Answer 1

Answer:

1) x=6, y=-6 which is (6,-6) as an ordered pair

3) x=10, y=-1 which is (10,-1) as an ordered pair

Step-by-step explanation:

Question 1:

Solve them like an addition problem:

-4x-2y=-12

4x+8y=-24

________

(-4x+4x)+(-2y+8y)=(-12+-24)

0x+6y=-36

6y=-36

y=-6

Plug value of y into one of the original equations:

4x+8(-6)=-24

4x-48=-24

4x=24

x=6

Question 3:

Solve them like an addition problem:

x-y=11

2x+y=19

_______

(x+2x)+(-y+y)=11+19

3x+0y=30

3x=30

x=10

Plug value of x into one of the original equations:

10-y=11

-y=1

y=-1

Answers

Answer:

Step-by-step explanation:

y =  3x - 4

x = 0,  y = 3*0 - 4

          y = -4

(0 , -4)

x = 1 ,    y = 3*1 - 4

            y = 3 - 4

            y = -1

(1 , -1)

x = 2  , y = 3*2 - 4

           y = 6 - 4

           y = 2

(2 , 2)

Now mark these points (0 , -4) , (1 , -1) & (2 , 2) in the graph and join the points

how many liters are in 21 cups? if 1L=4.2cups
i don't understand how to do it

Answers

Answer:

5 L

Step-by-step explanation:

As given in question,

1 L can fill 4.2 cups.

So, 1 cup can hold [tex]\frac{1}{4.2}[/tex] L of fluid.

Therefore,

21 cups can hold = [tex]\frac{1}{4.2}[/tex] × 21

                            = 5 L

So, there is 5 L of fluid in 21 cups.

5 liters, because if you use divide 21 cups by 4.2 cups (1 liter), you will come out to 5 liters

There are 35 students in a drama club two out of every five boys in the club are boys how much diamonds in the club are boys

Answers

Given:

Number of students = 35

Two out of every five boys in the club are boys.

To find:

The number of students in the club that are boys.

Solution:

Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.

Let the number of boys be 2x and number of students be 5x.

According to the question,

[tex]5x=35[/tex]

[tex]x=7[/tex]

Now, the number of boys is

[tex]2x=2(7)[/tex]

[tex]2x=14[/tex]

Therefore, 14 students in the club are boys.

Answers

Answer:

Use 12 more pounds of pasta.

Step-by-step explanation:

A restaurant uses 3 pounds of pasta for a party of 14 people. If they are cooking pasta for a party of 56 people, what should they do?

Hence, we have:

14 people = 3 pounds of pasta

56 people = x

Cross Multiply

14 × x = 56 × 3

14x = 56 × 3

x = 56 × 3/14

x = 12 pounds of pasta

Hence, if they are cooking for 56 people they should use 12 pounds of pasta

1. 7 - 2 x 3 = 1

First, multiply 2 and 3 to get 6

7 - 6

Subtract the numbers to get 1

2. -8 + 14 / (-2) = -15

First, do 14 divided by -2 to get -7

-8 + -7

Add the two numbers to get -15

3. -6 + (-3) x 4 = -18

First, multiply -3 and 4 to get -12

-6 + -12

Add the two numbers together to get -18

4. 48 / (-12) +3 = -1

Divide 48 and -12 to get -4

-4 + 3

Add the two numbers to get -1

5. 16 / (-2) -3 = -11

Divide 16 by -2 to get -8

-8 - 3 = -8 + (-3)

Add the two numbers together to get -11

6. -11 x 4 / (-2) = 22

Work the problem from left to right, start with -11 x 4 to get -44

-44 / -2

Divide the equation to get 22

Mike's truck engine holds 1 and 1/4 gallons of oil if there are 3 quarts of oil in the engine now how many more quarts of oil does Mike need to fill the engine to capacity

Answers

Answer:

2 more quarts of oil is needed to fill

the engine to capacity

Step-by-step explanation:

Here, we want to calculate how many more quarts of oil is required to fill the engine to capacity

We have to convert the capacity to quarts

Mathematically, 1 gallon = 4 quarts

So 1 1/4 gallon will be 5/4 * 4 = 5 quarts

So the number of quarts needed to fill the engine to capacity will be 5 quarts - 3 quarts = 2 quarts

write an exponential function in the form y=ab^(x) that goes through points (0,4) and (6, 2916)

Answers

Answer:

y=4(3)^x

Step-by-step explanation:

The exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

What is the exponential function?

An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.

Given that, a graph of an exponential function is passing through, (0,4) and (6, 2916)

The exponential form of an equation is given by =

y = abˣ

Where, a is the y-intercept,

a = 4 here,

y = 4bˣ

Now substitute 6 for x and 2916 for y,

2916 = 4(b)⁶

b⁶ = 729

b = 3

Therefore,

y = 4(3)ˣ

Hence, the exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ
