y = 1/3x + 3

Step-by-step explanation:

Slope form of a equation: y = mx + b. The slope is 1/3, so y = 1/3x + b

Solve for b by plugging the (x, y) coordinate into the equation.

y = 1/3x + b

2 = 1/3(-3) + b

2 = -3/3 + b

2 = -1 + b

b = 3

So your answer is y = 1/3x + 3

Alexia ran three laps around her neighborhood. Each lap is 1 and StartFraction 3 over 8 EndFraction miles. Which is the best estimate of the number of miles that Alexia ran?
2 miles
3 and one-half miles
4 and one-half miles
6 miles

Answers

Answer:

4 and one-half miles

Step-by-step explanation:

The answer closest to the correct answer is 4 and one-half miles.

To get the answer, you multiply 3 times the length of one lap which is 1 and [tex]\frac{3}{8}[/tex] miles.  To multiply the fraction, you take 3 times the top number in the fraction.  So 3 x 1 [tex]\frac{3}{8}[/tex] = 3 [tex]\frac{9}{8}[/tex].  The fraction can actually be reduced to 1 and [tex]\frac{1}{8}[/tex] miles.  So you're total correct answer is 4 and [tex]\frac{1}{8}[/tex] miles.

The second selection is 3 and [tex]\frac{1}{2}[/tex] which can also be written as 3 and [tex]\frac{4}{8}[/tex] to make it easier to determine which answer is correct.  The second answer is therefore [tex]\frac{5}{8}[/tex] shorter than the correct answer.

The third selection is 4 and [tex]\frac{1}{2}[/tex] which can be written as 4 and [tex]\frac{4}{8}[/tex] so it is only [tex]\frac{3}{8}[/tex] longer than the correct answer.  So this selection is the closest to the actual miles ran.

Estimate. Then find the product.

Step-by-step explanation:

What is the perimeter of a polygon with vertices at (-3, 1), (5, 1), (-3, 4), (5, 4)?

Answers

Answer:

The perimeter of the polygon is 22.

Step-by-step explanation:

Let [tex]A(x,y) =(-3,1)[/tex], [tex]B(x,y) = (5,1)[/tex], [tex]C(x,y) = (-3, 4)[/tex] and [tex]D(x,y) =(5,4)[/tex] the vertices of the polygon. From Geometry we know that number of side of polygons equals their number of vertices, then we notice that a quadrilateral is here. In addition, we conclude that such quadrilateral is a rectangle:

1) [tex]x_{A} = x_{C}[/tex]

2) [tex]x_{B} = x_{D}[/tex]

3) [tex]y_{A} = y_{B}[/tex]

4) [tex]y_{C} = y_{D}[/tex]

Hence, we find that [tex]AB = CD[/tex] and [tex]AC = BD[/tex].

Then we find all lengths of the rectangle by Pythagorean Theorem:

[tex]AB = \sqrt{[5-(-3)]^{2}+(1-1)^{2}}[/tex]

[tex]AB =8[/tex]

[tex]AC = \sqrt{[(-3)-(-3)]^{2}+(4-1)^{2}}[/tex]

[tex]AC = 3[/tex]

By Geometry, we conclude that [tex]CD = 8[/tex] and [tex]BD = 3[/tex].

Then, the perimeter of the rectangle ([tex]p[/tex]), dimensionless, is defined by the following formula:

[tex]p = 2\cdot (s+l)[/tex] (Eq. 1)

Where:

[tex]s[/tex] - Shortest length, dimensionless.

[tex]l[/tex] - Longest length, dimensionless.

If we know that [tex]s = 3[/tex] and [tex]l = 8[/tex], then the perimeter of the rectangle is:

[tex]p = 2\cdot (3+8)[/tex]

[tex]p = 22[/tex]

The perimeter of the polygon is 22.

A conservative estimate of the number of stars in the universe is 6x10^22. The average human can see about 3,000 stars at night with his naked eye.About how many more times more stars are there in the universe compared to the stars human can actually see?

Answers

Answer:

2 × 10^19 times

Step-by-step explanation:

Number of stars in universe = 6x10^22

Number of stars eye can see = 3000

About how many more times more stars are there in the universe compared to the stars human can actually see?

