Answer:
30z+13
Step-by-step explanation:
i think this is right
2(x+y)=16,
x+y=16/2=8
y=8-x
x*y=15
x(8-x)=15
8x-x^2=15
x^2-8x+15=0
x^2-3x-5x+15=0
x(x-3)-5(x-3)=0
(x-3)(x-5)=0
x=3,5
when x=3
y=8-3=5
when x=5
y=8-5=3
length=5 meters
width=3 meters.
Answer:
y = - 3x + 17
Step-by-step explanation:
Note that slope is a measure of the rate of change of a linear function.
Express the function in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (5, 2) into the partial function
2 = - 15 + c ⇒ c = 2 + 15 = 17
y = - 3x + 17 ← is the linear function
