How to solve 7-10: if a coordinate (x, y) is on the line, then f(x) = y.

7. Since x is 6, look at the graph, which shows that y (or f(x)) is 4. (look at picture)

8. Same thing as 7. you will see that f(x) is 15.

9. The other way around. since we know y = 2, looking at the graph shows us that x = 3.

10. Repeat process of 9. x = 10.

How to solve 11 + 12: slope formula (rise-over-run)

11. (14-4)/(12-6) = 10/6 = 5/3.

12. (16-14)/(18-12) = 2/6 = 1/3.

(If possible brainliest is appreciated :D)

A watch lost 1 minute 18 seconds in 39 days. How many seconds did it lose per day?
vlabodo [156]
ATO,
We should convert 1.18 minutes into seconds
1 minute = 60 seconds
60 + 18 seconds = 78 seconds
We should divide with the days
So,
78 seconds ÷ 39 days = 2 seconds per day.

So,it lose 2 seconds per day.

8 times the difference between a number and 6 is equal to 4 times the number.
7nadin3 [17]

Answer:

The variable titled "the number" is A: 12.

Step-by-step explanation:

The problem is 8 * (x - 6) = 4 * x

Try the first number as x and rewrite the expression.

8 * (12 - 6) = 4 * 12

Following PEMDAS (the Order of Operations), you need to solve the problem inside the parenthesis.

12 - 6 = 6

Rewrite the problem.

8 * 6 = 4 * 12

8 times 6 is 48.

4 times 12 is 48.

The variable in the expression 8 * (x - 6) = 4 * x is 12.

Find the area of the triangle. Round your answer to the nearest thousandths. <br><br> A=1/2 bh
Over [174]

Answer:

Step-by-step explanation:

height of triangle=√(11²-8.6²)=√(11+8.6)(11-8.6)=√(19.6×2.4)

=√(4×4.9×4×0.6)=4√(4.9×0.6)=4√2.94

area of triangle=1/2 bh=1/2×2×8.6×4√2.94

=34.4×√2.94

≈58.984
