Answer:
15.75
Step-by-step explanation:
Given function is
Consider the functionj
In the given graph, the point at 0 is (0,-3)
Hence the function corresponding to the given graph is
Hence the answer is C. since x=0, then
Answer:
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.
The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}
Answer:
Step-by-step explanation:
Given
Required
Determine the roots
To get the root of the function, then f(b) must be 0;
i.e. f(b) = 0
So, the expression becomes
Add 75 to both sides
Take square roots of both sides
Reorder
Expand 75 as a product of 25 and 3
Split the expression
The options are not clear enough; however the roots of the equation are
Percent is pars out of 100
40%=40/100=4/10=0.4
'of' means multiply
0.4 times something=56
divide both sides by 0.4
something=140
th enumber is 140
