Answer:
The two numbers are 14 and 4
Step-by-step explanation:
Let x and y be the two numbers
x+y = 18
x-y = 10
Add the two equations
x+y = 18
x-y = 10
------------------
2x = 28
Divide by 2
2x/2 = 28/2
x = 14
Now find the other number
x+y =18
14+y = 18
y = 18-14
y=4
The two numbers are 14 and 4

What would increase the dissolution rate (the rate a solid dissolves) in a liquid?
Question 1 options:
decreasing the temperature of the solvent
grind the solvent into smaller pieces
stirring much more slowly
adding more solid to the liquid.
Answer and Step-by-step explanation:
The correct answer choice would be to grind the solvent into smaller pieces.
When the solid is in smaller pieces, it would take less time for the dissolver to dissolve the smaller bits, since the pieces are smaller and take up less volume for the dissolver to go through.
With a bigger solid, the dissolver would just chip away at the solid before eventually dissolving the solid, although this could take some time.

(9i)(i^2)(4i)
Pls awnser
Answer:
36
Step-by-step explanation:
We are dealing with imaginary numbers, which works differently than a normal problem.
Let's combine (9i) and (i^2) and create a multiplication problem,
9ii^2 * 4i
Multiply the constants :
[tex]36i^2ii[/tex]
We see 4 i's in this problem, add them all together :
[tex]36i^4[/tex]
4 i's are equal to 1, now multiply the constant :
[tex]36 * 1[/tex]

-4(x-3)^2+7=43 please show how you got your answers step by step pleaseee
Answer:
(x - 3)² = -9
Solution:
Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.
Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.
Answer:
x=3+3i, 3-3i
Step-by-step explanation:
-4(x-3)²+7=43
(x-3)(x-3)= x²-6x+9
-4(x²-6x+9)+7=43
-4x²+24x-36+7=43
-4x²+24x-29=43
-4x²+24x-72=0
-x²+6x-18=0
Quadratic formula: -b+√(b²-4ac) / 2a
-(-6)+√((-6)²-4(1)(18)) / 2(1)
6+√(36-72) /2
6+√(-36) / 2
x=6+6i / 2
x=3+3i, 3-3i

What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
Jason is 11 years old. His older brother is 5 years less than twice as old as he is.
let, Jason's older brother is x years old.
older brother x+5=2*11
x=17
again,
In 3 years Jason will be twice as old as his younger brother.
let, Jason's younger brother now is y years old.
young brother 2*(y+3)=11+3
