Step-by-step explanation:
Step 1: Define
v² = u² + 2as
v = 5
u = 2
s = 7
Step 2: Evaluate
Subtract u² on both sides: v² - u² = 2asDivide 2s on both sides: (v² - u²)/(2s) = aRewrite: a = (v² - u²)/(2s)Substitute: a = (5² - 2²)/(2 · 7)Exponents: a = (25 - 4)/(2 · 7)Multiply: a = (25 - 4)/14Subtract: a = 21/14Simplify: a = 3/2Which of the following values does not satisfy the inequality X - 7 > 12?
A 11
B 33
C 22
D 44
Answer:
We conclude that when we put x = 11, it does not satisfy the inequality.
Hence, option (A) is correct.
Step-by-step explanation:
Given the inequality
x - 7 > 12
Any value which makes the inequality FALSE would be the value that not satisfy the inequality.
Putting x = 11 in the inequality
x - 7 > 12
11 - 7 > 12
4 > 12
FALSE!
Reason: 4 can not be greater than 12
Putting x = 33 in the inequality
x - 7 > 12
33 - 7 > 12
26 > 12
TRUE!
Reason: 26 is indeed greater than 12
Putting x = 22 in the inequality
x - 7 > 12
22 - 7 > 12
15 > 12
TRUE!
Reason: 15 is indeed greater than 12
Putting x = 44 in the inequality
x - 7 > 12
44 - 7 > 12
37 > 12
TRUE!
Reason: 37 is indeed greater than 12
Therefore, we conclude that when we put x = 11, it does not satisfy the inequality.
Hence, option (A) is correct.

A seal has 1,500 nerves per whisker. That is 101010 times as many as a rat has. How many nerves per whisker does a rat have?
Answer:
0.01485...
Step-by-step explanation:
Given:
A seal has 1,500 nerves per whiskerThis is 101,010 times as much as a rat has per whiskerWe will:
Divide the number 1,500 by 101,0101,500 ÷ 101,010 = 0.0148500149
0.0148500149 ⇒ 0.01485 when rounded
Your answer: 0.0148500149, 0.01485 when rounded

What is the coefficient of x 8+5x-y
Answer:
The coefficient is 5.
Step-by-step explanation:
The coefficient is the number that comes before the variable, 8 wouldn't be a coefficient because it doesn't have a variable, so therefore the correct answer is 5.
I hope I could help :)
The solution is 5
The coefficient of the equation A = 8 + 5x - y is 5
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
The value of A is
A = 8 + 5x - y be equation (1)
Let the coefficient be = c
The coefficients are the numbers by which the variables in an equation are multiplied
So , the coefficients of the equation is 5
Therefore , the value of c = 5
Hence , the coefficient of the equation is 5

Write two like terms using whatever variable(s) you’d like. Be sure to include exponents. Explain why these are like terms.
Answer: 10x^2+7x^2= 17x^2
Step-by-step explanation:
This binomial is alike because they hold the same value of exponent which is why they can be combined, since you add the coefficient of the variables leaving the exponents unchanged.

For a play, the ticket prices were $5.00 per child and $8.50 per adult. the children bought 100 more tickets than the adults. the total box office income was $905.00. how many tickets of each type were sold?
Using the concept of linear equations, number of tickets bought by the children and adults are 130 and 30 respectively.
What is Linear Equation in one variable?The linear equation in one variable is written as ax + b = 0, where a and b are two integers and x is a variable. This equation has only one solution.
Given that,
Ticket price per child = $5.00
Ticket price per adult = $8.50
Total box office income = $905.00
Let the tickets bought by the adults be x.
Then, tickets bought by the children will be x + 100.
Here, x is a variable.
Linear equation will be:
8.50x + 5(x + 100) = 905.00
8.50x + 5x + 500 = 905.00
13.50x + 500 = 905.00
13.50x = 905.00 - 500
13.50x = 405.00
x = 405.00/13.50
x = 30
So, the tickets bought by the adults = 30
And tickets bought by the children = x + 100
Tickets bought by the children = 30 + 100
Tickets bought by the children = 130

Answer:
8 + 2w
Step-by-step explanation:
⇒ Change all signs to addition (subtraction is the same as adding a negative):
5 + 3w + 3 + -w
⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:
5 + 3 + 3w + -w
⇒ Simplify:

Answer:
The number of times he visited the gym is 19 times.
Step-by-step explanation:
A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195, how many times did he visit the gym? Define Variable: Equation: Solve (Show all steps):
Let the number of times he visits the gym be represented as x
A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195,
The Amount he spends = $195
= $100 + $5 × x
$195 = $100 + 5x
5x = $195 - $100
5x = $95
x = 95/5
x = 19 times
Therefore, the number of times he visited the gym is 19 times.

Step-by-step explanation:
.......................
Answer:
3
Step-by-step explanation:
The formula of to calculate slope of a linear function is
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope and so lets take any two points from the table to calculate the slope. Lets take,
(0 , 4) and (1 , 7) and lets plug it in the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{7-4}{1-0}\\\\m=3[/tex]
So the slope of the function is 3

Step-by-step explanation:
Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.
