Answer:
x=11
Step-by-step explanation:
(4x)+(3x+13)=90
if you look at the beam, it includes a 90 degree angle.
7x+13=90
distributive property
7x=77
subtracted both sides by 13
x=11
divided both sides by 7 to isolate x
4(11) 3(11)+13
44 33+13
36
4(x) is the larger angle
I’m pretty sure the answer is c
56,105.61 is the answer rounded to the nearest hundred
It’s a flip of the graph on the x-axis
Therefore f(x) = - x^2 (NOT IN PARENTHESIS that would be a reflection on the y axis)
It’s a shift 4 y values down therefore
g(x) = - x^2 - 4
Answer:
a) 
b)
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
a) 
in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
This simplifies to:
b) The equation y=3x+4 follows y=mx+b. For the perpendicular line, 
. We will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
