What are the intercepts of -4x plus 6y-5z equals 60?
-4x + 6y - 5z = 60At the x-intercept, 'y' and 'z' are zero:-4x = 60 ===> x = -15At the y-intercept, 'x' and 'z' are zero:6y = 60 ===> y = 10At the z-intercept, 'x' and 'y' are zero:-5z = 60 ===> z = -12
How would you write the product of a number z and 4 as a variable expression?
4xz=16
What number multiplied by itself 3 times equals 1728?
It is: 12*12*12 = 1728
What is z increased by 12 as a expression?
z + 12
If five numbers average 20 and by taking out one number the average becomes 15 what it the value of the missing number?
This question can be rephrased as, "If (v+w+x+y+z)/5=20, then for what value of z does (v+w+x+y)/4=15?". Thus, z is "the missing number." Let's solve for v+w+x+y in both equations. In the first equation, v+w+x+y=(20)(5)-z=100-z. In the second equation, v+w+x+y=(15)(4)=60. So 100-z=60. z=40. That's it! The missing number is 40!
Solve for z z over 12 equals -60?

6393600 74 * 24 = number of hours or Y Y * 60 = number of minutes or X X * 60 = number of seconds or Z Z = 6393600
When a number is multiplied by a number and that same number again what is its name?
You could say it's "the product of number A and number B squared".For example,Let's call our two unknown numbers y and z.You're asking "what is y*z*z ?"Any number times itself is the number squared, so y*z*z = y*z^2Product means multiply, so y*z^2 is the product of y and z squared.Be careful though, as the sentence could be interpreted as (y*z)^2 rather than y*z^2. Perhaps it's even better to say "the product of y and the square of z".

What is the symbol for 12p 10e 12n?
The symbol for an element is typically written as [A-Z][a-z][number], where A is the element's atomic number, Z is the element's chemical symbol, and the number represents the sum of protons and neutrons (called mass number). So, for 12 protons, 10 electrons, and 12 neutrons, the symbol would be Mg.
What are the cube roots of an imaginary number in trigonometric form?
z = y i where y is a real number 1: z^(1/3) = y^(1/3) (cos(30 deg) + i sin(30 deg)) 2: z^(1/3) = y^(1/3) (-sin(60 deg) + i cos(60 deg)) 3: z^(1/3) = y^(1/3) (- i)
7 times z reduced by a third of the product?
7 times z reduced by a third of the product
How can you write the product of a number and a sum as the sum of two products?
x*(y+z) = x*y + x*z This is the distributive property of multiplication over addition.
What half the product of x and y?
(x+y)/2
