Answer:

The red car is faster compared to the blue car.

The red car is faster by 5.5 feet than the blue car.

Step-by-step explanation:

The objective is to find which car is  faster and by how much

Given that:

The blue car traveled 54 feet in 4 seconds; &

The red car traveled 38 feet in 2 seconds.

Let us determine the number of feet traveled in each second for both cases.

For the blue car:

In 1 second, the car will travel = 54/4 feet

In 1 second, the car will travel = 13.5 feet

For the red car:

In 1 second, the car will travel = 38/2 feet

In 1 second, the car will travel = 19 feet

Thus, the red car is faster compared to the blue car.

The distance at which the red car is faster than the blue car = 19 feet - 13.5 feet

= 5.5 feet

Answer:

B

Step-by-step explanation:

Answer:

A. x = 6

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + b^2 = 10^2

64 + b^2 = 100

b^2 = 100 - 64

b^2 = 36

√b^2 = √36

b = 6

Answer:

No, the simplification is not done correctly. When multiplying

[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.

the correct answer is 12k-8

Step-by-step explanation:

We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.

The steps given are:

[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11[/tex]

No, the simplification is not done correctly. When multiplying

[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.

Correcting the error:

[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 6 + 8k - 2\\=12k - 8[/tex]

So, the correct answer is 12k-8

Answer:

the Slope is -6/5  and y is (0,-3)

Step-by-step explanation:

we need to put this equation in y = mx + b  

6x - 5y = -15  u will subtract 6x from both sides

5y = -6x -15...divide both sides by 5

and then simplify

y = -6/5x - 3

and when u  graph its will be (0,-3)

ur slope(m) = -6/5 and ur y int (b) = -3

Answer:

-1

Step-by-step explanation:

The formula is Y=mx+b and m is the slope while b is the y-intercept. So you plug in your numbers and i believe -1 is your y-intercept. :)

Answer:

(A).  [tex]\frac{15}{2}[/tex] + [tex]\frac{33}{4}[/tex] k

Step-by-step explanation:

[tex]\frac{3}{4}[/tex] × 2(2 + 4k + 3 + [tex]\frac{3}{2}[/tex] k ) = [tex]\frac{3}{2}[/tex] ( 5 + [tex]\frac{11}{2}[/tex] k ) = [tex]\frac{15}{2}[/tex] + [tex]\frac{33}{4}[/tex] k

Answer:

(x + 1)² + (y - 6)² = 50

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius.

The radius is the distance from the centre to a point on the circle.

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)

r = [tex]\sqrt{(-6+1)^2+(1-6)^2}[/tex]

  = [tex]\sqrt{(-5)^2+(-5)^2}[/tex]

  = [tex]\sqrt{25+25}[/tex]

  = [tex]\sqrt{50}[/tex]

(h, k ) = (- 1, 6 ), then

(x - (- 1))² + (y - 6)² = ([tex]\sqrt{50}[/tex] )² , that is

(x + 1)² + (y - 6)² = 50 ← equation of circle

Step-by-step explanation:

Answer:

Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.

Step-by-step explanation:

I'll answer this question using the following illustration.

Let a fraction be:

[tex]\frac{1}{2}[/tex]

and another fraction

[tex]\frac{1}{4}[/tex]

Both numerators are 1. In other words, they are equal

When you compare the denominator, 2 and 4, the fraction with lesser denominator is greater

This is so because:

[tex]\frac{1}{2} = 0.5[/tex]

[tex]\frac{1}{4} = 0.25[/tex]

By comparison

[tex]0.5 > 0.25[/tex]

This analysis can  be used for any fraction as long as they have the same numerator

Hence, option A answers the question

-12 does not equal 0

Answer: x=3, y-3

Step-by-step explanation:

I would use elimination

Multiply second equation by 2

2x + 2y = 12

2x + 3y = 15

Subtract both

-1y = -3, y = 3

Plug in 3 for y in any equation

x + 3 = 6, x = 3

Final answer: x = 3, y = 3
