The maximum value of a is 10, when b is 0
Answer:
3 1/2cm
Step-by-step explanation:
Answer:
18° and 72°
Step-by-step explanation:
let x be the measure of one angle then the other is 3x + 18
The sum of the 2 complementary angles = 90°, hence
x + 3x + 18 = 90
4x + 18 = 90 ( subtract 18 from both sides )
4x = 72 ( divide both sides by 4 )
x = 18
the 2 angles are 18° and (3 × 18 ) + 18 = 72°
Answer:
True: If you add 6 to a, this will be greater than b.
Step-by-step explanation:
If the ordered pair (a,b) satisfies the inequality y < x + 6, then the coordinates of this point satisfy the inequality. Substitute into the inequality x = a and y =b:

Check all options:
A. Subtract 6 from b:

So, if you subtract 6 from b it will be less than a but never equal to a, so this option is false.
B.

So, a is greater than b - 6, not b. This option is false.
C. If you add 6 to a, then

This option is true.
D. a+6 is greater than b, so it cannot be less than b. This option is false.
<span>It will take Yanni 20 minutes to catch up with Tracy. This can be determined with the fact that average velocity equals change in distance divided by change in time. Rearrange the equation so that we are solving for the final time, then set Tracy's equation equal to Yanni's equation and solve for the final time.</span>
