The value of A for the two graphs will be 9.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
The two equations are Ax+6y = 12 and 2x−3y = 4. The value of A will be calculated as,
2x−3y = 4
y = 2/3x - 4/3
Ax+6y = 12
y = -A/6x +2
The slope of one graph will be inverse and the opposite to the other graph for the line to be perpendicular,
-3 / 2 = -A / 6
A = 9

7.5 miles in 1/4 hour
What is the constant speed
Will be marked BRAINLIEST
Answer:
I believe the answer is 30 miles per hour.
Step-by-step explanation:
Ok, I may be dangerously very super-duper wrong about this question, but even still, please don't hate me!!!!!!
So to find the constant speed of a moving object you divide distance by the time:
7.5 divided by 1/4 = 1.875
Since this answer doesn't really make since for the question, I decided to change 1/4 to a decimal number, which is 0.25, to see if this makes more since:
7.5 divided be 0.25 = 30
I believe the answer is 30 miles per hour.
Also, I would greatly appreciate brainly if I'm correct!!!!!!!

Answer:
<B = 110°
Step-by-step explanation:
The interior angles formed by the sides of pentagon sum up to 540°.
So <A + <B + <C + <D + <E = 540°
130° + (x - 5)° + (x + 30)° + 75° + (x - 35)° = 540°
3x + 130 + 30 + 75 - 5 - 35 = 540
3x + 195 = 540
3x = 345
x = 115°
<A = 130°
<B = x - 5 = 115 - 5 = 110°
<C = x + 30 = 115 +30 = 145°
<D = 75°
<E = x - 35 = 115 - 35 = 80°
Hope it helps......

CBA should be hmm 90 degrees I think
Then you should be able to calculate
it's so easy
Step-by-step explanation:
Answer:

If you place a 34-foot ladder against the top of a building and the bottom of the ladder is 25 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answer:
23.0 ft to nearest 1./0.
Step-by-step explanation:
By Pythagoras:
34^2 = h^2 + 25^2 where h = the height of the building
h^2 = 34^2 - 25^2 = 531
h = 23.04 ft.

Everytime your X goes up by 1, your Y goes up by 4
making the space between 6 and 14 = 10
the exponential factor equation would look something like this
g(x)=3^x
meaning every time x goes up by 1, your exponential factor gets multiplied by 3, making 14y have an exponential factor of 1.

Yall what is 10+9x please help thanks shawty
Answer:
19x I believe
Step-by-step explanation:
Added 10 and 9, left the x
Answer:
10+9x can't be combined to make a number
Step-by-step explanation:
This is because the 10 doesn't have the variable x so we can't combine them together
If the 10 had an x beside it, it would've become 19x, but it doesn't so it stays as is

A cylinder has a height of 13 feet and a radius of 11 feet. What is its volume? Use a ~ 3.14
and round your answer to the nearest hundredth.
Answer:
4939.22 feet cubed.
Step-by-step explanation:
The formula for the volume of a cylinder is V=3.14*r^2*h
First we square the raidus, which is 11 in this problem. 11 squared is 121.
Next we multiply everything together.
3.14*121 is 379.94. Then, 379.94 * the height, which is 13, is 4939.22.
Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22

A machine can produce a maximum of 600 parts per day. Yesterday, it produced 75 % of its maximum capacity. How many parts did the machine produce yesterday?
Answer:
450
Step-by-step explanation:
here is a fast way:
1- 75% = 75/100 = 3/4
2- 600 × (3/4) = 450
Answer:
450
Step-by-step explanation:
Step 1: Convert 75% to fraction
[tex]\frac{75}{100} = \frac{3}{4}[/tex]
[tex]=\frac{3}{4}\times \:600[/tex]
Step 2: Convert 600 to a fraction
[tex]600=\frac{600}{1}[/tex]
Step 3: Set it up
[tex]=\frac{3}{4}\times \frac{600}{1}[/tex]
Step 4: Cross Divide
[tex]600 \div 4 = 150\\3 \div 1 = 3[/tex]
Step 5: Multiply the results
[tex]150 \times 3 = 450[/tex]
Therefore, the machine produced 450 parts yesterday
