Answer:

a) Yes.

b) Yes.

Step-by-step explanation:

Meredith and Hillary both want coffe, but they don't know if the other two people do, therefore they can't know if everyone want coffee. If they didn't want coffee, their answer would have been just "no".

Aly knows that she doesn't want coffee, therefore she knows that not everyone wants coffee.

The tables below show the values of Y for different values of X
pogonyaev

Answer:

Option D

Step-by-step explanation:

Rate of change of a linear function between two points (x_1,y_1) and (x_2,y_2) is given by,

Rate of change 'm' = \frac{y_2-y_1}{x_2-x_1}

From the given table,

Rate of change of the function between (-2, 6) and (-4, 9),

Rate of change 'm' = \frac{9-6}{-4-(-2)}

                           m = \frac{3}{-2}

Initial value = y-intercept

Let the equation of the line passing through a point (h, k) is,

y - k = m(x - h)

If a point (-2, 6) is lying on the graph of the function,

y - 6 = -\frac{3}{2}(x+2)

y = -\frac{3}{2}x-3+6

y = -\frac{3}{2}x+3

Y-intercept of the function = 3

Therefore, initial value of the function = 3

Option D is the answer.

Which two equations are equivalent to: 3(3x - 2) = 5(2x + 4) 9x - 6 = 10x + 20
zysi [14]

Answer:

C. -26=x

Step-by-step explanation:

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

9x-6=10x+20

9x-10x=20+6

-x=26

-x/-1=26/-1

x= -26

Can someone smart help me with this question plz:)
SOVA2 [1]

Answer:

K = 50

L = 90

KML = 40

LMN = 140

Step-by-step explanation:

The sum of the angles in a triangle will always be 180 degrees, and in the triangle pictured, we know the value of each angle. We can say that

5x + 4x + 9x = 180

18x = 180

x = 10

Now that we know the value of x, we can figure out the value of the angles.

K = 5x = 50

L = 9x = 90

KML = 4x = 40

A straight line is 180 degrees, so to find angle KMN, you have to subtract KML (4x) from 180

180 - 4x = 180 - 40 = 140
