To solve, you will need to find the y intercept which in this case is on the graph. The find the slope's between the two points and calculate the average slope by adding the two then dividing. Hope that helps!
Answer:
x=12
Step-by-step explanation:
(8x-20)+(8x+8)=180
16x-12=180
16x=180+12
16x=192
x=12
<h3>
Answer: 49/100</h3>
=========================================================
Explanation:
There are 7 dimes and 3 pennies, leading to 7+3 = 10 coins total.
The probability of not picking a penny is 7/10. If the first coin is put back, then the probability doesn't change for the second selection.
The probability of getting two dimes is (7/10)*(7/10) = 49/100 when the first coin is replaced.
If the first coin is not replaced, then the answer would be (7/10)*(6/9) = 42/90 = 7/15
Answer:
Step-by-step explanation:
For women, the initial number is 6, constant rate of change is w, number of years is x.
<u>Find the rate of change and work out the required formula:</u>
- 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5
<u>Formula:</u>
<u>Similarly for men, we get:</u>
- 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5
<u>Formula:</u>
Using translation concepts, it is found that this transformation can be described as a reflection across the x-axis.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, considering the vertices of quadrilateral 1 and quadrilateral 2, the transformation from quadrilateral 1 to quadrilateral 2 has the following format:
(x,y) -> (x, -y).
Which means that it can be described as a reflection across the x-axis.
