Answer:

B

Step-by-step explanation:

The slope of this graph which is the unit rate = 18/4 = 4.5 This graph goes through 0,0 and (4,18) and the unit rate = y /x

The value of x and y  for the given equation by elimination method are 1 and 1 respectively.

The elimination method is the process of eliminating on of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

According to the given question

We have two equations

[tex]2x -y =1...(1)[/tex]

[tex]x+3y-4=0...(2)[/tex]

Multiply equation (1) both the sides by 3

[tex]6x - 3y =3...(3)[/tex]

Adding equation (2) and (3)

[tex]6x+-3y+x+3y -4 =3\\7x =7\\x =1[/tex]

Substitute

x =1,  in either 2x -y =1 or x + 3y -4 =0

2(1) - y =1

⇒ -y = 1 -2

⇒ -y = -1

⇒ y =1

Hence, the value of x  and y is 1 and 1 respectively.

Answer:

A normal is an object such as a line or vector that is perpendicular to a given object. ... If normal is 90 degree to the surface, that means normal is used in 3D. Perpendicular in that case is more in 2D referring two same entities (line-line) with 90 degree angle between them.

Answer:

Blood groups are inherited from both parents. ... Individuals with IAIA or IAi have type A blood, and individuals with IBIB or IBi have type B. IAIB people have both phenotypes, because A and B express a special dominance relationship: codominance, which means that type A and B parents can have an AB child.

Answer:

The rational function is [tex]f(x) = \dfrac{x^2 + 8\cdot x - 9}{x^2 - 4 \cdot x + 3}[/tex]

The horizontal asymptote occur at y = 1

Step-by-step explanation:

Given that the function has an x-intercept at (-9, 0), we have;

(x + 9) is a factor of the function

Also, given that the function has a vertical asymptote at x = 3, we have that a factor of the denominator of the function is (x - 3)

With a hole at (1, -5), we have, (x - 1) in both the numerator and the denominator and when x = 1, f(x) = -5

The general form of the function can be presented as follows;

f(x) = ((x + 9)·(x - 1))/((x - 3)(x - 1)) = (x² + 8·x - 9)/(x² - 4·x + 3)

Given that the power of the numerator and the denominator are equal, the horizontal asymptote occur at ratio of the leading coefficient of the numerator and the denominator which from the above equation is 1/1 = 1

The horizontal asymptote occur at y = 1

Step-by-step explanation:

There are many ways to figure it out but if you multiply by 20 each you'll get 40/100=40%

Answer:

c: 2/5

Step-by-step explanation

40% ÷10= 4÷2=2

100%÷10=10÷2=5

So you do 40% over 100% and divide both by 10 then simplify it and 2 goes into both 4 and 10 so you divide by 2 and get 2/5

Step-by-step explanation:

Start by adding the number in the parenthesis: This gives us (8(11)/2^2) + 6(2)

Square the bottom: (8(11)/4) + 6(2)

Multiply the top of the fraction: (88/4) +6(2)

Divide 88 by 4: 22 + 6(2)

Multiply 6 and 2: 22 + 12

Add 22 and 12: 22 + 12 = 34

Answer:

x = 22°

w = 30°

y = 30°

z = 52°

Step-by-step explanation:

From ΔACD,

AD is the diameter and ∠ACD is the angle subtended by the diameter.

Therefore, m∠ACD = 90°

By triangle sum theorem,

m∠DAC + m∠ACD + m∠CDA = 180°

w° + 90° + 60° = 180°

w = 180 - 150

w = 30°

AB║ED and AD is a transversal line.

Therefore, m∠BAD = m∠ADE

(w + 22)° = z°

30 + 22 = z

z = 52°

Since, ∠CEB and ∠BAC are the inscribed angles subtended by the same arc BC,

Therefore, m∠CEB = m∠BAC

x = 22°

Similarly, ∠CED and ∠DAC are the inscribed angles subtended by the same arc CD,

m∠CED = m∠DAC = 30°

y = 30°
