Answer: x < 4.6 rounded to the tenths

Step-by-step explanation:

3.8x + 14.5 < 32

subtract 14.5 on both sides.

3.8x < 17.5

divide by 3.8 on both sides.

x < 4.60526316

Handy Dandy Grocery is having a sale this week. If you buy a 5−pound bag of apples for the regular price, you can get another ba
Elis [28]

Answer:

To get the discount for the 5 pound bag of apples, we must first note the following:

The original price of the apples, which in this case it is 2.99

Also we must note the sale price for the apples which is 1.59

to get the discount for apples we must then create an equation based on the above information,

Discount for A= original price -sale price

Discount for A=2.99-1.59

Discount for A=1.40

Part 1 Answer is 1.40 which is the discount for apples at Handy Dandy Grocery.

Part 2

To get the discount for oranges we follow the same steps.

Discount for R= Original price for R -sale price for R

Discount for R=3.99-2.59

Discount for R=1.40

conclusion, for both part one and part two we can derive a formula based on the apples and orange and say discount in both cases is arrived by the following:

D=Op-Sp. ( d= discount, Or= original price, Sp= sale price.)

An equation in slope-intercept form of the line

p=-\frac{9}{2}w+268\\

Given :

Bill began his diet when he weighed 268 pounds.

After 4 weeks he weighed 250 pounds

Lets 'w' represents weeks and 'p' represents pounds

Using the given information ,we find two points (w,p)

Bill began his diet when he weighed 268 pounds.

when w=0 , weight in pounds =268

(0,268)

After 4 weeks he weighed 250 pounds, so point is (4,250)

Use two points to write the equation of line

Slope intercept form is y=mx+b

where m is the slope and b is the y intercept

slope formula using 2 points (0,268) and (4,250)

m=\frac{y_2-y_1}{x_2-x_1} =\frac{250-268}{4-0} =-\frac{9}{2}

now use slope m and any one point (0,268) to write equation

y=mx+b\\y=-\frac{9}{2}x+b\\(0,268) where x=0  and y=268\\268=-\frac{9}{2}(0)+b\\\\b=268

we know that w represents weeks and p represents pounds

The equation of the line in slope intercept form is

p=-\frac{9}{2}w+268\\

What is the value of p such that the line passing through (6,2) and (9,p) has a slope of -1?
Aleks [24]

Answer:

p= -1

Step-by-step explanation:

gradient=<u>y</u><u>²</u><u>-</u><u>y</u><u>¹</u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>x²-x¹

-1 =<u>p</u><u>-</u><u>2</u>

<u> </u><u> </u><u> </u><u> </u><u> </u>9-6

-1=<u>p</u><u>-</u><u>2</u>

<u> </u><u> </u><u> </u><u> </u><u> </u> 3

multiply both sides by 3 to remove the denominators

-1×3=p-2

-3=p-2

put the like terms together

-3+2=p

-1=p
