Use the equation y=mx+b where m is the slope (how much it increases each time) and b is the y intercept (starting point).
Your equation would be: y=12x+0 because they eat 12 pounds each day and they start out having eaten 0 pounds.
To solve the equation, plug in the total amount of food for y and use algebra to solve for x:
250=12x
(divide by 12)
(250/12)=x
X=20.833
Their food would last approximately 20 days. (Make sure you round if required)
No, these are not equal, here's why:
3 * 5 = 15
7 * 5 = 35
7 * 5 ≠ 45
Another good way to look at it is in fraction form:
3/7 is simplified
15/54 = 1/3
1/3 ≠ 3/7
So, in conclusion, these are not complementary ratios
Hope this helps.
Its the last option they both are as far from 0 on the number line
Hope this helps and good luck on ur guyss exams :)
Answer:
Step-by-step explanation:
When the question comes with answer choices, please share them. In this case it sounds like there were four graphs from which to choose.
f(x) = |x^2 − x − 2| is always zero or greater, due to the absolute value function.
x^2 − x − 2 = 0 factors to (x - 2)(x + 1) = 0, so the zeros of f(x) are {-1, 2}.
Plot x-intercepts {-1, 2}. The axis of symmetry is the vertical line x = 1/2, which is precisely halfway between the x-intercepts. If we now choose the test number x = 0, we find the value of f(0) to be |-2}, which tells us that the y-intercept is (0, |-2|), or (0, 2), so we have a parabolic curve opening down between x = -1 and x = 2 and touching (but not crossing) the x-axis at those x-values. To the left of x = -1 the curve increases steadily from y = 0 in Quadrant II; to the right of x = 2, the curve increases steadily from y = 0 in Quadrant I.
