Evaluate the expression: 3/5+2^2−2/5(8−6)÷3

Hello there!

The GCF of 80 and 20 is 20.

Because both numbers are evenly divisible by 20; this is their greatest common factor (GCF)

Hope this helps you!

Step-by-step explanation:

6r + 7 = 13 + 7r

6r - 7r = 13 - 7

-1r = 6

r = 6/-1

r = -6

Step-by-step explanation:

y = 2x + 1

4y - 5x = 13

4(2x + 1) - 5x = 13

8x + 4 - 5x = 13

8x - 5x = 13 - 4

3x = 9

x = 9/3

x = 3

y = 2x + 1

y = 2.3 + 1

y = 6 + 1

y = 7

(x,y) = (3,7)

Answer:

A. y + 2 = 4/3(x – 3); –4x + 3y = –18

Step-by-step explanation:

(3, –2) and (6, 2)

First, we must establish slope...

m=(y-y1)/(x-x1)

m=(-2-2)/(3-6)

m=-4/-3

m=4/3

Point slope formula is...

y-y1=m(x-x1)

Let's select either coordinate.  I randomly select the first (3, –2)...

y--2=4/3(x-3)

Subtracting a negative number is the same as adding a positive number...

y+2=4/3(x-3)

This corresponds to the first answer.

Standard form...

Ax+By=C

y+2=(4/3)x-4

y=(4/3)x-6

-(4/3)x+y=-6

Multiply both sides by 3...

-4x+3y=-18

This also corresponds to the first answer.

How about the second coordinate, (6, 2)...

y-y1=m(x-x1)

y-2=(4/3)(x-6)

Let's convert it into standard form..

y-2=(4/3)x-8

y=(4/3)x-6

-(4/3)x+y=-6

Multiply both sides by 3...

-4x+3y=-18

FIRST ANSWER

y + 2 = 4/3(x – 3); –4x + 3y = –18

Answer:

Answer:

The first one.

Step-by-step explanation:

Find the asymptotes.

Vertical Asymptotes: x = − 2

Horizontal Asymptotes: y = 3

No Oblique Asymptotes

So it has to be y=(1)/(x+2)+3

Step-by-step explanation:

Sorry if it is wrong

Answer:

50% increase

Step-by-step explanation:

1st Question:

Our problem is [tex]-2x^2 - 10x + 100[/tex]

We have a common factor between the three terms, -2. So:

[tex]-2x^2 - 10x + 100[/tex]

[tex]-2(x^2 + 5x -50)[/tex]

We can factor further. What two numbers add up to 5 and multiply to -50? Our answer would be positive 10 and -5. Therefore:

[tex]-2(x^2 + 5x -50)[/tex]

[tex]-2(x +10)(x-5)[/tex]

2nd Question:

The problem is [tex]3x^3 + 9x^2 - 54x[/tex]

Like the first question, we can factor out a constant. In this case, we factor out a 3.

[tex]3x^3 + 9x^2 - 54x[/tex]

[tex]3(x^3 + 3x^2 - 18x)[/tex]

We can also factor out an x.

[tex]3(x^3 + 3x^2 - 18x)[/tex]

[tex]3x(x^2 + 3x - 18)[/tex]

We need to simply further. We can factor the quadratic into (x+6)(x-3).

[tex]3x(x^2 + 3x - 18)[/tex]

[tex]3x(x+6)(x-3)[/tex]

3rd Question:

Our problem is [tex]x^2 +12x + 20[/tex]

We do not have a coefficient, so we should factor the expression straight away. What two numbers add up to 12 and multiply to 20? the numbers 2 and 10. So:

[tex]x^2 +12x + 20[/tex]

[tex](x+2)(x+10)[/tex]

Answer:

y= -x+2

Step-by-step explanation:

If what they are asking for is slope-intercept format, then you need to isolate the y on one side.

So add -2x to both sides to get, -2y= 2x-4

After that you would divide both sides by -2, and when you do this you are dividing every single term by -2 so you would get,

y= -x+2

that is your slope- intercept formula.

so your slope is m= -1

Answer:

X-intercept: (2,0)

Y-intercept: (0,2)

Step-by-step explanation:

all it's asking for when it says "find the intercepts" is for two points, the one with 0 in the x position, and the one with 0 in the y position of the point (x,y).

These are surprisingly easy! Just plug 0 into x and solve for y. In this case, that gives us (-2)x(0)-2y = -4

Do some algebra and you'll find that y = 2. Since we plugged in 0 for x, that gave us the y-intercept: (0,2). (Remember, the y-intercept is when it intersects the y-axis. All points on the y axis have an X coordinate of 0!)

Now do the same thing but plug 0 in for y.

-2x - (2)x(0) = -4

-2x = -4

x=2

This gives us the x-intercept of (2,0)

Answer:

JJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJ

Step-by-step explanation:

The square root of 36 and 361 are 6 and 19 respectively.

A number when taken square root gives an integer is a perfect square number.

Given, we have to find the square root of 26 and 361.

Now by prime factorization,

36 = 2×18 = 2×3×6 = 2×3×2×3 = 2×2×3×3 = 2²×3².

Now the square root of 2²×3² = √2²×√3² = 2×3 = 6.

The square root of 361 can be found by knowing the square root of 400 which is 20.

Now we'll check if 19² = 361 indeed 19×19 = 361 so, the square root of 361 is 19.

Answer:

The slope is -8/5

Step-by-step explanation:

Slope is the change of y over the change of x.

Two x and y values for example are -7, -2, 9, and 1.

You would set up the expression where you put 9-1 in the numerator and -7-(-2) in the denominator. The answer would be 8/-5.

Thus, the slope is -8/5.
