Y=-3x+8
when x=-2:
y=-3(-2)+8
y=6+8
y=14
when x=0
y=-3(0)+8
y=0+8
y=8
when x=2
y=-3(2)+8
y=-6+8
y=2
Answer:
23 out of 24, 92%
Step-by-step explanation:
firt see how many there are in one whole
multiply by three
minus 1 =23
round up and convert
the exponent tells you how many times to multiply the base number by itself.
for 35 the base number or base is 3 and the exponent is 5
the value is 3 x 3 x 3 x 3 x 3 which has 3 multiplied by itself five times
So your question is going in the opposite direction.
Rather than going from a power and expanding it, we have the expanded form and we are asked to write the power
3 x 3 x 3 is written 33

- Radius: r = d/2
- Surface Area of a Sphere: SA = 4πr²
Step-by-step explanation:
<u>Step 1: Define</u>
d = 19 cm
<u>Step 2: Find </u><em><u>SA</u></em>
- Substitute [R]: r = 19 cm/2
- Divide: r = 9.5 cm
- Substitute [SAS]: SA = 4π(9.5 cm)²
- Exponents: SA = 4π(90.25 cm²)
- Multiply: SA = 361π cm²
- Multiply: SA = 1134.11 cm²
- Round: SA ≈ 1134 cm²
Answer:
Choice B
Step-by-step explanation:
We can perform a least squares regression model in Ms. Excel to determine the equation of the line of best fit for the data given;
The first step is to enter the data into any two adjacent columns of an excel workbook. Next, click on the Data ribbon followed by the Data Analysis tool pack. We then proceed to select regression from the pop-up window. The final step is to select the y range and the x range of values from our data.
Once we click ok, Excel returns our least squares regression model as shown in the attachment below.
The coefficient of X variable 1 is our slope.
