Factor 3y^2 + 5y - 12

Mathematics
1 answer:
mojhsa [17]3 years ago
7 0

Answer:

(3y - 4)(y + 3)

Step-by-step explanation:

Expression: <em>3y² + 5y - 12</em>

My preferred method of factoring is to find two numbers that add up to bx and has the product of acx² (when ax² + bx + c), substituting those numbers in for bx, and factoring that way. So here;

Numbers: <em>-4y, 9y</em>

Substitute: 3y² - 4y + 9y - 12

Factor: (3y - 4)(y + 3)

Answer:

m=-1

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Simply plug in 2 coordinates into the slope formula to find slope <em>m</em>:

m=\frac{0-(-2)}{-2-0}

m=\frac{0+2}{-2}

m=\frac{2}{-2}

The number of nuts in a can of mixed nuts is found to be normally distributed, with a mean of 500 nuts and a standard deviation
timofeeve [1]

Answer:

z = -2.85

Step-by-step explanation:

Since the number of nuts per can is normally distributed:

Mean number of nuts (μ)= 500 nuts

Standard Deviation (σ)= 20 nuts

X = 443 nuts

For any given number of nuts X, the z-score is given by:

z=\frac{X-\mu}{\sigma} =\frac{443-500}{20}\\z= -2.85

The z-score for this can of nuts with 443 nuts is -2.85.
