The equation has to be set to something otherwise it is just an expression. I will assume that you mean 3x+60=0 in which case x equals negative 20
<span> y = 2/7 x - 1/7
slope = 2/7
</span><span>perpendicular lines, slope is opposite and reciprocal
</span>so slope of new line = -7/2
<span>passes through the point (9,-32)
</span><span>slope-intercept form: y = mx + b
so
b = y - mx
b = -32 - (-7/2)(9)
b = -32 + 63/2
b = -1/2
equation in </span>slope-intercept form:
y = -7/2 x - 1/2
Take the cost and multiply by the percent. (I’m going to convert the percentage into a decimal)
14,675 * 0.07 = 1,027.25
$1,027.25 is how much extra money will have to be paid for the car.
Hope this helps.
Question says that the graph of function g is a vertical stretch of the graph of function f by a factor of 3.
Now we have to find about which equation describes function g.
We know that if f(x) is the given function then a*f(x) gives vertical stretch or compress by a factor of a.
when 0<a<1 then it compresses by factor of a.
when a>1 then it stretches vertically by factor of a.
Given that function f is stretched by a factor of a so that means we use a=3 in formula a*f(x)
Hence final answer will be g(x)=3f(x).
So choice A is correct answer.
