Part A: Solve −np − 90 < 30 for n. Show your work. Part B: Solve 5m − 3h = 45 for h. Show your work.

Answers

A.well to start you have to do  np + 90 >- 30
np > - 20
n > - 120/p

and for b. 
5m - 45 = 3h
so h = 5m/3 - 15

find slope and y-int explanation

Answers

To find the answer to the slope and y-intercept of this equation, you first must put it in slope-intercept form. After you do that, you get the equation y=3/4x - 1. Therefore, the slope is 3/4, and the y-intercept is -1.

F(x)=4x^2+7x+18 find f (-9)

Answers

Answer: f(-9)= 243

Step-by-step explanation:

f(x) = 4x²+7x -18

f(-9) = 4(-9)²+7(-9)-18

= 4(81) -63-18

= 324- 81

= 243

There are 45 red tiles,25 blue tiles and 30 green tiles in a bag.Suppose you plan to conduct this experiment 60 times.
Draw a tile from the bag without looking.
Record the color of the tile
Replace the tile
How many tiles of each color do you expect to get?

Answers

This is a question of probability.
Probability of picking any color= number of tiles with that color/total number of tiles
Total=45+25+30=100
P(red tile)=(45/100)x60=0.45x60=27
P(blue tile)=(25/100)x60=0.25x60=15
P(green tiles)=(30/100)x60=0.3x60=18

Solve of system of equation.
9x + 2y = -38
9x+10y=26.

Answers

Final answer:

The system of equations can be solved using the method of elimination. The solution is x = -6 and y = 8.

Explanation:

To solve this system of equations, we can use the method of elimination. First, we'll multiply the first equation by 10 and the second equation by 2 to make the coefficients of x the same. This gives us:




  2.  
  3. 90x + 20y = -380

  5.  
  6. 18x + 20y = 52



Now, we can subtract the second equation from the first to eliminate y:



72x = -432



Dividing both sides by 72, we find x = -6.



Substituting this value of x into one of the original equations, we can solve for y:



9(-6) + 2y = -38



Simplifying, we get -54 + 2y = -38



Adding 54 to both sides, we have 2y = 16



Dividing both sides by 2, we find y = 8.
