Answer:
5x
Step-by-step explanation:
If the blank were to be occupied with 5x there would be no solutions
Observe...
5x - 8 = 5x + 2
* subtract 5x from each side *
5x - 5x cancels out
5x - 5x cancels out
we're left with -8 = 2
which is not true
Hence if the blank = 5x the equation will have no solution
A rock is dropped from a height of 88.6 m and falls toward Earth in a straight line. In t seconds the rock falls 4.9t2 meters.
Answer:
The average speed is 9.8 meter per second in the first two seconds
Step-by-step explanation:
Complete Question
What is the average velocity of the rock in first 2 secs?
Solution
Distance travelled in first two seconds
[tex]4.9 t^2 = 4.9*2*2 = 19.6[/tex] m
Average speed = [tex]S2-S1/2 = 19.6-0/2 = 9.8[/tex] meter per second
Solve for x by factoring
Answer:
x = 5
Step-by-step explanation:
The area of the rectangle can be found by multiplying length x width:
Total Area = 55:
Length = x + 6
Width = x
Set the equation:
(x)(x + 6) = 55
First, distribute x to all terms within the parenthesis:
(x)(x + 6) = x² + 6x = 55
Next, set the equation equal to 0. Subtract 55 from both sides of the equation:
x² + 6x (-55) = 55 (-55)
x² + 6x - 55 = 0
Then, solve for x. Find factors of x² and -55 that, when combined, will result in 6x:
x² + 6x - 55 = 0
x 11
x -5
(x + 11)(x - 5) = 0
Then, solve each individual parenthesis:
(x + 11) = 0
x + 11 (-11) = 0 (-11)
x = -11
(x - 5) = 0
x - 5 (+5) = 0 (+5)
x = 5
Note, however, that a side cannot have a negative measurement. Therefore, x = 5 is your only answer.

According to question,
= 8x² + 6x - 2 = 228
= 8x² + 6x - 230 = 0
= 2(4x² + 3x - 115) = 0
= 2(4x² + 23x - 20x - 115) =0
= 2(x(4x +23) -5(x - 23) )= 0
= 2((x-5)(4x+23)) = 0
x = 5 , x = -23/4
let x = 5
so length 4x - 1
= 4 × 5 - 1
= 19 ft
width = 2x + 2
= 2 × 5 + 2
= 22 ft

Jim rented a truck for one day. There was a base fee of S 15.95, and there was an additional charge of 87 cents for each mile driven. Jim had to pay $189.08 when he returned the truck. For how many miles did he drive the truck?
Answer: I assume you are trying to find the
number of miles driven.
He paid $18 of which $15.95 was
the flat fee.
18.00
- 15.95
---------
$2.05 is the amount paid for mileage.
This is 205 cents for mileage
at 71 cents per mile. Divide
205 by 71 to get the miles driven.
205/71 = 2.9 miles.

For C it's y= 1.5x and D is y=2/3x
Answer:
y = 1.5x + 0 or y = 1.5x
Step-by-step explanation:
=> First lets find the slope:
Slope: Change in y / Change in x
Change in y = +15
Change in x = 10
Slope = 15/10 or 1.5
=> Now lets find the, y-intercept:
We know that y-intercept is the y-value when x = 0
So we can say:
y = 1.5x
y = 1.5(0)
y = 0
Therefore y-intercept = 0
Final equation: y = 1.5x + 0 or y = 1.5x

lacy work 15 hours last week she was paid $127.50 what is your hourly pay
Given:
Lacy work 15 hours last week and she was paid $127.50.
To find:
The hourly pay of Lacy.
Solution:
We have,
15 hours pay = $127.50
To find the hourly pay of Lacy, we need to divide total pay by number of hours.
[tex]\text{Hourly pay}=\dfrac{\text{Total pay}}{\text{Number of hours}}[/tex]
[tex]\text{Hourly pay}=\dfrac{127.50}{15}[/tex]
[tex]\text{Hourly pay}=8.5[/tex]
Therefore, the hourly pay of Lacy is $8.50.

Calista worked all summer to save for spending money while she is away for college. She goes off to college with $3920 in her savings account. She wants to have at least $500 left in her account at the end of her 36-week school year. Write an inequality to represent this situation.
Answer:
3920 - 36x ≤ 500
Step-by-step explanation:
Calista worked all summer to save for spending money while she is away for college. She goes off to college with $3920 in her savings account. She wants to have at least $500 left in her account at the end of her 36-week school year. Write an inequality to represent this situation.
Let the amount of money spent in 36 weeks = x
At least = Less than or equal to = ≤
$3920 - 36x ≤ $500

Answer:
Its gonna be a 50/50 on the coin and 20/100 chance for the spinner
Answer:
5 outcomes for the spinner and a 50/50 chance for the coin
Step-by-step explanation:
for the spinner, there are five numbers, 1,2,3,4, and 5. so, there is a 1/5 chance or you could also say there is a 20/100 chance. For the coin, there are two sides and 100 divided by 2 is 50 therefore, there is a 50/50 chance

How do you graph the polar curve r=5cosθ? Drag an equation, variable, or phrase into each box to correctly complete the statements.
Answer:
See graph below
Step-by-step explanation:
The equation r=5cosθ basically means the graph is going to be a circle with a radius of 5/2=2.5 to the right on the horizontal axis since it's cosine.
To graph the function r=5cosθ, we graph the function f(x) = 4cos(x), such that functional values are used as the corresponding values of θ and a radius of 2.5
How to graph the function?The function is given as:
r=5cosθ
The above means that, we want to graph the function f(x) = 4cos(x), such that functional values are used as the corresponding values of θ.
The radius r is calculated using;
r = 5/2
r = 2.5
Hence, the graph of r=5cosθ has a radius of 2.5

In parallelogram ABCD, AE = 2x - 10 and EC = 8x - 70. Find x.
x =??
Answer:
x = 10
Step-by-step explanation:
According to Midpoint of a segment theorem we can say that AE = EC
So,
2x - 10 = 8x - 70
=> First subtract 2x from each side of "="
-10 = 6x - 70
=> Now add 70 to both the sides.
60 = 6x
=> Lastly divide both sides of "=" by 6
10 = x
