please answer, it’s a test

y= -1/7x - 3 :))))))))))))

Answer:

1) x + 4 = 11

Subtract 4 on both sides, to get x = 7 .

2) x + 3 = 24

Subtract 3 on both sides, to get x = 21 .

3) 4x = 12

Divide 4 on both sides, to get x = 3 .

4) 5x + 3 = 33

First subtract 3 on both sides to get

5x = 30, now divide 5 on both sides, to

get x = 6 .

5) 8x + 5 = 3x + 20

First subtract 5 from 20 in order to

move it, now you have 8x = 3x + 15 .

Next subtract 3x from 8x in order to

move it, now you have 5x = 15 . Lastly

divide 5 on both sides, to get x = 3 .

1) 1/2 x = 4

Multiply both sides by 2, to get 1x = 8,

or x = 8 .

2) 4/3 x = 4

Multiply both sides by 3, to get 4x = 12 .

Next divide 4 on both sides to get

x = 3 .

3) 2x + (-4) = 8

Add 4 on both sides, to get 2x = 12 .

Next divide 2 on both sides to get

x = 6 .

4) 1/3 x + 1/2 x = 20

First multiply the denominators to get a

common denominator of 6 and then

add 3 and 2, to get the numerator. Now

you have 5/6 x = 20 . Next multiply 6

on both sides to get 5x = 120 . Lastly

divide 5 on both sides to get x = 24 .

5) 1/3 x = 1/5 x + 10

First multiply the denominator to get a

common denominator of 15 and then

subtract 3 from 5 to get the numerator.

Now you have 2/15 x = 10 . Next

multiply 15 on both sides to get

2x = 150. Lastly divide 2 on both sides

to get x = 75 .

Hope this helped :)

Answer:

10

Step-by-step explanation:

This can be calculated correctly using BIDMAS. This stands for Brackets, Indices, Multiply, Divide, Add, Subtract. Using BIDMAS will allow us to know what order to answer the question in.

In BIDMAS, Divide comes before Add, so we know to do this part first. So we do 8 divided by 2 which is 4.

The next part of our question is to add 6, so we do 6+4=10. So, 10 is the final answer.

Answer:

1/6

Step-by-step explanation:

Start be rewriting your fractions with a common denominator

Multiply [tex]\frac{1}{2}[/tex] by [tex]\frac{6}{6}[/tex] to get [tex]\frac{6}{12}[/tex]

Multiply [tex]\frac{1}{3}[/tex] by [tex]\frac{4}{4}[/tex] to get [tex]\frac{4}{12}[/tex]

These are the fractions of the pizza eaten in twelfths like the pizza is cut into.

Now subtract from [tex]\frac{12}{12}[/tex] which is the whole pizza to find the pizza remaining

[tex]\frac{12}{12} -\frac{6}{12}-\frac{4}{12} =\frac{12-6-4}{12} =\frac{2}{12} =\frac{1}{6}[/tex]

The values of the letters in coordinates (a, b) and (c,d) are;

a = -4

b = -6

c = 2

d = 6

We are given two equations;

-6x + 3y = 6  ---(eq 1)

x² + y = 10 ---(eq 2)

Let us make y the subject in eq 2 to get;

y = 10 - x²  --(eq 3)

-6x + 3(10 - x²) = 6

expanding further gives;

-6x + 30 - 3x² = 6

rearranging gives;

3x² + 6x - 24 = 0

Using online quadratic equation solver, we have;

x = -4 and x = 2

Putting x = -4 into eq 3 gives;

y = 10 - (-4)²

y = 10 - 16

y = -6

Putting x = 2 into eq 3 gives;

y = 10 - (2)²

y = 10 - 4

y = 6

Comparing with (a, b) and (c,d), we have;

a = -4

b = -6

c = 2

d = 6

Answer:

m=11, x=6, h=5 2/3

Step-by-step explanation:

8(m-5) = 48

m-5 = 48/8 = 6

m = 6+5 = 11

m = 11

x + 7 = 13

x = 13-7 = 6

x = 6

3h - 5 = 12

3h = 12 + 5 = 17

h = 17/3 = 5 2/3 or 5.67

10^-n means to divide by 10 or multiply by 1 / 10

So .0009763 means 9.763 / 10000 = 9.763 * 10-4

The 'y' is increasing by 4 every time 'x' is going up by 1

Answer:

(0,-1); (0,-2); (2,0); (2,-2)

Step-by-step explanation:

when rotating 180 degrees all the points have their coordinate sign's flipped.

so the points go from:

(0,1) --> (0,-1)

(0,2) --> (0,-2)

(-2,0) --> (2,0)

(-2,2) --> (2,-2)

so your new shape will have the points (0,-1); (0,-2); (2,0); (2,-2)

Answer:  y = -(4/3)x + 1

Step-by-step explanation:

Let's start with finding an equation of a straight line (y=mx+b) that goes through points (-2,1) and (6,7).

The slope of a line, m, is the change in y for the change in x, or Rise/Run.

This is derived from the two points.

Rise (7-1) = 6

Run (6 - (-2)) = 8

Rise/Run = 6/8 or 3/4

The line is therefore y = (3/4)x + b

Find b by using one of the two points.  I'll use (-2,1), but the other would also work.

y = (3/4)x + b

1 = (3/4)(-2) + b

1 = -(6/4) + b

b = 10/4

The line becomes y = (3/4)x + 10/4

--------

A line perpendicular to this will have a slope that is the negative inverse of the original line.  The negative inverse of (3/4) is -(4/3).

The perpendicular line will be:

y = -(4/3)x + b

Use point (-6,9) to find b:

y = -(4/3)x + b

9 = -(4/3)*(-6) + b

9 = (24/3) + b

b = (27/3 - 24/3) = 3/3 = 1

The line is y = -(4/3)x + 1
