Answer:

y = -9

Step-by-step explanation:

Expand:

2y − 8 + 5 = 3y + 6

Simplify 2y-8+5 to 2y-3:

2y − 3 = 3y + 6

Subtract 2y from both sides:

−3 = 3y + 6 − 2y

Simplify 3y + 6 - 2y to y + 6:

−3 = y + 6

Subtract 6 from both sides:

−3 − 6 = y

Simplify -3 - 6 to -9:

y = −9

2(y-4)+5=3(y+2)

multiply the first bracket by 2

(2)(y)=2y

(2)(-4)=-8

multiply the second bracket by 3

(3)(y)=3y

(3)(2)=6

2y-8+5=3y+6

2y-3=3y+6

move 3y to the other side

sign changes from +3y to -3y

2y-3y-3=3y-3y+6

-y-3=6

move -3 to the other side

-y-3+3=6+3

-y=9

multiply both sides by -1 to get +y

(-1)(-y)=9(-1)

Answer:

y=-9

A certain brand of coffee costs $2.99 for 11.3 ounces. What is the unit rate? Enter your answer, rounded to the nearest cent, in

Marysya12 [62]

To find the unit rate, you would do 2.99 / 11.3 and get about 26 cents. So the unit rate would be 26 over 1 ( 26/1 ).

Hope I helped!

Write the equation of the line that passes through (-1, 11) and (3, -5)

Genrish500 [490]

Answer:

y= -4x+7

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Let's find the gradient of the line first.

$gradient = \frac{y1 - y2}{x1 - x2}$

Using the above formula,

$m = \frac{11 - ( - 5)}{ - 1 - 3} \\ m = \frac{11 + 5}{ - 4} \\ m = \frac{16}{ - 4} \\ m = - 4$

Susbt. m= -4 into the equation:

y= -4x +c

Subst. a coordinate to find c.

When x=3, y= -5,

-5= -4(3) +c

-5= -12 +c

c= 12 -5

c=7

Thus the equation of the line is y= -4x +7.

Hey, everyone. This is from canvas, the picture I included was my grade. I believe this is called Box and Whiskers, I'm not sure

Ilya [14]

Answer:

Yes

Step-by-step explanation:

This is called Box and Whiskers or box plot.

The box in the middle contains 50% of data and the right end of the box is 75th percentile, you are correct.

25% of data is distributed to the left and 25% of data to the right of the box that is in the middle.
