Answer:
y = [tex]\frac{3}{2}[/tex] x + 4
Step-by-step explanation:
Find b and substitute for y = mx + b so
1 = 3/2(-2) + b
1 = -3 + b, so b = 1+3, b=4
Put it all together y = [tex]\frac{3}{2}[/tex] x + 4

Multiply (3x-5)(x+4)
Answer:
3x^2+7x-20
Step-by-step explanation:
Answer:
expand the brackets
3x^2 + 7x -20
Step-by-step explanation:
(3x-5)(x+4)
= 3x^2 + 12x - 5x + 20

Please I need help to find the Slope so I will be able to do the next step.
Answer:
1) 1/2
2) 2/1
3) -1/2
4) -2/1
Step-by-step explanation:
use two ordered pairs to find slope by using this formula:
difference of y-values over difference of x-values
example: for problem #1, I used points (0,3) and (2,4)
difference of y-values: 4-3 = 1
difference of x-values: 2-0 = 2
Slope is 1/2
which equation is written in standard form ?
a. y-3 = -5(x+2)
b. y= 1/2x + 2
c. 3x + 2 = y
d. -7x + 2y = 9
B is standard form. y=1/2x + 2
Answer:
d.-7x+2y=9 that is the answer
Find the area using sine rules.
Answer:
22.44 mi²Step-by-step explanation:
Step 1
Find the missing angle:
m∠H = 180° - (47° + 99°) = 34°Step 2
Find the missing sides by using the law of sines:
sin 34° / 5.9 = sin 47° / HP = sin 99° / HKHP = 5.9 sin 47°/sin 34° = 7.7 miHK = 5.9 sin 99° / sin 34° = 10.4 miStep 3
Use Heron's formula for the area:
A = [tex]\sqrt{s(s - a)(s - b)(s - c)}[/tex], where s is semi-perimeter, and a, b, c - sidesFind s:
s = 1/2(5.9 + 7.7 + 10.4) = 12Find A:
A = [tex]\sqrt{12(12 - 5.9)(12 - 7.7)( 12 - 10.4)}[/tex] = 22.44 mi²The Great Pyramid of Cheops is a square-based pyramid. The base has sides of 230m, and a height of 147m.

A story owner wants to prepare 100 lb of a candy mix that she will she for $1.36 per lb. She mixes 20 lb of jelly beans that cost 20 cents per lb with sugar candies. How much does 1 lb of sugar candies cost?
Answer:
1.65
Step-by-step explanation:
100 pounds of the mixture = 1.36 * 100 = 136 dollars.
She uses 20 pounds of jelly beans that cost
20 * .20 = 4.00
136 - 4 = 132 dollars left for 80 pounds of sugar candies.
80 pounds = 132 pounds of sugar candies.
1 pound = x
80/1 = 132 / x Cross multiply
80x = 132
x = 132 / 80
x = 1.65 / per pound

Answer:
(5, - 2 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ) , then
R(5, 2 ) → R'(5, - 2 )
Please help.
Is algebra.
Answer:
Step-by-step explanation:
a solution is where both of the lines meet. or they have the same point on each line. so you can set the equation of each line equal to the other.
for this "solution" just look at the graph and see where the two lines meet.. and find the x coordinate of that point.
I see it meeting at x =2 get it?

The average test score for 8 students is 5 the scores for 7 of the 8 students are shown what is the score of the 8th student
Answer:
70
Step-by-step explanation
Find the diagram attached
Average = Sum of scores/sample size
Given the 7 numbers
20, 20, 20, 30, 80, 80, 80
Average = 50
5 = 20+20+20+30+80+80+80+x/8
x is the score of the 8th student
50 = 330+x/8
400 = 330+x
x = 400-330
x = 70
Hence the score of the 8th student is 70
Harpo, Groucho, Chico, Zeppo, Gummo, Karl, and Skid have won three tickets to the opera. They will randomly choose three people from their group to attend the opera. How many outcomes are possible?
Answer:
35
Step-by-step explanation:
This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.
C(n,r)=C(7,3)
=7!(3!(7−3)!)
=7!3!×4!
= 35
Finally, we can see that the total number of possible outcomes is 35

Alice has taken a job with a starting salary of $17,600 and the annual raise of $850. What will her salary be on the 5th year of her job?
Answer:
21,850
Step-by-step explanation:
850 x 5 = 4,250
17,600 + 4250 = 21,850
Answer number 1 plsssss
Answer:
At Z-Mart, after the discount it is 7/8 of the original price of 225,
at ABC Sports the final price is 200,
and at Bike World, after the discount it is 3/4 of the original price of 265
so
we multiply 225 by 7/8 to get 196.88,
which is lower than ABC Sports,
and then we multiply 265 by 3/4 to get 198.75, which is higher than Z-Mart
so Z-Mart or A) is correct.
Hope this helps! :D
