Answer:
C
Step-by-step explanation:
In order to write the equation, you need to identify the slope and y-intercept.
1) the y intercept is what y is when x=0. According to the table, it is -2.
2) the slope is the change in the y values over the change in the x values. Notice that the y values are increasing by one for every increase in 1 in the x values, so the slope is 1/1 or 1.
3) we can then put those values into slope-intercept form which is y=mx+b where m is the slope and b is the intercept.
4) so the equation is y=(1)x-2 or y=x-2 (they are the same)
Answer:
$30
Step-by-step explanation:
Total amount paid by the hire purchase scheme:
$60 + 6 * $45 = $60 + $270 = $330
Total amount paid in just the cash price:
$300
Difference:
$330 - $300 = $30
All we have to do is set this up!
we know that all he practiced altogether for 15 and 1/3 hours
so lets put that down so far
1
15 ----- =
3
and he says that the first week he played 6 and 1/4 hours on the first week
now lets add that
1 1
15 ----- = 6 ----- +
<span> 3 4
</span>now we also know that he played 4 and 2/3 hours on the first week
now lets add that
1 1 2
15 ----- = 6 ----- + 4 ----- +
<span> 3 4 3
</span>we arent finished yet!
now the third week we dont know how long he played so we are going to put x in its place
1 1 2
15 ----- = 6 ----- + 4 ----- + x
<span> 3 4 3
</span>and there is your answer! finally...
hope this helps:) MARK AS BRAINLIEST!!!

Answer:
The standard parabola
y² = -18 x +27
Length of Latus rectum = 4 a = 18
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given focus : (-3 ,0) ,directrix : x=6
Let P(x₁ , y₁) be the point on parabola
PM perpendicular to the the directrix L
SP² = PM²
(x₁ +3)²+(y₁-0)² = 
x₁²+6 x₁ +9 + y₁² = x₁²-12 x₁ +36
y₁² = -18 x₁ +36 -9
y₁² = -18 x₁ +27
The standard parabola
y² = -18 x +27
Length of Latus rectum = 4 a = 4 (18/4) = 18
