Answer:
5+√6
Step-by-step explanation:
(3√3 -2√2) ÷ (√3-√2 )
= (3√3 -2√2) (√3+√2) ÷ (√3 -2√2) (√3+√2)
= (9+3√3√2-2√2√3-4) ÷ ((√3)^2 -(√2)^2)
=(9+3√6-2√6-4) ÷ (3-2)
= (5+√6)
he function f(x) = –x2 – 4x + 5 is shown on the graph. On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 2, 9), and goes through (1, 0). Which statement about the function is true? The domain of the function is all real numbers less than or equal to −2. The domain of the function is all real numbers less than or equal to 9. The range of the function is all real numbers less than or equal to −2. The range of the function is all real numbers less than or equal to 9.
Answer: The range of the function is all real numbers less than or equal to 9.
Step-by-step explanation:
Since the parabola opens down, that means the vertex marks the maximum y-value of the function.The vertex is (-2, 9). Therefore the maximum y-value is 9 and the range of the function will be all real numbers less than or equal to 9.There are no limits to the domain.Answer:
The range of the function is all real numbers less than or equal to 9.

Find x,cb, and do, in the image below AB is the angle bisector of
**Fill in the blanks !!
x = 9
CB = DB = 61
Step-by-step explanation:
∠CAB = ∠DAB
So, DB = CB {Sides opposite to equal angles are equal}
6x +7 = 3x+ 34
Subtract 7 from both sides.
6x = 3x + 34 - 7
6x = 3x + 27
Subtract 3x from both sides.
6x - 3x = 27
3x = 27
Divide both sides by 3
x = 27/3
x = 9
DB = 6x +7
= 6*9 + 7
= 54 + 7
DB = 61
CB = 3x + 34
= 3*9 + 34
= 27 + 34
CB = 61
The diagonals of a quadrilateral must be bisect each other and be perpendicular to gurarantee that the quadrilateral is a parrelogram
Answer:
False
Step-by-step explanation:
A quadrilateral is a closed geometrical figure that have four sides and four vertices. Thus the following includes in a quadrilateral : parallelogram, square, rhombus, rectangle and trapezium.
If the diagonals of the quadrilateral bisects each other and are perpendicular to each other, then the quadrilateral forms a rhombus.
Hence the answer is FALSE.

Identify the constant term in the expression:
3x + 45y + 13z + 43
Answer:
a constant term is a term in an algebraic expression that does not contain any variables
Therefore your answer is 43
Answer:
The constant term in the above expression is 43 as it has no variable where 3 has x variable 45 has y variable and 13 has z variable
So 43 is the constant term in the above expression
What is the product?

Answer:
1
Step-by-step explanation:
So we can actually simplify the exponents here. The power rule for exponents is that when multiplying, you add the exponents. So,
3 + (-3) = 0
so the number is now 4^0.
Everything by the power of 0 is equal to 1, so the answer is 1.

The simplified expression of (3x – 5 – 7x²) – (–2 + 6x² – 5x) is
-x² + 8x - 3
To subtract polynomials. Specifically, we will solve the expression
(3x - 5 - 7x²) - (-2 + 6x² - 5x) step by step using the rules of polynomial subtraction.
To subtract polynomials, we need to combine like terms and simplify the expression.
Step 1: Distribute the negative sign in the second parentheses:
(3x - 5 - 7x²) + (2 - 6x² + 5x)
Step 2: Now, group the like terms together. Like terms have the same variables raised to the same powers:
(3x + 5x) + (-7x² + 6x²) + (-5 + 2)
Step 3: Combine the like terms:
8x - x² - 3
So, the final simplified expression after subtracting the polynomials is:
-x² + 8x - 3
1. First, we distribute the negative sign by changing the signs of all the terms in the second parentheses.
2. Next, we group the like terms together, which means combining the terms with the same variable and exponent.
3. Finally, we combine the coefficients of the like terms to obtain the simplified polynomial expression.

