Let's start off with a simple y-intercept form.

y=mx + b
b represents the y intercept so we can substitute it with 2.
y = mx + 2
the point we are given, (1,1) is really just an x and y value. We can also substitute this into the equation.
y = x + 2

Now that we have some type of equation, we can convert it to the form shown in the answer choices by subtracting y from both sides.
0 = x - y + 2
Hope this helps!

Why does cube root 7 equal 7 to the 1/3 power

UNO [17]

Answer:

Step-by-step explanation:

Here's how you convert:

$\sqrt[n]{x^m}=x^{\frac{m}{n}$ The little number outside the radical, called the index, serves as the denominator in the rational power, and the power on the x inside the radical serves as the numerator in the rational power on the x.

A couple of examples:

$\sqrt[3]{x^4}=x^{\frac{4}{3}$

$\sqrt[5]{x^7}=x^{\frac{7}{5}$

It's that simple. For your problem in particular:

$\sqrt[3]{7}$ is the exact same thing as $\sqrt[3]{7^1}=7^{\frac{1}{3}$

Draw a line from each figure to an area

Georgia [21]

Answer:

A=27 cm^2

B=24 cm^2

C=26 cm^2

D=28 cm^2

Step-by-step explanation:

Break each problem down into individual shapes.

For instance, A can be split into a 3 by 3 square and a 6 by 3 square.

Get the area by multiplying the length & height: A = L * H

For the triangles the area is the same equation divided by 2 A=LH/2

Shapes with unclear dimensions like C can be skipped and have their area revealed through process of elimination.

Y-intercept is 100 and slope is 5. Partner gave example: Younger brother had 100 small building blocks, but lost 5 of them every

ArbitrLikvidat [17]

Since he lost 5 every month, it should be that the slope is -5, not 5, he is not gaining 5 every month

yint is 100 and slope is -5 would be correct
b=-5m+100
b=number of blocks he has after m months

How many natural numbers are less than n

ruslelena [56]

The number of natural numbers less than n is n-1.

Natural numbers are whole and positive numbers that are not 0.

If n is 2, there is one natural number less than n... and that is 1.

If n is 5, there are four natural numbers less than n... which are 1, 2, 3, and 4.
