simplify the following expression: (x+7/4x) + (5/x-8) I also attached a photo of the problem if you get confused on how I typed it :)
Answer:
[tex] \frac{x^{2} + 19x - 56}{4 {x}^{2} - 32x} [/tex]
Step-by-step explanation:
Start by making the denominators of both fraction the same. This can be done by multiplying one fraction's denominator by the other.
After simplifying and combining the two fractions together, check if the numerator can be factorised such that there is a common factor in the denominator and numerator. In this case, the numerator cannot be factorised.
Lastly, expand the denominator.
[tex] \frac{x + 7}{4x} + \frac{5}{x - 8} [/tex]
[tex] = \frac{(x + 7)(x - 8)}{4x(x - 8)} + \frac{5(4x)}{4x(x - 8)} [/tex]
[tex] = \frac{x(x) + x( - 8) + 7(x) + 7( - 8) + 20x}{4x(x - 8)} [/tex]
[tex] = \frac{ {x}^{2} - 8x + 7x - 56 + 20x }{4x(x - 8)} [/tex]
[tex] = \frac{ {x}^{2} + 19x - 56}{4x(x - 8)} [/tex]
[tex] = \frac{ {x}^{2} + 19x - 56}{4 {x}^{2} - 32x} [/tex]

What is quotient and product rule of logarithm?Logarithm, the exponent or power to which a base must be raised to yield a given number. The quotient rule says that, the logarithm of a quotient is equal to a difference & the product rule says that logarithm of product is equal to the sum of logarithm.
here, we have,
given that,
2 In e^(ln 5x) = 2 In 15
now, we have to solve it for x.
we know that,
e^(ln 5x) = 5x
using the rule of logarithm.
so, we have,
2 In (5x) = 2 In 15
now, for solving,
comparing both sides, we get,
15 = 5x
i.e. x = 15/5
or, x = 3
Hence, The solution is, the value of x = 3.

Write an equation in point-slope form for the line through the given point with the given slope.
(–3, –7); m = -6/5
A. y – 7 = -6/5 (x-3)
B. y + 7 = -6/5 (x+3)
C. y + 3 = -6/5 (x+7)
D. y – 7 = -6/5 (x+3)
Answer:
B. y + 7 = -6/5 (x+3)
Step-by-step explanation:
Use the given slope and point to substitute into the point-slope formula y − y 1 = m ( x − x 1 ) .
Slope-intercept form: y = − 6 /5 x − 53 /5
Point-slope form: y + 7 = − 6 /5 ⋅ ( x + 3 )

Find the values of m and b for this line.
Answer:
b=-5, m= - 3/-2
Step-by-step explanation:
Slope equation is y=mx+b. Slope is finding the rise(vertical change) over run(horizontal change). In this case, -3 is our negative rise and 2 is our run. Put that into fraction form, we get negative 3/2. In the slope equation, b represents the y-intercept(where the line touches the y-axis). In this case, it is -5. Hope this helps you!

Answers:
Slope = undefined; y intercept = noneSlope = 2; y intercept = -2Slope = -1; y intercept = 1Slope = 0Slope = -4========================================================
Explanation:
1)
For any vertical line, the slope is always undefined. Recall that slope = rise/run. For a vertical line, the run is 0 because there is no left or right movement. This leads to a division by zero error. The vertical line is also parallel to the y axis, meaning that there isn't a y intercept whenever the line isn't directly on top of the y axis.
The equation of this vertical line is x = 3 as all points on this line have the same x coordinate of 3.
-----------------------
2)
We can use the slope formula for the points [tex](x_1,y_1) = (-1,-4) \ \text{ and } \ (x_2,y_2) = (3,4)[/tex]
So,
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{4-(-4)}{3-(-1)}\\\\m = \frac{4+4}{3+1}\\\\m = \frac{8}{4}\\\\m = 2\\\\[/tex]
The slope is 2.
The y intercept is -2 as this is the location where the diagonal line crosses the y axis.
The equation of this line is y = 2x-2.
-----------------------
3)
Same idea as problem 2.
[tex](x_1,y_1) = (-2,3)\\\\(x_2,y_2) = (3,-2)\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-2-3}{3-(-2)}\\\\m = \frac{-2-3}{3+2}\\\\m = \frac{-5}{5}\\\\m = -1\\\\[/tex]
The slope is -1.
The y intercept is 1 because the line cuts through 1 on the y axis.
The equation is y = -1x+1 which is the same as y = -x+1.
-----------------------
4)
Pick any two points from the table. Each column represents a different (x,y) ordered pair point. Those two points selected are then plugged into the slope formula. I'll pick the first two columns.
[tex](x_1,y_1) = (1,-2)\\\\(x_2,y_2) = (2,-2)\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-2-(-2)}{2-1}\\\\m = \frac{-2+2}{2-1}\\\\m = \frac{0}{1}\\\\m = 0\\\\[/tex]
Notice how the y coordinates are the same, which leads to a difference of 0 up top and ultimately the slope itself is also 0. We have a horizontal flat line here. All horizontal lines have a slope of 0.
The y intercept is -2 because all y values for this function are the same.
The equation is y = 0x-2 which is the same as y = -2.
-----------------------
5)
Again I'll pick the first two columns to plug into the slope formula, but you can pick any two columns you prefer.
[tex](x_1,y_1) = (-3,11)\\\\(x_2,y_2) = (-1,3)\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{3-11}{-1-(-3)}\\\\m = \frac{3-11}{-1+3}\\\\m = \frac{-8}{2}\\\\m = -4\\\\[/tex]
The slope is -4.
Use this slope value, along with any column from the table to form the (x,y) point, to plug into the slope intercept form below. I'll use the first column
y = mx+b
11 = -4*(-3)+b
11 = 12+b
11-12 = b
-1 = b
b = -1
The y intercept is -1.
The equation is y = -4x-1.

Find the width of a rectangle with an area of 13 3/4 square feet and a length of 5 1/2 ft
Answer:
2.6
Step-by-step explanation:
Could you mark this the brainlist
Answer:
2.5 or 2 1/2 ft is the width
Step-by-step explanation:
Area of rectangle = length × width
(13 3/4 can also be written as 13.75)
(5 1/2 can also be written as 5.5)
Area = l × w
13.75 = 5.5 × w
13.75 ÷ 5.5 = w
2.5 = w
What is the measure for x
Answer:
130 degrees
Step-by-step explanation:
A triangles angles have to equal 180 degrees
A right angle = 90 degrees
40+90=130
180-130=50
A straight angle has to equal 180 degrees
180-50=130
130 degrees
