Answer:
x= 9.434
Step-by-step explanation:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)

Answer:
Your answer is infinitely many solutions
Step-by-step explanation:
To use elimination you have to get one of the variables to be the opposite of each other, so here you would do:
-2(2x+y = 7)
4x+2y= 14
You multiply the top by -2 to get the opposite of 2y, which is -2y. This in turn multiplies everything by -2 on the top solution giving us the top equation below.
-4x-2y = -14
+ 4x+2y = 14
--------------------
0 = 0
If you add those 2 solutions then you get 0 = 0, which is infinitely many solutions

The function h(n) = 8 - 3n represents the value of the nth term in a sequence.
What is the product of the 2nd and 5th terms of the sequence?
Answer:
aaaa
Step-by-step explanation:
Answer:
h(2) = 2
h(5) = -7
Step-by-step explanation:
h(n)=8-3n
h(1)=8-3(1) = 5
h(2)=8-3(2) = 2
h(5) = 8-3(5) = 8-15 = -7

Answer:
here, suppose the missing length be X
hy ^2 = (one side square )^2 +(Other side square)^2
29^2= X^2 + 21^2
841 = X^2 + 441
X^2 = 841 - 441
X^2 = 400
X = 20 .........taking square root both side
the value is missing side length is 20 .
evaluate tan-1 (1.6) giving your answer to the nearest degree
Answer:
58degrees
Step-by-step explanation:
Given
tan^-1(1.6)
= tan^-1(16/10)
= tan^-1(8/5)
= 57.99 degrees
Hence the value of tan^-1(1.6) to the nearest degrees is 58degrees

-7x - 2y = 14
6x + 6y = 18
Answer:
x=-4, y=7
Step-by-step explanation:
Answers : x = (15/6), y =
(1/2).
Step-by-step explanation:
Explanation: To solve this equation through elimination, you need to isolate one of the variable. You can isolate the y variable since the x variables can be subtracted and go away. Add the two equations to get rid of one variable. (6x + 6y = 18) + (-6 + 2y = -14) = (8y = 4). Now you need to solve for y. y = 4/8, y = 1/2. Now, plug the y back into one equation and solve for x. 6x + 6(1/2) = 18. 6x + 3 = 18. 6x = 15. x = 15/6. Plug the two answers back in to the equation to check your answers. 6(15/6) + 6(1/2) = 18, 15 + 3 = 18. -6(15/6) + 2(1/2) = -14, -15 + 1 = -14.

PLEASE HELP ASAP This probability distribution shows the
number of times a group of people takes
selfies before liking them.
Retakes
0
1
2.
3
4
Frequency
27
29
18
14
12
Using this distribution, find the probability that a
person will retake their selfie exactly 1 time.
p = [?]
Answer:
The probability is 0.29
Step-by-step explanation:
Firstly, we need to know the total number of retakes
That is simply the sum of the frequencies
we have this as;
27 + 29 + 18 + 14 + 12 = 100
so the probability of retaking exactly once will be the number of 1 retakes divided by total
That would be 29/100 = 0.29
Mia took 20 seconds to run 100m. Find the ratio of distance traveled to the time Emma took to run 100m.
Answer:
The ratio should be 100 : 20. If it needs to be simplified then 5:1
Step-by-step explanation:
100 m is the distance traveled and the time it took was 20 seconds. Divide both sides by 20 and you get 5:1
(If it doesn't need to be simplified then 100 : 20)
Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains
Answer:
225 milliliters
Step-by-step explanation:
Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains. how much slushy was originally in the cup?
let x = slushy originally in the cup
total slushy consumed in 17 seconds = 17 x 4.5 = 76.5 ml
x - 76.5 = 148.5
collect like terms
x = 148.5 + 76.5
x = 225 ml

Which expression is equivalent to 2(x2 – 1) + 3x(x – 4)?
(1) 5x2 – 5
(3) 5x2 – 12x – 1
(2) 5x2 - 6
(4) 5x2 – 12x – 2
The equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2
How to find equivalent expression?
The equivalent expression of the expression can be found as follows;
2(x² – 1) + 3x(x – 4)
open the brackets
2x² - 2 + 3x² - 12x
Therefore, let's combine like terms
2x² + 3x² - 12x - 2
Let's do the arithmetic for like terms
2x² + 3x² - 12x - 2
5x² - 12x - 2
Therefore, the equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2

From the graph of the regression model given, the estimated hourly rate for an individual with 5 years experience would be $11.
The graph models the relationship between hourly rate and years of experience. The point of intersection of the y and x axis on the regression line gives the pair of points.Hence, the value of y, when x = 5 on the regression line is $11.
