Answer:
let x be the number of cats and y be the number of dogs:
x + y = 40
4x + 4y = 160
If you divide both sides of the second equation by 4, you will be left with:
x + y = 40
Then, subtract both equations:
x + y =40
- (x + y = 40)
0 = 0
Since you have a number = a number, there are infinite solutions.

What is the equation of the line that passes through the point (8, 4) and has a slope
of 3/2?
Answer:
y = (3/2)x - 8 slope-intercept form
3x - 2y = 16 standard form
Step-by-step explanation:
Use the point-slope form of a line to do this problem.
[tex]y - y_{1} = m(x - x_{1} )\\[/tex]
In your case [tex](x_{1} , y_{1} ) = (8, 4)[/tex]
So. y - 4 = 3/2 ( x - 8)
multiply thru by 2
2y - 8 = 3(x - 8)
2y - 8 = 3x - 24
2y = 3x - 16
y = (3/2)x - 8 slope-intercept form
3x - 2y = 16 standard form
ax^2+bx+c is the first degree polynomial of x which of these letters equal zero?
First degree polynomials means that the maximum power x is raised up to that does not have a coefficient 0 is 1. And here we have a term ax^2 which means it could not be a first degree polynomial if a has a positive or negative value. Thus, letter a in this case should be 0 in order for this to be a first degree polynomial of x.

Step-by-step explanation:
Answer: x<10
Step-by-step explanation:
2x +3y = 9
-3x +3y = -6
Rewrite the second equation:
This is to make the calculation easier. There are other ways to do this as well.
3y = 3x - 6
Substitute that into the first equation:
Since they are the same thing (=), it is possible to replace 3y.
2x + (3x - 6) = 9
Solve the equation:
2x + 3x = 9 + 6
5x = 15
x = 3
Substitute x = 3 into the first equation:
2(3) + 3y = 9
6 + 3y = 9
3y = 3
y = 1
Answer: x = 3, y = 1
Here are the first four terms in an arithmetic sequence.
1 4 7 10
Work out the 30th term in the sequence.
Answer:
88
Step By Step
Step-by-step explanation:
An arithmetic sequence is defined as
an=a+d(n-1) where an=nth term, a=initial term, n=term number, and d=common difference
For sequence 1,4,7... a=1 and d=4-1=7-4=3 so
an=1+3(n-1)
an=3n-2, so the 30th term is
an=3(30)-2
an=88

If 2.5 pounds of the candies are red, and 3.75 pounds are blue, how many pounds of candy are white? Show your work.
Answer: 2.0 pounds
Step-by-step explanation:
Total pounds of candy bought = 8.25
Candies that are red = 2.5
Candies that are blue = 3.75
Candies that are white willbthen be:
Total pounds bought - (Red + Blue)
= 8.25 - (2.5 + 3.75)
= 8.25 - 6.25
= 2.0 pounds

There are 80 people waiting to tour the science museum. The tour guide takes 4 groups of 16 people each. The remaining people will be in the last tour group. How many people are in the last tour group?
Answer:
16 people
Step-by-step explanation:
Given that :
Number of people to tour = 80
Number per group = 16
Number of groups = 4
Total number of people who make up the entire groups :
Number per group * number of groups
16 * 4 = 64
The number of people in the last tour group :
80 - 64
= 16 people

Choose the polynomial that is written in standard form.
a. x + 4x5 + 10x3
b. x4 + 4x2 + 8x
c. −9x4 + 4x6 + 10x2
d. x4 + 4x4 + x6
Answer:
b. x^4 + 4x^2 + 8x
Step-by-step explanation:
I took the test. Also the exponents need to be in descending order in order for the equation to be in standard form.
So b, starts with an exponent of 4, the decreased to just the x variable with an understood exponent.
Decreasing -> 4,2,(1)
Hope this helps :)

Step-by-step explanation:
Answer:
It might be 11 but u try ur best
in the model below what is x and how do I solve it
Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.
X=6
Step-by-step explanation:
(8x-4)+(3x+17)=(17x-23)
Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.
11x+13=17x-23
Now this is what the equation should look like after combining ur alike terms.
11x+13=17x-23
-11x. -11x.
now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.
13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.
36=6x and now u just divide the 36 by 6 and remember to always divide by the x
Now the answer is x=6
2(a-7)=a+4
15 6
PLS HELPPPPPPPPPPP
Answer:
a = 18
Step-by-step explanation:
2(a-7)=a+4
Distribute 2 into left side: 2a -14 = a + 4
subtract a from both sides 2a-a-14 = a+4-a
Simplify: a - 14 = 4
Add 14 to both sides: a - 14 + 14 = 4 +14
Simplify: a = 18
If wanted, plug a into original to double check work:
plug in: 2 (18-7) = 18+4
do parenthesis first: 2 (11) = 18+4
do multiplication : 22 = 18+4
additions: 22 =22
a = 18 is correct.
Answer:
A=18
Step-by-step explanation:
2(a-7)=a+4
2a-14=a+4
add 14 to both sides
2a=a+18
subtract a from both sides
a=18
