Answer:
x = 25
Step-by-step explanation:
4(2x - 1) = 7(x + 3)
8x - 4 = 7x + 21
8x - 7x = 21 + 4
x = 25
Answer:
The answer is kite.
Step-by-step explanation:
Well, just looking at the definition of a kite, we can see that it lines up with Mr. Tesoro's description and drawing of the quadrilateral. A kite has one right angle that meets up witht two equal lines. The opposite pair of lines, that are much longer, don't meet up to be a right angle. The definitions line up, so there's your match; the anser is kite.
Answer:
a
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [a, b ] is

Here [ a, b ] = [ 2, 6 ], thus
f(b) = f(6) = -
+ 70 = - 64 + 70 = 6
f(a) = f(2) = - 2² + 70 = - 4 + 70 = 66
average rate of change =
=
= - 15 → A
