Step-by-step explanation:
2x+(x)(3+x) multiple or foil the ()
2x+3x+x^2 combine like terms
5x+x^2 or x^2+5x
Answer:
its D
Step-by-step explanation:
In a right triangle the hypotenuse which is 16+9 =25 has to be the largest side. Since x is not the hyportenuse it has to be lower which only leaves one answer : 15
Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)
if the equation has a negative slope that will indicate that the slope is negative
ex. y=-<u>5x</u>+6
