Slope intercept form is y=MX+b.
M is the slope, x is the x intercept, and b is the y intercept

the slope is
\frac{ - 2}{1}
An intercept is where the formula crosses the axis. therefore, the x intercept is .5, and the y intercept is 1
so the point slope formula is
y =  \frac{ - 2}{1} 0.5 + 1

The slope = -1/2  and y intercept is at y = 1

The answer is y = -1/2 x + 1

A bag contains nine red balls, four green balls, and fifteen yellow balls. What is the probability of pulling out one red ball?
Aleksandr [31]

Answer:

32.1%

Did you type something in wrong?

Step-by-step explanation:

9+4+15=28 total balls

9=total red balls

total red balls/total balls= probability of pulling out one red ball

9/28

9÷28=32.1%

Can u guys help me please with 5,6,7,8

An explanation for this is that a straight line has a angle degree value of 180. Therefore if you draw the line that creates a 139 degree angle, the rest of the line would have an angle measurement of what is left of the 180 degrees. So to get x you would start with the 180 degree straight line value and subtract the 139 degrees of the line that divides it. so equation is:
180 - 139 = x
And and you get 41 degrees.
(To word this another way the two angles of x and 139 have to add up to the straight line of 180 degrees. Therefore another equation could be:
139 + x = 180
which is basically the same equation but might be easier explanation for some to understand.)


questions 7 and 8 are the same but instead of straight line with 180 degrees, you start with right angle with 90 degrees. Therefore x and the 18 degree angle have to add up to 90 degrees making an equation of:
x + 18 = 90
Or
x = 90 - 18
answer would be
x = 7w

Dave, Frank, and Kathy can process 1,300 catalog orders per day when all three of them are working. Dave and Frank can do 780 or
Natalija [7]
(1) x+y+z=1300
(2) x+y=780 => x = 780 - y
(3) y+z=850 => z = 850 - y

Replace x and z with y in function (1)

780 - y + y + 850 - y = 1300
1630 - y = 1300
y = 330

Therefore, x = 780 - y = 780 - 330 = 450
z = 850 - y = 850 - 330 = 520

Dave can do 450 catalog orders per day
Frank can do 330 catalog orders per day
Kathy can do 520 catalog orders per day

Marrrta [24]
Add 5% to the 15% you get 20%. now multiply 476 by 1.20 to get the total cost
476 \times 1.20
