Step-by-step explanation:
To factorise a quadratic we have to go from an expression such as x2 − 2x − 15 to the linear factors (x − 5)(x + 3) which generate it when multiplied out.
(05.03 LC) The equation shows the relationship between x and y: y = 7x + 2 What is the slope of the equation? (5 points) −7 −5 2 7
Answer:
The slope of the equation is the final option listed: The slope is 7.
Step-by-step explanation:
In a y = mx + b equation, b represents the slope. So, whatever 'b' is, that's the slope. In this equation, we have y = 7x+2, so that means that the slope is 7. It also means that the y-intercept is 2. I'll attach a photo that helps!

Step-by-step explanation:
A shoe store paid the manufacturer $27.00 for a new pair of basketball shoes. If the store sells the basketball shoes for $60.75, what is the percent mark-up?
Answer
125% markup
Step-by-step explanation:
Hope this helps :)
The percentage markup the store has made is 125%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A shoe store paid the manufacturer $27.00 for a new pair of basketball shoes.
The store sells basketball shoes for $60.75.
So, Amount markup is $(60.75 - 27.00) = $33.75.
∴ The percentage markup is (33.75/27)×100%.
= 125%

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

What values of b satisfy 4(3b + 2)^2 = 64?
Answer:
The value of 0 can satisfy b.
Step-by-step explanation:
4(3b + 2)^2 = 64
(12b + 8)^2 = 64
(12b + 8)^2 = 64
144b + 64 = 64
144b + 64 - 64 = 64 - 64
144b = 0
144b / 144 = 0 / 144
b = 0
So, the value of 0 can satisfy b.
Answer:
b = [tex]\frac{2}{3}[/tex] or b = -2
Step-by-step explanation:
4(3b + 2)^2 = 64
Divide by 4 on both sides
(3b + 2)^2 = 16
Square root both sides
√(3b + 2)^2 = √16
3b + 2 = ±4
Subtract 2 on both sides
3b = ±4 - 2
Divide by 3 on both sides
b = (±4 - 2)/3
If 4 is positive, b is [tex]\frac{2}{3}[/tex]
If 4 is negative, b is -2

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.

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

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

Hello! Some assistance with this question would be really helpful (:
The mode is the most common number in the data set. If there are two numbers that appear frequently (in this case 69 and 73) then this data set has two modes.
The median is the middle of the set of numbers (line them up from top to bottom).
In this case it should look something like:
68 68 69 69 69 69 70 70 71 72 72 73 73 73 73 75 78
If the whole list of numbers are even, then pick the two middle numbers and find their average. If it is odd, just choose the middle most number.
Mean is the average of all numbers. If you have 5 numbers, add them all up and divide by 5. If you have 10 numbers, add them all up and divide by 10.
