-3 V180(the V is a radical symbol)How would I write this in a simple radical form?

1 answer:

7 0

$\bf -3\sqrt{180}\qquad \begin{cases} 180=&2\cdot 2\cdot 3\cdot 3\cdot 5\\ &2^2\cdot 3^2\cdot 5\\ &(2\cdot 3)^2\cdot 5\\ &6^2\cdot 5 \end{cases}\implies -3\sqrt{6^2\cdot 5}\implies -18\sqrt{5}$

Given the equation y = -3x +1/2 , what is the y-intercept?

pychu [463]

y intercept = 1/2

Step-by-step explanation:

Step 1:

Formula y=mx+b in Slope Intercept form( whereas m= slope of the given equation, b= y intercept)

Step 2:

Comparing the given equation y = -3x + 1/2

we get m=-3(Slope) and y-intercept b=1/2

Solve the equation by factoring. 8x^2+10x-7=0 What is the solution set?

nydimaria [60]

Answer:

$\large \text{$x_1$}=-\dfrac{7}{4}, \large \text{$x_2$}=\dfrac{1}{2}$

Step-by-step explanation:

Given: 8x² + 10x - 7 = 0

When factoring trinomials of the form ax² + bx + c:

multiply the leading coefficient and the last term.
find the product factors that add to give you the coefficient of the middle term.
rewrite the polynomial with those factors replacing the middle term.

1. Split the middle term:

⇒ 8 × -7 = -56 [multiply the leading coefficient and the last term]

⇒ 14, -4 [find the product factors that add to the middle term's coefficient]

⇒ 8x² + 14x - 4x - 7 = 0 [rewrite with those factors replacing the middle term.]

2. Factor by grouping:

⇒ 8x² + 14x - 4x - 7 = 0 [factor out 2x]

⇒ 2x(4x + 7) - 4x - 7 = 0 [factor out -1 or the negative sign]

⇒ 2x(4x + 7) -1(4x + 7) = 0 [factor out 4x + 7]

⟹ (4x + 7)(2x - 1) = 0

3. Separate into 2 cases:
