Answer:
1/10
Step-by-step explanation:
your equation is 4/5 divided by 8/1.
Lets solve that problem with the acronym KCF, or
Keep
Change
Flip.
K: "keep" the first fraction, or the one you are multiplying with, so 4/5 stays the same.
C: "change" the division sign to a multiplication sign, so 4/5x8/1
F: "flip" the second fraction, so 8/1 becomes 1/8.
now our equation is 4/5x1/8. If we solve that, we get 4/40, which reduced is 1/10.
Choose the equation that represents the line passing through the point (−2, −3) with a slope of −6.
y = −6x − 15
y = −6x − 20
y = −6x + 15
y = −6x + 20
Answer:
[tex]y = mx + c \\ - 3 = - 2( - 6) + c \\ c = - 15 \\ y = - 6x - 15[/tex]

please help me
Answer:
you betrayed me and i know that youll never feel srry
Step-by-step explanation:
What is the slope of a line which passes through points (-7,2) and (21,-10)?
The question gives us two points, (-7,2) and (21,-10), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (2 - (- 10)) ÷ (-7 - 21)
= - ¹²/₂₈
= - ³/₇
Checking my answer:
We can use the slope we found and a point to write the equation of a line. If the line passes through both points, then we calculated the slope correctly.
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y + 10 = - ³/₇ (x - 21)

Which table represents a linear function?
Answer:
it should be D
Step-by-step explanation:
Which two functions always Which two functions always share the domain (-∞, ∞) and range (-∞, ∞)?
linear
absolute value
quadratic
exponential
reciprocal
cubic
cube root
square root
Answer:
Linear.
Cubic.
Step-by-step explanation:
Two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.
What is domain?" Domain is defined as the set of all input values in the given function."
What is range?" Range is defined as the set of all output values in the given function."
According to the question,
For linear function we can put all the real numbers for the independent variable 'x' that is ( -∞ , ∞).
Domain of a linear function = ( -∞ , ∞).
Output values of the linear function is set of all real numbers (-∞,∞).
Range of a linear function = (-∞,∞).
For cubic function
Cubic function is an odd polynomial . One end extends to +∞ and other end to -∞.
Domain and range of cubic function (-∞,∞).
Hence, two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.

27 is 45% of what number?
Answer:
60%
Step-by-step explanation:
The first step is to divide 27 by 45 to get the answer in decimal form:
27 / 45 = 0.6000
Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:
0.6000 * 100 = 60.00%
60
Step-by-step explanation:
If you take 45 percent of a number and get 27, then what is that number? In other words, you know that 45 percent of a number is 27 and you want to know what that initial number is.
To solve this problem you multiply 27 by 100 and then divide the total by 45 as follows: (27 x 100) / 45
When we put that into our calculator, we get the following answer:
60
Therefore, the answer to "27 is 45 percent of what number?" is 60, and you can also derive that 45 percent of 60 equals 27.

How many points of intersection are there between the graphs of the hyperbola and ellipse?
3x2 – 4y2 + 4x – 8y +4= 0
3x2 + y2 + 4x – 3y +4= 0
A.0
B. 1
C. 3
D.4
The point of intersection is the point where two or more functions meet.
The graphs of the hyperbola and ellipse have 0 point of intersection
The given parameters are:
[tex]\mathbf{3x^2 - 4y^2 + 4x - 8y + 4 = 0}[/tex]
[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 0}[/tex]
To determine the points of intersection, we simply equate both equations.
So, we have:
[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 3x^2 - 4y^2 + 4x - 8y + 4 }[/tex]
Cancel out the common terms
[tex]\mathbf{y^2 - 3y = - 4y^2 - 8y }[/tex]
Collect like terms
[tex]\mathbf{y^2 +4y^2= 3y - 8y }[/tex]
[tex]\mathbf{5y^2= - 5y }[/tex]
Divide through by 5
[tex]\mathbf{y^2= - y}[/tex]
Divide through by y
[tex]\mathbf{y= -1}[/tex]
The system of equation does not give room to calculate the x-coordinate at the x-axis.
Hence, the graphs of the hyperbola and ellipse have 0 point of intersection

You are given that a = 6.54 (to 3 significant figures) and b = 123 (to 3 significant figures).
Calculate upper and lower bounds for each of the following, give your answers to 3 significant figures:
(a) a + b
(b) ab
(c) a/b
(d) b - 1/a
The upper and lower bounds for the numbers are illustrations of approximation
How to calculate the upper and lower boundsThe numbers are given as:
a = 6.54 (to 3 significant figures)
b = 123 (to 3 significant figures)
(a) a + b
We have:
a + b = 6.54 + 123
a + b = 129.54
When approximated, the bounds to three significant digits are:
Lower bound = 129
Upper bound = 130.1
(b) ab
We have:
ab = 6.54 * 123
a + b = 804.42
When approximated, the bounds to three significant digits are:
Lower bound = 804
Upper bound = 805
(c) a/b
We have:
a/b = 6.54/123
a/b = 0.0531707317
When approximated, the bounds to three significant digits are:
Lower bound = 0.0531
Upper bound = 0.0532
(d) b - 1/a
We have:
b - 1/a = 123 - 1/6.54
b - 1/a = 122.847094801
When approximated, the bounds to three significant digits are:
Lower bound = 122

Find the measure of the marked angles.
The measure of the angles is
___ degrees
Answer:
43 degrees
Step-by-step explanation:
The angles are vertical angles. All vertical angles are congruent meaning that these 2 expressions can be set equal to each other. Then, solve for x and finally plug x back in to get the answer.
First, set of the equation(4x+19)=(6x+7)
Then, subtract 7 from both sides4x+12=6x
Next, subtract 4x both sides12=2x
Finally, divide both sides by 2x=6
Now, we can plug 6 into the expression given to show that both angles are 43 degrees.
