The answer to this graph is (4,5)
Umm , what is this for? do you need help on anything or? lol
<span>3t – 6t + 8 – 7t = – 2
Simplify and combine Like-Terms
</span><span><span><span>3t + −6t + 8 </span>+ </span>− 7t </span>= <span>−<span>2
</span></span><span><span>(<span><span>3t+<span>−6t</span></span>+<span>−7t</span></span>) </span>+ (8) </span>= <span>−<span>2
</span></span><span><span>−10t </span>+ 8 </span>= <span>−<span>2
Subtract 8 from each side
</span></span><span><span><span>−<span>10t </span></span>+ 8 </span>− 8 </span>= <span><span>−2 </span>− <span>8</span></span>
-10t = -10
Divide each side by -10
-10t ÷ -10 = -10 ÷ -10
t = 1
You just have to plug in the value of x and y.
1) y = 2x + 10 —> y = 2(4) + 10
y = 8 + 10
y = 18
2) y = 2x - 4 —> 10 = 2x - 4
add four to both sides
14 = 2x and divide 2 by both sides and you get x = 7
A: From the graph, car B was traveling faster.
Because the line of car B is more steep than the line of car A.
B:
The lines cross at (2,80), this means that the two cars were traveling at the same distance (80 miles) at the same time (2 hours).
C:
Since the line passes through the points (0,0) and (2,80)
So the unit rate or slope is 40 mph.
The distance which car A traveled in the first four hours = 4x40= 160 mph
