Write the equation of the line that is parallel to y = -2x + 4 and passes through (3, 1) in slope-intercept form.
Answers
Answer:
y = -2x + 7
Step-by-step explanation:
y = -2x + 4
Slope in above equation is -2. Parallel lines share the same slope so the new equation will also have a slope of -2.
y-intercept through point (3, 1):
y = mx + b
1 = -2(3) + b
1 = -6 + b
b = 7
Equation of line that is parallel to original:
y = mx + b
y = -2x + 7

A photographer charges a sitting fee of $15 plus $3 for each pose. Write a function to describe the situation. Find a reasonable domain and range for up to 5 poses.
Please help i really don't understand how to find the domain and range.
Answers
Answer:y=3x+15
Step-by-step explanation: (1,18), (2,21), (3,24), (4,27), (5,30) domain is your x values 1,2,3,4,5. Range is your y values. I’d assume someone wouldn’t pay $15 for 0 poses.
The function for the given situation is f(x)=15+3x and a reasonable domain and range for up to 5 poses is 5 and 30 respectively.
Given that, a photographer charges a sitting fee of $15 plus $3 for each pose.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Let the number of poses be x and the total cost be y.
The function for the given situation is y=15+3x
Thus, f(x)=15+3x
For 5 poses:
Put x=5 in the obtained function, we get
f(5)=15+3(5)
= 15+15
= 30
So, the ordered pair is (5, 30)
Hence, the function for the given situation is f(x)=15+3x and a reasonable domain and range for up to 5 poses is 5 and 30 respectively.

Team score in first game < 19
Step-by-step explanation:
Point Scored in Third Game =X
Points Scored in First Game = X+6 (6 more than third game)
Points Scored in Second Game = 23
Total Points ={( First Game) +( Second Game) + (Third Game)} < 55
{ ( X+6) + (23) + (X)} < 55
X+29+X < 55
2X+29 < 55
2X< 55-29
2X < 26
X <26/2
X<13
So the point scored in First game is: (X+6)
Where X < 13
So the point in First game is < 19

The parallelogram shown bellow has an area of 15 units over 2
Answers
Answer:
The value of h is [tex]\frac{5}{2}[/tex] units
Step-by-step explanation:
In any parallelogram, there are two different pair of bases b1, b2 and their corresponding heights h1, h2, where h1 ⊥ b1 and h2 ⊥ b2The area of parallelogram = b1 × h1 OR b2 × h2In the given figure
∵ Every two opposite sides of the parallelogram are equal
∴ The length of the base of the height h is 3 units
∵ The area of the parallelogram = [tex]\frac{15}{2}[/tex] units
∵ Area of parallelogram = b × h
→ Substitute the values of the area and the base in the rule above
∴ [tex]\frac{15}{2}[/tex] = 3 × h
∴ [tex]\frac{15}{2}[/tex] = 3h
→ Divide both sides by 3 to find h
∵ [tex]\frac{15}{2}[/tex] ÷ 3 = 3h ÷ 3
∴ [tex]\frac{15}{6}[/tex] = h
→ Simplify the fraction by divide up and down by 3 and switch the 2 sides
∴ h = [tex]\frac{5}{2}[/tex] units

Triangle ABC in the figure above represents the area serviced by a shipping company that plans to build a distribution center at the incenter of the triangle located at point E. A circle is constructed to represent the location of the center. The diameter of the circle is 28 miles. The existing road is perpendicular to the incenter and the company is looking to build 2 more perpendicular roads but connecting the other 2 sides of the triangle. How many more miles of road will be needed?
Select one:
A. 28
B. 34
C. 43
D. 56
Answers
Answer:
A. 28
Step-by-step explanation:
A. 28
step 1.
We know that the diameter of the circle inscribed within the triangle is 28 miles, and we know that E is the incenter of triangle ABC.
step 2.
Next, we learned that the perpendicular legs from the incenter to the sides of the triangle are congruent, and we know that the radius of a circle is 1/2 of the diameter of the circle.
step 3.
Since the diameter of the circle is 28, we know the distance of segment DE is 14. Next, we know the perpendicular legs are equal to segment DE. Thus, we can solve for the amount of additional miles of road by writing 14 + 14 = 28.
The area of a rectangle is 72 square metres. The length of the rectangle is twice the width. Find the width of the rectangle.

Working:
Find common factors of 72:
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Work out which ones multiply together to make 72 and as the question states that the length is twice the width, we need to find two numbers that multiply to make 72 and one of the numbers is double the other number.
These numbers would be 6 and 12. (6 x 12 = 72)
Therefore:
Area = 72m²
Width = 6m
Length = 12m

x intercept of line b is (1,0)
The x intercept of line A is (-6, 0) and x intercept of line B is (3, 0)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Equation of line A
y=-2/3x-4
When y=0
0=-2/3x-4
4=-2/3x
-6=x
So the x intercept for line A is -6.
Let us find equation of line B by using table
Slope = -1
Now let us find y intercept
2=-1(-1)+b
b=3
So equation is y=-x+3
Now let us find the x intercept
Put y=0
0=-x+3
x=3
(3, 0) is x intercept of line B
Hence, the x intercept of line A is (-6, 0) and x intercept of line B is (3, 0)
