Allison has a poster that is 15 in by 18 in. What will the dimensions of the poster be if she scales it down by a factor of 1/3

Answers

Answer 1

Answer: If you minus one third from 15 and one third from 18, the dimensions would be 10 x 12

15÷3 = 5
18÷3 = 6
15 - 5 = 10
18 - 6 = 12

What is the equation of the following graph in vertex form?the graph shows a positive parabola with the vertex at, (-1,0) and passes through (0,1) and (-2,1)
Answers
y = (x − 1)2
y = (x − 1)2 + 1
y = (x + 1)2 − 1
y = (x + 1)2

Answers

Vertex form uses the following formula:

$a(x-h)^2 + k$

a determines the stretch of the parabola. h and k are the x and y values of the vertex (h, k), respectively.

The vertex is at (-1, 0). There is no a value indicated for any answer. Plug these values into the equation:

$\text{h = -1, k = 0}$

$(x - (-1))^2 + 0$

$\boxed{(x+1)^2}$

The answer is (x+1)^2.

Answer:

(x+1)^2

Step-by-step explanation:

the difference between two positive integers is 40. one integer is three times as great as the other. find the integer.

Answers

Be the integers: x and y

x - y = 40
x = 3y

Replace x in the first equation:

3y - y = 40
2y = 40
y = 20
x = 60

Solve by substitution
