i hope this helps :)

The value of the inequality will be : y ≥ -10 .

Given ,

y-5 ≥ -15

Here,

y-5 ≥ -15

To solve the given inequality,

Take -5 from LHS to RHS of inequality,

y ≥ -15 + 5
y≥ -10

Thus the value of y will be equal to or greater than -10 .

Answer:

f(x)=-2x^2+32x-114

Step-by-step explanation:

Answer:

f(x) = -2x^2 + 142

Step-by-step explanation:

f(x) = -2(x - 8)^2 + 14

f(x) = -2(x)^2 - (-2)(-8)^2 + 14

f(x) = -2x^2 - (-2)(64) + 14

f(x) = -2x^2 - (-128) + 14

f(x) = -2x^2 + 128 + 14

f(x) = -2x^2 + 142

Answer:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

Step-by-step explanation:

The standard form for a sinusoidal function is given by:

y = Asin[B(x - C)] + D

Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation

Given:

A = 2, D = -5 (down), C = -3 (left).

8 = 2π/B; B = π/4

Therefore:

[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

The probability of randomly drawing a yellow marble is 5/16.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that  bag contains 13 blue marbles, 9 red marbles, and 10 yellow marbles

There are a total of 13 + 9 + 10 = 32 marbles in the bag, out of which 10 are yellow.

The probability of randomly drawing a yellow marble can be found by dividing the number of yellow marbles by the total number of marbles:

P(Yellow marble) = Number of yellow marbles / Total number of marbles

= 10 / 32

Simplifying this fraction, we get:

P(Yellow marble) = 5 / 16

Therefore, the probability of randomly drawing a yellow marble is 5/16.

Answer:

It would take Lena 9 hours.

Step-by-step explanation:

Looking at the problem I can do 696/12 to get the number of miles per hour she is traveling which is 58. With this number, I can take 522/58 to get 9 hours.

Answer:

Step-by-step explanation:

Remark

The best way to do this is to set up a proportion. It can be done by using d = r * t twice, but a more direct way is to use the proportion.

Formula

distance1 / time1 = distance2 / time2

Givens

distance1 = 696 miles

time1 = 12 hours

distance2 = 522 miles

time2 = x

Solution

696/12 = 522/x       Cross multiply

696 * x = 522* 12    Combine the right

696 * x = 6264        Divide by 696

x = 6264/696

x = 9 miles

Answer:

4.6 miles for 5 days.
