6 0

Answer:

2d(d - 4)

Step-by-step explanation:

Given

2d² - 8d ← factor out the common factor of 2d from each term

= 2d(d - 4) ← in factored form

Here's a graph of a linear function. Write the equation that describes that function. 8 Express it in slope intercept form. Ente
Stolb23 [73]

Answer:

f(x) = \frac{1}{2}x+4

Step-by-step explanation:

Let the equation of the function is,

f(x) = mx + b

Here, m = slope of the line

b = y-intercept

From the graph attached,

y-intercept 'b' = 4

Slope = \frac{\text{Rise}}{\text{Run}}

          = \frac{4}{8}

          = \frac{1}{2}

Therefore, equation of the function representing the graph will be,

f(x) = \frac{1}{2}x+4

A right cubic prism has edges of 2 1/2 inches. How
3241004551 [841]

Answer:

Option D, the volume is 15.625 cubes

Step-by-step explanation:

For a cube of side length L, the volume is:

V = L^3

for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:

v = (1in)^3 = 1 in^3

Then:

1 in^3 is equivalent to one small cube

Here we know that the side length of our cube is (2 + 1/2) in

Then the volume of this cube will be:

V = [ (2 + 1/2) in]^3

To simplify the calculation, we can write:

2 + 1/2 = 4/2 + 1/2 = 5/2

Then:

V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3

This means that 15.625 small cubes will fill the prism.

So the correct option is D.

5x + 7 - 2(-8x -1) = 7(x - 1)
love history [14]

Step-by-step explanation:

5x + 7 - 2( - 8x - 1) = 7(x - 1)  \\ 5x + 7 + 16x + 2 = 7x - 7 \\ collecting \:  like \:  \: terms \:  \\ 5x + 16x - 7x =  - 7 - 2 - 7 \\ 14x =  - 16 \\ divide \: both \: side \: by \: 14 \\  \frac{14x}{14}  =  \frac{ - 16}{14}  \\ x =   - \frac{ 8}{7}

19. Heather invests $4,900 in an account with a 3.5% interest rate, making no other deposits or withdrawals. What will Heather’s
denis-greek [22]

Answer:

\$5,828.28

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=5\ years\\ P=\$4,900\\ r=0.035\\n=2  

substitute in the formula above  

A=\$4,900(1+\frac{0.035}{2})^{2*5}  

A=\$4,900(1.0175)^{10}=\$5,828.28
