Answer:

y = 7x

Step-by-step explanation:

1: slope (m)- as the x-variable goes up by 1, the y-variable goes up by 7. So, the ∆y/∆x = 7. Therefore,<em> the slope is 7</em>.

2: y-intercept (b)- When x = 0, <em>y also has to be 0</em>, since all of the x-variables multiplied by 7 gives the related y-variable, without any adding.

3: plug in- y = 7x + 0 --> y = 7x

You have to write a linear equation that fits these points. For this, you will need to find the slope and the y intercept of the points.

To find the slope, get any two points provided. I will use (1,7) and (2,14). The formula to find the slope is y²-y/x²-x. This just means that you subtract the first y value from the second, so 14-7=7, and divide by the second x value minus the first, so 2-1=1. Now you divide 7/1=7, and that is your slope.

The y intercept is the y coordinate when x is zero. You can see that the pattern in the table is to add 7 each time, so when x is 0 y would be 0 as well. This means that your y intercept is 0.

Now to write the actual equation, m=slope and b=y intercept. Just plug in your values into the y=mx+b equation to get y=7x+0, or just y=7x. ;)

Which of the following is the inverse of y = 12 Superscript x? y = log Subscript one-twelfth Baseline x y = log Subscript 12 Bas
wariber [46]

Answer:

y = lnx/ln12

Step-by-step explanation:

Given the function y = 12^x, to find the inverse of the function, we news to write x as a function of y as shown:

Given y = 12^x

Taking ln of both sides

ln y = ln 12^x

ln y = xln12

Divide both sides by ln12

lny/ln12 = xln12/ln12

x = lny/ln12

x = ln(y-12)

Replacing y with x and x with y

The inverse of the function will be:

y = lnx/ln12

I really need help with my homework. <br><br> factorise 10x+25
alina1380 [7]
5(2x + 5), because 10x and 25 only have 5 in common, which is why it's outside the bracket, and 5 × 2x is 10x, and 5 × 5 is 25. Hope this helps!

Please help me!! Use the identities
jarptica [38.1K]

Answer:

tan 5π/24.

Step-by-step explanation:

We use the identity:

tan (A - B) =   (tan A - tan B) / (1 + tan A tan B)

so the first expression simplifies to

tan ( π/3 -  π/8)

= tan 5π/24.
