1.8 minus 3.7 x = negative 4.2 x + 0.3?

Combine like terms. First, add 4.2x to both sides. This results in 1.8+0.5x = 0.3, and then 0.5x = 0.3-1.8.

Next, 0.05x = -1.5, or 5x = -150, and x = -30.

Must check this result by substitution of -30 for x in the original equation.

Is 1.8-3.7(-30)=-4.2(-30)+0.3 true or false?

Answer:

56

Step-by-step explanation:

Hey There!

so this is a parallelogram so opposite angles are congruent

So basically what i am saying is that angle P is congruent to angle R

So we need to solve for x

We know that angle P and angle Q are supplements meaning that they will add up to 180

so we setup the equation

180=3x+5+8x-12\\

step 1 combine like terms

3x+8x=11x\\5-12=-7

now we have

180=11x-7

step 2 add 7 to each side

180+7=187

-7+7 cancels out

now we have

187=11x

step 2 divide each side by 11

187/11=17

x=17

now we plug in 17 to (3x+5) to get the value of angle R

17x3=51

51+5=56

therefore m∠R = 56

What is the domain of the function y=in(x+2) x<-2 x>-2 x<2 x> x<-2 x>-2 x<2 x>2
aev [14]

For this case we must find the domain of the following function:

y = ln (x + 2)

By definition, the domain of a function is given by all the values for which the function is defined.

In this case, the argument of the expression must be greater than 0 to be defined.

x + 2> 0\\x> -2

Thus, the domain of the function is given by all the values of x greater than -2.

Answer:

Domain: x> -2
