Y=3x+4.....eq.(i) x+4y=-10....(eq.ii) putting value of y in eq.(ii),we get, x+4(3x+4)=-10 or x+12x+16=-10 or,13x=-10+16 or,13x=6 ●#x=6÷13 putting value if x in eq.(i),we get y=3(6÷13)+4 or,y=18÷13+4 or,y=(18+52)÷13 ●#y=70÷13

What is the circumference of circle p ? Express in terms of pie
SVETLANKA909090 [29]
The circumference of a circle is calculated using the following equation:

C= \pi d

Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).

We know that the diameter of the circle given (also known as AB) is equal to 20 cm.

We can then plug this into the equation and solve for the circumference:

C= \pi (20)

Since the question asks for the answer to be in terms of \pi, this is as far as we need to go. So the circumference of the circle is: 20 \pi or D.

What is the inverse of y=pi/2+sin x​
Alekssandra [29.7K]

Answer:

f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})

Step-by-step explanation:

The given function is

y=\frac{\pi}{2}+\sin x

To find the inverse of this function, we interchange x and y.

x=\frac{\pi}{2}+\sin y

we now solve for y.

x-\frac{\pi}{2}=\sin y

Take the sine inverse of both sides to obtain;

\sin ^{-1}(x-\frac{\pi}{2})=y

Hence the inverse of the given function is;

f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})

where \frac{\pi}{2}-1\le x\le \frac{\pi}{2}+1

HELP ME PLEASE PLEASE IM BEGGING
suter [353]

Answer:

FALSE, (2, 9) is not a solution to the set of inequalities given.

Step-by-step explanation:

Simply replace x by 2 and y by 9 in the inequalities and see if the inequality is true or not:

irst inequality:

y\geq 4x\\9\geq 4\,(2)\\9\geq 8

so thi inequality is verified as true since 9 is larger or equal than 8

Now the second inequality:

y

This is FALSE since 9 is larger than 4 (not smaller)

Therefore the answer to the question is FALSE, (2, 9) is not a solution to the set of inequalities given.

Víctor claims that when 1/6 is divided by a fraction the result will always be greater than 1/6 find an example of a fraction th
Naddik [55]

Answer:

Step-by-step explanation:

Choose a random fraction less than 1. I will choose 1/4.

1/6 ÷ 1/4 = 1/6 × 4/1 = 4/6 = 2/3

2/3 > 1/6 so this example supports his claim.

Now chose a fraction greater than 1. I will choose 4/3

1/6 ÷ 4/3 = 1/6 * 3/4 = 3/24

3/24 < 1/6 so this contradicts his claim
