Answer:
8/13
Step-by-step explanation:
(−4,−4);(9,4)
(x1,y1)=(−4,−4)
(x2,y2)=(9,4)
Use the slope formula:
m=
y2−y1
x2−x1
=
4−−4
9−−4
The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
3(y - ¹/₇) - y = 4(2 - y)
3(y) + 3(⁻¹/₇) - y = 4(2) + 4(-y)
3y + (⁻³/₇) - y = 8 + (-4y)
3y - ³/₇ - y = 8 - 4y
3y - y - ³/₇ = 8 - 4y
2y - ³/₇ = 8 - 4y
<u>+ 4y + 4y</u>
6y - ³/₇ = 8
<u> + ³/₇ + ³/₇
</u> <u>6y</u> = <u>8³/₇
</u> 6 6<u>
</u> y = 1¹⁷/₄₂
Answer: A=πr²
A=3.14(1.6inch)² r=d/2⇒3.2/2⇒1.6
A=3.14×2.56in²
A=8.0384in²
A≈8.04
now circumference,
C=2πr
C=2×3.14×1.6in
C=10.048in
C≈10.05
