Answer:
x = -11
Step-by-step explanation:
9x+42=4x-13
(add 13 to both sides)
9x+55=4x
(subtract 9x from both sides)
55=-5x
(divide by -5)
-11 = x
You isolate the x term basically.
First you bring 4x from the right hand side to the left hand side and so the equation would be: 9x - 4x + 42 = -13
Then you bring 42 from the left hand side to the right hand side so the equation would look something like this: 9x - 4x = -13 - 42
Next subtract the x terms and the numbers on the right hand side too so you get: 5x = -55
Remove the coefficient from x and bring it to the right hand side with the operation as division. So you get: x = -55/5
Solve the division and you get: x = -11

Solve the equation 3x-4=8-x
Answer:
x=3
Step-by-step explanation:
3x-4=8-x(Group like terms)
3x+x=8+4(Add both sides)
4x=12(After adding you will proceed to divide both sides by 4)
x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)
What is the y-intercept of this graph?
A. 0
B. 2
C. 4
D. 8
Answer: 0
Step-by-step explanation:
The line runs through the coordinate (0,0), rather than starting at (0,2), (0,4), or (0,8).
Always remember that you read coordinates as (x,y) which..
X is how many spaces right or left
Y is how many spaces up or down.
Answer:
A. 0
Step-by-step explanation:
If you can look at the graph it crosses the y-axis exactly at the origin which is 0. This makes 0 the y-intercept because the line intercepts the y-axis at the point (0,0) making our solution A: 0

Say you are filing as a single taxpayer. You have a gross income of $61,026 and claim two exemptions. You can make a deduction of $2,871 for interest on your mortgage, a deduction of $2,376 for property tax, an adjustment of $3,206 for business losses, an adjustment of $2,575 for contributions to your retirement plan, a deduction of $2,682 for medical expenses, and an adjustment of $2,440 for business expenses. If exemptions are each worth $3,650 and the standard deduction is $5,700, what is your total taxable income?
a.
$39,805
b.
$35,526
c.
$37,576
d.
$43,276
Answer:
C
Step-by-step explanation:
took test
Will give brainliest if correct.
Answer:
The x-intercept is 4,0. The y-intercept is 0,2.
Step-by-step explanation:
when your finding an intercept you make the other intercept 0. This means the equation to find the x-intercept would look like 5x = 20. This is because they = 0, which means 10 x 0 is 0. Then you use the inverse operation so since it's 5 * x, it will be 20 ÷ 5 which is 4. Do the same thing with the y-intercept. Instead of changing the y to a 0, change the x. Using the inverse operation you get 2.
Have a nice day!

The initial value of f(x) is 0.
The range of values for f(x) is 0 ≤ f(x) ≤ 6.
*Hint: You can use a table to do this one and plug in -4, -3, -2, and -1 in for x in the rule for the function of f(x), and -4 is your initial x-value. The answer from the first line is the same answer for the other blank.

Find the hypothesis for side a 16 side b 20
I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following
a^2 + b^2 = c^2
16^2 + 20^2 = c^2
256 + 400 = c^2
656 = c^2
c^2 = 656
c = sqrt(656)
c = sqrt(16*41)
c = sqrt(16)*sqrt(41)
c = 4*sqrt(41)
The hypotenuse is exactly 4*sqrt(41) units long
This is approximately 25.612 when you use your calculator.

how do you solve 6-9(4p-3)= 2(6p+7)+3
Answer:
p= 1/3
=0.333
Step-by-step explanation:
Simplifying
6 + -9(4p + -3) = 2(6p + 7) + 3
Reorder the terms:
6 + -9(-3 + 4p) = 2(6p + 7) + 3
6 + (-3 * -9 + 4p * -9) = 2(6p + 7) + 3
6 + (27 + -36p) = 2(6p + 7) + 3
Combine like terms: 6 + 27 = 33
33 + -36p = 2(6p + 7) + 3
Reorder the terms:
33 + -36p = 2(7 + 6p) + 3
33 + -36p = (7 * 2 + 6p * 2) + 3
33 + -36p = (14 + 12p) + 3
Reorder the terms:
33 + -36p = 14 + 3 + 12p
Combine like terms: 14 + 3 = 17
33 + -36p = 17 + 12p
Solving
33 + -36p = 17 + 12p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-12p' to each side of the equation.
33 + -36p + -12p = 17 + 12p + -12p
Combine like terms: -36p + -12p = -48p
33 + -48p = 17 + 12p + -12p
Combine like terms: 12p + -12p = 0
33 + -48p = 17 + 0
33 + -48p = 17
Add '-33' to each side of the equation.
33 + -33 + -48p = 17 + -33
Combine like terms: 33 + -33 = 0
0 + -48p = 17 + -33
-48p = 17 + -33
Combine like terms: 17 + -33 = -16
-48p = -16
Divide each side by '-48'.
p = 0.3333333333
Simplifying
p = 0.3333333333
