Answer:
Yep ur correct!
Step-by-step explanation:
The first one represents the numbers decreasing by a factor of 4 and the 2nd represents it of -10. C is not geometric because it is decreasing by 2 each time in which it would be arithmethic
An expression is defined as a set of numbers, variables, and mathematical operations. The zeroes of the b(x) will be (5/4) and (-5/4).
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The solution for the expression b(x) can be written as,
b(x)=16x²-25
b(x)= (4x)² - 5²
b(x)=(4x-5)(4x+5)
The zeroes of the b(x) will be (5/4) and (-5/4).
Hence, The zeroes of the b(x) will be (5/4) and (-5/4).

Answer:
1.07 (15 + x) = 42.80
Step-by-step explanation:
Given data
CD= $15
Let the cost of the video game be x
The total cost= 15+x
Hence the equivalent expression is
1.07 (15 + x) = 42.80
open bracket
16.05+1.07x= 42.80
42.80-16.05= 1.07x
26.75=1.07x
x= 26.75/1.07
x= 25
Check
7% tax for CD
=0.07*15
=1.05
total =1.05+15
=$16.05
7% tax for Video game
=0.07* 25
=1.75
total =1.75+25
=$26.75
In all
=26.75+16.05
=$42.8
Answer:
Step-by-step explanation:
Amount of communication = original price *commission percentage
= $625*7.25
= $4,1531.25
Sales for last week = Amount of commission - Original price
= $4,1531.52 -$973.00
$3,558.25
Answer:
step 3: he should have divided both sides by -7
