All you have to do is replace every x with 2 and then solve:
<em>Make to sure to follow the Order of Operations!!</em>
-9x(2) + 11x - 7 =
(-9 × 2 × 2) + (11 × 2) - 7 =
-36 + 22 - 7 =
-14 - 7 =
-21
The answer is -21.
Hope that helps!
Answer:
A+3B=C
Step-by-step explanation:
A=Admisson Cost
3B=$3 per book
C=Total Cost
Answer:
20
Step-by-step explanation:
Formula
V = B * h
Givens
B = 200.96 square inches
V = 4019.2 cubic inches
Solution
4019.2 = 200.96 * h Divide by 200.96
4019.2/200.96 = h
h = 20 inches
Answer:
x < 22
Step-by-step explanation:
X - 8 < 14
Add x to each side
X - 8+8 < 14+8
x < 22
Let
A (-5,-4) and B (5,10)
Part 1) <span>write an equation for the line in point-slope form
</span>
we know that
the equation of a line <span>in point-slope form is
y-y1=m*(x-x1)
step 1
find the slope m
m=(y2-y1)/(x2-x1)------> m=</span>(10+4)/(5+5)----> m=14/10---> 7/5
strep 2
with m=7/5 and the point B (5,10)
find the equation of a line
y-y1=m*(x-x1)-----> y-10=(7/5)*(x-5)
the answer Part 1) is
y-10=(7/5)*(x-5)
Part 2) write an equation for the line in <span>slope-intercept form
</span>we know that
the equation of a line in slope-intercept form is
y=mx+b
step 1
find the slope m
m=(y2-y1)/(x2-x1)------> m=(10+4)/(5+5)----> m=14/10---> 7/5
step 2
with m=7/5 and the point B (5,10)
find b
y=mx+b
10=(7/5)*5+b-----> 10=7+b-------> b=3
the equation of the line is
y=(7/5)x+3
the answer Part 2) is
y=(7/5)x+3
