Answer:
A, B, & D
Step-by-step explanation:
A: Linear functions are often written in point-slope form, y=mx+b.
B: The rate of change in linear functions is always a constant slope, the m value.
C: The initial value of a linear function could be zero. It depends on the line.
D: It makes sense that the graph of a linear function is a line.
E: A vertical line is not a function. You can do the vertical line test: if a vertical line were to hit more than one point at a single x-value, the line is not a function.

Answer:
x^7/y^7 (top right)
Step-by-step explanation:
Exponents are added together when multiplied, so it would equal x^7y^-7, but to get rid of the negative, the y would become the denominator in a fraction.
Answer:
x^7/y^3
Step-by-step explanation:
x^3+y^2+x^4+y^-5
re-arrange
x^4+x^3+y^-5+y^2
x^4+3+y^2-5
x^7+y^-3
let the minus(-)with the 3 be taken away
hence;
x^7/y^3
hence 3 is then possitive

One way is to divide using Synthetic division

↓ 1 0 1 0 1
--------------------------------------
1 0 1 0 1 0 ← remainder
Since remainder is 0 then (x - 1) is a factor of the polynomial
The quotient is of degree 1 less than the dividend, that is

Teri invested $2500 in an account with an interest rate of 2.75% compounded continuously. How
long will it take for Teri's account to earn $6000?
Answers
The time it will take for Teri's account to earn $6000 = 87 years
The total amount of money invested by Teri ( p) = $2500
The interest rate of the investment (r) = 2.75%
The simple interest is ( I) = $6000
Therefore the time to generate the interest of $6000
[tex] \frac{i \times 100}{p \times r \: } = t[/tex]
Therefore, time =
[tex] \frac{6000 \times 100}{2500 \times 2.75} [/tex]
[tex] \frac{600000}{6875} [/tex]
=87 years.
Therefore, the time it will take for Teri's account to earn $6000 = 87 years

3(x+2) = 2(x+5)? What does it equal?
Answers
Answer:
x=4
Step-by-step explanation:
3(x+2) = 2(x+5)
Distribute
3x+6 = 2x+10
Subtract 2x from each side
3x-2x+6 = 2x-2x+10
x +6 = 10
Subtract 6 from each side
x+6-6 = 10-6
x = 4
Answer:
x = 4
Step-by-step explanation:
Original Equation:
3(x + 2) = 2(x + 5)
Use distributive property
3 · x = 3x
3 · 2 = 6
Your equation should look like this now:
3x + 6 = 2(x + 5)
Use distributive property for the other side
2 · x = 2x
2 · 5 = 10
Your equation:
3x + 6 = 2x + 10
Subtract 6 from both sides
3x = 2x + 4
Subtract 2x from both sides
1x = 4
Divide both sides by 1
x = 4

Answer:
y - 5 = - [tex]\frac{3}{5}[/tex](x + 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Given
5x = 3y , that is
3y = 5x ( divide both sides by 3 )
y = [tex]\frac{5}{3}[/tex] x ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{3} }[/tex] = - [tex]\frac{3}{5}[/tex] and (a, b) = (- 5, 5), then
y - 5 = - [tex]\frac{3}{5}[/tex] (x - (- 5) ), that is
y - 5 = - [tex]\frac{3}{5}[/tex] (x + 5) ← equation of perpendicular line
