportionality.
Examples (all found in Graph 2):
15/3 = 5
10/2 = 5

Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form. (-6,6), (6,2)
Point-Slope form = y-y1=m(x-x1)
Y-6 = -1/3 (x+6)
Slope-intercept form = Y=mx+b
y = -1/3 + 4
The equation of line is y= -2/3x + 2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
Points: (-6,6), (6,2)
Slope= (-2 - 6)/( 6 -(-6))
slope= -8 / 12
slope= -2/3
Now, using slope intercept form
y-b = m(x- a)
y- 6 = -2/3( x + 6)
y -6 = -2/3x - 4
y= -2/3x + 2
Hence, the equation of line is y= -2/3x + 2.

State the equation that results when both sides of 2x - 3y = -4 are multiplied by -3.
Answer:
6x - 9y = -12
Step-by-step explanation:
2x - 3y = -4 multiply both sides by 3 by adding paranthesis to represent this
3( 2x - 3y ) = 3 (-4) Then use distributive property for the left side equation
6x - 9y = -12 Finally just multiply -4 by 3 and you get this equation

The directions on a sewing pattern say to buy an extra 12.5% of fabric to account for error. Sam needs 2.75 yards of fabric to make a shirt, so he buys 2.4 yards. Choose the correct statement.
A.Sam bought the correct amount of fabric because he bought what was suggested.
B.Sam bought the correct amount of fabric because he needs less than 2.4 yards.
C.Sam did not buy the correct amount of fabric because he needs less than 2.4 yards.
D.Sam did not buy the correct amount of fabric because he should have bought 3.09 yards
Answer:
Sam should have bought 3.09 yards of fabric instead of 2.4 yards
So, Option D is correct.
Step-by-step explanation:
Total fabric needed by Sam = 2.75
According to directions on a sewing pattern they say to buy an extra 12.5%
So, extra fabric would be: 12.5% of 2.75
Solving
[tex]12.5\% \ of \ 2.75\\=\frac{12.5}{100}\times 2.75 \\=0.343[/tex]
Now adding 0.343 into 2.75 to get extra fabric quantity:
2.75+0.343
=3.09
Therefore Sam should have bought 3.09 yards of fabric instead of 2.4 yards
So, Option D is correct.
A bowl of fruit contains a 4: 1 ratio of blueberries to strawberries. There is a total of 65 berries in the bowl. How many of them are blueberries and how many are strawberries?
9514 1404 393
Answer:
52 blueberries13 strawberriesStep-by-step explanation:
There are a total of 4+1 = 5 ratio units, so each one stands for 65/5 = 13 berries.
blueberries : strawberries = 4 : 1 = 52 : 13
There are 52 blueberries and 13 strawberries in the bowl.

Chick-fil-A offers its customers a choice of regular and diet soda. Last night, Chick-fil-A served 50 sodas in all, 27 of which were regular. What percentage of the sodas were regular?
Answer:
54%
Step-by-step explanation:
We know Chick-fil-A served 50 sodas in all, 27 of which were regular. The fractional form of this is 27/50. Now, we can convert this to a fraction with a denominator with 100, then a percentage. 27/50 is equal to 54/100.
54/100 is 54%
Answer:
is 54.the max is 100 percent.the percentage of regular sodas is 54 percent.you do this by timing 50 and 27 by 2 to get 100 and 54.

A recipe calls for 2/3 of cups of milk for 11 cookies. How many cups of milk are needed to make 165 cookies?
Answer:
10 cups of milk
Step-by-step explanation:
Make a proportion, where x is the number of cups of milk for 165 cookies:
[tex]\frac{2/3}{11}[/tex] = [tex]\frac{x}{165}[/tex]
Cross multiply and solve for x:
11x = 110
x = 10
So, 10 cups of milk are needed to make 165 cookies

Peter says, "If you subtract 12 from my number and multiply the difference by −7, the result is −175." What is Peter's number
Answer:
37
Step-by-step explanation:
let’s say peter’s number is x
(x-12)(-7) = -175
-7x + 84 = -175
-7x = -259
x = 259/7
x = 37
Answer:
The number is 37.
Step-by-step explanation:
-175 ÷ -7 = 25
25 + 12 = 37
You have to work backwards from -175 by doing the reverse of what peter did to get the original number.
