To graph a linear equation,you can use the slope and y-intercept.

Locate the y-intercept on the graph and plot the point.

From this point, use the slope to find a second point and plot it.

Draw the line that connects the two points.

y= mx+b

b is y intercept

m is slope

Is this correct pls help

Lyrx [107]

Answer:

Volume of round cake pan = volume of cylinder

Volume of a cylinder = $\pi r^2h$ (where r is the radius and h is the height)

Radius = $\dfrac12$ diameter ⇒ $r=\dfrac72=3.5$

⇒ volume of round cake pan = $\pi \times 3.5^2 \times 2=24.5\pi$

= 76.97 in³ (nearest hundredth)

Volume of rectangular cake pan = volume of rectangular prism

volume of rectangular prism = $wlh$ (where w is the width, l is the length and h is the height)

⇒ volume of rectangular cake pan = 6 x 9 x 2 = 108 in³

As 108 > 76.97, the rectangular cake pan has a larger volume

A bag contains pennies and nickels. You are given the number of pennies in the bag

stira [4]

There are 3 nickels because if you use the ratio 6 to 1 you multiply 6 by 3 to get 18 pennies and you do the same with the one and that’s how I got 3 nickels.

Solve the equation 4 sin (x +30°) = 2 for 0 < x < 365

tatuchka [14]

$4 \sin(x + 30) = 2 \\ \sin(x + 30 ) = \frac{2}{4} \\ \sin(x + 30) = \frac{1}{2} \\ \sin(x + 30) = \sin(30) \\ x + 30 = 30 \\ x = 30 - 30 \\ x = 0$

Hence, x = 0°, 180° and 360° Ans
