GalinKa [24]

Y=mx + b
10x.5y.10=30
10x.5y=30-10
10x.5y=20
5y= -10x + 20
5/5 = -10/5(x) + 20/5
Y= -2x +4

I NEED HELP ASAP PLEASEEEE <br>Evaluate the expression for m = –38. <br>–23(m + 39) =

White raven [17]

Answer: -23

Step-by-step explanation:

Since we are given the value of m, all we have to do is to plug m into the expression and solve.

-23(-38+39) [parenthesis]

-23(1) [multiply]

-23

Now, we know that the expression is -23 when m=-38.

Answer:

The surface area of the cone $=238.64feet^2$

Step-by-step explanation:

The given figure is in the shape of a cone:

$Diameter=8 feet\\\\Radius=8/2=4 feet$

slant height(l) $=15 feet$

Surface area of the cone

= $\pi rl+\pi r^2$

As, $\pi =\frac{22}{7}=3.14$

Surface area of the cone = $(3.14*4*15)+(3.14 *4*4)$

$=(3.14*60)+(3.14*16)\\\\=188.4+50.24\\\\$

$=238.64feet^2$

The surface area of the cone $=238.64feet^2$
