Answer:
y=-9/2, x=7
Step-by-step explanation:
You can solve this via substitution. First solve for x in terms of y in one of the equations given. Lets use the first one:
25+4y=x
Now plug 25+4y in for x in the second equation
3(25+4y)-2y=30
75+12y-2y=30
75+10y=30
10y=-45
y=-9/2
Plug this into the first equation:
25-x=-4(-9/2)
25-x=18
x=7
Is there anything that explains what C and n are?
Answer:
I apologise for how scruffy it looks, i didnt have a book or pen with me so this is the best i can do.
Answer:
Not an exponential function. The exponent is a constant.
Step-by-step explanation:
An exponential function has the variable in the exponent. This function raises the variable to a fixed power, so it is not an exponential function.
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
y = 4/3x - 5
Comparing with the general equation above
Slope/ m = 4/3
Since the lines are parallel their slope are also the same
So we have
Slope of parallel line = 4/3
Equation of the line using point (−6,−5) and slope 4/3 is
