Answer: y = 1/2 x 7
Step-by-step explanation:
Get the apparent line that generally passes through the mean values of the values represented in the scatter plot. Find the Slope.
The easiest way is to the difference between the highest and lowest y-values (or the average of two of the highest and lowest) So around about 17.5 - 8.5 = 9 Divide by the difference in x-values 18- 1 = 17 9/17 ≈ .53 Round to .5 ≈1/2
Of the choices given, only the last one has the correct slope. If you were to graph this line, passing through the apparent mean of the values (about half the points above and half below the line) it would intersect the y-axis at about y=7
Let's solve it!
So, let's study each factor.
x + 7 = 0 -> x = -7
x² - 49 = 0 -> x² = 49 - > x = ± √49 -> x = <span>± 7
Final answer: x = 7 and x = -7

Solve for Y when x = 1:
y = log5 (1)
Y = 0
Solve for X when Y = 1
1 = log5 x
X = 5
The graph that includes the two points (1,0) and (5,1) is B.
Answer:
The value of .
Step-by-step explanation:
Given:
We need to solve this equation.
Solution:
First combining equation having same denominators we get;
Now denominators are common so we will solve the numerators we get;
Now by cross multiplication we get;
Now Applying distributive property we get;
Now Combining the like terms we get;
Hence on solving we get the value of .
