Which equation represents a line which is parallel to the line
6x + 7y = –49?
Answer: y= 7/6x-5
Step-by-step explanation:
The equations of parallel lines have the same slope or rates.
The equation of the line parallel to [tex]\mathbf{6x + 7y = -49}[/tex] is [tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]
The equation is given as:
[tex]\mathbf{6x + 7y = -49}[/tex]
Make 7y the subject
[tex]\mathbf{7y = -6x-49}[/tex]
Make y the subject
[tex]\mathbf{y = -\frac{6}{7}x -7}[/tex]
A linear equation is represented as:
[tex]\mathbf{y =mx + b}[/tex]
Where m represents the slope.
So, we have:
[tex]\mathbf{m = -\frac 67}[/tex]
Parallel lines have the same slope.
So, the slope of the line is [tex]\mathbf{m = -\frac 67}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
Substitute [tex]\mathbf{m = -\frac 67}[/tex]
[tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]
Hence, the equation of the line parallel to [tex]\mathbf{6x + 7y = -49}[/tex] is [tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]

how do you know how many solutions are possible for a system of equations
Answer:
Step-by-step explanation:
If the slopes are the same but the y-intercepts are different, the system has no solution.
If the slopes are different, the system has one solution.
If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
Answer:
Step-by-step explanation:
If you mean linear systems. If lines have a different slope there will be one solution. If they have the same slope (parallel) and a different y intercept there are zero solutions. If they have same slope and y intercept than they are the same line and have an infinite number of solutions.

Answer:
x = -0.441 and x = -2.359
Step-by-step explanation:
The given equation is :
[tex]2(5x+7)^2-13=33[/tex]
Adding 13 to both sides of the equation.
[tex]2(5x+7)^2-13+13=33+13\\\\2(5x+7)^2=46\\\\(5x+7)^2=23[/tex]
So,
[tex]5x+7=\sqrt{23}\\\\5x+7=\pm4.795\\\\5x=4.795-7, 5x=-4.795-7\\\\5x=-2.205, 5x = -11.795\\\\x=-0.441, x=-2.359[/tex]
So, the solution of the given equation is x = -0.441 and x = -2.359.

How do I graph
y=-1/2x-1
Answer:
Step-by-step explanation:
Find the x and y intercept, and determine the slope.
X-intercept:
[tex]0=-\frac{1}{2}x-1\\1=-\frac{1}{2}x\\x=-2[/tex]
It crosses the x-axis at x = -2
Y-intercept:
[tex]y=-\frac{1}{2}(0)-1\\y=-1[/tex]
It crosses the y-axis at y = -1
Slope:
y = mx + b
m = slope = -1/2
The graph of the linear equation y = -(1/2)x - 1 is plotted.
Given data:
To graph the equation y = -1/2x - 1, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
So, the slope is -1/2, and the y-intercept is -1.
To plot the graph, follow these steps:
Plot the y-intercept:
Start by plotting the point (0, -1), which represents the y-intercept.
Use the slope to find another point: Since the slope is -1/2, use the rise and run method. From the y-intercept point (0, -1), move down 1 unit (negative 1) and then move to the right 2 units. This gives another point on the line, which is (2, -2).
Hence, the resulting graph should be a straight line sloping downwards from left to right and is plotted below.

£2,300 is invested for 4 years at 5% per year simple interest work out the total interest
Answer:
£460
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2300 × 0.05 × 4 = 460
I = £ 460.00
The simple interest accumulated
on a principal of £ 2,300.00
at a rate of 5% per year
for 4 years is £ 460.00.
