Answer:
3
Step-by-step explanation:
√7a-10 - √2a+5=0
√7a-10 = √2a+5
7a-10 = 2a+5
5a = 15
a = 3

I need to know if it is maximum or minimum , the axis of symmetry , the vertex , domain , range
Answer:
i honestly have no idea
Step-by-step explanation:
Answer:
The coefficient of x^2 is positive (here it is 1) so we have a minimum.
Rearrange it to the form (x-a)^2 + b:
(x+2)^2 - 4 - 5 = (x+2)^2-9
This means the minimum, or vertex, is at (-2,-9)
Parabolas are symmetrical horizontally, so the axis of symmetry is the vertical line at the minimum, which is x = -2
The domain is all numbers
The range is y >= -9

A rectangular field 50 metres wide and x metres long required 260 metres of fencing
Answer:
x=80
Step-by-step explanation:
im going to assume this is perimeter.
50+50=100
260-100=160
160÷2=80
Answer:
5.2 metres in length I think
Step-by-step explanation:
you didnt exactly put a question, but this seems like a problem where you have to divided the volume by the width to find the length, so 260 divided by 50 is 5.2. I apologize if it is wrong, like I said, there wasn't a question so i was confused.

Triangle RST has vertices R(–1, 1), S(3, 1), and T(3, –4). What
are the coordinates of the image of RST after a translation 4 units to the left and 2 units down?
Answer:
R'(-5, -1) S'(-1, -1) T'(-1,-6)
Step-by-step explanation:
because the triangle is moving to the left, you subtract the number of units from the x coordinates of each vertex of the triangle. becasue the triangle is moving down, you subtract the number of units moved down from the y coordinates of each vertex.
Derwin used 6 gallons of paint to paint two rooms. He used 4 gallons to paint one of the rooms. The equation g + 4 = 6 can be used to find the number of gallons g he used to paint The other room. How many gallons of paint did Derwin use to paint the other room?
Answer:
He used 2 gallons to paint the other room.
Step-by-step explanation:
g=2
Because 2+4=6
If you subtract 4 from 6 it equals 2.
Hopefully it helps.
PLEASE HELP ME QUICKLY!! The graph shows the number of eggs a farmer collected from each chicken pen one morning. How many more eggs were collected from pen 3 than from pen 2 & 5? (Each egg = 5 eggs)
Answer:
Pen 2 = 5 eggs
Pen 3 = 25 eggs
Pen 5 = 10 eggs
It is asking how many MORE eggs does pen 3 have from BOTH pens 2 and 5. Add 2 and 5. But remember one egg = 5 eggs so as stated in the beginning pen 2 has 1 egg which equals 5 eggs and pen 5 has 2 eggs which equals 10.
5 + 10 is?
15, exactly. So how many more eggs does pen 3 have? 15 + one more egg is 20 and pen 3 has 25 which is more than 20 so let’s add another egg which again equals 5.
Now we have 25 eggs, the exact amount pen 3 has. The answer is 2 more eggs/10 more eggs.

Mr. Dyer left a $12.60 tip at a restaurant. This represented 18% of his family’s dinner bill. What was the amount of the family’s dinner bill?
Answer:
$70
Step-by-step explanation:
$12.60 / .18 = $70
I hope this is right, but I am thinking it is since you have to multiply by .18 to get the tip value.

Write an equation and solve.
8 less than a number is 24
8 less than a number can be written as
x-8
when you see the word is you should think of = sign
so the equation will be x-8=24
Now solve adding 8 to both sides.
x=24+8
x=32
Answer:
a-8=24
Step-by-step explanation:
Answer is 32. add 8 to other side, making it 32
