serg [7]3 years ago
6 0

x-3y=-7\qquad|-x\\\\-3y=-x-7\qquad|:(-3)\\\\y=\dfrac{x+7}{3}

<em>We choose any values of x and calculate the value of y</em>

for\ x=-4\to y=\dfrac{-4+7}{3}=\dfrac{3}{3}=1\to(-4,\ 1)\\\\for\ x=-1\to y=\dfrac{-1+7}{3}=\dfrac{6}{3}=2\to(-1,\ 2)\\\\for\ x=2\to y=\dfrac{2+7}{3}=\dfrac{9}{3}=3\to(2,\ 3)

<h3>Answer:  (-4, 1), (-1, 2), (2, 3).</h3>

What is 2x times x squared?
tresset_1 [31]

We want to multiply the monomial 2x by the monomial 2x^2.

Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: (a^m)(a^n)=a^{m+n}, (x^2)(x^4)=x^{2+4}=x^6. Also, is worth pointing out that the exponent of a variable with no exponent is 1: x=x^1.

Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so x=1x. Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.

Let's apply all of that to our multiplication:

(2x)(x^2)=(2x^1)(1x^2)=2*1x^{1+2}=2x^3

We can conclude that 2x times x squared is 2x cubed.

Please help me to answer this question
ikadub [295]
(180-x) + 18 + 30 + x/2 = 180

=> 180 + 48 - x + x/2 = 180

=> -x/2 + 48 = 0

=> x/2 = 48

=> x = 48×2 = 96°

What is the GCF of 24a 3 b and 36ab 2?
Orlov [11]
Not sure if the 2 at the end is part of it all because with it the GCF can only be 1 

but,

the GCF of  24a, 3b and 36ab is 3.
