Answer:
64%
Step-by-step explanation:
Find the percent change by finding the difference between the amounts, then dividing it by the original amount
(4,100 - 2,500) / 2,500
1600 / 2500
= 0.64
So, the percent change is 64%
At the beginning of a population study, city had 210,000 people. Each year since, the population has grown by 5.5%. Let t be the number of years since the start of the study. Let y  be the cities population. Write an exponential function showing the relationship between y and t. 
Y=
Answer:
y = 210,000(1.055)^t
Step-by-step explanation:
Initial population: p = 210,000
Annual growth rate: 5.5% = 0.055
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 210,000(1 + 0.055)^t
y = 210,000(1.055)^t

F(7)=?
What does f(7) equal?
Answer:
F(7) = 11
Step-by-step explanation:
F(7) = 2(7) -3
= 14 - 3
= 11
Answer:
f(7)=2/7t+-3/7
Step-by-step explanation:
you just have to plug 7 in and put an = sign which makes F(7)=2t-3 then solve
Jerry is saving his money. He started with $15.00. If he adds $10.00 to his savings
each month, how much will he have saved after 2.5 months?
Answer:
$40
Step-by-step explanation:
use y = mx + b
y = amount saved = ?
m = amount saved per week = $10
x = time (in months) saving = 2.5
b = money jerry started with = $15
plug in:
y = (10)(2.5)+15
y = $40

An 18% tip is left on a $65 dinner bill. 5% tax is added (before tip). What is the total paid?
Answer: $79.95
Step-by-step explanation:
65 × 0.18 = 11.7
65 × 0.05 = 3.25
11.7 + 3.25 = 14.95
14.95 + 65 = $79.95

2x – 3y = -5
у = х – 1
y=?
x=?
HELP
Answer:
Y = 1
X= -1
Step-by-step explanation:
Y is 3 so x is 2 and if y = x then x - 1 would be one and then that would make y = 1
X is 2 - y which is 3 will equal -1
Answer:
Step-by-step explanation:
2x – 3y = -5.........(i)
у = х – 1................(ii)
Multiply equation (ii) by 3,
3у = 3х – 3.......(iii)
Add (i) and (iii)
2x – 3y = -5
+
-3x + 3y = – 3
=
-x = -8
x = 8
put the value of x in eq (ii)
у = х – 1
у = 8 – 1
y = 7

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
What is LCM?It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
The GCF of 14x and 18xy
As we know, GCF is the greatest common factor.
The greatest common factor of 14 and 18 or
GCF(14, 18) = 2
And the greatest common factor of GCF of x and xy
= x
the greatest common factor of 14x and 18xy is:
= 2x
Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

The Henry family drove 276.5 miles on the family vacation. They used 7.9 gallons of gas. How many miles per gallon of gas did they get on the trip?
Answer:To solve this problem you would have to write 276.5 over 7.9 and divide the numerator and denominator by 7.9 since you want miles per gallon (it should have a denominator of 1 after you divide). When you do this you will get 35, so the Henry family got 35 miles per gallon of gas on the trip.

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?
Answer:
x = -4, 4
Step-by-step explanation:
Given graph in the attachment represents the function y = f(x)
Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.
Since, graph of the function touches and crosses at x = -4 and x = 4
Therefore, all real solutions of the function are x = -4 and x = 4
What is the equation of the line shown below?
A. Y=(4/5)x-1
B. Y=-(4/5)x-1
C. Y=(5/4)x-1
D. Y=-(5/4)x-1
Answer:
B
Step-by-step explanation:0
The negative in front of the -(4/5), means you have to move four spaces back but move five up
