Hey there!

Equation given :

50 + 5y - 20 = 14y - 12 - 2y

Combining like terms :

30 + 5y = 12y - 12

Adding 12 on both sides :

42 + 5y = 12y

Subtracting 5y on both sides :

7y = 42

Dividing by 7 on both sides :

y = 6

The value of y is 6.

The correct answer is A) as the x values go to positive infinity, then the graph goes to negative infinity.

We can tell this by looking at the graph values as x goes up. You'll notice, as we get higher and higher, the graph disappears down. This means it is heading towards negative infinity for the rest of the graph.

The statement  which is true about the end behavior of the graphed function is:

We know that the end behavior of the function is the value where it approaches when x tends to plus infinity and minus infinity.

 From the graph of the function we see that the graph first decreases continuously and then it increases and again it decreases to minus infinity.

Also,

when x → -∞ we see that  f(x) → ∞

and when  x → ∞ then f(x) → -∞

As the function has opposite behavior in both the directions this means that the function is odd.

At x=0 the value of function is: -2

None of them are equivalent to 0.3, unless it's 0.3 with a bar over the 3, in which case the answer is 1/3.

Rental car agency charge:

Let's assume number of miles in as week as x miles

and total rent as R(x)

A rental car agency charges $240 per week plus $0.25 per mile to rent a car

so, we get equation as

[tex]R(x)=240+0.25x[/tex]

Minivan charge:

Let's assume number of miles in as week as 'x' hours

and total charge of minivan as M(x)

The charge for a minivan is $180 per week plus $0.40 per mile

so, we get

[tex]M(x)=180+0.40x[/tex]

now, we can set them equal

and then we can solve for x

[tex]240+0.25x=180+0.40x[/tex]

Subtract both sides by 0.25x

[tex]240+0.25x-0.25x=180+0.40x-0.25x[/tex]

[tex]240=180+0.15x[/tex]

Subtract both sides by 180

[tex]240-180=180+0.15x-180[/tex]

[tex]60=0.15x[/tex]

divide both sides by 0.15

and we get

[tex]x=400 miles/tex]............Answer

The total charge for each vehicle, a car and a minivan, is the same when 400 miles are driven.

The subject you're dealing with here is algebra, specifically, finding the point where two linear functions intersect which shows when the cost of renting the two different vehicles will be the same.

Let's use the formula for the cost of each vehicle, where C is the total cost, W is the flat weekly charge, M is the price per mile, and X is the number of miles driven:

For the car: C = $240W + $0.25M X

For the minivan: C = $180W + $0.40M X

Set these two equations equal to each other to solve for X, the number of miles driven when the two costs are equal:

$240W + $0.25M X = $180W + $0.40M X

Subtracting $180W from both sides and $0.25M X from both sides, you get:

$60W = $0.15M X

Finally, divide by $0.15M to solve for X:

X = $60W/$0.15M = 400 miles

Therefore, the total charge for each vehicle is the same when 400 miles are driven.

x=2

(2X-8.6)/2=-2.3

multiply both sides by 2 to gte rid of the denominator

2x-8.6= -4.6

add 8.6 to both sides

2x=4

x=2

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

First, multiply 2 to both sides

(2x - 8.6)/2(2) = -2.3(2)

2x - 8.6 = -4.6

Isolate the x. First, add 8.6 to both sides

2x - 8.6 (+8.6) = -4.6 (+8.6)

2x = -4.6 + 8.6

2x = 4

Next, to isolate the x, divide 2 from both sides

2x/2 = 4/2

x = 4/2

x = 2

By solving a linear equation, conclude that the measure of our angle is 55 degrees.

We know that two angles A and B are supplementary if their measures add up to 180°, then:

A + B  = 180°

And two angles are complementary if their measures add up to 90°.

A + B = 90°

Now, let's define A as our angle, B as the supplement, and C as the complement, then we can write:

A + B = 180°

A + C = 90°

We know that B is 20° more than 3 times the complement, then we can write:

B = 20° + 3*C

Usuing the two equations above we can rewrite:

B = 180° - A

C = 90° - A

Replacing that above, we get:

(180° - A) = 20° + 3*( 90° - A)

We need to solve this linear equation for A.

180° - A = 20° + 270° - 3*A

3*A - A = 20° + 270° - 180°

2*A = 110°

A = 110°/2 = 55°

We conclude that the measure of our angle is 55 degrees.

Answer:

Step-by-step explanation:

Let [tex] x[/tex] be the greater number and [tex] y [/tex] be the smaller number. We know that their difference is 15, so we have

[tex] x-y=15 [/tex]

Then, we have the following information: if we add twice the greater (2x) and 8 (2x+8), the result is 3 times the lesser (3y) minus four (3y-4). So, we have

[tex] 2x+8 = 3y-4 \iff 2x-3y = -12 [/tex]

So, we have the follwing system:

[tex] \begin{cases} x-y=15\\2x-3y = -12\end{cases} [/tex]

From the first equation, we can derive [tex] x = y+15 [/tex], and substitute this expression in the second equation to get

[tex] 2(y+15)-3y = -12 \iff 2y + 30 -3y = -12 \iff -y = -42 \iff y = 42 [/tex]

Substitute this value for y in the first equation to get

[tex] x-42=15 \iff x=15+42 \iff x = 57 [/tex]

Firstly, we need to write down the information given in the form of algebraic equations. We can represent our two unknown numbers, the greater and the lesser, as x and y respectively.

From the given information, we can form two equations. The first equation is from "the difference between the two numbers is 15", which gives us x - y = 15, where x is the larger number and y is the smaller one.

Also, we know that "If 8 is added to twice the greater number, the result is 4 less than 3 times the lesser number", this gives us the second equation: 2*x + 8 = 3*y - 4.

We now have a system of two equations that we can solve simultaneously:

1) x - y = 15
2) 2*x + 8 = 3*y - 4

To make it easier, let's multiply the first equation by 2, which gives us 2*x - 2*y = 30.

Now subtract the second equation (2*x + 8 = 3*y - 4) from the first (2*x - 2*y = 30), it yields: -2*y - 3*y = 30 - (-4 - 8).

This simplifies to -5y = 30 + 4 + 8, or -5*y = 42.

To get the value of y, divide by -5, therefore y = -42 / -5 = 42.

Now to find x, we can substitute y = 42 in the first equation (x - y = 15), so we get x = 42 + 15 = 57.

Hence, the greater number is 57 and the lesser number is 42.

-56mi in 4 minutes is (56mi/4) in 1 minutes = 14mi/minute.

Therefore, the submarine was 14 miles below sea level after 1 minute.

Answer:

The submarine's depth relative to sea level after the first minute is -14 miles.

Step-by-step explanation:

Consider the provided information.

Starting at sea level, a submarine descended at a constant rate to a depth of −56 mile relative to sea level in 4 minutes.

This can be written as:

[tex]-56\ miles=4\ minutes[/tex]

To find the submarine's depth relative to sea level after the first minute, divide both the sides by 4.

[tex]\frac{-56}{4}\ miles=\frac{4}{4}\ minutes[/tex]

[tex]-14\ miles=1\ minutes[/tex]

Hence, the submarine's depth relative to sea level after the first minute is -14 miles.
