use substitution to solve the system of equations. Write the solution as an ordered pair.
x + 2y = 14
y = 3x - 14

Answers

Answer 1

Answer:

Step-by-step explanation:

x + 2(3x - 14) = 14

x + 6x - 28 = 14

7x - 28 = 14

7x = 42

x = 6

y = 3(6) - 14

y = 18 - 14

y = 4

(6,4)

Step-by-step explanation:

Solve for 1/2 of the kite first. The formula for area of a triangle is 1/2 times base times height. The base is 6.8 because you add 5.2 and 1.6. The height is 2.5. Multiply 6.8 times 2.5 to get 17. 17 times 1/2 is 8.5. The other half also has the area of 8.5. Add 8.5 + 8.5 to get 17.

Hope it helps and is correct!

Find the slope of the line passing through the points (-9,4) (8,4)

Answers

Answer:

slope = 0  

Step-by-step explanation:

1) Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to solve for the slope. Use the x and y values of the given points, substitute them into the formula, and solve like so:

[tex]m = \frac{(4)-(4)}{(8)-(-9)} \\m = \frac{4-4}{8+9} \\m = \frac{0}{17} \\m = 0[/tex]

Thus, the slope is 0.

Find the value of x such that the data set has the given mean
100, 123, 105, 115, 110, x; mean 120

x=

Answers

The formula for mean is

all numbers added / how many numbers there are

Counting x, we have 6 terms.

(100 + 123 + 105 + 115 + 110 + x) / 6 = 120

Get rid of the denominator by multiplying 120 times 6.

100 + 123 + 105 + 115 + 110 + x = 720

Now, subtract everything on the left from 720 and isolate x.

100 + 123 + 105 + 115 + 110 = 553

720 - 553 = 167

x = 167

X is equal to 167 I think
