What is the slope of the line passing through the points (0, −5) and (4, 2)?

liraira [26]

$(0,-5) \\
x_1=0 \\ y_1=-5 \\ \\
(4,2) \\
x_2=4 \\ y_2=2 \\ \\
\hbox{the slope } = \frac{y_2-y_1}{x_2-x_1}=\frac{2-(-5)}{4-0}=\frac{2+5}{4}=\frac{7}{4}$

The slope is 7/4.

Solve for x. * (5x + 13) (9x - 31)

ycow [4]

Answer:

x=11

Step-by-step explanation:

5x+13=9x-31

subtract 9 from both sides.

-4x+13=-31

you want to isolate the x value so subtract 13 from both sides.

-4x=-44

now divide both sides by -4.

x=11

Make t the subject of the formula P= 3-2t ————— 4+t

Rufina [12.5K]

Answer:

$t = \frac{3 - 4p}{p + 2}$

Step-by-step explanation:

Given

$P = \frac{3 - 2t}{4 + t}$

Required

Make t the subject

$P = \frac{3 - 2t}{4 + t}$

Cross Multiply

$P * (4 + t) = 3 - 2t$

$4p + tp = 3 - 2t$

Collect Like Terms

$tp + 2t = 3 - 4p$

Factorize:

$t(p+2) = 3 - 4p$

Make t the subject

$t = \frac{3 - 4p}{p + 2}$
