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

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 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
