Answer:

y = -2x - 2

Step-by-step explanation:

the equation of a linear graph is y = mx + b

you know the m = -2

so now the equation is y = -2x + b

from here, what you could do to find b is...

plug (-2, 2) into the equation

1) x = -2, y = 2

2) 2 = -2(-2) + b

3) 2 = 4 + b

4) -2 = b

or you can look at the y-intercept which is where the line intersects with the y-axis

it seems to be (0, -2)

so "b" would be equal to -2

this makes the final equation y = -2x + (-2) or y = -2x - 2

A monument has a base and a statue. The base is a rectangular prism that measures 4 ft by 6ft by 2 ft. The statue is a cube with

valina [46]

So find the volume of the separate shapes. For rectangular prisms (which includes cubes), multiply width by height by length. So multiply 4 by 6 by 2. And for the cube, multiply 2 by 2 by 2. Then, to find the total volume, add the two together.

What is the value of y in the solution to the following system of equations?

ddd [48]

2x+ y = -4 5x + 3y = -6
y= -4 -2x

substitute y=-4-2x into 5x+3y=-6
5x + 3(-4-2x) = -6
5x -12 -6x =-6
-x=6
x=-6

sub x=-6 into 2x+y=-4
-12 + y = -4
y=8

x=-6 and y=8

Show that the following argument with hypotheses on lines 1–2 and conclusion on line c is

Sonja [21]

Answer:

Step-by-step explanation:

$p \Rightarrow q \equiv (\neg p \vee q)$ [logical equivalence]

$\neg (q \vee r) \equiv (\neg q \wedge \neg r)$ [morgan laws]

if $(\neg q \wedge \neg r)$ is true, then $\neg q$ is true and $\neg r$ is too.

with $\neg q$ true, then $q$ is false [double denial]

In the first equivalence it follows that $\neg p$ is true [identity law]

Then it can be concluded that $\neg p$

kvasek [131]

Answer:

16 square meters

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.

My answer:

As we know the surface area of a square pyramid is:

SA = $a^{2}$ + (2 × a × s), where a is the base length and s is the slant height.
