Answer: A

Step-by-step explanation:

The answer is A.

y≤-2x+3 .... (1)

y≤x+3 ..........(2)

In the system is inequality above, the f(x) is a negative graph while the g(x) is a positive graph.

The two function have different gradients ( slope) so, the will surely have the intersecting portion or area where f(x) and g(x) have shading in common which is labeled AB.

What is an equation of a line that passes through the point (10,5) and is perpendicular to the line whose equation is y=5/4x-2?
Maurinko [17]

y = mx + b

slope(m) = -4/5

(10,5)...x = 10 and y = 5

now sub into the formula and find b, the y int

5 = -4/5(10) + b

5 = -40/5 + b

5 = -8 + b

5 + 8 = b

13 = b

so ur perpendicular equation is : y = -4/5x + 13 <===

Hope this helps!

What are the exact solutions of x^2 − 3x − 7 = 0?
bulgar [2K]

<u>Given</u>:

The given equation is x^{2} -3x-7=0

We need to determine the exact solutions of the equation.

<u>Exact solution:</u>

The exact solution of the equation can be determined by solving the equation using quadratic formula,

x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

From the equation the values are a = 1, b = -3 and c = -7

Thus, substituting these values in the equation, we get;

x=\frac{-(-3) \pm \sqrt{3^2-4(1)(-7)}}{2(1)}

x=\frac{3 \pm \sqrt{9+28}}{2}

x=\frac{3 \pm \sqrt{37}}{2}

Thus, the exact solutions of the given equation is x=\frac{3 \pm \sqrt{37}}{2}

Hence, Option A is the correct answer.

Can you help me with number 5?
Verizon [17]

We can divide that up into two rectangles, say the bottom one 8 feet wide and 2 feet high.  That leaves 5.5 by 6-2=4 feet for the other.

Cost = price × area = 2.25(8×2 + 5.5×4) = $85.50

Answer: $85.50
