Answer:

y = 4x – 10

Step-by-step explanation:

slope formula: [tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

point-slope formula: [tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]

Note: When given two points you only need to pick one for the point-slope formula! Best to choose the positive one so you don't have to deal with the negatives!

Answer:

Step-by-step explanation:

Average speed is total distance divided by total time.

The relation between time, speed, and distance is ...

  time = distance/speed

The time to travel 5 mi at 35 mi/h is ...

  time = (5 mi)/(35 mi/h) = 1/7 h

30 seconds is (30 s)/(3600 s/h) = 1/120 h, so the total time for this trip is ...

  1/7 +1/120 = (120 +7)/840 = 127/840 hours

At 80 mph, the distance traveled in 1/120 hour is ...

  distance = speed × time = (80 mi/h)(120 h) = 2/3 mi

So, the total distance traveled is ...

  (5 mi) +(2/3 mi) = 17/3 mi

The average speed is then ...

  speed = distance/time

  speed = (17/3 mi)/(127/840 h) = 17·840/(3·127) mi/h = 37 61/127 mi/h

The average speed is about 37.48 miles per hour.

_____

Additional comment

In order for the average speed to be 55.56 mph, the time spent at 80 mph would need to be about 7 minutes 12.6 seconds, for a distance at 80 mph of about 9.61 mi.

The withdrawing money from savings would have a negative impact on determining eligibility for a home loan.

If someone is looking for a home loan they should have money in their savings accounts. If they will withdraw the money from the saving accounts then how will they pay back their loans?

So they should not withdraw money and save as much as they can so that they can easily pay back their loans.

Thus withdrawing money from savings would have a negative impact on determining eligibility for a home loan.

Answer:

(-3, 4)

Step-by-step explanation:

First, substitute y=-2x-2. We have 3(-2x-2)=9-x ---> -6x-6=9-x Then isolate the x. -5x=15 Simplify, we have x=-3. Then we can input this x-value back into one of the equations. We have 3y=9--3 ---> 3y=12 ---> y=4. So the solution to this system is (-3, 4).

A rotational symmetry implies that the shape remains the same when rotated

Justine's claim is correct

The angle of rotational symmetry is calculated as:

[tex]\theta = \frac{360}n[/tex]

Where n represents the number of sides.

From the complete question, the shape is a regular hexagon.

This means that n = 6.

So, we have:

[tex]\theta = \frac{360}6[/tex]

Divide

[tex]n = 60[/tex]

Other angles of rotational symmetry are:

[tex]n = 60, 120, 180, 240.....[/tex]

120 degrees is part of the list of possible angles of rotational symmetry.

Hence, Justine's claim is correct

The volume of the dilated Prism B is about 10 31/32 ft³

An equation is an expression that shows the relationship between two or more numbers and variables.

The height of Prism A is 6 1/2 ft, and The height of Prism B is 3 1/4 ft.

The dilation factor = 3 1/4 ft. ÷ 6 1/2 ft = 0.5

Volume is the product of three sides.

The volume of prism B = Volume of prism A * (dilation factor)³ = 87 3/4 ft³ * (0.5)³ = 10 31/32 ft³

The volume of the dilated Prism B is about 10 31/32 ft³

Lee purchased Tshirts for 15.50 each. The tot bill was $124. When x is the number of T shirts, which equation can be used to find the total number of Tshirts Lee purchased.

15.50=124x

124=15.50/x

x/124=15.50

____________________________

Let the number of T-shirts be x

then,

ATQ,

$15.50x = $124

x = $124/$15.50

x = 8

Hence , Lee purchased 8 Tshirts

The sum of the numbers expressed in scientific notations is given by: Option B:  [tex]6.82 \times 10^{12}[/tex]

The number is written in the form [tex]a \times 10^b[/tex]  where we have [tex]1 \leq a < 10[/tex]

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

Scientific notations have some of the profits as:

The given expression is:

[tex](3.1 \times 10^5) \times (2.2 \times 10^7)[/tex]

Evaluating the multiplication, we get:

[tex]3.1 \times 2.2 \times 10^5 \times 10^7 = 6.82 \times 10^{5 +7} = 6.82 \times 10^{12}[/tex]

It is because of exponent rule that [tex]a^b \times a^c = a^{b+c}[/tex], and because of commutative property of addition.

Thus, the sum of the numbers expressed in scientific notations is given by: Option B:  [tex]6.82 \times 10^{12}[/tex]

Step 2: Divide 1500 by 100.

Step 3: Subtract 15 from 50.

Answer:

35 dollars.

Step-by-step explanation:

The easiest way of calculating discount is, in this case to multiply the normal price is $50 by 30 then divide it by 100. So, the discount is equal to $15. To calculate the sales price, simply deduct the discount of $15 from the original price $50 then get $35 as the sales price.

Set two equations equal to each other

2x -16 = x+2

x = 18

Answer:

18

Step-by-step explanation:

Make the two equations to each other by subbing out the y

2x - 16 = x + 2

Move the like terms to one side

Subtract x from both sides

2x - 16 = x + 2

-x          -x

x - 16 = 2

Add 16 to both sides

x - 16 = 2

 + 16   + 16

x = 18

X will have to be 18 for these equations to be true.

Step-by-step explanation:

We will use the Tao function for our use. If there are 4 factors of a number then Tao function has a value of 4.

According to the Tao function, (a1 + 1)(a2 + 1).....(an + 1) = 4. So, by comparison We have two cases.

Case 1: a1 + 1 = 4

So, in that case a1 = 3 and we see there are two cubes less than 50.

Case 2: a1 + 1 = 2, a2 + 1 = 2

So, a1 = 1 and a2 = 1. Thus, it's a pure multiple of linear primes. And we notice there are 13 such numbers.
