Answer:
y=-1/3x+10
Step-by-step explanation:
y=3x+1
The line perpendicular would have a negative reciprocal of the slope of 3 which means that you would add a negative sign and then flip 3/1 into 1/3 resulting in -1/3 as the slope.
To find the line that passes through the point (6,8) you would plug the values into the equation y=mx+b
m=-1/3x as found above
6 is the x-value and 8 is the y-value
8=(-1/3)(6)+b
8=-2+b
Add 2 on both sides and you get b to equal 10
Write an equation that can be used to describe the relationship between x and y shown in the graph in the image
Answer:
[tex]y=-2x+3[/tex]
Step-by-step explanation:
Equation of straight line in slope intercept form is given as
[tex]y=mx+b[/tex]
Here
Slope of line m=-2 (for every one step on x-axis line going down 2 step on y-axis)
y-intercept b=3
[tex]y=-2x+3[/tex]
During a hockey game, the puck slid 27meters across the ice rink as it was chased by a hockey player skating at 9.5 meters per second. The puck slid that distance in 1.5seconds at a steady speed. What was the puck's speed
Answer:
Speed of Puck is 18 m/s
Step-by-step explanation:
Mathematically;
speed = distance/ time
The puck traveled a distance of 27 m in 1.5 seconds
The speed of the puck is thus;
27/1.5 = 18 m/s

The length and width of a rectangle
added together is 124. If the width is
subtracted from the length it equals 32.
Find the length and width of this rectangle.
Answer:
The length of rectangle is 78 and width is 46
Step-by-step explanation:
Let l be the length of rectangle and w be the width of rectangle
Then according to given statement
"The length and width of a rectangle added together is 124"
[tex]l+w = 124[/tex] Eqn 1
And
[tex]l-w = 32[/tex] Eqn 2
The equation form a system of linear equation in two variables. We can use different methods to solve he system.
We will use the elimination method
Adding equation 1 and equation 2
[tex]l+w+l-w = 124+32\\2l = 156\\\frac{2l}{2} = \frac{156}{2}\\l = 78[/tex]
Putting l = 78 in equation 1
[tex]78+w = 124\\w = 124-78\\w = 46[/tex]
Hence,
The length of rectangle is 78 and width is 46

Given that 1 inch = 2.54 cm, how many centimeters are there in 7 feet? Answers may be written using decimals form and should be rounded to the nearest hundredth when necessary
Answer:
There are 213.36 centimeters in 7 feet.
Step-by-step explanation:
It is given that:
1 inch = 2.54 cm
We have to find centimeters in 7 feet.
We will convert feet to inches.
1 feet = 12 inches
7 feet = 12*7 = 84 inches
Now,
1 inch = 2.54 cm
84 inches = 2.54 * 84
84 inches = 213.36 cm
Therefore,
There are 213.36 centimeters in 7 feet.
Write an equation for the translation of [tex]y\frac{3}{x}[/tex] that has the asymptotes x = 6 and y = -6.
Show all your steps, then graph it. (Be sure to link the graph with your steps.)
a.) [tex]y=\frac{3}{x+6}-6[/tex]
b.) [tex]y=\frac{3}{x-6}+6[/tex]
c.) [tex]y=\frac{3}{x-6}-6[/tex]
d.) [tex]y=\frac{3}{x+6}+6[/tex]
______________________________
1.) Substitute x, y, and general form using the formulas:Formula for x: [tex]x=d=6[/tex]Formula for y: [tex]y=k=-6[/tex]Formula for general form y: [tex]y=\frac{a}{x-d}+k=y=\frac{3}{x-6}+(-6)[/tex]Note:
- When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.
Equation at the end of Step 1:
[tex]y=\frac{3}{x-6}+(-6)[/tex]2.) Simplify the d and k forms:[tex]y=\frac{3}{x-6}+(-6)=y=\frac{3}{x-6}-6[/tex]Note:
- The x(d) stays the same since the 6 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.
- The y(k) changes from [tex]+(-6)[/tex] to [tex]-6[/tex] because when a [tex](+)[/tex] and [tex](-)[/tex] are next to each other, the rule is [tex]+<-[/tex]. The Minus always wins in this type of problem situation.
So the answer is c, [tex]\bold{y=\frac{3}{x-6}-6}[/tex].
