Answer:
1
Step-by-step explanation:
By gradient, if you mean the "slope" of the linear function, then you have to find two points of the graph and use the "rise over run strategy". Given two coordinates, (x1, y1) and (x2, y2) of a linear function in the form y=mx+b, the slope of the line is (y2-y1)/(x2-x1). This shows the amount of "rise", or the vertical change, and the amount of "run", which is the horizontal change. Rise/Run gives the steepness of the line. The slope can also be modeled by Δy/Δx, which is the change in y over the change in x
Plugging in the given points (0,5) and (-5,0):
(y2-y1)/(x2-x1)= (5-0)/(0-(-5)) = 5/5 = 1
I basically moved the x from left to right and the moon I still had a 3 for y so I divided every number by 3 to get y by its self
Answer: y= -2/3x+2
Answer:
length = 13 feet and width = 5 feet
Step-by-step explanation:
let width be w then length is 2w + 3 ( 3 more than twice the width )
Equate the sum of length and width to 18, that is
w + 2w + 3 = 18, that is
3w + 3 = 18 ( subtract 3 from both sides )
3w = 15 ( divide both sides by 3 )
w = 5
That is the width is 5 feet and
length = 2w + 3 = (2 × 5) + 3 = 10 + 3 = 13 feet
Answer:
D. 0.43, because 13 of the 30 days were cloudy
Step-by-step explanation:
The fist thing that you should do is divide 100 by 30. We will do this so taht our percentages add up to 100. When we do this we get 3.333. Next we need to multiply this by the nubert of cloudy days 13 to get the answer D.
To get the ratio first add both sides of the ratio then divide it by the number of the cars then you get a 30 per 1 ratio so then if you times 30 to 3 that means it is 90 and then there are 150 blue cars using that math and to make sure that is right you can check it by adding the total red cars and blue cars you got. 150 + 90 = 240 which is the total. so your answer is 90 Red Cars
