Answer:
x≥−3
Step-by-step explanation:
Let's solve your inequality step-by-step.
−4x−10≤2
Step 1: Add 10 to both sides.
−4x−10+10≤2+10
−4x≤12
Step 2: Divide both sides by -4.
−4x
/−4
≤
12
/−4
= x≥−3

Answer:
key features are the slopes of both linear functions, if they are not equal then the two linear functions will be intercepted
Step-by-step explanation:
Any linear function can be represented by the following linear equation:
y=mx+b
where m is the slope of function
and y in the intercept
Given:
The SneakerRama Company makes and sells sneakers.
They have one linear function that represents the cost of producing sneakers
Let it be represented by y₁=m₁x+b₁
and another linear function that models how much income they get from those sneakers
Let it be represented by y₂=m₂x+b₂
Now if m₁≠m₂
then the two functions will intercept at some point on the graph at some value of x. At that point the cost of producing sneakers will be equal to income they get from those sneakers.
y₂-y₁=0
This point is called the break-even point and the profit is zero at this point !
Answer:
see explanation
Step-by-step explanation:
given the 2 equations
y = x² - 2x - 19 → (1)
y + 4x = 5 → (2)
substitute y = x² - 2x - 19 into (2)
x² - 2x - 19 + 4x = 5 ( subtract 5 from both sides )
x² + 2x - 24 = 0 ← in standard form
(x + 6)(x - 4) = 0 ← in factored form
equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 4 = 0 ⇒ x = 4
substitute each value of x into (1) for corresponding y- coordinate
x = - 6 : y = (- 6)² - 2(- 6) - 19 = 36 + 12 - 19 = 29 ⇒ (- 6, 29)
x = 4 : y = 4² - 2(4) - 19 = 16 - 8 - 19 = - 11 ⇒ (4, - 11)
the solutions are (- 6, 29), (4, - 11)
