Answer:

This formula can also be written as $y - {y}_{1} = m\left(x - {x}_{1}\right)$. The standard form of the straight line equation is $y = mx + c$ where $m$ is the gradient and $c$ is the $y$-intercept.

-3|x|+2x-1 if x=-5 plz help

Savatey [412]

Answer:

f(x) = -3|x| + 2x - 1

f(-5) = -3|-5| + 2*(-5) - 1

= -3*5 + 2*(-5) - 1

= -15 - 10 - 1

= -26

Hope this helps!

A circular merry-go-round has a radius of 5 feet. Find the distance of a spin of one full rotation. Use 3.14 for pi and round th

Sedbober [7]

Option C

The distance of a spin of one full rotation is 31.4 feet

Solution:

Given that,

A circular merry-go-round has a radius of 5 feet

Radius = 5 feet

We have to find the distance of spin for one full rotation

Distance covered in 1 full of rotation is equal to circumference of circle

The circumference of circle is given as:

$C = 2 \pi r$

Where "r" is the radius

$C = 2 \times 3.14 \times 5\\\\C = 6.28 \times 5\\\\C = 31.4$

Thus the distance of a spin of one full rotation is 31.4 feet

DaniilM [7]

J=15b/10g

S=21b/g w/ the ratio 3/2 (15/10=3/2)

1) Form an equation (21/g=3/2).

2) Since you are trying to find the denominator, multiply 3/2 so that the numerators are the same (3×7=21 2×7=14).

3) The answer will be whatever the denominator is at the end.

The answer is there are 14 girls in Steven's class.
