Answer:
(-78/29, -619/29)
Step-by-step explanation:
Since both equations are equal to y we can set them equal to each other
15x+19 = 1/2x - 20
Subtract 1/2x from each side
15x -1/2x +19 = -20
Subtract 19 from each side
14 1/2 x +19-19 = -20-19
Changing to an improper fraction
29/2 x = -38
Multiply each side by 2/29
x = 2/29 * -38
x = -78/29
Now find y
y = 1/2x - 20
y = 1/2 (-78/29) -20
y = -39/29 - 20
Get a common denominator
=-39/20 - 580/29
= -619/29
-39/29 -580/29
Answer:
D) radical 26
Step-by-step explanation:
So this is a question where you need to find the hypotenuse of a triangle
the sides are 1 and 5
you can use Pythagoras (a^2+b^2=c^2)
substitute the values in
1^2+5^2=c^2
simplify the exponents
1+25=c^2
add them together
26=c^2
take the square root of 26
the answer is radical 26
(1) C and (2) D
(1)
distribute the left side of the equation
2h - 16 - h = h - 16 ( simplify left side )
h - 16 = h - 16
Since both sides are equal, any value of h will make the equation true.
Hence there are infinitely many solutions to the equation → C
(2)
3 + 6z = 13 + 6z ( subtract 6z from both sides )
3 = 13 ← not possible
Hence there are no solutions to the equation → D

Answer:
False
Step-by-step explanation:
False. The period of y = tan x is π, whereas that of y = cos x is 2π.
