A line with slope 3 passes through the point (0,10). What is the y-coordinate of the point on the line with x-coordinate 2?
lana [24]
Hello!

So to find the y-coordinate we need an equation for the line. The equation we can use is

y = mx + b

In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.

10 = 3(0) + b
10 = 0 + b
10 = b

So now that we've found b, we can use this in our equation

y = 4x + b

So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.

y = 4(2) + 10
y = 8 + 10
y = 18

18 is your y-coordinate

Which is bigger 0.17 or 0.165 meters
zavuch27 [327]
Your numbers are .17 and .165 meters

Let me explain each digit value:

Lets start with .17

Decimals are like whole numbers where each placement has a digit value

.1 is the tenths place

.07 is the hundredths place

Lets turn to .165

.1 is the tenths place

.06 is the hundredths place

.005 is the thousandths place

When seeing which decimal is larger, go along the tenths place and move along.


So as you can see
, .17 and .165 start with .1 so you can't see which is bigger by this. Now move on to the next digit. Which is larger? .17 or .16? As you should know, 7 is bigger than 6 so that means .17 is larger

Answer: .17 meters is larger than .165 meters

Answer:

11

Step-by-step explanation:

Evaluate using

First we do what is inside of the Parenthesis 12 - 9 = 3

Now we have 2 + 3²

Next is Exponents 3² = 9

Now we have 2 + 9

there is no multiplication or division needed so we go straight to addition

9 + 2 = 11

So we can conclude that the answer is 11

Is 3/8bigger than 4/10
mojhsa [17]
The way to work this out is to find a common denominator. so in this case 80 is a common denominator. So it would be 3/8 into 30/80 and then 4/10 into 32/80 therefore 4/10 is bigger
