Line r's equation is

y = - 4/3x - 4

And Line s's equation is

y = 2/5x - 2

Answer:

s = − 0.8 or a fraction - 4/5 or s = 4 if you didn't mean the s on the 8

Step-by-step explanation:

Answer:

P(X<129) ≈ 0.8849

Step-by-step explanation:

I've attached a graph of the normal distribution to help you visualize the problem. To calculate this on a TI-84, we can use the normalcdf function to find the area between the end of the left-tail of the normal distribution to x=129, hence, we are finding P(X<129). We can write this as normalcdf(-1e99,129,105,20) ≈ 0.8849, therefore, the probability that a randomly selected adult has an IQ less than 129 is about 0.8849 or about 88.49% likely to occur.

Answer: 6/4x

Step-by-step explanation:

Slope = Change in y/Change in x

5y-4 = 21

Add 4 on both sides to isolate y. (get rid of -4)

5y = 25

Divide 5 on both sides to solve for y.

y = 5

Answer:

Y is equal to 5

Step-by-step explanation:

5y - 4 = 21

5y = 21+4

5y = 25

Y = 25 ÷5

Y = 5

Answer:

James is paying $0.17 per ml.

Step-by-step explanation:

To get this answer you divide the amount purchased by the amount spent: 3.43/20

This will give you 0.1715, which rounds down to 0.17 (which is 17 cents)

[tex]\frac{3x4}{\sqrt{3} }[/tex]

[tex]\frac{\sqrt{3}\sqrt{3}\cdot \:4}{\sqrt{3}}[/tex]

[tex]=\sqrt{3}\cdot \:4[/tex]

[tex]=4\sqrt{3}[/tex]

Step-by-step explanation:

Hey there!

2^3 * 3^2

2^3

= 2 * 2 * 2

= 4 * 2

= 8

3^2

= 3 * 3

= 9

8 * 9

= 72

Therefore, your answer is: 72

Answer:

G

Step-by-step explanation:

An equation of proportionality has the form

y = kx ← k is the constant of proportionality

y = 25x ← has this form with k = 25

y = 5x ← has this form with k = 5

The required equation is y = 25x with k = 25 → G

The Greatest Common Factor of 20, 30, and 55 will be 5.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that, the numbers 20, 30, and 55.

The biggest divide between the two numbers is the greatest common factor. List each number's prime factors before calculating its greatest common factor.

20=5×2×2

30=5×2×3

55=5×11

One 2 and one 3 are the same for  20, 30, and 55. We multiply them to obtain the GCF, so the GCF of 20, 30, and 55 is 5.

Since we frequently work with fractions and they are prevalent in daily life, the greatest common factors (GCF) are very helpful. A fraction or ratio can be successfully simplified by determining the GCF of the denominator and numerator.

Thus, the Greatest Common Factor of 20, 30, and 55 will be 5.

Answer:

The answer is either 9, -9, 1, or -1

Answer:

No solution

Step-by-step explanation:

Answer:

No Solution

Step-by-step explanation:

to solve for 'x' distribute the 2 on the left side and the 5 on the right side:

17 + 16x - 10 = 10 + 25x - 9x

combine 'like terms':

7 + 16x = 10 + 16x

There is no value for 'x' that would ever make the two sides equal ∴

No Solution

Answer:

72

Step-by-step explanation:

If you take s + 19 = 8s - 100 , you will get 17, so s = 17. Plus 17 into 4s + 4 and you will get 72. DC = BE, so BE = 72.

Answer:

the answer is 29 degrees

Step-by-step explanation:

180 is the total of all the angles added together so if you subtract the 122 from 180 and divide by 2 you can get 29 for both and if you add it all together you should get 180 :)

Answer:

29

Step-by-step explanation:

pretty ez, so like a triangle got 180 degress total. what u gota do my man, is substract 122 from it.  And u get 58 and they both are equal so u divide by 2 and u get 29.
