Graph the solution of the inequality –3(x + 1) ≤ 6 on the number line.

fomenos

First you solve the inequality. Add the variables that can be added together. That would be -3 + 1=2. Now the equation is 2 + x<6. After you change the 2 into a negative and put it under the 6 and subtract. that is 3. 3 is the number you put on the number line. When you fine and plot three you make a dot above it. You fill in the dot since the less then sign has a line beneath it. Then you draw a line from the dot to the end of the number line from the direction the sign is facing. It’s a less then sign, so you would draw the line to the left.

Val buys a computer for $920. If this is 115% of what the store paid for the same computer, how much did the store earn on the s

noname [10]

Hi!

We will solve this using rations, like this:

$920 equals to 115% = 1,15

$x equals to 100% = 1

_______________________

x = (920*1)/1,15

x = 920/1,15

x = 800

Store earned 15%, or in this case 920 - 800 = $120.

Hope this helps!

Write the equation in exponential form. Log 4 1/16 =-2

steposvetlana [31]

Answer:

see explanation

Step-by-step explanation:

Using the rule of logarithms

• $log_{b}$ x = n ⇔ x = $b^{n}$

Hence

with b = 4 and n = - 2

$log_{4}$ $\frac{1}{16}$ = - 2, then

$\frac{1}{16}$ = $4^{-2}$ ← in exponential form

What is the y-intercept of the equation of the line that is perpendicular to the line y = 3/5x + 10 and passes through the point

melisa1 [442]

The slope of the perpendicular line is the negative reciprocal of that of the given line, so is
-1/(3/5) = -5/3
Then the point-slope equation of the perpendicular line can be written as
y = (-5/3)(x -15) -5
y = (-5/3)x +20

The y-intercept of the perpendicular line is y=20.
