Brainliest pleeease!!!!
Ok sooooooo the line is at the y intercept at (0,-50)
And if u choose two points on the graph (solid points) likeeee…. (0,-50) and (20,-30)
Use rise/ run
Soooo u go up two units and right two units soooo 2/2!!! Simplified thats what?? Thats 1!!
And so.
Y=mx+b
Plug in a few numbers….
Y=1x-50
Aaaaand the slope is moooving up (how do I know??) because from the start which is (0,-50) it goes up. So that’s why the 1 is positive. It’d be negative if it’s going the other way.
Sorry if that made no sense but moral of the story, the answer is y=1x-50
The sum of interior angle is = 180(n-2) where n denotes the number of sides
so 1260° =180(n-2), n -2= 1,280/180=7, so n=7+2=9
the answer is <span>C. 9

Answer:
No they are not equal;
a = -13
Step-by-step explanation:
Here, we want to find the value of a
We are gong to use the ratio given
That will be;
a + 3/ 7 + a = 4/5
5(a + 3) = 4(7 + a)
15 + 3a = 28 + 4a
4a - 3a = 15-28
a = -13
Answer:
x = 2 ± (i)√5 (Answer b)
Step-by-step explanation:
x²-4x+9=0 can be solved in a variety of ways; the first two that come to mind that are also appropriate are (1) completing the square and (2) using the quadratic formula.
Completing the square is fast here:
Rewrite x²-4x+9=0 as x²-4x +9=0
Identify the coefficient of the x term: it is -4
Take half of that, obtaining -2
Square this result, obtaining 4
Add 4 to x²-4x +9=0, in the blank space in the middle, and then subtract 4: x²-4x +4 -4 +9=0
Rewrite x²-4x +4 as the square of a binomial:
(x - 2)² - 4 + 9 = 0 → (x - 2)² = -5
Take the square root of both sides: x - 2 = ±√(-5) = ± (i)√5
Then x = 2 ± (i)√5
Answer:
<u>4.63 as simplified fraction is</u>
<u>463/100</u>
Step-by-step explanation:
<em>4.63 as a fraction in simplest form</em>
<em>To convert 4.63 to fraction, follow these steps:</em>
<em />
<em>First write down the decimal number divided by 1 like this:</em>
<em />
<em>4.63/1</em>
<em />
<em>As we have 2 digits after the decimal point in the numerator, we need to multiply both the numerator and denominator by 10² = 100, so that there is no decimal point in the numerator</em>
<em />
<u><em>4.63 × 100</em></u>
<em> 1 × 100</em>
<em> = </em>
<em>463/100</em>
<em />
<em>As the numerator is greater than the denominator, we have an improper fraction, so we can also express 4.63 as a mixed number, thus 463/100 is equal:</em>
<em />
<em>4 63/100</em>
