A line passes through the point (3,4) and has a slope of 7. Write an equation for this line
Dmitry [639]

Answer:

y = 7x - 17

Step-by-step explanation:

If you graph the coordinate (3,4) and then apply the slope (7 up / 1 down) , you will end up passing through the point (0,-17) on the y line. The point the line passes on the y line would be the y intercept.

Once you have all the necessary information, you put it into a y=mx+b form. m being the rate or slope, and b being the y-intercept.

You and your friend are having a race, but since you are faster than him, you decide to give him a head start. He starts 10m in
Diano4ka-milaya [45]

Answer:

20 seconds

Step-by-step explanation:

Your friend starts 10 meters in front of the starting line.

You start from the starting line.

You run at 6 meters/ second.

Your friend runs at 5.5 meters/second.

You and your friend will be at the same distance from the starting line only when you are able to catch your friend.

The relative speed between you two is the difference in your speed and your friend's speed that is:

6-5.5=0.5m/s

So to cover 10 meters of separation at the speed of 0.5 meter/second it will take:

t=\frac{10}{0.5}= \frac{100}{5}=20s

So it will take 20 seconds for you and your friend to be at the same distance from the starting line.

Which of these ordered triples indicates where the plane cuts the x-axis for this equation? 7x +2y +3z =42 A. (14,0,0) B. (7,0,0
pickupchik [31]
My answer is: D. <span>(6,0,0)

Given: 
</span><span> 7x +2y +3z =42

I assumed that the format in the given choices is (x,y,z). So, I substituted each number to its corresponding variable.

A. </span>(14,0,0)  → 7(14) +2(0) +3(0) = 42 → 98 + 0 + 0 ≠ 42  NOT THE ANSWER<span>
B. (7,0,0) </span>→ 7(7) +2(0) +3(0) = 42 → 49 + 0 + 0 ≠ 42 NOT THE ANSWER<span>
C. (21,0,0) </span>→ 7(21) +2(0) +3(0) = 42 → 147 + 0 + 0 ≠ 42 NOT THE ANSWER<span>
D. (6,0,0) </span>→ 7(6) +2(0) +3(0) = 42 → 42 + 0 + 0 = 42 CORRECT ANSWER.


<span>The ordered triples indicated where the plane cuts the x-axis for this equation is D. (6,0,0). </span>
