Answer: 23/18
Step-by-step explanation:
Answer:
3^2 +9
Step-by-step explanation:
Since 2+4^2 is 16+2 which is 18, you need to find the expression equivalent to 18. 25 doesn't work so eliminate that right away. 9^2=81 so that isn't right either. 2^3+9=17 so that is incorrect. Lastly, 3^2+9=18 so that is the correct answer.
Answer:

Step-by-step explanation:
Notice that the answers they give you to choose from are all lines in slope y-intercept form, it would be very simple to just find the answer finding yourself the slope and y-intercept of the line in question.
Since they give you two points
and
for the line, use them to find the slope of the line that goes through them, with the formula: 
Therefore, the slope of the line must be 
Now, find the y-intercept (b) using the general form of a line with the given slope:

Use one of the given coordinate points to request that the line passes through it. For example, through the point (-3,6) (when x = -3, y must be 6):

then the y-intercept must be 5. Therefore our line is :
which appears listed as your second choice.
Answer:
x=1
Step-by-step explanation:
To solve this question we will have to open the bracket first
So let's solve
3(x-5)=18
Open the bracket
3x-15=18
Add 15 to both sides
3x=3
Make x the subject of formula by dividing both sides by 3
x=1
So the final answer is 1
A. 4.18
B. 8.36
For the first one
