Answer:
the answer is to this question is -25
Answer:
1) -4
2) -18
3) -25
Step-by-step explanation:
1)
-6 + -8 = -14
-14 + 10 = -4
2)
Any number multiplied by a negative number will result in a negative product.
So what I do is I multiply as if there was no negative sign: 3 × 6 = 18
Then I add the negative sign to the product: -18
3)
One way you could do this is by switching it around: 18 - -7
Which would make it: 18 + 7 = 25
Then add the negative sign: -25

find the vertexform (x)=x2-12x+36
Answer:
Vertex form pf y = x^2 + 12x + 36.
Step-by-step explanation:
y = (x + 6)^2
x-coordinate of vertex:
(x + 6) = 0--> x = - 6
y-coordinate of vertex: y = y(-6) = 36 - 72 + 36 = 0
Vertex form: y = (x + 6)^2
Answer:
2
Step-by-step explanation:
X=x 2-12x+36
X+X+12x=38
14x=38
X=38/14
X=2

It is possible for a system of linear equations to have exactly 2 solutions.
Answer:
Number of Solutions
Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.

how do i do slope-intercepts
Answer:
To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

10. In how many ways can a student select 7 out of 10 questions to work on an exam
Answer:
Step-by-step explanation:
7C10 = 10!/(7!)(10-7)!
7C10 = 10!/(7!)(3!)
7C10 = (10 x 9 x 8 x 7)/(7 x 6 x 5)(6)
7C10 = (10 x 9 x 8)/6
7C10 = 720/6
7C10 = 120

Answer:
6cd^3
Step-by-step explanation:
-48c^2d^4/-8cd
you divide the -48 by -8 and you get 6.
6c^2d^4/cd
when you divide c^2 by c, d^4 by d you get c and d^3 - this is kind of because c^2 is cxc/d^4 is dxdxdxd and when you divide it by c/d the ^ decreases.

Kieran buys a car for $8000
The following year he sells the car for $7500
Find the percentage loss.
Answer:
6.25% I think
Step-by-step explanation:
If Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.
What is percentage?A percentage is the number or ratio which is expressed as a fraction of 100.
How to calculate percentage?We have been given the buying value=$8000
Selling value=$7500
Loss=Buying value- selling value
=8000-7500
=$500
Percentage of loss=loss/ buying value*100
=500/8000*100
=6.25%
If we want to check our answer then we can multiply our percentage with the buying value.
=8000*6.25%
=500
Hence if Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.

What are Two ratios of 10/3
determine the value of x if the sequence 2x-1; 3x+1; 7x-1; is a geometric sequence
Answer:
x=0 or x=3
Step-by-step explanation:
Since it is a geometric sequence, that means term divided by previous term is the same number. Let's call that number, r.
That means we have:
(3x+1)/(2x-1)=r
(7x-1)/(3x+1)=r
Since both of the ratios are the same, then we have
(3x+1)/(2x-1)=(7x-1)/(3x+1)
Cross multiply:
(3x+1)(3x+1)=(2x-1)(7x-1)
Distribute:
9x^2+3x+3x+1=14x^2-2x-7x+1
Combine like terms:
9x^2+6x+1=14x^2-9x+1
Subtract 1 on both sides:
9x^2+6x=14x^2-9x
Subtract 14x^2 on both sides
Add 9x on both sides
-5x^2+15x=0
Factor -5x:
-5x(x-3)=0
-5x=0 when x=0 since -5(0)=0
x-3=0 when x=3 since 3-3=0

I'm 3 times younger than my mom but 3 times older than my younger brother. Mom is older than my younger brother by 40 years. how old am I?
Given:
I'm 3 times younger than my mom but 3 times older than my younger brother.
Mom is older than my younger brother by 40 years.
To find:
How old am I.
Solution:
Let x be the age of the younger brother.
I'm 3 times older than my younger brother. So, my age is 3x.
I'm 3 times younger than my mom. So, she is 3 times older than me and her are is 3(3x)=9x.
The difference between the age mother and younger brother is 40 years.
[tex]9x-x=40[/tex]
[tex]8x=40[/tex]
Divide both sides by 8.
[tex]x=\dfrac{40}{8}[/tex]
[tex]x=5[/tex]
Now,
My age [tex]=3x[/tex]
[tex]=3(5)[/tex]
[tex]=15[/tex]
Therefore, I'm 15 years old.

how many shapes of size A are in B ?
I counted 9.5
then just multiply the count * the size of A
got it?
Step-by-step explanation:
area of shape A = 3cm²
number of A shape in shape B = 9 and half
1 shape A = 3cm²
9 shape A = 3×9 = 27cm²
1 half shape A = 3 ÷ 2 = 1.5cm²
area of shape B = 27cm² + 1.5cm² = 28.5cm²
