Answer:
x = 1 y = 2
Step-by-step explanation:
you add the equations and get 3x equals 3 divide x by 3 get 1 x equals 1 substitute x in the first equation for 1 1 plus y equals three subtract one and y equals 2
Answer:
(-1,2)
Step-by-step explanation:
The solutions to the system is where the lines intersect
The lines intersect at the point (-1,2)
Answer:
first question: c. x = 1
6. B. y = -2x - 8
Step-by-step explanation:
first question:
perpendicular means that when it intersects, it makes a right angle.
the equation y = 5 would be parallel to any of the answers with y = ___ because all of those would result in horizontal lines
either of the x = ___ would be perpendicular to y = 5
since it has to pass through the point (1,3) that means that the equation must be x = 1
the equation x = 1 passes through any point beginning with (1 , _)
6.
parallel means that the equations have the same slope. therefore, we can eliminate both A and C
using the given point (-2 , -4),we can plug into the y = mx + b format to solve
m = -2 x = -2 y = -4
-4 = (-2)(-2) + b --> -4 = 4 + b --> b = -8
finally, our equation comes out to be y = -2x - 8
Answer:
5
Step-by-step explanation:
This is a problem most likely relating to order of operations (i.e. PEMDAS) where the letters stand for the order you should solve the problem in.
P= Parenthesis
E= Exponent
M= Multiplication
D= Division
A= Addition
S= Subtraction
With this in mind, I solved (14+3) and (2x6), which gave me 17 and 12 respectively. After I subtracted 12 from 17 and got 5 as the answer
3, because negative numbers are less than positive numbers. Therefore, 3 is correct
