Answer:
- 13x² + 7x + 6
Step-by-step explanation:
- 4x² + 6 - (9x² - 7x) ← distribute by - 1
= - 4x² + 6 - 9x² + 7x ← collect like terms
= - 13x² + 7x + 6
What is the slope of the line that passes through the points (3,−5) and (1,−5)? Write your answer in simplest form.
Answer:
-3 I believe is correct. Tell me if I'm wrong
Step-by-step explanation:
Who can help me with this ?
Answer:
I believe the measure of the sum of interior angles of square is 360 degrees, and we know that all the angles are equal to 3x. You'd set up the equation to look like 3x+3x+3x+3x=360
simplify that, and you get 12x=360
this means x= 30

Please help me ASAP...
=========================================================
Explanation:
Point Q is located at (0,w). We see that x = 0 and y = w.
So we'll replace x with 0 and y with w. Then we solve for w.
2x+3y = -12
2(0)+3(w) = -12
0+3w = -12
3w = -12
3w/3 = -12/3
w = -4
In the second to last step, I divided both sides by 3 to undo the multiplication of 3. Saying 3w means "3 times w".
Side note: The point Q is the y intercept as this is the location where the diagonal line 2x+3y=-12 crosses the vertical y axis.
How to solve 2(x+13)=9
Answer:
x = -17/2
Step-by-step explanation:
2(x+13)=9
2x+26=9 (multiplying 2 with both the numbers)
2x=9-26 (shifting 26 on the other side of the equation changes its sign)
2x=-17
x=-17/2 (2 is in multiplication form, so shifting on the other size changes it into division)
Answer:
2 x x + 2x13=8
or,2x+26=9
or,2x=9-26
or,2x= -17
or,x= -17/2
so, x= -8.5
help please and thank you
Answer:
x=7
Step-by-step explanation:
You know that the 17x+11 and 19x-3 are equal because they are corresponding angles. Then, you would solve it like an algebraic equation:
17x+11 = 19x-3
Move all the like terms onto one side.
14=2x
It would be easier to look at if moved the x onto the left so it would look like this:
2x = 14.
Then divide by 2 and your answer should be 7.
An equation is shown below.
3(x - 2) + 7x = {(6x - 2)

Find the distance between (1,2) and (-3,5)
Answer:
5
Step-by-step explanation:
√((5-2)^2 + (-3-1)^2) = √(9+16) = 5
Answer:
5 units
Step-by-step explanation:
To Find :-
DistanceSolution :-
Using Distance Formula ,
> d = √[ ( 1 +3)²+ ( 2-5)² ]
> d = √[ 4² + 3² ]
> d = √ [ 16 + 9 ]
> d = √25
> d = 5
The girls basketball team lost 15% of their games. If they lost 3 games, how many total games did they play?
Answer:
The girls played 20 games.
Step-by-step explanation:
To fins how many games played. Divide the percentage lost by the number of games lost. Then divide the quotient from 100% to find how many games were played.
15% ÷ 3 = 5
100% ÷ 5 = 20 games

What is the slope of a line with rise and run of 4?
Answer:
1
Step-by-step explanation:
slope is equal to "rise over run"
or = rise / run.
if you mean by
a rise and a run of 4;
rise = 4 & run = 4,
then the slope is 4 / 4 = 1.
Can someone put this in order for me? Because I'm so confused.
Answer:
Step-by-step explanation:
[tex]24a-3(2a-5)=51[/tex]
Step 1: Let's solve first so we can order it later.
[tex]24a-6a+15=51\\18a+15=51\\-15 -15\\\18a=36\\\\[/tex]
Divide 18 both sides.
[tex]a=2[/tex]
Ok so we have everything solved answer: a=2.
Now we need to order.
Step 1. Distribute 3.
Step 2. Combine like terms 24a and 6a.
Step 3. Subtract 15 from both sides.
Step 4. Divide both sides by 18.
Hope this helps :)
the cost for a company to produce x smartphones can be modeled by C(x)= 2x+35 and the company's total profit after selling x smartphones can be modeled by P(x)= -x^2+120x-435. which function below represents the company's revenue for selling smartphones? ( recall that profit equals revenue minus cost)
A) R(x)= -x^2+122x-400
B) R(x)= -x^2+118x-470
C) R(x)= -x^2+122x-470
D) R(x)= -x^2+122x+400
Answer:
D
Step-by-step explanation:
R(x) = -x^2+122x+400
Solve for x.
78
5x-1
15x-3
Answer:
x=8
Step-by-step explanation:
Angle S and R are remote interior angles which means that they would add up to equal angle RQK.
78+5x-1=15x-3
Combine like terms
77+5x=15x-3
Add 3 on both sides
80+5x=15x
Subtract 5x on both sides
80=10x
Divide 10 on both sides
x=8
Solve the following simultaneous equations by drawing graphs,
(a) x +y=7 and y=x-3
b) x + y = 8 and x=y
Answer:
a) x = 5 and y = 2
b) x = 4 and y = 4
Step-by-step explanation:
Here, we want to solve the simultaneous equations by graphing
We shall be using an external graphing tool for this
The point at which the lines intersect represent the solution to the equation
please check attachment for the plots
For the first equation, we have the solution as;
x = 5 and y = 2
