ILL GIVE YOU BRAINIEST
Answers
Answer:
Option (B)
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line which passes through the points (1, 1) and (-4, 7) will be,
m = [tex]\frac{7-1}{-4-1}[/tex]
= [tex]-\frac{6}{5}[/tex]
By substituting the value of m in the equation,
y = [tex]-\frac{6}{5}x+b[/tex]
Since, this line passes through (1, 1),
1 = [tex]-\frac{6}{5}(1)+b[/tex]
b = [tex]1+\frac{6}{5}[/tex]
= [tex]\frac{11}{5}[/tex]
Therefore, equation will be,
[tex]y=-\frac{6}{5}x+\frac{11}{5}[/tex]
5y = -6x + 11
6x + 5y = 11

What is the gravitational PE of the same 61.2 kg person standing on the 6th floor (Each story is 2.5 m high)?
Answers
Answer: U is the change in PE, m is the mass raised through a distance h. So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

Answer:
y=3/2x-8
Step-by-step explanation:
Step 1: Begin by distributing the 3/2 to the parentheses. This would result with 3/2x-6.
Step 2: Subtract both sides by 2 to isolate the variable, y. This would result with y=3/2x-8.

WRITE YOUR ANSWER AS A DECIMAL AND ROUND TO THE NEAREST TENTH (1 decimal place)
Answers
Answer:
I don't think it's possible for this to be a decimal because the slope is positive 11.
Step-by-step explanation:
Use slope formula. x2-x1/y2-y1. Since we always go with the smaller x value we do 8-(-3) / 4-3/ We'll get 11 for 8-(-3) and we'll get 1 for 4-3/ so that leaves us with 11/1 which can't be simplified and has no decimal.

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)
Step-by-step explanation:
1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b
2. A proportional relationship has a constant rate of change.
ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.
3. A proportional relationship must pass through the origin in order to be a proportional relationship.
4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.
5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.

Find the x and y intercept of the line below
2x + 5y = 10
Answers
Answer:
x - intercept = 5
y- intercept = 2
Step-by-step explanation:
2x + 5y = 10
Write the equation in [tex]\frac{x}{a}+\frac{y}{b}=1[/tex] form
So, divide the equation by 10
[tex]\frac{2x}{10}+\frac{5y}{10}=\frac{10}{10}\\\\\frac{x}{5}+\frac{y}{2}=1[/tex]
x - intercept = 5
y- intercept = 2
Answer:
(5,0) and (0,2)
Step-by-step explanation:
Basically, all we need to do is enter 0 for both variables. We can do this because the y-value of an x-intercept will always be 0, and the x-value of a y-intercept will always be 0.
So, to find the x-intercept we can set y equal to 0 and then solve for x.
[tex]2x+5(0)=10\\2x=10\\x=5[/tex]
So the x-intercept will be (5,0).
We can do the same thing to find the y-intercept.
[tex]2(0)+5y=10\\5y=10\\y=2[/tex]
The y-intercept is (0,2)

Jacob started a savings account with a 1% annual simple interest rate. His principal deposit was $147. He saved the money for 6 years. How much interest did he earn after 6 years?
Answers
Answer:
The interest Jacob earns after 6 years is $8.82
Step-by-step explanation:
The given parameters are;
The simple interest rate of the savings account, R = 1%
The principal deposit to the savings account, P = $147
The time duration Jacob saved the money, T = 6 years
The formula for simple interest, I, is given as follows;
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
Substituting the known values gives;
[tex]I = \dfrac{147 \times 1 \times 6}{100} = 8.82[/tex]
The interest Jacob earns after 6 years = $8.82.

Subtract the depth of the water from the height of the tank (0.6) and use this measurement for height instead. then calculate l•h•2+w•h•2+l•w
(we multiplied the length and height and the width and height by two since there’s two sides with the same measurement for each)

An architect is trying different dimensions for the room shown below. Write an algebraic expression the architect can use to find the area of the room then find the area when x is 6 m. Show your work.
Answers
Answer:
x² + 12
48m²
Step-by-step explanation:
Find the diagram attached.
The room can be segregated into two rectangles
The area of the room = Area of bottom rectangle + area of the top rectangle
Area of the bottom rectangle = x * (x-3) = x² - 3x
Area of the top rectangle = 3* (4+x) = 12 + 3x
The area of the room = x² - 3x + 12 + 3x
Area of the room = x² + 12
Hence the algebraic expression that the architect can use to find the area of the room is x² + 12
Given x = 6m
The area of the room = x² + 12
The area of the room = 6² + 12
The area of the room = 36 + 12
The area of the room = 48m²
Kimoni wants to purchase a pair of shoes that are on sale for 10% off the regular price
of $64.00. Which is the sale price of the shoes?
Answers
64 - 6.4 = $57.60
Answer:
the price of the pair of shoes are $57.60
Step-by-step explanation:
So you first need to find out what 10% is in $64 so your going to multiply 0.1 (10% in decimal form is 0.1 ) by 64 to get 10% of the original price.
64 * 0.1 = $6.40
so now we are going to subtract $6.40 from $64 for the sale price:
$64.00 - $6.40 = $57.60
so the sale price is $57.60
