One way to solve the system is to _____________ a variable.
Ivahew [28]

One way to solve the system is to <u>substitute</u> a variable.

<u>Explanation:</u>

One approach to solve an equation is by substitution of one variable. Right now, a condition for one factor, at that point substitute that arrangement in the other condition, and explain. All value(s) of the variable(s) that fulfills a condition, disparity, arrangement of conditions, or arrangement of imbalances.

The technique for tackling "by substitution" works by settling one of the conditions (you pick which one) for one of the factors (you pick which one), and afterward stopping this go into the other condition, "subbing" for the picked variable and fathoming for the other. At that point you back-explain for the principal variable.

You have a set of cards labeled 1-10. Set A is drawing an even card. Set B is drawing a 8 or higher.  What is the  P ( A ∪ B ) ?
creativ13 [48]

set A = {2, 4, 6, 8, 10}   (only even cards)

set B = {8, 9, 10}    (8 or higher)

( A ∩ B ) means the numbers which are common in both sets .

They both have 8 & 10 in common. 

So the answer is: P(A ∩ B) = {8,10}

Helena wrote the equation using point-slope form for the line that passes through the points (5, 1) and (3, 5). Analyze the step
viva [34]

Answer:

In step 2, she didn’t use an x and y from the same coordinate pair

Step-by-step explanation:

see the attached figure to better understand the problem

we have the points (5, 1) and (3, 5)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute

m=\frac{5-1}{3-5}

m=\frac{4}{-2}

m=-2

step 2

The equation of the line in point slope form is

y-y1=m(x-x1)

take the point (3,5)

m=-2

substitute

y-5=-2(x-3)

y-5=-2x+6

y=-2x+6+5

step 3

y=-2x+11

therefore

In step 2, she didn’t use an x and y from the same coordinate pair
