Answer:
2x + 5y = -4
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
========================================================
Explanation:
Let's use point slope form to get
y - y1 = m(x - x1)
y - y1 = -4(x - x1) .... plug in the given slope m = -4
y - 5 = -4(x - 2) .... plug in the given point (x1,y1) = (2,5)
Now we isolate y
y - 5 = -4(x - 2)
y - 5 = -4x + 8
y = -4x + 8 + 5
y = -4x + 13
This equation is in slope intercept form y = mx+b
m = -4 is the slope
b = 13 is the y intercept
To get this into standard form, we add 4x to both sides so that the x and y terms are on the left side
y = -4x+13
y+4x = 13
4x + y = 13 is the final answer
This is in standard form Ax+By = C where
A = 4
B = 1
C = 13
--------------------------
Let's check the answer. Plug in (x,y) = (2,5) to find that...
4x+y = 13
4*2 + 5 = 13
8 + 5 = 13
13 = 13
We get the same thing on both sides, so the last equation is true. This means the first equation is true when (x,y) = (2,5). This confirms the point (2,5) is on the line and helps confirm the answer.

Answer:
The equation of required line is: [tex]\mathbf{5x-8y+34=0}[/tex]
Step-by-step explanation:
We need to write equation in the form Ax+By+C=0 of the line parallel to [tex]5x-8y+12=0[/tex] and through the point (-2,3)
First we need to find slope and y-intercept of the required line.
Using equation of line [tex]5x-8y+12=0[/tex] to find slope.
Since the given line and required lines are parallel there slope is same.
Writing equation in slope intercept form: [tex]y=mx+b[/tex] where m is slope.
[tex]5x-8y+12=0 \\-8y=-5x-12\\\frac{-8y}{-8y}=\frac{-5x}{-8}-\frac{12}{-8}\\y=\frac{5}{8}x+\frac{3}{4}[/tex]
So, the slope m = 5/8
The slope of required line is [tex]m=\frac{5}{8}[/tex]
Now finding y-intercept using slope [tex]m=\frac{5}{8}[/tex] and point(-2,3)
[tex]y=mx+b\\3=\frac{5}{8}(-2)+b\\3=\frac{-5}{4}+b\\b=3+\frac{5}{4}\\b=\frac{3*4+5}{4}\\b=\frac{12+5}{4}\\b=\frac{17}{4}[/tex]
So, the equation of required line having slope [tex]m=\frac{5}{8}[/tex] and y-intercept [tex]b=\frac{17}{4}[/tex]
[tex]y=mx+b\\y=\frac{5}{8}x+\frac{17}{4}\\y=\frac{5x+17*2}{8}\\y= \frac{5x+34}{8} \\8y=5x+34\\5x-8y+34=0[/tex]
So, The equation of required line is: [tex]\mathbf{5x-8y+34=0}[/tex]

What is the slope of the line that passes through the points (- 2, 8) and (- 22, 8) ? Write your answer in simplest form .
Answers
Answer:
0
Step-by-step explanation:
I love questions like these.
Ok so the formula for slope is
[tex]\frac{y2 - y1}{x2 - x1} [/tex]
In an ordered pair the first number is (x) and the second is (y). (x, y).
So that means y2 is the (y) of the second given pair and y1 is the y of the first given pair.
And x2 is the (x) of the second given pair, and the x1 is the (x) of the first given pair.
So now we fill in the formula.
[tex] \frac{8 - 8}{ - 22 - ( - 2)} [/tex]
simplify
[tex] \frac{0}{ - 20} [/tex]
0 divided by anything is still 0, so our slope is 0.
Well, to find slope of 2 points you need to use the point-slope formula: y2-y1/x2-x1. I attached a picture of my work so you can see what i'm talking about, but i'm going to explain what I did.
1. I labeled the coordinate pairs with x1, y1 and x2, y2. Since we know a coordinate pair looks like this (x,y), we take the first X and Y values and label them x1 and y1. Then, we take the second set of X and Y values and label them x2 and y2.
2. I plugged the numbers in where they belong in the formula. For example, when you label x1 should be -2. So on our formula, all we do is replace x1 with -2. Do that with all your numbers until the whole formula is filled in.
3. Then, solve it. You should get 0/-24 and you should always simplify your answer. However, in this situation, you cannot simplify. So, your answer is 0/-24.
Hope this helps :)

So I'm evaluating a newspaper articles claims.

Answers
Answer: The data appears to support the claim.
Explanation:
Ignore the year numbers.
Divide the two other values to get 2448/935 = 2.618
Round this to the nearest whole number to get 3
The data approximately supports the claim. It's not perfect, but it's fairly close.

Based on the binomial probability principle, the probability of passing the quiz if all answers are guessed [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Let :
Number of questions passed = kNumber of trials, n = 10Probability of success, p = 1/2 = 0.50q = 1 - p = 1 - 0.50 = 0.50Using the binomial probability relation :
[tex] P(x = x) = nCx \times p^{x} \times q^{n-x} [/tex] x = kSubstituting the values into the relation :
[tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Hence, the required probability expression is [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
