Answer:
-1.5
Step-by-step explanation:
The product of slopes of two perpendicular lines = -1
If line one has a slope of 2/3;
Let line two, perpendicular to line one, has a slope of a
2/3 × a = -1
a = -1 ÷ 2/3 = -3/2 = -1.5

Thank you
Answer:
IMS aka infintely many solutions :)
Step-by-step explanation:
2x+4(x-6)=3(2x-8)
distribute
2x+4x-24=6x-24
combine like terms
6x-24=6x-24
carry across equal sign
6x=6x
carry across equal sign
0=0 aka IMS
Answer:
No solutions I think
Step-by-step explanation:
2x + 4(x -6) = 3(2x -8)
2x + 4x -24 = 6x - 24
6x - 24 = 6x - 24
-6x +24 -6x +24
0 = 0

what coordinate expression represents the coordinates of any point after dilation by any scale factor, a?
Answer:
(x,y) → (ax,ay) .
Step-by-step explanation:
A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.
If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).
So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of a:
(x,y) → (ax,ay) .
Answer:
[tex]\huge\boxed{(ax, ay)}[/tex]
Step-by-step explanation:
In order to dilate the coordinates of a point, we want to make it [tex]a[/tex] times bigger. In order to do this, we can multiply the x and y values by our scale factor, a. This is called mapping. What it does is it basically multiplied our points by a specific number so that we end up with a figure that is [tex]a[/tex] (the scale factor) times bigger than the original.
So in order to make an expression for this, we multiply the x and y coordinates by a. So we have ax and ay.
Hope this helped!
Rewrite (x – 3) (x + 5) + (x – 3) (2x – 1) as the product of two binomials.
(x - 3)(x + 5) + (x - 3)(2x - 1)
We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1
(x - 3)(3x + 4) is the final answer.
Please answer! Thank you in advanced
Answer: D
Step-by-step explanation:
To solve this problem, let's go through each pair to see if they are perpendicular lines.
A. Incorrect
These are parallel lines. We know this because they have the same slope and different y-intercept.
----------------------------------------------------------------------------------------------------
B. Incorrect
These are not perpendicular lines. The slope is [tex]-\frac{1}{m}[/tex]. The slope of the pair doesn't match this property.
----------------------------------------------------------------------------------------------------
C. Incorrect
These are not perpendicular lines. The slope is [tex]-\frac{1}{m}[/tex]. The slope of the pair doesn't match this property.
----------------------------------------------------------------------------------------------------
D. Correct
These are perpendicular lines. The slope is [tex]-\frac{1}{m}[/tex]. The slope of the pair matches this property.
----------------------------------------------------------------------------------------------------
E. Incorrect
These are not perpendicular lines. You can see that y=5 and x=5. The slope is [tex]-\frac{1}{m}[/tex]. The slope of the pair doesn't match this property.

Frankie buys six and twelve fifteenths pounds of cherries and four and four sixths pounds of grapes. How many pounds of fruit did she buy in total?
A. ten and forty two ninetieths pounds
b. ten and sixteen twenty firsts pounds
c. eleven and forty two ninetieths pounds
d. eleven and sixteen twenty firsts pounds
Answer:
the answer is C: eleven and forty two ninetieths pounds
Step-by-step explanation:
The total number of pounds of fruit that Frankie bought is 11 + 42/90 pounds, which is the same as option (C), eleven and forty-two ninetieth pounds.
What is the addition operation?The addition operation in mathematics adds values on each side of the operator.
For example 4 + 2 = 6
To find the total number of pounds of fruit that Frankie bought. Since both amounts are already given in pounds, we don't need to convert them.
Next, we need to add the two amounts together. Six and twelve fifteenth pounds can be written as 6 + 12/15 pounds, and four and four-sixths pounds can be written as 4 + 4/6 pounds. Adding these two amounts together, we get 6 + 12/15 + 4 + 4/6 pounds = 11 + 42/90 pounds.
Therefore, the total number of pounds of fruit that Frankie bought is 11 + 42/90 pounds, which is the same as option (C), eleven and forty-two ninetieth pounds.

Step-by-step explanation:
A $2 postal money order actually costs $2.15
$10.00 ÷ $2.15 = 4.65
Since you can't purchase a fraction of a money order, the most you can buy is 4
4 money orders will cost $2.15 × 4 = $8.60
The change from $10.00 will be $10.00 - $8.60 = $1.40
m-8=33 can you plz help me do this
Answer:
41
Step-by-step explanation:
m-8=33
Combine like terms by moving 8 to the other side
m=33+8
m=41
I hope this helps! Please comment if you have any questions.
Answer:
M = 41
Step-by-step explanation:
This question is a basic one. Don't let the letter freak you out haha. All you need to do for something like this is find out what minus 8 is 33. An easy way we can do this is just add 8 to 33. 33 + 8 = 41.
41 - 8 = 33.
Your answer is 41.

the price of gravel is $24 for every 3/8 ton. kate wants to know the price of 2 tons of gravel
Answer:
$128
Step-by-step explanation:
your looking for 16/8, divide 16 by 3, leaving you with 5.333...
now times that by $24, and you have your answer hope this helps
The price of 2 tons of gravel is $128.
Given:
The price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.
To find:
The price of 2 tons of gravel.
Explanation:
Let [tex]x[/tex] be the price of 1 ton of gravel.
Then the price of [tex]\dfrac{3}{8}[/tex] ton is [tex]\dfrac{3}{8}x[/tex] and the price of 2 tons of gravel is [tex]2x[/tex].
It is given that the price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.
[tex]\dfrac{3}{8}x=24[/tex]
[tex]x=\dfrac{8}{3}\times 24[/tex]
[tex]x=8\times 8[/tex]
[tex]x=64[/tex]
Now, the price of 2 tons of gravel is:
[tex]2x=2(64)[/tex]
[tex]2x=128[/tex]
Therefore, the price of 2 tons of gravel is $128.

Leslie ran a total of 8 miles over the course of 4 track practices. How many miles would Leslie have ran after 5 track practices? Solve using unit rate.
Answer:
10 miles
Step-by-step explanation:
Find how much she runs during one track practice by dividing 8 by 4. This gives you the equation 2x, with x being the number of track practices.
Answer: 10 miles after 5 track practices.
Step-by-step explanation: Lets find the unit rate of this problem. Remember that unit rate means the denominator will always have a 1.
8/4 converted to a unit rate is 2/1
The unit rate is 2 miles per every 1 track practice.
We can use the unit rate to solve how many miles Leslie would have ran after 5 track practices.
2/1 x 5 = 10/5
So, Leslie would have ran 10 miles after 5 track practices.
Which two numbers of the given data set have the same absolute value? Explain your answer in full sentences.
-5, 5, -3, 8
pls help. ;)
Answer:
The answer is -5 and 5 because when you do absolute value if there is a negative number then it turns into a positive number. Negatives will always turn out as positives when doing absolute value. :)
Step-by-step explanation:
Answer: the two numbers that have the same absolute value is -5, and 5.
Step-by-step explanation:
Absolute will just make any negatives to positive.
So, the absolute value of -5 is 5, or the absolute value of -3, is 3.
If it's already positive, then nothing happens; it stays the same
So, the absolute value of 8 is 8, nothing is changed.
