Answer:
a = 8
Step-by-step explanation:
First find the equation of line using
y-y1=m(x-x1) --- m=slope = 7 and x1= -6 and y1= 1
y-1=7(x-(-6))
y-1=7x+42
y=7x+43
now let x be -5 to find y which is a
y=7(-5)+43
y=-35+43
y=8
so a = 8

2x-y =7
1x-y = 10
Answer:
(-3, -7)
Step-by-step explanation:
2x - y = 7 multiply by -1 ⇔ -2x + y = -7
1x - y = 10 Do not change ⇔ 1x - y = 10
-x = 3
x = -3
Use the second equation to solve on y when x = -3
-1x - y = 10
-1(-3) - y = 10
3 - y = 10
-y = 10 - 3
-y = 7
y = -7 Solution: (-3, -7)

With a headwind a plane traveled 128 km in 2h. The return trip with a tail wind took 24 min less. Find the air speed of the plane.
WILL GIVE BRAINLY TO FIRST ANSWER
Based on the information given, it can be noted that the air speed that the plane has will be 71.1 km per hour.
The number of hours used for the return trip will be:
= 2 hours - 24 minutes.
= 1 hour 36 minutes.
= 1.6 hours.
Therefore, the speed of the air plane will be:
= (128 + 128) / (2 + 1.6)
= 256/3.6.
= 71.1 km per hour.

I need the answers and explanation to a b c and d
Answer:
a) 4x -3y ≥ -24
b) 2x +3y ≥ -12
c) 4x -3y ≤ 12
d) 2x +3y ≤ 24
Step-by-step explanation:
All of the given points are on the axes, so it is useful to know the intercept form of the equation for a line is ...
x/a +y/b = 1 . . . . . . where a is the x-intercept and b is the y-intercept.
a)The boundary line for the first side is ...
x/-6 +y/8 = 1
4x -3y = -24 . . . . . . multiply by -24 to put in standard form
The graph shows the quadrilateral is to the right of this line, so its inequality is ...
4x -3y ≥ -24
__
b)The boundary line for side 2 has equation ...
x/-6 +y/-4 = 1
2x +3y = -12 . . . . . multiply by -12
The quadrilateral is to the right of this line, as well, so its inequality is ...
2x +3y ≥ -12
__
c)We can see from the graph that the x-intercept of the boundary line for side 3 is x=3. The equation for that boundary line is ...
x/3 +y/-4 = 1
4x -3y = 12
The quadrilateral is to the left of this line, so its inequality is ...
4x -3y ≤ 12
__
d)Apparently, side 4 is intended to use points already given. We assume it passes through (6, 4) and (0, 8). This boundary is parallel to side 2, so will have the same equation, but with a different constant.
2x +3y = 2(0) +3(8) = 24
The quadrilateral is to the left of this line, so its inequality is ...
2x +3y ≤ 24
__
The second attachment shows a graph of the four inequalities with their shading.
_____
Additional comment
All of the inequalities are written in standard form, so the x-coefficient is positive for all of them. The direction of the inequality symbol can be chosen to select values of x that are greater than or less than those on the boundary line. If the shading is to be to the right, then larger x-values are required, and the inequality will have the form ax + by ≥ c (a > 0). If shading is to the left, then smaller x-values are required, and the inequality symbol points in the other direction.

Kennedy made 12 3/8 cups of tea. She and her friends drank 7 1/4 cups. How much was left?
Answer: 5 1/8 cups
Step-by-step explanation:
Make 1/4 to 2/8 the. Subtract 3/8 by 2/8
1/4 = 2/8
3/8 - 2/8 = 1/8
Then subtract 12 and 7
12 - 7 = 5
Finally add 5 and 1/8
5 + 1/8 = 5 1/8 cups
The total cost of renting a beach

this situation?
Answer: 147 votes
Beacause they need to find out what to do with the beach house

What is a function?A function has an input and an output.
A function can be one-to-one or onto-one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Let the number of days the beach house is rented be represented by the variable "d".
If d is less than or equal to 7, then the total cost can be calculated as:
Total Cost = 375d + 100
If d is greater than 7, then the maximum cost would be reached by renting the house for 7 days and adding the $100 cleaning fee.
In this case, the total cost can be calculated as:
Total Cost = 375(7) + 100 = 2,675
Therefore,
The greatest value in the range for this situation is $2,675.

Convert 4 weeks to days.
O A. 28 days
O B. 29 days
O c. 31 days
O D. 30 days. I will mark brainiest hurry
There are 28 days in 4 weeks.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
There are 7 days in a week, so to convert weeks to days, we multiply the number of weeks by 7. For example, if we have 2 weeks, we would multiply 2 by 7 to get 14 days.
In this case, we are given 4 weeks and asked to convert it to days. So we multiply 4 by 7 to get:
4 x 7 = 28
Therefore, there are 28 days in 4 weeks.

a bag contains colored tils 3 tiles are red 6 tiles are green 3 tiles are blue a tile will be randomly selected from the bag what is the probabillities in decimal from that the tile selected will regreate
Answer:
By:Parrain
Step-by-step explanation:
The probability that the selected tile will be green is 0.5.
The probability that a tile will be green can be calculated by the formula:
= Number of green tiles / Total number of tiles
Total number of tiles is:
= 3 + 6 + 3
= 12 tiles
Probability of picking green tile is therefore:
= 6 / 12
= 50%
= 0.50
The probability of picking a green tile is 0.50

Find the area of the shape shown below.
Answer:
28 units.
Step-by-step explanation:
Area of square + Area of triangle + Area of rectangle = Area of figure shown
=> (4 x 4) + (1/2 x 4 x 2) + (2 x 4) = Area of figure shown
=> 16 + 4 + 8 = Area of figure shown
=> 28 = Area of figure shown
Therefore, the area of the figure is 28 units.
Hoped this helped.
Answer:
28 units.
Step-by-step explanation:
Act like the shape is just a normal rectangle, because thats easy to do. If it was a full rectangle the length would be 8 and the width would be 4. The formula for finding area of a rectangle is length times width so 8x4 is 32. Now, to find the actual area of the shape, you have to subtract a bit. (I'll add a picture to better explain what I am meaning) You imagine see a mini rectange in the corner with a length of 4 and a width of 2. The area for that is 8. But, only half of that imaginary rectangle is in the actual shape so subtract half of that shape (4) from the original 32 and you get 28. The area is 28 units.

(3, $2560) & (4, $512)
(3, $640) & (4, $512)
Question 6 (4 points)
Part B: Write an equation that can be used to find the value of the piano, v, after t years
Answer:
Part A would be: 3, $2560 & 4, 2048 I am pretty sure
Step-by-step explanation:
20% of 3,200 = 640
3,200-640= 2,560
then
20% of 2,560 = 512
2,560-512 = 2,048
hope this helps! :)
Part A: The first answer is correct, or (3, $2560) & (4, $2048)
Part B: V = 5,000(0.8)^t
5000 is the original price, 0.8 shows the value going down 20%, and t shows how many years.
