Answer:

35 and 55

Step-by-step explanation:

x+(2×-15)=90

3x-15=90

3x=105

x=35

other angle is 35×2-15=55

Need help and will be giving Brainliest

Katena32 [7]

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

An hour befor show time,only 155 people are seated for rockfest.According to ticket sales 95% of the people have yet to arrive

Ludmilka [50]

Question:

An hour before show time, only 155 people are seated for rockfest. According to the ticket sales, 95% of the people have yet to arrive. How many tickets were sold?

Answer:

3100 tickets

Step-by-step explanation:

Given

$p = 95\%$ --- Yet to arrive

$Seated = 155$

Required

Determine the total number of people

If 95% are yet to arrive, then 5% have arrived (i.e. 100% - 95%)

So, the total number of people is calculated as:

$5\% * x = 155$

Where x represents the total number of tickets

Make x the subject

$x = \frac{155}{5\%}$

$x = \frac{155}{0.05}$

$x = 3100$
