Given Below. [ done below, side changing which changed sign + to - and - to + ]Step-by-step explanation:
6. x + 21 = 56
→ x = 56 – 21
→ x = 35
7. n – 13 = 8
→ n = 8 + 13
→ n = 21
8. w – 7 =41
→ w = 41 + 7
→ w = 48
9. b + 22 = 89
→ b = 89 – 22
→ b = 67
10. z – 53 = 26
→ z = 26 + 53
→ z = 79

Braden is admiring a statue in Springfield Park. The statue is 3.4 meters taller than he is, and Braden is standing 8 meters away. How far is it from the top of the statue to Braden's head? If necessary, round to the nearest tenth. meters
Answer:
8.69 m
Step-by-step explanation:
We have to use the Pythagorean theorem here
Statue is 3.4 tall, that's one leg of the right traingle
Braden is 8 meters away, that's the longer leg of the right triangle
the hypotenuse would be the distance between Braden's head and the top of the statue (let's assume it is X )
x^2 = 3.4^2 + 8^2 = 11.56 + 64 = 75.56
x = 8.69

There are about 30.5 centimeters in a foot. There are 3 feet in a yard. Choose one answer
Answer:
30feet= 91.5 centimeters
The total of cm in the 1 yard based upon 30.5 centimeters in a foot will be 91.5 centimeters.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
In another word, multiplication is nothing but changing one value by-product of another value
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Given that
1 feet = 30.5 centimeters
Given that
1 yard = 3 feet
Hence 1 yard = 3 × 30.5 centimeter.
1 yard = 91.5 centimeters hence in 1 yard there will be 91.5 centimeters

Answer:
[tex]x=3c\sqrt{a} -b^2[/tex]
Step-by-step explanation:
[tex]\sqrt{a} =\dfrac{x+b^2}{3c}[/tex]
Multiply both sides by 3c:
[tex]\implies \sqrt{a} \cdot 3c=\dfrac{(x+b^2) \cdot 3c}{3c}[/tex]
[tex]\implies 3c\sqrt{a} =x+b^2[/tex]
Subtract [tex]b^2[/tex] from both sides:
[tex]\implies 3c\sqrt{a} -b^2=x+b^2-b^2[/tex]
[tex]\implies 3c\sqrt{a}-b^2=x[/tex]
Switch sides:
[tex]\implies x=3c\sqrt{a} -b^2[/tex]
which of the following is a linear function? (89 POINTS)HURRY PLSSSSS
A linear function is a straight line formed on a coordinate plane.
To classify an equation as a linear function:
It must not have any exponent in the equation. If there is a fraction, the denominator of that fraction must not multiply by x.If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.
Option A - y = x³ + 1:
This equation has an exponent in the variable x. Hence, this is a non-linear function.Option B - 5x/6 = y - 4:
This equation has no exponents in the equation. Hence, this is a linear function and also our answer.Option C - y = 8x²
This equation has an exponent in the term 8x². Hence, this is a non-linear function.Option D - y = 1/5x
The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.Hence, Option B is correct.

A polling company is trying to estimate the percentage of adults that consider themselves happy. A confidence interval based on a sample size of 360 has a larger than desired margin of error. The company wants to conduct another poll and obtain another confidence interval of the same level but reduce the error to one-third the size of the original sample. How many adults should they now interview
Reducing the sample size to one-third, increases the error by √3.
Margin of ErrorThe margin of error is given by:
[tex]E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{n} } \\\\where\ z_\frac{\alpha}{2} \ is \ the \ confidence\ level\ z\ score, \sigma\ is \ mean\ and\ n\ is\ sample\ size.\\\\n=360, hence:\\\\E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{360} } \\\\E=0.0527(z_\frac{\alpha}{2} *\sigma)\\\\For\ n = 1/3 * 360=120:\\\\\\E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{120} } \\\\E=0.09122(z_\frac{\alpha}{2} *\sigma)[/tex]

Output y 4, 1, -2, -5, -8
y = -2 x
y = x – 6
y = -3 x - 2
y = -2 x – 2
Answer:
y = - 3x - 2
Step-by-step explanation:
The function is linear and can be expressed in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table
m = [tex]\frac{1-4}{-1-(-2)}[/tex] = [tex]\frac{-3}{-1+2}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , then
y = - 3x + c
To find c substitute any ordered pair into the equation
using (0, - 2 ) , then
- 2 = - 3(0) + c = 0 + c ⇒ c = - 2
y = - 3x - 2 ← function rule
Answer:
y = - 3x - 2
