Prime factorization: 84 = 2 x 2 x 3 x 7 which can also be written 2² x 3 x 7.
Y intercept means the y-coordinate of the point where the graph crosses the y-axis.
Given equation is:
Let x be 0, as at the y-intercept point, the x-coordinate of that point is always 0.
y=
Slope-intercept form is y = mx + b
where m is the slope of the line and b is the y-intercept of the line {the number without a variable}
-2x+6y = 5
6y = 2x+5
y=
Hence, slope is
Answer:
x = 42.9 m
Step-by-step explanation:
Corresponding sides of similar triangles MAB and MNP are proportional. This means ...
x/MP = MA/MN
However, we don't have a number for MA yet, so we need to find it.
MA +AN = MN
MA = MN - AN subtract AN
MA = 67.2 m - 32 m = 35.2 m
Now, we can use this to find x.
x = MP · (MA/MN) = (81.9 m) · 35.2/67.2
x = 42.9 m
Answer: B, y-6=5(x-2)
Step-by-step explanation: Point-slope form is y-y1=m(x-x1). Given that in ordered pairs the x point comes first, we know the left part of the equation needs to be y-6. We also know the slope is 5, so the first part of the right side is 5(x-x1). We know that the x is 2, so we have y-6=5(x-2).
Use pythagorians theorem a^2 + b^2 = c^2. 4^+20^ = 20.40 feet. The ladder is 20.40 feet long.
