Help please. I attempted, but I couldn't succeed.
german

Answer:

y=(3/2)x+-14

First blank: 3

Second blank:2

Last blank:-14

Step-by-step explanation:

The line form being requested is slope-intercept form, y=mx+b where m is slope and b is y-intercept.

Also perpendicular lines have opposite reciprocal slopes so the slope of the line we are looking for is the opposite reciprocal of -2/3 which is 3/2.

So the equation so far is

y=(3/2)x+b.

We know this line goes through (x,y)=(4,-8).

So we can use this point along with our equation to find b.

-8=(3/2)4+b

-8=6+b

-14=b

The line is y=(3/2)x-14.

What is the unit rate $1.99 for 30 oz to nearest tenth
KatRina [158]

Answer:

$0.10/oz

Step-by-step explanation:

Unit rate simply means the amount per 1 unit of something.

In this case, we want to find the amount of money for 1 oz of something.

So, we divide 1.99 by 30 and divide 30 by 30 to get:

(1.99 / 30) / (30 / 30) = $0.0663 / 1 oz

Rounded to the nearest tenth, 0.0663 is about 0.1.

Thus, the answer is $0.10/oz.

The system of equations is solved using the linear combination method.
Alborosie

The interpretation of 0 = -12 is (a) There are no solutions to the system because the equations represent parallel lines.

<h3>How to interpret the result?</h3>

The result is given as:

0 = -12

By comparison 0 and -12 do not have the same value

i.e. 0 ≠ - 12

This means that the system of equation has no solution

Hence, the interpretation of 0 = -12 is (a)
