Before the fraction: -1/2, i have a negative sign
use y=mx+b
3=-1/2(2)+b
3+1=-1+b+1
4=b
check your work
0=-1/2x+4
0+4=-1/2x
(4)÷(-1/2)=(-1/2x)÷(-1/2)
-2=x
another pair is (-2,0) use this to figure out the other points, and/or the points you have in the multiple choice.

Angle e measures 126LaTeX: ^\circ∘. What is the measure of LaTeX: \angle∠h?
Oksana_A [137]

Option C: 126° is the correct answer

Step-by-step explanation:

When two lines intersect, the four angles are formed. The angles vertically opposite with same vertex are called vertical opposite angles.

The opposite vertical angles are equal.

In the given figure, the pairs of vertically opposite angles are e,h and f,g.

Given

∠e = 126°

The measurement of e and h will be equal as they are vertically opposite

So,

m∠e = m∠h

m∠h = 126°

Hence,

Option C: 126° is the correct answer

Use the row of numbers shown below to generate 12 random numbers between 01 and 99. 11097, 51877, 41665, 78465, 79932, 54899, 72
Nikolay [14]

The suitable numbers are:

11  09  75  18  77  41  66  57  84  65  79  93

Step-by-step explanation:

The random number line is used to generate random numbers between the given range

As the numbers have to be chosen  between 01 to 99, two digit pairs will be made.

Every time a pair is chosen, it is checked whether it falls in the range or not. If it falls in the range, it is selected otherwise the number is ignored.

So,

Given random number line is:

11097, 51877, 41665, 78465, 79932, 54899, 72970, 71789

The pairs will be:

11  09  75  18  77  41  66  57  84  65  79  93  25  48  99  72  97  07  17 89

Hence,

The suitable numbers are:

11  09  75  18  77  41  66  57  84  65  79  93

Keywords: Random number line, statistics

Ten times the sum of half a number and 6 is 8
Genrish500 [490]

" · " - times

" + " - sum

n - a number

0.5n - half a number

10 · (0.5n + 6) = 8     |use distributive property

(10)(0.5n) + (10)(6) = 8

5n + 60 = 8     |substract 60 from both sides

5n = -52    |divide both sides by 5

n = -10.4

What are the roots of the quadratic equation below?<br> x2 + 2x= -5
muminat

Answer:

No real root.

Complex roots:

x = -1 \pm 2i

Step-by-step explanation:

x^2 + 2x = -5

x^2 + 2x + 5 = 0

There are no two integers whose product is 5 and whose sum is 2, so this trinomial is not factorable. We can use the quadratic formula.

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

x = \dfrac{-2 \pm \sqrt{2^2 - 4(1)(5)}}{2(1)}

x = \dfrac{-2 \pm \sqrt{4 - 20}}{2}

x = \dfrac{-2 \pm \sqrt{-16}}{2}

Since we have a square root of a negative number, there are no real roots. If you have learned complex numbers, then we can continue.

x = \dfrac{-2 \pm 4i}{2}

x = -1 \pm 2i
