1. (-6,8)
2. (6,8)
3. (-6,-8)
4 .(6,-8)

Answers

Answer 1

Answer:

3.(-6,-8)

Step-by-step explanation:

y=x-2

2x+4=y

x-2=2x+4

x=2x+6

-x=6

x=-6

y=-6-2

y=-8

Answer 2

Step 1: Wherever you see a y in the equation: 2x + 4 = y insert x - 2

2x + 4 = x - 2

Step 2: Combine like terms

x's go with x's. To do this subtract the x from the right side to both sides

(2x - x) + 4 = (x - x) - 2

x + 4 = 0x - 2

x + 4 = -2

Normal numbers go with normal numbers (4 and -2). Bring the 4 to the right side by subtracting it to both sides

x + (4 - 4) = -2 - 4

x + 0 = -6

x = -6

Step 3: To solve y put -6 where you see an x in the equation: y = 2x + 4

y = 2(-6) + 4

y = -12 + 4

y = -8

(-6,-8)

The museum has tours every 20
minutes and a video to watch
every 15 minutes. Both the video
and tour start at 10:00 a.m. What
is the next time they will both be
starting at the same time?

Answers

Final answer:

The next time a museum tour and video both start at the same time after 10:00 a.m. is at 11:00 a.m., as that is when their intervals (every 20 minutes for tours and every 15 minutes for videos) have their Least Common Multiple.

Explanation:

The question is about finding the next time a museum tour and a video both start at the same time after 10:00 a.m. The tours start every 20 minutes and the videos start every 15 minutes. To find the next common start time, we need to calculate the Least Common Multiple (LCM) of 20 and 15 which is the smallest number that both 20 and 15 can divide into without leaving a remainder.

Multiples of 20 are 20, 40, 60, 80, 100, ...

Multiples of 15 are 15, 30, 45, 60, 75, ...

The first common multiple of the two intervals is 60 minutes. Therefore, since both the tour and the video start at the same time (10:00 a.m.), the next time they will both start together will be 60 minutes later, which is at 11:00 a.m.

A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle. The python is 2.6 pie meters long. What is the radius r of the circle that the python forms?

Answers

Answer:

r = 1.3 meters  

Step-by-step explanation:

A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.

A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.  

The python is 2.6 pi (2.6π) meters long.

What is the radius r of the circle that the python forms?

Now we have: C = π d, or (with d = 2 r):  C = 2 π r.

Changing that around: r = C / 2 π

So with our value of C = 2.6π meters, that gives us:

r = 2.6π/2π = 2.6/2, so r = 1.3 meters

Answers

ANSWER

D. [tex]126 {in}^{3} [/tex]

EXPLANATION

The formula for calculating the volume of a rectangular prism is

[tex]Volume =lbh[/tex]

The given rectangular prism has

length,

[tex]l = 8 \: in[/tex]

The width is

[tex]w = 4 \frac{1}{2} in[/tex]

and the height is

[tex]h = 3\frac{1}{2} in[/tex]

We substitute the values into the formula to obtain;

[tex]Volume =8 \times 4 \frac{1}{2} \times 3 \frac{1}{2} [/tex]

[tex]Volume =8 \times 4.5 \times 3.5[/tex]

[tex]Volume =126 {in}^{3} [/tex]

Answer:

The correct answer is option D.  126 in³

Step-by-step explanation:

Formula:-

Volume of cuboid - lbh

l - Length of cuboid

b - Breadth of cuboid

h - Height of cuboid

To find the volume of prism

Here rectangular prism is like a cuboid.

l = 8 in, b = 4 1/2 = 9/2 and h = 3 1/2 = 7/2

Volume = lbh

     = 8 * 9/2 * 7/2 = 126 in³

Therefore the correct answer is option D.  126 in³

what is the solution to the system of equations ? y=5x+2 3x=-y+10

Answers

Answer:

Solution is (1,7).

Step-by-step explanation:

We need to find the solution of the system of following equations.

y= 5x + 2        eq(1)

3x = -y +10      eq(2)

We will solve the equations using Substitution method to find the values of x and y

we put value of y from eq (1) into eq (2), The eq(2) will be:

3x = - (5x + 2) + 10

3x = -5x -2 +10

3x+5x = -2+10

8x = 8

x= 1

Now, putting value of z in eq(1) to find value of y

y = 5x +2

y = 5(1) + 2

y = 5+2

y = 7

So, Solution is (1,7).

