Answer:
[tex]\frac43[/tex]
Step-by-step explanation:
Hello!
We can calculate slope using the formula [tex]\frac{Rise}{Run}[/tex].
Rise is the change in y between two pointsRun is the change in x between two pointsThe two points that I'm going to choose is (0,-4) and (3,0).
SlopeChange in y (-4 and 0) is 4Change in x (0 and 3) is 3Therefore, the slope of the line is [tex]\frac43[/tex].

Slope =
Slope =
Answer:
1. Slope = -2
2. Slope = ⁴/3
3. Slope = -3
4. Slope = 1
Step-by-step explanation:
1. Using two points on the line, (0, 0) and (-1, 2):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{2 - 0}{-1 - 0} = \frac{2}{-1} = -2 [/tex]
2. Using two points on the line, (0, 0) and (3, 4):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{4 - 0}{3 - 0} = \frac{4}{3} [/tex]
3. Using two points on the line, (0, 0) and (-1, 3):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{3 - 0}{-1 - 0} = \frac{3}{-1} = -3 [/tex]
4. Using two points on the line, (0, 0) and (2, 2):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{2 - 0}{2 - 0} = \frac{2}{2} = 1 [/tex]

Answer: R=5 D=10
Step-by-step explanation: If I am correct the radius is 5 while the diameter is 10. All you need to do is subtract 7 by 2 ( from the coordinates) giving you five. Now if you multiply 5 by 2 you get 10 which is the diameter. Hope this helps and best of luck.

Ajay reads aloud from a sports magazine. He comes across the measurement 0.63 kilometer. How should he read this measurement aloud? Explain how you know.
Answer:
"sixty-three hundredths of a Kilometer"
Step-by-step explanation:
Decimal measurements are read based on the place of their digits. In this case, Ajay would read this measurement as "sixty-three hundredths of a Kilometer". This is because the final digit of the decimal form measurement is in the "hundredths" position. One more to the right and it would be in the "thousandths" while one more to the left would be the "tenths"

==========================================================
Explanation:
We have AB = 3 and A'B' = 1.5; the ratio between the two segment lengths is (A'B')/(AB) = (1.5)/(3) = 1/2 = 0.5
Similarly,
(B'C')/(BC) = (3)/(6) = 1/2 = 0.5(C'E')/(CE) = (2.5)/(5) = 1/2 = 0.5You only need to pick one of these statements to be able to find the scale factor. The scale factor of 1/2 or 0.5 indicates that the image is half as small compared to the preimage. More specifically, each segment of the image is half as small compared to the corresponding segment on the preimage.
A'B' is half as small as ABB'C' is half as small as BCC'E' is half as small as CEA'E' is half as small as AEWe don't have numbers for AE and A'E', but the last statement above must be true because the dilation applies to all segment lengths.
The scale factor of this dilation in the given quadrilateral will be equal to 0.5 times.
What is a Polygon?A polygon is described in geometry as a compact, two-dimensional shape having three or more straight lines. Poly, which means "many," and gon, which means "angle," make up the Greek word "Polygon." Polygons of several kinds can be seen all around us.
As per the given information in the question,
AB = 3 and A'B' = 1.5;
Then, a ratio of the two segment lengths exists.,
(A'B')/(AB) = (1.5)/(3) = 1/2
(A'B')/(AB) = 0.5
In the similar way,
(B'C')/(BC) = (3)/(6) = 1/2
(B'C')/(BC) = 0.5
(C'E')/(CE) = (2.5)/(5) = 1/2
(C'E')/(CE) = 0.5
A'B' is half as small as AB, B'C' is half as small as BC, C'E' is half as small as CE, A'E' is half as small as AE.

PLEASE HELP THANKS!!
Answer: a) x = 5 b) x = 12
Step-by-step explanation: For each one you just do the inverse to get it on the other side of the equal sign. For example x + 3 = 8 would be like this :
1. x + 3 = 8
2. x + 3 - 3 = 8 -3
( + 3 - 3 cancels out)
3. x = 5
a. x + 3 = 8
x = 8 - 3
x = 5
b. x - 5 = 7
x = 7 + 5
x = 12

A standard showerhead dispenses 21 gallons of water in 30 mins. At this rate, how many gallons of water will a standard showerhead dispenses in 13 minutes.
Answer:
9.1 gallons of water.
Step-by-step explanation:
A standard showerhead dispenses 21 gallons of water in 30 mins. At this rate, how many gallons of water will a standard showerhead dispenses in 13 minutes?
30 minutes = 21 gallons
13 minutes = x gallons
Cross Multiply
30 minutes × x = 13 minutes × 21 gallons
x = 13 minutes × 21 gallons/30 minutes
x = 9.1 gallons of water
Therefore, a standard showerhead dispenses 9.1 gallons of water in 13 minutes.

