Help me plz quick my phone about to die
konstantin123 [22]
I'll do the first graph.

We can easily find the y intercept by inputting 0 for x.

y = -2(0) + 7
y = 7

The y-intercept is (0, 7)

To find the x intercept, isolate x.

y = -2x + 7
Add 2x to both sides.
2x + y = 7
Subtract y from both sides.
2x = -y + 7
Divide by 2 on both sides.
x = -1/2y + 3.5

Input 0 for y.

x = -1/2(0) + 3.5
x = 3.5

The x intercept is (3.5, 0)

Now try the rest own your own! :)

Find the surface area, to the nearest square centimeter, of a cylinder with diameter 6 cm and height 8 cm. A.48cm^2 B.452cm^2 C.
Black_prince [1.1K]

The right answer is Option C.

Step-by-step explanation:

Given,

Diameter = 6 cm

Radius = \frac{Diameter}{2}=\frac{6}{2}=3\ cm

Height = 8 cm

π = \frac{22}{7}

Surface area = 2πrh+2πr²

Surface area = 2*\frac{22}{7}*3*8+2*\frac{22}{7}*(3)^2\\

Surface area = \frac{1056}{7}+\frac{396}{7}=\frac{1056+396}{7}

Surface area = \frac{1452}{7}

Surface area = 207.4 cm²

Rounding off to nearest whole number

Surface area = 207 cm²

The surface area of cylinder is 207cm².

The right answer is Option C.

Keywords: surface area, cylinder
