I wouldn't say that. It looks to me like you've absolutely got it ... almost.
A). Your fraction is correct. But it's not in simplest form like they want it.
Reduce 18/45 to simplest form. Hint: Divide top and bottom by 9 .
B). They want the percentage that's the same as 18/45 .
Do you remember how to change a fraction to percent ?
A fraction is just a short way to say "division".
" 18/45 " means " 18 divided by 45 ".
Do the division. To change the quotient into percent, multiply it by 100 .
(Same as moving the decimal point 2 places to the right.)
Round it the nearest whole number, if it isn't already a whole number.
C). Again, your fraction is correct, but it isn't in simplest form.
Reduce 27/45 to simplest form. Hint: Divide top and bottom by 9 again.
D). Change this fraction to percent, just like you did for the female fraction.
(Do the division that the fraction says, and multiply the quotient by 100.)
(Round to the nearest whole number percent if it isn't already.)
You already did the technical stuff. I just added some mechanical things.
Answer:
The equation is;
y = -2x - 3
Step-by-step explanation:
If two lines are parallel, then they have an equal value of slope
Mathematically we can generally have the equation of a line written as;
y = mx + c
where m
is slope and c is the y-intercept
In the case of the equation given, the slope of the line is -2
So technically, we want to get the equation of a line that has a slope of -2 and it passes through (2,-7)
The point-slope form can be written as;
y-y1 = m(x-x1)
So the equation we want to get is;
y-(-7) = -2(x-2)
y + 7 = -2x + 4
y = -2x + 4 - 7
y = -2x - 3
Check the picture below.
bearing in mind the a solution is where both graphs intersect.
Answer:
See explanation
Step-by-step explanation:
Triangle ABC ahs vertices at points A(-4,-4), B(-1,-2) and C(-1,-4).
<u>1 way:</u> First reflect this triangle across the y-axis to form the triangle A''B''C'' which vertices are at points A''(4,-4), B''(1,-2) and C''(1,-4).
Then translate this triangle 7 units up to form the triangle A'B'C' with vertices:

<u>2 way:</u> First translate this triangle 7 units up to form the triangle A''B''C'' which vertices are at points A''(-4,3), B''(-1,5) and C''(-1,3).
