Answer:
x= -2 y= -1
Step-by-step explanation:
stack the 2 equations on top of each other and add them together
the 2x and -2x cancel out and you are left with -9y=9
this gives you y= -1
you plug the y value into one of the equations:
2x - (-1) = -3
2x+1 = -3
2x= -4
x= -2

factor 4x^2-9x-9 and show work.
please explain the steps taken
Answer:
22x2 - 9x) - 9
Trying to factor by splitting the middle term
Factoring 4x2-9x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -9 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -12 and 3
4x2 - 12x + 3x - 9
Step-4 : Add up the first 2 terms, pulling out like factors :
4x • (x-3)
Add up the last 2 terms, pulling out common factors :
3 • (x-3)
Step-5 : Add up the four terms of step 4 :
(4x+3) • (x-3)
Hope this helps!

11b+6 >/=14b+3
please help
Answer:
Solving the inequality [tex]11b+6 >=14b+3[/tex] we get b <= 1
Step-by-step explanation:
We need to solve the inequality [tex]11b+6 >=14b+3[/tex]
solving the inequality:
[tex]11b+6 >=14b+3[/tex]
Subtracting 6 on both sides
[tex]11b+6-6 >=14b+3-6\\11b >= 14b-3[/tex]
subtracting 14 b on both sides
[tex]11b-14b >= 14b-3-14b\\-3b >= -3[/tex]
Divide both sides by -3 and the inequality will be changed to less than equal i.e <=
[tex]\frac{-3b}{-3}<=\frac{-3}{-3}\\b<=1[/tex]
So, solving the inequality [tex]11b+6 >=14b+3[/tex] we get b <= 1

Steph Curry made 12 more than twice as many shots as Lebron James in last week's game. If Steph Curry made 48 shots, what equation can you use to find out how many shots did Lebron James make?
A) 12+2x=48
B) 2-12x=48
C) 48-12x=2
D) 48x+12=2
Answer:
A) 12+2x=48
Step-by-step explanation:
Let's start by breaking down the language used here.
12 more than twice a number.
In math, more than indicates addition.
"Twice a number" means 2 times a certain number, which we will symbolize using 'x'.
So now we have:
12+2x, which in this case, equals 48.

Answer:
a) 6x³ − 5x² − 39x + 35
b) no
Step-by-step explanation:
(2x^3 − 5) (3x² + 5x − 7)
Distribute:
3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)
Distribute again:
6x³ − 15x² + 10x² − 25x − 14x + 35
Combine like terms:
6x³ − 5x² − 39x + 35
5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).

60% of the 50 students in Jessie’s gym class are 12 years old. How many students in Jessie’s class are 12 years old?
A tape diagram. There are 60 students out of 100 that are 12 years old. There are question mark students out of 50 that are 12 years old.
What steps should you use to find 60% of 50? Check all that apply.
100 ÷ 20 = 50
100 ÷ 2 = 50
60 ÷ 2 = the number of students who are 12 years old.
60 ÷ 20 = 3 students
60 ÷ 2 = 30 students
30 of the 50 students are 12 years old.

[tex]f(x) = x + \sqrt{x + 1 \frac{x} - {1} [/tex]
Answer:
A
Step-by-step explanation:
Given
f(x) = x + [tex]\frac{\sqrt{x+1} }{x-1}[/tex]
To evaluate f(3), substitute x = 3 into f(x) , that is
f(3) = 3 + [tex]\frac{\sqrt{3+1} }{3-1}[/tex]
= 3 + [tex]\frac{\sqrt{4} }{2}[/tex]
= 3 + [tex]\frac{2}{2}[/tex]
= 3 + 1

Kim takes some furniture to a consignment store the store sells used items for 20% of the selling price the remaining percent of the selling price goes to seller Kim what percent of the selling price p is the amount the seller gets
Answer:
80%
Step-by-step explanation:
The product that is being sold, is being sold for a specific price. This price would be 100% of the money being received from selling the product. Since the store is taking a 20% fee for selling the product on behalf of Kim. Then that means that 20% is being subtracted from the total value of the product (100%) like so...
100% - 20% = p
80% = p
Therefore, that would leave Kim with 80% of the selling price as profit for herself.

Suppose y is a positive integer. If x-(-y) = z, will z be greater than, or less than x?
Answer:
It would be greater
Step-by-step explanation:
If the value of z is greater than x, then the value of the variable 'y' will be a positive integer.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equation is given below.
x - (-y) = z
Simplify the equation, then we have
x - (-y) = z
x + y = z
y = z - x
If the value of z is greater than x, then the value of the variable 'y' will be a positive integer.
