Answer:
y=-6x+36
Step-by-step explanation:
у + 6x — 36 = 0
-add 36 to both sides
y+6x=36
-subtract 6x from both sides
y=36-6x or y=-6x+36
-This should be the correct answer

x = 15
what does The cube of the sum of a number and 8 look like
Answer:
x+y = 8
x3 + y3 = 20 ...this system represents the given statements.
Use the factoring rule for sum of cubes:
(x+y)(x2+xy+y2) = 20. By substituting for the linear factor, you get
8(x2+xy+y2) = 20 or 2(x2+xy+y2) = 5.
Now substitute for y; y = 8-x and you will have a (maybe not so nice) quadratic equation in x, which you can solve by Quadratic Formula (if factoring isn't obvious).
you get to finish this job.

Equivalent or Not?
Sarah thinks that the following
expressions are equivalent:
2x + 3 = x/2 + 4
Is she correct? If so, prove that these
two expressions are equivalent. If not,
explain what errors she made.
Answer:
equivalentStep-by-step explanation:
2x + 3 = x/2 + 4
2x - x/2 = 4 - 3
3x/2 = 1
x = 1 (2) / 3
x = 2/3
substitute the value of x=2/3 back into the equation:
2(2/3) + 3 = (2/3)/2 + 4
4/3 + 3 = 1/3 + 4
13/3 = 13/3 both are equal if x=2/3Find the values of x and y
Answer:
You can find out x and y by solving these equations simultaneously.
First case:
according to the opposite angle theorem, (18y+5)° = (10x-61)°
Now let's simplify them;
18y-10x = -66
y= (10x-66) ÷ 18......................(i)
Second case:
Around that centre, it is always 360°.
And the angle opposite to the (x+10)v is also (x+10)°.
And sum of these 4 angles is 360°.
(18y+5)° + ( 10x-61)° + (x +10)° + (x +10)°= 360°
18y + 12x -36 = 360°
18y + 12x = 396...........................(ii)
Now replace the value of y from (i) into (ii):
18 ((10x-66) ÷ 18) +12x =396
(10x-66) +12x = 396
22x -66 = 396
22x = 462
x = 21
Now let's put this value of x into our equation (i):
y= (10(21)-66) ÷ 18
y= 8

Joe walks 9.5 inches every second what is the first step of finding mph?
Answer:

Step-by-step explanation:
this is the only thing i do not understand about geometry
Answer:
see explanation
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{20}[/tex] ( multiply both sides by 20 )
20 × tan40° = opp , thus
opp = 20 × 0.839 ≈ 16.78 , then
height of traffic light = 16,78 + 5 = 21.78 ft
------------------------------------------------------------------------
Using the tangent ratio in the right triangle
tan42.71° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{150}{d}[/tex] ( d is the distance between store and bank )
Multiply both sides by d
d × tan42.71° = 150 ( divide both sides by tan42.71° )
d = [tex]\frac{150}{tan42.71}[/tex] = [tex]\frac{150}{0.923}[/tex] = 162.5 m

When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
3y+7x+18
———————— • 3 = 0 • 3

Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
3y+7x+18 = 0
Equation of a Straight Line
5.2 Solve 3y+7x+18 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3y+7x+18 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -6/1 so this line "cuts" the y axis at y=-6.00000
y-intercept = -18/3 = -6
Calculate the X-Intercept :
When y = 0 the value of x is -18/7 Our line therefore "cuts" the x axis at x=-2.57143
x-intercept = -18/7 = -2.57143
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -6.000 and for x=2.000, the value of y is -10.667. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -10.667 - (-6.000) = -4.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -4.667/2.000 = -2.333
Geometric figure: Straight Line
Slope = -4.667/2.000 = -2.333
x-intercept = -18/7 = -2.57143

Cherries are on sale at the grocery store at a price of $5 for 2 pounds. Oscar buys 3
pounds. If he is charged the sale price for the cherries, how much will Oscar pay?
Answer:
$7.5 = 3 pounds
Step-by-step explanation:
1. If $5 is equal to 2 pounds of cherries, you want to find what 1 pound of cherries cost. You should divided 5 by 2 and 2 by 2 to find what 1 pound of cherries cot.
2. That means that 1 pound of cherries cost $2.5.
3. Now we want to find how much money 3 pounds cost, so you should multiply the 2.5 and the 1 by 3.
4. Now that gets you to $7.5 for 3 pounds of cherries.s
What is the equation in point-slope form of the line that passes through the point (-4, 5) and has a slope of 23?
Answer:
The answer is
[tex] \huge y - 5 = 23(x + 4) \\ [/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the points are (-4, 5) and a slope of 23
We have the final answer as
[tex]y - 5= 23(x + 4)[/tex]

A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 77 feet per second. The elevator for the miners descends 1313 feet per second. One day, the equipment elevator begins to descend. After 2929 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 1616 seconds? At that time, which elevator is deeper?
Answer:
The position of the equipment elevator is 315 feet deep.
The position of the elevator of the miners is 208 feet deep.
At that time, the equipment elevator is deeper.
Step-by-step explanation:
Observation: Seems the numbers are doubled. 77 instead of 7; 1313 instead of 13; 2929 instead of 29; and 1616 instead of 16.
Hence, the question is:
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 7 feet per second. The elevator for the miners descends 13 feet per second. One day, the equipment elevator begins to descend. After 29 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 16 seconds? At that time, which elevator is deeper?
Step-by-step explanation:
From the question,
For the equipment elevator
Speed= 7 feet/second
For the elevator of the miners,
Speed= 13 feet/second
To determine the positions of each elevator relative to the surface, we will determine the distance each of the elevator descends.
From the formula
Speed= Distance / Time
Then,
Distance = Speed × Time
From the question,
The equipment elevator begins to descend and after 29 seconds, the elevator for the miners begins to descend. To determine the position of each elevator after another 16 seconds. That is, the equipment elevator descends for a total of (29+16) seconds and the elevator of the miners descends for 16 seconds.
For the equipment elevator
Speed= 7 feet/second
Time = 29 + 16 seconds = 45 seconds
From, Distance = Speed × Time
∴ Distance = 7 feet/second × 45 seconds
Distance = 315 feet
Hence, the position of the equipment elevator is 315 feet deep.
For the elevator of the miners
Speed = 13 feet/second
Time = 16 seconds
Distance = Speed × Time
∴ Distance = 13 feet/second × 16 seconds
Distance = 208 feet
Hence, the position of the elevator of the miners is 208 feet deep.
At that time the equipment elevator is deeper.
