Step-by-step explanation: got it right on edg.
The solution to the given system of equations is (2, 3). Therefore, option B is the correct answer.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Given that, the system of equations are y=-1/2x+4 -------(I) and y=2x-1 -------(II)
Now, solution is
2x-1=-1/2x+4
2x+1/2x=4+1
5x/2=5
5x=10
x=2
Substitute x=2 in equation (II), we get
y=2(2)-1
y=3
So, solution is (2, 3)
The solution to the given system of equations is (2, 3). Therefore, option B is the correct answer.

Answer: See explanation
Step-by-step explanation:
To solve this, we have to calculate the lowest common multiple of 2 and 5. This will be:
Multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 ....
Multiples of 5 = 5, 10, 15, 20 ....
This means that he will swim and bike every 10th day together. This will be on the 10th, and 20th in October.

Given:
The set of ordered pairs in the options:
(a) (2, 3), (2, 2), (2, 4), (2, 9), (2, –2)
(b) (1, 5), (2, 6), (1, 6), (4, 5), (1, 4)

(d) (5, 1), (7, 3), (9, 5), (11, 7), (13, 9)
To find:
The set of ordered pairs that could represent a function.
Solution:
A set of ordered pairs represent a function, if there exist unique output (y-value) for each input (x-value).
In option (a) we have, five output values y=3,2,4,9,-2 for single input x=2. So, it is not a function.
In option (b) we have, three output values y=5,6,4 for single input x=1. So, it is not a function.
In option (c) we have, two output values y=0,3 for single input x=1. So, it is not a function.
In option (d), all inputs has unique output.
Therefore, the correct option is (d).

1. The product of 4, and a number decreased by 7, .is 100. Find the number
Answer:
32
Step-by-step explanation:
As per what is given
- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)
- equals 100, the equation formed equals 100
Form an equation;
4(x - 7) = 100
Solve using inverse operations;
4(x - 7) = 100
/4 /4
x - 7 = 25
+7 +7
x = 32

Answer:
y=-3x+2
Step-by-step explanation:
Slope-intercept form is given by the equation y=mx+b, where m is defined as the slope and b is defined as the y-intercept (the value on the y-axis that the line crosses). First we can determine the slope by using the slope formula.
m=(y2-y1)/(x2-x1), given two points (x1, y1) and (x2, y2). Keep in mind you can choose which point is (x1,y1) and which is (x2,y2) as long as you are consistent.
Plugging in for (-1,5) and (1,-1), you will get:
m=(-1-5)/(1-(-1))=-6/2=-3
Next, we need to find the y-intercept. For this problem, you can determine it is 2 by looking at the graph of the line. We now have both components to create the slope-intercept form.
m=-3, b=2
y=-3x+2

The slope of the line that passes through the points (5, 10) and (2, 12) is?
Answer:
[tex]\boxed{\sf m=-\cfrac{2}{3}}[/tex]
Step-by-step explanation:
In order to fins the slope we can either use the slope formula m = (y_2-y1)/(x2 – x1) or the standard line equation, y = mx + b to solve for the slope, m.
Using two points on the line, we can find the slope by finding the rise and the run
Slope formula :-
[tex]\boxed{\sf m=\cfrac{rise}{run} =\cfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf \left(x_1,\:y_1\right):\left(5,\:10\right)[/tex]
[tex]\sf \left(x_2,\:y_2\right):\left(2,\:12\right)[/tex]
[tex]\sf m=\cfrac{12-10}{2-5}[/tex]

Oy-9=-3/7(x-4)
Oy-9= 3/7(x-4)
Oy- 9= -3/7(x+4)
Oy- 9= -3/7(x+4)
Answer:
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
Step-by-step explanation:
Slopes are negative reciprocals when two lines are perpendicular
[tex]m= - \frac {3}{7}[/tex]
Equation of straight line in point-slope form is given as
[tex]y-y_1=m(x-x_2)[/tex]
Here [tex](x_1, y_1)= (-4, 9)[/tex]
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (-4, 9).
And, The perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
Now,
Since, The equation of line passes through the point (- 4, 9).
So, We need to find the slope of the line.
Since, The product of the slope of perpendicular line is - 1.
Hence, Slope of the perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
m = dy/dx = 7/3
m = 7/3
Thus, The equation of line with slope - 3/7 is,
⇒ y - 9 = - 3/7 (x - (-4))
⇒ y - 9 = - 3/7 (x + 4)
⇒ y - 9 = - 3/7x - 12/7
⇒ y = - 3/7x + 9 - 12/7
⇒ y = - 3/7x + 51/7
Therefore, The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7
