Answer:
(3.5, 17)
Step-by-step explanation:
It would be nice to see the whole graph, so we can see where the functions cross.
Without that information, we can still eliminate unreasonable choices.
A) the quadratic at y=3.5 is well above the exponential
B) the most likely choice (3.5, 17)
C) at x=-8, the quadratic is above the exponential
D) neither graph goes anywhere near y = -8
Answer:
9.5
Step-by-step explanation:
The legs of the triangle are
3 and 9
From the Pythagorean Theorem
c² = a²+ b²
c² = 3² + 9²
c² = = 9 + 81
c² = 90
Take the square root of both sides
c = 9.4868329805
Rounded
9.5
The answer is x = 3 or x = -8.
Let's solve your equation step by step.
Step 1 - Factor left side of equation
(x - 3)(x + 8)=0
Step 2 - Set factors equal to 0.
x - 3 = 0 or x + 8 = 0
x = 3 or x = -8
Answer:
set mary is x years old, and helen is y years old.
first sentence:x=2y
second one:4(y-8)=x+4
bring x=2y in 4(y-8)=x+4
=>4y-32=2y+4
=>2y=36
=>y=18
=>x=36
mary:36
helen:18
