Answer:
6=69, 7=69, 8=69
Step-by-step explanation:
72
Answer:
x≤ 25.
Step-by-step explanation:
SO basically, the equation is x+-7≤ 18. What you do is you use the equation to solve for x. So, x+-7 is the same as x-7, so what you do is you add 7 from both sides to get x≤ 25.
Hope this helps:)
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
You need to find "m" and "b"
For lines to be parallel, the slopes have to be the same.
The given line's slope is 1/2, so the parallel line's slope is also 1/2.
y = 1/2x + b
To find "b", you can plug in the point (10, -5) into the equation.
y = 1/2x + b
-5 = 1/2(10) + b
-5 = 5 + b Subtract 5 on both sides to get "b" by itself
-10 = b
y = 1/2x - 10 Your answer is D (you could have just found the slope to get your answer, since all the slopes are different)
Answer:

Step-by-step explanation:
We want to find the equation of the line tangent to the graph of:

So, we will find the derivative of our equation first. Applying the chain rule, we acquire that:

Simplify:

We can factor out the denominator within the square root:

Simplify:

So, we can find the slope of the tangent line at <em>x</em> = 5/2. By substitution:

Evaluate:

We will also need the point at <em>x</em> = 5/2. Using our original equation, we acquire that:

So, a point is (5/2, π/6).
Finally, by using the point-slope form, we can write:

Distribute:

Isolate. Hence, our equation is:

Answer:
add 8 to the 12 and then multiply it by two
Step-by-step explanation:
8 + 12 = 20 * 2 = $40
