Identify an equation in point-slope form for the line perpendicular to y = x-7 that passes through (-2, -6).
A. y + 2 = -4(X+6)
B. V + 6 = -4(X+2) V
C. y +6 . ==1+2
D. 4-6-76-2
Answer:
[tex]y +6 = -(x +2)[/tex]
Step-by-step explanation:
Given
Perpendicular to: y = x - 7
Passes through (-2,-6)
Required
Find the equation
An equation has the form:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
In [tex]y = x - 7[/tex]
[tex]m = 1[/tex]
Since the required equation is perpendicular to [tex]y = x - 7[/tex], then the relationship between their slopes is:
[tex]m_2 = -\frac{1}{m}[/tex]
Substitute 1 for m
[tex]m_2 = -\frac{1}{1}[/tex]
[tex]m_2 = -1[/tex]
The equation is then calculated using:
[tex]y -y_1 = m(x - x_1)[/tex]
Where
[tex]m_2 = -1[/tex]
[tex](x_1,y_1) = (-2,-6)[/tex]
So, we have:
[tex]y - (-6) = -1(x - (-2))[/tex]
[tex]y +6 = -1(x +2)[/tex]
[tex]y +6 = -(x +2)[/tex]

A ball is thrown from a point 6 metres above the ground. The graph shows the height of the bake above the ground in metres. Estimate the speed of the ball in m/s after 1 second. You must show working.
Answer:
1.38
Step-by-step explanation:
1.7-0.4=1.8
1.8/1.3=1.38
On graph place point at (1,8) and draw a triangle
The speed of the ball is 2 m/s.
What is Speed?
The speed of the object is calculated as,
Speed = Distance / Time
Given that;
A ball is thrown from a point 6 meters above the ground.
The graph shows the height of the bake above the ground in meters.
Now,
Draw the line perpendicular to both the x - axis and y - axis for 0 to 1 second.
So, we get;
Value of y - coordinate = 2 m
Value of x - coordinate = 1 m
Thus, Speed of the ball = Distance / Time
= 2 / 1
= 2 m/s
So, The speed of the ball is 2 m/s.

In golf, the lower your score the better. Negative scores are best of all. Teri scored +1 on each of the first three holes at a nine-hole miniature golf course. Her goal is a total score of -9 or better after she has completed the final six holes. Let h represent the score Teri must avereage on each of the last six holes in order to meet her goal. Write a 2-step inequality you can use to find h
Answer:
h ≤ - 2
Step-by-step explanation:
Given :
Score on each of first 3 holes = +1
Total number of holes = 9
Target score - 9 or better ≤ - 9
Number of holes left = 9-3 = 6
h = average score on each of last 6 holes to meet target score ;
3 * (+1) + (number of holes left * average score) = target score
3 + (6 * h) ≤-9
3 + 6h ≤ - 9
6h ≤ - 9 - 3
6h ≤ - 12
h ≤ - 2

Find the independent variable and dependent and write an equation (gr 9 hw) 1) To fix a car, Fix-it Auto charges a base fee of $20 plus $40 per hour. 2) The cost of a banquet at Jean's Banquet Hall is $450 for the rental of the hall and $15 per guest. 3) An author earns a royalty of $1.25 for each book sold. 4) Marie has $500 in her bank account. Each week she plans to deposit $20.
Answer:
Step-by-step explanation:
Using the regression equation :
y = mx + c
y = dependent variable ; x = independent variable ; m = slope ; c = intercept
1.) base fee = $20 ; hourly charge = $40
Hourly charge = independent
Total charge = dependent
Total charge = 40x + 20
x = Number of hours
2.) rental fee = $450; charge per guest = $15
Total rental fee = dependent
Independent = $15 = charge per guest
Number of guest = x
Total fee = 15x + 450
3.)
Royalty earned = dependent variable
Cost per book = $1.25 = independent
Royalty earned = $1.25 * number of books
4.)
Amount deposited per week = $20 = independent variable
Amount in account = dependent variable
y = 500 + 20x
x = number of weeks
how do i do
x^2 - 7x - 34 = 10
^ = power to
can u answer this now please its urgent i only got 2 mars how do i get the other 2 marks and the bottom bit of the question got me 2 marks thew top bit didnt get me anything
Answer:
x = 11 / x = - 4
Step-by-step explanation:
x² - 7x - 34 = 10
x² - 7x - 34 - 10 = 10 - 10
x² - 7x - 44 = 0
x² + 4x - 11x - 44 = 0
x (x + 4) - 11 ( x + 4) = 0
(x - 11)(x + 4) = 0
(x - 11) = 0 / (x + 4) = 0
x = 11 / x = - 4

Step-by-step explanation:
When multiplying 2 numbers with the same base number, we can directly add their indices.
For example, 2¹ * 2³ = 2^(1 + 3) = 2⁴.
Therefore 7³ * 7^? = 7^(3 + ?) = 7¹⁴.
=> 3 + ? = 14, ? = 11.
The blank should be filled with 11.

The sum of two intergers is 9. Their difference is 5. What are the two intergers?
Answer: x + y = 9
x - y = 2
x = 5 + y
5 + y + y = 9
5 + 2y = 9
2y = 9 - 5
2y = 4
y = 2
----------
x = 9 - 2
x = 7

A recipe for 24 cookies calls for 4 tablespoons of sugar. If you make 40 cookies and use 5 tablespoons, will the cookies taste the same? Explain
Answer:
Step-by-step explanation:
No, because they wouldn't contain the same amount of sugar per cookie
for the first recipe - 24 cookies with 6 tablespoons
thats 6/24 so 0.25 tablespoons of sugar per cookie
for the second recipe - 36 cookies with 10 tablespoons
thats 10/36 so 0.276 tablespoons per cookie
the cookies in the second recipe would be slightly sweeter than the cookies in the first

Find the inequality
Answer:
y > x/2 + 2
Step-by-step explanation:
Firstly, we need the to find the equation of the line normally
the general form is;
y = mx + b
where m is slope and b is the y-intercept
From the graph, the y-intercept is 2
so we have the equation as;
y = mx + 2
We can find a point to substitute so as to get the slope;
we use the point (2,3)
3 = 2m + 2
2m = 3-2
2m = 1
m = 1/2
The equation of the line is;
y = x/2 + 2
Now, we can see we have a breaking line indicative of a non-equal to inequality
Also, the top is shaded meaning the points we need are above the line indicating a greater than
So, the inequality is;
y > x/2 + 2
Answer:
y > x/2 + 2
