Answer:
2 x 2 x 2 x 2 x 2, which can also be written 32 = 2⁵
Step-by-step explanation:
6x + 4y = 24
2x - 4y = -8
We will use the addition method in solving this system of equation.
6x + 4y = 24
+ (2x - 4y = -8)
8x + 0 = 16
8x = 16
x = 16/8
x = 2
Let us substitute x by its value to get the value of y.
6x + 4y = 24
→ 6(2) + 4y = 24
12 + 4y = 24
4y = 24 - 12
4y = 12
y = 12/4
y = 3
2x - 4y = - 8
→ 2(2) - 4y = - 8
4 - 4y = - 8
-4y = - 8 - 4
-4y = -12
y = -12/-4
y = 3
So x = 2 and y = 3. → (2,3)
The true statement among the choices are:
A) The ordered pair that is the solution to the system lies in Quadrant I .
<span>B) The y-coordinate of the solution is 3.
</span><span>D) The x-coordinate of the solution is 2.</span>
Answer: 168
Step-by-step explanation:
1. -9 * 14 = -126
2. -126/ -0.75 = 168
Answer:
1 6/9
Step-by-step explanation:
Answer:
$40
Step-by-step explanation:
If you were to purchase 7 picture frames, you would replace x in the equation with 7, this is shown below.
<u>f(x)=9x-23 ---> f(x)=9(7)-23</u>
Now we can solve for f(x). First start with 9(7).
<u>f(x)=9(7)-23 ---> f(x)=63-23</u>
Now finish the last part by subtracting 23 from 63.
<u>f(x)=63-23 ---> f(x)=40</u>
This means that you would have to pay $40 dollars to purchase the 7 picture frames.
