Answer:
slope is 1
Step-by-step explanation:
5-3/-4--6 = 2/2 = 1
So for this problem, you will need to write out the equation before you can solve the question. The square of two times an integer translates into 2x². In a word problem, "is" means =. Therefore, 2x² is equal to the other half of the equation. To write out the other half of the equation, you have to know that "is more than" means addition. So, 10x+6 is the other half of the equation. your final equation becomes 2x²=10x+6. Then solve the equation like in any other problem: 2x²=10x+6 becomes 2x²-10x-6=0, and then factor or use the quadratic formula.
Your answer is -9x I'm 100% sure
I hope this helps
Answer:
Step-by-step explanation:
Number 2 first:
See the graph below for a hint. (Do you know how to use Desmos ?)
factoring seems to make no sense for
but "guess and check" seems to work. I tried 4 for x, but that proved false. 3 for x made sense. You get
so -9 +6 +4 = 1 is true. So (3,1)
x+y=4 becomes 3 + 1 = 4 Also true
According to the graph, (0,4) would also be a solution, so (3,1) and (0,4)
Part 1:
Factor
as
set each equal to 0 and get
x = -3 and x = -1 so the solutions seem be (-3,0) and (-1,0)
y = 2x + 6 factors to 2(x +3)
(-1,0) doesn't work!
But Desmos shows something else as a solution set for both:
(1,8)
y=2x+6 substitute values 8=2(1) +6 8=2+6 True
y =
. Substitute values
8= 1+4+3 True
