Answer:
-11
Step-by-step explanation:
5x + 2 = 4x - 9. (1 point)
x=-9-2
x=-11
Solve your equation step-by-step.
5(2y−2)+4=4
Simplify both sides of the equation.
5(2y−2)+4=4
(5)(2y)+(5)(−2)+4=4(Distribute)
10y+−10+4=4
(10y)+(−10+4)=4(Combine Like Terms)
10y+−6=4
10y−6=4
Add 6 to both sides
.
10y−6+6=4+6
10y=10
Divide both sides by 10.
10y/10 = 10/10
Answer: C) x = 7, y = -1
Step-by-Step Explanation:
=> y = -2x + 13 (Eq. 1)
=> 4x + 8y = 20 (Eq. 2)
Substitute value of ‘y’ from Eq. 1 in 2 :-
4x + 8y = 20
4x + 8(-2x + 13) = 20
4x + -16x + 104 = 20
-12x + 104 = 20
-12x = 20 - 104
-12x = -84
12x = 84
x = 84/12
=> x = 7
Substitute value of ‘x’ in Eq. 1 :-
y = -2x + 13
y = -2(7) + 13
y = -14 + 13
=> y = -1
Therefore, x = 7, y = -1 which can be written in an ordered pair as (7,-1).
Answer:
x=-2
Step-by-step explanation:
3(8x+12)-15x=2(3-3x)
24x+36-15x=2
(3-3x
If this is represented by a linear function, then we know that the amount of money decreases at an unchanging amount. Knowing this, and knowing that on day 8, she had 2400, we simply just add 2400 to 8 100's:
2400 + 8*100 = 2400 + 800
Carrie initially had $3200, or Option C.
