0=8x^2+8x-21 in (x-p)^2=q form

Mathematics
1 answer:
Makovka662 [10]3 years ago
7 0

Step-by-step explanation:

8x² + 8x - 21 = 0

8(x² + x) - 21 = 0

8(x + 0.5)² - 23 = 0

8(x + 0.5)² = 23

(x + 0.5)² = 23/8.

F(h)=-6h-2/3 Find f(-3)
solmaris [256]
<span>f(h) =  -6h - 2/3

 For f(-3), anywhere we see h in the equation we substitute -3.

f(-3) =  -6(-3) - 2/3 = 18 -2/3 =  17  1/3.

f(-3) =  17  1/3      or      52/3.

So that's our answer.</span>

In the 30-60-90 triangle below, side s has a length of ___ and side q has a length of ___.
larisa [96]

Answer:

The answer is D.

Step-by-step explanation:

The side lengths for this special triangle is represented with x, x\sqrt{3} , and 2x

if the side length that sees 90 degrees is 10 (2x and x = 5 in this case)

so s (the side length that sees 30 degrees) is = 5

and q (the side length that sees 60 degrees) = 5\sqrt{3}

For what values of m does the graph of y 3x2 7x m have two x intercepts
Phoenix [80]

The graph has a minimum point and is a parabola. Therefore, change the minimal value in the formula y = 3x2 + 7x + m. The value at the minimum point must be smaller than zero because the graph has two x-intercepts. The minimum point of the graph, which is a parabola, lies at x=-b/2a = -7/6.

What is Graph?

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.

The graph has a minimum point and is a parabola.

Therefore, change the minimal value in the formula y = 3x^2 + 7x + m.

The value at the minimum point must be smaller than zero because the graph has two x-intercepts.

The graph is a parabola, with x=-b/2a = -7/6 as the minimum.

3(49/36) – 49/6 + m < 0

49/12 – 49/6 + m < 0

(49-98)/12 + m < 0

-49/12 + m < 0

m < 49/12
