What is the slope of the line shown below?
Answers
Answer: -4
Step-by-step explanation:
If you are given a problem like this with two points, the easiest way to find the slope is using the equation [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex] with points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex].
In this problem, by looking at the graph, you can identify the points (0, 10) and (5, -10)
Let's label these numbers:
x1 = 0x2 = 5y1 = 10y2 = -10Now, plug these numbers into the formula above. That gives you [tex]\frac{-10-10}{5-0}[/tex].
-10 - 10 = -20 and 5 - 0 = 5, which gives you a fraction of [tex]\frac{-20}{5}[/tex], which can be simplified down to -4.

Zeke is racing his little brother Niko. They are running a total of 30 yards and Zeke gives Niko a 12 yard head start. Zeke runs 2 yards every second but Niko only runs 1 yard every 2 seconds. If x represents the number of seconds they have been racing and y represents the distance from the start line then:
Fill out the table below for various distances that Zeke and Niko are from the start line at the given times
X (sec) Zeke Distance (yd) Niko Distance (yd)
0 0 12
2
6
Answers
Answer: Zeke will catch up with Niko at 16 yards from the start line, y = 16 yards.
Zeke will catch up Niko after 8 seconds, x = 8 seconds.
Step-by-step explanation: i) distance to be run = 30 yards
ii) Niko has a head start of 12 yards.
iii) speed of Zeke = 2 yards / second
iv) speed of Niko = 1 yard every 2 seconds = 0.5 yard / second
v) x represents the number of seconds they have been racing.
vi) y represents the distance from the start line.
vii) the time at which Zeke catches up with Niko will be given by
Therefore 2y - 24 = 0.5y 1.5 y = 24 y = 24 / 1.5 = 16 yards
Therefore x = 16 /2 = 8 seconds
I have to repost this because I was giving wrong answers. The instructions are to complete each proof using the properties of equality
Answers
Answer and Step-by-step explanation:
We are given:
[tex]\frac{2y-1}{-3} = 5[/tex]
First, we multiply both sides by -3.
2y - 1 = 15
Now we add 1 to both sides.
2y = 16
Finally, we divide by 2 to each side.
y = 8
We are given:
2x + 30 = -4(5x -2)
First we distribute the -4 to 5x and -2.
2x + 30 = -20x + 8
Now we subtract 8 from both sides.
2x + 22 = -20x
Now we subtract 2x from both sides.
22 = -22x
Finally, we divide by -22 to both sides.
-1 = x

2y - 1 = 15 Multiplication Property of Equality

While measuring a wire a 5cm wire, a construction worker measured it 5.2 cm by mistake. What is the percent error?
Answers
Answer:
4%
Step-by-step explanation:
Actual length of wire = 5 cm
The measured length of wire = 5.2 cm
We need to find the percent error in the measurement of the length of wire. It can be calculated as follows :
[tex]\%=\dfrac{\text{measured length-actiual length}}{\text{actual length}}\times 100\\\\=\dfrac{5.2-5}{5}\times 100\\\\=4\%[/tex]
So, the required percent error is 4%.

What is 1/4 exponent 3 equal to in fraction form. Help as soon as possible plz
Answers
Answer:
Step-by-step explanation:
(1/4)^3=1^3/4^3=1/64
Here we need to use the exponent property:
[tex](\frac{a}{b} )^n = \frac{a^n}{b^n}[/tex]
Using this, we will see that the given expression is equal to:
[tex]\frac{1}{64}[/tex]
We start with:
[tex](\frac{1}{4} )^3[/tex]
Now we can use the above property to rewrite this as:
[tex](\frac{1}{4} )^3 = \frac{1^3}{4^3}[/tex]
Now we know that:
1^3 = 1
4^3 = 4×4×4 = 16×4 = 64
Now we can replace these in the above expression to get:
[tex](\frac{1}{4} )^3 = \frac{1}{64}[/tex]
