15x+7y=5 find the y-intercept

Answer:

1. 6+7= 13

2. 6-7= -1

3. 6+7= 13. (- × - = +)

4. -6-7= -13

5. -6-7= -13. (+ × - = -)

_________

[tex] \: [/tex]

1.) 6 + 7 = (5 × 2) + (1 + 2) = 10 + 3 = 13✔

2.) 6 - 7 = (5 - 5) + (1 - 2) = 0 + (-1) = -1✔

3.) 6 - (-7) = 6 + 7 = (5 × 2) + (1 + 2) = 10 + 3 = 13✔

4.) -6 - 7 = (-6) + (-7) = -(6 + 7) = -13✔

5.) -6 + (-7) = -(6 + 7) = -13✔

Answer:

∠4 = 110

Step-by-step explanation:

∠3 + ∠5 = 180    {Co-interior angles are supplementary}

2y + 20 + 210 - 4y = 180

2y - 4y + 20 + 210 = 180    {Combine like terms}

-2y + 230 = 180

Subtract 230 from both sides

-2y = 180 - 230

-2y = -50  

Divide both sides by (-2)

  y = -50/-2

y = 25

∠5 = 210 - 4y

      = 210 - 4*25

       = 210 - 100

∠5 = 110

∠4 = ∠5    {Alternate interior angles are equal}

∠ 4 = 110°

Answer: The Inverse Function goes the other way: So the inverse of: 2x+3 is: (y-3)/2. The inverse is usually shown by putting a little "-1" after the function name, like this: f -1(y) We say "f inverse of y". So, the inverse of f(x) = 2x+3 is written: f -1(y) = (y-3)/2.

$464.24095

Step-by-step explanation:

8 1/4% = NY sales-tax rate

8 1/4 % = .0825

428.86 x .0825 = 35.38095

428.86 + 35.38095 = $464.24095

Step-by-step explanation:

Your line has a 1 to 1 ratio of rise over run.

Answer:

(12 + x)/(15 + x) = 85/100

Step-by-step explanation:

12/15 = 0.8

She currently has an 80% rate.

To raise it, she needs to make x shots. Since she makes all x shots, we add x to both the number of shots made and attempts.

She will make 12 + x shots in 15 + x attempts.

We want that rate to be 0.85 which is the same as 85%.

(12 + x)/(15 + x) = 85/100

(12 + x)/(15 + x) = 17/20

20(12 + x) = 17(15 + x)

240 + 20x = 255 + 17x

3x = 15

x = 5

Answer:

The equation is (12 + x)/(15 + x) = 85/100.

The salary differences are found to be statistically significant.

Statistical significance refers to the claim that a result from data generated by testing or experimentation is not likely to occur randomly or by chance but is instead likely to be attributable to a specific cause.

It is given that

Average 6 foot plus male’s salary = $55,000

Average male’s salary under 6 foot tall = $47,000

p-value = 0.45

As the p-value 0.45 is greater than p-value 0.05,

So statement men over 6 feet tall earn more than men under 6 feet is acceptable, we can say that salary differences are statistically significant.

Therefore, The salary differences are found to be statistically significant.

Answer:

Step-by-step explanation:

1.

3,4,5 will make a triangle.

2.

sum of any sides > third side

difference of any two sides < third side

3+4=7>5

4+5=9>3

5+3=8>4

again

4-3=1<5

5-3=2<4

5-4=1<3

so it makes one triangle.

3.

3,4,8

4.

3+4=7 not >7

again

8-4 =4 not <3

so they do not make a triangle.

The value of given numerical expression is 128.

The given numerical expression is [8²×(2+6)]/4.

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.

Now, the given expression can be solved as follows:

[8²×(2+6)]/4

= (64×8)/4

= 64×2

= 128

Therefore, the value of given numerical expression is 128.

Answer:

x = 2

Step-by-step explanation:

5(x-4) =-10

Distribute 5 by multiplying x and -4 by 5

5x - 20 = -10

Add 20 to both sides

5x - 20 + 20 = -10 + 20

5x = 10

Divide both sides by 5

5x ÷ 5 = 10 ÷ 5

x = 2
