What is the value of "c" in the quadratic equation 3x 2 + 5x + 7 = 0?
Nutka1998 [239]

Answer:

7

Step-by-step explanation:

The quadratic equation looks like:

ax + by + c = 0

"c" is the variable that stands for the "constant", or the number that does not have an extra variable attached, and so is "unchanging". In this case, your answer is 7, which is the constant of the equation. Once defined, the number cannot be changed.

Write a quadratic relation in the form y = ax2 + bx + c with roots 4 and - 3 and
earnstyle [38]

Answer:

2x²-2x-24

Step-by-step explanation:

Something has roots of 4 and -3 we can write

(x-4)(x+3)

We then attach a constant, a that will ensure that it passes through the correct point

a(x-4)(x+3)

now plug in the numbers and solve for a

a(3-4)(3+3)= -12

a(-1)(6)= -12

-6a= -12

a=2

So we have

2(x-4)(x+3)

and now it's just a matter of mulitplying/simplifying things

(x-4)(x+3)= x²-x-12

2(x²-x-12)= 2x²-2x-24

Erika worked 14 hours last week and 20 hours this week. If she earns $9 per hour, how much did she earn during these two weeks?
ozzi

we know that

Erika earns \$9 per hour

so

By proportion

Find how much she earn during the total hours of two weeks

The total hours of two weeks is equal to

14+20=34\ hours

\frac{9}{1} \frac{\$}{hour} =\frac{x}{34} \frac{\$}{hours} \\ \\x=34*9 \\ \\x=\$306

therefore

<u>the answer is</u>

\$306

(y 3 - y2 + y + 3) = (y + 1)
kkurt [141]

Answer:

y = -1

Step-by-step explanation:

Find roots (zeroes) of :       F(y) = y3-y2+2

Polynomial Roots Calculator is a set of methods aimed at finding values of  y  for which   F(y)=0  Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  y  which can be expressed as the quotient of two integersThe Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading CoefficientIn this case, the Leading Coefficient is  1  and the Trailing Constant is  2.
