Step-by-step explanation:
Hey there!!
During evaluating the expression, you must follow,
- put the value as given.
- work according to the mathematical operation sign.
Here,
![i). \: b + {c}^{2}](https://tex.z-dn.net/?f=i%29.%20%5C%3A%20b%20%2B%20%20%7Bc%7D%5E%7B2%7D%20)
![= 30 + {6}^{2}](https://tex.z-dn.net/?f=%20%3D%2030%20%2B%20%20%7B6%7D%5E%7B2%7D%20)
= 30+36
= 66.
ii). b-4c
= 30 - 4×6
= 30 - 24
= 6

Answer:
y=-2x+2
Step-by-step explanation:
The slope is -2x, meaning that the y-intercept can be found by working backwards from the given point. If the y value of the point is 4, subtracting 2 to get you to the point (0, 2) would provide the y-intercept.
Slope Intercept form is y=mx+b (m is the slope, x is the entered value, b is the y intercept)
Answer:
C. The functions have the same y-intercept
Step-by-step explanation:
In slope intercept form, y = mx + b, b represents the y-intercept, and in the first function the y-intercept is 10.
The y-intercept is when x = 0, and in the chart, when x equals 0, y equals 10.
10 = 10, so they have the same y-intercept.
Volume of the bottom rectangle:
12 x 4.5 x 5.5 = 297 cubic cm
Volume of triangle:
1/2 x 12 x 5 = 30 x 4.5 = 135 cubic cm
Total volume = 297 + 135 = 432 cubic cm
Answer:
x = 16
Step-by-step explanation:
12(x - 20) = -48
Use distributive property
12*x - 12*20 = -48
12x - 240 = -48
Add 240 to both sides
12x = -48 + 240
12x = 192
Divide both sides by 12
x = 192/12
x = 16
