SVEN [57.7K]

Answer:

A <em> </em><em>and</em><em> </em><em>E</em><em> </em><em>is</em><em> </em><em>true</em><em>. </em><em>BCD</em><em> </em><em>is</em><em> </em><em>False</em>

Step-by-step explanation:

Let convert this into slope intercept form

10y - 200x = 500

10y = 200x + 500

y = 20x + 50

So now let answer these questions,

A is TRUE the slope is the number in front of the x value. It is 20 so a is true.

B is False, Using (0, 500) The equation is wrong

500 = 20(0) + 50 ??

C is false, we have a positive slope so it shifts upward from left to right.

D is false

the slope isn't 200.

E Is true the y intercept is when the x value is 0, what is the y value so plug it in we get

y = 20(0) + 50

It equal 50.

Clair collects seashells. At home, she has 15 shells. Every day she brings 3 back to the beach. After 5 days how many seashells
Igoryamba

The equation would be:

y = 3x + 15

1) Table: It is pretty easy to do so, just plug in 0, 1, 2, 3, etc. for x and solve for y

2) graph (find slope): slope would be 3 shells/day that has a y-intercept of 15

3) you already defined the variables

4) 3(5)+15 = 15+15 = 30 seashells

I hope this helps!

144 = -12 (x + 5)<br><br> find x<br><br> Show work.
kumpel [21]

Answer:

-17 =x

Step-by-step explanation:

144 = -12 (x + 5)

Divide each side by -12

144/-12 = -12 (x + 5)/-12

-12 = x+5

Subtract 5 from each side

-12-5 =x+5-5

-17 =x

Answer:

Eliza is 1

Step-by-step explanation:

If Eliza is 2 years younger than 1/2 her brothers age and Juan is 6.

  • - divide 6 by 2 (6÷2=3)
  • - Take 3 away from 2 ( 3-2=1)

So that means Eliza would be 1
