If anyone can help with this ill mark Brainly

Mathematics
1 answer:
Natalka [10]3 years ago
6 0

Answer:

In this case, we can do substitution.

Step-by-step explanation:

For the first one, (s - t)(x) = ((x - 5) - 4x^2)(x) = x^2 - 21x

For the second one, (s*t)(x) = ((x - 5) *4x^2)(x) = 4x^4 - 20x^3

And for the last one,  (s+t)(-2) = ((x - 5) + 4x^2)(-2) = -8x^2 - 2x + 10

Hope your happy with the answer :)

<span>We have the number 81 as the largest perfect square in the range of the statement.
Since we have it as the largest square, then its largest possible modulus of "x" will be when </span>x^2 = 81<span>, that is, when </span>| x | = 9<span>.
Since it is the largest possible module, the rightmost number of the "0" in the line of integers, with the largest number being x = 9 and the leftmost number of the "0" in the line of integers, , Will be </span>x = - 9<span> 

Therefore, the difference requested in the statement is:
</span>v = 9 - (- 9) \longrightarrow v = 9+9 \longrightarrow \boxed{\boxed{v = 18}}

How do i graph -7x-2y=-21???
ExtremeBDS [4]

Answer:

-7/2 is the slope. -10.5 is your starting point on the y-axis. You go from -10.5, up 7 and over to the left 2 times because it's negative.

Step-by-step explanation:

-7x-2y=-21

-2y=7x-21

y=-7/2x-21/2

y=-7/2x-10.5

Hope this helps!
