The correct statement for the equation of the line is the line passes through the ordered pair (0,5) and has a slope of 3.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Compare the given equation of the line y = 3x + 5 with the general equation.
y = mx + c
y = 3x + 5
The slope, m = 3
y-intercept = 5

A survey was carried out on 40 travelers . 12 of them said they had traveled to Ghana and not to Cameroon. 8 said they had travelled to Cameroon and not Ghana. 10 said they had not traveled to either one of the countries. Draw a Venn diagram to find 1. The number of travelers that had gone to both countries before. 2. The number of travelers that had gone to Ghana before.
It’s urgent.
Answer:
10 ; 22
Step-by-step explanation:
Ghana = G
Cameroon = C
Cameron only = 8
Ghana only = 12
Total sampled = 40
Both Ghana and Cameroon = x
Not traveled to either = 10
Ghana only + Cameroon only + both Ghana and Cameroon + not traveled to either = total sampled
12 + 8 + x + 10 = 40
30 + x = 40
x = 40 - 30
x = 10
Number that had gone to Ghana before :
Ghana only + both
12 + x
12 + 10
= 22

Find the equation of a line perpendicular to -3x + 5y = -1 that contains the point (0, -5)
Answer:
y = -5/3x - 5
Step-by-step explanation:
convert -3x + 5y = -1 to slope-intercept form:
5y = 3x - 1
y = 3/5x - 1/5
slope of a line perpendicular to the above equation would be -5/3
y = mx + b
-5 = -5/3(0) + b
b = -5
y = -5/3x - 5

What is the least common denominator of the rational expressions below?
1/x^2 - 4/3x^2+15x
Answer:
The LCD is 3x²
The other two denominators can be factors of 3x²
Step-by-step explanation:
To get the equivalent fractions, divide the original denominator into the LCD, then multiply the original numerator by the quotient.
For the first term: 1/x²
3x² ÷ x² = 3 3×1=3 The equivalent is 3/3x²
Second term: Leave it as it is.
For the third term: 15x
The implied denominator is 1
3x² ÷ 1 = 3x² 3x² × 15 = 135x²
The equivalent is 135x²/3x²
To check the validity, substitute a value for x and calculate the numbers.
For example let x = 3
The original expression becomes
1/3² + 4/3(3²) - 15(3)
1/9 + 4/27 - 45
With the LCD it is
3/27 + 4/27 - 1215/27

pedro y louis tiene 30 cromos. louis le dice a pedro 'dame 8 cromos para tener los mismos que tu'
cuantos cromos tiene cada uno.
Answer:
Pedro tiene 23 cromos y Luis 7.
Step-by-step explanation:
Sabemos que Pedro y Luis tienen (entre ambos) 30 cromos.
Definamos:
P = número de cromos que tiene Pedro
L = número de cromos que tiene Luis.
Entonces P + L = 30
Y sabemos que si Pedro le da 8 cromos a Luis, entonces ambos van a tener la misma cantidad de cromos.
Cuando Pedro da 8 cromos, el va a tener P - 8 en total
Cuando Luis recibe 8 cromos, el va a tener L + 8 en total
Entonces: P - 8 = L + 8
Tenemos dos ecuaciones:
P + L = 30
P - 8 = L + 8
Esto es un sistema de ecuaciones, para resolverlo el primer paso es aislar una variable en una de las ecuaciones, yo voy a aislar P en la primera:
P = 30 - L
Ahora podemos reemplazar esto en la otra ecuación para obtener:
(30 - L) - 8 = L + 8
Y podemos resolver esto para L.
30 - L - 8 = L + 8
22 - L = L + 8
22 - 8 = L + L
14 = 2*L
14/2 = L
7 = L
Entonces Luis tiene 7 cromos, y reemplazando esto en cualquiera de las dos ecuaciones que teníamos originalmente podemos encontrar el valor de P.
P + L = 30
P + 7 = 30
P = 30 - 7 = 23
Pedro tiene 23 cromos.

Answer:
96%
Step-by-step explanation:
assume the whole number is x
the first thing is decreasing by 20 %
x - 20%x = 80% x
then now the 80%x is the whole number
now It's the turn of increasing
80%x + 20% * (80% x) = 80%x + 16%x = 96% x

Which expression is undefined?
Answer:
C. 4/0
Step-by-step explanation:
You can't divide 4 by 0.
A. you would have gotten -0.5
B. you would have gotten 0
D. you would have gotten 0
Hope this help!! :)
Answer:
C. [tex]\frac{4}{0}[/tex]
Step-by-step explanation:
you cannot divide by zero, therefore option C is the correct choice because [tex]\frac{4}{0}[/tex] means 4 ÷ 0.
if 0 was the numerator, like in [tex]\frac{0}{4}[/tex] or 0 ÷ 4, the answer would be 0 because 0 divided by 4 is 0. this can be kind of confusing at times, but just remember that as long as 0 is the denominator in a fraction (meaning the 0 is under the fraction bar), the answer will always come out as undefined because you can't divide by 0.

-18 = –1(x – 11) solve this equation
Answer:
X= 29
Step-by-step explanation:
Answer:
x = 29
Step-by-step explanation:
Let's solve your equation step-by-step.
−18=−1(x−11)
Step 1: Simplify both sides of the equation.
−18=−1(x−11)
−18=(−1)(x)+(−1)(−11)(Distribute)
−18=−x+11
Step 2: Flip the equation.
−x+11=−18
Step 3: Subtract 11 from both sides.
−x+11−11=−18−11
−x=−29
Step 4: Divide both sides by -1.
-x/1 = -29/-1

The perimeter of a rectangular sheet is 100 cm. if the length is 35 cm, find its breadth. Also find the area.
Answer:
breadth: 15, area: 525
Step-by-step explanation:
Answer:
Breadth = 15cm
Area = 525cm^2
Step-by-step explanation:
We know that the perimeter of a rectangluar sheet is 100cm, and we know that the length is 35cm. We are then being asked to find the breadth and the area.
Use the information that we know to solve the breadth, get b alone :
Length = 35cm
2(l + b) = 100
Substitute :
2(35 + b) = 100
Divide 2 from both sides :
35 + b = 50
Subtract 35 from both sides :
b = 15cm
Now for the area :
Area = Length * Breadth
Substitute :
A = 35 * 15
A = 525cm^2
