B

6/4=18/X
6x= 72
X=12

Or you can say 4+4+4=12

GEF~CBF, because <F is general and <GEF=<CBF=90°. => GE:CB=EF:BF=6:18=1:3
GE:CB=1:3
4:CB=1:3
CB=12
The answer is B

The equation of line L, is y = 5x + 1

Lynna [10]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 1 ← is in slope- intercept form

with slope m = 5

Rearrange 2y - 10x + 3 = 0 into this form

Add 10x to both sides

2y = 10x ( subtract 3 from both sides )

2y = 10x - 3 ( divide all terms by 2 )

y = 5x - $\frac{3}{2}$ ← in slope- intercept form

with slope m = 5

Since both lines have a slope of 5 then they are parallel.

Given the following acceleration function of an object moving along a line, find the position function with the given initial ve

Nezavi [6.7K]

Answer:

Position function is $s(t)=-12t^2$

Step-by-step explanation:

Given $a(t)=-24$ , since velocity is the antiderivative of acceleration, then $v(t)=-24t$ .

Also, since position is the antiderivative of velocity, then $s(t)=-12t^2$ .

Given f(x) shown below complete the equation for the inverse of f(x) = x-1

shtirl [24]

Replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)

f(x)=x-1
y=x-1
x=y-1
x+1=y
x+1=f⁻¹(x)
f⁻¹(x)=x+1
