Graph the piecewise function

f(x)= {-2x-3 if -1

Answer:

y=2x-1

Step-by-step explanation:

Isolate the variable y to solve it. You end up with y=2x-1

The lights which were on was 48%.

A percentage is a number or ratio that can be expressed as a fraction of 100.

Given that there were 72 lights on, and 78 lights turned off.

We need to find the percent of the lights turned on.

So, percentage of something =

= number of thing / total number of the thing x 100%

Here, the number of thing = light on = 72

Total = 72 + 78 = 150

So, the percent of light on = 72 / 150 x 100% = 0.48 x 100%

= 48%

Hence the lights which were on was 48%.

It is 350 because 10 ones is 10, 4 tens is 40, and 3 hundreds is 300 if you add them up you get 350.

The required number is 350 which represents 10 ones, 4 tens

and 3 hundred.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We have been given information as

10 ones

4 tens

3 hundred

As per the given question,

Translate the information into an algebraic expression:

It's 350 since 10 ones are 10, 4 tens are 40, and 3 hundred is 300 when added together.

⇒ 1 × 10 + 4 × 10 + 3 × 100

⇒ 10 + 40 + 300

⇒ 350

Therefore, the required number is 350 which represents 10 ones, 4 tens

and 3 hundred.

Your answer What is the value of x, you didn't specify

Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.

Answer:

y= 6

Step-by-step explanation:

First you substitute in the 8 for x. you then multiply 8 times 8 which equals 64. you subtract 64 from 4 and 64, since it would be the opposite of addition. you would then take the -10y=-60, and you would divide by negative 10 to get y by itself. since negative 60 divided by negative 10 is a positive 6, your answer would be y equals 6.

Step-by-step explanation:

angle < EDG = 90°

5x + 4x = 90

9x = 90

x = 90/9

x = 10°

which means

5x = 50°

4x = 40°

---------------------------

sice EF and DG are parallel lines

EHD = 40°

DHG is 90°

then HGD = 50°

-----------------------------------------

ED = 64 x2 (2 sides) = 128 inches

DG = 84 x2 (2 sides) = 168 inches

total perimeter = 128 + 168 = 296 inches

Answer:

{n:n≤15.5}

Step-by-step explanation:

√First derive the inequality from interpreting the statement,thus 12n+4≤190

√Second, solve the derived inequality ( ie.make n the subject)

√Finally, you'll arrive at the answer as n≤15.5

Therefore the possible values of the variable n is all numbers less than or equal to 15.5

PROOF

For n greater than 15.5

Let's take n to be 20

Therefore from the derived inequality

12n+4≤190

12(20)+4 = 240

Here,240 is greater than 190

Since for n≥15.5 will not satisfy the inequality n≠all numbers more than 15.5

Answer:

He added 3.5 and 5 instead of multiplying them.

Step-by-step explanation:

P = -2x^2 + 8x + 2

for maximum P, dP/dx = 0

dP/dx = -4x + 8 = 0

4x = 8

x = 2

The company should produce 2,000 units per week to earn maximum profit.

Maximum profit = -2(2)^2 + 8(2) + 2 = -8 + 16 + 2 = 10

Explanation:

It is often useful to put everything in terms of sine and cosine.

  sin(x)·(tan(x) +cot(x))

  = sin(x)·(sin(x)/cos(x) + cos(x)/sin(x))

  = sin(x)²/cos(x) +cos(x) . . . . . . use the distributive property*

  = (sin(x)² +cos(x)²)/cos(x) . . . . . combine terms over a common denominator

  = 1/cos(x)

  = sec(x)

_____

* The expression inside parentheses could have been combined to ...

  (sin(x)² +cos(x)²)/(sin(x)·cos(x))

Then the sin/sin factors cancel, leaving the expression on line 4.

Answer:

the smaller number is 27.

Step-by-step explanation:

set two numbers are a and b

one number is less that twice of a number:

let's say a is 5 less than twice of b

so we have : a=2b-5

sum of the two numbers is 76: we have a+b=76

then we set up the system of equation[tex]\left \{ {{a=2b-5} \atop {a+b=76}} \right.[/tex]

substitude a = 2b - 5 into the second equation

we have,

2b - 5 + b = 76

3b - 5 = 76

3b = 81

b = 27

Since a + b = 76 so a = 49
