Answer:
Step-by-step explanation:
We have the equation 
.
The ordered pairs of this equation have the form 
Where x is the independent variable and y is the dependent variabe.
That is, the points belonging to the line have the form 
For 
.
So, we need to find 
for x_0 = -3.
Then we substitute x = -3 into the equation and clear the value of y.
.
Then the ordered pair is:
Answer:
1) $63.60
2) y=8x-6
Step-by-step explanation:
1) $233.20 divided 11 hours is a hourly rate of $21.20. $21.20 multiplied by 3 hours is $63.60.
2) To find the slope you need 
. (10-2)/(2-1) is 8. The slope is 8. So you have y=8x+b. To find b just plug in a point and solve. 2=8(1)+b. B= -6. y=8x-6
Answer:
(4,-3)
Step-by-step explanation:
Easiest way to do this without any advanced methods is to use the answer choices to your advantage.
For a.) we have (1,1) meaning x = 1 and y = 1 if we get a 7 for the first equation and a -2 for the second equation then that is the correct answer.
Let x=1, y =1:
4(1)+3(1)=4+3=7 Correct so far.
1+2(1)=1+2=3 Incorrect since we should have got a -2 if this was the solution
Let (0,-1) x = 0, y = -1:
4(0) + 3(-1) = 0 -3 = - 3 Incorrect so we can stop there next answer choice.
Let (4,-3) x = 4 y = -3:
4(4)+3(-3)=16-9=7 Correct so far.
4+2(-3)=4-6=-2 Both are correct!
Therefore the solution (where the lines intersect) is (4,-3).
Step One: Line Up All the Digits. First, line up all of the numbers according to their place value.
Step Two: Multiply by the Ones Digit. ...
Step Three: Add a Zero Place Holder. ...
Step Four: Multiply by the Tens Digit. ...
Step Five: Add the Two Answer Rows Together.
Option C:
The value of x is 27.
Solution:
Given exterior angles are 56°, 2x°, 85°, 57° and 4x°.
<em>Sum of exterior angles of a polygon = 360°</em>
⇒ 56° + 2x° + 85° + 57° + 4x° = 360°
⇒ 198° + 6x° = 360°
Subtract 198° from both sides of the equation.
⇒ 6x° = 162°
Divide by 6 on both sides, we get
⇒ x° = 27°
⇒ x = 27
The value of x is 27.
Option C is the correct answer.
