Answer:
y = 4/3 x - 4
Step-by-step explanation:
The slope-intercept form of the equation of a line
The equation of a line can be expressed in several forms. One of them is the slope-intercept form:
y = mx + b
Where
m = slope
b = y-intercept
We are required to convert the equation of the line:
4x - 3y = 12
It can be done by solving for y.
Subtracting 4x:
- 3y = - 4x + 12
Dividing by -3;
y = 4/3 x - 4
Can someone please help and please make sure it’s right :)
From corresponding angles theorem, we can see the 2 angles are equal.
16x+13=18x-1
2x=14
x=7
Done!
Any questions just leave them in the comments and I will answer.
Answer:
Step-by-step explanation:
i think you do 34x + 12
bc it is a same side interior angle and i think that equals 180 and then you
34x+12=180
-12 - 12
34x= 168

34 34

i.dk i think it is 5 bc you get 4.98 so you round the 8 and it makes it a 4.10 which is 5
14. The equation of the line that passes through the
points (-2,2) and (3, -3) is
1. x + y = 5
2.x-y=5
3. y - x = 5
4. y = x
5. y = -X
Answer:
5. y = -x
Step-by-step explanation:
First, you need to find the slope of the line.
[tex]m = \frac{2 - (-3)}{-2 - 3} = \frac{5}{-5} = -1[/tex]
Now, using either point substitute into the point-slope form for a line:
[tex]y - y_{1} = m(x - x_{1} )[/tex]
Using (-2,2) for [tex](x_{1} , y_{1} )[/tex] we get y - 2 = -1(x +2)
y - 2 = -x - 2
y = -x
Answer 5 is the correct answer
how do i figure out prime numbers
Answer:
You can figure out prime numbers by simply knowing that you can divide that number not more than one. For example, you could know that a prime number is 7 because you can only divide it once like 7 divided by 1. While for number 14, you can divide it twice which isn't a prime number because there is 14 divided by 2 and 14 divided by 1 which is more than one to divide. That's possibly an easy way to understand how to figure them out.

1) Um barbante tem 10,85 metros de comprimento. Se você dividir em 5 pedaços de mesmo comprimento, quantos centímetros terá cada pedaço? * 1 ponto (a) 2,17 cm (b) 217 cm (c) 21,7 cm (d) 0,217 cm
Answer:
(b) 217 cm
Step-by-step explanation:
The computation of the number of centimeters will each have is shown below:
= Length of the string ÷ number of pieces
= 10.85 meters ÷ 5
= 2.17 meters
= 217 centimeters
hence, the correct option is b.

Step-by-step explanation:
please help me with this
since m is parallel to n, this means that the two angles are alternate angles. Hence, 46°=6x-2
Calculate and you should get x = 8°
Can someone plz help me with this and explain how to do this math problem
Answer:
greater
Step-by-step explanation:
the reason is because if you allow x to have a value that is less than 3,
[tex] \sqrt{x - 3} [/tex]
will produce a square root of a negative number, and the square root of a negative number requires the use of imaginary numbers, therefore limiting x to greater than or equal to 3 prevents this, also, consideration should be given to the fraction
[tex] \frac{3}{x + 2} [/tex]
if x has a value of -2 it causes the denominator of the fraction to be 0, the denominator should never be 0, by limiting x to greater than 3 to prevent the problem above you are already taking care of x not being able to be -2 since greater than 3 already excludes -2

Robert has 5 pizzas at his birthday party, and each pizza is cut into 5 slices. His guests take 2 pieces from each pizza. What equation would represent the amount of pizza that is left?
Answer:
3 whole pizzas left
Step by step explanation:
well if the quest take 2 out of every 5 wholes then u would be left with 3
5 5 5
so u add then together and get [tex]3\\ 5[/tex] and add that 5 times
so u would get [tex]15\\ 5[/tex] and if u simplify u would have 3 whole pizzas left

Solve the simultaneous equations by substitution
3y - 2x = -7
5x + 3y = 28
Answer:
(5, 1 )
Step-by-step explanation:
Given the 2 equations
3y - 2x = - 7 → (1)
5x + 3y = 28 → (2)
Rearrange (1) expressing 3y in terms of x by adding 2x to both sides
3y = - 7 + 2x
Substitute 3y = - 7 + 2x into (2)
5x - 7 + 2x = 28
7x - 7 = 28 ( add 7 to both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5(5) + 3y = 28
25 + 3y = 28 ( subtract 25 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (5, 1 )
Answer:
-(3y-2x= -7)
3y+5x= 28
-3y+2x= 7
3y+5x= 28
7x=35
7x/7= 35/7
x=5
5(5)+3y= 28
25+3y=28
3y= 28-25
3y=3
3y/3=3/3
y= 1
3y-2x= -7
3(1) -2x= -7
3-2x= -7
-2x= -7-3
-2x= -10
-2x/-2=-10/-2
x= 5

5x+3y=28
5(5)+3(1)=28

Answer:
x = - 6
Step-by-step explanation:
Equation
1/3 * (-9x +12) = 22 Multiply both sides by 3
Solution
3 * 1/3(-9x + 12) = 22*3
- 9x + 12 = 66 Subtract 12 from both sides.
-9x = 66 - 12 Combine
-9x = 54 Divide by -9
x = 54/-9
x = - 6
Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa .
-Abby walks at a speed of 8 feet per second.
-Melissa walks at a speed of 9 feet per second.
Abby had been walking for BLANK seconds when both students had walked exactly the same distance. (round to the nearest whole)
please help me
Answer:
270 seconds
Step-by-step explanation:
Melissa's time = x seconds
Abby's time = (x + 30) seconds
Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.
But, speed = [tex]\frac{distance}{time taken}[/tex]
For Abby,
8 = [tex]\frac{distance}{(x + 30)}[/tex]
distance = 8(x + 30) ................. 1
for Melissa,
9 = [tex]\frac{distance}{x}[/tex]
distance = 9x ............. 2
From equations 1 and 2, for the same distance;
8(x + 30) = 9x
8x + 240 = 9x
x = 240 seconds
Abby's time = (x + 30)
= (240 + 30)
= 270 seconds
So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.
The time taken is 270 seconds.
Given that,
Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa . Abby walks at a speed of 8 feet per second. Melissa walks at a speed of 9 feet per second.Here we assume Melissa time be x and Abby time be x + 30Based on the above information, the calculation is as follows:
8(x + 30) = 9x
8x + 240 = 9x
x = 240
So Abby time should be
= 240 + 30
= 270

mr. Murphy's Megan graph to show his class the amount of water person consumes from food and beverages over time.
a person consumes 12 gallon of water each day (i already answerd this part)
(this part is the one im asking about )
complete the equation to show the relationship between X the number of days and Y the amount of water consumed
Y = ? X
Answer:
y = 12x
Step-by-step explanation:
From the question, we are told that a person consumes 12 gallons of water each day
Now, we want to complete an equation
From the question, x is the number of days and y is the amount of water consumed
Thus, mathematically, we have the equation as;
y = 12x
since in the first day, 12 gallons is consumed, the second will be 12 * 2 and so on
So the amount of water depends on rate number of days
