Answer: 0 ≤ x ≤ 4.75
Step-by-step explanation: Domain is the range of possible x values that make sense in the equation. Since the x values are time, and there cannot be negative time, x must obviously be positive. And since y is height and height can't be negative, the domain of x ends at the x-intercept, the point at which y begins to become negative. So the domain of x is 0 is less than or equal to x which is less than or equal to about 4.75.
Answer:
The slope of (1,5) and (-3,0) is 5/4
the slope of (-2,4) and (3,0) is -4/5
Step-by-step explanation:
Answer:
5.3 hours
Step-by-step explanation:
Given:
3 hours = 8lbs. turkey
?? hours = 14lbs. turkey
Do proportions:
=
<-- Cross Multiply
42 = 8x <-- Solve for x
x = 5.25
Round to the nearest tenth:
x = 5.3 hours
Answer:
30:1
Step-by-step explanation:
1. Look at the graph and follow along the lines.
2. When x is 1 in hours then cakes are 30.
3. So we can write the ratio from cakes to hours.
4. The ratio is 30:1.
If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)
x + 21 = 2x - 40 Add 40 to both sides
x + 61 = 2x Subtract x from both sides
61 = x Switch the sides to make it easier to read
x = 61
