Divide the 3 by the answer and you get the answer. the answer is 17
The slope will be the number that always sits next to x. So the slope in this case is 3/1. Which is rise over run. If it was a fraction, like 1/3, that would mean that the slope is rise one, run three.
If you want to find the y-intercept, you do that by putting a zero in for x, so you want to find the point that the line intersects the y-axis. So x would be zero, and wherever that point is is the y-intercept. In this case:
y = 3x - 1
y = 3(0) - 1
3 times 0 is zero
y = - 1 So, the y-intercept is - 1, or (0,-1)
To sketch the graph, you just place any number in for x or y (x is easier in this case), and solve it.
For example, I am going to say that x equals two.
y = 3(2)-1
y = 6-1
y = 5
So, your point to put on the graph would be (2,5) (x,y)
Answer:
He should leave by 10:30 a.m
Step-by-step explanation:
If he drives 60 miles per hr it will take him 270÷60=4.5 (4 n half) hrs to reach there.
If he want to be there at 3p.m he should leave by 10:30 a.m
Answer:
x = 63.43 , 243.43 degrees for 0 <x < 360.
Step-by-step explanation:
tan x = 2
The angle in the first quadrant whose tangent is 2 is x = 63.43 degrees.
If we consider the range 0 < x < 360 degrees tan x is positive in the third quadrant so x is also 180 + 63.43 = 243.43 degrees.
The equation cannot be solved, but it can be simplified.
You can't add variables with different exponents. For example, you can't add
with because they have different exponents
