Answer:
2x^2+7x and 8y+3x
Step-by-step explanation:
Okay for the first one when you combine like terms you are adding the ones with the same terms so the ones that have X in it you add, the one with Y you add so it would be
2x+6x=8x ----> 8x-5x=3x
5y+3y=8y so
8y+3x
same thing for the other one so the answer is:
2x^2+7x

Convert to a mixed number and simplify: 83 over 6
Answer:
[tex]13\frac{5}{6}[/tex]
Step-by-step explanation:
[tex]\frac{60}{6}=10[/tex] (low estimate to make later estimates easier)
[tex]10+\frac{24}{6} =14[/tex] (high estimate, must make lower)
[tex]14*6\neq 83[/tex] (incorrect estimate)

The mean is the average of the data. I remember this by thinking, 'the average person is mean.'To find the average, or mean, you would add all of the variables together and divide it by the number of variables. The number of variables here would be 10, because there are 10 litters.We would add the amount of kittens together and divide it by 10. This will get us 57 ÷ 10 = 5.7.To find the MAD, take the mean (5.7) and subtract each number from 5.7, then square it. For example... [tex][5.7 - 4]^{2}[/tex] would be solved by first subtracting what is in the parenthesis (PEMDAS) which gets us 1.7, then multiplying it by itself (1.7 • 1.7) which equals 2.89.Repeat this process for all data points.What I got for all of the data points [listed below]Once you get all of the data points, you add them all together. This gets you 32.5.Now you divide 32.5 by 10, (to find the average of it) which gets you 3.25.2.89.49.49.09.091.695.295.295.2910.89If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
Find the distance between the points(-9,8) and (7,-10) if one unit represents one kilometer
Answer:
√X2-X1+√Y2-Y1
=√7-(-9) +√-10-8
=√16 + √-18
=4 + -(√18)
=4 + (-3√2)
=-0.24
Step-by-step explanation:
by answering this you must use the distance formula and label -9 as X1 , 8 as Y1 and 7 as X2 , -10 as Y2 then you put X2-X1 in the same root sine do the same at Y2-Y1.

Step-by-step explanation:
Use the given expression to calculate surface area by substituting the numbers for the corresponding variables.
A.3.14(rs +r²) . . . . for r = 6 and s = 4
= 3.14(6·4 +6²)
__
B.Evaluating the above expression gives the surface area:

Find the quotient of z1 by 22. Express your answer in trigonometric form
HELP ASAP
Condense z₁ and z₂ into their exponential forms:
z₁ = 3 (cos(π/4) + i sin(π/4)) = 3 exp(i π/4)
z₂ = 7 (cos(3π/8) + i sin(3π/8)) = 7 exp(i 3π/8)
Then the quotient of z₁ and z₂ is
z₁ / z₂ = 3/7 exp(i (π/4 - 3π/8)) = 3/7 exp(-i π/8)
and in trigonometric form,
z₁ / z₂ = 3/7 (cos(-π/8) + i sin(-π/8))) … … … D

a) what is the combined height for Janet's mother and father?
b) Is Janet more or less than half of her parent's combined height?
Answer:
1.5+1.2=2.7
2.7÷2=1.35
1.35=dad's height

b) more than half
A point at (-4,10) in the standard (x,y) coordinate
plane is translated right 10 coordinate units and down
4 coordinate units. What are the coordinates of the
point after the translation?
Translation involves changing the position of a point along the standard coordinate plane
The coordinate of the point after translation is (6,6)
How to translate the pointThe point is given as:
(-4,10)
When the point is translated 10 units right, the new coordinate becomes
(-4 + 10,10)
(6,10)
When the point is translated 4 units down, we have:
(6,10 - 4)
(6,6)
Hence, the coordinate of the point after translation is (6,6)

Two similar rectangles have a scale factor of 2. What is the ratio of their areas?
Answer:
Step-by-step explanation:
If the polygons are similar, this means that the ratio of their corresponding sides are equal. This ratio is what we commonly refer to as the scale factor. The ratio of the area of similar polygons is equal to the SQUARE of SCALE FACTOR. For this item since the scale factor is 2, the ratio of the areas is equal to 4.
What is the value of s?
Answer:
63
Step-by-step explanation:
(s-13) +s = s + 50
2s - 13 = s + 50
add 13 both sides, subtract the s from both sides
s = 63
Answer:
s = 63°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
s + 50 is an exterior angle of the triangle , then
s + 50 = s - 13 + s
s + 50 = 2s - 13 ( subtract s from both sides )
50 = s - 13 ( add 13 to both sides )
63 = s
