f the line passing through the points (1, a) and (5, −2) is parallel to the line passing through the points (2, 8) and (−5, a +
aleksandrvk [35]

Answer:

a=-6

Step-by-step explanation:

Line 1:  (1, a) and (5, −2)

slope of the   line is

slope = \frac{y_2-y_1}{x_2-x_1} =\frac{-2-a}{5-1} =\frac{-2-a}{4}

Line 2:  (2, 8) and (−5, a + 7)

slope of the   line is

slope = \frac{y_2-y_1}{x_2-x_1} =\frac{a+7-8}{-5-2} =\frac{a-1}{-7}

when the lines are parallel then slopes are equal

\frac{a-1}{-7} =\frac{-2-a}{4}

cross multiply it

4(a-1)=-7(-2-a)

4a-4=14+7a

subtract 4a from both sides

-4=14+3a

-18=+3a

divide both sides by 3

a=-6

The points (4,1) and (x,-6) lie on the same line. If the slope of the line is 1, what is the value of x?
bagirrra123 [75]

Answer:

x = -3

Step-by-step explanation:

Substitute the values m = 1 and from the points into the slope formula. Then solve for x.

m = \frac{y_2-y_1}{x_2-x_1}\\\\1 = \frac{1--6}{4-x}\\\\1 = \frac{7}{4-x}\\\\4-x = 7\\\\-3 = x

15 points Question
Mrac [35]

Answer:

18ft²

Step-by-step explanation:

V volume pyramid = 1/3× base area × height

V = 1/3 × B × h

24 ft³ = 1/3(12ft²)(6ft)

when V =54 ft³ h= 9ft B =?

V=1/3Bh

B=V3/h

B=(54×3)/9

B=6×3

B=18 ft²
