Answer:

x = -12/6 = -2

x = -18/6 = -3

Step-by-step explanation:

The zeros in an equation is the same thing as the x's.

3x²+15x+18 = 0 (Where a = 3, b = 15, c = 18)

One thing you could do to find the answer is use the quadratic formula:

x = (-b ± √(b²-4ac))/2a =

(-15 ± √15² - (4*3*18))/2*3 =

(-15 ± √225 - 216)/6 =

(-15 ± √9)/6 =

(-15 ± 3) / 6.

To find the first x we need to do (-15 + 3) / 6 and to find the second x we need to do (-15-3) / 6.

x = -12/6 = -2

x = -18/6 = -3

If you do the problem in the order of operations (PEMDAS), it should be B. 18

This table gives a few (x,y)(x,y)left parenthesis, x, comma, y, right parenthesis pairs of a line in the coordinate plane. -28 -

Serhud [2]

Answer:

The y-intercept is y = 2

Step-by-step explanation:

A linear function has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept, which is the value of y when x = 0.

We are given these three points:

(-28, -54)

(-21, -40)

(-14, -26)

We use two of them to build a system, to find values for m and b.

(-28, -54)

This means that when $x = -28, y = -54$

$y = mx + b$

$-54 = -28m + b$

$28m = b + 54$

$m = \frac{b + 54}{28}$

(-21, -40)

This means that when $x = -21, y = -40$

$y = mx + b$

$-40 = -21m + b$

$-40 = -21\frac{b + 54}{28} + b$

$-40 = \frac{-21b - 1134 + 28b}{28}$

$7b - 1134 = -40*28$

$7b = 14$

$b = \frac{14}{7}$

$b = 2$

The y-intercept is y = 2

Hendrick wants to enlarge a photo that is 4 inches wide and 6 inches tall and large photo keeps the same ratio how tall is the e

EastWind [94]

Write out the ratio. 12/x=4/6. From here you can see that to get from 12 to 4, you divide by three. To find x, multiply 3 to 6. Your answer is 18 inches.

2. A university admitted 100 students who transferred from other institutions. Of these students, 34 transferred from two-year c

antoniya [11.8K]

Answer:

So probability will be 0.34

Step-by-step explanation:

We have given that a university admitted 100 students

In which 34 students are from two year community program

25 students are from private four year institution

And rest that is 100-34-25 = 41 students from public four year institutions

Number of ways for selecting two students from two year community program that is, from 34 students

$=^{34}C_2$

And the number of ways in selecting the 2 students from total student $=^{100}C_2$

So probability will be $P=\frac{^{34}C_2}{^{100}C_2}=\frac{17}{50}=0.34$
