Answer:

56 tests

Step-by-step explanation:

first find the amount of test he took each week. if we divide 12 by 6 (12 ÷ 6 = 2) we find out that he took 2 tests per week.

So if he continues with the same rate for the next 28 weeks of school, in order to find out how many tests he would have taken, we just need to  multiply 28 by 2 (28 × 2 = 56), which will be equal to 56

hope this helps! if you have any questions, let me know!

The following table shows the length and width of two rectangles:
faltersainse [42]
The perimeter of these can be found by adding length and width and then multiplying by two. 

Rectangle A: (with all of the variables already doubled)
2x + 16 + 2x - 2 
2x + 2x + 16 - 2
4x + 14
So rectangle A's perimeter is 4x + 14.

Rectangle B: (Still with all the variables already doubled)
8x + 10 + 6x - 4
8x + 6x + 10 - 4
14x + 6
So rectangle B's perimeter is 14x + 6

And now to subtract the two.
(7x + 3) - (4x + 14)
14x + 6 - 4x - 14
14x - 4x + 6 - 14
10x - 8

So it would be C.

Solve the equation 2(x-4)=-22
Tcecarenko [31]

Hello Lexi!

<u><em>Answer:  ⇒⇒⇒⇒⇒⇒ x=-7</em></u>

__________________________________________________________

Step-by-step explanation:

First you had to divide by 2 from both sides of equation.

\frac{2(x-4)}{2}=\frac{-22}{2}

Simplify.

\frac{2(x-4)}{2}=x-4

\frac{2(x-4)}{2}

Divide by the numbers.

\frac{2}{2}=1

=x-4

\frac{-22}{2}=-11

Apply the fraction rule.

\frac{-22}{2}

=-\frac{22}{2}

Then you divide by the number.

\frac{22}{2}=11

=-11

x-4=-11

Add by 4 from both sides of equation.

x-4+4=-11+4

Simplify it should be the correct answer.

x=-7

Hope this helps!

Have a great day!

Answer:

x=12 y=3

Step-by-step explanation:

Since the scale factor is 1:3, that means that the length and width of Q multiplied by 3 gives the corresponding length and width of P.

Similarly, the length and width of P divided by 3 gives the corresponding length and width of Q.

With this, 9/3=3, which is the value of y.

4*3=12, which is the value of x.

What happens when x is a very small negative number?
marshall27 [118]

With this line, we see that when x is a small negative number, F(x) is a very large negative number, or B.

Remember that F(x) is the same as y. And looking at the pattern of the line, the greater the negative x is, the smaller the negative y is.
