First you should round the numbers that you are multiplying so.
56 ---> 60
27---> 30
You know that 5 and higher you'll round up.
4 and below you'll round down.
5(x - 4) = 12 - 3x
5x - 20 = 12 - 3x
2x - 20 = 12
2x = -8
x = -4
Answer:
What are the answer choices? I would help but you didn't attach or write them.
Step-by-step explanation:
In a graph, "y" axis is the vertical axis and the blue curve is your function "f(x)". So, on the blue curve, trace and mark the place that is the highest in the given window. Notice that when "x" axis (the horizontal one) is π, the blue curve reaches its highest point,
For <span>h(x)=2cos(x)+1</span>, remember that the maximum value for <span>cos(x)</span> is "1". So, the maximum value for<span>h(x)=2(1)+1<span>=3</span></span>
