What will be the linear equation for the shown table?
Answers
Answer:
y=2x+5
Step-by-step explanation:
To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)
So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2
Slope = 2, now find b
So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5
Put it all together y = 2x + 5

Graph this: y = 2sIn(x) - 3
Insert picture of graph
Answers
Answer:
We have the function:
f(x) = 2*sin(x) - 3
To graph this type of functions is useful to understand the parts of the function.
A general one is written as:
g(x) = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency.
p is the phase
M is the midline.
Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3
Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:

Answers
Answer:

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $7143 to rent trucks plus an additional fee of $175.75 for each ton of sugar.
Answers
Answer:
14 tons of sugar
$9603.5
Step-by-step explanation:
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Let
x = ton of sugar
Company A:
7500 + 150.25x
Company B:
7143 + 175.75x
1. Equate company A and company B
7500 + 150.25x = 7143 + 175.75x
7500 - 7143 = 175.75x - 150.25x
357 = 25.50x
x = 357/25.50
x = 14 tons of sugar
2. Cost when both companies charge the same
Company B:
7143 + 175.75x
= 7143 + 175.75(14)
= 7143 + 2460.5
= 9603.5
Company B = $9603.5
Company A:
7500 + 150.25x
= 7500 + 150.25(14)
= 7500 + 2103.5
= 9603.5
Company A = $9603.5

You charge $2 per square yard to paint.Which equation can you solve to find the amount you will charge to paint a triangular wall with a base of 4 yards and a height of 6 yards?
Answers
Answer:
2(1/2 x 4 x 6) = x
expaination:
area of triangle = 1/2 x 2 x 6 sq yards
multiply by $2/sq yard
Answer: $24
Step-by-step explanation:
The formula for a triangle is 1/2 times base times height
so 0.5 x 4 x 6
0.5 x 4 = 2
2 x 6 = 12
12 x $2 = 24
so you charge $24 dollars

A rectangular prism has a volume of 80 cubic feet. The length of the prism is 8 feet and the height of prism is 4 feet. What is the width of the prism?
Answers
Answer:
2.5
Step-by-step explanation:
8 times 4 is 32, and 80/32 is 2.5. When you have to find another measurement and you know 2 of them, you just have to divide the total of the 2 measurements with the volume. it would be 2.5 feet as the height.

Find the area of the yellow region.
Round to the nearest tenth.
5 ft
Area = [ ? ] ft2
Answers
Answer:
yellow area = 5.37 ft²
Step-by-step explanation:
area of square = L x W = 5 x 5 = 25 ft²
radius = 2.5 ft
area of circle = PiR² = (3.14)(2.5²) = 19.63 ft²
25 - 19.63 = 5.37 ft²
The area of the yellow region is 5.375 square feet.
What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
Given that, the side of a square = 5 feet and radius of a circle = 2.5 feet.
Here, area of a square = side²
= 5²
= 25 square feet
Area of a circle = πr²
= 3.14×2.5²
= 19.625 square feet
So, the area of the yellow region = 25-19.625
= 5.375 square feet
Therefore, the area of the yellow region is 5.375 square feet.

Brian earns $5 per hour babysitting. He makes a graph and plots what he
earns for different numbers of hours. He places the number of hours he
works on the x-axis and his earnings on the y-axis. What is the slope of the
line that Brian graphs?
Answers
Answer:
The slope of the line is 5
Step-by-step explanation:
When we talk of the slope of a straight line graph, we refer to the rate at which the values on the y-axis changes as a ratio of the changes we have on the x-axis
Now, from the question, number of hours is placed on x-axis, while we have the amounts on the y-axis
having $5 per hour means the rate of change of what is earned to number of hours worked is 5 and this is the slope of the line

True or False. To find the missing side length in the diagram, use the Pythagorean Theorem.
Answer: A
Answers
The Pythagorean theorem is a^2 + b^2 = c^2 where a^2 and b^2 are the two legs of the triangle (two sides connected by the right angle) and c is the hypotenuse (longest side, opposite the right angle).
To solve using the Pythagorean theorem, plug in sides AC and CB into a and b, then solve for c.
23^2 + 31^2 = c^2
529 + 961 = c^2
c^2 = 1490
c = √1490 = 38.601

Consider the line 7x+8y=-5.

What is the slope of a line parallel to this line?
Answers
Answer:
Step-by-step explanation:
7x + 8y = -5
8y = -7x - 5
Divide the whole equation by 8
[tex]\frac{8y}{8}=\frac{-7x}{8}-\frac{5}{8}\\\\y =\frac{-7}{8}x-\frac{5}{8}[/tex]
Parallel lines have same slope
Slope of the parallel line = (-7/8)
Slope of the line perpendicular to this line = -1/m = -1 ÷ (-7/8)
[tex]= (-1)*\frac{8}{-7}\\\\= \frac{8}{7}[/tex]
