Answer:
y = -4x + 5
Step-by-step explanation:
This linear function can be represented through the slope-intercept form, or y=mx+b. You already know your m value, 4, which is your slope. From there you can plug in your coordinate into the y and x values to find your y-intercept, or b.
y = mx + b
-3 = -4(2) + b
b = 5
Then you put it all together to form the equation f(x) = -4x + 5
always put the 1st number you would like to turn to scientific notation
so the 1st number here is 3
then you turn 8 into a decimal because it is the only other number that isnt 0 and then it is 3.8
you then count every number after 3 including 8 which is
then you always put 10 x whatever number you are doing but right now it is 3.8
and the answer is
10 x 3.8^7
Answer:
36/40, 47/101, 192
Step-by-step explanation:
(a)The numerator (top number of the fraction) is adding up by odd numbers in order.
From 1/40 to 4/40 you add 3, from 4/40 to 9/40 you add 5, from 9/40 to 16/40 you add 7, and from 16/40 to 25/40 you add 9.
The next number to add would logically be 11. So from 25/40 you would go to 36/40.
36/40 is your next fraction.
(b)
3+4=7,4+7=11,7+11=18,11+18=29,18+29=47
(c) 1*2=2,2*2=4,2*4=8,4*8=32,8*32=256,32*256=8,192
Answer:
Step-by-step explanation:
Answer:
x=15
Step-by-step explanation:
This is a simultaneous equation
2x-3y=45 ------------------------------ equation i
x+y=10 -------------------------------equation ii
from equation ii
x+y=10
make x the subject of the matter
we have,
x=10-y
in equation i
substitute x for 10-y
2x-3y=45----------------------i
since x=10-y
we have,
2(10-y) - 3y=45
20-2y=3y=45
collect like terms
-2y-3y=45-20
-5y=25
divide both sides by -5
we have y=-5
substitute y for-5 in equation i
x+y=10
x+-5=10
collect like terms
x=10+5
x=15
therefore
x=15
