Answer: -6/7

Step-by-step explanation:

3(5f+2)-f=2(-3)

  15f+6-f=-6 ⇔ distributive property

    14f+6=-6 ⇔ subtract f from 15f

        14f=-12 ⇔ subtraction property of equality (subtract 6 on both sides)

            f=-12/14 ⇔ division

            f=-6/7

Hope this helps!! :)

Please let me know if you have any question or need further explanation

Answer:

14f =-12

Step-by-step explanation:

3×5f+ 3×2-f = 2×-3

15f - f + 6 = -6

14f= -6

Complete the slope-intercept form of the linear equation that represents the relationship in the table.
nevsk [136]

According to the given table, the slope-intercept equation of the line is given by:

y = -2x + 1

The equation of a line, in <em>slope-intercept</em> form, is given by:

y = mx + b

In which:

  • The slope is m.
  • The intercept is b.

In this problem, we are given two points, (3,-5) and (-2,5).

  • The slope is given by <u>change in y divided by change in x</u>, hence:

m = \frac{5 - (-5)}{-2 - 3} = -2

Hence:

y = -2x + b

Point (3,-5) means that when x = 3, y = -5, which is used to find b.

y = -2x + b

-5 = -2(3) + b

b = 1

Hence, the equation of the line is:

y = -2x + 1

Use the discriminant to describe the roots of each equation. Then select the best description.
Marrrta [24]
Let's find the discriminant of <span>x^2+9x+14=0.  Here, a=1, b=9 and c=14.

The discriminant is b^2-4ac.  Substituting the above numeric values,
                                9^2-4(1)(14) = 81-56 = 25

The sqrt of 25 is 5.  Thus, your polynomial has two unequal, real roots.

Off the point example:  If the discriminant were zero, your poly would have two real, equal roots.</span>
