Need help with these last two questions, tysm if you do :D

Mathematics
1 answer:

Answer:

D.

A. x ≤ 1

Step-by-step explanation:

Well for the first question we need to simplify the inequality.

4x + 3 < x - 6

-x to both sides

3x + 3 < -6

-3 to both sides

3x < -9

Divide 3

x < -3

So if x is less than -3 than it goes to the left starting at -3.

So D. is the answer.

So to solve the floowing inequality we simplify, distribute, and combine like terms.

3(2x - 5) + 3 ≤ -2(x + 2)

6x - 15 + 3 ≤ -2x -4

6x -12 ≤ -2x - 4

8x - 12 ≤ -4

+12

8x ≤ 8

8/8

x ≤ 1

Hence the answer is A. x ≤ 1

Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the triangle. HELP PLE
sashaice [31]

Answer:

0.02

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the triangle is equal to divide the area of the triangle by the area of rectangle

Let

x-----> the area of triangle

y----> the area of rectangle

P -----> the probability

P=x/y

<em>Find the area of triangle (x)</em>

A=(1/2)(5)(2)=5\ in^{2}

<em>Find the area of rectangle (y)</em>

A=18*12=216\ in^{2}

<em>Find the probability P</em>

P=5/216=0.02
