Answer:
hiiii
Step-by-step explanation:
but u have posted all the pictures upside down so can't understand anything
25x^2 = 16
divide each side by 25
x^2 = 16/25
take the square root of each side
sqrt (x^2) = +- sqrt(16/25)
x = +- sqrt(16)/sqrt(25)
x = +- 4/5
x = 4/5, - 4/5
Well the cost of the apples can be found by dividing the price by the amount bought. ($5/4 or $10/8 = $1.25/lb). If you want to find the amount for 6 pounds just multiply it by the individual cost (6x$1.25= $7.50)
Answer:
Expressions for y:
1. A - 3B
3. A/3 - B
3. (27/13, -60/13)
Step-by-step explanation:
Expressions for y:
A - 3B
A/3 - B
Find combinations to eliminate x
A) 8x + y = 12
B) 2x - 3y = 18
Expressions for y:
A - 3B
A/3 - B
y = 12 - 8x
2x - 3(12 - 8x) = 18
2x + 24x - 36 = 18
26x = 54
x = 54/26 = 27/13
y = 12 - 8(27/13) = -60/13
F(x)= 5(-x^3)-3+2
f(x)=5(-x^3)-1
