Which expression is equivalent to 64y18 – 1000z6?

natta225 [31]

Answer:

$(4y^{6})^{3}-(10z^{2})^{3}$

Step-by-step explanation:

we have

$64y^{18}-1000z^{6}$

we know that

$64=4^{3}$

$y^{18}=(y^{6})^{3}$

$1000=10^{3}$

$z^{6}=(z^{2})^{3}$

Substitute the values in the expression

$(4^{3})((y^{6})^{3})-(10^{3})((z^{2})^{3})$

$(4y^{6})^{3}-(10z^{2})^{3}$

Please help me!! This is math 7th grade

Answer:

14) false

15) false

Step-by-step explanation:

14) 120% of a positive whole number is always greater than the number. If the number is 1, 120% of it would give us 1.2 which is greater than 1. However if the number is a negative whole number, 120% of it would give us a smaller number. Let's try -1. 120% of -1 would give us -1.2, which is smaller than -1. Hence the statement is false.

15) 0.5% of a number is 0.5/100 of the number so we should multiply the number by 5/1000. 5/100 is only 5% of the number. Hence the statement is also false.

What is the difference between no solution and no real solution? When do you get multiple solutions? This is for solving absolut

Dmitriy789 [7]

No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinitesolutions would mean that any value for the variable would make the equation true.No Solution Equations.

In other words, it "discriminates" between the possible solutions. The discriminant is the expression found under the square root part of the quadratic formula (that is, . The value of tells how many solutions, roots, or x-intercepts the quadratic equation will have. If , there are two real solutions.
