Answer:

A) x=8 and angle ABC=115 degrees

Step-by-step explanation:

the lines are parallel, meaning the angles are congruent.

you can set up the equation (15x-5)=(10x+35) and simplify.

1. separate variable by subtracting 10x on both sides to get (5x-5)=(35)

2. add 5 on both sides to get 5x=40

3. divide both sides by 5 to get x=8

4. plug x=8 into original function (10x+35) to get (10(8)+35) which equals 115 degrees

If a car has traveled 171 miles in 3 hours at a steady pace, how far has it traveled each hour?

san4es73 [151]

Answer:

B: 57 mph=57 mph

Step-by-step explanation:

A steady pace means constant speed that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)

$v= \frac{x - xo}{t -to}$

where x is distance and t time. The subtract is final value minus initial value

We have the distance and time, then

$v= \frac{171 miles}{3 hours} = 57 mph$

A line passes through the points (2,-2) and (-6,2). The point (a.-4) is also on the line. What is the value of a?

Zigmanuir [339]

Answer:

Step-by-step explanation:

Hey there) The formula of your line is:

$-2=2k+b\\2=-6k+b\\=>4=-8k\\k=-0.5\\=> b=-2+1=-1\\=>y=-\dfrac{1}{2}x-1\\$

If point has y=-4, then:

$-4=-\dfrac{1}{2}a-1\\4=\dfrac{1}{2}a+1\\a=6$

Hope this helps) Have a nice day/night :)