Number of stars in universe / number of stars eye can see

= 6x10^22 / 3000

= 6 × 10^22 / 3 × 10^3

= 2 × 10^(22 - 3)

= 2 × 10^19 times

Number of stars in universe is 2 × 10^19 times more than that which the eyes can see

Angle TRS would be 180-45x as the angle lies on a straight line and we know angles on a straight line add up to 180 degrees

Then I would add the three angles in the triangle and equate it to 180 degrees as angles in any triangle add up to 180 degrees

therefore:

(180-45x)+25x+(57+x)=180

180-45x+26x+57=180

237-19x= 180

237-180=19x

57=19x

57/19=x

3=x

x is correct as when we substitute it in the angles in the triangle, the interior angles for the triangle does add up to 180

On Thursday a local hamburger shop sold a combined total of 444 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold

Answers

Answer:

148 hamburgers sold

296 cheeseburgers sold

Step-by-step explanation:

x  = number of hamburgers sold

2x = number of cheeseburgers sold

444 = total burgers sold

hamburgers + cheeseburgers = total burgers sold

x + 2x = 444

3x = 444

3x/3 = 444/3

x = 148

Check:

148 + 2(148) = 444

148 + 296 = 444

444 = 444

Identify the range of the function shown in the graph.

A. 0 ≤ y ≤ 8
B. -6 ≤ x ≤ 6
C. y > 0
D. y is all real numbers.

Answers

Answer:

[tex]0\leq y\leq 8[/tex]

Step-by-step explanation:

because it cant go below x-axis with is y = o and nothing above 8

The function can produce any y-value between 0 and 8, including both 0 and 8 (option a).

The range of a function refers to the set of all possible output values, or y-values, that the function can produce. To identify the range of the function shown in the graph, we need to determine the highest and lowest y-values that the graph reaches.

Looking at the graph, we can see that the highest point on the graph is at y = 8, and the lowest point is at y = 0. Therefore, the range of the function is from y = 0 to y = 8.

In other words, the function can produce any y-value between 0 and 8, including both 0 and 8. We can express this range using interval notation as [0, 8].

So, the correct answer is option A: 0 ≤ y ≤ 8.

Answers

Answer:

(-17 + 9) - 15

Step-by-step explanation:

I think of below sa level as negative numbers, so 17 feet below sea level is -17. Then when he rises 9 feet that would be - 17 + 9. When he decends 15 feet to take another picture thats - 15. Then when you thing of pemdas addition goes first, so i just put parentases around -17 + 9 to get the expression (-17 + 9) - 15

Write a linear equation in slope intercept from that is perpendicular to x−3y=3 and passes through the point (5, −9).

Answers

Answer:

[tex]y=-3x+6[/tex]

Step-by-step explanation:

First, let’s determine the slope of the original equation.

We have [tex]x-3y=3[/tex]

Subtract x from both sides and then divide both sides by -3. So:

[tex]-3y=-x+3\\y=\frac{1}{3}x-1[/tex]

Therefore, the slope of our original line is 1/3.

Remember that perpendicular lines have slopes that are negative reciprocals of each other.

Therefore, the slope of our new perpendicular line is the negative reciprocal of 1/3.

Thus, the slope of our new line will be -3. We flip the fraction and add a negative.

So, the slope of our new line is -3. We also know that it passes through the point (5, -9).

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, substitute -3 for m and (5, -9) for (x₁, y₁). This yields:

[tex]y-(-9)=-3(x-5)[/tex]

We want our line in slope-intercept form. So, distribute the right:

[tex]y+9=-3x+15[/tex]

Subtract 9 from both sides. Therefore, our equation is:

[tex]y=-3x+6[/tex]

You had a lot of spare time this summer because of quarantine, so you and four family members took a 5-day white-water rafting and hiking trip. During your 5-day trip, 2 days were spent rafting. If the rafting trip covered a distance of 60 miles and you spent 8 hours rafting each day, how many miles did you raft each hour?

Answers

Answer:

3.75 miles per hour

Step-by-step explanation:

Given that:

Number of days spent rafting = 2 days total distance covered during rafting = 60 miles

Time spent rafting per day = 8 hours

Number of miles raft per hour:

Total number of raft hours over the 2 days = (8 * 2) = 16 hours

Total raft distance over the 2 days = 60 miles

Raft miles per hour :

Total raft distance / total number of raft hours

60 miles / 16 hours

= 3.75 miles per hour
