Answer: A

Step-by-step explanation:

The solution to the graph of inequality given above is the shaded portion or the shaded part of the graph.

Since the point ( -3, -3) and ( 3, -1 ) are on the point line, and the line is a broken line, the inequality means greater than. That means that solution must be greater than those point. They are therefore not part of the solution.

Point ( 5, -5), where x = 5 and y = -5, according to the graph, the shaded portion does not cover y at -5.

Option C is therefore the correct answer which is within the shaded portion. (1, 5)

Step-by-step explanation:

You are finding the whole

0.7 × 20 = 14

70% of 20 = 7/10 x 20 = 7/10 x 20/1 = 140/10

140/10

140/10 = 14/1

The minimum number of questions he need to do are 14

I'm not sure if you are finding the part or the whole

let me know if im wrong

A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria,

DIA [1.3K]

Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000

Growth rate = r = 150% = 1.50

The equation model for this situation is:

$A= A_{o}(1+r)^{t}$

Using the values in above equation, we can write:

$45000000=100(1+1.5)^{t} \\ \\ 
450000=(2.5)^{t} \\ \\ 
log(450000)=log((2.5)^{t}) \\ \\ 
log(450000)=t*log(2.5) \\ \\ 
t= \frac{log(450000)}{log(2.5)} \\ \\ 
t=14.21$

This means, the person will fall sick after about 14 hours.

4x + 8y=20<br> 3x+6y=15<br> solve this system of equations

laila [671]

4x=20-8y

x=5-2y now use this value of x in the second equation...

3(5-2y)+6y=15

15-6y+6y=15

15=15 This is true for any y or x value.

So there are infinitely many solutions as the two equations describe the same line.

The Millers receive a dinner bill for $122.75. The sales tax rate is 8%. They want to leave an 18% tip on the total bill after t

Aleks04 [339]

Answer:

they will start with $122.75 dollars to be paid and add on 8% of $122.75 which is $9.82.

the next step would be to add together 122.75+9.82 and you get $132.57

the last step woukd be to find what 18% of 132.57 is and that would be $23.86

add 132.57+23.86=$156.43

$156.43 is your answer
