Answer:
A is the answer
Step-by-step explanation:
(0, -5):
-5 = 2(0) - 5 >>> -5 = -5
-5 = (0)^2 - 5 >>> -5 = -5
(2, -1):
-1 = 2(2) - 5 >>> -1 = 4 - 5 >>> -1 = -1
-1 = (2)^2 - 5 >>> -1 = 4 - 5 >>> -1 = -1
So first we have to find out what the bottom number is so
8x+14
subsitute 8 for x
8(8)+14
64+14
78
so 156/78
an easy way to do this is to factor it out and find the 'ones' like 4/8=1/2 times 4/4 (4/4=1 and can be canceled out)
*=times
156=2*2*3*13
78=2*3*13
so (2*2*3*13)/(2*3*13)
2/1 times (2*3*13)/(2*3*13)
we can cross out the (2*3*13) and get
2 as the answer
Answer:
The equation of the line tangent to the graph of f at x = -1 is 
.
Step-by-step explanation:
From Analytical Geometry we know that the tangent line is a first order polynomial, whose form is defined by:
(1)
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- Intercept, dimensionless.
The slope of the tangent line at 
is:
(2)
If we know that 
, and 
, then the intercept of the equation of the line is:
The equation of the line tangent to the graph of f at x = -1 is .
Prove
m∠5+m∠2+m∠6=180°
we have that
m∠1+m∠2+m∠3=180° equation I
m∠1=m∠5 -------- > in<span>ternal alternate angles equation 2
</span>
and
m∠6=m∠3-------- > internal alternate angles equation 3
<span>I substitute equation 2 and equation 3 in equation I</span>
m∠1+m∠2+m∠3=180°-------- > m∠5+m∠2+m∠6=180°------- > is ok
