Answer:

4 cm (A)

Step-by-step explanation:

triangle BAC is just a larger version of triangle EAD. given that ED is 5cm, and BC is 10cm, triangle BAC must be twice the size of EAD. since the ratio of AD to ED is 4:5, and BC is twice the size, all we need to do is multiply both sides by 2 to find length AC. 4*2 = 8. now we can subtract length AD from AC to get CD. 8 - 4 = 4.

sorry if what i wrote is a little confusing

Question 4
Svetach [21]

A) Composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks is f[s(w)] = 50w + 25.

B) The unit of measurement for the composite function is flowers.

C) Number of the flowers for 30 weeks will be 1525.

<h3>What is a composite function?</h3>

A function is said to be a composite function when a function is written in another function. The composite function that represents the number of flowers is f[s(w)] = 50w + 25. and the number of flowers for 30 weeks is 1525.

Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks.

From the given data we will find the function for the number of flowers with time.

f(s) = 2s + 25

We have  s(w) = 25w

f[(s(w)]=2s(w) + 25

f[(s(w)] = 2 x ( 25w ) +25

f[s(w)] = 50w + 25.

Part B: What are the units of measurement for the composite function in Part A

The expression f[s(w)] = 50w + 25 will give the number of the flowers blooming over a number of the weeks so the unit of measurement will be flowers.

Part C: Evaluate the composite function in Part A for 30 weeks.

The expression f[s(w)] = 50w + 25 will be used to find the number of flowers blooming in 30 weeks put the value w = 30 to get the number of the flowers.

f[s(w)] = 50w + 25.

f[s(w)] = (50 x 30) + 25.

f[s(w)] = 1525 flowers.

Therefore the composite function is f[s(w)] = 50w + 25. unit will be flowers and the number of flowers in 30 weeks will be 1525.

What is the solution of this system of linear equations?<br><br> 3y = x + 6<br><br> y – x = 3
Naya [18.7K]
<span>3y = x + 6
y – x = 3 ----------->  x=y - 3 (substitute in 1st equation)

3y = y - 3 +6
3y - y = 3
2y = 3
y = 2/3

x= y - 3 = 2/3 -3 = 2/3 - 9/3 =  - 7/3

</span>x= - 7/3, y = 2/3<span>
