8x + 16y ≤ 4: does (2,9) work?

8(2) + 16(9) ≤ 4

16 + 144 ≤ 4

160 ≤ 4

160 is not smaller or equal to 4, so the point (2,9) does not satisfy the inequality.

At one store, a 2-liter bottle of soda costs $2.12. At another store, a 3-liter bottle costs $3.15. Which bottle is a better deal? Write a division equation for each 2-liter bottle, and then decide which is the better deal.

Answers

Answer:

The 3 liter bottle has a better deal

Step-by-step explanation:

Which bottle is a better deal?

For the 2 liter bottle

At one store, a 2-liter bottle of soda costs $2.12.

2 liter bottle = $2.12

1 liter bottle = x

Cross Multiply

2x = $2.12

x = $2.12/2

x = $1.06

Hence, this is $1.06 per liter

For the 3 liter bottle

At another store, a 3-liter bottle costs $3.15.

3 liter bottle = $3.15

1 liter bottle = x

Cross Multiply

3x = $3.15

x = $3.15/3

x = $1.05

Hence, this is $1.05 per liter

Therefore, the bottle which is a better deal is the 3 liter bottle because, 1 liter goes for $1.05

Construct the bisector of the following figures

Answers

Answer:

In these lessons, we will learn

how to construct an angle bisector of a given angle.

how to use an angle bisector to construct some angles for example, 90 degrees, 45 degrees, 60 degrees, 30 degrees, 120 degrees, 135 degrees, 15 degrees.

An angle bisector is a straight line that divides the angle into two equal parts.

Example: Construct an angle bisector for the following angle:

Solution:

Step 1 : Put the sharp end of your compasses at point B and make one arc on the line BC (point S) and another arc on line AB (point T).

Step 2 : Put the sharp end of the compasses at S and make an arc within the lines AB and BC. Do the same at T and make sure that the second arc intersects the first arc.

construct angle bisector

Step 3 : Draw a line from point B to the points of intersection of the 2 arcs. This line bisects ∠ABC.

construct angle bisector

The steps to construct an angle bisector can be summarized as follows:

1. From the vertex, draw an arc across both rays of the angle.

2. From each arc intersection draw another pair of arcs that intersect each other.

3. Draw a line from the vertex to the intersection point to form the angle bisector.

Given f(x) = x ^ 2 - (3x + 8) Find f(1)

Answers

Answer:this problem requires one to plug in the value given to the equation given. to find f(-1) the x in one side of the equation is replaced by a -1 therefore the x in the other side of the equation must also be replaced by (-1) so the answer is -3(-1) -8 = f(-1) = -5. -5 is the correct answer.

A-line includes the points (8,9) and (9,1). What is its equation in point-slope form?

Answers

Answer:

[tex]y-(9)=(-8)(x-8)\\[/tex]

Step-by-step explanation:

[tex](x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\[/tex]

Step one: Find the slope (m)

[tex]slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8[/tex]

Step two: Plug your known values into the point-slope equation

[tex]m=-8\\y_1=9\\x_1=8\\[/tex]

Point-slope form is [tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(9)=(-8)(x-8)\\[/tex]

If you want to convert point-slope form to general form, isolate for y.

[tex]y-9=-8x+64\\y=-8x+73[/tex]

440h is the expression. When 3 1/4 is evaluated you get 1,430 calories burned.

Step-by-step explanation:

440 represents the number of calories she burns per hour. To represent the hour, we place a variable which is h. After we write the expression, we substitute 3 1/4 for h. When I did this, I turned 3 1/4 into an improper fraction, which was 13/4, and then divided 13 by 4 to get 3.25

Multiple 3.25 by 440 to get an answer of 1,430 calories burned.

If the legs of a right triangle are x, (2x - 1) and its hypotenuse is (2x + 1), what is the value of x?​

Answers

Answer:

x=8

Step-by-step explanation:

(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)

(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1

4x²+2x+2x+1 = 5x²-4x+1

4x²+4x+1 = 5x²-4x+1

0= 5x²-4x²-4x-4x+1-1

0= x²-8x

x²-8x=0

x²=8x

19 3/7 - 12 6/7

Plz show how u got your answer

Answers

Answer:

16 4/7

Step-by-step explanation:

First, you cant subtract 3/7 from 6/7 so take 1 from 19, which turns it to 18. And add that one to 3/7 to get 10/7, or just add 7 to your numerator. So now you have 18 10/7 - 12 6/7. so subtract 18 - 12 to get 6, and the subtract 10/7 - 6/7 to get 4/7. You dont actually have to subtract the denominator just the numerators, because the denominatos are the same so you leave them just the way they are. I hope this helps :)

The ratio of lemons to lime in a punch is 6:4. If there are 35 fruit in the punch, how many of them are lemons?

Answers

Answer:

21 lemons

Step-by-step explanation:

If the ratio is 6:4, the ratio is also equal to 3:2. This means, for every 3 lemons, there are two limes.

So, if there are 35 lemons and limes in total, we would have 21 lemons and 14 limes.
