Answer:
h(4)=17
Step-by-step explanation:
Since we are just looking for h(4), all the other equations can be ignored. Then we replace the x in the equation with 4. Remember to do the multiplication before adding the numbers together according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
[tex]h(4)=2*2+7(4)-15\\h(4)=2*2+28-15\\h(4)=4+28-15\\h(4)= 32-15\\h(4)=17[/tex]

Explain how to find the y-intercept from the table. What is the y-intercept?
Answer:
The y-intercept of a graph is the point where the graph crosses the y-axis
Step-by-step explanation:
You can find the y-intercept by looking at the graph and seeing which point crosses the y axis.
The y-intercept is the value of the function when x is zero
Given data ,
To find the y-intercept from a table, you need to identify the point where the x-coordinate is zero. The y-coordinate of this point represents the value of the dependent variable (usually denoted as "y") when the independent variable (usually denoted as "x") is zero. The y-intercept is the point at which the graph of the function intersects or crosses the y-axis.
To find the y-intercept from a table, look for the row or entry where the x-coordinate is zero. The corresponding y-coordinate in that row or entry represents the y-intercept.
Hence , the y-intercept is the value of the function when x is zero, and it represents the point where the graph of the function intersects the y-axis.

The instructor had saved $3,500 and rents an apartment
for $275 monthly. He believes the point (6, 1850) would
be on the equation of the line. Is he correct? Explain how
to check if a point is on a line.
Step-by-step explanation:
The instructor had saved $3,500 and rents an apartment for $275 monthly. The slope-intercept form of the above scenario is :
y=-275x+3500
The instructor belives that the point (6, 1850) would be on the equation of the line. Put y = 1850 and x = 6 in the above equation. So,
1850=-275(6)+3500
1850=1850
LHS=RHS
It means that the point (6,1850) lies on the line. Hence, he was correct.
Answer:
Sample Answer: Write the equation using slope and y-intercept in slope-intercept form, y = –275x + 3500. Then, substitute the x and y values of the point into the equation, 1850 = –275(6) + 3500. Simplify to see if both sides are equivalent. Yes, the instructor is correct because both sides are equivalent.

The value of 2^-3x3^-2
Answer:
[tex]\frac{1}{72}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex] thus
[tex]2^{-3}[/tex] = [tex]\frac{1}{2^{3} }[/tex] = [tex]\frac{1}{8}[/tex]
[tex]3^{-2}[/tex] = [tex]\frac{1}{3^{2} }[/tex] = [tex]\frac{1}{9}[/tex]
Then
[tex]\frac{1}{8}[/tex] × [tex]\frac{1}{9}[/tex] = [tex]\frac{1}{72}[/tex]
Answer:
1/72.
Step-by-step explanation:
2^-3 = 1 / 2^3 = 1/8.
3^-2 = 1/3^2 = 1/9
So the answer is 1/8 * 1/9
= 1/72.
"Now that you’ve created your hypotheses, it’s time to prove them. First, look at the sum of two rational numbers. Let’s say they are two rational numbers, x and y. Because they’re rational, they can be written as a ratio of integers. Let x = a/b and y = C/D, where a, b, c, and d are integers and b and d do not equal 0. The process for finding the sum x + y in terms of a, b, c, and d is shown." Question:Based on this sum and using the closure property of integers, what conclusion can you make about the sum of two rational numbers? Explain your answer.
Answer:
hello some parts of your question is missing attached below is the missing part
answer: the sum Given it can seen that according to the closure property of Rational numbers the addition of two rational numbers will sum up to a rational number provided that the rational numbers ≠ 0 and a set of rational number is closed under the closures property rule i.e x + y = y + x
Step-by-step explanation:
using the closure property and based on the sum given :
From the sum Given it can seen that according to the closure property of Rational numbers the addition of two rational numbers will sum up to a rational number provided that the rational numbers ≠ 0 and a set of rational number is closed under the closures property rule i.e x + y = y + x

"The sum given can seen according to the closure property of rational numbers. The addition of two rational numbers will sum up to a rational number, provided that the rational numbers are ≠ 0 and a set of rational number is closed under the closures property rule, in other words: x + y = y + x."
What are the measurements???
Answer:
angle 4 is 31
angle 5 is 59.
Step-by-step explanation:
M<4 and M<5 add up to a right angle which is 90 degrees . so you put it in a equation form.
2x-5+4x-13=90
rearrange it
2x+4x-5-13=90
6x-18=90
add 18 on both sides
6x=108
divide 6 from both sides
and you get x= 18
Plug in x for angle 4 =2(18)-5 = 31
plug in x for angle 5 = 4(18)-13 = 59

Ella has a mass of 56 kg, and Tyrone has a mass of 68 kg. Ella is standing at the top of a skateboard ramp that is
1.5 meters tall. Which conclusion is best supported by the given information?
If Tyrone stands at the top of the same ramp, his potential energy will be less than Ella's
If Tyrone stands at the top of a 1 m high ramp, his potential energy will be greater than Ella's.
If Tyrone stands at the top of the same ramp, his potential energy will be the same as Ella's.
If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's.
Hey
Step-by-step explanation:
Given that,
Mass of Ella is 56 kg and mass of Tyrone is 68 kg.
Position of Ella is 1.5 m on the ramp.
Potential energy of an object is given by :
P = mgh
It is directly proportional to the position of an object.
If Tyrone stands at the top of ramp at more height than Ella, it will have more potential energy. Hence, the correct option is (d) "If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's."
Answer:
it would be d.

A suit sells for one hundred thirty-eight dollars. A store employee bought the suit, using his employee discount of forty-five percent. What was the amount of his discount?
Answer:
$62.10
Step-by-step explanation:
To calculate how much the employee's discount actually was, we just multiply the original price by the discount
Plug the prices in --> 138 x 45/100
Simplify 45/100 --> 9/20
138/1 x 9/20 = 1242/20
1242/20 = 62.1
62.1 = $62.10

Find an
equation of the line through (1,8) and parallel to y = 4x + 3.
In slope intercept form
Answer:
The answer is
[tex]y = 4x + 4[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = 4x + 3
Comparing with the general equation above
Slope = 4
Since the lines are parallel their slope are also the same
Slope of parallel line = 4
The equation of the line using point (1,8) and slope 4 is
[tex] y - 8 = 4(x - 1) \\ y - 8 = 4x - 4 \\ y = 4x - 4 + 8[/tex]
We have the final answer as
[tex]y = 4x + 4[/tex]
Hope this helps you
