Answer:
C. 25/6 ft²
Step-by-step explanation:
Let's call the dimensions of Rectangle B x and y. Then ...
xy = 5 ft²
and
x² = 6 ft²
We want to find the value of y². Solving the first equation for y, then substituting for x², we have ...
y = (5 ft²)/x
y² = ((5 ft²)/x) = 25 ft⁴/x² = 25 ft⁴/(6 ft²)
y² = (25/6) ft² . . . . . . . matches choice C
You would substitute or plug in -5 wherever there is an x in the equation.
f(-5) = 6(-5) + 7
f(-5)= -30 + 7
f(-5) = -23

Step-by-step explanation:
Answer:
B
Step-by-step explanation:
A is wrong, it increases
C is wrong, the coefficient does not determine if it is linear (straight), the exponent does.
D is wrong, you don't need to know a point to determine if it is linear, (if you have 3 points you can though. )
Answer:
12
Step-by-step explanation:
2/3 x + x = 20
2/3 x + 3/3x = 20
5/3 x = 20 ... times 3/5 both sides
x = 12
check: 2/3 x 12 + 12 = 8 + 12 = 20
