just a little confused , please help me :)
Answer:
a) (x + 8) (x + 2)
b) (x + 4) (x + 3)
c) (x + 12) (x + 1)
Step-by-step explanation:
First find the multiples of coefficients of a and c (ax² + bx + c)
Then rearrange it to make it add/subtract to make the number in the middle (b in bx).
a). Look at the multiples of 16.
4 x 4 .... 4 + 4 ≠ 10
8 x 2 .... 8 + 2 = 10
1 x 16 .... 1 + 16 ≠ 10
The factors of 16 that add up to 10 are 8 and 2.
Hence we write it like (x + 8) (x + 2), and to check this you can expand it.
Same goes for b and c
b). Multiples of 12 that add up to 7 are 3 x 4 ===> (x + 3) (x + 4)
c). Multiples of 12 that add up to 13 are 1 x 12 ===> (x + 12) (x + 1)
The equation y=5+0.5x represents the cost of getting a car wash and using the vacuum for x minutes. What is the y-intercept?
Answer:
The y intercept is 5. Usually, this is the number that is by itself with no variable by it. Ex: y= 5x + 4. 4 would be the y intercept.

these angles are equal to 115°
Step-by-step explanation:
57x+1=56x+3
57x-56x=3-1
x=2
57x+1=57*2+1=114+1=115°
56x+3=56*2+3=112+3=115°

Answer:
1. C' ( -12, 1 )
B' ( -7, -2 )
2.
Original Coordinates = R ( -8, 4 )
O ( -2, 4 )
P ( -2 , 8 )
E ( -8, 8 )
(A) Reflected (y = x) = R ( 4, -8 )
O ( 4, -2 )
P ( 8, -2 )
E ( 8, -8 )
(B) Reflected (y = -x) = R ( -4, 8 )
(not sure if it's O ( -4, 2 )
supposed to be after P ( -8, 2 )
previous reflection) E ( -8, 8 )
Step-by-step explanation:
1. C ( -6, 2 ) → ( -6 - 6, 2 -1 ) → ( -12, 1 )
B ( -1, -1 ) → ( -1 - 6, -1 - 1 ) → ( -7, -2 )
2. Reflecting over y = x line --- ( x, y ) → ( y, x )
Reflecting over y = -x line --- ( x, y ) → ( -y, -x )
one side of an equilateral triangle is 12cm. find its area
What is the equation of this line in slope-intercept form to 2x+y=−19
Answer:
y = -2x - 19
Step-by-step explanation:
Slope-intercept form: y = mx + b
2x + y = -19
Subtract 2x from both sides;
y = -2x - 19

Describe two reasons to use the Internet responsibly Explain what might happen if the Internet use policies were broken at your school
Answer:
1- Using the internet responsibly can help you prepare for the future, when you are in college and are working hard to save money. 2-Internet usage abilities are granted to you to help you learn easier, do not abuse those privileges or they can and will be taken away.
If in my school the internet use policies were broken, any kid can access restricted sites and potentially can get an undesired virus or malware. ... It would be dangerous to give away any personal information on the internet because someone could attempt to find you, your family, your friends, your co-workers, etc.

Consider a diving board that is 10 feet above a pool. If the ladder is 5 feet away from the base of the diving board, approximately how tall is the ladder? A.9 ,B.11 ,C.15 ,D.17
Answer: 15 feet
Step-by-step explanation:
From the question, we are informed that a diving board is 10 feet above a pool. Since the ladder is 5 feet away from the base of the diving board, to calculate how tall is the ladder is, we subtract -5 from 10. This will be:
= 10 - (-5)
= 10 + 5
= 15 feet
The answer is option C.

10x + 5x – 3 = 2(2x – 1)
Answer:
The answer is x = 1/11
Step-by-step explanation:
hope this helps
10x + 5x – 3 = 2(2x – 1)
10x+5x-3=4x-2
15x-4x=-2+3
11x=1
To find x divide both sides by 11
11x/11=1/11
x= 1/11
[tex]\frac{1}{11} or 0.0909090909090[/tex]
Step-by-step explanation:Add similar elements: 15x-3=2(2x-1)
Expand 2(2x-1): 4x-2
Add 3 to both sides
Simplify 15x=4x+1
Subtract 4x from both sides
Simplify 11x=1
Divide both sides by 11
Simplify [tex]\frac{1}{11} or 0.0909090909090[/tex]

The table represents an inverse variation. What is the value of p?
Answer: 1.5
I have to have 20 characters but hope this helps :)
Value of [tex]p[/tex] is [tex]\frac{3}{2}[/tex]
In inverse variation, as one number increases, the other decreases and as one number decreases, the other increases.
That is [tex]xy=k[/tex] where [tex]k[/tex] is a constant.
Put values of [tex]x,y[/tex] as [tex]3,5[/tex] respectively.
[tex]3(5)=k[/tex]
[tex]15=k[/tex]
So, [tex]xy=15[/tex]
Now put values of [tex]x,y[/tex] as [tex]10,p[/tex] respectively.
[tex]10p=15[/tex]
[tex]p=\frac{15}{10}[/tex]
[tex]=\frac{3}{2}[/tex]
