Rational. There’s nothing further that you can do with this problem

From the set {30, 42, 84}, use substitution to determine which value of x makes the equation true.

andre [41]

Answer:

42

Step-by-step explanation:

The correct choice is marked.

If you follow instructions, you will compute the quotient for each value in the set:

2520 ÷ 30 = 84

2520 ÷ 42 = 60 . . . . . the value we're looking for (we need go no further)

2520 ÷ 84 = 30

__

The easier way to solve the problem is to multiply the equation by x/60, so you have ...

2520 ÷ 60 = x

Then, you're doing one division instead of two or three.

2520 ÷ 60 = 42 = x

The parabola $y = ax^2 + bx + c$ is graphed below. Find $a+b+c$. (The grid lines are one unit apart.)

Ann [662]

If $x=0$ , then $y=a\cdot0^2+b\cdot0+c=5$ , so $c=5$ .

If $x=1$ , then $y=a\cdot1^2+b\cdot1+c=2$ , so $a+b+5=2$ or $a+b=-3$ .

If $x=2$ , then $y=a\cdot2^2+b\cdot2+c=1$ , so $4a+2b+5=1$ or $2a+b=-2$ .

We have

$a+b=-3\implies -a-b=3$

$(2a+b)+(-a-b)=-2+3$

$\implies a=1\implies b=-4$

So we end up with

$a+b+c=1+(-4)+5=\boxed{2}$

What is in extraneous solution to the equation b/b-7 - 2/b = 7/ b-7 ?

alexandr402 [8]

Answer:

b = 2 or b = 7

Step-by-step explanation:

b/(b-7) - 2/b = 7/ (b-7)

b * b - 2(b - 7) = 7 * b

b^2 - 2b + 14 = 7b

b^2 - 9b + 14 = 0

(b - 2)(b - 7) = 0

b - 2 = 0; b = 2

b - 7 = 0; b = 7

Answer

b = 2 or b = 7

Bryce tried to solve an equation step by step.

Aloiza [94]

$$c=\frac{1}{3}$

Solution:

Given equation is $\frac{8}{3}=3c+\frac{5}{3}$ .

To solve the equation by step by step.

Step 1: Given

$\frac{8}{3}=3c+\frac{5}{3}$

Step 2: Combine like terms together.

Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.

$\frac{8}{3}-\frac{5}{3}=3c$

Step 3: Subtract the fractions in the left side.

$\frac{3}{3}=3c$

⇒ $1=3c$$

Step 4: Divide both side of the equation by 3, we get

$\frac{1}{3} =\frac{3c}{3}$

$\frac{1}{3} =c$

Hence, the answer is $c=\frac{1}{3}$ .
