Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

3x - y = 10

2x - y =  7

Step 2: Rewrite Systems

3x - y = 10

Subtract 3x on both sides:                    -y = 10 - 3xDivide -1 on both sides:                         y = 3x - 10

Step 3: Redefine Systems

y = 3x - 10

2x - y = 7

Step 4: Solve for x

Substitution

Substitute in y:                    2x - (3x - 10) = 7Distribute -1:                        2x - 3x + 10 = 7Combine like terms:           -x + 10 = 7Isolate x term:                     -x = -3Isolate x:                              x = 3

Step 5: Solve for y

Define equation:                    3x - y = 10Substitute in x:                       3(3) - y = 10Multiply:                                  9 - y = 10Isolate y term:                         -y = 1Isolate y:                                 y = -1

a retailer makes a profit of 5% by selling a fan for Rs 735 at what price did he purchase the fan​​

Answers

Answer:

[tex]\large\boxed{\pink{\sf \leadsto He \ purchased \ the \ fan \ for \ Rs 700. }}[/tex]

Step-by-step explanation:

Given that , a retailer makes a profit of 5% by selling a fan for Rs 735 . So let us take CP be x .

Now , here

[tex]\implies \red{\sf Profit \ made \ by \ retailer = 5\% }[/tex]

Here we assumed CP to be x , and profit % is 5% . So , its SP will be

[tex]\implies SP = CP + 5\% \ of \ CP \\\\\implies Rs 735 = x + \dfrac{5}{100}x \\\\\implies \dfrac{100x+5x}{100}= Rs 735 \\\\\implies \dfrac{105x }{100}= Rs 735 \\\\\implies x = \dfrac{735\times 100}{105} \\\\\underline{\boxed{\orange{\tt \implies x = Rs 700 }}}[/tex]

Hence the CP of the fan was Rs 700 .

Step-by-step explanation:

Sum of angles in a triangle = 180°

Angle W = 180° - 62° - 57° = 61°

The shortest side is directly opposite the smallest angle.

(for acute angles)

Hence the shortest side is opposite 57°, which is VW.

Answer:

VUW

62 + 57 + x = 180

119 + x = 180

x = 180 -119

x= 61

therefore smallest angle is 57° (vuw)

Step-by-step explanation:

h (x) =4x-2 complete the function table

Answers

Note:

You did not mention the table of the points. But, I would try to clear your concept by taking 6 sample points.

Answer:

The table and the graph of the function h(x) = 4x-2 is also attached below.

Step-by-step explanation:

Given the function

[tex]h(x) = 4x-2[/tex]

substituting x = 0 in the function

h(0) = 4(0) -2 = 0 -2 = -2

Therefore, the point (0, -2) satisfies on the function.

substituting y = 1 in the function

h(1) = 4(1) -2 = 4 -2 = 2

Therefore, the point (1, 2) satisfies on the function.

substituting y = 2 in the function

h(2) = 4(2) -2 = 8 -2 = 6

Therefore, the point (2, 6) satisfies on the function.

substituting y = 3 in the function

h(3) = 4(3) -2 = 12 -2 = 10

Therefore, the point (3, 10) satisfies on the function.

substituting y = 4 in the function

h(4) = 4(4) -2 = 16 -2 = 14

Therefore, the point (4, 14) satisfies on the function.

substituting y = 5 in the function

h(5) = 4(5) -2 = 20 -2 = 18

Therefore, the point (5, 18) satisfies on the function.

Therefore, we conclude that table:

x                  h(x) = 4x-2

0                  -2

1                    2

2                   6

3                   10

4                   14

5                   18

The graph of the function h(x) = 4x-2 is also attached below.

O C. x>-3 or xs 2
O D. x > 3 and xs3

Answers

Answer:

c) x > -3 or x ≤ 2

Step-by-step explanation:

We are asked to solve this algebraic expression

-9 < 4x+3 ≤ 11.

