How many solutions does this equation have?
-4p + 8 = -2p
no solution
one solution
infinitely many solutions
Answer:
one solution because you combine like terms and your answer is p=4
Solve for m
y= 4mx – 5
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]y = 4mx - 5[/tex]
Add sides 5
[tex]y + 5 = 4mx - 5 + 5[/tex]
[tex]y + 5 = 4mx[/tex]
[tex]y + 5 = m \times (4x)[/tex]
Divide sides 4x
[tex] \frac{y + 5}{4x} = \frac{m \times 4x}{4x} \\ [/tex]
[tex] \frac{y + 5}{4x} = m \\ [/tex]
[tex]m = \frac{y + 5}{4x} \\ [/tex]

10s - 5 = 20
Value of s
Answer:
2.5
Step-by-step explanation:
10s-5=20
(add 5 to both sides)
10s=25
(divide both sides by 10)
s=2.5
Answer:
s = 2.5
Step-by-step explanation:
you need to figure out what multiplied by 10 will give you 25, because then you have to subtract 5 in the second part of the equation to get 20.
10 multiplied by 2.5 equals 25, so s = 2.5

Line g has an equation of y = -9x - 9. Perpendicular to line g is line h, which passes
through the point (9,-5). What is the equation of line h?
Write the equation in slope-intercept form. Write the numbers in the equation as proper fractions, improper fractions, or integers.
Answer:
y=1/9x - 6
Step-by-step explanation:
perpendicular lines have slops that are the negative reciprocal of one another. After you find the slope you then plug in the point to find b using the equation: -5=1/9(9) + b .
What could be the most accurate answer for this question
Answer:
Yes (A)
Step-by-step explanation:
The right angle (90 degree angle) at H makes it a right triangle

Answer:
Yes
Step-by-step explanation:
Answer: Yes it is equivalent
Step-by-step explanation:
If you crossed out the 12 and put it under 15, it would be 15/12=1.25.
Same for the second one cross out the 4 and put it under the 5 and it would be 5/4 is 1.25.

Which equation represents a line parallel to the line shown on the graph?
y=4x-1
y=-4x+3/5
y=1/4x+5
y=-1/4x-1
Answer:
It is -1/4-1. The slope of the line is -1/4, so the only line that can be parallel is a line with the same slope.
Answer: y=1/4x-2

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)
Answer:
25811Step-by-step explanation:
We are given the rule [ f(n) = 3n - 1 ] and n represents the term.
First term:
f(n) = 3n - 1
f(1) = 3(1) - 1
f(1) = 3 - 1
f(-1) = 2
Second term:
f(n) = 3n - 1
f(2) = 3(2) - 1
f(2) = 6 - 1
f(2) = 5
Third term:
f(n) = 3n - 1
f(3) = 3(3) - 1
f(3) = 9 - 1
f(3) = 8
Fourth term:
f(n) = 3n - 1
f(4) = 3(4) - 1
f(4) = 12 - 1
f(4) = 11
As you can see, the common difference is 3.
Best of Luck!
Answer:
2,5,8,11
Step-by-step explanation:
If n=1, 3n-1 =3*1-1 =3-1 =2
If n=2, 3n-1 =3*2-1 =6-1 =5
If n=3, 3n-1 =3*3-1 =9-1 =8
If n=4, 3n-1 =3*4-1 =12-1 =11
Solve the equation: 3x − x − 5 = 2(x + 2) − 9 No solution, 1, All real numbers, 0
Answer:
I hope this helps
Step-by-step explanation:
Simplifying
3x + -1x + -5 = 2(x + 2) + -9
Reorder the terms:
-5 + 3x + -1x = 2(x + 2) + -9
Combine like terms: 3x + -1x = 2x
-5 + 2x = 2(x + 2) + -9
Reorder the terms:
-5 + 2x = 2(2 + x) + -9
-5 + 2x = (2 * 2 + x * 2) + -9
-5 + 2x = (4 + 2x) + -9
Reorder the terms:
-5 + 2x = 4 + -9 + 2x
Combine like terms: 4 + -9 = -5
-5 + 2x = -5 + 2x
Add '5' to each side of the equation.
-5 + 5 + 2x = -5 + 5 + 2x
Combine like terms: -5 + 5 = 0
0 + 2x = -5 + 5 + 2x
2x = -5 + 5 + 2x
Combine like terms: -5 + 5 = 0
2x = 0 + 2x
2x = 2x
Add '-2x' to each side of the equation.
2x + -2x = 2x + -2x
Combine like terms: 2x + -2x = 0
0 = 2x + -2x
Combine like terms: 2x + -2x = 0
0 = 0
Solving
0 = 0

If 3 tickets to a certain show cost $13.20, what would 7 tickets cost?
What is this answer?
Answer:
$ 30.8Step-by-step explanation:
ratio and proportion:
3 tickets = 7 tickets
$13.20 x
then cross multiply: 3 (x) = 13.20 (7)
simplify: 3x = 92.4
solve for x = 92.4 / 3
x = $ 30.8
therefore,
7 tickets costs $ 30.8
