Step-by-step explanation:
you have to add and substract is easy
Answer:
(a) m= 3
(b) b= -2
(c) y=3x-2 or y=3x+(-2)
Step-by-step explanation:
(a) to find the slop you do rise over run or change in y over change in x (from point to point it goes up 3 over 1 so the slope would be 3/1 = 3)
(b) the y intercept is wherever the line intercepts (touches/crosses) the y (vertical/up and down)axis
(c) the equation formula is y=mx+b where m = the slope and b = y intercept. All you have to do is plug in the information to get your answer. You can also either add a negative or just subtract which is why there are two viable optional answers
Answer:
3:5
Step-by-step explanation:
Im going to assume for the last one you mean oranges to apples, which is 5:3
To get the ratio of apples to oranges you must understand how many there are of each, meaning there are 3 apples and 5 oranges.
Then you put it as a ratio
Apples:Oranges
3:5
You do the same for the second question, if my assumption is correct.
Oranges:Apples
5:3
To solve for XY we will set up a proportion. Lets do it:- Den solve:-
Now lets solve for x:-
Cross multiply;-
16.5 × 8.5 = 140.25
Divide:-
140.25 ÷ 17 = x
140.25 ÷ 17 = 8.25
x = 8.25
CHECK OUR WORK:-
16.5 × 8.5 = 140.25
17 × 8.25 = 140.25
We were RIGHT!!
So,
x = 8.25. (In your pic XY = 8.25)Hope I helped ya!!!
