Answer:

Make all of the +/-2 values into -3,+4

Step-by-step explanation:

This is because the x intercept values for a parabola are where the equation equals zero, by making the equations -3 and +4, the equations will give zero values at -4 and plus 3 when they are set equal to zero, I can specify further if need be.

Answer:

  15

Step-by-step explanation:

Let 'a' represent Artaud's age. He notices the relationship ...

  -a +39 = 24

If we add a-24 to both sides, we get ...

  15 = a

Artaud is 15 years old.

Answer: 15 years old

Step-by-step explanation:

Let x be Artaud's age. Let the opposite of his age be -x

-x + 39 = 24

-x = 24-39

-x = -15 (multiply both sides by -1)

x = 15 years old

Answer:

∠ECD = 82°

Step-by-step explanation:

Alternate Interior Angles Theorem : when two parallel lines are cut by a transversal, the alternate interior angles are congruent.  Alternate angles form a Z shape and are sometimes called "Z angles".

Therefore,

∠CDF = ∠GBC = 45°

∠CEF = ∠GAC = 53°

The sum of the interior angles of a triangle is 180°

⇒ ∠ECD + ∠CDF + ∠CEF = 180

⇒ ∠ECD + 45 + 53 = 180

⇒ ∠ECD = 180 - 45 - 53 = 82°

In ∆ABC

[tex]\\ \tt\longrightarrow x+53+45=180[/tex]

[tex]\\ \tt\longrightarrow x+98=180[/tex]

[tex]\\ \tt\longrightarrow x=180-98[/tex]

[tex]\\ \tt\longrightarrow x=82[/tex]

Now

m<ECD and m<ACB are opposite hence equal

[tex]\cfrac{5}{8}\cdot \cfrac{8}{25}\implies \cfrac{5}{25}\cdot \cfrac{8}{8}\implies \cfrac{1}{5}\cdot 1\implies \cfrac{1}{5}[/tex]

Answer:

slope = 9/4

Step-by-step explanation:

Slope is a ratio (looks like a fraction) It tells you the steepness or flatness of a line.

To find slope you subtract the y's (that's the second number in the ordered pairs; here it's 10 and 1) put that on top. Then subtract the x's and put that on the bottom (here 9 and 5)

Slope = 10-1 / 9-5

=9/4

Now, parallel lines have the same slope, so if one of the lines has slope 9/4, then the other line does too!

By using the equivalence of the formed angles, the solution is x = 41.

Note that the angle that is at the right of the equation with x, is equivalent to the bottom right angle, which measures 60°.

Then we will have that:

(3x - 3)° + 60° = 180°

Now we can solve that for x:

(3x - 3)° = 180° - 60° = 120°

3x = 120 + 3

x = 123/3 = 41

The solution is x = 41

DIVIDE 12 to BOTH SIDES

12x/12 = 180/12

It is meaningful to compute the probability that a continuous random variable when it is between two numbers.

Probability is a ratio of the number of favorable outcomes to the number of possible outcomes of the experiment.

Continuous random variable is is one which takes an infinite number of possible values.  A random variable is said to be continuous if it assumes a value that falls between a particular interval.

So, from the above mentioned statement we can assume that ;

The statement given in option [tex](c)[/tex] is correct .

Answer:

  24.5 mi

Step-by-step explanation:

  (2.5)(9.8 mi) = 24.5 mi

From Old Faithful to West Thumb is 24.5 miles.

Answer:

24°

Step-by-step explanation:

Let x = one complementary angle

Let y = the other complementary angle

As the sum of two complementary angles is 90°:

x + y = 90

If one angle is 18° more than two times the other angle:

y = 18 + 2x

Rewrite x + y = 90 to make x the subject:

x = 90 - y

Now substitute x = 90 - y into y = 18 + 2x and solve for y:

y = 18 + 2(90 - y)

⇒ y = 18 + 180 - 2y

⇒ 3y = 198

⇒ y = 198 ÷ 3 = 66

Now substitute found value of y = 66 into x + y = 90 and solve for x:

x + 66 = 90

⇒ x = 90 - 66 = 24

Therefore, the larger angle = 66° and the smaller angle = 24°

Answer:

9 numbers

Step-by-step explanation:

10^2 + 10 = 110. This is also greater than 100.

Highest value of x is 9.

9^2 + 9 = 90.

Not sure if zero counts, but if it does, it'll be 10 numbers instead.

Hope this helps!

There are 9 positive integers x satisfy the inequality x² + x < 100.

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

We have the inequality

x² + x < 100.

First take x= 1 then

1² + 1 = 2 < 100

Take x= 2

2² + 2 = 6 <100

Take x= 3

3² + 3 = 12 < 100

Take x = 4

4² + 4 = 20 < 100

Take x= 5

5² + 5 = 30 < 100

Take x =6, 7, 8, 9, 10 and 11

6² + 6<100

7² + 7<100

8² + 8<100

9² + 9 <100

10² + 10 > 100

So, there are 9 possible digits.

Answer:

45% increase

Step-by-step explanation:

The new number (87) is bigger than the original number (60), so this is a percent increase.

To find the percent of change, which in this case is a percent increase, take the change amount and divide by the original, then convert to a percent.

Subtract to find the change.

87 - 60 is 27.

27 is the amount of change.

change/original

= 27/60

= .45

Times by 100 to change to a percent.

.45 × 100

= 45%
