Answer:

Answer:  y = x + 1 

Step-by-step explanation:

${ \tt{y = - 3x + 5}}$

» At point of intersection:

${ \tt{2 = - 3x + 5}} \\ { \tt{ - 3x = - 3}} \\ { \tt{x = 1}}$

» Point of intersection is (1, 2)

• General equation of a line:

${ \tt{y = mx + c}}$

m is slope
c is y-intercept

» Consider point (1, 2);

${ \tt{2 = (1 \times 1) + c}} \\ { \tt{c = 2 - 1}} \\ { \tt{c = 1}}$

Equation:

${ \tt{y = x + 1}}$

0.1 is 10% of what number?

stiv31 [10]

Let's assign a variable that is the number when multiplied by 10% it is equal to 0.1.

Well let that be x.

Now we want to convert the 10% into a decimal. To convert a percent into a decimal, simply move the % sign two places to the left and make it into a decimal point.

When we say "of" in mathematics what we really mean is to multiply.

0.10 * x = 0.1

That is the equation we need to find the value of x for.

Divide both sides by 0.10

0.10 * x = 0.1

The 0.10 on the left side cancels out.

x = 1

So, the answer to this question is if we multiply 10% by 1 we will get 0.1.
