Answer:
a = 9 / 7
step by step explanation:
9 / - a + 15 = 8
Determined the defined range
9 / ( - a ) + 15 = 8 , a ≠ 0
subtract 15 from each side
9 / - a + 15 - 15 = 8 - 15
calculate the difference
9 / - a = - 7
multiply both side of equation by - a
9 / - a × - a = - 7 × - a
9 = 7 a
divide each side by of equation by -7
9 / 7 = 7 a / 7
9 / 7 = a
swap the side of equation . ( optional )
a = 9 / 7

Answer:
x=10
Step-by-step explanation:
To solve for x, you need to draw an imaginary line connecting the right end of side x to the left side with length 15. This forms a triangle with side lengths 6 and 8, and hypotenuse x. Using the Pythagorean Theorem to solve for x, we get 6^2 + 8^2 = x^2, 36 + 64 = 100, [tex]\sqrt{100}[/tex] = 10.
Answer:
It's 10
Step-by-step explanation:
C^2=A^2+B^2blank
C=√(A^2+B^2)
If c is x and a and b are the side lengths the we can use Pythagoras's theorem to calculate the length of the line. A=6 B=8 and in the end when you calculate all that doohickey stuff you get x=10

What is the slope of the line that contains the points (14,-2) and (3,-2)
Answers
Answer:
0
Step-by-step explanation:
We can use the slope formula since we have two points
m = ( y2-y1)/(x2-x1)
= ( -2- -2)/(3-14)
= ( -2+2)/(3-14)
= 0/-11
= 0
Answer:
0 is the slope of the line that contains the points (14,-2) and (3,-2)
Step-by-step explanation:
We have two points which are ( 14 , -2) and ( 3, -2).To find , the slope is the slope of the line that contains the points (14 , -2)and (3, -2)
we using slope formula which is
m = ( y ² - y ¹ ) / ( x ² - x ¹)Where,
m , is the slope
( y ² - y ¹ ) = ( 14 , - 2)
( x ² - x ¹) = (3, -2 )
Substitute the values into the formula
m = (( -2 )- ( -2 ) ) / (3 - 14 )
m= ( -2 + 2 ) / ( 11)
m = 0 / 11
m = 0
Therefore , 0 is the slope of the line that contains the points (14,-2) and (3,-2)

Answers
Answer:
3(2x + 1)(3x - 5)
Step-by-step explanation:
Given
18x² - 21x - 15 ← factor out 3 from each term
= 3(6x² - 7x - 5 ) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 6 × - 5 = - 30 and sum = - 7
The factors are + 3 and - 10
Use these factors to split the x- term
6x² + 3x - 10x - 5 ( factor the first/second and third/fourth terms )
3x(2x + 1) - 5(2x + 1) ← factor out (2x + 1) from each term
(2x + 1)(3x - 5)
Then
18x² - 21x - 15 = 3(2x + 1)(3x - 5)

You start driving west for 9 miles, turn right, and drive north for another 6 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
Answers
Answer:
10.8 mi
Step-by-step explanation:
Picture a right triangle with legs 9 mi and 6 mi. Applying the Pythagorean Theorem (d² = a² + b²), we get:
(9 mi)² + (6 mi)² = 117 mi²
This is the square of the hypotenuse (the desired distance).
Taking the square root of both sides, we get d = √(117 mi) ≈ 10.8 mi = d
The desired straight line distance traveled is 10.8 mi

The mean amount of sleep needed for adults is 503 minutes per night. If the standard deviation for adult sleepers is [s]. What is the Z score associated with sleeping 503 minutes per night?
Answers
Answer:
Z score associated with sleeping 503 minutes = 0 minutes
Step-by-step explanation:
Given values of sleep per night for adults:
Mean value X = 503
Standard deviation σ = s
FInd:
Z score associated with sleeping 503 minutes
Computation:
⇒ P[X = 503]
⇒ P[(x - X) / σ] = [503 - 503] / s
⇒ Z score value = [0] / s
⇒ Z score value = 0
Z score associated with sleeping 503 minutes = 0 minutes

Write an equation of a line that passes through the points (1, 7) and (5, 19) . Give the final form in slope intercept form. (Please no fake answers or Links)
Answers
Answer:
y = 3x + 4
Step-by-step explanation:
slope = (y2 -y1)/(x2 - x1)
y2 = 19
y1 = 7
x2 = 5
x1 = 1
Slope = (19 - 7)/(5 - 1)
slope = 12 / 4
slope = 3
So far what you have is
y = 3x + b To solve for b, use either of the two points.
x = 1
y = 7
7 = 3(1) + b
7 = 3 + b
b = 4
The final equation is
y = 3x + 4
We should check that with the other point
x = 5 Find y
y = 3(5) + 4
y = 15 + 4
y = 19 Ans it checks.
