So 8x-7y=-7
-16+12x=14
you can simplify the sceon equation
-8+6x=7
add 8 to both sides
6x=15
divide by 6
x=15/6
subssitute
8(15/6)-7y=-7
120/6-7y=-7
20-7y=-7
subtract 20
-7y=-27
divide by -7
y=27/7

x=15/6
y=27/7

ExtremeBDS [4]
Given the function h(x)=\arcsin(x)

Part a:

Considering the input of h

i.) A valid unit of measure for the input quantity is Seconds

ii.) The possible input values, i.e. the domain of h are -1 ≤ x ≤ 1



Part B:

i.) A valid unit of measure for the output quantity is the Radians.

ii.) The possible output values, i.e. the range of h is 0 ≤ h ≤ 2π



Part C:

i.) \arcsin\left(\sin\frac{\pi}{3}\right)=\frac{\pi}{3}

ii.) \arcsin\left(\sin\frac{2\pi}{3}\right)=\frac{2\pi}{3}

iii.) \arcsin\left(\sin\frac{7\pi}{6}\right)=\frac{7\pi}{6}

iv.) \arcsin\left(\sin\frac{7\pi}{4}\right)=\frac{7\pi}{4}

One number is 3 less than twice another. If their sum is 39, find the numbers.
stiv31 [10]
Answer:
y = 2x- 3 and x + y = 39

Explanation:
Twice of a number indicates the 2x in the equation. It’s also 2 less than the 2x. That’s where the 2x-3 part comes from. The question indirectly states to find the sum of x and y. That sum should equal 39We can now plug in the information and get the second part of the equation, x+ y = 39
