Solve the formula for the indicated variable. T(r+s)=rs, for r (Simplify your answer.)

yaroslaw [1]

Answer:

$R = \frac{-TS}{(T-S)}$

Step-by-step explanation:

First, distribute all terms

$T(R+S) =RS\\TR + TS =RS$

Get all terms with R onto the same side

$TR + TS = RS\\TR - RS = -TS$

Factor out the R

$R(T-S)=-TS$

Divide by (T-S) to isolate R

$R = \frac{-TS}{(T-S)}$

A construction crew built 9 3/4 miles of road in 4 1/2 days. What is the unit rate in miles per day

Oxana [17]

Answer:

2⅙ miles per day

Step-by-step explanation:

Miles : Days

39/4 = 9¾ : 4½ = 9/2

X : 1

39/4 ÷ 9/2 = X/1

39/4 × 2/9 = X

13/6 = X

Write in slope-intercept form an equation of the line that passes through the given points. (-1, -1) (1, 5)

PSYCHO15rus [73]

<h2>Answer:</h2>

Step 1: We need to find the slope (or m) FIRST using slope formula*.

$m = \frac{5 - (-1)}{1 - (-1)}\\\\m = \frac{6}{2} = 3$

m = 3

Step 2: Now we find the y-intercept (or b) using the slope-intercept formula**, ONE of the 2 points given, and the slope we just found.

$5 = 3(1) + b\\\\5 = 3 + b\\\\2 = b$

b = 2

Step 3: Now we put it all together we get our equation in slope-intercept form**.

$y = 3x + 2$

**Slope-intercept form: $y = mx + b$

*Slope formula: $m = \frac{y_2 - y_1}{x_2 - x_1}$
