What's the rate of (x-1)*6-100
Can someone help me, please?
Answer: The slope is 2/3.
Step-by-step explanation: From (-1,6) to (-7,-3), the x goes up 6, and the y goes down 9. This makes the fraction -6/9. This would reduce to -2/3, but the direction the slop is headed is upwards to the right, meaning it's a positive slope.

Write a summary of how to get the area of a parallelogram.
Answer:
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.

The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?
Answer:
Yes, this is a right triangle.
Step-by-step explanation:
If you look more closely, you can notice that it is a 3-4-5 Pythagorean triple and it was multiplied by 3 to get 9-12-15.
Or you can do it using the Pythagorean Theorem directly:
9^2 + 12^2 = 15^2
and that is true.
Answer:
yes it is.
Step-by-step explanation:
pythagorean theorem. A^2 + B^2 = C^2
Ex 9^2 + 12^2 = 15^2
The green triangle is a dilation of the red triangle with a scale factor of s=13 and the center of dilation is at the point (4,2)
What are the coordinates of Point C'? C'(___,____)
What are the coordinates of Point A? A(____,____)
Given:
Scale factor [tex]s=\dfrac{1}{3}[/tex]
Center of dilation = (4,2)
To find:
The coordinates of the points C' and A.
Solution:
We know that, if a figure is dilated with a scale factor k and the center of dilation is at the point (a,b), then
[tex](x,y)\to (k(x-a)+a,k(y-b)+b)[/tex]
The scale factor is [tex]\dfrac{1}{3}[/tex] and the center of dilation is at (4,2).
[tex](x,y)\to (\dfrac{1}{3}(x-4)+4,\dfrac{1}{3}(y-2)+2)[/tex] ...(i)
Suppose the vertices of red triangle are A(m,n), B(10,14) and C(-2,11).
Using rule (i), we get
[tex]C(-2,11)\to C'(\dfrac{1}{3}(-2-4)+4,\dfrac{1}{3}(11-2)+2)[/tex]
[tex]C(-2,11)\to C'(\dfrac{1}{3}(-6)+4,\dfrac{1}{3}(9)+2)[/tex]
[tex]C(-2,11)\to C'(-2+4,3+2)[/tex]
[tex]C(-2,11)\to C'(2,5)[/tex]
Hence, the coordinates of Point C' are C'(2,5).
Let us assume that point A is A(m,n).
Using rule (i), we get
[tex]A(m,n)\to A'(\dfrac{1}{3}(m-4)+4,\dfrac{1}{3}(n-2)+2)[/tex]
From the given figure it is clear that the image of point A is (8,4).
[tex]A'(\dfrac{1}{3}(m-4)+4,\dfrac{1}{3}(n-2)+2)=A'(8,4)[/tex]
On comparing both sides, we get
[tex]\dfrac{1}{3}(m-4)+4=8[/tex]
[tex]\dfrac{1}{3}(m-4)=8-4[/tex]
[tex](m-4)=3(4)[/tex]
[tex]m=12+4[/tex]
[tex]m=16[/tex]
And,
[tex]\dfrac{1}{3}(n-2)+2=4[/tex]
[tex]\dfrac{1}{3}(n-2)=4-2[/tex]
[tex](n-2)=3(2)[/tex]
[tex]n=6+2[/tex]
[tex]n=8[/tex]
Therefore, the coordinates of point A are (16,8).

The segments are both marked with a congruency mark.
If a = 2 and b = 3, then the value of (a^b + b^a)-1 is :
Answer:
[tex]16[/tex]
Step-by-step explanation:
Substituting [tex]a=2[/tex] and [tex]b=3[/tex] into [tex](a^{b}+b^{a})-1[/tex] gives us:
[tex](a^{b}+b^{a})-1[/tex]
[tex]=(2^{3} +3^{2})-1[/tex] (Substitute given values into expression)
[tex]=(8+9)-1[/tex] (Evaluate exponents)
[tex]=17-1[/tex] (Evaluate expression in parentheses)
[tex]=16[/tex] (Simplify)
Hope this helps!
Answer:
16
Step-by-step explanation:
Given
([tex]a^{b}[/tex] + [tex]b^{a}[/tex] ) - 1 ← substitute a = 2, b = 3
= (2³ + 3²) - 1
= (8 + 9) - 1
= 17 - 1
= 16
Hello im in 8th grade and I need to get my grades up so anyone know the answer to
-12 minus 12x = 36
work also needs to be shown if possible thank you
Answer:
x = 3
Step-by-step explanation:
12x = 36
simply 12 will go to the other side and switches to the opposite sign for example + will be -
× will br ÷
so 36 ÷ 12 =3
x = 3
5x+10=115 what is the value of x

and bottles of water.
a. Choose variables for the two unknown quantities in the problem and tell wha
each variable represents.
b. Use the variables you chose in problem 3a to write an equation for the amour
of money Mr. Lincoln spends.
c. Use the variables you chose in problem 3a to write an equation for the numbe
of drinks Mr. Lincoln buys.
d. Solve the system of equations. How many packs of juice boxes and how many
packs of water does Mr. Lincoln buy? Show your work.
SOLUTION
my
Answer:
5x + 3y = 95
8x + 6y = 170
x = 10 ; y = 15
Step-by-step explanation:
Let :
x = pack of juice boxes
y = pack of water bottles
Pack of juice box = $5
Pack of water bottles = $3
Amount of money spent :
5x + 3y = $95
Number of drinks purchased :
8x + 6y = 170
Using both equations ;
5x + 3y = 95 - - - (1)
8x + 6y = 170 - - - (2)
Multiply (1) by 6 and (2) by 3
30x + 18y = 570
24x + 18y = 510
Subtract :
6x = 60
x = 60 / 6
x = 10
Put x = 10 in (1)
5(10) + 3y = 95
50 + 3y = 95
3y = 95 - 50
3y = 45
y = 45 / 3
y = 15
x = 10 ; y = 15

sally purchased 24 pencils 1/8 of the pencils are blue 1/6 of the pencils are red how many pencils are either red or blue
A. 17
B.14
C.7
D.4
Answer:
4
Step-by-step explanation:
Because the common multiple of 6 and 8 is 24 which is the amount of pencils.
1/8 x 3 equals 24 (3 because 3 times 8 gives 24)
1/6 x 4 equals 24 (4 because 4 times 6 gives 24)
A super train traveled 420 miles in 3 hours. If it maintain the same speed, how far could the train travel in 16 hours?
Answer:
We conclude that the train can travel 2240 miles in 16 hours.
Step-by-step explanation:
Given that a super train traveled 420 miles in 3 hours.
Distance covered = 420 milesTime taken = 3 hoursStep 1 of 2
Determine distance per hour
Important Tip:
The distance per hour can be determined by dividing the distance covered by the time taken.Distance per hour = Distance Covered / Time taken
= 420 / 3
= 140 miles per hour
Step 2 of 2
Determine the distance traveled in 16 hours
We already know that a super train travels 140 miles per hour. In other words, the speed of the super train is 140 miles per hour.
Important Tip:
To determine the distance covered in 16 hours, all we need to do is to multiply the distance covered per hour i.e. 140 with the total number of hours i.e. 16.Distance traveled in 16 hours = Distance per hour × 16
= 140 × 16
= 2240 miles
Conclusion:
Therefore, we conclude that the train can travel 2240 miles in 16 hours.
