Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. y= (3x+4)(- 5x - 6)

Mathematics

Answer:

x1= -4/3 x2= -6/5

Step-by-step explanation:

y= (3x+4)(-5x-6)

now first we replace y with a zero 0

0=(3x+4)(-5x-6)

now we put the 0 to the right

(3x+4)(-5x-6)=0

when the product of factors 0, at least one of the factors is 0 so we do this:

3x+4=0

-5x-6=0

now we solve 3x+4=0 and it leads to:

x=-4/3

after that we do the same for -5x-6=0:

x2=-6/5

sorry if you dont understand it too good, im not really good at explaining, and its also my first time answering in this app, but i hope you understand and it solves your problem!

Given functions f(x)=3x^2, g(x)= x^2-4x+5, and h(x)=-2x^2+4x+1<br> Rank them from least to greatest
Sindrei [870]
Ok, ranked by axis of symmetry

basically x=something is the axis of symmetry
the way to find the axis of symmetry is to convert to vertex form and find h and that's the axis of symmetry

but there's an easier way

for f(x)=ax^2+bx+c
the axis of symmetry is x=-b/2a
nice hack my teacher taught me


so

f(x)=3x^2+0x+0
axis of symmetry is -0/(3*2), so x=0 is the axis of symmetry for f(x)

g(x)=1x^2-4x+5,
axis of symmetry is -(-4)/(2*1)=4/2=2, x=2 is axis of symmetry for g(x)


h(x)=-2x^2+4x+1
axis of symmetry is -4/(2*-2)=-4/-4=1, x=1 is the axis of symmetry for h(x)


0<1<2
axisies
f(x)<h(x)<g(x)

order based on their axises of symmetry is f(x), h(x), g(x)

A car is moving 70 miles per hour. how far does it travel in 16 seconds
Serjik [45]

Answer:

0.311 miles

Step-by-step explanation:

Convert 16 seconds to hours :

16 /60×60

= 16÷3600

= .004444hrs

Distance = Speed × time

= 70 × 0.00444444

= 0.311 miles
