A group of 46 friends are going to a beach house in
Pismo for the weekend. They plan on renting small cars
and large cars to make the trip.
Each small car can hold 2 people and each large car
can hold 4 people. They rented 8 more small cars than
large cars.
Determine the number of small cars they rented and
the number of large cars they rented.
1) Define your variables with "Let" statements.

A Group Of 46 Friends Are Going To A Beach House InPismo For The Weekend. They Plan On Renting Small

Answers

Answer 1
5 large cars, 13 small cars

Let s = # of small cars (2 people)
Let l = # of large cars (4 people)

2s + 4l = 46
l + 8 = s

2(l + 8) + 4l = 46
2l + 16 + 4l = 46
6l = 30
l = 5

Check:
2s + 4l = 46
2(13) + 4(5) = 46
26 + 20 = 46
46 = 46
Answer 2
small car (x) seat 2 people
large car (y) seat 4 people
Total number of people is 46
8 more small cats than large cats(8+y=x)
2x+4y=46
x=8+y
2(8+y)+4y=46
16+2y+4y=46
6y=46-16
6y=30
y=30/6
y=5 aka 5 large cars

x=8+y
x=8+5
x=13 aka 13 small cars

2•13+4•5=26+20=46 seats for everyone

Good luck.

im stuck on matching functions to graph with function notation. i dont know what to do. Someone please help.

Answers

Answer:

Since the function notation lets us write f(x) instead of y, the graph of a function f is the set of all points (x, f(x)), where x is in the domain of the function. example Graph f(x) = 5x - 1 and find the value of f(3) by using the graph. The y-intercept is -1 and the slope is 5. When x = 3, y equals 14.

Given:

The edge length of a cube = 6 inches

To find:

The volume of the cube.

Solution:

We know that, the volume of a cube is

[tex]V=a^3[/tex]            ...(i)

Where, a is the edge length.

Substituting a=6 in (i), we get

[tex]V=(6)^3[/tex]

[tex]V=216[/tex]

Therefore, the total volume of the cube is 216 cubic inches.

hope this helps

Answer:

[tex]\frac{141}{92}[/tex]

Step-by-step explanation:

1) First, convert the mixed numbers to improper fractions.

[tex]5\frac{7}{8}[/tex] ÷ [tex]3\frac{5}{6}\\[/tex]

[tex]=\frac{47}{8}[/tex] ÷ [tex]\frac{23}{6} \\[/tex]

2) To divide fractions, find the reciprocal of the second fraction by flipping it, or switching the places of its numerator and denominator. Then, multiply the two fractions by multiplying their numerators and denominators together. Then, simplify the result to find the answer.

[tex]\frac{47}{8}[/tex] × [tex]\frac{6}{23}[/tex]

[tex]=\frac{282}{184} \\=\frac{141}{92}[/tex]

Answer to the question ;

Directions: calculate the rise,run, and slope on the line below

Answers

Answer: Rise = 3 Run=1  slope=3/1 or just 3

Step-by-step explanation:

start at the left most point and count up to the line that contains the 2nd point

so rise 3

then count over to that 2nd point

so run is 1

slope is rise/run so 3/1

rise = y₂-y₁ = 1 - (-2) = 1+2 = 3

run = x₂-x₁ = 1-0 = 1

slope = rise / run

slope = 3/1

slope = 3

Calculate the distance between the points f=(-8,5) and k=(-4,1) in the coordinate plane round your answer to the nearest hundredth

Answers

Answer:

5.66

Step-by-step explanation:

Given data

the coordinates are

f=(-8,5) and

x1= -8

y1= 5

k=(-4,1)

x2= -4

y2= 1

The distance can be expressed using the formula

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-4+8)²+(1-5)²)

d=√((4)²+(-4)²)

d=√16+16)

d=√32

d=√32

d=5.656

Hence the distance between the points is 5.66

Figure JKLM is dilated by a scale factor of 1 over 3 with the center of dilation at the origin. What are the coordinates for the vertices of the new image?v

Answer:

It’s A

Step-by-step explanation:

I took the test

If it is dilated by a  scale factor of 1/3 with the center of dilation at the origin, The new point is at J'(-1, 2), K'(2, 2), L'(1, 1) and M'(0, 1).

Transformation

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is dilated by a scale factor of k, the new point is at A'(kx, ky).

JKLM has vertices at J(-3, 6), K(6, 6), L(3, 3) and M(0, 3). If it is dilated by a  scale factor of 1/3 with the center of dilation at the origin, The new point is at J'(-1, 2), K'(2, 2), L'(1, 1) and M'(0, 1).
