Find r :
C=2πr
280=2(3.14)r
r=280/2(3.14)
r=44.6cm
find area :
A=πr²
A=3.14(44.6)²
A=6246 cm²
Answer : 4)6,246
Your equation states y = 4(-1) + 3
Since the parentheses touch the number 4 which means you multiply, we will start with that first.
4 × -1 or 4(-1) (it means the same thing) would be -4
Now let us combine the equation.
y = -4 + 3
The addition property is included now,
-4 + 3 = -1
Therefore, your answer would be y = -1
Hope this helped! :D
Hello:<span>
the equation is : y = ax+b
the slope is a
</span><span>3x-4y=5.....
</span><span>4y = 3x-5
y = (3/4)x -5/4
the slope is (3/4)

Answer:
4.2 Solving x2-10x+25 = 0 by Completing The Square . This quadratic equation has one solution only. That's because adding zero is the same as subtracting zero.
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
subtract 3 from both sides
then divide by -2/3 from both sides and flip the inequality sign
then you get h > 36/2
Then h > 18
