a) [tex]-30+48x[/tex]
Step-by-step explanation:
To find an expression equivalent to [tex]-6(5-8x)[/tex], we can expand the brackets.
[tex]-6(5-8x) = -6(5) - 6(-8x)\\\\[/tex]
[tex]=-30+48x[/tex]
[tex]\therefore -6(5-8x)=-30+48x[/tex] , option a.

The graph of the equation y = 8x - 6 is a straight line.
What is slope intercept form?The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept
(0, b).
Given is an equation, y = 8x - 6
Finding the coordinates,
Put x = 0, y = -6
(0, -6)
Put y = 0
8x = 6
x = 0.75
(0.75, 0)
Plotting the graph,
Hence, we will get a straight line of the graph.

A line has a slope of 3 and passes through the point (4, 7). What is its equation in
slope-intercept form?
Answer:
Step-by-step explanation:
y - 7 = 3(x - 4)
y - 7 = 3x - 12
y = 3x - 5
The equation of the line in slope intercept form having slope 3 and passing through the point (4, 7) is y = 3x - 5.
What is Slope?Slope of a line is the rise over the run of the given line. It is usually denoted by m.
In other words, Slope of a line can be calculated by finding the difference of the y coordinates divided by the difference of the x coordinates where x coordinate and y coordinate of two points are given.
Equation of a line in slope intercept form is given by
y = mx + c
where, m is the slope and c is the y- intercept.
Now y-intercept is the y-coordinate of the point where x = 0 or when the line touches the Y axis.
Here, m = 3
We have a point (x, y) = (4, 7)
Substituting these values in the equation,
7 = (3 × 4) + c
7 = 12 + c
c = 7 - 12
c = -5
Substituting m = 3 and c = -5,
y = 3x - 5
Hence, the equation of the line passing through the point (4, 7) and with a slope of 3 is y = 3x - 5.

Find the 52nd term of the arithmetic sequence 5, 9, 13
Answer:
209
Step-by-step explanation:
You would first create an explicit formula for the provided sequence.
The basic explicit formula for arithmetic sequences is [tex]a_{n} = d(n-1) + a_{1}[/tex], where an is the number of the term, d is the number you are adding or subtracting by, n the location of the term, and a1 is the first number.
We would then substitute the values given into the formula.
We are trying to solve the value of the 52nd term. This makes n = 52. The first number of the sequence is 5, so a1 is 5. Finally, d is 4 because we are adding 4 to each number in the sequence.
Therefore, our resulting equation would be [tex]a_{n} =4(52-1)+5[/tex], which equals 209.

The account must pay a 40 percent interest rate under Marcos.
A basic interest account is what?A loan's or deposit's initial principal serves as the foundation for simple interest.
Contrarily, compound interest is calculated based on both the principal amount and the interest that is accrued on it each period.
Simple interest is simpler to compute than compound interest because it is just applied to the principal.
