Answer:

x = 4y + 28

Step-by-step explanation:

x/4 - 7 = y

+7              +7

x/4 = y + 7

× 4             × 4

x = 4y + 28

Answer:

x = 4y + 28

Step-by-step explanation:

For this, you would need to simplify both sides of the equation, after isolating the variable.

irga5000 [103]
<h2><u>Solution</u>:</h2>

<em>To find the zero,</em>

<em>x</em> + 1 - 4 = 0

<em>x</em> = 4 - 1

<em>x</em> = 3

3 is the <u>root</u> of <em>(x + 1) - 4</em>.

Caitlyn did 6/7 of the problems on her math correctly and 4 incorrectly. She did all the problems. How many were there?
Viefleur [7K]
If \frac{6}{7} were incorrect, it means that \frac{1}{7}=4 were correct
4*7=28
There were 28 problems ;)

What is the value of y?
VikaD [51]

The answer is 57 because using remote angles theorem you get the largest angle equals to 66 degrees but you are not done yet you have to subtract 66 from 180 because of sum of angles in a triangle so you get 114 degrees and since you have an isosceles triangle you have to divide by two to get y so y = 57 degrees

Use vieta's theorem to solve the problems.
Mnenie [13.5K]

Using Vieta's Theorem, it is found that c = 72.

<h3>What is the Vieta Theorem?</h3>
  • Suppose we have a quadratic equation, in the following format:

y = ax^2 + bx + c

  • The roots are p and q.

The Theorem states that:

p + q = -\frac{b}{a}

pq = \frac{c}{a}

In this problem, the polynomial is:

x^2 - 17x + c

Hence the coefficients are a = 1, b = -17.

Since the difference of the solutions is 1, we have that:

p - q = 1

p = 1 + q

Then, from the first equation of the Theorem:

p + q = -\frac{b}{a}

1 + q + q = 17

2q = 16

q = 8

p = 1 + q = 9

Now, from the second equation:

pq = \frac{c}{a}

72 = c

c = 72
