Answer: x = -8 ; y = -6
Step-by-step explanation:
1*x-2*y=4
1*x = 4 + 2*y
x = 4 + 2*y
Now you replace the value of x on the following equation:
-1*x+10*y=8
-1*(4 + 2*y) = 8
-4 - 2*y = 8
-2*y = 8+4
-2*y = 12
y = -12/2
y = -6
You replace the value of y in the previous equation:
x = 4 + 2*y
x = 4 + 2*(-6)
x = 4 - 12
x = -8
Don't listen to the guy below me haha <span> f(h) = 7.5x where you input h for x
so
f(15) = 7.5(15)
f(20) = 7.5(20)
f(25) = 7.5(25) </span>
Answer: Z= -9.5
Step-by-step explanation:
write the division as a fraction
-4.75=1/2Z
Multiply both sides of the equation by 2
-9.5=Z
then swap the sides of the equation
Z= -9.5
And if they are asking for fraction form then its either
Z= - 19/2, or Z= -9 1/2
