You are adding a negative and a positive. It is like subtracting 2.1 from 3.26. Because 2.1 is negative, whenever you add it to a number, you actually subtract. To do this:
3.26 + (-2.1) is like 3.26 - 2.1
3.26 - 2.1 = 1.16
Answer:yea I think
Step-by-step explanation:
Answer:
we have
f(x)=x-6f(x)=x−6 -----> equation A
This is a linear equation with slope m=1m=1 and a y-intercept equal to -6−6
g(x)=x+6g(x)=x+6 -----> equation B
This is a linear equation with slope m=1m=1 and a y-intercept equal to 66
The function f(x) and g(x) are parallel lines
we know that
h(x)=f(x)+g(x)h(x)=f(x)+g(x)
Substitute
h(x)=x-6+x+6h(x)=x−6+x+6
h(x)=2xh(x)=2x
This is a linear equation with slope m=2m=2 that passes through the origin ( represent a direct variation)
Using a graphing tool
see the attached figure
point slope form
y-y1 = m(x-x1)
y-1 = 6(x-(-2))
y-1 = 6(x+2)
to change it into slope intercept form
distribute
y-1 = 6x+12
add 1 to each side
y = 6x+13
the y intercept is 13
Answer:
-0.34772
Step-by-step explanation:
One way of doing this problem is to change the base from 5 to 10.
Use the change of base formula:
log x
log x = ------------
5 log 5
so:
log (4/7) log 4 - log 7
log (4/7) = --------------- = ---------------------
5 log 5 log 5
Note that "log x" above is the common logarithm of x and is to the base 10.
Continuing, we get:
0.60206 - 0.84510 -0.24304
---------------------------- = --------------------- = -0.34772 (This corresponds to
0.69897 0.69897 the second given
answer choice.)
