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

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.

Which is the inverse of the function a(d)=5d-3? And use the definition of inverse functions to prove a(d) and a-1(d) are inverse functions
Answer:
[tex]a'(d) = \frac{d}{5} + \frac{3}{5}[/tex]
[tex]a(a'(d)) = a'(a(d)) = d[/tex]
Step-by-step explanation:
Given
[tex]a(d) = 5d - 3[/tex]
Solving (a): Write as inverse function
[tex]a(d) = 5d - 3[/tex]
Represent a(d) as y
[tex]y = 5d - 3[/tex]
Swap positions of d and y
[tex]d = 5y - 3[/tex]
Make y the subject
[tex]5y = d + 3[/tex]
[tex]y = \frac{d}{5} + \frac{3}{5}[/tex]
Replace y with a'(d)
[tex]a'(d) = \frac{d}{5} + \frac{3}{5}[/tex]
Prove that a(d) and a'(d) are inverse functions
[tex]a'(d) = \frac{d}{5} + \frac{3}{5}[/tex] and [tex]a(d) = 5d - 3[/tex]
To do this, we prove that:
[tex]a(a'(d)) = a'(a(d)) = d[/tex]
Solving for [tex]a(a'(d))[/tex]
[tex]a(a'(d)) = a(\frac{d}{5} + \frac{3}{5})[/tex]
Substitute [tex]\frac{d}{5} + \frac{3}{5}[/tex] for d in [tex]a(d) = 5d - 3[/tex]
[tex]a(a'(d)) = 5(\frac{d}{5} + \frac{3}{5}) - 3[/tex]
[tex]a(a'(d)) = \frac{5d}{5} + \frac{15}{5} - 3[/tex]
[tex]a(a'(d)) = d + 3 - 3[/tex]
[tex]a(a'(d)) = d[/tex]
Solving for: [tex]a'(a(d))[/tex]
[tex]a'(a(d)) = a'(5d - 3)[/tex]
Substitute 5d - 3 for d in [tex]a'(d) = \frac{d}{5} + \frac{3}{5}[/tex]
[tex]a'(a(d)) = \frac{5d - 3}{5} + \frac{3}{5}[/tex]
Add fractions
[tex]a'(a(d)) = \frac{5d - 3+3}{5}[/tex]
[tex]a'(a(d)) = \frac{5d}{5}[/tex]
[tex]a'(a(d)) = d[/tex]
Hence:
[tex]a(a'(d)) = a'(a(d)) = d[/tex]
On Tuesday, Mr. Miles walked 2/9 of the trail to warm up and then he ran 4/6 of
the trail. What fraction of the trail did Mr. Miles cover on Tuesday?
Answer: 8/9
Step-by-step explanation:
From the question, we are informed that On Tuesday, Mr. Miles walked 2/9 of the trail to warm up and then he ran 4/6 of the trail.
The fraction of the trail that Mr. Miles covered on Tuesday would be the addition of both fractions. This would be:
= 2/9 + 4/6
Note that the lowest common multiple of 9 and 6 is 8. Therefore,
= 2/9 + 4/6
= 4/18 + 12/18
= 16/18
= 8/9
He covered 8/9 of the trail

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]

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.

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!
