Answer:

[tex]1[/tex] solution

Step-by-step explanation:

Let's try to solve this and see where we get.

We can add 3x to both sides of the equation to get [tex]3+4x=2[/tex].

We can then subtract 3 from both sides of the equation to get [tex]4x=-1[/tex].

We lastly divide both sides of the equation by 4 to get [tex]x=-1/4[/tex].

Because all of our steps are reversible(for instance, when we divide by 4, we can multiply(the "reverse" of division) by 4, so dividing by 4 is reversible), there is only [tex]\boxed{1}[/tex] solution, [tex]x=-1/4[/tex].

Domain: [-2, ∞)

Range: [-4, ∞)

General Formulas and Concepts:

Algebra II

Coordinate Planes

Step-by-step explanation:

According to the graph, we see that our x-value stretches from x = -2 to infinity. Since x = -2 is a closed dot, it is included in the domain:

[-2, ∞) or -2 ≤ x < ∞

According to the graph, we see that our y-value stretches from y = -4 to infinity. Since y = -4 is a closed dot, it is included in the range:

[-4, ∞) or -4 ≤ y < ∞

Answer:

Shai received $192 while Mara received $288.

Step-by-step explanation:

Let u be 1 unit.

5u=$160

u=$160÷5

=$32

6u=$32×6

=$192

9u=$32×9

=$288

Answer: B) 19

Step-by-step explanation:

To solve this problem, simply plug in -4 for x:

[tex]f(x)=x^{2} +3\\f(x)=(-4)^{2} +3\\f(x)=16+3\\f(x)=19[/tex]

Hope it helps :) and let me know if you want me to elaborate/explain further

Answer:

D. -13

Step-by-step explanation:

If you substitute -4 in for x you get -4^2+3, so when you simplify you get -16+3 which equals -13.

f(x)=x^2+3

f(-4)= -4^2+3

f(-4)= -16+3

f(-4)= -13

Algebraic equations are equations that have coefficients and unknown variables in them.

The equation to show how many ounces of spicy sauce Bert's uncle usually put in is given as: 3(u - 2) = 24

The amount of hot sauce  Bert's uncle usually puts in each batch of spicy wing sauce is 10 ounces.

Let's represent each ounce of hot sauce as u

Hence, the equation to show how many ounces of spicy sauce Bert's uncle usual put in is given as:

3(u - 2) = 24

The amount of hot sauce Bert's uncle puts in the spicy wing sauce

3(u - 2) = 24

3u - 6 = 24

Collect like terms

3u = 24 + 6

3u = 30

Divide both sides by 3

u = 30/3

u = 10

Bert's uncle puts 10 ounces of hot sauce in the spicy wing sauce.

Answer:

option number 3

Step-by-step explanation:

Answer:

[tex]3 + d \leqslant 3 - d \\ d + d \leqslant 3 - 3 \\ 2d \leqslant 0 \\ d \leqslant 0 \\ thank \: you[/tex]

1) Cancel 3 on both sides

d≤−d

2) Subtract -d from both sides.

d+d≤0

3) Simplify  d+d  to  2d.

2d≤0

4)  Divide both sides by 2.  

d≤0

I hope this helps.

Step-by-step explanation:

145 miles. lets see how i got this.

so first i took the 2.5 hour trip and the average speed, which was 58 mph (or 93.3 kph), and multiplied them together, because of the rule of d=rt.

sidenote: also if you want to find the speed, use r=d/t. also, for finding the time, use the t=d/r rule.

side-sidenote: i hope this answers your question and helps you in the future.

key: r= rate (mph or kph), d=distance, and t=time.

Answer:

a=19

Step-by-step explanation:

8=1/3(a+5)            by dividing both sides by 1/3

24 = a+5              get 5 to other side with oposite sign

24-5 = a

a = 19

Answer:

a = 19

Step-by-step explanation:

8 = [tex]\frac{1}{3}[/tex] ( a + 5) ← multiply both sides by 3 to clear the fraction

24 = a + 5 ( subtract 5 from both sides )

19 = a

Answer:

Harriet's Hair Styles

Step-by-step explanation:

Frank's Furters $6.24 /hr

Harriet's Hair Styles $80 for 12 hours weekly

$80 / 12 hr = $6.66/hr

Babysitting $250 a month for 10 hours after school a week. (Assume 4 weeks is a month.)

$250 / (4 wk * 10 hr/wk) = $250/ 40 hr = $6.25/hr

Answer: Harriet's Hair Styles

Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.

To determine which job has the highest hourly pay, we need to calculate the hourly wage for each job based on the information provided.

Frank's Furters: $6.24 per hour.

Harriet's Hair Styles: $80 for 12 hours weekly.

Babysitting: $250 a month for 10 hours after school a week.

Let's calculate the hourly wage for each job:

Frank's Furters: $6.24 per hour.

Harriet's Hair Styles: $80 for 12 hours weekly

= $80 / 12 hours

= $6.67 per hour.

Babysitting: $250 a month for 10 hours after school a week

= $250 / (4 weeks x 10 hours)

= $6.25 per hour.

Hence, Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.

Answer:

3x = 5

Step-by-step explanation:

9x = 4x + 5

-4x -4x

3x = 5

Answer:

h(x) = 4x + 5       h(x) = 9

9 = 4x + 5        9 - 5 = 4  and 5 - 5 = 0

4 = 4x          4 divided by 4 equals 1

Answer is x = 1.

--------------------------------------------------------

Check your answer:

9 = 4x + 5

Input the 1 into the variable x's place in the equation.

9 = 4 X 1 + 5

And now solve.

4 X 1 + 5 = 9

So, now we know that our answer is fully correct.
