Answer:
No Solution
Step-by-step explanation:
OK first just remember PEMDAS which stands for
Parentheses Exponents Multiplication Division Addition Subtraction
so we do these things in order from left to right.
first i see some parentheses so lets take care of that, pay attention to this part
2(4x - 5)
lets do some distribution, we multiply the numbers in the parentheses by the number thats right outside of the parentheses
this becomes
8x-10
so now we have...
it is pretty easy from this point on
just add like terms. 5x plus 3x equals 8x. -10 - 2 equals -12.
now we have to do opposite calculations on both sides. for example, lets take the 8x to the right of the equal sign, and subtract 8x from both sides.
is this true? does this make sense? NO! so the answer is No Solution.
The linear inequality in standard form is: x + y < -2 or x + y + 2 < 0
<h3>How to Write a Linear Inequality?</h3>
To determine what sign to use, follow these rules:
- Use "<" or ">" when the boundary line is dotted or dashed.
- Use "<" or "≤" when the shaded area is under the boundary line (dotted or dashed).
- Use "≤" or "≥" when the boundary line is not dotted or dashed.
- Use ">" or "≥" when the shaded area is above the boundary line (dotted or dashed).
The graph given has the following features:
- It has a boundary line that is dotted/dashed.
- It has a shaded area that is under the boundary line.
- Thus, the inequality sign we would use is, "<".
Find the slope:
Slope (m)= rise/run = -(2 units) / (2 units).
Slope (m) = -1.
The y-intercept (b) = -2.
Substitute m = -1 and b = -2 into y < mx + b:
y < (-1)x + (-2)
y < -x - 2
Rewrite
x + y < -2
x + y + 2 < 0

Answer:
The first choice
Explanation:
Because there is a closed dot, you need to use either less than or equal to or greater than or equal to. And because it’s pointing to left and getting smaller, d is less than or equal to 5.
B
First you have to change 2 1/2 into 5/2
To multiply fractions use the method
Keep Change Flip
5/2 x 3/1 =15/2
Which simplifies to 7 1/2
