Answer:

Hello My Friend! The correct answer its double root.

Step-by-step explanation:

In this equation, if we applie the a, b and c coefficients (a=1, b=4, c=4) ind the Bhaskara, the final result will be 4 for both cases. x'=4 and x''=4. It happens because the number of theta is equal to 0. So, both roots will be the same number.

Solve the equation -5(s+30)=-17
zzz [600]

Answer:

s = -133/5 = -26.600 ⬇️

Step-by-step explanation:

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (0 -  5 • (s + 30)) -  -17  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -5s - 133  =   -1 • (5s + 133)

Equation at the end of step  3  :

 -5s - 133  = 0

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    -5s-133 = 0

Add  133  to both sides of the equation :

                     -5s = 133

Multiply both sides of the equation by (-1) :  5s = -133

Divide both sides of the equation by 5:

                    s = -133/5 = -26.600

One solution was found :

                  s = -133/5 = -26.600

Y = -x + 2 identify the slope and y intercept and graph
lys-0071 [83]

Answer:

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

What values of a and b make the equation true? StartRoot 648 EndRoot = StartRoot 2 Superscript a Baseline times 3 Superscript b
kramer

Option C: a=3, b=4 is the value of a and b

Explanation:

Given that the expression \sqrt{648}=\sqrt{2^a\times3^b}

We need to determine the value of a and b

Let us consider the term \sqrt{648} and take the prime factorization of the term 648

Thus, we have,

648 divides by 2,

648=2 \cdot 324

324 divides by 2,

648=2 \cdot 2 \cdot 162

162 divides by 2,

648=2 \cdot 2 \cdot 2 \cdot 81

81 divides by 3,

648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 27

27 divides by 3,

648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 9

9 divides by 3,

648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 3 \cdot 3

Thus, we have,

\sqrt{648}=\sqrt{2^{3} \cdot 3^{4}}

Therefore, equating the powers of 2 and 3, we get,

a=3, b=4

Hence, the value of a and b is 3 and 4

Thus, Option C is the correct answer.
