-6x + 8y = 18
They also tell us
3x = y, which is also y = 3x (just reversed)
So we take 3x and substitute it where we see y in the first equation, then solve for x
-6x + 8(3x) = 18
-6x + 24x = 18
18x = 18
x = 1
Then we solve for y
y = 3x
y = 3(1)
y = 3

Answer:
(x, y) = (-1, -3)
Step-by-step explanation:
You notice that the coefficient of x in the first equation is double the opposite of the coefficient of x in the second equation. This means we can make the x-term disappear by adding twice the second equation to the first.
(-6x +8y) +2(3x) = (-18) +2(y)
8y = -18 +2y . . . simplify
6y = -18 . . . . . . . subtract 2y
y = -3 . . . . . . . . . divide by 6
Substituting into the second equation, we have ...
3x = -3
x = -1 . . . . . . . . . divide by 3
The solution is (x, y) = (-1, -3).

Kristin's Bikes rents bikes for $11 plus $2 per hour. Willie paid $23 to rent a bike. For how many hours did he rent the bike?
Define the variable, write an equation, and solve the equation.
Answers
Answer:
6
Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11
12 = 2x
x = 6

6x - 7y = 5
Answers
Answer:
(4,-1)
Step-by-step explanation:
x is 4 y is -1
Answer:
(2,1)
Step-by-step explanation:
Let's solve your system by elimination.
6x−7y = 5;−4x+7y=−1
6x−7y=5
−4x+7y=−1
Add these equations to eliminate y:
2x = 4
Then solve2x = 4for x:
2x = 4
(Divide both sides by 2)
x = 2
Now let's plug x in to solve for y.
6x - 7y = 5
6(2) - 7y = 5
12 - 7y = 5
subtract 12 on both sides.
-7y = -7
divide both sides by -1
y = 1

Step-by-step explanation:
For a), there is a shaded region for where 15 is, and the number line is going towards the left, so x will be less than but also equal to 15
For b), there is not a shaded region for where 16.5 is, but the number line is going towards the right, so x will be greater than 16.5
For c), there is not a shaded region for where 34.5 is, but the number line is going towards the left, so x will be less than 34.5
For d), there is not a shaded region for where 23 is, but the number line is going everywhere else so it is x =/= 23(x does not equal to 23)
A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid is What is the height of the pyramid?
Answers
Answer:
9.48
Step-by-step explanation:
Complete question
A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the pyramid?
To get the height of the pyramid, we will use pythagoras theorem.
slant height l is the hypotenuse
length of the base is the adjacent
height of the pyramid is the opposite
According to the theorem;
l² = h² + b²
90.1² = h² + 89.6²
8,118.01 = h²+8,028.16
h²= 8,118.01 - 8,028.16
h² = 89.85
h =√89.85
h = 9.48
Hence the height of the pyramid will be 9.48
Note that the value of the slant height was assumed to solve the problem.
The highest elevation in Delaware is 106 feet higher than the highest elevation in Florida. Louisiana's highest elevation is 190 feet higher than Florida's highest elevation. If you climbed from sea level to the highest points in Delaware, Florida, and Louisiana, you would only climb 1331 feet. How high is the highest elevation in each of the three states?
Answers
Answer:
Florida = 345 feets
Delaware = 451 feets
Louisiana = 535 feets
Step-by-step explanation:
Given that:
Let :
Highest elevation in Florida, = x
Highest elevation in Delaware = x + 106
Highest elevation in Louisiana = x + 190
Sum of highest elevation in the 3 states = 1331 feets
Hence,
x + x + 106 + x + 190 = 1331
3x + 296 = 1331
3x = 1331 - 296
3x = 1035 feets
x = 1035 / 3
x = 345 feets
Hence,
Highest elevation in Florida, = x = 345
Highest elevation in Delaware = 345 + 106 = 451
Highest elevation in Louisiana = 345 + 190 = 535

a metal box that is in shape of cuboid has the following dimensions. the length is 9 inches, width is 2 inches and height is 1. 5 inches. find the total cost of silver coating the entire box if the cost of coating is $2.50 per Sq. inches
Answers
Given:
Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.
The cost of silver coating is $2.50 per sq. inches.
To find:
The total cost of silver coating for the box.
Solution:
The total surface area of a cuboid is
[tex]A=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height.
Putting [tex]l=9,b=2,h=1.5[/tex], we get
[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]
[tex]A=2(18+3+13.5)[/tex]
[tex]A=2(34.5)[/tex]
[tex]A=69[/tex]
So, the total surface area of the box is 69 square inches.
Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is
[tex]Cost=69\times 2.50[/tex]
[tex]Cost=172.50[/tex]
Therefore, the cost of silver coating for the box is $172.50.

m=(5+1)/(-1-3)
m=6/(-4)
m= -3/2
Slope-intercept:
