What is the solution for the system of equations? y=−x+4 y= x−2
Answer:
(3, 1 )
Step-by-step explanation:
Given the 2 equations
y = - x + 4 → (1)
y = x - 2 → (2)
Substitute y = x - 2 into (1)
x - 2 = - x + 4 ( add x to both sides )
2x - 2 = 4 ( add 2 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (2)
y = 3 - 2 = 1
solution is (3, 1 )

For this right triangle drawn on the coordinate plane what calculation could be used to find the length of a C?
Answer:
AB^2 + BC^2 = AC^2
Step-by-step explanation:
the pythagorean theorem( a^2 + b^2 = c^2) is used to solve for the hypotenuse which in this case is AC
^2 means squared incase you didnt know

Tickets to a band concert cost $10 each. The equation y = 10x represents total cost, y, of x tickets. Which graph shows ordered pairs represented by this equation?
Answer:
the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.
Step-by-step explanation:
Given the function equation
y = 10xGiven that the cost of each ticket is $10.
It means:
at x = 0, y = 10(0) = 0 ∵ cost of 0 ticket
at x = 1, y = 10(1) = 10 ∵ cost of 1 ticket
at x = 2, y = 10(2) = 20 ∵ cost of 2 tickets
at x = 3, y = 10(3) = 30 ∵ cost of 3 tickets
at x = 4, y = 10(4) = 40 ∵ cost of 4 tickets
at x = 5, y = 10(5) = 50 ∵ cost of 5 tickets
Now, observe the ordered pairs points on the right-hand graph of the first diagram.
This graph has the following ordered pairs:
(0, 0) i.e. at x = 0, y = 10(0) = 0(1, 10) i.e. at x = 1, y = 10(1) = 10 (2, 20) i.e. at x = 2, y = 10(2) = 20 (3, 30) i.e. at x = 3, y = 10(3) = 30 (4, 40) i.e. at x = 4, y = 10(4) = 40 (5, 50) i.e. at x = 5, y = 10(5) = 50Thus, the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.

If Mt. Whitney is 14,505 feet above sea level, and the bottom of the Salton Sea is -52 feet below sea level, what is the difference, in feet, between the elevation at Mt. Whitney and the Salton Sea?
Answer:
14557 feet
Step-by-step explanation:
The sea level is considered to be zero, so that elevation is positive while depth is negative.
Mt. Whitney is 14,505 feet above sea level.
Salton Sea is -52 feet below sea level.
Difference = Mt. Whitney elevation - Salton Sea depth
= 14505 - (-52)
= 14505 + 52
= 14557
Difference = 14557 feet
The difference between Mt. Whitney and Salton Sea is 14557 feet.

Which equations can be represented by the line that contains the points (6. 8) and (2. 6)?
Answer:
y=1/2x+5
Step-by-step explanation:
first you have to find the slope by using [tex]\frac{y2-y1}{x2-x1}[/tex]
so when you plot in your points and you will get 1/2x.
then you need to find your y-intercept
and since you don't have a 0 you have to slove by using y=mx+b (slope-intercept) formula
you plug in your points and you will get
b=5 and that is how you get your equation.
Which graph represents a linear function of x?
Answer:
A
Step-by-step explanation:
if 7(p+3)= -28 then what does p equal
Answer:
p = -7
Step-by-step explanation:
7(p+3) = -28
now we times the inside of the parenthese by 7
7p+21 =-28
now we minus 21 on both sides
7p= -49
now divide
p = - 7
Answer:
-7
Step-by-step explanation:
7(p+3) = -28
Divide by 7
7(p+3) / 7 = -28 / 7
p+3 = -4
Subtract 3
p+3 (-3) = -4 (-3)
P = -7
