Graph the liney= -5x+2
IRISSAK [1]

To answer this question, we can find the intercepts of the line, since they are two points easy to identify on the coordinate plane. To find them, we can proceed as follows:

<h2>Finding the x-intercept</h2>

The x-intercept is the point where the line passes through the x-axis. At this point, y = 0. Then, we have:

y=-5x+2\Rightarrow y=0\Rightarrow-5x+2=0

Then, to solve the equation for x, we can subtract 2 from both sides of the equation, and then we have to divide both sides by -5 as follows:

-5x+2-2=-2\Rightarrow-5x=-2\Rightarrow-\frac{5}{-5}x=-\frac{2}{-5}x=\frac{2}{5}=0.4

Then, the x-intercept is (2/5, 0) or (0.4, 0). This is one point to graph the line.

<h2>Finding the y-intercept</h2>

The y-intercept is the point where the line passes through the y-axis. At this point, the value for x = 0. Then, we can proceed as follows:

y=-5x+2\Rightarrow x=0\Rightarrow y=-5(0)+2\Rightarrow y=2

Then, the y-intercept is (0, 2).

<h2>Graphing the line</h2>

We know that a line is defined by two points, and we have found two points for this line: (2/5, 0) and (0, 2). Then, we have:

We can appreciate that the line has a negative slope and that we have the two intercepts for the line (0, 2) and (0.4, 0).

y=x²-10x-7

a>0 so we will be looking for minimum

x=-b/2a=10/2=5

y=25-50-7=-32

Answer: (5;32)

y=-4x²-8x+1

а<0 so we will be looking for maximum

х=-b/2a=8/-8=-1

у=4+8+1=13

Maximum point (-1;13)

Mike and Ike are experts at pitching horseshoes. 70% of Mike's tosses are ringers. 67% of Ike's tosses are ringers. Suppose Mike
ahrayia [7]
Mike tosses 70%
Ike tosses 67%
Both tosses 50%

<span>Which of the following is closest to the probability that Ike's proportion is ringers is higher than Mike's for those tosses?
</span>
P(m) = 70/100
P(i) = 67/100
P(b) = 50/100

= P(b) * P(i) 
= 50/100 * 67/100
= 0.335

The correct answer is letter D) 0.3745.
