Answer:30-(-6) is the same as 30+6. 36 is the value of the expression 30-(-6). If it were written:
30x(-6) = -180
30-6 = 24
But 30-(-6) = 36

Write an equation in slope intercept form that goes through the point (5,-7) and is PARALLEL to the line y=-3x+8
Answer:
there is no line parallel to y = -3x + 8 that goes through (5, -7). this point falls on this line
Step-by-step explanation:
[tex]y = - 3x + 8[/tex]
[tex] - 7 = - 3(5) + b \\ - 7 = - 15 + b \\ b = 8[/tex]
The answer is
[tex]y = - 3x + 8[/tex]

What is the measure of Zx?
Urgent Help Please!!!
Answer:
the x = 50 degrees, just because the sum of the angles of the triangle = 180 degrees, then the ABD triangle = 50 + 78+52 = 180, also the line AC will have 180 degrees, so the sum 78 + 102 = 180, and the BCD triangle is 102+ 50+28 = 180 and the ABC triangle also is 50+102+28=180
A rectangular cake pan has a volume of
234
cubic inches. If the length of the pan is
9
inches and the width is
13
inches, what is the height of the pan?
Step-by-step explanation:
volume of a rectangular pan = length of the pan × width of the pan × height of the pan
V=l.b.h
234=9.13.h
h=234/9×13
h= 2in.
hope this helps you.
Answer:
2 inches
Step-by-step explanation:
V= 234, L=9, W=13, H=?
V= LxBxH
234= 9x13xH
234= 117H
divide through by 117
234/117 = 117H/117
H= 2inches
Find the equation of the linear function represented by the table
y 6 9 12 15
x 1 2 3 4
9514 1404 393
Answer:
y = 3x +3
Step-by-step explanation:
The slope of the line can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
Using the first two sets of table values, this is ...
m = (9 -6)/(2 -1) = 3/1 = 3
You can find the point-slope equation using the form ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -6 = 3(x -1) . . . . . using the first point in the table
Solving for y gives ...
y = 3x -3 +6 . . . eliminate parentheses, add 6
y = 3x +3

Which one of the following is the same as 72 dekaliters ?
A. 72 dal
B. 72 dI
C. 72 deciliters
D. 72 ml
Answer:
72 dal
Step-by-step explanation:
short form to dekaliter is dal
Based on the abbreviations for various units of measurements, the best answer here is A. 72 dal
Units of measurements have shorter forms such as:
Liters ⇒ LMilliliter ⇒ MLDekaliters ⇒ DALAs the short form of dekaliter is dal, the first option must be correct as it is the same as 72 dekaliters albeit in a shortened form.
We can therefore conclude that 72 dal and 72 dekaliters are the same.

B. A scuba diver descends 40 m from sea level and then descends another 10 m.
C. Gabriella charges $300 on her credit card and then pays the $300 credit card bill.
D. A helium atom has 2 positively charged protons and 2 negatively charged electrons.
Answer:
C and DStep-by-step explanation:
Additive inverse is when two numbers add up to zero.
A. Mia walked 5 mi north and then walked 5 mi west.
False. It would be true if the directions are opposite.B. A scuba diver descends 40 m from sea level and then descends another 10 m.
False. It is - 40 - 10 = -50 m, not zeroC. Gabriella charges $300 on her credit card and then pays the $300 credit card bill.
True. - $300 + $300 = 0D. A helium atom has 2 positively charged protons and 2 negatively charged electrons.
True. The atom has neutral charge as + 2 + (-2) = 0Answer:
It is given
4x+3y=24
We can also write it as
3y=24−4x
y=324−4x
Substituting x=0 in the given equation
y=324−4(0)
So we get
y=324
By division
y=8
Substituting x=3 in the given equation
y=324−4(3)
So we get
y=312

hi could someone explain this??
im thinking it is J=50(15)^t???
Answer:
J=15t+50
Step-by-step explanation:
The equation to represent this situation will be in the form J=mt+b where b is the starting value of love units, m represents the "love units" that are multiplied by the number of week, t is the number of weeks, and J represents Jack's love at that specific week.
The equation becomes: J=15t+50
To check, the equation should equal 50 when t=0, 65 when t=1, and 80 when t=2.
Checking t=0:
J=15(0)+50=0+50=50
Checking t=1:
J=15(1)+50=15+50=65
Checking t=2:
J=15(2)+50=30+50=80
The equation J=15t+50 does model the behavior of Jack's love at any week t based on the given data. Note that the equation used was based on slope intercept form (y=mx+b) due to the given data having a linear relationship.
A water tank holds 1500 liters of water when it is full. If 2/3
of the tank is full, how
much more liters of water are needed to make the tank full?
fraction word problem
Answer: 500
Step-by-step explanation: A third of 1,500 is 500, and 2/3 of 1,500 is 1,000. So, 1,500 - 1,000 = 500 liters. Therefore, in order to make the tank full, 500 liters of water are needed.
Circle A has a circumference of 25 centimeters.
Circle B's diameter is 3 times as long as circle A's
diameter.
What is the circumference of circle B?
The circumference of circle B would be; 74.98 cm.
What is the circumference of the circle?The circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.
The circumference of the circle = 2πr
We have been given that Circle A has a circumference of 25 centimeters.
And Circle B's diameter is 3 times as long as circle A's diameter.
Thus, the Diameter of Circle B = 3 x the Diameter of Circle A
Since The circumference of the circle A = 2πr = 25
2πr = 25
r = 25/ 2π
r = 3.98 cm
The Diameter of Circle A = 2 x 3.98 = 7.96 cm
Since Diameter of Circle B = 3 x the Diameter of Circle A
Diameter of Circle B = 3 x 7.96 cm
= 23.88 cm
Radius = 23.88 / 2
Hence, the circumference of circle B = 2πr
= 2 x 22/7 x 23.88 / 2
= 74.98 cm
