Problem 1 :
Given: HJ= 4x + 9, JK = 30 + 3, and KH = 33 Find: x, HJ, and JK
Answer:
Step-by-step explanation:
4x + 9 + 3x + 3 = 33
7x + 12 = 33
7x = 21
x = 3
HJ= 4(3) + 9 = 12 + 9 = 21
JK= 3(3) + 3 = 9 + 3 = 12
Sam wanted to find the difference 10 -(-6).
He said he would add the opposite. This is what he did:
10 - (-6) = 10 + (-6) = 4
Was Sam's thinking correct? Explain. In your explanation, describe how to add the
opposite and use a number line to find the value of 10 -(-6).
Given:
The expression is [tex]10 - (-6)[/tex].
Sam's calculation is [tex]10 - (-6) = 10 + (-6) = 4[/tex]
To find:
Whether Sam's thinking correct or not.
Solution:
We have,
[tex]10 - (-6) = 10+6[/tex] [tex][\because (-)(-)=(+)][/tex]
[tex]10 - (-6) = 16[/tex]
[tex]10 - (-6) \neq 4[/tex]
Therefore, Sam's thinking was incorrect.
On number first we have to move 10 units from 0 in positive direction after that negative sign means move in left direction.

2. Toby Vail.
Annual gross pay of $18,200.
Personal exemptions of $1,500.
State tax on first $3,000: 1.5 percent.
Tax on amount over $3,000:
3 percent.
Answer:
Toby Vail wis taxed for $456
Step-by-step explanation:
First, we make the deductions:
gross pay 18,200 - 1,500 deductions = 16,700 taxable income
Now, we make the tax-calculations:
first $3,000 x 0.015 = $ 45
above:
(16,700 - 3,000) x 0.03 = $411
Total tax levied from the State: $45 + $411 = $456
Notice how the tax is calcualte in brackets to solve for the different taxation rate at different income levels.

explain how to use a graph of the function f(x) to find f(3)
Answer:
Just find the coordinate at the point where the x-coordinate is 3
Step-by-step explanation:
F(x) is just another term for Y. The variable of X is the value that you input into the f(x), which just stands for a function. Since the value that they asked for was 3, you know that they inputted the value of 3 as x. Just look where the coordinate at the point where the x-coordinate is 3 to find the answer.
Answer:
Sample Response: For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.

If y varies directly as x, and y is 400 when x is r and y is r when x is 4, what is the numeric constant of variation in this
relation?
10
40
100
198
Answer:
10
Step-by-step explanation:
If there is a direct relation between two variables x and y then it can be represented as
y = kx ,
where y is dependent variable
x is independent variable
k is constant of variation
_____________________________
First condition
y = 400
x = r
using y = kx then relationship will be
400 = kr
finding k here
k = 400/r
Second condition
y = r
x = 4
using y = kx then relationship will be
r = 4k
finding k
k = r/4
since in both condition equation is same
thus, value of k will also be same
thus,
400/r = r/4
=> 400*4 = r*r
=> 1600 = r^2
[tex]\sqrt{r^{2} } = \sqrt{1600} \\r = 40[/tex]
Thus, 40 is the value of r
k = r/4 = 40/4 = 10
Thus, constant of variation is 10 which is correct choice.
To cross validate
k = 400/r = 400/40 = 10
Answer:
40
Step-by-step explanation:
[tex]\frac{r}{400}[/tex] = [tex]\frac{4}{r}[/tex]
cross multiply - 400*4 = 1600 and r*r = r^2
square both - √1600 = 40

What is the value of the expression below when z = 7 and w=10?
7z +10w
Answer:
149
Step-by-step explanation:
z = 7 and w = 10
Equation:
7z + 10w
Substitution:
49 + 100
Answer:
149
Hope this helps :)
The required value of the given expression at z = 7 and w = 10 is given as 179.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Given expression,
z = 7 and w = 10
Now put these values in the given expression,
= 7z + 10w
= 7 × 7 + 10 × 10
= 49 + 100
= 149

When a number is doubled and then added to 24,the result is 49
Answer:
Algebraic equation ; 2x+24 =49
x = 12.5
Step-by-step explanation:
Let the unknown number be x
[tex]2(x) +24 =49\\\\2x +24 =49[/tex]
Collect like terms and simplify
[tex]2x =49-24\\2x =25\\[/tex]

Mike Is standing on a ladder that is partly in a hole he starts out on a rung that 6 feet underground climbs up 14 feet the climbs down 11 feet what is mikes final position relative to the ground level
Answer:
-3
mike's final position relative to the ground is 3 feet's underground
Step-by-step explanation:
We take positive value when he is above the ground and then take negative value when he is below or underground
6 feet's underground = -6
He climbs up 14 feet = +14
He climbs down 11 feet = -11
We are required to find his last position relative to ground level
= -6+14-11
= (-6) + (-11) + 14
= -17 + 14
= -3
So we have it that mike's final position relative to the ground is 3 feet's underground
