y = 10x + 2 ← substitute x = 4
y = 10(4) + 2 = 40 + 2 = 42
Answer:
=42
Step-by-step explanation:

The population of a town is 132,00. The population increases 4% a year. What will be the population in 8 years?
9514 1404 393
Answer:
180,651
Step-by-step explanation:
Each year, the population is multiplied by the factor 1 + 4% = 1.04. After 8 years, it will have been multiplied by that factor 8 times. We indicate repeated multiplication like that using an exponent.
population in 8 years = 132,000 × 1.04^8 ≈ 180,651

An arithmetic sequence has this recursive formula:
a1=9
an=an-1 -3
What is the explicit formula for this sequence?
A. an=9+(n-1)(-3)
B. an=-3+(n-1)9
C. an=9+(n-3)(-1)
D. an=-1+(n-9)(-3)
Answer:
The correct answer is:
Option A. a_n=9+(n-1)(-3)
Step-by-step explanation:
Given that
a1 = 9
[tex]a_n = a_{n-1}-3[/tex]
We can see that in recursive formula the next term is being obtained by subtracting 3 from previous term
That means that the common difference is -3
We also know the first term
The general form of explicit formula for an arithmetic sequence is:
[tex]a_n = a_1 + (n-1)(d)[/tex]
We know that a1 = 9 and d = -3
Putting the values we get
[tex]a_n = 9+(n-1)(-3)[/tex]
Hence the correct answer is:
Option A. a_n=9+(n-1)(-3)

what does the a in y=a(1+r)x represent?
Answer:
The function is of the form y = a(1 − r)t, where 1 − r < 1, so it represents exponential decay. Use the decay factor 1 − r to find the rate of decay. Write an equation. Solve for r.
The "a" in the expression y = a (1+r)ˣ represents the initial amount.
What is the expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.
Given, a exponential expression y = a (1+r)ˣ
The exponential growth can alternatively be calculated using the formula f(x) = a(1 + r)ˣ, where the function is denoted by the f(x) term. The initial value of your data is represented by the variable. The growth rate is represented by the r variable.
Therefore, the initial amount is been represented by "a" in the given expression.

The triangles are congruent. Find the measure of x.
Match up the sides for each triangle using the little marks through the sides
1 to 1, 2 to 2 and 3 to 3
When you do this you see that x corresponds to c on the first triangle.
The 3 angles in a triangle = 180.
Find c by subtracting A and B from 180
C = 180- 29-63 = 88
Now x = c so x = 88
The answer is C. 88

write the linear equation given :
1. slope = 1/4; y-intercept =7
2. slope = -3; y-intercept = 2/3
3. slope = 2/3; y-intercept = 2/3
4. slope = -2; y-intercept = -1/2
5. slope = -3/4; y-intercept = -3
Answer:
1. y =1/4x + 7
2.y =-3x + 2/3
3. y =2/3x + 2/3
4.y =-2x - 1/2
5.y =-3/4x -3
Step-by-step explanation:
By using the slope- intercept form of the equation, y=mx + b, where m=slope and b=y-intercept, you can substitute the values of slope and the y-intercepts into the formula y=mx + b

Solve the equation below for x in terms of a 4(ax+3)-3ax=25+3a
Answer:
x = (13 + 3a) / a
Step-by-step explanation:
Given equation:
4(ax+3) - 3ax = 25 + 3a
Open parenthesis
4ax + 12 - 3ax = 25 + 3a
Collect like terms
4ax - 3ax = 25 + 3a - 12
Simplify
ax = 13 + 3a
x = (13 + 3a) / a
4(ax+3) - 3ax = 25 + 3a is equivalent to x = (13 + 3a) / a
