Given m n, find the value of x and y.
The value of x and y from the given parallel lines are 140° and 40° respectively.
Given that, straight line m parallel to straight line n and t is the transversal.
Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.
Here, y°+140°=180° (Adjacent angles on straight line)
y°=40°
y°+z°=180° (Allied angles adds upto 180°)
40°+z°=180°
z°=140°
Now, x=140° (Vertically opposite angles are equal)
Therefore, the value of x and y from the given parallel lines are 140° and 40° respectively.

Step-by-step explanation:
The way we divide fractions like this is to take the inverse of the divisor (second fraction) and multiply. So 1/6 x 4/1 = 4/6 which reduces to 2/3.
Is this true? log(x) = logb(c) * log(x). For this question, first try several examples. Then prove it. See the proofs in the Basic Math lecture for ideas. (Hint: let
m = logb(x) and n=logb(c) and p = logc(x). Then use the definition of logarithms and rules of exponents to show m = np.
The logarithmic statement [tex]log_bx=log_bc \cdot log_cx[/tex] is true.
Logarithm is a mathematical operator that is used to simplify the exponential equations .
The logarithm is exponentiation's opposite function in mathematics. This indicates that the base b of another fixed number, the logarithm of a given number x, is the exponent that must be raised in order to obtain the given number x.
The exponential equation logₓy=n is equivalent to xⁿ=y.
The properties of Logarithmic equations are:
log x + log y = log xylog x-log y= log (x/y)log ₙn=1n log x = log xⁿ[tex]log_ab=\frac{log_xa}{log_xb}[/tex] , x≠0Now the given expression is of the form: [tex]log_bx=log_bc \cdot log_cx[/tex]
We know that [tex]log_bc=\frac{log_nc}{log_nb}[/tex] and [tex]log_cx=\frac{log_cx}{log_nc}[/tex]
let n=[tex]log_bc=\frac{log_nc}{log_nb}[/tex] and p=[tex]log_cx=\frac{log_cx}{log_nc}[/tex]
Now for the right side of the equation we have:
n×p
[tex]log_bc \cdot log_cx[/tex]
This can be written as:
[tex]or, \frac{log_nc}{log_nb}\cdot\frac{log_cx}{log_nc}\\or, \frac{log_cx}{log_nb}\\or, log_bx[/tex]
which is equivalent to the left side of the equation.
Hence the statement [tex]log_bx=log_bc \cdot log_cx[/tex] is true.

Step-by-step explanation:
(x + 4)(x − 12) = 0 can someone help me with this
Answer:
You chose the correct option on the picture
x = -4; x = 12
Step-by-step explanation:
You solve for x by simplifying both sides of the equation, then isolating the variable.
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x + 4 = 0
x − 12 = 0
Set x + 4 equal to 0 and solve for x.
Set x+4 equal to 0.
x+4=0
Subtract 4 from both sides of the equation.
x = −4
Set x − 12 equal to 0 and solve for x.
Set x−12 equal to 0.
x−12=0
Add 12 to both sides of the equation.
x=12
The final solution is all the values that make (x+4)(x−12)=0 true.
x=−4,12

plz give brainlyest
It is found that in Step IV; Tommy must set the quadratic equations equal to 0 before factoring and then solving.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Given that the system of a linear equation and a quadratic equation.
2x – y = –1
x² – 5x – y = –7
Now Tommy had completed the following steps in his algebraic solution process but could not factor the resulting quadratic equation as;
x² – 7x – 1,
Step I: y = 2x + 1
Step II: x² – 5x – (2x + 1) = –7
Step III: x² – 5x – 2x – 1 = –7
Step IV: x² – 7x – 1 = –7

Answer:
(ii) center: (-3, 6)
(iii) A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)
(iv) (x +3)²/100 +(y -6)²/51 = 1
Step-by-step explanation:
(ii) The center is the midpoint between the foci:
center = ((-10, 6) +(4, 6))/2 = (-10+4, 6+6)/2
center = (-3, 6)
__
(iii) The vertices are the center plus or minus the semi-major axis length in the x-direction: (-3±10, 6).
The semi-minor axis length is the root of the difference of squares of the semi-major axis and the center-focus distance:
semi-minor axis = √(10² -7²)
semi-minor axis = √51
So, the co-vertices are the center plus or minus this value in the y-direction: (-3, 6±√51)
Using the labeling in the drawing the various points are ...
A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)
__
(iv) For center (h, k) and semi-axis lengths 'a' and 'b' the equation of an ellipse is ...
(x -h)²/a² +(y -k)²/b² = 1
For the center and axes here, the equation is ...
(x +3)²/100 +(y -6)²/51 = 1

A florist has to pay $7.50 each time a customer chooses a competitor for the delivery of flowers. Which expression shows the amount that the florist earns if p people use a competitor for delivery, and the company makes $320.00 before any payment is made to their competitors?
320 minus 7.50 p
320 + 7.50 p
7.50 p minus 320
7.50 p + 320
Answer:
320 minus 7.50 p
Explanation:
the florist earned 320 dollars and then lost money due to having a competitor deliver, since we dont know the amount of people who chose competitors we use the term p next to the amount that p is worth because each time a customer uses a competitor it costs 7.50 out of the original 320.

what is the discriminant of the polynomial below 4x^2 +4x + 1
The value of the discriminant of the given quadratic equation is 0.
What is a Discriminant?The part in the formula of a quadratic equation that helps us to know the nature of the roots of a quadratic equation is known as a discriminant.
D = b² - 4ac,
If the value of the discriminant is greater than zero then the roots of the equation are real and distinct,If the value of the discriminant is equal to zero then the roots of the equation are real and same, andIf the value of the discriminant is less than zero then the roots of the equation are imaginary.Given the quadratic equation 4x² +4x + 1, if this equation is compared with the general quadratic equation. Then the value of the variables can be written as,
a = 4
b = 4
c = 1
Now, the value of the discriminant of the equation can be written as,
D = b² - 4ac
= (4)² - 4(4)(1)
= 16 - 16
= 0
Hence, the value of the discriminant of the given quadratic equation is 0.
