Answer:

-2

Step-by-step explanation:

y=k/x

Replace y with 7 and x with -2

7=k/-2 gives you -14

Then you can replace k with -14 and x with 7

y=-14/7 gives you -2

Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form. A) y – 1 = 2(x – 3) B) y – 3
fomenos
So point slope form is y=mx+b where m=slope and b=y intercept so

in (x,y) form
one solution is x=1 and y=3, also slope is 2 so
m=2
subsitute
3=2(1)+b
3=2+b
subtract 2
1=b
equation is
y=2x+1

tricky answers so simplify them
A: y-1=2(x-3)
distribute
y-1=2x-6
add 1
y=2x-5
not the answer

B: y-3=2(x-1)
distribute
y-3=2x-2
add 3
y=2x+1
correct
the answer is B

Y=logxif y=10, then what is x
Kamila [148]
Assuming the logarithm is base 10, you have

y=10=\log_{10}x\implies 10^{10}=10^{\log_{10}x}\implies 10^{10}=x

Can anyone help not understanding? And can you explain how you got it. Thanks for all your help!
Allushta [10]
No, the height wouldn't be 70 feet, it would be 80 feet.

You would get this answer by using the equation h= A/b (h meaning height)
A = area ( or 20,000)
b= base ( or 250)

Then you divide A by b:
20,000/ 250 = 
80

I hoped this helped! :)
