Answer:

1/2

Step-by-step explanation:

Pick two points

(0,1) and (2,2)

The slope is

= (2-1)/(2-0)

= 1/2

Answer:

x^2 +11x +30

Step-by-step explanation:

(x+6) * ( x+5)

The blue area is x^2

pink is 6x

green is 5x

orange is 5*6 = 30

Add them together

x^2 +6x+5x+30

x^2 +11x +30

10. angle GHI is an isosceles triangle with GI HI. IF GH is three more than x, HI is 17 less than four

svp [43]

Answer:

GH = 17 units

GI = 39 units

HI = 39 units

Step-by-step explanation:

We are given the following information in the question:

Triangle GHI is an isosceles triangle.

$GI = HI$

The measures of side are:

$GH = 3 + x\\HI = 4x-17\\GI = 6x - 45$

It is given that

GI = HI

$4x - 17 = 6x -45\\6x - 4x = 45-17\\2x = 28\\x = 14$

Thus, the measures of three sides are:

$GH = 3 + x=14+3 = 17\\HI = 4x-17 = 4(14)-17 = 39\\GI = 6x - 45=6(14) - 45 = 39$

The width of a rectangle is 3 units less than the length. The area of the rectangle is 28 units. What is the width, in units, of

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Let's call the width W and the length L.

We know the width is 3 less than the length, so:

W = L - 3

And we know the area is 28, so:

28 = WL

If we solve for L in the first equation:

L = W + 3

And substitute into the second equation:

28 = W (W + 3)

28 = W² + 3W

0 = W² + 3W - 28

0 = (W + 7) (W - 4)

W = -7, 4

Since W can't be negative, W = 4 units.
