Step-by-step explanation:
66. Δy = -3.4 Δx
Δy/Δx = -3.4
The slope of the line is -3.4. Slope-intercept equation of the line is:
y = -3.4x + b
Plug in the given point to find b:
2 = -3.4(4) + b
b = 15.6
Therefore, the equation is y = -3.4x + 15.6.
Use the equation to find the y coordinates.
68. Repeat the same steps as 66.
Δy = -1.7 Δx
Δy/Δx = -1.7
The slope of the line is -1.7. Slope-intercept equation of the line is:
y = -1.7x + b
Plug in the given point to find b:
3 = -1.7(-7) + b
b = -8.9
Therefore, the equation is y = -1.7x − 8.9.
Use the equation to find the x or y coordinates.
Answer:
t = 40
Step-by-step explanation:
Given the logarithmic expression:
Use the Logarithmic Property (Quotient Rule):
Next, using the Logarithmic Property:
We must determine the possible value of <em>t</em> that can be divided by 5 to produce a quotient of 8 that will make the <u>logarithmic property</u>, , true. In that case,<em> t </em>= 40 divided by 5 results in a quotient of 8.
Therefore, the value of <em>t</em> = 40.
