8 is not in the solution set

Step-by-step explanation:

Given, -y + 7 < -4

To find out if 8 is in the solution set, substitute y = 8 in the inequality and solve to see if the statement would be true.

Thus:

-8 + 7 < -4

-1 < -4

This -1 is less than -4. This is actually not TRUE. -1 is rather greater than -4.

Therefore, 8 is not in the solution set.

are 30°and 45°respectively, find the distance
between the boat

Answers

Step-by-step explanation:

Height of tower - 80m

Distance between foot of tower and boat 1 = x

Distance between boat 1 and boat 2 =y

Tan 45 = 1 = 80/x

Easton is driving to a concert and needs to pay for parking. There is an
automatic fee of $8 just to enter the parking lot, and when he leaves the lot,
he will have to pay an additional $3 for every hour he had his car in the lot.
How much total money would Easton have to pay for parking if he left his car
in the lot for 2 hours? How much would Easton have to pay if he left his car in
the lot for t hours?

Answers

Answer:

If he left the car in the lot for 2 hours, he would have to pay 14 dollars. if he left it for "t" hours, he would have to pay 11 + 3t dollars

Step-by-step explanation:

Think of it like this: "a" represents the total amount of money Easton will spend, t represents time in hours. $11 + $3*t = a

For 2 hours he would pay $14
8+(3*2) =14

For t hours
8+ 3t

Over a two hour time period a snail moved 50 inches. How far is this in yards? Write your answer as a whole number or a mixed number in simplest form. Include the correct unit in your answer.

Answers

Answer:

1.3 yards

Step-by-step explanation:

Answer:

1 7/18 yards or 1 14/36 yards.

Step-by-step explanation:

There are 36 inches in a yard, so you divide 50 by 36.

You get a variety of answers depending on what form you want it in:

1 yard 1 foot and 2 inches.

1 yard and 14 inches.

These two answers take two forms as fractions of 36:

1 14/36 yards

or simplified: 1 7/18 yards.

Answers

Answer:

a) not proportional

b) proportional; k = [tex]-\frac{3}{5}[/tex]

Step-by-step explanation:

a) for any proportional equation, the line must pass through the origin. The equation in a) is y = 4x + 1, and the '+1' is the y-intercept. This means that the line does not pass through the origin, so x and y cannot increase by the same amount (i.e. they are not proportional).

Another way to determine this is is to use the y = kx base. If you have an equation that fits that it's likely proportional.

Here, if the equation was only y = 4x then it'd be proportional because u can see that k = 4. This is not the equation though, and the 4x + 1 doesn't fit to the y = kx formula so it can't be proportional.

b) straight away you can see that there's no 'c' term (y = mx + c) which means the y-intercept is 0, so the line passes through the origin. While this does not immediately mean the line is proportional, you can make sure that it is by checking it fits with the y = kx equation.

y = -(3/5)x fits with y = kx, with k being -3/5

How much net work is required to accelerate a 1000 kg from 20 m/s to 30
m/s?

Answers

Answer:

Work= force(F) * distance (s)

weight is a force and so

F=weight=mass *acceleration due to gravity

=1000*10=10000N

S=?

To find s,

F= ma

a=F/m=10000/10

a=10m/s²

Using Newton's third equation of motion

v²= u²+2as

30²= 20²+2*10*s

900–400=20s

500=20s

s=500/20= 25m

Work =F*s

Work=10000*25

Work= 250000J or 250KJ

Gwen takes out a loan of $400 to pay for an online course. Flat rate interest is charged at 8% p.a

If she repays the loan in 3
months, how much interest does she pay in total?

Answers

We know, 1 year = 12 month.

So, 3 month = 3/12 = 0.25 year.

Now, principle amount, P = $400 .

Rate is, r = 8% = 0.08

Time period, t = 0.25 year.

Now, Interest is given by :

I = P × r × t

I = $( 400 × 0.08 × 0.25 )

I = $8

Therefore, she will pay $8 interest in total.

Is x = -4 a solution to these equations? Show your work and write YES or NO.

1. 3(2x-4) = -36
2. 5x - 6x - x = 18
3. 5 - 2(3x - 1) = 31

Answers

Answer:

1. Yes

2. No

3. Yes

Step-by-step explanation:

We have three equations where x is equal to -4. We are then asked if -4 are a solution to these equations.

To solve we need to substitute the x in every equation for -4. Start :

3(2(-4) - 4) = -36

3(-8 - 4) = -36

-24 - 12 = -36

Therefore -4 is a solution.

5(-4) - 6(-4) - (-4) = 18

-20 + 24 + 4 = 18

4 + 4 = 18

8 ≠ 18

Therefore -4 is not a solution.

5 - 2(3(-4) - 1) = 31

5 - 2(-12 - 1) = 31

5 - 2(-13) = 31

5 + 26 = 31

Therefore -4 is a solution.
