Answer:

In the form of

Y= mx+c

Y= 1/2x +2

m = 1/2

Step-by-step explanation:

A linear equation in it's standard form is in the format

Y= mx+c

Where m is the slope and c is the y intercept

Let's use these two points to determine both the slope and the equation

(2, 3), (4,4)

Slope= (y2-y1)/(x2-x1)

Slope= (4-3)/(4-2)

Slope= 1/2

Equation of the linear function

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

(Y-3)/(x-2)= 1/2

2(y-3) = x-2

2y -6 = x-2

2y= x-2+6

2y= x+4

Y= 1/2x +2

A phone company offers two monthly plans. Plan A costs S8 plus an additional $0.15 for each minute of calls. Plan B costs $17 pl
SashulF [63]

Answer:

Minutes = 225

Cost = $41.75

Step-by-step explanation:

It is given that:

Cost of Plan A = $8

Per minute cost = $0.15

Let,

m be the number of minutes

A(m) = 0.15m + 8

Cost of Plan B = $17

Per minute cost = $0.11

B(m) = 0.11m + 17

For same cost,

A(m) = B(m)

0.15m+8 = 0.11m + 17

0.15m - 0.11m = 17 - 8

0.04m = 9

Dividing both sides by 0.04

\frac{0.04m}{0.04}=\frac{9}{0.04}\\m = 225

Cost of 225 minutes

A(225) = 0.15(225) + 8

A(225) = $41.75

Therefore,

Minutes = 225

Cost = $41.75

(SAT prep) Find the value of x in each case of the following exercises:
yKpoI14uk [10]

The value of x from the figure is 70°

<h3>How to determine the value</h3>

It is important to note that alternate angles are equal and angles in a triangle sum up to 180°

We then have that,

x + 50 + 60 = 180 °

x + 110 = 180°

Make 'x' subject

x = 180 - 110

x = 70 °

Thus, the value of x from the figure is 70°

Solve for x: 3(x + 1) = -2(x - 1) - 4
shepuryov [24]

Answer:

x = -1

Step-by-step explanation:

3(x+1) = -2(x-1) - 4

3x + 3 = -2x + 2 - 4

3x + 3 = -2x - 2

Add the -2x to both sides

5x + 3 = -2

Subtract the 3 to both sides

5x = -5

Divide both sides by 5

x = -1
