For a given input value a, the function f outputs a value b to satisfy the following equation.
-3a+6b=a+4b
Write a formula for f(a) in terms of a

Answers

Answer:

ok

Step-by-step explanation:

-3a + 6b = a + 4b

we move both values to the same side

6b – 4b = a + 3a

subtracting 6 from 4 gives us 4, and a 1 plus 3 gives us 4

2b = 4a

divide 4 on both sides to solve for a and to get a by itself.

1/2=a

please mark as brainlest.

Hey there!

Let's solve for a.

[tex] \fbox{−3a+6b=a+4b}[/tex]

Step 1: Add -a to both sides.

[tex] \fbox{−3a+6b+−a=a+4b+−a}[/tex]

[tex] \fbox{−4a+6b=4b}[/tex]

Step 2: Add -6b to both sides.

[tex] \fbox{−4a+6b+−6b=4b+−6b}[/tex]

[tex] \fbox{−4a=−2b}[/tex]

Step 3: Divide both sides by -4.

[tex] \fbox{−4a/−4 = −2b/−4}[/tex]

[tex] \fbox{a= 1/2b}[/tex]

[tex] \fbox{a= 1/2b}[/tex]

A balance scale is perfectly balanced with 2 cans of soda on one side and 1 can of soda and 8 ounces of sand on the other . How much does each can of soda weigh?

Answers

The balance scale is perfectly balanced when it sits perfectly

The weight of each can of soda is 8 ounces

How to determine the weight of the soda can

Represent the weight of the can with x.

On the first side, where there are 2 cans of soda.

The weight is 2x

On the other side, where there is 1 can of soda and 8 ounces of sand

The weight is x + 8

Since the balance scale is perfectly balanced, then we have the following equation

2x = x + 8

Subtract x from both sides

x = 8

Hence, the weight of each can of soda is 8 ounces

At the amusement park, the Ferris wheel is located 95 feet east and 156 feet north of the entrance. The swings are located 23 feet west and 124 feet north of the entrance. If Jalen is standing exactly three-eights the distance from the Ferris wheel to the swings, to the nearest hundredth of a foot, find the direct distance between Jalen and the entrance. (Round your answer to the nearest tenth)

Answers

Answer:

120.62 feet

Step-by-step explanation:

Let the entrance be the origin (0,0). If  the Ferris wheel is located 95 feet east and 156 feet north of the entrance, its coordinates are (95, 156). If the swings are located 23 feet west and 124 feet north of the entrance, its coordinates are (-23, 124).

We now find the distance from the swing to the Ferris wheel which for a pair of coordinates (x₁, y₁) and (x₂, y₂) is gotten from d = √[(x₂ - x₁)² + (y₂ - y₁)²] where (x₁, y₁) = (-23, 124) and (x₂, y₂) = (95, 156).

So, d = √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(95 - (-23))² + (156 - 124)²]

= √[(95 + 23))² + (156 - 124)²]

= √[(118)² + (32)²]

= √[13924 + 1024]

= √14948

= 122.26 feet

Since Jalen is standing exactly three-eights the distance from the Ferris wheel to the swings, his distance from the Ferris wheel is d' = 3d/8 = 3 × 122.26/8 = 45.85 feet

To find the coordinates (x', y') of Jalen's point from the entrance, we subtract his distance from the Ferris wheel from the coordinates of the point of the Ferris wheel. So, (x', y')  = (95 - 45.85, 156 - 45.85) = (49.15, 110.15).

So, Jalen's distance from the entrance is gotten from

d = √[(x₂ - x₁)² + (y₂ - y₁)²] where (x₁, y₁) = (0, 0) and (x₂, y₂) = (49.15, 110.15).

So, d = √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(49.15 - 0)² + (110.15 - 0)²]

= √[(49.15)² + (110.15)²]

= √[‭2,415.7225‬ + ‭12,133.0225‬]

= √‭14,548.745‬

= 120.62 feet

Which inequality represents all the solutions of -2(3x + 6) ≥ 4(x + 7)?

A. x ≥ -4

Answers

B. x < -4

-2(3x + 6) > 4(x + 7)

-6x - 12 > 4x + 28

-10x > 40

X < -4

The inequality that represents the solution of -2(3x + 6) ≥ 4(x + 7) is  x ≤ -4, the correct option is B.

What is an Inequality?

An inequality is a statement that is formed when two expressions are joined using an inequality operator.

The inequality is -2(3x + 6) ≥ 4(x + 7)

To find the solutions, the inequality has to be simplified.

Solving the inequality by using Distributive Property,

-6x -12 ≥ 4x +28

Adding (+12) on both sides of the inequality

-6x ≥ 4x +28 +12

Adding (-4x) on both the sides of the inequality

-6x + (-4x) ≥ 40

-10x ≥ 40

Dividing 10 on both the sides

-x ≥ 4

x ≤ -4

Answers

The two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).

What is the independent events?

Independent events are those events whose occurrences do not depend on the other events.

A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested.

Consider the following events:

A. The burrito is a chicken burrito.B. The burrito is a carne asada burrito. C. The customer requested black beans. D. The customer requested pinto beans.

The probability of event A is,

[tex]P(A)=\dfrac{83}{240}[/tex]

The probability of event B is,

[tex]P(B)=\dfrac{80}{240}=\dfrac{1}{3}[/tex]

The probability of event C is,

[tex]P(C)=\dfrac{45}{240}=\dfrac{3}{16}[/tex]

The probability of event D is,

[tex]P(A)=\dfrac{72}{240}=\dfrac{3}{10}[/tex]

If the probability of an event is calculated given that the other is happened, only the probability of event B and D we get such that,

[tex]P(B\cap D)=P(B).P(D)\\\dfrac{24}{240}=\dfrac{1}{3}\times \dfrac{3}{10}\\\dfrac{1}{10}=\dfrac{1}{10}[/tex]

Answers

Answer:

60

Step-by-step explanation:

all sides are equal

The value of y is 60. so the answer is D. 60°.

In a triangle, the sum of all angles is always 180 degrees.

If two angles of a triangle are 60 degrees each, the third angle can be found by subtracting the sum of the other two angles from 180 degrees.

So, the third angle would be:

60 + 60 + y = 180

y = 180° - 60° - 60°

y  = 60°

Therefore, the value of the third angle, which is represented by y in this case, is 60°.

Therefore, correct answer is D. 60°.
