Answer: C. Y = 5x + 5
Step-by-step explanation:
We need to write, or decide on, the equation for the blue line as this line represents the trend line for this scatter plot. We will write this in slope-intercept form. <em>See attached for a visual</em>.
First, we will find our slope. We will use
for this since we have a graph with clear points. See attached, we count up [5] and then count to the right [1] for a slope of 5.
-> Slope = 5
Now, we will find our y-intercept. This is where the line intersects the y-axis. The line hits the y-axis at point (0, 5) giving us a y-intercept of 5.
-> Y-intercept = 5
Lastly, we will write our equation and decide on an answer.
y = <em>m</em>x + <em>b</em>
y = (5)x + (5)
Y = 5x + 5
C. Y = 5x + 5

Answer:
<h2>10</h2>
Step-by-step explanation:
Given the expression
. To find the product of this two values, the following steps must be followed.
According to one of the law of indices, ![\sqrt{a} = a^{\frac{1}{2} }](https://tex.z-dn.net/?f=%5Csqrt%7Ba%7D%20%3D%20a%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D)
![\sqrt{10} * \sqrt{10}\\= 10^{\frac{1}{2} }* 10^{\frac{1}{2} }\\= 10^{\frac{1}{2}+\frac{1}{2}}\\ = 10^{1} \\= 10](https://tex.z-dn.net/?f=%5Csqrt%7B10%7D%20%2A%20%5Csqrt%7B10%7D%5C%5C%3D%2010%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%2A%2010%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%5C%5C%3D%2010%5E%7B%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B1%7D%7B2%7D%7D%5C%5C%20%3D%2010%5E%7B1%7D%20%5C%5C%3D%2010)
The product is 10
