Y = 9x + 14 y = 4x + 49

ipn [44]

Answer:

x = 7; y = 77

Step-by-step explanation:

y = 9x + 14

y = 4x + 49

Since both equations are solved for y, set the two right sides equal and solve for x.

9x + 14 = 4x + 49

5x = 35

x = 7

Sow substitute 7 for x in the first equation and solve for y.

y = 9x + 14

y = 9(7) + 14

y = 63 + 14

y = 77

Answer: x = 7; y = 77

X2 + 8x + 19 = 0 What is the equivilent that results from completing the square?

IrinaVladis [17]

Answer:

$(x+4)^2+3=0$

Step-by-step explanation:

Hey there!

Standard form is what this equation is in

Standard form is this: $ax^2+bx+c$

So order to complete the square, you need to take the $b$ term out of the equation, divide it by two, and then square it

In this case, the $b$ term is 8

We need to divide 8 by 2 ---> 4

Then square 4 ---> 16

So now you should add 16 to both sides

$x^2+8x+16+19=16$

Now you can simplify the LHS

$(x+4)^2 +19=16$

Now you subtract 16 from both sides

$(x+4)^2+3=0$

So this is as far as you can go since you cannot take the square root of a negative number

Geometry Surface area and volume

Zigmanuir [339]

Answer:

$volume=558.9$

Step-by-step explanation:

find the volume of the cone and the hemisphere and add them together

cone:

$Vcone=\pi r^{2} \frac{h}{3} \\\\V=\pi (5.3)^2(\frac{8.4}{3} )\\V=\pi (28.09)(2.8)\\V=247.09\pi \\V=247.1$

hemisphere:

$Vhemisphere=\frac{2\pi r^3}{3} \\V=\frac{2\pi (5.3)^3}{3} \\V=\frac{2\pi (148.877)}{3} \\V=\frac{297.754\pi }{3} \\V=\frac{935.421}{3}\\ V=311.8$

add the volumes together:

$Vol=247.1+311.8\\Vol=558.9$
