If f(x)=3x+1 then f(a+h)-f(a)

1 answer:

7 0

F(x) = 3x+1
put x = a+h
f(a+h) = 3(a+h) + 1
f(a+h) = 3a + 3h + 1
put x = a
f(a) = 3a + 1
f(a+h)-f(a) = 3a + 3h + 1 -(3a+1)
f(a+h)-f(a) = 3a +3h + 1 - 3a -1
f(a+h)-f(a) = 3h

Find the equation of the line passing<br> through the points (2, 4) and (3, 2).<br> y = [? ]x + [ ]

PtichkaEL [24]

Answer:

first find slope m

m=(4-2)/(2-3)

m= -2

so equation line is

y-y1=m(x-x1)

y-4=-2(x-2)

y-4=-2x+4

y=-2x+4+4

y=-2x+8

?=-2

What is (3×10) ×8= ------ × (10×8) elementary 5th grade

Tamiku [17]

This is an example of the commutative property of multiplication.

That property states: $(a \times b) \times c = a \times (b \times c)$

So using that property, we can figure out that 3 should be in the blank.

How do I solve this??

tresset_1 [31]

Answer:

x = 7.5

Step-by-step explanation:

Since DF bisects ∠CDE then

∠EDF = ∠CDF, hence

8x = 4x + 30 ( subtract 4x from both sides )

4x = 30 ( divide both sides by 4 )

x = 7.5

A town has accumulated 22 inches of snow, and the snow depth is increasing by 66 inches every hour. A nearby town has accumulat

Aleks [24]

Create an expression. Solve for x

22+66x=66+33x
Subtract 33x from both sides
22+33x=66
Subtract 22 from both sides
33x=44
Divide both sides by 33
x=44/33=4/3 or 1.3 hours
