Lets x and y are the 2 numbers
<span>One number is 5 more than another number: x = y + 5
</span><span>The sum of the two numbers is 43: x + y = 43
substitute </span>x = y + 5 into x + y = 43
x + y = 43
y + 5 + y = 43
2y = 38
y = 19
x = y + 5 = 19 + 5 = 24
answer
Two numbers are 19 and 24
Answer:
See below.
Step-by-step explanation:
sin2x-tanx
= 2sinx cosx - sinx/cos
= (2sinx cos^2x - sin x) / cos x
= sinx ( 2 cos^2x - 1 ) / cos x
Now sin x / cos x = tanx and 2 cos^2 x - 1 = cos2x
so this simplifies to cos2x tan x.
Answer:
The advantages & disadvantages of tables,graphs and words have been explained below.
Step-by-step explanation:
The 3 major representation for finding patterns and making predictions are;
1.Tables
2. Graphs
3. Words
This means we want to find the advantages and disadvantages of using tables, graphs and words for finding patterns and making predictions.
1) Tables: Advantage is that we will be able to directly see the exact effect of the input variable on the output. While the disadvantage is that it's very difficult to see patterns.
2) Graphs: Advantage is that we can easily see the pattern of the representation. However the disadvantage is that we can't see the exact values arising from the effect of the input variable on the output.
3) Words: The advantage is that we can describe the data values in clear terms. However, the disadvantage is that we can't get exact values from just the words.
1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.
1. m{t}°=64 m{I}°=58
2. This one is easy because algebra is the key.
Add like-terms.
x=5
The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
