Answer:

14x+3=8x+3

14x+3 -3 = 8x+3 -3

Cancels out the 3

14x = 8x

14x - 8x = 8x -8x

Cancels out the 8x

14x = 0

x = 0

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Masteriza [31]

Answer:

For the box that you did not fill out the area of that shape is 190 sq units

Step-by-step explanation:

10 x 5 = 50 ÷ 2 = 25

10 x 15 = 150

10 x 3 = 30 ÷ 2 = 15

25 + 150 + 15 = 190

Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of ?

Darina [25.2K]

Answer:

y – 2 = (x – 3)

Step-by-step explanation:

because (3, 2) was the point used for the equation but turned negative because you need to make it negative for the equation. y - y1 =m(x - x1)

Write the equation of the line in fully simplified slope-intercept form.

fiasKO [112]

$y = -\frac{1}{2}x - 1$

Step-by-step explanation:

Let's pick two points on the line: $P_1(-4, 1)$ and $P_2(2, -2).$ Let's calculate the slope of this line using these points:

$m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}$

With this value of the slope, we can write the general slope-intercept form of the equation as

$y = -\frac{1}{2}x + b$

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

$-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1$

Therefore, the slope-intercept form of the equation is

$y = -\frac{1}{2}x - 1$

What is the exact area of a circle having diameter 3 in.?

boyakko [2]

Answer:

2.25π square inches

Step-by-step explanation:

Area = π $r^{2}$

Diameter = 2r

So in this case, radius = 1.5 inches

Plugging that into the area formula produces the answer
