Answer:

0 real roots

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the discriminant is

Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then the roots are not real

- 9x² + x - 7 = 0 ← is in standard form

with a = - 9, b = 1, c = - 7 , then

b² - 4ac = 1² - (4 × - 9 × - 7) = 1 - 252 = - 251

Since b² - 4ac < 0 then the equation has no real roots

Answer:

4 pairs of sock and a little bit of left over change.

Step-by-step explanation:

24.95 + 5.95x = 50

-24.95                -24.95

5.95x=25.05

/5.95   /5.95

x = 4.21

We drop the 0.21 because you cant have 0.21 pairs of socks and we get:

x=4

Answer:

About 4 pairs.

Step-by-step explanation:

50.00-24.95=25.05

5.95x5=29.75 (that is more the 25.05, so no.)

5.95x4=23.80 (Its a little bit less but not higher than the number we have left to spend.)

Answer:

f(x) underwent a downward vertical translation to get g(x)

Step-by-step explanation:

here, we want to describe a transformation

Looking at the two equations, we can notice that the difference between the two is the -17

Practically, we have this difference as 17 subtracted from the second equation

what this mean is that there is a downward vertical translation of the first graph by 17 units to get the second graph

Answer:

x = 12

Step-by-step explanation:

For trapezoid DEFG to be isosceles, measures of it's base angles must be equal.

i.e.

[tex] m\angle E =m\angle F[/tex]

[tex] (5x+15)\degree =(7x - 9)\degree [/tex]

5x + 15 = 7x - 9

5x - 7x = - 15 - 9

-2x = - 24

2x = 24

[tex] x = \frac{24}{2} [/tex]

x = 12

The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.

A credit card is a method of payment that is given to customers so they may pay a merchant for products and services depending on the debt they have accumulated.

Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125.

The distinction between the installment made and the charges done will be given as,

Difference = $200 - $125

Difference = $75

Partition as far as possible by this distinction to find the number of months that Zea can proceed with this example until she contacts her credit limit.

⇒ $2,000 / $75

⇒ 26.667 ≈ 27

The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.