A person invest $1200 in an account that earns 2% interest compound quarterly. Find when the value of the investment reaches $1500.00

Formula

A=P(1+r/m)mt

Answers

Answer:

After 11 years the value of the investment reaches $1500.00

.

Step-by-step explanation:

The formula used for finding time (when the value reaches certain amount) is:

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

where A= Future VAlue

P= Principal Value

r= rate of interest (in decimal)

n= no of times investment is compounded

t= time

Putting the values given and finding Time t,

A= $1500

P= $1200

r= 2% or 0.02

n= 4 (compound quarterly)

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

[tex]1500= 1200(1+\frac{0.02}{4})^{4t}[/tex]

Dividing both sides by 1200 and solving 0.02/4 = 0.005

[tex]1.25= (1+0.005)^{4t}[/tex]

[tex]1.25= (1.005)^{4t}[/tex]

Since t is in power we take the logarithm ln on both sides.

The rule of logarithm says that the exponent can be multiplied with the base when taking log

[tex]\ln1.25=ln( 1.005)^{4t}\\\ln1.25=4t * ln( 1.005)\\0.22 = 4t * 0.005\\Solving\,\,\\\frac{0.22}{4*0.005} = t\\=> t= 11\, years[/tex]

-109

Step-by-step explanation:

Arithmetic sequence formula:

an = a1  + d(n - 1) where d = -4 and a1 = 19

so

a(33) = 19 - 4(33-1)

a(33) = 19  - 4(32)

a(33) = 19 - 128

a(33) = -109

The missing term : -109

Answer:

-109

Step-by-step explanation:

As x changes from 1 to 2, 2 to 3, and 3 to 4, each change in x is 1. The  corresponding changes in y from 19 to 15, from 15 to 11, and from 11 to 7, are each a change of -4 in y. For each change of 1 in x, the corresponding change in y is -4. From 4 to 33 in x, the change is 33 - 4 = 29. The corresponding change in y is 29 * (-4) = -116.

7 + (-116) = -109

What is the equation in slope-intercept form of point (1,10) and has a slope of 7?

Given:

A line that includes the point (1,10) and has a slope of 7.

Find:

The equation in slope-intercept form.

Solution:

We will use y = mx+b where m = slope and b = y-intercept.

y = mx+b

Now, putting (1,10) in the place of x and y and slope as 7, we get;

10 = 7*1 + b

b = 10-7

b=3

So, the y-intercept is 3.

Now, putting the y-intercept in the slope-intercept equation, we get;

y = 7x+3

Hence, the equation in slope-intercept form is y=7x+3.

So members who preferred black and white short sleeved T- shirts = [tex]\frac{62}{2}[/tex] = 31 each

What is Kyle’s fixed monthly salary in dollars?

Answer:

$900

Step-by-step explanation:

Let the fixed salary be x and the commission be y, then as per given, the earnings:

10000y + x = 135015000y + x = 1575

Subtract the first equation from the second:

15000y - 10000y = 1575 -13505000y = 225

then

10000y =2*5000y = 2*225 = 450

Using the first equation:

x = 1350 - 450 = 900

So the fixed salary is $900

Kia buys 2 Cartons of Vanilla Ice Cream And 6 Cartons of Chocolate Ice Cream. Each carton contains 32 ounces of ice cream. She serves 4 ounces of ice cream in each bowl. What is the greatest number of bowels of ice cream that Kia can serve? ​

Answers

64 bowls because if you Multiply eight times 32. You would get 256 and then you divide that into four and would get 64 which is your answering

the greatest number of bowls of ice cream Kia can serve is 64.

The student wishes to determine the greatest number of bowls of ice cream that can be served given certain quantities of ice cream and serving sizes. To solve this, we first calculate the total amount of ice cream by adding the quantities of vanilla and chocolate ice cream. Kia bought 2 cartons of vanilla and 6 cartons of chocolate, each containing 32 ounces. Thus, the total amount of ice cream is (2 + 6) × 32 ounces. Each bowl served contains 4 ounces of ice cream. To find the number of bowls, we divide the total ounces of ice cream by the ounces per bowl. This yields (8 × 32) ÷ 4, which calculates to 64 bowls. Therefore, the greatest number of bowls of ice cream Kia can serve is 64.