We have two parts:

a) -9 < 4x+3

b) 4x+3 ≤ 11

For

a) -9 < 4x+3

Subtract 3 from both sides

-9 - 3 < 4x + 3 -3

-12 < 4x

-12/4 < x

-3 < x

x > -3

b) 4x+3 ≤ 11

Subtract 3 from both sides

4x + 3 -3 ≤ 11 - 3

4x ≤ 8

x ≤ 8/4

x ≤ 2

Hence, our answer is

x > -3 or x ≤ 2

Megan went to the store and bought 4 notebooks and 9 pencils for a total of $8.25. Joanne went to the same store and bought 7 notebooks and 14 pencils for a total of $14. What was the price per pencil and the price per notebook?

Answers

Let notebooks be x and let pencils be y

4x+9y=8.25 (equation 1)
7x+14y=14.00 (equation 2)

Multiply equation 1 by 7
So that you get 28x+63y=57.75

Multiply equation 2 by 4
So that you get 28x+56y=56.00

28x+63y=57.75 -
28x+56y=56.00
-----------------------
7y=1.75

Divide both sides by 7
1.75/7 is 0.25

So, now we know that one pencil costs 0.25 cents

Sub this y value into equation one

4x+9(0.25)=8.25

4x+2.25=8.25

Move 2.25 to the other side as a negative number

4x= 6

Divide both sides by 4

6/4 is $1.50

So, one pencil is equal to 0.25 cents and one notebook is equal to $1.50

Put the arrow facing the left with a non-filled up dot at the point between 31 and 32.

Step-by-step explanation:

x < 31.5 means that x is lesser than 31.5 and so x cannot be 31.5 itself.

< means lesser.

> means more than.

A filled up dot means that the number itself is included in the values of x.

A non-filled up dot means that the number itself is not included in the values of x.

An arrow facing left means lesser than that number.

An arrow facing right means more than that number.

Since 31.5 is not included in the values of x, we will be using the non-filled up dot.

Two rectangle are similar, the first 4 in wide and 15 in long. The second is 19 in. Wide. Find the length of the second rectangle?

Answers

Answer:

the length of the second rectangle is 33.75 in

Step-by-step explanation:

The computation of the length of the second rectangle is as follows

Let us assume the length of the second triangle be x

Now

The equation would be

4 ÷ 15 = 9 ÷ x

Now do the cross multiplication

4x = 15 × 9

4x = 135

x = 33.75 in

Hence, the length of the second rectangle is 33.75 in



MAKING AN ARGUMENT You and a friend are going hiking but start at different locations. You start at the trailhead and walk 5 miles per hour. Your friend

situation.

Answers

Answer:

[tex]y = 5x[/tex] -- You

[tex]y = 3 + 3x[/tex] --- Your friend

Step-by-step explanation:

Given

You:

Trailhead implies the beginning so:

[tex]Start = 0\ mile[/tex]

[tex]Rate = 5miles/hour[/tex]

Your Friend

[tex]Start = 3\ mile[/tex]

[tex]Rate = 3miles/hour[/tex]

Required

Represent as an equation

From the question, we understand that:

[tex]y = distance[/tex]

[tex]x = number\ of\ hours[/tex]

So, the relationship between [tex]distance\ and\ time\ is:[/tex]

[tex]Distance = Start + Rate * Number\ of\ hours[/tex]

In terms [tex]of\ x\ and\ y[/tex], we have:

[tex]y = Start + Rate * x[/tex]

For you, the equation becomes:

[tex]y = 0+ 5* x[/tex]

[tex]y = 0+ 5x[/tex]

[tex]y = 5x[/tex]

For your friend, the equation becomes:

[tex]y = 3 + 3 * x[/tex]

[tex]y = 3 + 3x[/tex]

Answers

Answer:

The range for points scored is greater than the range for points allowed.

Step-by-step explanation:

Points scored: 175

Points allowed: 168

The true sentence is that the range for points scored is greater than the range for points allowed.

What is mean?

The mean of observations is equal to the ratio of sum of all the observations and the number of observations.

Points scored by the lion in the 8 games are

24 + 21 + 18 + 17 + 24 + 31 + 22 + 28 = 175.

Points allowed in the 8 games are

16 + 10 + 27 + 21 + 21 + 24 + 28 = 168

Thus, the range for points scored is greater than the range for points allowed.​
