First, remove the parentheses
-7+2x+7=-7
Cancel the equal terms.
2x+7=0
Subtract 7
2x= -7
Divide both sides by 2
Final answer is:
X= -3.5
Your answer is D because his line needs to be slightly above +25 each time 50+25=75 so his line would be above 75
From the given the function, <span>y(t)=−t²+14t−40; the graph will be as shown below:
From the graph, it is evident that between the intervals 6</span>≤t≤8<span>:
The value of our function decreases over the given interval. Hence the answer is:
</span><span>a. The value of y(t) increases over the interval 6≤t≤7
</span>
Answer:
6150 pounds
Step-by-step explanation:
we know 1 ton = 2000 pounds
so 3 tons + 150 pounds
= 3 x 2000 + 150
= 6000 + 150
= 6150 pounds
