Step-by-step explanation:
the slope (or gradient) of a line is the factor of x.
in our case here : 3
it is expressed as ratio y/x and represents the amount of units y changes (and via the sign in what direction), when x changes a certain amount of units (again, via the sign in what direction). like when going from a point 1 to a point 2.
so, here we have 3 = 3/1, and that means, when x changes by 1 unit to the right (positive), y changes 3 units up (positive).
the y-axis intercept is simply the point, where x = 0. clearly, any point with the x coordinate being unequal to 0 cannot be on the y axis.
so, here
y = 3×0 + 7 = 7
=>
the y-axis intercept point is (0, 7).
Question 12: There are only red, black and green pens in a box.
There are three times as many red pens as green pens.
There are four as many black pens than red pens.
Work out the probability of a black pen being selected
working pls !! :D
Answer:
3/4
Step-by-step explanation:
Let the number of black pen be b, the green pen be g and the red pen be r.
Probability of a black pen being selected = 12g/16g = 3/4

Write a function rule in terms of x and y for the line that contains the points (-7.4, -9.7) and ( 8.4, 6.1) .
Answer:
y = x + -2.3
x = -y - 2.3 (but why would one need this?...)
Step-by-step explanation:
(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1
6.1 = 8.4 + b
b = -2.3

find three consecutive even integers whose sum 72
22, 24, 26
Step-by-step explanation:
2n - 2 + 2n + 2n + 2 = 72
6n = 72
n = 72/6
n = 12
∴ so three consecutive even integers whose sum is 72 :
2n - 2
= 2(12) - 2
= 24 - 2
= 22
2n
= 2(12)
= 24
2n + 2
= 2(12) + 2
= 24 + 2
= 26
verification
22 + 24 + 26
= 46 + 26
= 72 ✓✓

Mason is driving on a long road trip. He currently has 12 gallons of gas in his car. Each hour that he drives, his car uses up 1.5 gallons of gas. How much gas would be in the tank after driving for 2 hours? How much gas would be left after tt hours?
Answer: 9
12-1.5t
Step-by-step explanation:
1.5*2=3
12-3=9
1.5*t=1.5t
If he used 3 gallons of gas. Then the amount of the gas in the tank after driving for 2 hours will be 9 gallons.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
Mason is driving on a long road trip. He currently has 12 gallons of gas in his car. Each hour that he drives, his car uses up 1.5 gallons of gas.
Then the amount of the gas in the tank after driving for 2 hours will be
The amount of gas used in 2 hours will be
Used gas = 2 x 1.5
Used gas = 3 gallons of gas
Then the remaining amount will be
Remaining amount of gas = 12 - 3
Remaining amount of gas = 9 gallons
