Mathematics
1 answer:
fgiga [73]3 years ago
3 0

Answer:

In step by step

Step-by-step explanation:

For #1, everything is perfect.

For #2, you wrote your functions out incorrectly, but your x input and y output are correct

#3 is a little messed up.

Your function is f(x)=-3x+1. Your given x's are -3, -1, 0, 1, 2, and 3. Plug all of these in.

1. f(-3)=-3(-3)+1

  • f(-3)=9+1
  • f(-3)=1

2. f(-1)=-3(-1)+1

  • f(-1)=3+1
  • f(-1)=4

3. f(0)=-3(0)+1

  • f(0)=0+1
  • f(0)=1

4. f(1)=-3(1)+1

  • f(1)=-3+1
  • f(1)=-3

5. f(2)=-3(2)+1

  • f(2)=-6+1
  • f(2)=-5

95°<br> 6rº + 47°<br> r_ degrees
e-lub [12.9K]

Answer:

r = 8°

Step-by-step explanation:

95° = 6r° + 47° ( vertically opposite angles are equal)

6r° = 95° - 47°

6r = 48°

r = 48°/6

r = 8°

HELP ASAP!! 10 minuets left! lots of points
VLD [36.1K]

Answer:

130 yd^2

Step-by-step explanation:

First we find the area of the triangle

A = 1/2 b h  where b is 10 and h= 6.25

A = 1/2 (10) * 6.25

   = 31.25 yd^2

Then we find the area of rectangle A

A = l*w  where l is 10 and w = (7.5-2.5) = 5

A = 10 * 5

   = 50 yd^2

Then we find the area of rectangle B

A = l*w  where l is 6.5 and w = 7.5

A = 6.5 * 7.5

   = 48.75 yd^2

The total area is found by adding them together

A triangle + rectangle A  + rectangle B

31.25+50 + 48.75

130 yd^2

Nine more than seven times a number, n, gives the same value as one more than the square of the number. Write an equation and so

Equality Properties

<u>Algebra I</u>

  • Factoring
  • Solving quadratics

Step-by-step explanation:

<u>Step 1: Set up Equation</u>

"Nine more" is + 9

"Seven times a number" is 7n

"One more" is + 1

"Square of the [same] number" is n²

7n + 9 = n² + 1

<u>Step 2: Solve for </u><em><u>n</u></em>

  1. Subtract 7n on both sides:                    9 = n² - 7n + 1
  2. Subtract 9 on both sides:                      0 = n² - 7n - 8
  3. Factor quadratic:                                    0 = (n - 8)(n + 1)
  4. Solve roots:                                            n = -1, 8

Sharon is planning a holiday for 4 people for 7 days.
sineoko [7]

Answer:

£ 3600

Step-by-step explanation:

Each PERSON cost:

Travel cost 130 (assume for whole 7 days since per day is not written)

Hotel 60 per day (so 7 days = 60 * 7 = 420)

Money Spend 350 (assume for whole 7 days since per day is not written)

-------------------------------------------------------------------------------------------------------------

Now, that sums to:

130 + 420 + 350 = £900 [each person for whole 7 days]

Now, there are 4 person, so total cost of whole group (4 persons):

900 * 4 = <u>£ 3600</u>
