Answer:
[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)[/tex]
solving the expression
[tex]=-7x^0+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]
apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]
[tex]=-7+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]
[tex]=-7+5x^2-x+6+8x^2-x-3[/tex]
simplify
[tex]=13x^2-2x-4[/tex]
Therefore, the simplified form is:
[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]

Which one would be the number line ???????
Answer:
B
Step-by-step explanation:
1/2x - 2 > 0
collect like terms
1/2x > 0 + 2
1/2x > 2
Divide both sides by 1/2
x > 2 divided by 1/2
inverse of 1/2 is 2/1
x > 2 times 2/1
x > 4

Guys help me please!
Can someone tell me how to find ratios and what they are please!? Don't use the web!
Answer:
Step-by-step explanation:
Suppose you are standing on a street corner. Suppose that you are counting cars. You notice that there are only black ones and white ones. For every 3 black cars there are 4 white ones. Beginning ratios always look something like this.
Black to white = 3 to 4
This is more commonly written in two ways
Black to White = 3/4 Black:White:: 3:4So what do you notice? You should see that a ratio is a fraction.
All ratios are fractions.
Now suppose you are still on the street counting cars again. Suppose you notice that after counting 70 cars, you get
Black to White = 30:40Is that still 3/4? The answer is yes. You can multiply 3/4 by the same number on the top as you did on the bottom.That's as much as I want to give you at this time. If you want more, be sure put a comment at the end of this question. If you do it within an hour, I'll just edit the question. Otherwise, I'll use comments.

f(x) = (x + 2)2 – 16
lesser r =
greater x =
Answer:
lesser x: - 6
greater x: 2
Step-by-step explanation:
f(x) = (x + 2)² – 16
(x + 2)² – 16 = 0
(x + 2 + 4) (x + 2 - 4) = 0
(x + 6)(x - 2) = 0
roots (zero): x = -6 or x = 2

Simplify FULLY 6:1.2 *
Answer:
after full simplification u will get your ratio as
5:1
The fully simplified form of the ratio 6:1.2 is 5:1.
To simplify the ratio 6:1.2, we can divide both parts of the ratio by their greatest common divisor (GCD) to obtain the simplest form.
First, let's determine the GCD of 6 and 1.2. The GCD of 6 and 1.2 is 0.6 since 0.6 is the largest number that divides both 6 and 1.2 evenly.
Next, divide both parts of the ratio by 0.6:
6 ÷ 0.6 = 10
1.2 ÷ 0.6 = 2
Thus, the simplified ratio is 10:2.
However, we can further simplify the ratio by dividing both parts by their GCD, which is 2:
10 ÷ 2 = 5
2 ÷ 2 = 1
Therefore, the fully simplified form of the ratio 6:1.2 is 5:1.
This means that for every 5 units of the first quantity, there is 1 unit of the second quantity. Simplifying ratios allows for easier comparison and interpretation of the relationship between the two quantities.

Answer:

Step-by-step explanation:
The Pet Kennel has 12 dogs and cats for the
weekend. The number of dogs is three less than
twice the number of cats. Write a system of
equations to model this.
°{
oſ d+c= 12
Id=2e - 3
os d+c= 12
2c = d - 3
Osd+c= 12
1 c = 2d - 3
of d+c = 12
Id=3- 26
Answer:
d + c = 12
d = 2c - 3
Step-by-step explanation:
Given that :
Total number of dogs and cats = 12
Let :
Dogs = d ; Cats = c
d + c = 12
Number of dogs = 2 times the number of cats less than 3 ;
Mathematically,
d = 2c - 3
The system of equations to model the situations are,
d + c = 12 and d = 2c - 3.
What is System of Equations?System of equations are a set of two or more equations which has to be solved together, which means the solution we get after solving these equations must be satisfying for all the equations given.
System of equations will get a unique solution if the number of variables in the equation is equal to the number of equations in the system.
Let 'c' denote the number of cats and 'd' denote the number of dogs.
Total number of dogs and cats = 12
That is, d + c = 12
Number of dogs is 3 less than twice the number of cats.
So, d = 2c - 3
Hence the system of equations to model the given statements is,
d + c = 12
d = 2c - 3
