Step-by-step explanation:

first substitute x. then multiply by 2 . the answer is 17.

Answer:

3 - 2x = 17

Step-by-step explanation:

Given information,

→ 3 - 2x

→ x = -7

Let's solve the problem,

→ 3 - 2x

→ 3 - (2 × -7)

→ 3 -(-14)

→ 3 + 14 = 17

Hence, the answer is 17.

Pet supplies makes a profit of $5.50 per bag on it’s line of natural dog food. If the store wants to make a profit of NO LESS THAN $5225, how many bags of dog food does it need to sell???

10 pts for a clear explanation

Answers

950 bags of dog food,
because 5225 divided by 5.50 is 950
I think this is correct

Answer:

the pet store needs to sell 950 or more bags of dog food.

Step-by-step explanation:
Let’s define our variable: x= number of bags of dog food.
Since we need to make more than or 5225 dollars, we need to make an inequality to show this.
[tex]5.50x\geq 5225[/tex]

Let’s solve the inequality.

[tex]5.50x/5.50 \geq 5225/5.50[/tex]

[tex]x\geq 950[/tex]

So, the pet store needs to sell 950 or more bags of dog food.

Samantha is buying a chromebook that costs $179.00. The chromebook is on sale for 35% off the original price. How much will the chromebook cost after the discount?

Answers

Answer:

$116.35

Step-by-step explanation:

179 x 35/100

= 62.65

This is how much will be taken off of the original price. So we have to subtract that from 179.

179 - 62.65 = 116.35

The new price is $116.35

Answer:

$116.25 after the discount

Step-by-step explanation:

$179 - 35% = x

$179 - $62.25 = $116.75

Sarah Jane bought a pair of joggers that were on sale for 40% off the original price. If the original price was $39.00, what was the sales price of the joggers?

Answers

The sales price of the joggers is $23.99

________________________________

Discount = Original Price x Discount %/100

Discount = 39.99 × 40/100

Discount = 39.99 x 0.4

________________________________

Final Price = Original Price - Discount

Final Price = 39.99 - 15.996

Final Price = $23.99

$39.00x40%

$15.60

$39.00-$15.60

Answer: $23.40

(PLEASE HELP) What is the slope of the line that contains the points (2, −7) and (−1, 5)?

A: −4
B: negative one fourth
C: one fourth
D: 4

Answers

The answer is -4

You do 5 - -7=12 and then do -1 -2 which is -3 and then you do 12/-3=-4

Equation m = -4 gives the slope of the line.

What exactly is a line equation?

A line's equation is written as y = mx + b, where m denotes the slope and b the y-intercept.

And m (x - x1) = y - y1

y = the second point's y-coordinate

y1 = the y-coordinate for point one, m = the slope, and x = the x-coordinate for point two.

x1 = the point one's x coordinate

The m = y/x slope

Given the data,

Right now, A is valued at

Let P be the initial point ( 2 , -7 )

Let Q be the second point ( -1 , 5 )

The slope of the line is now given by m = (y2 - y1) / (x2 - x1).

Slope m is equal to (-7 - 5) / (2 - (-1)

The equation is simplified to give Slope m = -12 / 3.

Slope m = -4

Hence, m has a value of -4.

As a result, the line's slope is m = -4.

Answer: -5/4

Step-by-step explanation:

It is this because it is a downward slope, and so it has to be negative. The points are 10 at the top and eight at the bottom. But Because the slope goes down to the right, it means that it is going to be negative. So, -10/8 can be simplified down to -5/4 when divided by 2. Hope this helps.

The answer is -5/4 It is this because it is a downward slope, and so it has to be negative.

A full grain silo empties at a constant rate. write an expression to determine the amount of grain left after s seconds
Rate ; 3.5ft 3/s
Capacity ; 3000ft3

Answers

slope intercept form of a straight line equation is y = m * x + b.

m is the slope.
b is the y-intercept.

the slope is the same as he constant rate.

let y = the number of feet of grain left in the silo.

let x = the number of seconds.

you get y = -3.5 * x + b.

when x = s seconds, the equation becomes y = -3.5 * s + b.

b is the y-intercept which is the value of y when x = 0.

when x = 0, no seconds have elapsed and the silo is therefore at whatever height it was before you started to empty it.

that would be the value of b.

if we assume that the height of the grain in the silo was 150 feet, then the formula would become: y = -3.5 * x + 150

after s seconds, the formula would become y = -3.5 * s + 150.

if s was equal to 20, then the formula would become y = -3.5 * 20 + 150 which would then become y = -70 + 150 which would then become y = 80.

after 20 seconds, there would be 80 feet of grain left in the silo.

80 feet of grain silo ..

Answers

Answer:

They are not similar.

Step-by-step explanation:

In triangle ABC, the angle we are given is in between the two defined sides(AB and BC with angle B). If these triangles were similar, we would see this with the SAS postulate.

In triangle KLJ, the angle is not in between the two sides, so they are not similar according to any of these two postulates.
