Has an x-intercept of (4,0) and a y- intercept of (0,-2)

Just to be different we'll start with intercept intercept form which says the line through x intercept (a,0) and y intercept (0,b) is

\dfrac x a + \dfrac y b = 1

Through (4,0) and (0,-2) that's

\dfrac{x}{4} + \dfrac{y}{-2} = 1

Multiply through by the common denominator of 4 for standard form:

x - 2y = 4

For slope intercept form we solve for y

-2 y = -x + 4

y = (1/2) x - 2

We see our slope is (1/2) and we go through (4,0) so point slope form is

y - 0 = (1/2)(x - 4)

y = (1/2)(x-4)

What is the value of x ?? If u cant see numbers let me know
Hoochie [10]

Answer:

X = 58°

Step-by-step explanation:

105° = (2x -11)°

105° + 11° = 2x

116°= 2x

Divide both sides by 2

X = 58°.

Using the inequity -16k-32>-48
3241004551 [841]

Answer:

k<1

Step-by-step explanation:

1. Add 32 to both sides

-16k-32+32>-48+32

2. Simplify

-16k>-16

3. Reverse the sign (You only reverse the sign if you are DIVIDING BY a negative.)

-16k/-16 = k

-16/-16 = 1

You're left with k < 1

Your number line graph should be an open circle at 1 going to the left.

The function f(x) = –x2 + 60x – 116 models the monthly profit, in dollars, a shop makes for repairing windshields, where x is th
Sholpan [36]

Answer:

A. We factor the equation to get: -(x-25)^2+361 In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361).  This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.

B. The x-intercepts are the values of x for which f(x) is 0.  This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44.  Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.

Step-by-step explanation:

f(x)=−(x2−60x+900−900)−116

f(x)=−(x−30)2+784

Maximum Profit=784

Vertex is (30, 784)

maximum profit is when x wind-shields are repaired.

−x2+60x−116=0

x2−60x+116=0

x2−2x−58x+116=0

x(x−2)+58(x−2)=0

(x−2)(x−58)=0

x=2,58

x intercepts are x=2, x=58

at these points there is no profit or loss.
