Answer:
A: [tex]y=3x+12[/tex]
Step-by-step explanation:
To start we need to know what makes lines perpendicular. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.
Then, we need to understand the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. We also know that [tex]x[/tex] and [tex]y[/tex] represent points on the line.
Now, since our equation is already in the correct form, we can start with finding the opposite reciprocal of the slope. To do this, all we have to do is flip the fraction upside down and multiply by -1. This means that the opposite reciprocal of [tex]-\frac{1}{3}[/tex] would be [tex]\frac{3}{1}[/tex] which can be written as [tex]3[/tex].
Now, since we have a list of options and only one has the correct slope, we can safely choose option A.
Angelina received two discounts on a $50 pair of shoes. The discounts were taken off one after the other. Her first coupon was 20%. If she paid $30 for the shoes, what was the dollar amount taken off for the first coupon? She received a $____ discount with the first coupon.
Answer:
$10
Step-by-step explanation:
Because 20% of 50 is 10 so 50-10=40 then 40-30=10

An arithmetic series contains 14 numbers. The first number is 12. The last number is 38. What is the sum of the series?
A. 312
B. 350
C. 494
D. 700
Answer:
B. 350
Step-by-step explanation:
done on edge
The sum of the sequence is 350 if the arithmetic series contains 14 numbers. The first number is 12. The last number is 38 option (B) is correct.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
An arithmetic series contains 14 numbers.
The first number is 12.
The last number is 38.
As we know, the sum of the arithmetic sequence or series is given by:
S = (n/2)(a + l)
Here, S is the sum of the AP
n is the number of terms
a is the first term
l is the last term
n = 14
a = 12
l = 38
S = (14/2)(12 + 38)
S = (7)(50)
S = 350
Thus, the sum of the sequence is 350 if the arithmetic series contains 14 numbers. The first number is 12. The last number is 38 option (B) is correct.

I really need help with this one
Answer:
28
Step-by-step explanation:
Since B is the midpoint of AC, that means AB = BC. That means 3x+4 = 5x-6. We can now set up an equation to solve for x:
3x+4 = 5x-6
3x+10 = 5x
10 = 2x
x = 5
Now that we know what x is, we can just plug x into the expression of AB and multiply it by 2:
(3*(5)+4)*2
=(15+4)*2
=19*2
=28
(side note: we could have plugged x into the expression of BC as well, but in this case plugging it into AB tends to be easier to solve)
Therefore, the length of AC is 28.
If b= 40 degrees and c= 30 degrees, what is the measure of d?
Answer:
It would be D. 110 degrees
Step-by-step explanation:
A triangle is always equal to 180 degrees. So, if you add b + c, you get 70 degrees. Subtract that from 180, and you get 110. Hope this helped!
Answer:
a = 110 degree
d= 70 degree
Step-by-step explanation:
a+b+c = 180. (being sum of all interior angle of a triangle is 180 degree)
a+40+30 = 180
a=180-70
a = 110
Similarly,
a+d=180. (being supplementary angle)
110+d=180
d= 70
i need help with this equation can someone please help me
Answer:
d= 24
Step-by-step explanation:
-2= d/3 - 10
-6= d-30
-d=-30+6
-d= -24
d= 24
Max Quimby picks Raspberries for his grandmother every Tuesday during 2 points
the summer. She pays him $0.75 per quart. If he were able to pick 93
quarts how much he be paid?
Answer:
Would be paid $69.75
Step-by-step explanation:
Since he is paid $0.75 per quart, and he has picked up 93 quarts, you would multiply 0.75 by 93. Which would give you $69.75.
Which equation fits the situation? Mikes test score was 20 points lower than marks if mark scored a 95 on the test which equation would give mike’s score
Answer:
95 - 20 = t
Step-by-step explanation:
Let's start with the facts. You know that Mike's test score is 20 points lower than Mark's. You know that Mark's score was 95.
If we are trying to find Mike's test score, t, the equation would be this:
The equation would be 95 - 20 = t

Rewrite the expression in the form 3^n.
Explanation:
Cross off four copies of '3' in both the numerator and denominator. Each pair cancels because 3/3 = 1, and 1 times any number is the same number. See the diagram below.
The numerator will be left with two copies of '3'. The denominator won't have anything left.
So we have 3*3 = 3^2

Step-by-step explanation:
A game store charges a monthly membership fee of $7.50, but then the charge to rent a game is only $1.00. Another store has no membership fee, but that store charges $2.00 to rent a game. How many games need to be rented each month for the total fees to be the same from either store?
Answer:
6 games.
Step-by-step explanation:
Given that,
Monthly membership fee of store 1 is $7.5, but then the charge to rent a game is only $1.00
Another store has no membership fee, but that store charges $2.00 to rent a game.
Let there be n games needed to be rented each month for the total fees to be the same from either store.
Cost of first store = $7.50+$1.00n
Cost of another store = $2.00
If cost equals,
$7.50+$1.00n=$2
n=5.5 [tex]\approx[/tex] 6
Hence, 6 games needed to be rented each month.
Your friend spent $7 in two days on lunch. He says that

How do you know whether two quantities x and y are proportional? Every ratio yx for related pairs of x and y is equivalent. Every sum x + y is the same for related pairs of x and y. Every x term is a multiple of the previous term. Every difference x – y is the same for related pairs of x and
Answer:
Two quantities x and y are said to be proportional if ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation:
Two quantities x and y are said to be proportional if ratio [tex]yx[/tex] for related pairs of [tex]x[/tex] and y is equivalent.
The symbol ∝ is used to denote the proportionality. For example, if [tex]x[/tex] is proportional to y, then it is represented as [tex]x[/tex]∝y and if [tex]x[/tex] is inversely proportional to y, then it is represented as [tex]x[/tex] ∝ 1/y
