Answer:
Johnny wants to buy a game but he doesn't have enough money. He needs to have at most $60 to buy his game. He has $5 in his piggy bank and gets $11 for every hour for working. Write an inequality where x represents his hours.
11x + 5 ≤ 60
Not that good but its better than nothing.
Answer:
3. Do Δy/Δx
Step-by-step explanation:
Do 10/3, which is an estimate. You get an answer of 3.3. Intuitively this makes sense because the slope is a constant positive value. And 1/3 is way too small of a number to describe the steepness shown
Or actually, do 3/1 because that would give the slope from x=0 to x=1. Since the slope is constant, that answer will apply for every single point on the function
Answer:
(x + 4) (x - 3) (x + 3)
Step-by-step explanation:
Answer:
Maybe the sum was a simultaneous equation....if so, this is the solution.
and the answer comes (1/3, 3)
Hope it helps! :)
Answer:
option D
(-1,-3) and (3,13)
Step-by-step explanation:
Given in the question two equations
y = 4x + 1
y = x² + 2x - 2
Equate both functions
4x + 1 = x² + 2x - 2
rearrange the x term and constant
-x² + 4x - 2x + 2 + 1 = 0
-x² + 2x + 3 = 0
factors
-x * 3x = -3x²
-x + 3x = 2x
-x² -x + 3x + 3 = 0
-x(x+1) +3(x+1) = 0
solve
(x+1)(3-x) = 0
x = -1
and
x = 3
Plug these values in equation to find y
x = -1
y = 4(-1)+ 1
y = -3
x = 3
y = 4(3)+ 1
y = 13
