Given g(x) =
1/4(15 - x)^2
what is the value of g(7)?

Answer:

x = 4

y = 2

Step-by-step explanation:

x - y = 2

   x = 2 + y

2x + 3y = 14

  2(2 + y) + 3y = 14

  4 + 2y + 3y = 14

  4 + 5y = 14

  5y = 10

   y = 2

x - y = 2

  x - 2 = 2

  x = 4

1). ASA postulate of congruence

2). Triangles are congruent.

Answer:

[tex]\sqrt{(-3^2-6)+(7^2-4^2)}[/tex]

Step-by-step explanation:

Use the form: [tex]\sqrt{(x^2-x^1)+(y2-y1)^2[/tex]

so: [tex]\sqrt{(-3^2-6)+(7^2-4^2)}[/tex]

By the distance formula,

[tex]d = \sqrt{( x_2 - x_1) {}^{2} + (y_2 - y_1 {)}^{2} }[/tex]

Here,

[tex]x_1 = 4[/tex]

[tex]y_1 = 6[/tex]

[tex]x_2 = 7[/tex]

[tex]y_2 = - 3[/tex]

Hence,

[tex]d = \sqrt{( {7 - 4)}^{2} + {( - 3 - 6)}^{2} } [/tex]

[tex]d = \sqrt{ {3}^{2} + ( - {9)}^{2} } [/tex]

[tex]d = \sqrt{9 + 81} [/tex]

[tex]d = \sqrt{90} [/tex]

Hmmm I got (11,6) and I did it two different ways. Are these the only answers?

Answer:

(11, 6)

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define systems

2x - 3y = 4

x + 3y = 29

Step 2: Rewrite systems

2x - 3y = 4

x = 29 - 3y

Step 3: Solve for y

Step 4: Solve for x

Step 5: Check

Graph the systems of equations to verify the solution set.

let me now if u have a questions have a nice day

and Thanks :)

-1/3(px-2) = 9

ok! so first we want to isolate x.

multiply both sides by -3/1 (this is the reciprocal of -1/3)

(px-2) = -27

px = -27 + 2

px = -25

x = -25/p

hope this helped!

Answer:

$27.36

Step-by-step explanation:

To find how much she spent you add the costs of the movie and bowling alley: 22.64

Now you subtract that from the amount of money you had to get: 27.36

Hope this helps!

Answer:

Adrian has $27.36 left.

Step-by-step explanation:

First add up the total Adrian spent!

12.45 + 10.19 = 22.64

Now subtract that amount from $50

50.00 - 22.64 = 27.36

Therefore, Adrian has $27.36 left

Answer:

100d / (s+2h)

Step-by-step explanation:

Answer:

A. Move the decimal point to the left

Step-by-step explanation:

Given that:

The scientific notation = 10⁻¹⁰

Let recall;

That the standard notation usually took the form of an inverse:

For example;

Let say 10⁻¹ will be [tex]\dfrac{1}{10}[/tex] in scientific notation;

SO, [tex]\dfrac{1}{10} = 0.1[/tex]

Now; we are given 10⁻¹⁰ as a scientific notation,

To standard notation, we get:

[tex]10^{-10} = \dfrac{1}{100}[/tex]

= 0.01

Thus, it is true to say that the decimal point will be moved to the left side when converting a number from scientific notation to standard notation if the power of 10 is  -10.

Answer:

20 and -20

20^2 = 400

(-20)^2=400 since two negative is positive

Answer:

1) Isosceles - 2 sides are the same.

2) Scalene - all the sides are different, and an oblique angle.

3) Right Triangle - it has a right angle

4) isoscele - 2 sides are the same it has acute angles.

5) Scalene - all the sides are different, and an oblique angle.

6) equilateral - all the sides and angles are the same.

Step-by-step explanation:

angle B = angle C

2.5x + 6 = 7x - 12

4.5x = 18

therefore x = 4

substituting the value of x we get answer

angle B = 16

angle C = 16

Answer: 400 calories per hour

Step-by-step explanation:

Q: Tina recorded the number of calories she burned during a bike ride. The graph shows Tina’s calories burned, y, after x hours. If Tina rode her bike at a constant rate for the first three hours, what was Tina’s average calories burned, in calories per hour, between hour 0 and hour 3?

Expalanation: It is seen from the graph that her rate of burning calories increased to 1200 in the first three hours of riding and then remained constant for the rest of the period (2 extra hours).

Her rate of calorie use therefore would be given as: (total calorie used up) / (total hours spent riding for the period of usage)

This is given as: 1200 calories / 3 hours = 400 calories per hour.

Answer:

x=19

Step-by-step explanation:

14x-43=71+8x         problem

14x=114+8x           add 43 to both sides

6x=114              subtract 8x from both sides

x=19                 divide by 6 to both sides (114/6 =19) x=19

Answer: I think it's y=2??????

Step-by-step explanation: The shop would be 0, so there would be no x. The slope is zero because the y value never changes.

Answer: 1/2 cups

Step-by-step explanation:

Given that:

Every 1/4 cup of tuna has 1/2 gram of fat

How many cups of tuna are there for every gram of fat:

Let cup of tuna for 1 gram of fat = t

Hence, If

1/4 cup of tuna = 1/2 cup of fat

t tuna = 1 cup of fat

Cross multiply :

1/2 t = (1/4 * 1)

1/2 t = 1/4

t = 1/4 ÷ 1/2

t = 1/4 * 2/1

t = 2/4

t = 1/2

Hence, 1/2 cups of tuna for every gram of fat

Answer:

y=1/2x+4

Step-by-step explanation:

change of x=2-(-4)=6

change of y=6-3=3

slope=3/6 or 1/2

y intercept=5

y=1/2x+5

Answer:

Yes, they are equivalent

Step-by-step explanation:

Case 1,

Distance = 250 miles

Time = 4 hours

Ratio = speed = distance/time

= 250 miles/4 hour

= 62.5 mph

Case 2,

Distance = 500 miles

Time = 8 hours

Ratio = speed = distance/time

= 500 miles/8 hour

= 62.5 mph

In both cases, the ratios 250 miles in 4 hours and 500 miles in 8 hours are equivalent.
