Remmi wrote the equation of the line y = one-third (x + 2) He solved for x and got x = 3 y minus 2 Which of the following is an equivalent equation for x?
Answer:
x = 3y - 2
Step-by-step explanation:
Given the equation y = 1/3(x+2), we are to make x the subject of the formula;
y = 1/3(x+2)
Cross multiply
3y = x+2
Subtract 2 from both sides
3y - 2 = x+ 2 -2
3y - 2 = x
Swap
x = 3y - 2
This give the required equation

Which equation of the line passes through the point (0,4) and is perpendicular to the lines whose equation is y=-1/2x + 3
Answer:
y = 2x+4
Perpendicular lines, when you multiply their gradient, you will get -1. You can also find the negative reciprocal, which is 2. The point (0,4) is the y intercept, which is for. Hence, the equation is y=2x+4

What is the relationship between the angles that are formed by two intersecting lines?
Hi there!
Adjacent angles, or angles that are next to each other, add up to 180 degrees. They are supplementary.
Examples: 1 and 4, 3 and 4, 2 and 3, 1 and 1
Opposite angles, or angles that are opposite of each other, have the same measure.
Examples: 1 and 3, 2 and 4
I hope this helps!

: a^2-7a =0
Answer:
a = 0 or a = -7
Step-by-step explanation:
We are going to solve this quadratic equation by factorizing.
a² - 7a = 0
a(a - 7) = 0
a = 0 or a - 7 = 0
a = 0 or a = -7

Lucia is making blackberry jam. She starts with 25 cartons of blackberries. After making 9 jars of jam, she has 10 cartons of blackberries left. Lucia's jars all have the same capacity. Select true or false for each statement.
Answer:
A = true
B = false
C = false
D = True
Step-by-step explanation:
Cartons of blackberries = 25
Jars of blackberry jam made = 9
Cartons of blackberries left = 10
Cartons of blackberry used = Cartons of blackberries - Cartons of blackberries left
= 25 - 10
= 15
Cartons of blackberry used = 15
Cartons of blackberry used per jam = Cartons of blackberry used / Jars of blackberry jam made
= 15/9
= 5/3
A = true
15 jars of blackberry = Cartons of blackberry used per jam × jars of black berry made
= 5/3 × 15
= 75/3
= 25 cartons of blackberry
B = false
She can make 15 jars of blackberry jam using 25 cartons of blackberry
C = false
Cartons of blackberries left = 10
Number of blackberry jam made with 10 cartons of blackberry = Cartons of blackberries left / Cartons of blackberry used per jam
= 10 ÷ 5/3
= 10 × 3/5
= 30/5
= 6

The level of the tide in a harbor changes from 813 8 1 3 feet to 256 2 5 6 feet above sea level over a period of 212 2 1 2 hours. What is the change in tide level per hour over this period of time? Feet per hour
Answer:
-2.63 ft./hour
Step-by-step explanation:
The level of the tide in a harbor changes from 813 feet to 256 feet above sea level over a period of 212 hours. What is the change in tide level per hour over this period of time?
Solution:
The initial tide level was 813 feet while the final tide level was 256 feet above sea level within a period of 212 hours.
The change in tide level per hour is the ratio of the change in tide level to the period taken. Hence:
Change in tide level per hour = (Final tide level - initial tide level) / time taken
Change in tide level per hour = (256 ft. - 813 ft.) / 212 hours
Change in tide level per hour = -2.63 ft./hour
Someone help- I don't know how to solve this- maybe my teacher typed it in wrong? 2.4(m - 3) = 3.8 = -8.2
Answer:
m = 4.58
Step-by-step explanation:
Given equation :
2.4 ( m - 3) = 3.8
So now we open the brackets and multiply the terms.
⇒ 2.4 m - 7.2 = 3.8
⇒ 2.4 m = 3.8 + 7.2
⇒ 2.4 m = 11
⇒ m = [tex]\frac{11}{2.4}[/tex]
⇒ m = 4.58
Therefore, the correct value of the variable m by solving the equation is 4.58
What Has a central point that stays fixed and everything else moves around that point in a circle- full rotation is 360 degrees.
Answer:
Rotary motion.
Step-by-step explanation:
Motion describes the movement of objects with respect to time.
When an object performs a circular or rotary motion, every point on the object moves around a central point in a continuous manner. Examples of objects that performs circular motion are: blades of an electric fan, rotation of the earth about its axis, the wheel of a moving bicycle etc.
From the cited examples, it would be observed that all points on the objects moves around a fixed central point.

