Given that:

f(x) = -2x²-2x+10

f(2) = -2(2)²-2(2)+10

= -2(2*2) - 4 + 10

= -2(4) - 4 + 10

= -8 - 4 + 10

= -12 + 10

= -2 Ans.

To get the area of a rectangle, multiply the side lengths.
Our side lengths of this rectangle is 1/2 and 3/4, so let's multiply them.

\dfrac{1}{2} *  \dfrac{3}{4} =  \dfrac{3}{8}

Thus, the area of this rectangle is 3/8 ft². I hope this helps! :)

A pair of shoes usually sells for $61. If the shoes are 40% off, and sales tax is 8%, what is the total price of the shoes, incl
Pie

Answer:

3952.8$

Step-by-step explanation:

61$ : 100 = x : 60% (since it is 40% off, the remaining is 60% of the price)

100x : 61 x 60

100x : 3360

3360 divided by 100

x = 36.6

36.6 : 100% = x 108%

100x : 36.6 x 108

x = 3952.8

3952.8 divided by 100

39.528

Gavin thought he was making a good investment when he heard about an online grocery company. So he brought 500 shares in a compa
Oksanka [162]
Originally, the 500 shares were worth 25 bucks a share. If he only made $150 with 500 shares, the shares were worth $0.30 a share. So, subtract $0.30 from $25 to get $24.70. Divide 24.7 by 25 to get 0.988. Multiply this by 100 to change it into a percent. The share price decreased 98.8%.

What is an equation of the line that passes through the points (2, -7) and (8, -4)?
Virty [35]

Answer:

The answer is

<h2>y =  \frac{1}{2} x - 8</h2>

Step-by-step explanation:

To find the equation of the line that passes through two points , first find the slope and then use the formula

y - y1 = m(x - x1)

where m is the slope

(x1 , y1) are any of the points

To find the slope of the line using two points we use the formula

m =  \frac{y2 - y1}{x2 - x1}

Slope of the line using points

(2, -7) and (8, -4) is

<h3>\frac{ - 4 + 7}{8 - 2}  =  \frac{3}{6}  =  \frac{1}{2}</h3>

Now the equation of the line using point (2 , - 7) and slope 1/2 is

<h3 /><h3>y + 7 =  \frac{1}{2} (x - 2)</h3><h3 /><h3>y + 7 =  \frac{1}{2} x - 1</h3><h3>y =  \frac{1}{2} x - 1 - 7</h3><h3 />

We have the final answer as

<h3>y =  \frac{1}{2} x - 8</h3>

Hope this helps you
