Write an equation of the line that is parallel to the given line y = 2x + 3 and the given point (-4,1).

1 answer:

7 0

Parallel lines has equal slopes.

Line y = 2x + 3 has a slope of 2.

Required equation is y - 1 = 2(x + 4)
y = 2x + 8 + 1
y = 2x + 9

Find the length of arc JM

hoa [83]

Answer:

JM ≈ 12.9 miles

Step-by-step explanation:

The length of the arc is calculated as

arc = circumference × fraction of circle

= πd × $\frac{90}{360}$

JM = π × 16.4 × $\frac{1}{4}$

= $\frac{16.4\pi }{4}$ ≈ 12.9

For the inverse variation equation xy = k, what is the value of x when y = 4 and k = 7? 3 28

Oliga [24]

Answer:

The value of x is $\frac{7}{4}$ .

Step-by-step explanation:

It is given that the inverse variation equation is

$xy=k$ ..... (1)

The value of y is 4 and the value of k is 7.

Substitute y=4 and k=7 in equation (1).

$x\times 4=7$

Divide both sides by 4.

$\frac{x\times 4}{4}=\frac{7}{4}$

$x=\frac{7}{4}$

Therefore the value of x is $\frac{7}{4}$ .

What is the value of n in the equation 0.2(n - 6) = 2.8?<br> (1) 8 (3) 20<br> (2) 2 (4) 44

Vera_Pavlovna [14]

So,

0.2(n - 6) = 2.8

Distribute.
0.2n - 1.2 = 2.8

Add 1.2 to both sides.
0.2n = 4

Divide both sides by .2.
n = 20

Check.
0.2(20 - 6) = 2.8

Simplify inside parentheses.
0.2(14) = 2.8

Multiply.
2.8 = 2.8 This checks.

S = {2.8}