Answer:
2.478 million at the end of 2015
Step-by-step explanation:
Multiply the amount of population at the end of 2012 times 6%
2.1 times 0.06 = 0.126 million
So, at a constant rate, yearly, the population of Dubai increases 0.126 million
2015-2012 = 3
0.126 times 3 = 0.378 million
2.1 + 0.378 = 2.478 million

Function Q: y =1/3x + 2 Identify function Q as linear or nonlinear. State a reason why it is linear or nonlinear.
Answer:
A linear function is written in slope-intercept form as:
y = a*x + b
Where a is the slope and b is the y-intercept.
So any function of this shape, is a linear function, such that when graphed it is a straight line.
In this case, the function you wrote is:
Q: y = 1/3x + 2
Now, if the function is exactly what you wrote, then x is in the denominator:
y = 1/(3*x) + 2
Clearly, this is different than the general linear equation you can see above (here the variable is in the denominator) then in this case Q is non-linear.
If instead, the actual function Q is:
Q: y = (1/3)*x + 2
Then this is a linear equation, where the slope is 1/3 and the y-intercept is 2.
What is the approximate value of tan C?
Answer:
B. 0.38
Step-by-step explanation:
Tan = Opposite/Adjacent
Opposite of angle C = 5 and adjacent = 13
Hence tan C = 5/13 = .38
Answer:
Step-by-step explanation:
Remark
You are given a right angle triangle, so it is possible to define the Tangent directly.
Definition
The tangent = opposite side / adjacent side.The opposite side (AB) is the side not connect to the angle's vertex (C)The adjacent side (BC) is the side that is connect to the angle's vertex (C). It is not the longest side in triangle. The hypotenuse (BC) is the longest side.Solution
Opposite Side = 5
Adjacent side = 13
Tan(C) = 5/13 = 0.3846

Answer:
Step-by-step explanation:
There are three surfaces to add up to.
A1, the top surface of the cone (r=1,h=2)
A2, The curved surface of the cylinder (r=1 , h = 13-2 = 11)
A3, The circular base of the cylinder (r=1)
The slant height of the cone, s = sqrt(1^2+2^2), s = sqrt(5)
The length (circumference of the base), l = 2 pi r = 2pi r = 2pi
The area is
A1 pi s l = pi * sqrt(5) (2 pi r) = 2(pi^2)sqrt(5)
The curved surface has an area of
A2 = 2 pi r h = 2pi (1)(11) =22pi
The base has an area of
A3 = pi r^2 = pi
Total area = A1+A2+A3 = 2sqrt(5) (pi^2) + 22pi + pi
= 2sqrt(5) pi^2 + 23pi

Consider the given function. Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry of the function.
Answer:
Following are the solution to the gvien question:
Step-by-step explanation:
Let the quadratic equation is:
[tex]\to h(x) = (x + 1)^2 - 4[/tex]
vertex is:
[tex]\to h(x) = a(x -h)^2 + k[/tex]
(h) = axis of symmetry
(h,k) = vertex.
By using the given equation:
[tex]h(x) = (x - (-1))^2 - 4[/tex]
Hence,
[tex]h = -1 \\\\ k = -4[/tex]
line of symmetry [tex]x = -1[/tex]
vertex is [tex](h,k) = (-1,-4)[/tex]
finding the x intercept:
[tex](x + 1)^2 = 4\\\\\sqrt{(x + 1)^2} = \sqrt{4}\\\\x + 1 = \pm 2\\\\x = 2-1 \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-2 -1\\\\x = 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-3\\\\[/tex]
x -intercepts -3,1
Calculating the y-intercept when x = 0 putting into the real equation:
[tex]h(x) = (0 +1)^2 - 4 \\\\y = 1 - 4\\\\y = -3[/tex]
