Answer:

Domain = all real numbers

Range = y ≥ -4

Step-by-step explanation:

Domain is the x-values, and for parabolas it is almost always all real numbers.

Range is the y-values, and the lowest it gets is -4.

Answer:

The f(x) domain is the set of all values for the function and the function spectrum is the set of all values for which f is defined.

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?

UNO [17]

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

$1\frac{2}{3}$ × 3

$1\frac{2}{3}$ can be rewritten as $\frac{5}{3}$ , so:

$\frac{5}{3}$ × $\frac{3}{1}$

$= \frac{15}{3}$

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

hope this helps!

The sophomore class is planning to sell school mascot puppets to help cover the cost of a class trip. A local supplier will char

kifflom [539]

Answer:

755 or more

Step-by-step explanation:

The profit is the difference between revenue and costs. We want the profit to be $2000 or more, and we have both fixed and variable costs.

Let x represent the number of puppets sold. Then the costs are ...

... 76.25 + 2.25x

The revenue is 5x.

The above-described relationship can then be written as

... 5x -(76.25 +2.25x) ≥ 2000

... 2.75x ≥ 2076.25 . . . . . add 76.25, collect terms

... x ≥ 2076.25/2.75 . . . . divide by the coefficient of x

... x ≥ 755

755 or more puppets must be sold to earn $2000 or more.

Solve the inequality and then graph it t-3 < -2

SSSSS [86.1K]

Hi there!

Answer:

t<1

*The answer must have a positive sign.*

Step-by-step explanation:

First, you add by 3 from both sides of an equation.

$t-3+3$

And then, you add/subtract from left too right.

$(-2)+3=-1$

It change negative to positive sign.

Final answer is t<1

Hope this helps!
