What is the slope of the line shown below?
(-2,5)
(3.-5)

Answers

Answer 1

Answer:

-5/10 or -1/2

Step-by-step explanation:

to find slope from two points, subtract the first y from the second (-2 - 3 = -5) and then subtract the first x from the second (5 - -5 = 10) and the answer is -5/10 which is equivalent to -1/2

the actual formula is [tex]\frac{y1-y2}{x1-x2}[/tex]

Answers

Answer:

Points ( 0, 13) , ( 30, 18) , ( 90 ,28)

Rate = y2-y1/x2-x1

Rate = 28-13 / 90-0 = 1/6 inches / Mins

Answers

Answer:

Second choice.

Step-by-step explanation:

Option 1: solve the inequality. Add 7 to both sides, and multiply by -3 (don't forget that this makes the inequality switch direction!) to get [tex]x > {27 \over {-3}[/tex] or x > -9

Option 2. Plug 0 in it. You get -7 < 20, which is obviously true. So 0 is in the set of solution and it means B and C are possible solutions. So let's check another easy value. let's say -10. replacing it you get [tex]-3 (-10) -7 < 20[/tex] or [tex]30 -7 <20[/tex]. But 23 is obviously greater than 20, which means -10 is not a part of the solution. Correct answer is B

Answer:

64 ounce bottle of orange juice  has a greater percent of water

Step-by-step explanation:

Case 1) An 80 ounce bottle of apple juice contains 32 ounces of water

Total quantity of bottle = 80 ounces

Amount of water = 32 ounces

So, Percent of water = [tex]\frac{32}{80}[/tex] x 100

                                 = 40%

Case 2) An 64 ounce bottle of orange juice has 48 ounces of water

Total quantity of bottle = 64 ounces

Amount of water = 48 ounces

So, Percent of water = [tex]\frac{48}{64}[/tex] x 100

                                 = 75%

Hence 64 ounce bottle of orange juice  has a greater percent of water

Sam invests a sum of money into an account that pays 3%

Answers

Answer: It would take 24 years to double your investment.

Hope this helps!

Sam will have doubled his investment for 33 years.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that Sam invests a sum of money into an account that pays 3%

compound interest per annum

We need to find how many years Sam will have doubled his investment.

With C your initial capital, k the interest rate and t the number of years. Since k is given as a simple interest rate, you’re essentially trying to solve :

C(1+tk)=2C

With a little bit of algebra, you should find that:

t=1/k

k=3%=0.03

t=1/0.03=33.33=33 years.

Hence,  Sam will have doubled his investment for 33 years.

Answer:

x= 7

B= 112

F= 68

Step-by-step explanation:

to find x we set up an equation, (16x)=(4x+84). They are alternate interior angles which are always equal.

calculate it and you'll find x=7.

B and the angle 4x+84 are equal because they are vertical angles, to find it we just put 7 instead of x into 4x+84.

4(7)+84=112

angle f is supplementary to 16x. 16x is also 112 because they are equal, so its just 180-112=68

Using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

hope this helps you.

✌️✌️✌️

The sum of the measure of angle ∠AXY and angle ∠YXB is the measure of ∠AXB.

The relationship between ∠AXY and ∠YXB is that they are;

Complementary angles

Reasons:

From the diagram in the question, we have;

∠BXC = 90° Given

∠BXC and ∠BXA are linear pair angles

Therefore;

∠BXC and ∠BXA are supplementary angles, which gives;

∠BXC + ∠BXA = 180° definition of supplementary angles

Therefore;

∠BXA = 180° - ∠BXC

∠BXA = 180° - 90° = 90°

∠BXA = 90°

∠AXY + ∠YXB = ∠BXA by angle addition property

Which gives;

∠AXY + ∠YXB = 90° by substitution property

Therefore ∠AXY and ∠YXB are;

Complementary angles,  by definition of complementary angles.
