Step-by-step explanation:
-7(2a – 1) -11
What is the answer?
Answer:
=−14a−4
Step-by-step explanation:
Let's simplify step-by-step.
−7(2a−1)−11
The equivalent value of the expression is A = -14a - 4
Given data ,
Let the equation be represented as A
Now , the value of A is
A = -7 ( 2a - 1 ) -11
On simplifying the equation , we get
A = -7 ( 2a - 1 ) -11
So , the left hand side of the equation is equated to the right hand side by the value of ( -7 ( 2a - 1 ) -11 )
Opening the parenthesis on both sides , we get
A = -7 ( 2a - 1 ) -11
From the distributive property , we get
A = -7 ( 2a ) + 7 ( 1 ) - 11
On further simplification , we get
A = -14a + 7 - 11
On combining the like terms , we get
A = -14a - 4
Therefore , the value of A = -14a - 4
Hence , the expression is A = -14a - 4

D' = (-4 + 4, -4 + 3) = (0, -1)The profit y (in dollars) for a business from selling x coats is represented by y=56x . Graph the equation.
Answer:
The graph of the equation is also attached.
From the graph, it is clear that at x = 0, the value of y = 0
Hence, the line passes through the origin with the y-intercept 0.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven that the profit y (in dollars) for a business from selling x coats is represented by the equation
[tex]y=56x[/tex]
comparing with the slope-intercept form of the line equation
m = 56
Determining the y-intercept
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
substitute x = 0 in the equation
y = 56(0)
y = 0
Thus, the y-intercept b = 1
Thus,
The equation y = 5x has:
The slope m = 56The y-intercept b = 1The graph of the equation is also attached.
From the graph, it is clear that at x = 0, the value of y = 0
Hence, the line passes through the origin with the y-intercept 0.

Answer:
5) (x, y) = (10, -1)
6) (x, y) = (5, 6)
Step-by-step explanation:
5) y coefficients are opposites, so y can be eliminated by adding the two equations.
(x -y) +(2x +y) = (11) +(19)
3x = 30 . . . . . simplify
x = 10 . . . . . . . divide by 3
Using the second equation, we can find y:
2(10) +y = 19
y = -1 . . . . . subtract 20
The solution is (x, y) = (10, -1).
__
6) The x-coefficients are the same, so we can eliminate the x-term by subtracting the second equation from the first. We choose to do it that way so the y-coefficient ends up positive.
(-6x +6y) -(-6x +3y) = (6) -(-12)
3y = 18 . . . . . . simplify
y = 6 . . . . . . . . divide by 6
Using the first equation to find x, we have ...
-6x +6(6) = 6
x -6 = -1 . . . . . . . divide by -6
x = 5 . . . . . . . . . add 6
The solution is (x, y) = (5, 6).

the length of a line segment is 8 units.one end point is p(5,-3). which of these could be the other endpoint

Option A is the correct answer.
What is the distance between two points of a line?
The distance between two points of a line is given as:
Distance = [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
Where (a, b) and (c, d) are the two endpoints.
We have,
Distance between the points = 8 units
One endpoint = (5, -3) = (a, b)
Another endpoint = (c, d)
Now,
Substituting the values.
Distance = [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]
Now,
We have to check each point.
(-3,-3) = (c, d)
8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]
8 = [tex]\sqrt{(-3 - 5)^2 + (-3 + 3)^2}[/tex]
8 = [tex]\sqrt{(-8)^2[/tex]
8 = √64
8 = 8
This is true
(-3,-11) = (c, d)
8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]
8 = [tex]\sqrt{(-3 - 5)^2 + (-11 + 3)^2}[/tex]
This is not true.
(5,8) = (c, d)
8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]
8 = [tex]\sqrt{(5 - 5)^2 + (8 + 3)^2}[/tex]
This is not true.
(8,-3) = (c, d)
8 = [tex]\sqrt{(c - 5)^2 + (d + 3)^2}[/tex]
8 = [tex]\sqrt{(8 - 5)^2 + (-3 + 3)^2}[/tex]
This is not true.
Thus,
(-3,-3) is the other endpoint.

4.Kusum bought 80 cookers at R5.700 EACH: Transport cost her Rs.1280.Ifshe wants a profit of
Rs.18000, What should be the selling price per cooker?
Answer:
The selling price of each is Rs.5941
Step-by-step explanation:
Given
[tex]N = 80[/tex] ---- Cookers
[tex]CP = Rs. 5700[/tex] --- Cost Price
[tex]Transport = Rs.1280[/tex]
[tex]Profit = Rs.18000[/tex]
Required
Determine the selling price (SP) of each
First, calculate the total cost price:
[tex]Total = N * CP + Transport[/tex]
[tex]Total = 80 * 5700 + 1280[/tex]
[tex]Total = 457280[/tex]
Selling Price is calculated using:
[tex]Selling\ Price = Cost\ Price + Profit[/tex]
[tex]Selling\ Price = 457280 + 18000[/tex]
[tex]Selling\ Price = 475280[/tex]
So, the total selling price of the 80 cookers is: Rs.475280
The selling price of each is:
[tex]Each = \frac{475280}{80}[/tex]
[tex]Each = 5941[/tex]
The selling price of each is Rs.5941

In a right triangle, the leg adjacent to an angle of 23° is 12 cm long. How long is the leg opposite the 23° angle, to the nearest tenth?
Answer:
tan55 = x/43
x = tan(55) * 43
x = 61.4 cm
Step-by-step explanation:
The length of the leg opposite the 23° angle, to the nearest tenth, will be 5.1 cm.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
In a right triangle, the leg adjacent to an angle of 23° is 12 cm long. The triangle is given below.
Let 'x' be the opposite side of the angle 23°. Then the value of the variable 'x' is given as,
tan 23° = x / 12
Simplify the equation, then we have
tan 23° = x / 12
0.4244 = x / 12
x = 0.4244 · 12
x = 5.1 cm
The length of the leg opposite the 23° angle, to the nearest tenth, will be 5.1 cm.
