Answer:

2x+1=y

Step-by-step explanation:

Parallel means has the same slope, so slope equals 2

2x+b=y (we don't know the y-intercept)

plug in x and y

2(-4)+b=-7

-8+b=-7

b=1

so, 2x+1=y

The value of the simplified expression is 4.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

18 - 6 (2 + 4 - 1 + 2) ÷ 3

Apply the PEMDAS rule.

P = Parenthesis

E = exponents

M = Multiplication

D = Division

A = addition

S = Subtraction

Step 1:

18 - 6 (8 - 1) ÷ 3 ( remove the parentheses )

18 - 6 x 7 ÷ 3

Step 2:

18 - 42 ÷ 3 ( Multiplication )

Step 3:

18 - 42/3 (Division)

18 - 14

Step 4:

18 - 14 ( Subtraction )

4

Thus,

The value of the expression is 4.

Answer:

Figure 4.

Step-by-step explanation:

It is figure 4 because they are equal length away from each other.

We cannot write [tex]\sqrt{103}[/tex] as a ratio of integers, so that's why it's irrational.

Note that [tex]\sqrt{103} \approx 10.1488915650922[/tex]

The decimal digits go on forever without any pattern. If the digits repeated themselves, then we would have a rational number.

A quick way to tell if it is rational or not, without using a calculator, is to note that 103 is not a perfect square. The list of perfect squares are:

1,4,9,16,25,36,49,64,81,100,121,...

we see that 100 is the closest perfect square, but 103 is not in that list. Each perfect square is of the form x^2, where x is some positive whole number.

Answer:

Yes this is irrational like the guy above me said you cannot write it as a ratio, of integer since rational numbers are:

A rational number is any integer,

fraction,

terminating decimal,

or repeating decimal.

So its Not Rational

Answer:

x = 41.67

Step-by-step explanation:

The above equation, would be simplified or divided into parts;

Therefore, the given equation becomes;

A/x = B/C

Where;

A = (15.2*0.25-48.51/14.7)

B = (13/44-2/11-5/66/2.50)1.2

C = 3.2+0.8(5.5-3.25)

x = unknown variable.

Part A

(15.2*0.25-48.51/14.7) = (15.2*0.25 - 3.3)

A = (3.8 - 3.3)

A = 0.5

Part B

(13/44-2/11-5/66/2.50)1.2 = (0.3 - 0.18 - 0.030) * 1.2

B = 0.09 * 1.2

B = 0.108

Part C

(3.2+0.8(5.5-3.25)

C = 4*(2.25)

C = 9

Substituting the values into the equation, we have;

0.5/x = 0.108/9

Cross-multiplying, we have;

9 * 0.5 = 0.108x

4.5 = 0.108x

x = 4.5/0.108

x = 41.67

Answer:

The triangles are congruent by SAS.

Step-by-step explanation:

The triangle have two congruent sides because it is given. The congruent angle is the angle at which they connect, these two angles are congruent because they are vertical angles.

Answer:

Step-by-step explanation:

Circumcenter of A triangle is the center of a circle passing through the vertices of the given triangle.

So, the distance of Z from the vertices Q, R and S will be the radii of the circle.

Therefore, ZQ = ZR = ZS

Since, circumcenter of a triangle is defined by the point of intersection of the perpendicular bisectors of the sides of the given triangle.

Therefore, points W, X and Y are the midpoints of sides QR, RS and QS.

Using these facts,

a). QR = 2(WQ)

          = 2(25)

          = 50

b). Apply Pythagoras theorem in ΔRXZ,

    (RZ)² = (RX)² + (ZX)²

    (RZ)² = (40)² + (9)²

     RZ = √1681 = 41

c). XS = [tex]\frac{1}{2}(RS)[/tex]

          = [tex]\frac{1}{2}(80)[/tex]

          = 40

d). Since, ZQ = ZR = ZS

    ZS = 41

e). By applying Pythagoras theorem in ΔRWZ,

   (RZ)² = (WZ)² + (WR)²

   (41)² = (WZ)² + (25)²

   (WZ)² = (41)² - (25)²

    WZ = √1056

   WZ = [tex]4\sqrt{66}[/tex]

          ≈ 32.5

Applying the circumcenter theorem and the Pythagorean Theorem, the following measures are calculated as:

a. QR = 50

b. RZ = 41

c. XS = 40

d. ZS = 41

e. WZ = 32.5

Based on the circumcenter theorem of a triangle, the following holds true given that Z is the circumcenter of triangle QRS:

Given:

a. Find QR:

QR = 2 × WQ = 2 × 25

QR = 50

b. Find RZ in right ΔXRZ:

XZ = 9 (given)

XR = 1/2(RS) = 1/2(80) = 40

RZ = √(XZ² + XR²)

RZ = √(9² + 40²)

RZ = 41

c. Find XS:

XS = 1/2(RS) = 1/2(80)

XS = 40

d. Find RZ:

RZ = ZS = QZ = 41 (equidistant)

ZS = 41

e. Find WZ in right ΔWRZ:

WR = WQ = 25

WR = 25

RZ = 41

WZ = √(RZ² - WR²)

WZ = √(41² - 25²)

WZ = 32.5

25+25+25+1+1=77cents

Tuesday-2 dimes (dimes are 10cents) plus 1 nickel (nickels are 5cents)

An exchange rate tells you the value of your currency in another currency.

Given that, Lakshmi wants to start saving coins in a piggy bank. Her mother gave her 3 quarters and 2 pennies on Monday and 2 dimes and 1 nickel on Tuesday.

Monday- 3 quarters (quarters are 25 cents) plus 2 pennies (pennies are 1 cent each)

25+25+25+1+1=77 cents

Tuesday- 2 dimes (dimes are 10 cents) plus 1 nickel (nickels are 5 cents)

10+10+5=25 cents

Given:

Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee.

Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee.

To find:

The number of months after which the costs for the girls’ cell phone plans the same.

Solution:

Let x be the number of months.

Total cost = Fixed cost + Variable cost

According to the question, cost equation for Anna’s cell phone is

[tex]y=150+30x[/tex]           ...(i)

Cost equation for Evelyn's cell phone is

[tex]y=450+20x[/tex]         ...(ii)

Equate (i) and (ii) to find the time after which the costs for the girls’ cell phone plans the same.

[tex]150+30x=450+20x[/tex]

[tex]30x-20x=450-150[/tex]

[tex]10x=300[/tex]

Divide both sides by 10.

[tex]x=\dfrac{300}{10}[/tex]
