Because both equations are to find Y, set them equal to each other to solve:

3x+6 = x+2

Subtract x from both sides:

2x + 6 = 2

Subtract 6 from both sides:

2x = -4

Divide both sides by 2:

x = -4 /2

x = -2

Now you have a value for x, replace X with -2 in one of the equations and solve for y:

y = 3x +6 = 3(-2) +6 = -6 +6 = 0

X = -2 and Y = 0

(-2,0)

What will be the cost for 8 hours of work? 10 hours of work?

andreyandreev [35.5K]

Answer:

Cost = 25 + 50h

cost for 8 hours of work = $425

cost for 10 hours of work = $525

Step-by-step explanation:

The question is as following:

A plumber charges $25 for a service call plus $50 per hour of service write an equation to represent the cost of hiring this plumber.

what will be the cost for 8 hours of work? 10 hours of work?

=======================================================

A plumber charges $25 for a service call plus $50 per hour

Cost = 25 + 50h

Where h is the number of hours of service

8 hours of work: h = 8

Substitute with h = 8 at the equation of cost

Cost = 25 + 50* 8 = $425

10 hours of work: h = 10

Substitute with h = 10 at the equation of cost

Cost = 25 + 50 * 10 = $525

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Boat A(3.1, -1)

Boat B(-4.1, -1)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(-4.1-3.1)^2+(-1+1)^2}$
Subtract/Add: $d = \sqrt{(-7.2)^2+(0)^2}$
Exponents: $d = \sqrt{51.84}$
Evaluate: $d = 7.2$

In a random sample of 205 people, 149 said that they watched educational television. Find the 95% confidence interval of the tru

tensa zangetsu [6.8K]

Answer: Given a sample of 200, we are 90% confident that the true proportion of people who watched educational TV is between 72.1% and 81.9%.

Step-by-step explanation:

$\frac{154}{200} =0.77$

$1-0.77=0.23$

$\sqrt{\frac{(0.77)(0.23)}{200} }$ =0.049

0.77±0.049< 0.819, 0.721
