Lines a and b in the figure above are parallel. What is the value of p?
elena-s [515]
It will be c- 20:
4q and 2(q+30) have to equal the same therefore q=30 which makes both these equations equal.
3p + 4q then have to equal 180 as they are on a straight line so you know q=30 so 4x30=120 so 180-120=60
Then 60/3=20 and that is your answer.
Hope this helps :)

Is the following relation a function?<br><br> x y<br> 1 −2<br> 1 −3<br> 2 1<br> 3 −2
vagabundo [1.1K]

Answer:

It is not a function!

Step-by-step explanation:

It is not a function!

A function can't have two y-values assigned to the same x-value. In this case, you can se that for x=1 we have two y-values, which are y= -2 and y= -3.

We can have have two x-values assigned to the same y-value, that's why it's okay that for x=1 and x=3 we have the same y-value y=-2

Rachel earned \$34$34 in 44 hours at her job today. She wants to know how much she could earn (e)(e) tomorrow if she works 1010
kari74 [83]

Answer:

<em>Rachel will earn $85 in 10 hours.</em>

Step-by-step explanation:

Rachel earned $34 in 4 hours at her job today.

Suppose, she will earn x dollar in 10 hours tomorrow.

So, <u>according to ratio of 'dollar' and 'hours'</u>, the equation will be.....

\frac{34}{4}=\frac{x}{10}

After cross multiplying, we will get.....

4x= 34*10\\ \\ 4x= 340\\ \\ x=\frac{340}{4}=85

Thus, Rachel will earn $85 in 10 hours.

Find three consecutive odd integers such that the sum of the 1st and 2nd number is 344
olga2289 [7]

Answer:

three consecutive odd integers are.

171, 173, 175

Step-by-step explanation:

Let x be the first term of odd integer,

Therefore, the second consecutive odd integers = x+2

Similarly, the third consecutive odd integers = x+4

Given:

The sum of the first term and second term is 344.

first term + second term = 344

Here first term is x and second term is x+2.

x+(x+2)=344

2x+2=344

2x=344-2

x=\frac{342}{2}

x=171

Therefore, the first odd integers is 171.

And the second consecutive odd integers = x+2=171+2=173

Similarly, the third consecutive odd integers = x+4=171+4=175

X² <span>− 3x − 70=0
</span>x² + 7x - 10x − 70=0
x(x+7) - 10(x+7) = 0
(x+7)(x-10) = 0

x + 7 = 0   or   x - 10 = 0
x = -7              x = 10
