Tran earns $16 per hour and is paid a flat fee of $46 each week. At
the end of the week her total salary can be represented by the
equation y=16x + 46, where x is the number of hours, and y is the
total weekly salary. Write this relationship in functional notation, as a
function S(h), where S(h) represents the salary for h number of hours.
Answers
Answer:
[tex]S(h)=16h+46[/tex]
Step-by-step explanation:
We just need to substitute the variables here! You already have the equations so instead of [tex]x[/tex] for hours, we use [tex]h.[/tex] And since it's a function the result is not [tex]y[/tex] but rather [tex]S(h)[/tex].
So we get the answer of: [tex]S(h)=16h+46[/tex]

The vertex of the given quadratic function is (-3, 0).
What is vertex form of a quadratic equation?The vertex form of a quadratic equation or function is [tex]f(x)=a(x-h)^{2} +k[/tex].
Where,
(h, k ) is the vertex
And, a is constant.
According to the given question
We have a quadratic function
[tex]f(x) = x^{2} + 6x + 9[/tex]
The above function can be written as
[tex]f(x) = x^{2} +2(3x) +9[/tex]
⇒[tex]f(x) = x^{2} + 2(3x) + (3^{2}) -(3)^{2} + 9[/tex]
⇒[tex]f(x) = (x+3)^{2} -9+9[/tex]
⇒[tex]f(x) = (x+3)^{2} + 0[/tex]
Comparing the above equation with the standard vertex form of quadratic function we get
h = -3 and k = 0
Hence, the vertex of the given quadratic function is (-3, 0).
Thus, option A is correct.

how do you combine like terms
Answers
Answer: you add them up
Step-by-step explanation:
Explanation:
Combining like terms is commonly used to solve algebraic expressions. Like terms are those species or variables that are the same in any algebraic representation.
Different mathematical operations can be performed on like species. We can add, divide, multiply, subtract, factorize, etc those terms.
Take for example;
Solve;
5x + 3 = 4x + 6
To solve this simply collect the like terms;
5x and 4x, 3 and 6 are like terms
5x - 4x = 6 - 3
x = 3
This is one way of solving problems by collecting like terms.

first round the 2 numbers by the tenths. Then round the numbers by ones(whohle number). After that, since ther are four sides we do 12.63 + 3.28 + 12.63 + 3.28 which equals to 15.91.

A. y=2x+3
B. y=12x+3
C. y=12x−3
D. y=−12x−3
Answers
To do this use the formula change in y/ change in x
So If we pick two points, say 0,-3 and -4,-5 the change in y is from -3 to -5 so it is -2 and the change in x is from 0 to -4 so is taking away 4 so the gradient is -2/-4 which is 1/2.
Then we need to work out the y intercept, c.
Substitute the gradient into y= Mx+ c to get y = 1/2 x + c. Use a point to substitute in and solve:
Eg 4, -1 —> -1 = 1/2 x 4 + c
Then -1 = 2 + c
Then -3 = c
So you get the end equation of
Y = 1/2x -3

2. One action figure sells for $3.50 How many action figures can Sergio buy for $20.00?
Answers
Answer:
He can buy 5
Step-by-step explanation:
To find the answer, you have to do divide 3.50 and 20. You get 5.714285714. You can't round up, since you are dealing with money, so round down to 5.
Hope this helps :)
Step-by-step explanation:
One action figure can be shown as x so x=$3.50.
Sergio has $20.00 so the equation is 20.00÷3.50 = number of x's Sergio can buy.
20÷3.50 =5 2.5/3.5
So x=5 2.5/3.5

the first equation would be y= 8/7 + 6/7the perpendicular slope would be -8/7and I solved for b by plugging in what I know for y=mx+bwhich is 6= -7/8(-8) + bsimplify so 6 = 7 + bsubtract 7 on both sides to get b = -1
