Does the product of two real numbers with the same sign result in a positive? I think it does but not completely sure.

Answer:

Two negatives multiplied by each other equals positive, but a positive multiplied by a negative equal negative. A positive multiplied by a positive also obviously equals a positive.

Answer:

y+9=3/4(x-8)

Step-by-step explanation:

y-y1=m(x-x1)

y-(-9)=3/4(x-8)

What is the value for x

Step2247 [10]

this is an isosceles triangle... meaning that the two base angles will be equal.

180 - 38 = 142

142 / 2 = 71

x = 71

Answer:

x^2+14x+49 ( it could be polynomial because it has 3 terms and each term has a whole number and a coefficient)

Step-by-step explanation:

(x+7)^2

(x+7)(x+7)

x^2+7x+7x+49

x^2+14x+49

I am not sure it's a polynomial or not

Is (10,-10) a common solution for x-5>3 and -y>7?

fenix001 [56]

$\bf (\stackrel{x}{10}~~,~~\stackrel{y}{-10})
\\\\\\
\begin{cases}
x-5\ \textgreater \ 3\\
-y\ \textgreater \ 7
\end{cases}$

is it? let's check.

x-5>3 x = 10

(10) - 5 > 3

5 > 3 <----- hmmm is that really true? 5 is indeed greater than 3.

let's check the other condition, "y" being -10.

-y > 7 y = -10

-(-10) > 7

+10 > 7 <---- is 10 greater than 7 really? well, yes it is.

since the coordinates of 10, -10, provide a "true" value for each inequality, then 10,-10 is a solution.
