Step-by-step explanation:

-2/3

from the y-intersect (0,0), you went up 2 units(positive) and left 3 times (negative) to get the other points so negative and positive are negative.

C. Preform calculations on my own and compare them to Roberto’s.

Step-by-step explanation:

His calculations do not match the line plot. He doesn’t account for every mark on the plot.

Answer:

Step-by-step explanation:

From the table attached,

x-intercept of the linear function is, the value of 'x' when f(x) = 0  

x = 3 [x-intercept]

Function 'g' is the sum of 2 and the cube root of the sum of three time x and 1.

g(x) = [tex]2+\sqrt[3]{3x+1}[/tex]

For x-intercept,

g(x) = 0

[tex]2+\sqrt[3]{3x+1}=0[/tex]

3x + 1 = (-2)³

3x + 1 = -8

3x = -8 - 1

3x = -9

x = -3

Therefore, the x-intercept of function 'f' is different or greater than the x-intercept of function g.

Answer for 4

box one 1/4

box 2 4/10

box 3 3/4

Answer:

[tex]1-8x-2x^2[/tex]

Step-by-step explanation:

(-4x^3-14x^2+10x-1)÷(2x-1)

Factor the expressions that are not already factored.

[tex]\frac{(2x-1)(2x^2-8x+1)}{2x-1}[/tex]

Cancel out 2x−1 in both numerator and denominator.

[tex]2x^2-8x+1[/tex]

Swap terms to the left side.

[tex]1-8x-2x^2[/tex]

Graph if needed:

Answer:

B:-1

Step-by-step explanation:

Just took test 2021

Answer:

Step-by-step explanation:

The given function is a piecewise function with characteristics that vary with the value of x.

Please find attached the graph of h(x).

Reasons:

The given information is presented as follows;

From the above piecewise function, we have;

For x ≤ 0, the slope of the graph of h(x) =

For 0 < x ≤ 3, the slope of the graph of h(x) =

For x ≥ 4, the slope of the graph of h(x) =

Therefore, as we progress from left to right, the slope of h(x) increases and

the slope of the graph becomes steeper.

The graph of h(x) is plotted with the given equations using MS Excel as

shown in the attached diagram.

Answer:

121.5

Step-by-step explanation:

75% =  75/100

Step 2 - Mutiply percenatge fraction by the entire (100%) quantity

75/100× 162 = 121.5

Final result

75 percent of 162 is 121.5

Answer:

121.5

Step-by-step explanation:

| percantage x 100% |

75/100 x 162 = 121.5

Answer:

I think 4

Step-by-step explanation:

1/3 is how many are yellow. so if u do 12/3=4

Answer:

4

Step-by-step explanation:

1/3 is equivalent to 4×1 and 2/3 is equivalent to 4×2 and 3/3 is equivalent to 4×3 which equals 12 so there are 4 counters that are yellow.

Answer:

15 years

Step-by-step explanation:

Create an equation where x is the number of years

32,000 + 600x = 56,000 - 1000x

Solve for x:

600x = 24,000 - 1000x

1600x = 24,000

x = 15

So, it will take 15 years for both cities to have the same number of residents

Step-by-step explanation:

Answer:

D. 22 Cars and 8 Vans

Step-by-step explanation:

1. You multiply 22 x 150 = 3,300.

2. Then you multiply 300 x 8 = 2,400.

3. Next, add 3,300 + 2,400

4. That equals 5700.

Hopefully, that helps!

Answer:

256 cups

Each gallon has 16 cups so 16 gallons would have 16*16 cups. 16*16 = 256

Answer:

1) Option (b) 32km

2) Option (c) 17

Step-by-step explanation:

According to Pythagoras Theorem,

Hypotenuse²=Perpendicular²+Base²

H²=P²+B²

1) Perpendicular=?

Base=24km

Hypotenuse=40km

40²=P²+24²

1600=P²+576

1600-576=P²

1024=P²

√1024=P

32=P

2) Perpendicular=15

Base=8

Hypotenuse=?

H²=15²+8²

H²=225+64

H²=289

H=√289

H=17

Answer:

8

Step-by-step explanation:

0) the basic formula is: L=v*t, where L - distance, v - speed/velocity; t - time;

1) if the person's speed in still water is 'v' and the speed of water is 5 (according to the condition), then the upstream speed is 'v-5' and the downstream speed is 'v+5';

2) according to the condition the upstream time and the downstream time are the same, it means t₁=t₂=t, where t₁=upstream time and t₂=downstream time;

3) according to the items above it is possible to make up the equation of the upstream travel: t(v-5)=3; ⇒ t=3/(v-5);

4) according to the items above it is possible to make up the equation of the downstream travel: t(v+5)=13; ⇒ t=13/(v+5);

5) if t=3/(v-5) and t=13/(v+5), then

[tex]\frac{3}{v-5} =\frac{13}{v+5}; \ => \ v=8.[/tex]
