Answers
Answer:
x= 8
Step-by-step explanation:
1. Expand.
3x-9=-2x+31
2. Add 9 to both sides.
3x=-2x+31+9
3. Simplify -2x+31+9 to -2x+40.
3x=-2x+40
4. Add 2x to both sides.
3x+2x=40
5. Simplify 3x+2x+5x.
5x=40
6. Divide both sides by 5.
x = 40/5

{(2,1,1),(5,2.2),(12,3.3),(15,4.4)}
{(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}
Answers
Given:
The set of ordered pairs is
{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}
To find:
Which relation has the same domain as the given relation?
Solution:
We know that, domain is the set of input values or x-values.
For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is
Domain={0.5, 1.5, 4.0, 6.5}
Similarly,
For {(1,5),(2,2),(-3,15),(-8,12)},
Domain = {1, 2, -3,-8}
For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},
Domain={0.5, 1.5, 4.0, 6.5}
For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},
Domain = {2, 5, 12, 15}
For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)},
Domain = {-1, -3, -6, -10}
So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.
Therefore, the correct option is B.

Select the solution(s) of log2x=1−log(x+4).
Answers
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1

In ΔJKL, k = 430 cm, l = 590 cm and ∠J=117°. Find the length of j, to the nearest centimeter.
Answers
Answer:
874
Step-by-step explanation:
The length of j from the given triangle JKL is 550 cm.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔJKL, k = 430 cm, l = 590 cm and ∠J=117°.
Using cosine rule
j²=k²+l²-2kl.cosJ
j²=430²+590²-2×430×590·cos117°
j²=184900+348100-507400×0.4539
j²=533000-230308.86
j²=302691.14
j=√302691.14
j=550 cm
Therefore, the length of j from the given triangle JKL is 550 cm.

Gwendolyn placed a 10-foot ladder against the side of her house so that the base of the ladder was 3 feet from the base of the house, as shown in the diagram below. Which measurement in feet is closest to d, the distance from the top of the ladder to the ground?
Answers
Answer 9.5
you do the pyragtaham theory thing its A(squared) + B (squared) = C squared
you put the 3 at the A and you put the 10 at the C you sqaure them all up and then subtrct 9 from 100 and you get 91 and then you square root 91 and you get 9.5
The distance from the top of the ladder to the ground is 9.54 ft.
What is a right triangle?"It is a triangle whose one of the angle is 90°"
What is hypotenuse?"The longest side of the right triangle is called as hypotenuse."
What is Pythagoras theorem?"For a right triangle,
c² = a ² + b²,
where c = hypotenuse and a, b are other two sides of right triangle."
For given example,
Gwendolyn placed a ladder against the side of her house.
This means, it makes right triangle with ladder hypotenuse and base of the triangle is the distance between base of the ladder and the base of the house.
Let 'a' be the hypotenuse of triangle, 'b' be the base and 'd' be the distance from the top of the ladder to the ground
⇒ a = 3 ft. and b = 10 ft.
Using Pythagoras theorem,
⇒ b² = a² + d²
⇒ 10² = 3² + d²
⇒ 100 = 9 + d²
⇒ d² = 91
⇒ d = 9.54 ft.
Therefore, the distance from the top of the ladder to the ground is 9.54 ft.
