Answer:

y=-4x+7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-3)/(2-1)

m=-4/1

m=-4

y-y1=m(x-x1)

y-3=-4(x-1)

y=-4x+4+3

y=-4x+7

Answer:

There are 12 apples in total.

Step-by-step explanation:

If Anne gave Ben 6 apples then heres how:

2:3 subrtact 6 apples = 1:3

6 apples x 2 = 12 apples =

2 ÷ 2 = 1

Hence, your answer is double 6 which is 12 apples.

Please find attached the image of the quadrilateral TRAM after a rotation of -90 degrees, created with MS Excel

Step-by-step explanation:

The given coordinates of the vertices of the quadrilateral TRAM are;

T(-5, 1), R(-7, 7), A(-1, 7), M(-5, 4)

By a rotation of -90 degrees = Rotation of 90 degrees clockwise, we get;

The coordinates of the preimage before rotation = (x, y)

The coordinates of the image after rotation = (y, -x)

Therefore, we get for the the quadrilateral T'R'A'M', by rotating TRAM -90 degrees as follows;

T(-5, 1) → T'(1, 5)

R(-7, 7) → R'(7, 7)

A(-1, 7) → A'(7, 1)

M(-5, 4) → M'(4, 5)

The image of TRAM after -90 degrees rotation is created by plotting the derived points of the quadrilateral T'R'A'M' on MS Excel and joining the corresponding points as presented in the attached diagram.

Answer:

8994.16

Step-by-step explanation:

formula:

[tex]PV(1+\frac{i}{n})^{nt}\\7500(1+\frac{.0365}{4})^{5*4}\\8994.16[/tex]

Answer:

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

P = $7500

r = 3.65% = .0365

n = 4 (because compounded quartely)

t = 5years

[tex]A = 7500(1+\frac{0.0365}{4})^{4*5}\\\\[/tex]

    =[tex]7500(1+0.09125)^{20} = 8994.16[/tex]

Answer = $8994.16

Answer:

45.24 cm

Step-by-step explanation:

C = pi(d)

Since we have our radius, we can find our diameter. To get the diameter, we multiply the radius by 2. In this case; 7.2 cm.

7.2(2) = 14.4

Then, we multiply the diameter by pi.

(pi)(14.4) = 45.238

45.238 ---> 45.24

Hello if I know the answers to your math questions I'll answer if there already posted I'll check your profile if not please post them thank you!

Answer:

no solution

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

- 10 | 5x + 5 | = 100 ( divide both sides by - 10 )

| 5x + 5 | = - 10

The absolute value cannot be negative thus the equation has no solution

Answer:

$2,250

Step-by-step explanation:

5% of 15,000 is 750. If we multiply 750 by the number of terms, 3, we get an answer of $2,250.

Answer:

$2,250

Step-by-step explanation:

Use the simple interest formula i = prt.  Here the principal, p, is $15,000 and the interest rate, r, is 0.05.  Then:

i = ($15,000)(0.05)(3) = $2,250

Answer:

y=1/4x-4

Step-by-step explanation:

slope is 1/4 and the y intercept is -4

Answer: the distance for d is about  5.8 units

Step-by-step explanation:

Use the pythagorean theorem. a^2 + b^2+= c^2 . in this case, c^2 is the distance for d.

5^2 + 3^2= d^2

25+9= d^2

34= d^2

square both sides and d is approximately 5.818

11 + 5 = 15 + 11

This is false

Answer:

  a square 175 m on a side

Step-by-step explanation:

Let x and y represent the sides of the rectangle. Then the perimeter is ...

  P = 2(x + y) = 700

  x + y = 350 . . . . . . . divide by 2

  y = 350 -x . . . . . . . . subtract x

The area of the fenced field is ...

  A = xy

  A = x(350 -x)

This is a quadratic function that has zeros at x = 0 and x = 350. The axis of symmetry is x = (0 +350)/2 = 175. The vertex (maximum area) is on the axis of symmetry, so corresponds to x = 175. The y-value there is ...

  y = 350 -x = 350 -175 = 175

That is, the maximum area will be obtained when the fenced area is a square. Each side of the square is 175 m, which is 1/4 of the total length of the fence.

The dimensions of the space are 175 m by 175 m.

The centre and radius of the circle is (2, 3) and 6 units respectively

The standard equation of a circle is expressed as:

(x – a)² + (y – b)² = r²

where:

Given the equation

(x – 2)² + (y – 3)² = 36

Compare

(a, b) = (2, 3)

r² = 36

r = 6 units

Hence the centre and radius of the circle is (2, 3) and 6 units respectively

Answer:

Step-by-step explanation:

Common ratios are found by either multiplying the same number in to get to the next number in the sequence, or by dividing out the same number in to go the next number in the sequence. Multiply or divide, NOT add or subtract! Be careful! Obiviously, our numbers are going down, so we are dividing out a specific number as opposed to multiplying one in. To get from 18 to 6, we have to divide by 3; however, the 6 is negative, so we have to divide by -3. To determine if we are correct, divide -6 by -3 and see if that result is the next one in line. -6 divided by -3 is 2. So we are correct, and the common ratio is -3.

Answer:

6.1 m

Step-by-step explanation:

Always draw a diagram! And now pythagorean theorem. a^2 + b^2 = c^2

Substitution:

a^2 + 2.8^2 = 6.7^2

a^2 + 7.84 = 44.89

a^2 = 37.05

a = 6.086...

Rounding up to one decimal point, thats 6.1 m

Answer:

m=-2/3

Answer:

18 minutes

Step-by-step explanation:

Given that the time (T) varies directly as the number of spectators (S) and varies inversely as number of open exits (E).

Hence:

T ∝ S; T ∝ 1 / E

Let k be the constant of proportionality. This gives:

T = kS / E

when T = 12 minutes, S = 20000, E = 20. Hence:

12 = k(20000) / 20

20000k = 240

k = 12 / 1000

This gives:

T = [tex]\frac{12}{1000}(\frac{S}{E} )[/tex]

When  S = 36000, E = 24, we are to calculate the time (T):

[tex]T=\frac{12}{1000} (\frac{36000}{24} )=18\\[/tex]

T = 18 minutes
