Answer:
B. 500
Step-by-step explanation:
the scale only measures increments of 1,000 pounds, e.g. its scale is 0 pounds, 1,000 pounds, 2,000 pounds, 3,000 pounds, etc.
What happens if something weighs exactly 1,500 pounds (or 500, 2500, 3500, etc)? The scale will measure either 1,000 or 2,000 pounds, so the maximum margin of error is ± 500 pounds.
Answer:
B

I TOOK A QUIZ WITH THE QUESTION GOT IT RIGHT
r(x) = -4x² + 5x1
r(-3) =?
Answer:
therefore when x = -3, r(x) = -51
Step-by-step explanation:
This is a function of r(x), so when it says r(-3), the x value is -3, so we have to find the value of r(x) when x=-3.
just plug in the x value in to the given equation
r(-3) = [tex]-4(-3)^{2}[/tex]+5(-3)
r(-3) = -4(9)+5(-3)
r(-3) = -36+-15
r(-3) = -51
therefore when x = -3, r(x) = -51
Answer: r(x) = -51
If the 1 is not a +1 or a -1
It is very unusual to have a 1 in that position.
Step-by-step explanation:
Substitute the value given (-3) in place of x, and evaluate the function.
r(-3) = -4(-3)² + 5(-3)
r(-3) = -4(9) - 15
r(-3) = -36 -15
r(-3) = -51
A line that passes through the points (−5, 7) (10, 1). Using the mx+b format
Answer:
y=2x-19
Step-by-step explanation:
I'm guessing you mean slope intercept form y=mx+b
If so, first you would have to find the slope of the line
To do that, use the formula y2-y1/x2-x1
Remember you can pick any coordinate pair for this
I will pick 1=y2 -5=y1 10=x2 and 7=x1
When I put that in the equation I get 1-(-5)/10-7
Overall I get 6/3, or 2
Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)
I will pick (10,1)
1=y and 10=x and 2=m
1=2(10)+b
this simplifies to 1=20+b
now subtract 20 from both sides and get -19 = b
Now you have your equation y=2x-19

Paul creates the diagram to help him factor 4x2 + x – 5 by using double grouping. His diagram is incomplete.
Which terms should Paul write in squares M1 and M2?
a) 5x and −4x
b) –5x and 4x
c) –2x and 10x
d) 2x and −10x
Answer:
5x and -4x
Step-by-step explanation:
Because Paul is looking for M1 and M2 in order to get a total that is +x and a product that is equal to -20x^2, we can see that 5x and -4x help Paul get the products he wants.
Answer:
A; 5x and −4x

Which function has a domain of all real numbers?
A. y=-x½+5 B. y=(2x)⅓-7 C. y=(x+2)¼ D. y=-2(3x)⅙?
Answer:
B.
Step-by-step explanation:
B. Because the others have exponents whose denominators are even so the results of , for example x^1/2, if x is negative is not defined.
For example:
For A, when x is -4, (-4)^1/2 is not real.
For B, when x = -4, (2*-4)^ 1/3 = -8^(1/3) = = -2.

what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
Answer:
The equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4
Step-by-step explanation:
We need to write equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
When the graph is shifted towards right h units the equation becomes f(x)=(x-h) using it for our scenario:
If x is shifted right 3 units it will become f(x)=|x-3|
When the graph is shifted down h units the equation becomes f(x)=x-h using it for our scenario:
and Shifted down 4 units the equation will become: f(x)=|x-3|-4
So, the equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4

4/5 divided by 1/3 / fraction
The solution (quotient) when [tex]\frac{4}{5}[/tex] is divided by [tex]\frac{1}{3}[/tex] is [tex]2\frac{2}{5}[/tex]
To determine the solution of 4/5 divided by 1/3,
First, let us write the fractions properly before carrying the division operation
That is,
[tex]\frac{4}{5}[/tex] divided by [tex]\frac{1}{3}[/tex]
Now, we will carry out the division operation
[tex]\frac{4}{5} \div \frac{1}{3} = \frac{4}{5} \times \frac{3}{1}[/tex]
Then,
[tex]\frac{4}{5} \times \frac{3}{1} = \frac{12}{5}[/tex]
[tex]= 2\frac{2}{5}[/tex]
Hence, the solution (quotient) when [tex]\frac{4}{5}[/tex] is divided by [tex]\frac{1}{3}[/tex] is [tex]2\frac{2}{5}[/tex]
