When we are talking about dilation of objects, it just means shrinking or enlarging an object by a scale factor. This means ratio of corresponding sides of both objects must be equal.
A) Ratio of corresponding longer side = 4/8 = ½
Ratio of corresponding shorter side = 2/4 = ½
Thus, this shows a dilation.
B) This involves a square and a rectangle. They are not the same because all sides of the square are equal but not all sides of the rectangle are equal. Thus, a dilation is not possible.
C) the ratio of the corresponding sides are not equal and as such it is not dilated.
D) The ratio of the corresponding sides are not equal and as such it is not dilated.

is –2x + 3 = 4y linear, if so write in standard form.
Answer:
Yes, it is linear. y=-1/2x+3/4
Step-by-step explanation:
To put it in standard form, you need to get the y by itself.
4y=-2x+3
Divide by 4.
y=-1/2x+3/4
Find the slope of the line
Answer:
Slope is just what is y/x so y=4-3=1, X=3-(-2)=5, remember if you use point 1's y to minus point 2, for x you also need to use point 1's x to minus point 2's x. So it's 1/5
Answer:
Step-by-step explanation:
2) (0,3) ; (3, 2)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{2-3}{3-0}\\\\=\frac{-1}{3}[/tex]
3)(-2, 1) (3,4)
Slope = [tex]\frac{4 -1}{3-[-2]}[/tex]
[tex]=\frac{4-1}{3+2}\\\\=\frac{3}{5}[/tex]

Step-by-step explanation:
Determine whether the graph represents a proportional or non-proportional relationship. Then select the correct equation in the form y=mx or y=mx+b to represent the relationship between the independent and dependent quantities.
This graph is an example of a blank area relationship. The equation that represents the relationship between the independent and dependent quantities is blank area.
Unproportional
Proportional
y=5x+20
y=60x
y=x+30
Help me fill in the blanks that say blanks
Answer:
Non-proportional
y = [tex]\frac{2}{15}x+20[/tex]
Step-by-step explanation:
If a line doesn't pass through the origin relationship represented by the line is non proportional.
In other words, any line having y-intercept is non-proportional.
From the graph attached,
Line has a y-intercept = 20
Therefore, relationship is non-proportional.
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Since, the given line is passing through (0, 20) and (60, 28),
Slope of the line 'm' = [tex]\frac{28-20}{60-0}[/tex]
m = [tex]\frac{8}{60}[/tex]
= [tex]\frac{2}{15}[/tex]
y-intercept 'b' = 20
Slope-intercept form of the equation is,
y = mx + b
So the equation will be,
y = [tex]\frac{2}{15}x+20[/tex]

Which graph is and is not a function!?
Answer:
The first one is a function. The other two are not functions.
Step-by-step explanation:
To find this, you use the vertical line test. If the vertical line touches multiple points on the graphed line, it is not a function. If the vertical line only touches the graphed line at one point, it is a function.
Good Luck! I hope this helps!

Which statements are true about function g?
Function g is increasing over the entire domain.
As x approaches negative infinity, approaches positive infinity.
Function g includes an exponential piece and a quadratic piece.
As x approaches positive infinity, approaches positive infinity.
Function g is continuous.
Answer:
B, D, and E.
B: As x approaches negative infinity, g(x) approaches positive infinity.
D: As x approaches positive infinity, g(x) approaches positive infinity.
E: Function g is continuous.
Step-by-step explanation:
To answer this question, we will graph it. Please refer to the graph below.
Let’s go through each of the answer choices.
A) Function g is increasing over the entire domain.
Looking at the graph, we can see that this is not true.
More specifically, the red curve is decreasing over its entire interval.
So, A is not correct.
B) As x approaches negative infinity, g(x) approaches positive infinity.
This is true. As x approaches negative infinity i.e. as we go towards the left of the graph, we can see that our function g(x) (the red curve) is approaching positive infinity.
C) Function g includes an exponential piece and a quadratic piece.
This is false. The first piece is indeed exponential, but the second piece is a cubic, not a quadratic.
D) As x approaches positive infinity, g(x) approaches positive infinity.
Again, this is true. As x approaches positive infinity i.e. As we go towards the right of the graph, we can see that our function g(x) (the blue curve this time) is approaching positive infinity.
E) The function is continuous.
For a function to be continuous, it must have no breaks, jumps, and/or gaps.
We can see that our function does not possess any of the above.
So, g(x) is continuous.
Therefore, the correct statements are B, D, and E.

howhowhow?how??? how would you calculate
if 1. was 32, how would you got 32 from '40% of 80'
Ok sooooooooooo
Lets say your two fractions are
13/26 and 20/40
you can divide the bottom number by the top one and if you get the same answer for both then they are equivalent. For these you get 2 for both, which means they are equivalent.
another example would be if your fractions are
2/5 and 4/10
You can say well 2*2 equals 4 And 5*2 equals ten so these are equivalent fractions.

What is the y-intercept of the line?
Answer:
1
Step-by-step explanation:
the line crosses the y-axis at the point (0, 1), which is a y-intercept because x=0, so the y-intercept would be 1
