Answer:
40 cars
Step-by-step explanation:
The total percentage of Ariana's car collection should be = 100%
35% of the collection = 14
1 percent = 14/35
1 percent is therefore 0.4
To get the total number of cars in Ariana's collection, we multiply 100 by 0.4
= 100 x 0.4 = 40
Therefore the total number of cars in her collection is equal to 40 and this is the answer to the question.
Another way to solve this is by cross multiplication
35% = 14
100% = ?
When we cross multiply we have:
(100x14)/35
= 1400/35
= 40
Thank you!
Answer:
-13x^2+8x-3
Step-by-step explanation:
Question 2.
(1,0) would go (-1,0)
(3,0) would go (-3,0)
(5,3) would go (-5,3)
(1,3) would go (-1,3)
question 4. (i think)
(0,-1) would go (-1,0)
(0,-2) would go (-2,0)
(-2,-2) would go (-2,2)
(2,0) would go (0,2)
question 5.
(-1,4) would go to (1,4)
(-1,2) would go to (1,2)
(-3,2) would go to (3,2)
(-4,4) would go to (4,4)
hope this helps! good luck!
Slope-Intercept Form: y=mx+b
Standard Form: ax+by=c
Point- Slope: (y-y1)= m(x-x1)
There are multiple answers to your question-
- If you are only missing b(the y-intercept) but are given a set of points, plug the points into x and y and solve for b.
- If you are only missing the slope(m) but are given a set of points, plug the points into x and y and solve for m.
- If you are given the standard form/point-slope form, change the equation to slope intercept form.
- If you are given an complete form(there is an x and y; no missing variables), but are not sure what it is, plug in some numbers in x to find y, then graph.
