Answer:
-1 -y/5
Step-by-step explanation:
-5x + y = 1
Subtract yy from both sides.
-5x=1-y
−5x=1−y
2 Divide both sides by -5−5.
x=-\frac{1-y}{5}
x=−
5
1−y
-10x+2y=-2
Factor out the common term 22.
2(5x+y)=-2
2(5x+y)=−2
2 Divide both sides by 22.
5x+y=-1
5x+y=−1
3 Subtract yy from both sides.
5x=-1-y
5x=−1−y
4 Divide both sides by 55.
x=\frac{-1-y}{5}
x=
5
−1−y

A cube is cut in to three parts by vertical slices find the volume of the shaded area The length and width of original is 20 cm and cut part is 10 cm
Answer:
4000 cm^3
Step-by-step explanation:
Note that no image was attached for reference purposes
Step one:
We are given that the original length and width of the cube is 20cm
if the cut part is 10cm
hence the dimension of the cut part is
lenght = 20cm
Width= 20cm
Hieght= 10cm
Step two:
the volume of the cut part will be
Volume= 20*20*10
Volume= 4000 cm^3
is 4 a factor of 72
Answer:
Yes
Step-by-step explanation:
Yes. 72 divided by 4 would be 18, so it is a factor
Answer:
Yes
Step-by-step explanation:
Yes because 4 x 18 = 72
72 divided by 18 = 4
I know this because if you multiply 4 x 18 you will get 72. To check you can do the inverse operation, which is division, so with that being said, 72 divided by 18 = 4.
I explained to so you can have a better understanding. Have a great day!

PLEASE HELP ANYONE!!!Write the exponential regression representing the population of Lazy Town as a function of time in years
Given:
[tex]R^2=0.92,a=8000,b=0.9[/tex].
Exponential regression model is
[tex]y_1\sim a(b)^{x_1}[/tex]
To find:
The exponential regression representing the population of Lazy Town as a function of time in years.
Solution:
We have, [tex]a=8000,b=0.9[/tex].
Exponential regression model is
[tex]y_1\sim a(b)^{x_1}[/tex] ...(i)
Putting [tex]a=8000[/tex] and [tex]b=0.9[/tex] in (i), we get.
[tex]y_1\sim 8000(0.9)^{x_1}[/tex]
Thus, [tex]y_1\sim 8000(0.9)^{x_1}[/tex] is the required exponential regression representing the population of Lazy Town as a function of time in years.

Miles and kilometers are twi different scales for measuring distances. A 5-kilometer race is approximately 3.1 miles, and a 10-kilometer race id approximately 6.2 miles. Write an equation that shows the approximate distance in kilometers as a function if the distance in miles
Answer:
[tex]x=\dfrac{y}{0.62}[/tex]
Step-by-step explanation:
[tex]5\ \text{km}=3.1\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{3.1}{5}=0.62\ \text{miles}[/tex]
[tex]10\ \text{km}=6.2\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{6.2}{10}=0.62\ \text{miles}[/tex]
Let [tex]y[/tex] be the distance in miles. So distance in km is given by
[tex]x=\dfrac{y}{0.62}[/tex].
The equation that shows the approximate distance in kilometers as a function if the distance in miles is [tex]x=\dfrac{y}{0.62}[/tex].

1. ABCD is an isosceles trapezoid. m < A = 6x + 12 and m < d = 2x + 20. Angles B&C are congruent. What is the measure of angles B&C?
2. QRST is a rectangle. RS = 12k +5 and QT = 145. what is the value of 'k'?
Answer:
∠ B = 123°, ∠ D = 57°
Step-by-step explanation:
Each lower base angle is supplementary to the upper base angle on the same side.
∠ A and ∠ D are on the same side, then
6x + 12 + 2x + 20 = 180
8x + 32 = 180 ( subtract 32 from both sides )
8x = 148 ( divide both sides by 8 )
x = 18.5
Thus
∠ A = 6x + 12 = 6(18.5) + 12 = 111 + 12 = 123°
∠ D = 2x + 20 = 2(18.5) + 20 = 37 + 20 = 57°
The lower base angles and the upper base angles are congruent, so
∠ B = ∠ A = 123°
∠ C = ∠ D = 57°
Answer:
Step-by-step explanation:
#1). It could be good to provide us with the picture, because the answer depends from the angle we choose for letter A.
--- If angle A is acute, then m∠A = m∠D
and
6x + 12 = 2x + 20 ⇒ x = 2
m∠A = m∠D = 24°
m∠B = m∠C = 180° - 24° = 156°
--- If angle A is obtuse, then m∠A + m∠D = 180°
and
6x + 12 + 2x + 20 = 180 ⇒ x = 18.5
m∠A = m∠B = 6(18.5) + 12 = 123°
m∠D = m∠C = 2(18.5) + 20 = 57°
#2). 12k + 5 = 145
12k = 140
k = [tex]\frac{35}{3}[/tex] = [tex]11\frac{2}{3}[/tex]
