Put your answer in fully reduced form.
Answer:
1/3
Step-by-step explanation:
(2-(-1))/(6-(-3)) = 3/9 = 1/3
Answer:
y=1/3x
Step-by-step explanation:
Find the slope: 2-(-1)
6-(-3)
slope = 1/3
Point Slope Form: y-2= 1/3 (x-6) plug one of the coordinates into the equation
y-2= 1/3x -2

What does it mean for a point to be a solution to a linear equation?
For example, if I say, "(2,5) is a solution to the equation (y=2x+3)," how could you check my claim?
Answer:
In your equation y=2x+3 and you used 2 [from your point (2,5) ] as the value of x, then y=2(2)+3=7.
now if you plotted this, that point would be (2,7), not (2,5).
So (2,5) is not the solution.
(2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].
Let be linear equation [tex]y = 2\cdot x + 3[/tex], if we know that [tex](x,y) = (2, 5)[/tex] and we need to check is [tex]2\cdot x + 3 = 5[/tex] by algebraic means, that is, we solve for [tex]x[/tex]:
[tex]2\cdot x + 3 = 5[/tex]
[tex]2\cdot x = 2[/tex]
[tex]x = 1[/tex]
Hence, we conclude that (2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].

An athlete eats 55 grams of protein per day while training. How much is this in milligrams?
Answer:
55,000 milligrams
Step-by-step explanation:
........
Answer:
55,000 milligrams (mg) is equal to 55 grams (g)
Step-by-step explanation:
(55 g/1 )* (1000 mg/1 g)
Multiply the top to get 55,000 and the bottom to get 1.
55,000/1
The gram units cancel out, leaving you with milligrams.
55,000 mg

The old bag of marbles contains 4 blue and 3 red marbles. If you were to double the number of red and blue marbles to create a NEW bag, would the chance of pulling out a blue marble be the same as pulling a blue marble from the old bag? (this is for math class by the way-)
Answer:
The chance will be the same (4/7)
Step-by-step explanation:
Old bag
p(blue)=4/7
New bag
p(blue)=8/14=4/7
The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.

OA. It is the graph of fx) translated 3 units to the left.
OB. It is the graph of f(x) translated 3 units down.
OC.
It is the graph of fx) translated 3 units up.
OD. It is the graph of f(x) where the slope is decreased by 3.
Answer:
It is the graph of f(x) translated 3 units down.
Step-by-step explanation:
The graph of r(x) = x was translated 3 units down to form g(x) = r(x) - 3.
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Translation is the movement of a point either up, left, right or down.

Find the area for the given circle. Round to the nearest tenth.
113.0 ft^2
124.8 ft^2
37.7 ft^2
452.2 ft^2
Answer:
The answer is 113.0 ft^2
Step-by-step explanation:
To find the area you do pi times the radius squared, so that would be pi times 36. which equals 113.0 ft^2.
The area of a given circle is 113.0 square feet. Therefore, option A is the correct answer.
What is area of a circle?The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.
Given that, the diameter of circle is 12 feet.
Here, radius = 12/2
= 6 feet
Now, area of a circle = 3.14×6²
= 3.14×36
= 113.0 square feet
Therefore, option A is the correct answer.

Write in Slope Intercept form
Answer:
its the first choice
Step-by-step explanation:
Answer:
y= -3/5x +5
Step-by-step explanation:
Step one - find where the line is intercepting. In your case this is at positive 1.
Next step is to check the change of the slope - directio. The line goes up to the positive Y access and to the left of the negative X access.
That leads to a negative slope.
Respectavley the only posible answer on this question is
y= -3/5x +5
Good luck.

F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?
Answer:
f(-2) = 0
Step-by-step explanation:
Given that:
f(x) = bx^2 + 32
f(2) = b(2)^2 + 32
f(2) = 4b + 32
f(2) = 4b = -32
f(2) = b = -32/4
f(2) = b = -8
Thus;
f(-2) = -8(-2)^2 + 32
f(-2) = -8(4) + 32
f(-2) = -32 + 32
f(-2) = 0
