Proportions In Triangles. Solve For X

Answers

Answer 1
x = 4



x / 3 = x + 4 / x + 2

Cross multiply
x * x + 2 = 3 * x + 4

Distribute
x^2 + 2x = 3x + 12

Set equal to zero
x^2 - x - 12 = 0

Factor
(x - 4)(x +3) = 0

Solve
x = 4 or x = -3

Length can’t be negative so x = 4

Check:
x / 3 = x + 4 / x + 2
4 / 3 = 4 + 4 / 4 + 2
4 / 3 = 8 / 6
4 / 3 = 4 / 3 :)

PLSSS HELP! what is the slope-intercept equation of the line???

Answers

Answer:

y = 2x + 3

Step-by-step explanation:

( 0, 3) and (-1, 1)

m= (y2 -y1)/ (x2 - x1)

m= (1 - 3)/( -1 - 0)

m = (-2)/(-1)

m = 2

y - y1 = m (x - x1)

y - 3 = 2(x -0)

y - 3 = 2x + 0

y = 2x + 3

Step-by-step explanation:

hope this helps

The required circumference of the given circle is 25.12 cm as shown figure.

What is the Circumference of a circle?

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have been given data as follows:

The radius of the circle (r) = 4 cm

Circumference of the circle = 2πr

Substitute the values in the above formula and we get

Circumference of the circle = 2π(4)

Circumference of the circle = 3.14(8) = 25.12 cm

The required circumference of the given circle is 25.12 cm.

what is the domain of the function, f(x)?

Answers

Answer:

B. 3≤x≤ 6

Step-by-step explanation:

When a question asks for the domain of a function, it is asking for all possible x-values. Look at the graph of the function- there are no points on the graph where x=1, so we know that C and D are definitely wrong since they include 1.  The two that are left look very similar, but A means "3 is greater than or equal to x, x is greater than or equal to 6." This has to be wrong because it says that 3 is greater than 6, which is obviously incorrect. The only answer left is B, which is correct because it includes all possible x-values.

lmk if this is incorrect or hard to understand, hope this helps!!!

Mason used 1/6 of a liter of milk to make 1/8 of a jug of tea. How much milk in liters is required to fill the jug

Answers

Answer:

1.33 liters of milk are required to fill the jug.

Step-by-step explanation:

With the information provided, you can use a rule of three to find the amount of milk required to fill 1 jug of tea given that Mason used 1/6 of a liter of milk to make 1/8 of a jug of tea:

1/6 f a liter of milk → 1/8 of a jug of tea

           x                ←  1 jug of tea

x=(1/6*1)/1/8

x=(1/6)/(1/8)

x=(1*8)/(6*1)

x=8/6

x=4/3=1.33

According to this, the answer is that 1.33 liters of milk are required to fill the jug.
