Answer: 700
Step-by-step explanation:
35 x 20 = 700
<span>Slope of line passing through given points (-7.1, 11.4) and (-3.1, 3.4) can be calculated as below
(3.4 - 11.4)/ (-3.1 - (-7.1)) = -8/4 = -2
Given equation is in slope form of the line, i.e y = (-3/4)x + 3; By rearranging terms in the equation we can get its standard form as
4y = -3x + 12, which is same as 3x +4y = 12</span>
Answer:
f(5) does not equal 13.
Step-by-step explanation:
When we are given a function f(x), we can substitute any value for x as long as we change that value in the equation as well.
Therefore, if we are given f(5), we changed the x. Therefore, we also change the x in the rest of the equation. This would leave us with f(5) = 5² + 3. Now, we can just simplify.
f(5) = 5² + 3
f(5) = 25 + 3
f(5) = 28
Because we are asked to find if f(5) is equal to 13, we can see that 28 is definitely not equal to 13 and determine that this statement is false.
A postive linear associtation
(89 + 93 + 95 + 92 + 90 + x)/6 = 90%
(459 + x)/6 = 90% (multiply by 6)
459 + x = 540
x = 540 - 459
x = 81
check...
(459 + 81)/6 = 90%
540/6 = 90%
90% = 90% (correct)
She would need to have an 81
