Answer:
−5c5−15a−25b+10
Step-by-step explanation:
13+2−5−15a−25b−5c5
=13+2+−5+−15a+−25b+−5c5
Combine Like Terms:
=13+2+−5+−15a+−25b+−5c5
=(−5c5)+(−15a)+(−25b)+(13+2+−5)
=−5c5+−15a+−25b+10
Answer:
=−5c5−15a−25b+10
The answer would be (3x+4)(2x-5) because you would factor by grouping.
Answer: Because the a-value is negative.
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- "a" is the vertical stretch
- -a is a reflection over the x-axis
- h is the horizontal shift (positive = right, negative = left)
- k is the vertical shift (positive = up, negative = down)
Given: g(x) = - (x + 1)² - 3
↓
a= -1
Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).

Answer:
$3000
$1000
Step-by-step explanation:
the formula for simple interest = principal x time x interest rate
let the amount invested in the 2% investment be a
let the amount invested in the 3% investment be (4000 - a)
(a x 0.02 x 1) + ([4000 - a] x 0.03 x 1) = $90
0.02a + 120 - 0.03a = 90
Collect like terms and solve for a
0.01a = 30
a = $3000
The amount invested in the 3% investment be (4000 - a) = $4000 - $3000 = $1000
