FINAL DUE IN 30 MINUTES: the equation 2y + x = 0 is shown on the graph below as a

julia-pushkina [17]

Answer:

Red line

Step-by-step explanation:

2y+x=0

2y=-x

y=-x/2

Put the equation into y=mx+b so you would need to subtract the x to put it on the right side so then you’ll have 2y=-x+0 then divide by 2 to get the y by itself then you’ll have y=-2x+0 that means the line would be negative and the y-intercept is 0 and the only line that follows that is the red line.

A parabola has an x-intercept of -1, a y-intercept of -3, and a minimum of -4 at x = 1.

torisob [31]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

$y=a(x-h)^{2}+k$

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(1,-4)

substitute

$y=a(x-1)^{2}-4$

we have

An x-intercept of (-1,0)

substitute and solve for a

$0=a(-1-1)^{2}-4$

$0=4a-4$

$4a=4$

$a=1$

The equation is

$y=(x-1)^{2}-4$

Verify the y-intercept

For x=0

$y=(0-1)^{2}-4$

$y=-3$

The y-intercept is the point (0,-3) -----> is correct

using a graphing tool

the perimeter of the triangle shown to the right is 154 meters. find the lenght of each side. (4x)m (7x+2)m (7x+8)m

yaroslaw [1]

The first to find the length of each side, we have to find the value of x :
$(4x) + (7x + 2) + (7x+8) = 154$

$4x + 7x + 7x + 2+8 = 154$

$18x +10 = 154$

$18x = 154 - 10$

$18x = 144$

$x = \frac{144}{18}$

$\boxed{x=8}$

Solution First side :
 $(4x)m = (4 \cdot 8)m = 32\ m$ 

Solution Second Side :
 $(7x+2)m = (7(8)+2)m = 58\ m$ 

Solution Third Side :
 $(7x+8)m = (7(8)+8)m = 64\ m$
