1.) Find the value of the discriminant and the the number of real solutions of

ruslelena [56]

Hi there!

When we have an equation standard form...
$a {x}^{2} + bx + c = 0$
...the formula of the discriminant is
D = b^2 - 4ac

When
D > 0 we have two real solutions
D = 0 we have one real solutions
D < 0 we don't have real solutions

1.) Find the value of the discriminant and the the number of real solutions of
x^2-8x+7=0

Plug in the values from the equation into the formula of the discriminant

$( - 8) {}^{2} - 4 \times 1 \times 7 = 64 - 28 = 36$

D > 0 and therefore we have two real solutions.

2.) Find the value of the discriminant and the number of real solutions of
2x^2+4x+2=0

Again, plug in the values from the equation into the formula of the discriminant.

${4}^{2} - 4 \times 2 \times 2 = 16 - 16 = 0$

D = 0 and therefore we have one real solution.

~ Hope this helps you.

Writing an equation of the form A/x+B)C to solve a word probl...

Margarita [4]

Answer:

(a) The equation is $7h-2=56$ .

(b) Trey gets approximately $8.29 for each hour of work.

Step-by-step explanation:

Given:

Number of hours Trey works = 7

Amount of money he put aside for mom = $2

Total Amount he keeps each day = $56

We need to find the amount he gets for each hour.

Let 'h' represent the amount (in dollars) Trey gets paid each hour.

Solving for part (a).

We need to write the equation to find the amount he gets paid for each hour.

Now we can say that;

Total Amount he keeps each day is equal to Number of hours Trey works multiplied by the amount he gets paid for each hour minus Amount of money he put aside for mom.

framing in equation form we get;

$7h-2=56$

Hence the equation is $7h-2=56$ .

Solving for part (b).

we need to solve the above equation to find the amount he gets paid for each hour.

On solving the equation we get;

Adding both side by 2 we get

$7h-2+2=56+2\\\\7h=58$

Now Dividing both side by 7 using Division Property we get;

$\frac{7h}{7} = \frac{58}{7}\\\\h \approx \$8.29$

Hence Trey gets approximately $8.29 for each hour of work.
