A monomials are like polynomials and binomials, but it's just one term. By multiplying two monomials, you can rewrite the product as one monomial using the multiplication and exponent properties.

Answer:

x = 0, y = -3/2

Step-by-step explanation:

Solve the following system:

{-2 y + x = 3 | (equation 1)

{-8 y + 14 x = 12 | (equation 2)

Swap equation 1 with equation 2:

{14 x - 8 y = 12 | (equation 1)

{x - 2 y = 3 | (equation 2)

Subtract 1/14 × (equation 1) from equation 2:

{14 x - 8 y = 12 | (equation 1)

{0 x - (10 y)/7 = 15/7 | (equation 2)

Divide equation 1 by 2:

{7 x - 4 y = 6 | (equation 1)

{0 x - (10 y)/7 = 15/7 | (equation 2)

Multiply equation 2 by 7/5:

{7 x - 4 y = 6 | (equation 1)

{0 x - 2 y = 3 | (equation 2)

Divide equation 2 by -2:

{7 x - 4 y = 6 | (equation 1)

v0 x+y = -3/2 | (equation 2)

Add 4 × (equation 2) to equation 1:

{7 x+0 y = 0 | (equation 1)

{0 x+y = -3/2 | (equation 2)

Divide equation 1 by 7:

{x+0 y = 0 | (equation 1)

{0 x+y = -3/2 | (equation 2)

Collect results:

Answer: x = 0, y = -3/2

Answer:

x = 18°

m∠A = 110°

Step-by-step explanation:

Hello!

Angle A and Angle B are supplementary. Supplementary means they add up to 180°.

Step 1: Solve for x

We can add the two angles together and make it equal to 180° because they are supplementary.

x = 18°

Step 2: Solve for Angle A

Now that we know the value of x, we can plug it in for the equation of Angle A and solve for the measure of Angle A

Angle A = 110°

Answer:

4th quadrant

Step-by-step explanation:

Sec in Cartesian form is

[tex] \sec( \alpha ) = \frac{r}{x} [/tex]

In order for sec to be positive, we must have a positive x value so we must be in Quadrant 1 or quadrant 4.

cot is negative so that menas y must be negative so.

The quadrant that has a positive x value and negative y value is 4th quadrant.

Answer:

Whether you're teaching the meaning of fractions or fraction operations, visual models can help students connect fractions to what they already know. Division is an essential foundation for fractions. Once students can divide objects into equal groups, they can begin to grasp dividing a whole into equal parts.

Answer:

d; 151 bracelets

Step-by-step explanation:

to find this out we must divide each number of beads by their matching color amounts

1012 / 5 is 202.4 or 202

998 / 6 is 164.6... or 164

1057 / 7 is 151

151 is the least number out of all of these and in this case you can only make 151 bracelets or else you would run out of white

The dimension of her garden whose area is g² + 14g + 40 is (g + 10) and (g + 4).

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

Bailey writes the expression g² + 14g + 40

g² + 14g + 40

g² + 10g + 4g + 40

g (g + 10) + 4 (g + 10)

(g + 10)(g + 4)

The dimension of the factor is (g + 10) and (g + 4).
