Step-by-step explanation:

Step 1: Define Systems

y = x + 2

3x + 3y = 6

Step 2: Solve for x

Substitution

Substitute in y [2nd Equation]:                                                                         3x + 3(x + 2) = 6[Distributive Property] Distribute 3:                                                                 3x + 3x + 6 = 6Combine like terms:                                                                                         6x + 6 = 6[Subtraction Property of Equality] Subtract 6 on both sides:                        6x = 0[Division Property of Equality] Divide 6 on both sides:                                  x = 0

Step 3: Solve for y

Substitute in x [1st Equation]:                                                                           y = 0 + 2Add:                                                                                                                   y = 2
Answer 2

Answer:

(0, 2)

Step-by-step explanation:

Since y is x + 2, we can replace y with x + 2

3x + 3y = 6

3x + 3(x+2) = 6

3x + 3x + 6 = 6

6x + 6 = 6

6x = 0

x = 0

y = x + 2

y = 2

Now we can check by replacing x with 0

3x + 3y = 6

3(0) + 3y = 6

0 + 3y = 6

3y = 6

y = 2

An ordered pair is represented as:

However, for the ordered pair to be a function; all the x values must be unique (i.e. not repeated)

From options (a) to (d), option (b) has -6 repeated twice. Hence, it is not a function.

Answers

Answer:

3) 109.27

4) 58.80

5) 48.65

Step-by-step explanation:

First divide the cost by the number of units to get the individual cost of each item.

Then multiply by the new number of units.

For example:  78.05 ÷ 5 = 15.61 for each.

                       15.61 x 7 = 109.27

The rate of electricity charge up to 20 units is Rs 3 per unit and Rs 7 per unit from 21 to 30 units. If a family paid the bill of Rs 166 with Rs 50 service charge, how many units of electricity was consumed in the month?​

Answers

Answer:

28units consumed in month

Step-by-step explanation:

20unit=20×3=60rs

now service charge +60rs=110

similary total paid=166

now 166-110=56

and 56/7=8unit

since total unit=28unit

An angle measures 42.2° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

x + (x-42.2) = 90

2x - 42.2 = 90

add 42.2 to both sides

2x = 132.2

divide each side by 2

x = 66.1

find the measure of the other angle

66.1 - 42.2 = 23.9

Step-by-step explanation:

Answer:

66.1° and 23.9°

Step-by-step explanation:

Complementary angles are angles that sum up to 90°

So equation : x + x - 42.2 = 90

2x - 42.2 = 90

2x = 132.2

x = 66.1

66.1° is the "other complementary angle"

This angle is 66.1 - 42.2 = 23.9°

A oil company has a large tank that holds the oil before it is distributed. If it costs $3.20 per cubic meter for oil, how much money would it cost to fill the entire tank?

A. $65,280
B. $68,000
C. $5,440
D. $67,200

Answers

Answer:

Option A, $65,280

Step-by-step explanation:

The volume of the tank is,

12×20×15+40×(50-15)×12

= 3600+16800

=20400 cubic meters

For each cubic meter, it costs $3.20, so for 20400 cubic meters it'll cost,

20400×$3.20

= $65,280

What is the slope of the line? What is the y-intercept of the line? y = -3x + 4

Answers

Answer:

slope= -3/1

y-intercept= 4

Answer:

m = -3

Step-by-step explanation:

The given equation of the line is ,

[tex]\implies y = -3x+4[/tex]

We know that the Standard equation of Slope Intercept Form of the line is,

[tex]\implies y = mx + c[/tex]

Where ,

m is slope c is y intercept

Sam rolls a fair dice and flips a fair coin.
What is the probability of obtaining an odd number and a head?

Answers

Answer:

1/4

Step-by-step explanation:

Given an event A and event B, the probability of both happening can be determined by multiplying the two individual probabilities.

We can start by finding the individual probabilities

The probability of rolling an odd number is 3/6 = 1/2, as there are 3 odd numbers (1,3,5) on a die and 6 possibilities total. Furthermore, there is a equal chance of rolling each number as it is a fair die

The probability of flipping a head is 1/2, as there are two equal possibilities (heads and tails), with one of them being heads

To find the probability of both happening, we can multiply them to get (1/2) * (1/2) = 1/4

Pedro preparou 4kg de salada de frutas, que serviu igualmente entre 16 convidados. Quantos kg de salada de frutas cada convidado recebeu?

Answers

Answer: The amount of salat received by each guest is 0.25 kg

Step-by-step explanation:

We are given:

Mass of the fruit salad prepared = 4 kg

Total number of guests = 16

As the salad was divided equally amongst the guest, so when we divide the mass by the number of guests, we will get the amount of salad received by each guest.

Amount received by each guest = [tex]\frac{4kg}{6}=0.25kg[/tex]

Hence, the amount of salat received by each guest is 0.25 kg

180-(37+90)

180-127

53

180-(54+53)

=180-107

=73°

Answer:

Step-by-step explanation:

AC = AD So,  Δ ACD is as isosceles triangle.

∠ADC ≅∠ACD = 63°

In ΔACD ,

    63 + 63 + ∠DAC = 180   {Angle sum property of triangle}

            126 + ∠DAC = 180

                     ∠DAC = 180- 126

                     ∠DAC = 54°

In ΔABC,

90+ 37 + ∠CAB = 180

        127 + ∠CAB = 180

                 ∠CAB = 180 - 127

                 ∠CAB = 53

∠EAD + ∠DAC + ∠CAB = 180   {Straight line angles}

x + 54  + 53 = 180

        x + 107  = 180

                  x = 180 -107

x = 73°

I believe your answer would be B. because when it’s at year 0 it’s at 5, which is the y intercept. so it makes sense for it to answer B. sorry if i’m wrong but i hope it helps!

Answer:

B.

Step-by-step explanation:

f(t) = 5 * 2^t

At the y-intercept, t = 0.

f(0) = 5 * 2^0

f(0) = 5 * 1

f(0) = 5

At time = 0, the coin is worth $5.

The value of the y-intercept is the value of the coin at time = 0, which is when the coin was purchased.

Answers

Given :-

A car travels at an average speed of 40 km/h for 0.5 hours.

To Find :-

The distance travelled.

Solution :-

We know that ,

→ Distance = Speed × Time

So that ,

→ Distance = 40 km/hr × 0.5 hr

→ Distance = 40km/hr × 1/2 hr

→ Distance = 20km .

Hence the required answer is 20km .
