92

given 2a² + 5b²

substitute given values for a and b into the expression

2(- 6)² + 5(2)² = (2 × 36 ) + (5 × 4) = 72 + 20 = 92

If Tom has 3 different sweaters, and 5 different pairs of pants, how many different combinations could he wear?
Vladimir [108]
Check the tree diagram in the picture.

Tom could pick Pants 1 (P1), then Sweater 1, 2 or 3. So 3 combinations

Similarly if we picked P2, P3, P4 or P5 we would have 3 combinations per each.

In total we have 5*3=15 different combinations.

Which graph represents the solution to the system of inequalities? x + y ≥ 4 2x + 3y < 12
viktelen [127]
There are two inequality equations to be graphed:

<span>x + y ≥ 4
2x + 3y < 12

For the first step, let's disregard the inequality symbols and take it like any conventional algebraic equation. This is to be able to graph the lines on a Cartesian planes first.

For the first equation, x+y=4. To find the x- and y-intercepts, let the other variable be 0. For example,
x-intercept:
x+0=4
x=4
y-intercept:
0+y=4
y=4
Therefore, you can graph the equation line by plotting the intercepts (4,0) and (0,4) and connecting them together. The same thing is done to the second equation:
x-intercept: 
</span>2x + 0 = 12
x=12/2=6
y-intercept:
0 + 3y =12
y= 12/3 = 4
Therefore, you can graph the equation line by plotting the intercepts (6,0) and (0,4) and connecting them together. The graph is shown in the left side of the picture.

The next step would be testing the inequalities. Let's choose a point that does not coincide with the lines. That point could be (-5,-1). 

x + y ≥ 4
-5 + -1 ≥4
-6 ≥ 4 --> this is not true. Thus, the solution of the graph must not include the area of this point. It includes everything to the right of the line denoted by the blue-shaded region.

2x + 3y < 12
2(-5) + 3(-1) <12
-13 < 12 ---> this is true. Thus, the solution would include this point. That includes all points to the left of the orange line denoted by the orange-shaded the region.

The region where blue and orange overlap is the solution of the system of equations, denoted by the green-shaded region.
