Answer: (4,-5)
Step-by-step explanation:
8y = -40
(divide by 8)
y = -5
(plug it in to one of the equations)
3x + 6*-5 = -18
3x + -30 = -18
3x = 12
x = 4

Answer:
Step-by-step explanation:
We assume the given ratios are proportional. I find it easiest to write the proportion with the unknown in the numerator.
a) dollars/ounces = x/17 = 7/20
Multiply by the inverse of the coefficient of x to solve.
x = 17(7/20) = 5.95 . . . dollars
__
b) bushels/acres = x/9.6 = 225/3
x = 9.6(225/3) = 720 . . . bushels
For what value of B is the trigonometric function considered an odd function? y=cosB(x-c)
1/4
Answer:
k=8
Step-by-step explanation:
-10=10(k-9)
Firstly to solve this question, we will have to deal with the bracket
After opening the bracket ,we can then go ahead to solve the problem
Here it's goes
-10=10k-90
To solve further,add 90 to both sides
-10+90=10k-90+90
It will be observed that 90 on the right side be eliminated
80=10k
To continue with the solution we will have to divide both sides by 10
k=8
Therefore the solution to the given question is 8
