Step-by-step explanation:
Write the equation of the line in fully simplified slope-intercept form.
Answer:
y=-1/2x-1
Step-by-step explanation:
the slope intercept form is y=mx+b
m=slope
b=y intercept (where the line crosses the y axis)
to find slope you do rise over run or rise/run
the rise of you slope is -1, and the run of your slope is 2, meaning your slope is -1/2
the line crosses the y axis at point -1
plug what you find into the slope intercept form, and you get y=-1/2x-1

Aisha measures the length of a sheet of paper and finds that it is 29 cm long. The label on the package indicates that the paper length is 32 cm. Calculate the percentage error in the measurement.
Answer:
just do the step by step and you'll probably get it because it's quite simple but hard for me to explain so just read this!
Step-by-step explanation:
In making any measurement, the chances are that our results will not be absolutely accurate. We can often compare our results with some standard or accepted value to see how closely they agree. But how much error can be allowed before the result becomes meaningless?
As you may guess, the amount of error that is acceptable varies with the situation. Suppose you measure the distance on a map between your Scarsdale and Mamaroneck and you get a result of 5 miles. If the actual distance is 5 1/2 miles, the chances are this error will have no effect on the trip between the two towns. But if the same degree of error existed in the calculations used to send astronauts to the moon, those people would be in big trouble!
Percentage Error = measured value - accepted value x 100%
accepted value
Suppose, you measured the length of a table and obtained a measurement of 202 cm. A friend also measures the table and obtains a result of 198 cm. To calculate the percentage error in each of the measurements, you need to know the "correct' or “accepted value” of the length of the table. After consulting the manufacturer’s catalog, you find that the table's length is listed as 200 cm in length. This will be used as the accepted value in our calculation.
The calculations of percentage error for the two measurements are shown below. Both measurements show an error of 1%. Your friend has made a measurement which is on the low side of the accepted value and is therefore, negative. You, on the other hand, have made an error on the high side of the accepted value and it is positive.
I dont know the answer but I hope this helped!

Write an equation in which the quadratic expression 2x^(2)-2x-12equals 0. Show the expression in factored form and explain what your solutions mean for the equation. Show your work.
Answer:
Answer:
Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:
This results in x = 3 and x = -2. The equation is true for these two x-values.

How many 1/4 inch cubes does it take to fill a box with width 1 1/4, length 3 3/4 inches and height 2 1/4 inches?
Answer:
4 of those 1/4th inches wouldnt it ?
Step-by-step explanation:
Volume of the box: 1 1/4 x 3 3/4 x 2 1/4 = 10 33/64 cubic inches.
Volume of cube : 1/4 x 1/4 x 1/4 = 1/64
Number of cubes: 10 33/64 / 1/64 = 673 cubes

David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left?
?
__
?
what percent?________%
Answer:
200/500=2/5
40%
Step-by-step explanation:
If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.
Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500
Then simplify=200/500 divided by 100/100 equals 2/5.
Then to get it to a percentage divide 2 by 5 which equals .40
Then convert to a percentage 40%
g÷ 5/8 =1
basically its asking what divided by 5/8 = 1
Answer:
5/8 divided by 5/8 = 1
Step-by-step explanation:
First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.
[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]
Now, multiply both sides by 5 to get rid of the fraction.
[tex]8g = 5[/tex]
divide both sides by 8
[tex]g = 5/8[/tex]

Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.
I'm bad at transitions so here's the math:
(y2-y1)/(x2-x1)
((-10)-(-9))/(4-2)
-1/2 ------> Thats "m".
SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE
The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.
Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.
y=mx+b
m=-1/2
b=-8
y=-1/2x+-8-----> y=-1/2x-8

MAGIC

The perimeter of a rectangular garden is 37.5 feet. The width is x, and the length is 15 ft. Use the equation 2(x + 15) = 37.5 to determine the width, in feet, of the garden?
Answer:
2.5
Step-by-step explanation:
37.5/15=2.5
Answer:
11.25
Step-by-step explanation:
first what u do is u just make 2(x+15)=37.5 into 2x+15=37.5
and then u do 2x=37.5-15
that will give u 2x=22.5
then u do this x=22.5/2
and x = to 11.25

Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180
Answer:
because its a straight line
Step-by-step explanation:
Answer:
Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.
(2x-7)+(x+25)+(3x+12)=180
6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.
6x=150 subtract 30 from both sides of the equation
x=25.

A horizontal slice through a three-dimensional solid produces the two-dimensional shape below. (The shape is a square)
Which one of the following solids produces this two-dimensional shape when sliced horizontally?
Is it A, B, C, or D????
Answer:
C
Step-by-step explanation: i am doing same thing you are doing rn
You can use the fact that a horizontal slice is like you're slicing the given shape parallel to ground.
The correct shape which will produce a square when sliced horizontally is ""D" figure which as 4 sides.
What is a square?A square is a closed figure formed by end to end joined equal length four line segments such that all the adjacent lines are perpendicular to each other.
A square has 4 sides.
What is horizontal slicing?Horizontal refers to something that goes parallel to ground level. Of course it depends on from where you see that thing.
When you slice an object horizontally, you cut it parallel to ground.
How to know which of the given solid will produce square?Since a square has 4 equal sides, all perpendicular to each other, we see that only 4th object has 4 sides.
Thus, the fourth solid, named D is the solid that can produce square when sliced horizontally.
