Answer:
Y=mx+b
Step-by-step explanation:
mx = slope
b = intercept (the place where the line hits the y axis)
Answer:
see graph of y = 5x - 7
Step-by-step explanation:
If graphing is the task, you should rewrite the equation in a y = ax + b form. All straight lines can be described in this form, only the a and b determine which line it is.
Your equation 5x-y=7 has the 5x on the left side, so lets move it to the right. It will get a negative sign (this is the same as subtracting 5x like you did in your picture)
5x - y = 7
-y = 7 - 5x
Now we still have the -y which should be a +y. So we multiply left and right with -1 and get:
y = -7 + 5x
If we swap the -y and 5x (we can, because they are just an addition), we get:
y = 5x - 7
Now the equation is in its "normal" form. It's like the y = ax + b with a and b chosen as a=5 and b=-7.
The normal form is handy because you can immediately see the slope is 5 and the intersection with the y-axis is at y=-7.
The answer would be C! Correct me if I’m wrong guys
You should use the ratio so
2/ 4 = 6.5 / n
n= 6.5 x 4 / 2 = 13 inches
2- for two hours ------> four inches of snow
for x hours -----> y inches of snow
the equation is
2/4 = x/ y
x= 2y / 4
for x is the hours and y is the inches
exercice 2
5 gr granula ----------------------> 1750 calories
2 gr granula ----------------------> n ?? calories
by cross multiplication
n = 2 x1750 / 5 = 700 calories .
2-
she wants to eat 175 calories so
u put granula under granula and calories under calories to make this cross
<span>5 gr granula ----------------------> 1750 calories
</span>??? m granula ---------------------> 175 calories
<span>by cross multiplication </span>
m = 175 x 5 / 1750 = 0.5 gr of granula
Answer:
362881
Step-by-step explanation:
The right sequence should be
2,3,7,25,121,721,5041,40321, 362881
Here, the formula used is a(n)=n!+1 where n=1 to infininity
n(1) =2=1!+1=2
n(2)= 3=2!+1=3
n(3)=7=3!+1=7
n(4)=25=4!+1=25
n(5)=121=5!+1=121
n(6)=721=6!+1=721
n(7)=5041=7!+1=5041
n(8)=40321=8!+1=40321
n(9)=362881=9!+1=362881
