We will use substitution to solve the system. Step 1 is partially complete.

[tex]y = -2x - 9\\6x - 5y = -19\\\\6x - 5(-2x - 9) = -19\\\\6x + 10x + 45 = -19\\\\16x + 45 = -19\\\\16x = -64\\\\x = -4[/tex]

We will now use what we got for x to solve for y in one of the original equations.

[tex]6(-4) - 5y = -19\\\\-24 - 5y = -19\\\\-5y = 5\\\\y = -1[/tex]

The solution is (-4, -1).

I rounded the totals.

Answer:

After 25 years both the accounts will have the same balance.

Step-by-step explanation:

Let t years, both the account will have the same balance.

As account A has a beginning balance of $500 and grows by $25 per year.

So, the total balance of account A after t years = 500+25t

Similarly, account B has a beginning balance of $750 and grows by $15 per year.

So, the total balance of account A after t years = 750+15t

As both the accounts has the same balance, so

500+25t= 750+15t

25t-15t=750-500

10t=250

t=250/10

t=25 years

Hence, after 25 years both the accounts will have the same balance.

Answer:

y < 12x

....................

The shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. An inequality is used to compare two or more mathematical expressions.

We have the following inequality -

y < -2x + 10

We can write -

y < -2x + 10

Refer to the graph of the inequality attached. The shaded region represents the viable solution ordered pairs.

Therefore, the shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.

Answer:

72 sec im srry if its wrong i cant see it good

Step-by-step explanation:

Answer:

Step-by-step explanation:

The points are in the format (x , y) so given x which is the first figure, you can find y by following the formula.

Y in the point needs to satisfy the criterion of X + 3.

Point A

x = -1

y = x + 3

= -1 + 3

y = 2

Point A satisfies the equation as y from the equation is y in the point given.

Point B

x = -1

y = x + 3

= -1 + 3

y = 2

Point B does not satisfy the equation and so is not on the line.

Point C

x = 2

y = 2 + 3

y = 5

Point C satisfies the equation as y from the equation is y in the point given.

Point D

x = -3

y = -3 + 3

y = 0

Point D satisfies the equation as y from the equation is y in the point given.

An equation that models the total cost (C), in dollars, of a taxi cab ride, where m is the number of miles driven is,

C = 0.75 m + 8

The correct option is C.

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

Given:

A taxi cab company charges $8.00 per ride plus $0.75 for each mile driven.

An equation that models the total cost (C), in dollars, of a taxi cab ride, where m is the number of miles driven is,

C = 0.75m + 8

Therefore, C = 0.75m + 8.

Answer:

Step-by-step explanation:

The correct answer is D because 7 plus 3 is 10, not 11

its kinda hard but when I closed your screen I didn't see any questionsir

I see a fraction. Don't you. Here it is 17/20. Now, let's divide 17 by 20 to get a decimal number, which is 0.85. Next, we multiply 0.85 by 100 to get the percent because that is what the question desires for us to express our answer. As a result, we get 85%, and Antonio made 85% of his free throws. By the way, I hope my response helps you.  

Step-by-step explanation:

1 way is to do 17/ 20 using long division...

    0. 85

20⟌1700    ( I tried my best)

   - 160

      100

So the answer would be 85%

Another way to do it is by bringing the denominator to 100

Since 20 is 1/5 of 100, you would have to multiply the numerator and denominator by 5

17/ 20 = 17*5/ 20*5 = 85/ 100

And you get 85%

Answer:

y=75

Step-by-step explanation:

Alright first off you want to be able to find the ratio to this to be able to find that Y you are looking for.

If you simplify y=45 and x=3 both by 3 you will get:

y=15 and x=1

now, lets turn that X to a 5 just like the other x which equals 5 as well...

but here's the catch when you times our X by 5 to equal 5 we are also going to times our Y by 5 to and do you know what 15 times 5 is it's 75.

now that we know that let's type that out to make it clear:

x=5 and y=75

you see the pattern now ;)

Answer:

5/7

Step-by-step explanation:

You are adding both fractions together to determine the total of the floor they both cleaned in all.

so 2/7 + 3/7 =    

To add fractions, you need both denominators to be the same. In this case, they are already the same so you don't need to adjust the fraction before adding them.

Now all you need to do is to add the numerators together so

2 + 3 = 5

So you put the numerator total over the common denominator.

* You do not add the denominators, only the numerators.
