Answer:

-1

Step-by-step explanation:

First, lets combine like terms (negatives with negatives)

-3 + -2 = -5

4-5 simplified equations from before

4-5= -1

so your answer is -1

<1 and <2 are supplementary angles. m <1 is 4y+7, and m<2 is 9y+4. Find m<2.
Yuliya22 [10]

Okay, so supplementary angles = 180 degrees.

Starting equation : 4y + 7 + 9y + 4 = 180

Combine like terms : 13y + 11 = 180

Subtract 11 from both sides : 13y = 169

Divide 13 from both sides : y = 13

Insert y value into original m<2 equation : 9(13) + 4

Solve : 121 degrees


If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.

4(13) + 7 = 59

59 + 121 = 180

Find the roots of the following polynomial equations: 1. y = 2x2 + 3x - 5​
nydimaria [60]

Answer:

Step-by-step explanation:

y=2x^2+3x+5\\

Using the quadratic formula:

\frac{-3+-\sqrt{9-4(2)(5)}}{2(2)} = \frac{-3+-\sqrt{-31}}{4}

Since the discriminant is negative, -31, there are no real roots

Your plant runs two assembly lines. The first line produces 1,250 units a day and the second produces 2,825 units a day. What is
Step2247 [10]

Answer:

\frac{50}{113}

Step-by-step explanation:

The ratio is simply the division of one by another (and simplification).

Hence, <u>the ratio of production of the first line to the second line</u> is 1250 divided by 2825. So,

Ratio = \frac{1250}{2825}=\frac{50}{113}
