Answer:
x < 4
Step-by-step explanation:
We have that: 1 + 2x < 9. Let's solve this as if the < sign was an = sign:
1 + 2x < 9
Isolate the variable:
2x < 9 - 1
2x < 8
Divide by 2:
x < 8/2
x < 4
The answer is x < 4.
Answer:10 in on left side 13 on top
Step-by-step explanation:
Answer: B. y = 1/2x - 1
Explanation:
I know someone else already answered, but I wanted to explain why the answer is B.
Consider an equation of a line in slope-intercept form: y = mx + b
Since the line intersects the y-axis at -1, that’s the y intercept, or b. We know the slope of the line is positive because it slopes upward from left to right. From each whole number solution point, the line goes up one and two to the right. Slope, represented by m, is “rise” over “run”, or the change in y over the change in x. This makes the slope 1/2.
I hope this helps.
Answer: 18 and 36
Step-by-step explanation:
The scale is 8m for every 2 in and the actual area is 144m2 so we need to covert that into inches. You divide 144 by 8 which = 18 and then multiply 18 x 2 which is equal to 36.
Marcus made a mistake in Step 2. 5/2.5 is 2 not 3.
-11 -(-42) A double negative makes a positive
-11 + 42
31
