Answer:
y=15-x
Step-by-step explanation:
3y=45-3x
y=15-x
If you want to solve for y, you need another one equation
1−x−−−−√≈−12x+1
0.9−−−√=1−0.1−−−−−−√≈−12(0.1)+1
To simplify:
−1/2⋅1/100+1=−1/2⋅1/100+200/200=200−1/200=199/200 or =.995
So yes for sqrt (.99), that is a good approximation.
To write linear approximations:
Our curve should be y=f(x) and substitute x=a for the numbers m
Our formula for the
linear equation is y=mx+b
So subtsitute
y′=f′(x)
y=f′(a)x+b
Then find the y-intercept, which is b.
Given: (a, f(a))=
point of the line
Then substitute, that would be
f(a)=f′(a)⋅a+b
f(a)−f′(a)⋅a=b
So the tangent line to y=f(x) at x=a
Or the equation we will use for linear approximations is:
y=f′(a)x+f(a)−f′(a)⋅a
y=f′(a)⋅(x−a)+f(a)
Answer:
<u>1. 4/13 = 20/65
</u>
<u>2. 4/20 = 13/65 </u>
<u>3. 5/10 = 23/46</u>
<u>4. 5/10 = 32/64
</u>
<u>5. 5/23 = 10/46
</u>
<u>6. 5/32 = 10/64</u>
Step-by-step explanation:
We can make the following six equivalent ratios using the digits from 0 to 6 only once:
1. 4/13 = 20/65 (We multiply 4 and 13 by 5 to get the second equivalent ratio)
2. 4/20 = 13/65 (We divide the first ratio by 4 and the second by 13 and we get 1/5 on both ratios)
3. 5/10 = 23/46 (We divide the first ratio by 5 and the second by 23 and we get 1/2 on both ratios)
4. 5/10 = 32/64
(We divide the first ratio by 5 and the second by 32 and we get 1/2 on both ratios)
5. 5/23 = 10/46
(We multiply 5 and 23 by 2 to get the second equivalent ratio)
6. 5/32 = 10/64 (We multiply 5 and 32 by 2 to get the second equivalent ratio)

Answer:
x = 38
Step-by-step explanation:
Exterior Angle Theorem
x + 99 = 137
subtract 99 from both sides and...
x = 38!
