-6p-3=9 what does p equal
Answer:
-2
Explanation:
-6 x -2 = 12
12 - 3 = 9
Answer:
p=-2
Step-by-step explanation:
Move the -3 to the other side by adding 3 on both sides:
-6p-3+3=9+3
The equation now looks like this:
-6p=12
Divide -6 on both sides:
-6p/-6=12/-6
The equation now looks like this:
p=-2 which is the answer

88 is a solution to (1/8) x =11 because if x = 88 then the equation (1/8) x = 11 is true.
Answer:
True
Step-by-step explanation:
To check to see if the statement given is true we need to substitute x with 88 and solve.
[tex](1/8)x=11[/tex]
Substitute 'x' for 88.
[tex](1/8)88=11\\\\\boxed{11=11}[/tex]
88 is a solution to the equation, therefore the statement is true.

y = 5x
y = 9x + 4
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)

Answer:
they would both be 61°
Step-by-step explanation:
when the angles make out a straight line it equals to 180 and 180 subtracted to 119 comes out to 61 and both b and c are vertical angles which would make them congruent
Answer:
B= 61 C=61
Step-by-step explanation:
You can see how there is a straight line (180 degrees) so if you do 180-119 you get 61 degrees
y - 13 = 5x
y – 5x = 12

The solution to this given system of equations is (x,y) = (0.4,15).
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
y - 13 = 5x
y - 5x = 12
Now,
To do this, we can add both equations together to eliminate x:
(y - 13) + (y - 5x) = 5x + 12 2y - 13 - 5x = 17 2y = 30 y = 15
Now that we have found y, we can substitute it into either equation to find x. For example:
15 - 13 = 5x 2 = 5x x = 0.4
Therefore, by the given system of equations the answer will be (x,y) = (0.4,15).

Identify whether the expressions are equivalent or not equivalent: 7y – 15 + 2y and 9y - 15
Answer:
Yes, the two expressions are equivalent
The given expression 7y - 15 + 2y and 9y - 15 are equivalent.
What is equivalent expression?
Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same, even they look different.
According to the given question.
We have two expressions
[tex]7y - 15 + 2y ...(i)[/tex]
And, [tex]9y - 15 ...(ii)[/tex]
The expression (i) can be written as
[tex]7y - 15 + 2y[/tex]
[tex]=(7y + 2y)-15[/tex] (adding the like terms)
[tex]= 9y -15[/tex]

Given f(x) = 2x^2+ kx – 9, and the remainder when f(x) is divided by x + 6 is
57, then what is the value of k?
Given:
The function is
[tex]f(x)=2x^2+kx-9[/tex]
The remainder when f(x) is divided by x+6 is 57.
To find:
The value of k.
Solution:
According to the remainder theorem, if a polynomial function f(x) is divided by (x-a), then f(a) is the remainder.
The remainder when f(x) is divided by x+6 is 57.
Using remainder theorem, we get f(-6)=57.
Putting x=-6 in the given function.
[tex]f(-6)=2(-6)^2+k(-6)-9[/tex]
[tex]57=2(36)-6k-9[/tex]
[tex]57=72-6k-9[/tex]
[tex]57=63-6k[/tex]
On further simplification, we get
[tex]6k=63-57[/tex]
[tex]6k=6[/tex]
[tex]k=\dfrac{6}{6}[/tex]
[tex]k=1[/tex]
Therefore, the value of k is 1.
