Answer:
Below in bold.
Step-by-step explanation:
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
y - (-1)) = -2/5(x - -10)
y + 1 = -2/5(x + 10)
y + 1 = -2/5x - 4
y = -2/5x - 5.
In standard form this is:
2x + 5y = -25.
I'll do the first graph.
We can easily find the y intercept by inputting 0 for x.
y = -2(0) + 7
y = 7
The y-intercept is (0, 7)
To find the x intercept, isolate x.
y = -2x + 7
Add 2x to both sides.
2x + y = 7
Subtract y from both sides.
2x = -y + 7
Divide by 2 on both sides.
x = -1/2y + 3.5
Input 0 for y.
x = -1/2(0) + 3.5
x = 3.5
The x intercept is (3.5, 0)
Now try the rest own your own! :)
Answer:
Step-by-step explanation:
Hello!
The variable of interest is the weight in ounces of a soap bar.
Attached is a QQplot diagram.
A Q-Q plot is a diagram that compares two probability distributions, in this case, the probability distribution of the data set against the theoretical normal distribution. If the observed data matches the theoretical sets, you can say that that population follows said distribution.
As you can see in the graphic the observed values (blue dots) fit the normal theoretical quantiles, so we can say that the data appear to come from a normal distribution.
I hope it helps.
<h3><u>Given</u>:</h3>
- A rectangle has a height of 4 and a width of x² + 3x + 2.
<h3><u>To find</u>:</h3>
- The area of the entire rectangle.
<h3><u>Solution</u>:</h3>
Hence, we know that area of rectangle is equals to the product of length and breadth.
Therefore, the area of rectangle is,

Therefore, the answer is 4x² + 12x + 8.
