Answer:
1. 4(x² + 7x - 9)2. (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. 20x² - 67x + 56Step-by-step explanation:
1. factor 4x^2+28x-36
= 4x² + 28x - 36
re-write 36=4*9, and 28=4*7
= 4x² + 4 * 7x - 4 * 9
factor out common term:
= 4(x² + 7x - 9)2. factor 125x^6-27y^15
= 125x⁶ - 27y¹⁵
=(5x²)³ - (3y⁵)₃
apply difference of cubes: x³-y³ = (x-y)(x²+xy+y²)
= (5x² - 36y⁵)(5²x⁴ + 5 * 3x²y⁵ + 3²y¹⁰)
refine:
= (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. multiply (4x-7)(5x-8)
apply the FOIL method
= 4x * 5x + 4x (-8) + (-7) * 5x + (-7) (-8)
= 20x² - 67x + 56Renee is simplifying the expression (7) (13/29) (1/7).She recognizes that 7 and 1/7 are reciprocals, so she would like to find their product before she multiplies by 13/29. Which property will allow Renee to do this without changing the value of the expression

Answer:
y = x - 6y = -x + 5y = x - 5Step-by-step explanation:
Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept
1. Points are:
(2, -4) and (4, -2)Slope is:
m = (y2 - y1)/(x2 - x1) m = (-2 - (-4))/(4 - 2) = 2/2 = 1y-intercept is - 6 as per graph
Then the formula is
y = x - 62. Points are:
(0,5 ) and (4, 1)Slope is:
m = (1 - 5)/(4 - 0) = -4/4 = -1y-intercept is 5 as per point
Then the formula is
y = -x + 53. Points are:
(-3, 1), (-1, -3)Slope is
m = (3 - 1)/(-1 -(-3)) = 2/2 = 1y-intercept is -5 as per graph
Then the formula is
y = x - 5Admission to the fair costs $5.50. Each ride costs you 75 cents. You have $15 to spend at the fair including admission. Write and solve an inequality that represents the possible number of rides that you can go on. Choose the correct inequality answer.
Answer:
Step-by-step explanation:
15-5.5 is 9.5
9.5/.75
up to 12
15=.75x-5.50 (i think)
Write the standard form of the equation of the line that passes through (-2, -3) and (2, -5).
the slope is 6-2/2-(-2)=4/4=1
point slope form: y-6=1(x-2)
slope-intercept form: y=x+4
Standard form: -x+y=4 change to x-y=-4

A cylindrical tube has a length of 14.4cm and a radius of 1.5cm and is filled with a colorless gas. If the density of the gas is known to be 0.00123g/cm 3 , what is the mass of the gas in the tube in mg?
Answer:
0.125214 gStep-by-step explanation:
we know that density is given as
density=mass/volume
the volume of the cylinder
v= πr^2h
v=3.142*1.5^2*14.4
v=3.142*2.25*14.4
v=101.8cm^3
Given that density =0.00123g/cm^3
mass= density*volume
masss= 0.00123*101.8
mass= 0.125214 g
Quan makes $72 a day as an Uber driver, plus $8 for each client he has. If
Quan typically makes $104 a day. How many clients does he usually have
Answer:
Quan usually has 4 clients
Step-by-step explanation:
Working backward at math is to start with the final situation and work back one step at a time to get to the beginning.
We know Quan makes $104 a day, including his $72 fixed rate plus an $8 rate per client.
Subtracting the total and the fixed rate, we can find the variable part of his earnings.
$104 - $72 = $32
Quan usually makes $32 for the variable rate at $8 per client, thus he usually has $32 / $8 =4 clients.
Quan usually has 4 clients

4. 16
5. 300
Step-by-step explanation:
Just divide the first two numbers and then multiply the quotient by the last number. You'll be ok, you've got this, keep your head up!
1. 52/4 = 13 and 13 x 3 = 39
2. 45/9 = 5 and 5 x 3 = 15
3. 470/10 = 47 and 47 x 7 = 329
4. 10/2.5 = 4 and 4 x 4 = 16
5. 125/2.5 = 50 and 50 x 6 = 300

A concert charges $30 admission and $15 per shirt. Alyssa paid $75 at the concert for her admission and shirts. Write and solve an equation to find the number of shirts Alyssa bought. Explain what your variable represents.
Answer:
75-30/15=x
Step-by-step explanation:
75-30=45
45/15=3
75-30/15=x
Answer:
30+15(x)=75 so x would =3
Step-by-step explanation:
So you have one ticket which is $30, then you add 15 times however many shirts she buys which in total will equal $75. She would have bought 3 shirts. So 30+ 15(3)=75. Hope that helps!
