Line a
y = 5x - 6, it has slope of 5Line b
x + 5y = 5Rewrite in slope-intercept form to find its slope:
5y = -x + 5y = -1/5x + 1It has slope of -1/5Lines have different slopes: 5 and -1/5, therefore are not parallel
Answer:
The answer to the question provided is False.
Step-by-step explanation:
‣We are going to have to find the value of y for line b.
‣We are going to solve its equation.
[tex]x + 5y = 5 \\ \frac{- x \: \: \: \: \: = - x}{ \frac{5y}{5} = \frac{ - x + 5}{5} } \\ y = - \frac{1}{5} x+ 1[/tex]
‣So we have:
[tex]y = 5x - 6 \\ and \\ y = - \frac{1}{5} x + 1[/tex]
‣Remember that a slope is parallel to another slope if it has the same slope.
‣A slope is perpendicular to another slope if it has a negative reciprocal.
‣The slopes we have don't have the same slope, but they are perpendicular.
The sum of two consecutive integers is 59. Write an equation that models this situation and find the values of the two integers.
A.
n + n + 1 = 59; n = 29; n + 1 = 28
B.
n + n + 1 = 59; n = 29; n + 1 = 30
C.
n + n + 1 = 59; n = 30; n + 1 = 31
D.
n + 2n = 59; n = 19; 2n = 38
Answer:
B
Step-by-step explanation:
n+(n+1)=59
2n=59-1=58
n=58/2=29
n+1=29+1=30

Your baseball team has won 6 game and lost 4 game.If the the team dosen;t lose anymore games how many games must the team win to have a win:the ration is 2:1 ? Explain your answer
Answer: 2 more games
Step-by-step explanation:
From the question, we are informed that a baseball team has won 6 game and lost 4 game.
We are further told that the team dosent lose anymore games and want to know the number of games they must win to have a ratio of 2:1.
Since they have lost 4 games and need a ratio of 2:1. This means we have to multiply the game lost by 2. This will be: = 4 × 2 = 8 games.
Since they've won 6 games already, they'll need to win = 8 - 6 = 2 games more.

What is the surface area of the right cone below?
Answer:
54 is anwer.
please mark me brainliest and follow me my friend.
because 54 is correct answer.
The value of surface area of the right cone is,
⇒ 54π units²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Radius of cone = 3 units
Slant height = 15 units
Now, The formula for the total surface area of a right cone is,
T. S. A = πrl + πr²
Hence, We get;
The value of surface area of the right cone is,
⇒ π x 3 x 15 + π x 3²
⇒ 45π + 9π
⇒ 54π units²
Thus, The value of surface area of the right cone is,
⇒ 54π units²

What is X+Y?? and ( x+ y)- 7+8
Step-by-step explanation:
What is X+Y?
First note that if x + y = xy then neither x nor y can be equal to 1.
That being said, as a previous user already noted y = x/(x-1) and hence x - y = x - x(x-1) = x(x-2)/(x-1). Assume x - y = D. Then your question becomes what can D be so that the equation x(x-2)/(x-1) = D has a solution different than 1.
Rewrite this equation as x(x-2) = D(x-1) and note that x(x-2) = (x-1)^2 - 1. Replace x - 1 with z. So your question is what can D be so that the equation z^2 - 1 = Dz has a nonzero solution? Given that 0 cannot be a solution anyway of the previous equation. The question is really, for which D does the quadratic equation z^2 - Dz - 1 = 0 have solutions? By elementary 9th grade math, this equation has a solution when its discriminant D^2 + 4 is nonnegative. But D^2 + 4 is strictly positive regardless of the value of D. Hence D can be anything.

Which of the following graphs in the xy-plane could be used to solve the system of equations above?
A system of equations is shown below.
y = 2x - 3
y = 5x + 6
What is the value of x + y?
A. -12
B. -9
C. 9
D. 12
Please help me!!!!
Answer:
-12
Step-by-step explanation:
Step1: Add 3 to both sides of the equation
2x -3 = 5x +6
+3 +3 = 9
Step2: subtract 5x from both sides of the equation
2x = 5x +9
-5 -5
Step3: divide both sides of the equation by the same term
-3x(/ -3) = 9(/-3)
X=-3Step4: multiply -3 with 2
-3x2= -6
Step4: subtract -6 with 3
-6 - 3= -9
Y=-9Step5: add the -9 to -3
-9 + -3 = -12

Bradley has ordered a steak from the meat market that weighs 1 5/8 pounds. There is a bone in the steak that weighs 7/8 of a pound. How much does the meat weigh?
Answer:
3/4
Step-by-step explanation:
the bone and the steak weigh = 1 5/8 pounds
The bone weighs 7/8
The meat weighs = 15/8 - 7/8
Converting 1 5/8 to an improper fraction gives 13/8
13/8 - 7/8 = 6/8 = 3/4

What is equation modelling? What is a mathematical equation and expression? Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the student council hires a dj to play music at the school dance. They pay DJ Dan for 3.5 h at his hourly rate plus a 125$ setup fee. the total cost is $405.
Assume that the hourly rate is $[x]. Than, we can write -
3.5x + 125 = 405
3.5x = 405 - 125
3.5x = 280
x = (280/3.5)
x = 80
Therefore, DJ Dan's hourly rate will be $80.
