Answer:
(3,2)
Step-by-step explanation:
5x+2y= 19
4x - 3y = 6
I will use elimination
Multiply the first equation by 4
20x +8y = 76
Multiply the second equation by -5
-20x +15y = -30
Add them together to eliminate x
20x +8y = 76
-20x +15y = -30
---------------------------
23y = 46
Divide by 23
23y/23 = 46/23
y =2
Now find x
5x+2y =19
Substitute y=2
5x+2(2) =19
5x+4 = 19
Subtract 4 from each side
5x +4-4 =19-4
5x= 15
Divide by 5
5x/5 = 15/5
x=3
The solution is
(3,2)
7 > x/4
Step 1) we multiply each side by 4
7 times 4, 4 times x/4
28> x
Answer:
Step-by-step explanation:
We are given that a student needs to make a square cardboard piece.
Perimeter of cardboard should be equal to atleast 92 inches
We have to find that which shows reasonable domain for f(s)
Let s be the side of square cardboard
We know that perimeter of square =f(s=)
Then, perimeter of cardboard=
Dividing by 4 on both sides
Hence, the domain of function
Therefore, option d is true.
Answer:d:
(g-f)(x) is x² - 3x - 6
<u>Step-by-step explanation:</u>
Step 1:
Given g(x) = x² - 1 - 2x, f(x) = x + 5. Find (g-f)(x)
(g-f)(x) = x² - 2x - 1 - (x + 5) = x² - 2x - 1 - x - 5 = x² - 3x - 6
