Which equation represents a line that is parallel to y=-4x+3 and that passes through the point (-1, 2)?

belka [17]

A parallel line will have the same slope, which is -4. So the answer so far cannot be A or B.
Put x=-1 in each of C and D and we get y=2 for C and y=1 for D. Since the point is (-1,2) the answer is C.

Rewrite –220° in radians. Write the solution as a fraction in simplest form.

son4ous [18]

Answer:

- $\frac{11\pi }{9}$

Step-by-step explanation:

To convert degrees to radians

radian measure = degree measure × $\frac{\pi }{180}$ , then

radian measure = - 220 × $\frac{\pi }{180}$ ( divide 220 and 180 by 20 )

= - $\frac{11\pi }{9}$

The given expression $8(4)^2+2^4$ is equal to 144 or $12^2$

<em><u>Solution:</u></em>

Given expression is:

$8(4)^2+2^4$

We have to evaluate the above given expression

We know that,

$(4)^2 = 4 \times 4 = 16$

$2^4 = 2 \times 2 \times 2 \times 2=16$

Substituting these in above given expression, we get

$8(4)^2+2^4=8 \times 16+16\\\\8(4)^2+2^4= 128+16\\\\8(4)^2+2^4=144$

Also we know that,

$12 \times 12 = 144$

Therefore,

$8(4)^2+2^4=144 = 12 \times 12 = 12^2$

Thus the given expression $8(4)^2+2^4$ is equal to 144 or $12^2$

Find the average rate of change from x = 3 to x = 15 for the function f(x) = 0.01(2)x and select the correct answer below.

Nesterboy [21]

x=3:

0.01*2^3 = 0.08

x=15:

0.01*2^15 = 327.68

327.68 - 0.08 = 327.60

15-3 = 12

327.6/12 = 27.3

Answer is C
