Answer:
y = -2/3x + 23/3
Step-by-step explanation:
Let equation of the line be y = mx + c
m = (3-5)/(7-4) = -2/3 gradient/slope formula
sub (4, 5)
5 = -2/3 (4) + c
c = 23/3
therefore, equation of the line is y = -2/3x + 23/3
Hope it helps! :)
This is a topic called coordinate geometry. If you would like to find out more you can follow learntionary on instagram. I'll be posting some notes on coordinate geometry soon and I'll also post other useful math stuff as well :)
I want to say -1. if you first combine like terms the equation would look like 2-2x. then next step i did was divide both sides by negative 2 to get the x by itself. after i did that i got -1 x.
Answer:
x/3-10=8
x/3=18
x=48
Step-by-step explanation:
F(x)= x² + 8
When x = 10
f(x) = 10² + 8 = 108
Answer: 108
Answer:
Last option (bottom right)
Step-by-step explanation:
The scientific notation for 0.002 is 
(you move the decimal 3 to the right to get 2)
multiply the number of mustard seeds with this and you get 80. In scientific notation it is 
(move the decimal 1 to the left to get 8.0)
