Answer:

Step-by-step explanation:

Slope= x÷y

So. m= -2

For y intercept consider equation

y= 2x-8

y=mx+c where c is y intercept

Hence y intercept is 8 as slope is negative

Answer:

m = 2 and b = -8.

Step-by-step explanation:

One of the most commonly used equations of straight lines is y = mx + b, where m is the slope and b is the y-intercept.

Comparing the given y = 2x - 8 to y = mx + b, we see that m = 2 and b = -8.

Answer:

11 sq.ft

Step-by-step explanation:

∅= 80×π/180= 4π/9

area= 1/2 × r²× ∅

= 1/2 × 16 × ∅

= 8∅

=8×(4π/9)

= 32π/9

= 11.17 ~11

The base of a basketball goal has the shape of a rectangular pyramid. The base of the goal must be filled with sand so the goal
mart [117]

Answer:

  B.  15 ft^3

Step-by-step explanation:

The volume of a pyramid is given by the formula ...

  V = (1/3)Bh

where B represents the area of the base, and h represents the height.

The base is apparently a rectangle, so its area is the product of its length and width:

  B = L·W = (4.5 ft)(4 ft) = 18 ft^2

Then the volume is ...

  V = (1/3)(18 ft^2)(2.5 ft) = 15 ft^3

15 cubic feet of sand will be needed to fill the base.

Find the value(s) of "k" that will cause the equation 4x^2 +kx + 4 to have one real solution.
Andreas93 [3]

Answer:  k = {8, -8}

<u>Step-by-step explanation:</u>

In order for a quadratic equation to have exactly one solution, the discriminant must equal zero.       →        b² - 4ac = 0

  4x² + kx + 4 = 0

  ↓       ↓      ↓

a=4    b=k    c=4

b² - 4ac = 0

k² - 4(4)(4) = 0

k²             = 64

           k = √64

           k = ± 8

If x = -4, calculate 2x squared - 5
Varvara68 [4.7K]
You just substitute the value of x in the given equation:


f(x) = 2x^2 - 5

f(-4) = 2 (-4)^2 -5 = 27

f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
