Answer:

a) = Slope of line AB = 1/2

<h2><em><u>Perpendicular = -2</u></em></h2>

Step-by-step explanation:

a) When it is perpendicular the answer will be positive if the initial value is negative. If it is a whole number, then the perpendicular number is going to be a fraction. The opposite applies.

b) Slope = -2x

intercept = ?

y = -2x + b

0 = -6 + b

+6 +6

b = 6

A fisherman can row upstream at 5mph and downstream at 10mph he started rowing upstream until he got tired and then rowed downst

AlekseyPX

We have been given that the upstream speed is $5 mph$ and the down stream speed is $10mph$ .

Let the fisherman traveled a distance of x miles.

The total time of the trip is 6 hours.

Relations between speed (s), time (t) and distance (d) is $s = \frac{d}{t}$

Hence, $t= \frac{d}{s}$

Time upstream + time downstream = 6

$\frac{x}{5} +\frac{x}{10} =6$

lcm = 10

$\frac{2x+x}{10} =6$

=> $\frac{3x}{10} =6$

Cross multiplying, $3x= 60$

x = 20 miles .. Answer.

PLS HELPPPP <br><br> 14. IF m1 = (x + 13)°<br> mz2 = 39° AND<br> mz3 = (5x + 4)º.<br> SOLVE FOR X.

forsale [732]

Answer: x=12

Step-by-step explanation:

$m\angle1=(x+13)^0 \ \ \ \ \ m\angle2=39^0\ \ \ \ m\angle3=(5x+4)^0\\$

The sum of the angles of the triangle is 180°:

$(x+13)+39+(180-(5x+4))=180\\\\x+13+39+180-5x-4=180\\\\-4x+48=0\\\\-4x+48+4x=0+4x\\\\48=4x$

Divide both parts of the equation by 4:

$12=x\\\\Thus,\ x=12$

In the figure, angle K measures 45 degrees. What is the measurement of angle C?

Delvig [45]

It is 45 because the triangle should be 180 degree and if K is 45 then J should be 45, too. We all know that the right triangle is 90 degree, so we add angle J and G, it is 135. Lastly, you subtract 180- 135=45.
