Answer:
The solution is A. (-2,7) and C. (3,2)
Step-by-step explanation:
x+y = 5 ............(1)
x²+y = 11 ............(2)
_________________________
y = 5-x
x²+(5-x) = 11
x²+5-x-11 = 0
x²-x-6 = 0
x²+2x-3x-6 = 0
(factor statement)
x(x+2)-3(x+2) = 0
(x+2) (x-3) = 0
x+2=0 x-3 =0
x = -2 x = 3
(x1 = -2, x2 = 3)
_________________________
y = 5-x
y = 5-(-2) ............(1)
= 7
y = 5-3 ............(2)
= 2
(y1 = 7, y2 = 2)
_________________________
(x1,y1) & (x2,y2)
(-2,7) & (3,2)
So, A. (-2,7) and C. (3,2) correct

Justin is taking a taxi cab to pick up his car from the auto shop. The taxi charges an initial fee of $5.00 and additional $2.50 for each mile the taxi drives. Write an equation using x as the number of miles, to determine how many miles the taxi drove if Justin spent $25.00. Use your equation for the number of miles. (Define the variable please, write an equation, and solve & label:))
Answers
Answer:
x = 8
Step-by-step explanation:
Given the initial fee of $5.00, and the additional cost of $2.50 for every mile the taxi drives:
We can establish the following cost function:
C(x) = 2.50x + 5.00
Where:
C(x) = total cost of taxi fare (same as the variable, "y" in linear equation)
x = number of miles driven
$5.00 = initial or flat fee (same as the y-intercept, "b," in linear equation).
We can find out the number of x miles the taxi drove for the $25.00 total cost that Justin paid for the fare:
C(x) = 2.50x + 5.00
$25 = 2.50x + 5.00
Subtract 5.00 from both sides of the equation:
$25 - 5.00 = 2.50x + 5.00 - 5.00
$20 = 2.50x
Divide both sides by 2.50 to solve for x:
[tex]\frac{20}{2.50} = \frac{2.50x}{2.50}[/tex]
8 = x
Justin spent $25 for a taxi ride that travelled for 8 miles.

Answers
Answer:
-4
Step-by-step explanation:
you will have to replace the n with -7, that means,
(-7+5)2
when a number is beside a bracket, it automatically means multiply
you will have to solve the numbers in the bracket first
-7 +5 is equal to -2
then, -2 multiplied by 2 is equal to -4
Answer:

Explain what the algebraic solution of a system of two linear equations is and what that means in terms of the graphs of the equations of the system. Use AT LEAST 2 complete sentence in
your explanation. (3 points)
Answers
The goal of the method of substitution is to reduce a system of two linear equations in two variables to a single equation in one
variable.
The key step in using method of elimination is to obtain opposite coefficients for one of the variables so that adding the two equations eliminates this variable.
Solving systems of linear equations by graphing involves sketching the lines representing the equations to determine whether the lines intersect at a point, which is the solution of the system.
