Which of the following cannot be solved using the quadratic formula?
VLD [36.1K]

Answer:

C

Step-by-step explanation:

Quadratic formula is used only to solve the quadratic equations .

Means the equation of the form

ax^{2} +bx+c=0

In this the x^2 part is must because that only makes the equation a quadratic.

Looking at the four options given to you , only the option C has the missing x^2 term, which makes it a linear equation and hence the quadratic formula cannot be applied there .

So the right option for your question with the quadratic formula is

option

C

Lina20 [59]

Answer:

\large\boxed{B)\ -\dfrac{1}{2}}

Step-by-step explanation:

-(-6x-5)=4(5x+3)\qquad\text{use the distributive property}\\\\-(-6x)-(-5)=(4)(5x)+(4)(3)\\\\6x+5=20x+12\qquad\text{subtrac 5 from both sides}\\\\6x=20x+7\qquad\text{subtract 20x from both sides}\\\\-14x=7\qquad\text{divide both sides by (-14)}\\\\x=-\dfrac{7}{14}\\\\x=-\dfrac{1}{2}

Need help, will mark brainliest plus 50 points.
uranmaximum [27]

Answer:

Step-by-step explanation:

To write the inequality, we need to first caculate the amount of money that Lia would ACTUALLY earn each week and compare that to her goal of $600.

We cannot actually get the amount of money that Lia would get because we don't know her sales so we will represent the sales with a X.

450+ X(5%).  -This the amount of money she would egt from her sales. We need to also figure out 5% of 450 to solve the next part of the equation. That is $22.5. 600-450=150/22.5= 6.6666- which is about 7 sales.
