4x + 3 < -1
Cual es la respuesta

Answers

Answer 1

Answer:

For this case we have the following inequality:

$4x + 3 <-1$

To solve we follow the steps below:

We subtract 3 from both sides of the inequality:

$4x <-1-3$

Equal signs are added and the same sign is placed.

$4x <-4$

We divide between 4 on both sides of the inequality:

$x <\frac {-4} {4}\nx <-1$

Thus, the solution is given by all values of "x" less than -1.

Answer:

$x <-1$

What is 575 percent written as a mixed number

Answers

a mixed fraction is an improper fraction turned into a whole number and a proper fraction
proper fraction: top number is SMALLER than the bottom number (fraction means part of) exg 1/3

improper fraction: top number is GREATER than the bottom number (more than 1) exg. 4/3

mixed: an improper fraction written as a whole number and a proper fraction exg
4/3=imporper mixed=1 and 1/3

so
575%
percent means parts out of 100
575%=575/100=57.5/10=5.75/1=5.75/1=5.75=5 and .75/1
we know that 0.75=3/4

so
5 and 3/4 is the answer

575%= $(575)/(100)^(/25) = (23)/(4) =5 (3)/(4)$

(-2,-4) (2,4) what is the answer in slope intercept form

Answers

Answer:

y = 2x

Step-by-step explanation:

We can find the slope

m = (y2-y1)/ (x2-x1)

= (4--4)/(2--2)

= (4+4)/(2+2)

= (8/4)

= 2

We can use the point slope form of the equation

y-y1 = m(x-x1)

y--4 = 2(x--2)

y+4 = 2(x+2)

Distribute the 2

y+4 = 2x+4

Subtract 4 from each side

y+4-4 = 2x+4-4

y = 2x

y+2 = 2x+4

Find the multiples of 8 and 12, the lowest one they have in common will help with your answer.

8 : 8 16 24 32 40 48 56

12 : 12 24 36 48

The number that they both have (least) in common is 24.

For 8, it is the 3rd multiple and for 12 it would be the second

Two integers, a and b have product of -48 what is the greatest possible sum of a and b.

Answers

The factors of 48 are:
1 x 48
2 x 24
3 x 16
4 x 12
6 x 8
and visa versa: 48 x 1 etc.

To make the product negative, one of the factors has to be positive and one has to be negative. To find the greatest sum, make the bigger number the positive factor and the smaller number the negative factor. So, -1 x 48 = -48 and the sum of -1 + 48 = 47 which would be the greatest possible sum.

2. The cost of a pen at the office supply store is $2.65. The school store sellsthe pen for $3.45. How much does the school store markup the pen?

Answers

Answer:

THE SCHOOL RAISES THE PRICE BY 30%

Step-by-step explanation:

I SUBTRACTED 3.45 FROM 2.65 THEN I DEVIDED THE DIFFERENCE BY 2.65 THEN MULTIPLIED BY 100 TO GET IT IN PERCENT.

PLEASE GIVE ME BRAINLIEST.

WELCOME

Final answer:

The school store marks up the pen by $0.80.

Explanation:

To find the markup on the pen, we need to subtract the cost price of the pen from its selling price. The markup is the difference between the two prices. In this case, the cost price of the pen is $2.65 and the selling price is $3.45. To calculate the markup, we subtract $2.65 from $3.45:

Markup = Selling Price - Cost Price

Markup = $3.45 - $2.65 = $0.80

So, the school store marks up the pen by $0.80.
