Answer:

True

Step-by-step explanation:

y = 2x-8

This equation is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

2 is the slope and -8 is the y intercept

Answer:

True.

Step-by-step explanation:

The slope-intercept form is: y = mx + b

<em>m</em> = slope (or 2 in this case)

<em>b</em> = y-intercept (or -8 in this case)

y & x comes from the coordinates (y, x).

Answer:

C: $x=-3$ or $x=4$

Step-by-step explanation:

To solve the equation $x^2-x-12=0$ we need to factor it

We are looking for two numbers that when multiplied give -12 and when added give -x

This means that when factored, the equation would be $(x-4)(x+3)=0$

Now we can set each of these equal to 0, which means that at

$x=-3$ and $x=4$ , the equation will equal 0

The dimensions of a rectangular garden is 3 m by 10 m. When both dimensions are increased by equal amounts, the area of the gard

Ksju [112]

Answer:

5 by 12 m

Step-by-step explanation:

The area for rectangle is LxW

The original area is 3*10, or 30 meters.

When both dimensions are increased, now the area is 60.

We can now inch up slowly to see what works:

3.5 and 10.5=36.75 X

4 and 11=40 X

5 and 12=60 YES!

The new dimensions of the garden are 5 m by 12 m, increased by 2, and the new area is 60 meters^2.
