Answer:

1/3

Step-by-step explanation:

You need to use slope formula. (the change in Y over the change in X = Slope [x1-x2/y1-y2 = slope]). I believe you can also use point slope formula, but I forgot how to do that one.

First, you would set up the equation.

7-9/-2-4 OR 9-7/4+2

you would then solve to get

-2/-6 OR 2/6

when simplified you get

1/3

for both. Hope it helps!

Answer:

Step-by-step explanation:

slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{9-7}{4-(-2)}\\\\=\frac{2}{4+2}\\\\=\frac{2}{6}=\frac{1}{3}

Answer:

80 m²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (a + b)

where h is the perpendicular height between bases and a, b are the bases

Here h = 8, a = 14 and b = 6, thus

A = \frac{1}{2} × 8 × (14 + 6) = 4 × 20 = 80 m²

X+(3x+2)+(1)/(2)x=29
Vladimir79 [104]

Answer:

\boxed{x=6}

Step-by-step explanation:

x+3x+2+0.5x=29

\sf Combine \ like \ terms.

4.5x+2=29

\sf Subtract \ 2 \ from \ both \ sides.

4.5x+2-2=29-2

4.5x=27

\sf Divide \ both \ sides \ by \ 4.5.

\displaystyle \frac{4.5x}{4.5} =\frac{27}{4.5}

x=6

I don't really understand this​
KonstantinChe [14]

Answer:

6

Step-by-step explanation:

the question says that (Patricia) is covering a table with a table cloth, the table has a diameter of 6.

Diameter is defined as the length of a straight line through the center of a circle. An example of diameter is the length of a line sliced down the center of a pie.

so the question asks how much surface is covered by the table cloth? simply it is six.

Find the midpoint P(16,7) and Q(12, -3) With work.
hichkok12 [17]

Answer:

(14, 2 )

Step-by-step explanation:

Use the midpoint formula

[0.5(x₁ + x₂), 0.5(y₁ + y₂) ]

with (x₁, y₁ ) = (16, 7) and (x₂, y₂ ) = (12, - 3)

midpoint = [0.5(16 + 12), 0.5(7 - 3) ] = [0.5(28), 0.5(4) ] = (14, 2 )
