What expression can you substitute for y in
this equation?
-4y + x = -27
Enter the correct answer.

Answers

Answer:

1/4x+27/4

Step-by-step explanation:

Here's the equation: -4y+x=-27

We'll need to isolate y on one side

subtract x from both sides

-4y=-x-27

divide everything by -4

y=1/4x+27/4

So you can substitute 1/4x+27/4 for y.

Riko wants to find the distance between the points (−2, −3) and (2, −5). His work is shown. StartAbsoluteValue negative 3 EndAbsoluteValue + StartAbsoluteValue negative 5 EndAbsoluteValue = 3 + 5 = 8. The distance is 8 units. Riko correct? Explain why or why not.

Answers

Answer:

Riko is wrong because she uses the wrong formula.

Step-by-step explanation:

Given the coordinate points (-2, -3) and (2, -5)

We are to find the distance between the two points

Using the formula:

D = √(x2-x1)²+(y2-y1)²

From the coordinates x1 = -2, y1 = -3, x2 = 2 and y2 = -5

Substitute

D = √(2-(-2))²+(-5-(-3))²

D= √(4)²+(-2)²

D = √16 + 4

D = √20

D = √4*√5

D = 2√5

This shows that Riko is wrong because she uses the wrong formula.

Answer:

No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.

What’s the ANSEWR to this

Answers

Answer:

20.25

Step-by-step explanation:

i think its asking for the long side

the pythagorean theorem states that in a right triangle a^2+b^2=c^2

a is 19

b is 7

c is the long side

19^2= 361

6^2= 49

361+49=410

410 =c^2

square root of 410 = ~20.25

Answer:

[tex]hypotenuse = \sqrt{ {19}^{2} + {7}^{2}} \\ = \sqrt{361 + 49} = \sqrt{410} \\ = 20.25[/tex]

20.25 is the right answer.

Can someone please explain slope in a way that might make sense.

Answers

Okay let’s take the question “Find the slope of the points (4, 1) and (-2, 7)” as an example

The slope of an equation or graph is the rate of change.

In order to find slope, we use the formula m=rise/run or m=y2-y1/x2-x1

“m” is equal to the slope

“rise” or “y2-y1” is the difference (subtraction) of the two y coordinates

“run” or “x2-x1” is the difference (subtraction) of the two x coordinates

Remember, the points we are using for this example are (4, 1) and (-2, 7)

m = y2-y1/x2-x1
m = 7-1/-2-4

1 and 7 are your y coordinates so you plug them in an find the difference (subtraction)

4 and -2 are your x coordinates so you plug them in an find the difference (subtraction)

It doesn’t matter whether you do “m=7-1/-2-4” or “m=1-7/4-(-2)” both will have the same answer

The only thing you can’t do is something like “m=7-1/4-(-2)” or “m=1-7/-2-4”

The bottom can’t be solved in the opposite way of how it was solved on top and vice versa of that makes sense

Also, keep in mind that if you see two negatives as in the “m=1-7/4-(-2)” example, you turn it into an addition symbol

Like this:
“m=1-7/4+2)”

Because two negatives are equal to a positive

m = y2-y1/x2-x1
m = 7-1/-2-4
m = 6/-6
m = 6/-6
m = -1

Remember that a negative divided by a positive is always a negative so it doesn’t matter where you place the negative sign

For example, if your slope was 2/-5, that would be the same as -2/5

And when you divide two negatives, it always equals to a positive

For example -2/-5 would simplify to 2/5

I hope that helped and made sense :)
