Find the value of x that makes line m ll n

Mathematics
1 answer:
guapka [62]2 years ago
5 0

Answer:

See below ↓

Step-by-step explanation:

14.

  • Between two lines m ║ n, the ∦ cuts through them forming two angles
  • As it forms a line, the sum of the angles is 180°
  • 3x + 47 + x + 7 = 180
  • 4x + 54 = 180
  • 4x = 126
  • x = 126/4 = 63/2 = 31.5

15.

  • Alternate exterior angles on a transversal are equal
  • 5x = 2x + 78
  • 3x = 78
  • x = 26

4 * 3 = 12

You now have b^12.


The answer is D.

Question - Find each f(c) using synthetic substitution. f(x) =5x 5 + 10x 4 + 3x 3 + 8x 2 – 6x – 3; c = 3
SpyIntel [72]

Answer:

2157

Step-by-step explanation:

The given function is

f(x)=5x^5+10x^4+3x^3+8x^2-6x-3

We want to find f(c) when c=3.

This means the remainder when f(x) is divided by x-3

We perform the synthetic division:

    5     10      3      8       -6      -3

<u>3|         15    75    234    726    2160</u>

    5     25    78    242    720    2157

Therefore the remainder is 2157

You are right

Of the 1200 people who attended the Friday night football game, 57% were high schoolers. How many students attended the game?
Brilliant_brown [7]

Answer:

684

Step-by-step explanation:

Using proportions (equivalent ratios), we can find the number of students that make up the 57% out of the total number of people:

\frac{57}{100}=\frac{x}{1200}

Cross-multiply: 100x = (57)(1200)  or 100x = 68,400

Divide:  100x/100 = 68,400/100

Solve for x:  x = 684 students

A and B are supplementary angles. If A = 7x - 18 and B = 8x + 3, find x.
Mila [183]

Answer:

x=13

Step-by-step explanation:

Angle A and angle B are supplementary

Supplementary angles add to 180 degrees

<A + <B = 180

7x-18 + 8x+3 = 180

Combine like terms

15x -15 = 180

Add 15 to each side

15x-15 +15 = 180+15

15x = 195

Divide by 15

15x/15 =195/15

x =13
