Which is less, 2/5 or 4/5?

$\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

I'll use a cake for explanation.

Suppose we have a cake, and one of your companions, Mary, is hungry, so she takes 2/5 of one cake. Then, your other friend, Bella, takes 4/5 of the cake.

Then you compare the cakes. Who has less, Mary or Bella?

That's right, Mary.

So 2/5 is less than 4/5.

A line with a slope of 2 passes through the point (9, 10). What is its equation in slope-intercept

defon

Answer:

y=2x-8

Step-by-step explanation:

Hi there!

We want are given a line with a slope of 2, that passes through the point (9, 10)

We want to find the equation of this line in slope-intercept form

Slope-intercept form can be written as y=mx+b, where m is the slope and b is the y intercept

As we are already given the slope, we can immediately plug it in as m in the formula.

y=2x+b

Now we need to find b, which is the value of the y intercept

As the equation passes through the point (9, 10), it is a solution to the equation, meaning that if we plug it into the equation of the line, it will create a true statement.

So we can use its values of x and y to help us solve for b.
Substitute 9 as x and 10 as y in the equation.

10=2(9) + b

multiply

10=18+b

Subtract 18 from both sides to isolate b on one side

-8=b
Substitute -8 as b into the equation

y=2x-8
Hope this helps!

If you would like additional problems to practice, here are two of them, both with explanations (n.b., the solution to the first link included uses a different method from the one in this answer.)

Which of the following points is NOT a solution of the inequality y ≥ Ixl + 3?

omeli [17]

Hey there!

To solve this, we need to plug each of our answer options into the inequality and see if it is true. Which ever one doesn't make the inequality true when plugged in is the answer.

OPTION A

(x,y)=(-3,0)

We plug our values into the inequality.

0≥ I-3I+3

You may have noticed the bars surrounding the negative three.. If you didn't know, this is called absolute value. Absolute value is how far the number is from 0 on the number line. -7 is 7 away from 0 on a number line, so the absolute value of -7 is 7. The absolute value of 7 is 7. The absolute value of 0 is 0. Absolute value is signified by these bars. Le'ts finish evaluating.

0≥6

As you can see, zero is not greater than or equal to six. So, option A is false.

Since A is not a solution, we already know that that is the answer, so we don't even need to check B and C. But, we can still evaluate them if you want.

OPTION B

6≥I-3I+3

6≥6

This is true.

OPTION C

4≥I0I+3

4≥3

This is also true.

Therefore, the answer is A. (-3,0)

Have a wonderful day!

I need 3 coordinates for this linear equation <br> -5x-18=-4y

Elden [556K]

I'd start by finding the x and y intercepts. If x = 0, then y = 18/4 so your coordinate would be (0, 18/4). When y = 0, then x = 18/5 so your coordinate would be (18/5, 0). Now, if you solve it for y and pick a value for x, like 1 for example, you could find you y very easily. $y= \frac{5}{4} x+ \frac{18}{4}$ . Choosing x = 1, you would get y = 5/4 + 18/4 and y = 23/4. So your 3 coordinates could be (0, 18/4), (18/5, 0), and (1, 23/4)
