In the figure, P is the starting point of Perter.

Q is the point of his first right turn which is 5m from the starting point.

R is the next point of his right turn which is again 5m from P.

T is another right turn which is 20m from R.

U is the stop point which is 5m from T.

It is clear that P is the starting point and U is the stop point.

We need to find PU.

From figure, PU = ST but ST = RT - RS and RS = QP

Therefore, PU = RT - QP

PU = 20 - 5 = 15m.

Hence, he is 15m far from the starting point.

What is the point-slope form of a line that has a slope of 3 and passes through the point (-1, 4)?
Keith_Richards [23]

Answer:

Step-by-step explanation:

hello :

the point-slope formula is :  

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

in this exercice :  x_1 = -1            y_1 = 4             m = 3 

so : y - 4 = 3(x +1)   ...an equation for this line .

Solve x∕4 + y∕3 = 1 for x.
VladimirAG [237]

Answer:

D)x = 4∕3y – 4

Step-by-step explanation:

\frac{x}{4}  +  \frac{y}{3}  = 1

3x + 4y = 12

3x = 12 - 4y

x = 4 -  \frac{4}{3} y

x = 4 -  \frac{4}{3} y
