Answer:
units or 14.2 units (rounded to the nearest tenth)
Step-by-step explanation:
To find the distance between a pair of two points, use the distance formula
. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:
So, as an exact answer, the distance is
units.
(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)
Hello!
To calculate how much 3 cakes would cost, we must first find the cost of each individual cake.
To do this, we must divide the cost of 8 cakes by 8 cakes.
4.00 ÷ 8 = 0.5
This means that each individual cake costs $0.50. Multiply this by 3 to find the cost of 3 cakes.
0.50 × 3 = 1.50
Therefore, 3 cakes would cost $1.50.
Twice, sum. and is are the important words.
No intervals are showing, but here is how to solve this equation.
0.35x - 4.8 < 5.2 - 0.9x
Add 4.8 to both sides
0.35x < 10 - 0.9x
add 0.9x to both sides
1.25x < 10
divide both sides by 1.25
x < 8
Interval Notation:
If we graphed this on a number line, x goes toward negative infinity.
Answer: (-∞, 8)
Hope this helps! :)
The answer is definitely 1
