Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = 
= 3 , then
y = 3x ← is the equation of the graphed line
Answer:
(4,5)
Step-by-step explanation:
The equation of a circle that has centre coordinates (a,b) and radius r is
(x-a)^2+(y-b)^2=r^2
so (4,5) satisfy the equation
3^2+4^2=9+16=25
The probability can be calculated as given because there are a total of 52 cards.
<h3>What is probability?</h3>
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total number of card = 52
Number of king of heart = 1
P(getting a king of hearts) = 1/52
P(getting a spade) = 13/52 = 1/4
P (getting a 5 or a club) = (16/52) = 4/13
P(getting a 5 or a 7) = 4/52 + 4/52 = 8/52 = 2/13
P(getting a card which is not a spade) = 1 - 1/4 = 3/4
P(getting 11 of clubs) = 1/52
Thus, the probability can be calculated as given because there are a total of 52 cards.

y=-7x+2
m=-7, so that's a negative slope.
b=2, so the y-intercept is (0,2). That's a postiive y-intercept.
Solve 0=-7x+2 to find the x-intercept.
7x=2
x=2/7
The x-intercept is (2/7,0), so that's a positive x-intercept.
Answer:
4 * 10^6
Step-by-step explanation:
3,796,742 is about 4,000,000
4 * 10^? = 4,000,000
4 to 4,000,000 is an extra 6 zeroes
? = 6
4 * 10^6
