Answer:
Y = -3/4 + 7
Step-by-step explanation:
7 is the y intercept
-3/4 is the slope
“Write a linear equation that is perpendicular to 2x-5y=5 and passes through the point (2,-9).
So first I made it into the Slope Intercept Form which would be -5y=-2x+5, then I divided everything by -5 (from the -5y) and got y=2/5-1.
After that I realized it was perpendicular (and this is where I got confused) I switched it to y=-5/2-1. (yeah I think it’s wrong)
Then I put it in the Point slope formula making it to be y-(-9)=-5/2(x-2). So that would be y+9=(-5/2)x+5.
So the product after doing the -9 from each side, would it be y=(-5/2)x-4?
The correct equation of the line that is perpendicular to 2x - 5y = 5 and passes through the point (2, -9) is y = (-5/2)x - 4.
Here,
Let's go through the steps again and find the correct equation for the line that is perpendicular to 2x - 5y = 5 and passes through the point (2, -9).
Step 1: Convert the given equation into slope-intercept form.
2x - 5y = 5
Subtract 2x from both sides:
-5y = -2x + 5
Now, divide everything by -5 to isolate y:
y = (2/5)x - 1
So, the slope of the given line is 2/5.
Step 2: Find the slope of the line perpendicular to the given line.
For two lines to be perpendicular, their slopes must be negative reciprocals of each other.
The negative reciprocal of 2/5 is -5/2.
Step 3: Write the equation of the line using the point-slope form.
Now that we have the slope (-5/2) and a point (2, -9), we can use the point-slope form of the linear equation:
[tex]y - y_1 = m(x - x_1)[/tex]
where m is the slope, and [tex](x_1, y_1)[/tex]is the given point.
Substitute m = -5/2 and [tex](x_1, y_1)[/tex] = (2, -9):
y - (-9) = (-5/2)(x - 2)
Simplify:
y + 9 = (-5/2)x + 5
Now, isolate y by subtracting 9 from both sides:
y = (-5/2)x + 5 - 9
y = (-5/2)x - 4
So, the correct equation of the line that is perpendicular to 2x - 5y = 5 and passes through the point (2, -9) is y = (-5/2)x - 4.

need help w math question
Answer:
y = P • (1+r)^t
Balance after 2 years: $3307.5
Step-by-step explanation:
To answer this question, we will use standard equation that calculates bank interests:
A = P(1+(r/n))^(n•t)
It might seem complicated, but let's explain:
A - amount of money after the time period
P - principal amount, the amount of money you started with
r - interest rate, in decimal numbers
n - number of times interest is being calculated per year
t - number of years
Since here, interest is annual, n = 1, so our equation is:
A = P(1+r)^t
P = $3000
r = 5% = 0.05
t = 2 years
A = 3000(1+0.05)^2
A = 3000•(1.05)^2
A = $3307.5
Which product is the better deal 60 oz for $7.20 or 75 oz for $8.25
The better deal
Would be the lowest cost per ounce.
Divide total cost by total ounces and compare them.
7.20/60 = 0.12 per ounce.
8.25/75 = 0.11 per ounce.
75 ounces for 8.25 is the better deal
divide 40 into the ratio 9:1
Answer:
36 : 4
Step-by-step explanation:
40 divided into ratio 9:1 is like 40 / (9 + 1) multiplied to both sides of 9:1
40 / (9 + 1) = 4, and if you multiply both sides by 4, you get 36 : 4
Answer:
I think the answer is 36
Step-by-step explanation:
You add 9 and 1 to get 10 and then you divide 40 by 10 and get 4 and then you multiple 9 and 4 to get 36.
Find the 43rd term of each sequence 27,24,21,18, ...
Answer:
hmmmmmmmmmm thats a tuff one
Answer:
-99
Step-by-step explanation:
First, let's find an equation to use to make things easier.
So, as we can see, the numbers go down 3 every time and we start at 27, so, the first term is 27, that means that we need to find the number before 27, so we add 3 to 27 to get 30.
We can put the equation using y = mx + b, since that is the most appropriate formula to use.
y = -3x + 30
y = -3(1) + 30
y = -3 + 30
y = 27
y = -3x + 30
y = -3(2) + 30
y = -6 + 30
y = 24
So, this is a good equation to use. Now, we substitute 43 as x
y = -3x + 30
y = -3(43) + 30
y = -129 + 30
y = -99

Answer: Angle X
Reason: For any triangle, the largest angle is always opposite the longest side.
∠X is the largest measure on the triangle XYZ.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The angle opposite to the largest side is the largest measure.
So,
XY = 6 and opposite angle = ∠Z
YZ = 9 and opposite angle = ∠X
XZ = 8 and opposite angle = ∠Y
We see that,
YZ > XZ > XY
So,
∠X > ∠Y > ∠Z
Thus,
∠X is the largest measure on the triangle XYZ.

A set of biology exam scores are normally distributed with a mean of 707070 points and a standard deviation of 666 points. Let XXX represent the score on a randomly selected exam from this set. Find P(64
Answer:
[tex]P(64<x<76)=0.68[/tex]
Step-by-step explanation:
Given that, the mean, [tex]\mu[/tex], and the standard deviation, [tex]\sigma[/tex], of normally distributed exam score are :
[tex]\mu=70[/tex]
[tex]\sigma=6[/tex]
Let [tex]x[/tex] represent the score on a randomly selected exam from this set
The z-score, for the randomly selected exam score x:
For 64<x<76, the range of z-score is
[tex]\frac{64-70}{6}<z<\frac{76-70}{6}= -1<z<1[/tex]
Now, from the z-score table, the value for z=-1 is the probability for x<64.
As the value for z=-1 is 0.15866, so
P(x<64)=0.15866.
Similarly, the value for z=0.67 is 0.84134, so
P(x<76)=0.84134
So, [tex]P(64<x<76)= P(x<76)-P(x<64) \\\\[/tex]
[tex]\Rightarrow P(64<x<76)=0.84134-0.15866=0.68268.[/tex]

Bobby has 36 toy cars with stickers on them. Each car has 2 red stickers and one blue sticker. Which expression represents the total number of stickers on the 36 cars?
Given:
Total number of cars = 36
Each car has 2 red stickers and one blue sticker.
To find:
The expression that represents the total number of stickers on the 36 cars.
Solution:
Total number of cars = 36
Each car has 2 red stickers and one blue sticker. So,
Total number of stickers on each car = (2+1)
Total number of stickers on 36 car = 36(2+1)
= 36(3)
= 108
Therefore, the required expression for the total number of stickers on the 36 cars is 36(2+1) and the total number of stickers is 108.