Step-by-step explanation:
The cylindrical part
Area of the cylindrical part = Circumference of the circle * height
Area of the cylindrical part = pi * d * height
Area = 3.14 * 10 * 9
Area = 282.6
Lid
Area = pi * r^2
r = 5
Area = 3.14* 5^2 * 2
Area = 157
Total 439.6
I know this doesn't look right according to the diagram, but it is the only way that you can solve the question. That is, you must assume there are two lids, not one as the diagram suggests.

Answer:
(3x)(x-2)(x-1)
Step-by-step explanation:
First we can factor out the 3x from each and are then left with x^2-3x+2. Now we can go ahead and factor. Looking for two variables that multiply to become positive 2 and add to become negative 3, we get negative 2 and negative 1. We now know that both (x-1) and (x-2) are factors. We now have all three factors and we can multiply to check if we get the right answer, and we do.

How would you solve absolute value equations with "or" and "and"? Sometimes even with coefficients.
9514 1404 393
Explanation:
In general, a system of equations has a solution that satisfies all of the equations. That is, the solution set is the intersection (and) of the solution sets of the individual equations in the system. Equations involving the absolute value function are no different.
That being said, you need to consider the meaning of an equation involving the absolute value function.
The function itself is piecewise defined:
[tex]\displaystyle |x|=\left\{ {x, x\ge0} \atop {-x, x<0}} \right.[/tex]
So, any equation involving the absolute value function automatically resolves to two equations, each with its own condition on the function value.
__
Example 1:
|x+1| > 3
is equivalent to the two disjoint conditional equations ...
(x +1) > 3 and (x +1) ≥ 0 . . . . OR
-(x +1) > 3 and (x +1) < 0
the first of these has the solution x > 2; the second of these has the solution x < -4. The solution set of this equation is the OR of the two solution sets:
x < -4 or x > 2
__
Example 2:
|x +1| < 3
is equivalent to the two disjoint conditional equations ...
(x +1) < 3 and (x +1) ≥ 0 . . . . OR
-(x +1) < 3 and (x +1) < 0
The first of these has the solution -1 ≤ x < 2, and the second of these has the solution -4 < x < -1. Again, the solution set of this equation is the OR of the two solution sets. However, we find we can write that union as a single compound inequality:
-4 < x < 2
__
When an absolute value equation involves more than one absolute value function, then the equation will probably resolve into multiple equations, each defined on its own domain. Sometimes keeping those domains straight can be tedious.
Above, we have considered inequalities. If you have an equation, you need to consider that it will likely resolve to two equations. The solution set will be the OR of the solutions to those two equations.
Example 3:
|x +1| = 3
is equivalent to the two conditional equations ...
(x +1) = 3 and (x +1) ≥ 0 . . . . OR
-(x +1) = 3 and (x +1) < 0
The first of these has the solution x = 2; the second has the solution x = -4. The solution set is the OR of these two solutions:
x = -4 or x = 2
__
The "and" condition restricts the domain of each of the individual pieces of the equation. The "or" condition applies to the collection of solutions that may exist in each of those restricted domains.

Evaluate each expression for the given value of the variable : x+1/2 + 5x-3/10 when x=3
Answer:
18 1/5
Step-by-step explanation:
1. First, we can convert all the x's into 3's
Our Equation: 3+1/2 + 15 - 3/10
2. Now we know that 3+1/2 = 3 1/2
Our Equation : 3 1/2 + 15 - 3/10
3. Now, we can add 3 1/2 + 15
Our Equation: 18 1/2 - 3/10
4. Next we can convert 1/2 so that the denominator is 10 and we get 18 5/10
Our Equation: 18 5/10 - 3/10
5. Now, we can subtract 3/10 from 5/10
Our Answer: 18 2/10 or 18 1/5
Hope this Helps!!! :)
Let me know in the comments if the answer was perfect or if I should change anything!!! :)
Write the equation of the line that goes through (-2/3, 7/8) and is PARALLEL to 3x + 4y = 7
Answer:
6x+8y = 3
Step-by-step explanation:
we have 3x + 4y = 7
4y = -3x + 7
y = -3/4 x + 7/4
so slope is -3/4
2 parallel lines always have same slope
so the slope of our new line is -3/4
so y = -3/4 x + C
for c,
we have (x,y) = (-2/3,7/8)
7/8 = -3/4 * -2/3 + C
C = 3/8
so equation is
y = -3/4 x + 3/8
simplyfyig,
8y = -6x + 3
or, 6x+8y = 3