Mary's mistake was that she didn't take into account of the power that 10 is raised to; since 2.01 is multiplied by 10 to the 6, it makes 2.01 bigger. You can also expand the number to check:

Si Martha retira de su cuenta el 10% para los transportes del mes. ¿Cuál es el nuevo saldo de la cuenta?
Respuesta:
0,9 veces
Explicación paso a paso:
Deje que la cantidad en la cuenta de Martha se denote como x, que es la cantidad en la cuenta = x
Porcentaje retirado para transporte = 10%
El porcentaje total siempre será del 100%
Por lo tanto, si se retira el 10%, entonces; el porcentaje restante es:
Porcentaje total: porcentaje gastado en transporte
(100% - 10%) * monto en cuenta
90% * x = 0,9 * x = 0,9x
Saldo de cuenta nueva = 0.9x
Question 7(Multiple Choice Worth 1 points) (08.02 LC) Eva conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 3 hours. What does this range say about the data? The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours. All the students surveyed spend exactly 3 hours surfing the Internet. All the students surveyed spend an average of 3 hours surfing the Internet.
Answer:
The answer is "Option B".
Step-by-step explanation:
The difference between most time and also the least spending time on Internet surfing is 3 hours. Since we do not have charts for tables etc., only 3 can be used we need. A range is defined as the difference between the largest and the smallest amounts. The range between both the largest as well as the smallest is unique. In this reply, it tells us that the gap between most time and the fewer hours invested surfing the web is 3 hours.
In option A, it is wrong since the range has nothing to do with formulas. (Of course, the dividend with a divisor results in a quotient). Only subtraction and not division may be achieved.In option C, when all surf for exactly one hour, it could take the largest time of 3 hours and 3 hours, the last time. Add it into the equation and the range of the data present would've been 0.In option D, It is erroneous even as the range is not the mean, and the mean seems to be the average. We search for both the range, not the mean.The answer is B
The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
This answer is proven 100% correct.

Find the slope of the line passing through the points (-2, -8) and (9,-8).
slope:
To get that answer, apply the slope formula
m = (y2 - y1)/(x2 - x1)
m = (-8 - (-8))/(9 - (-2))
m = (-8 + 8)/(9 + 2)
m = 0/11
m = 0
Any line with slope 0 is completely horizontal.
As a quick rule of thumb: if the y coordinates of the two points are the same, then the slope is 0 on this horizontal line.

find the angle measures given the figure is a rhombus.
Answer:
m<1=74
m<2=37
Step-by-step explanation:
m<2 is the same as the other angle, 37 degrees. So now we need to find the other angle in the triangle.
37+37+x=180.
The total degree of a triangle is 180.
x=106
Subtract that from 180 to get m<1.
180-106=74

What’s the answer? Help
Answer:
$14
Step-by-step explanation:
x = price of scarf 1
y = price of scarf 2
together they cost $25
x + y = 25
one scarf costs $3 more than the other
x = y + 3
now we use that in the first equation again
y+3 + y = 25
2y +3 = 25
2y = 22
y = $11
=> x = y +3 = 11 + 3 = $14

Find the equation of the line parallel to y = -3x + 4 with a y-intercept of -10
Answer:
y=-3x-10
Step-by-step explanation:
Hi there!
We need to find the equation of the line parallel to y=-3x+4 that has the y intercept of -10 (the point (0, -10))
Parallel lines have the same slope
The slope of y=-3x+4 is -3 (it is in the placement of where m (slope) is in y=mx+b)
So the slope of the new line parallel to y=-3x+4 is also -3
Here is the equation of that line so far:
y=-3x+b
b is a placeholder for the y intercept
However, we are given the y intercept as -10, so substitute -10 as b into the equation
y=-3x-10
There's the equation of the line parallel to y=-3x+4 with a y intercept of -10
Hope this helps!
