To graph a straight line only 2 points are required

although 3 points are better (in case of error with other 2 .)

To find the y-intercept let x = 0 : hence y = - 5 ie (0 , - 5 )

To find the x-intercept let y = 0 : hence -x - 5 = 0 so x = - 5

ie ( - 5 , 0 )

These 2 points will allow the line to be drawn but a 3rd

is preferable. Choose any value for x and evaluate y.

choose x = 2 : then y = - 2 - 5 = - 7 ie (2 , - 7 )

Plot these 3 points: (0 , - 5 ) , (- 5 , 0 ) and (2 , - 7 ) and

draw a straight line through them .

Here is the graph of y = - x - 5

Queremos saber cuantas porciones de arroz se preparan dado que conocemos cuantos gramos de arroz se utilizan.

Se prepararon 68 porciones.

Lo que sabemos en principio es que, por cada porción de arroz, se necesitan 70 gramos de arroz.

Sabemos que en total se utilizan 4,760 gramos de arroz. Para saber cuantas porciones se prepararon, hay que tomar el cociente entre la cantidad total utilizada y lo que se usa para cada porción.

Esto nos da:

4,760g/70g = 68

Es decir, se prepararon 68 porciones.

Answer for 33 = 1, 3, 11, 33.

This is because all of those numbers divide into 33 evenly / are factors of 33.

Answer for 93 = 1, 3, 31, 93

This is because all of those numbers divide into 93 evenly / are factors of 93.

Answer:

1) composite: 1, 3 , 11 , 33

2) composite 1, 3, 31, 93

Step-by-step explanation:

1) We know that 33 is divisible by 3 because the whole value is equal to 6, and the last digit is a 3.

2) We know that 93 is divisible by 3 because the last digit was 3, and all of the place values added up to 12, which is also divisible by 3.

Answer:

A) -0.0125

Step-by-step explanation:

-1/80 (fractional form)

Answer:

4/3 or 1 1/3

Step-by-step explanation:

So if y = 6, when x = 2/3. Then, x would equal 1 and 1/3, because 12 is twice the amount of 6, so you'd also multiply 2/3 by 2.

(To multiply a whole number by a fraction, first multiply the whole number by the numerator and then divide that by the denominator. For example: 2 × 2 = 4, since you can't really divide 4 by 3 it would stay as is, but you can turn it to a mixed number. 4/3 is the same as 1 whole and an extra 1/3, or in other words 1 1/3).

Answer:

(x, y) = (57/4, 31/4)

Step-by-step explanation:

-2x + 6y = 18

-2x = 18 - 6y

x = -9 + 3y

3(-9 + 3y) - 5y = 4

-27 + 9y - 5y = 4

4y = 31

y = 31/4

x = -9 + 3(31/4) = 57/4

Answer:

Step-by-step explanation:

-5y=4-3x

y=(4/-5)-(3/-5x)

2x+6y=18

6y=18-2x

y=18/6-(2/6x)

y=y

(4/-5)-(3/-5x)=18/6-(2/6x)

0.93x=3.8

x=3.8/0.93

x=4.09

sub 4.09 for the 3x-5y=4

which will give you y=1.65

sub 4.09 for -2x+6y=18

which will give you y=4.36

Answer:

From 1st eqn .,

3x=4+5y

X=4+5y/3

From 2nd eqn ..,

-2x+6y=18

-2(4+5y/3)+6y=18

-8+10y/3 +6y=18

-8+10y+18y/3=18

-8+28y/3=18

-8+28y=54

28y=54+8

y=62/28

y=31/14

Therefore the value of y is 31/14

Again,

Putting the value of y in ..

X=4+5y/3

=(4+5*31/14)/3

=(211/14)/3

=211/42

Step-by-step explanation:

So the value of X and y is 31/14 &211/42 respectively.

Answer:

x = 1 , y = 4

Step-by-step explanation:

I am assuming you're looking for what x and y are? If so, then we know that

DC and AB equal each other, so

4x + y = 8

CB and AD equal each other, so

2x + y = 6

We have two equations that cannot be solved on their own, so we must solve them as a system of equations. One process to solve is elimination.

4x + y = 8

2x + y = 6

we can multiply the second equation all by -1 to make the y's cancel out and give us x. so,

4x + y = 8

-1(2x + y) = 6

4x + y = 8

-2x -y = -6

now solve them vertically. we get:

2x = 2

and so x = 1.

Now that we found x, we must find y. Using any of the two equations froom above, we can substitue our x value of 1 into it to find y. I will use the first one.

4x + y = 8

4(1) + y = 8

4 + y = 8

y = 8 - 4

y = 4

so our x is 1 and y is 4.

Answer:

subtract 20 from both sides

Step-by-step explanation:

1. To find the answer, let's actually try solving the equation first and find the 2nd step.

2. (Solving)

Step 1: Distribute 2 to each term.

Step 2: Subtract 20 from both sides.

3. Since we got that the second step was "subtract 20 from both sides," the answer is subtract 20 from both sides.

Answer:

252, 585, 6750

Step-by-step explanation:

We have to think that the regular price represents 100% and we need 10 of 10% to make an 100%. So if we divide the regular price by 10 will get our 10%.

i) A CFL bulb if the marked price is Rs. 280

10 % of 280 is 280/10 = 28

discounted price is 280 -28 = 252

ii) A bunion if the marked price is Rs. 650.

10 % of 650 is 650/10 = 65

discounted price is 650 -65 = 585

iii) A gas cooker if the marked price is Rs. 7500

10 % of 7500 is 7500/10 = 750

discounted price is 7500 -750 = 6750
