Use substitution to solve the system.
x = 3y +7
3x + 4y = 8
Answer:
x=4, y=-1
Step-by-step explanation:
x=3y +7. equation 1
3x+4y=8. equation 2
substitute equation 1 into equation 2
3 (3y +7)+4y =8
9y+21+4y=8
13y+ 21=8
13y=8-21
y=-13/13
y=-1
substitute the value of y into equation 1
x=3(-1)+7
x=-3+7
x=4

in Slope-Intercept form (y=mx+b)
Answer:
Slope: 3
y = 3x - 4
Step-by-step explanation:
Slope = rise/run = 3/1 = 3
y = mx + b
m = slope = 3

A toy glider plane is launched from a height of 50 feet above the ground. If the plane descends at a constant rate of 1.3 feet per second, then its height, in feet, after s seconds can be found using the equation h = 50-1.3s. Use the equation to find the height of the glider 9 seconds after it was launched.
Answer:
38.3 feet
Step-by-step explanation:
h=50-1.3(9)
h=50-11.7
h=38.3

Rewrite the equation below so that it does not have fractions.
Do not use decimals in your answer.
Answer:
x=17/14
Step-by-step explanation:
(7/9)x+2=(5/6)
18 is the least common multiple between 9 and 6, so we can multiply each fraction by 18.
7 18 126
---- * ------ = -------- = 14
9 1 9
14x+2=(5/6)
5 18 90
---- * ------ = --------- = 15
6 1 6
14x+2=15
+2 +2
14x=17
x=17/14

Complete Question
The Henderson Hawks minor-league baseball team is giving away baseballs an
game. The balls cost $3 each and the towels cost $2 each. The team wants to give away 200 items and have 500 to spend. How many of each item should the team give away Show your
work or explain your reasoning.
Answer:
They should give away 100 balls and 100 towels
Step-by-step explanation:
Let the number of balls = x
Let the number of towels = y
x + y = 200........ Equation 1
y = 200 - x
$3 × x + $2 × y = $5000
3x + 2y = 5000...... Equation 2
3x + 2(200 - x)= 5000
3x + 400 - 2x = 5000
Collect like terms
3x - 2x = 500 - 400
x = 100
Number of balls to be given away = 100
Note:
y = 200 - x
y = 200 - 100
y = 100
Number of towels to be given away = 100
Therefore, they should give away 100 balls and 100 towels

Which values from this set {−36, −32, −16, 0, 4, 16} satisfy this inequality? −14x+6≥14 −32, −16, 0, 4, and 16 only 0, 4, and 16 only −36, −32, and −16 only −36 and −32 onlyWhich values from this set {−36, −32, −16, 0, 4, 16} satisfy this inequality? −14x+6≥14 −32, −16, 0, 4, and 16 only 0, 4, and 16 only −36, −32, and −16 only −36 and −32 only
Answer:
Step-by-step explanation:
Given the inequality −14x+6≥14, we are to find the range of x that will make the inequality true.
Given −14x+6≥14
Subtract 6 from both sides.
−14x+6-6≥14-6
-14x≥8
-7x≥4
Multiply both sides by -1
-(-7)x≤-4
7x ≤ -4
x≤-4/7
This shows that the values of x is always less than or equal to -0.57
Hence the values less tan the value of x in the inequality are -36, -32 and -16
A company's stock began the day at $36.66 per share. That price drops by $1.69 each hour.
a. What is the price per share after 6 hours?
Answer:
After 6 hours the price per share is $26.52
Step-by-step explanation:
You multiply 1.69 by how many hours which in your case is 6. This gives you $10.14. Then you subtract 36.66 by 10.14 and you get your answer.

The camp athletic director wants to arrange kickball games for high school students and middle school students. Because of the ages of the campers, the high school kickball field is larger than the middle school field. The length of the square base path of the high school field is represented by the expression 2x−3 and the length of the middle school base path is represented by the expression x−8.
What is the area of the middle school field if its side measures x−8 feet?
What is the area of the high school field if its side measures 2x−3 feet?
Answer:
Step-by-step explanation:
The area of the high school field’s base path is (4x^2 -12x + 9) ft^2
The area of the middle school field’s base path is ( x^2 -16x + 64) ft^2
The difference in size between the two is
(3x^2 +4x - 55) ft^2
Step-by-step explanation:
Firstly, we are to calculate the area of the high school field’s base path
Mathematically, the area of a square is L^2
where L is the length of the side of the square. The area of the high school field base path is thus;
(2x-3) * (2x-3) = 2x(2x-3) -3(2x-3) = 4x^2 -6x -6x + 9 = (4x^2 -12x + 9) ft^2
The area of the middle school field’s base path can be calculated in a similar fashion
That would be (x-8) * (x-8) = x(x-8)-8(x-8) = x^2 -8x -8x + 64 =( x^2 -16x + 64) ft^2
The difference in size between this two will be;
(4x^2 -12x + 9) - ( x^2 -16x + 64) = 4x^2-x^2-12x+16x+9-64 = (3x^2 +4x - 55) ft^2
