Answer:
for 4x = 20 you have to use the division property of equality divide 20 by 4
for x - 11 = 9 you have to use the addition property of equality add 9 to 11
for 5x + 6x = 22 you have to combine like terms add 5x and 6x to make 11x
for 5(x – 2) = 30 you have to use the distributive property multiply 5 and x; 5 and -2
4x = 20; x = 5
x - 11 = 9; x = 20
5x + 6x = 22; 11x = 22; x = 2
5(x – 2) = 30; 5x - 10 = 30; x = 8

The domain is the range of values that the function expands over.For example x^2 has a domain of all real values on the ordinary number line.Recognize that 4/x is simply a modification of 1/x.Hence the graph looks like two parabolic motions on the x-y plane So the domain is [tex]( - \infty, 0) U(0 ,\infty )[/tex]Note that X cannot equal 0.Hope this helps!

Which function represents f(t) , the amount of money in the account after years a f(t) = 500 * (0.035) ^ t c. F(t) = 500 + 0.035t f(t) = 500 * (1.035) ^ t d. F(t) = 500 + 1.035t
Answer:
f(t) = 500 * (1.035) ^ t
Step-by-step explanation:
A = p(1 + r/n)^nt
Where
A = future value = ?
P = principal = $500
r = interest rate = 3.5% = 0.035
n = number of periods = 1
t = number of years = t
A = p(1 + r/n)^nt
= 500(1 + 0.035/1)^1*t
= 500(1 + 0.035) ^t
= 500( 1.035)^t
= 500 * (1.035)^t
f(t) = 500 * (1.035) ^ t

The regular price for Super Fly Sneakers at Shoes R' Us is $100. The shoes are on sale for 35% off the regular price. Jazmine uses a coupon for an additional 25% off the sale price. How much will Jazmine pay for her Super Fly Sneakers after both discounts
Answer:
$48.75
that is the answer
Answer:
Jazmine will pay only $40 for both discounts.
Step-by-step explanation:
First we need to add the two discounts, 35% + 25% = 60%.
Now we need to convert 60% into a decimal, which is 0.60.
Now we need to multiply the regular price, $100, by 0.60.
$0.60 × $100 = $60.
Now we subtract the discount by the amount, $100 - $60 = $40.

Equations and inequalities fall under the umbrella of algebra. Algebra is the category of math where letters, like x and y, are used to represent numbers. These letters are called variables, and the goal of equations and inequalities is to find the value of the variable. An equation is a statement that two expressions or values are equal, shown by an equal sign, which looks like this: =. An inequality is a statement that two expressions or values are not equal, shown by an inequality sign. The four inequality signs look like this: > (“greater than”), 437

The displacement function of a rock thrown straight up in the air is given by f(t) = -2t2 + 15.7t meters, where t is measured in seconds. Find the total distance travelled by the rock when it reaches the ground.
Answer:
0mStep-by-step explanation:
The height of the rock as it reaches the ground is zero i.e f(t) = 0
Substitute into the function to get t first as shown;
f(t) = -2t^2 + 15.7t
0 = -2t^2 + 15.7t
2t^2 = 15.7t
2t = 15.7
t = 15.7/2
t = 7.85secs
Get the total distance travelled by substituting t = 7.85 into the modeled equation;
Recall that:
f(t) = -2t^2 + 15.7t
f(7.85) = -2(7.85)^2 + 15.7(7.85)
f(7.85) = -123.245+123.245
Hence the total distance travelled by the rock when it reaches the ground is 0m

The lines in the graph of part A don't intersect at two whole numbers on the coordinate grid. Estimate the values of the solution to the nearest one-fourth of a unit. Then substitute the x- and y-values of the approximate solution into the two equations. How close do you get to the constant numbers in each equation?
Answer:
The solution lies at approximately (4.25,6.5).
Step-by-step explanation:
The estimate is pretty close for both equations. For the first equation, the estimate results in a value that is only 0.2125 units away from the constant. For the second equation, the estimate results in a value that is only 0.25 units away from the constant.

If f(x) = -4x + 3 and g(x) = 3x^2 + 2x - 4 find (f+g) (x)
Answer:
3x^2-2x-1
Step-by-step explanation:
Here, we want to find (f + g)(x)
Mathematically, that will be f(x) + g(x)
= -4x + 3 + 3x^2 + 2x -4
= -2x-1 + 3x^2
= 3x^2-2x-1
