-4z plus 3 equal is to 6 plus 2z
Answer will be 3=-2z
Answer:
Step-by-step explanation:
Let the amount donated to City Youth Fund = $x
And the amount donated to the Educational Growth Foundation = $y
Amount donated to the Educational Growth Foundation is at least four times the amount donated to City Youth Fund.
y ≥ 4x ------(1)
Total amount she can donate is up to $440
x + y ≤ 440 ------(2)
And the constraints are x ≥ 0 --------(3)
y ≥ 0 ------(4)
And solution set will be the common shaded area of both inequalities as shown in the graph attached.
(By using a graphing tool we can find the graph).
Answer:
first must times the number
Complentary angles add to 90 degrees
a and b are complentary
a+b=90
a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7
m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37
angle a measures 53 degrees
angle b measures 37 degrees
Answer:
The correct option is A.
Step-by-step explanation:
The difference between actual value and predicted value is called residual.
Formula of residual is
Where, y is observed value or actual value and is predicted value.
The value of residual is 1.4 and option A is correct.
