Answer:

m = -1

Step-by-step explanation:

Find the slope of this line.

x+y=5

y= (-1)x+5

Slope (m) = -1 <-- from y = mx+b

A line parallel to the line will have the slope -1.

Given: the function defined by f(x)=3x^2-4 Which statement is true? 1. f(0) = 0 2. f(-2) = f(2) 3. f(5)+ f(2) = f(7) 4. f(5) x f

sergeinik [125]

$f(x)=3x^2-4 \\ \Downarrow \\ f(0)=3 \times 0^2-4=0-4=-4 \\ -4 \not= 0 \\ f(0) \not= 0 \\
\hbox{statement 1 is false} \\ \\
f(-2)=3 \times (-2)^2-4 =3 \times 4-4=12-4=8 \\
f(2)=3 \times 2^2-4=3 \times 4-4=12-4=8 \\ 8=8
\\ f(-2)=f(2) \\
\hbox{statement 2 is true}$

$f(5)=3 \times 5^2-4=3 \times 25-4=75-4=71 \\ f(2)=8 \\
f(7)=3 \times 7^2-4=3 \times 49-4=147-4=143 \\
71+8 \not= 143 \\
f(5)+f(2) \not= f(7) \\ \hbox{statement 3 is false} \\ \\
f(5)=71 \\ f(2)=8 \\ f(10)=3 \times 10^2-4=3 \times 100-4=300-4=296 \\
71 \times 8 \not= 296 \\
f(5) \times f(2) \not= f(10) \\
\hbox{statement 4 is false}$

Stamement 2. f(-2)=f(2) is true.

Dafna1 [17]

Answer:

Step-by-step explanation:

f(x) = 2x^2 +1

Let x =3

f(3) = 2 (3)^2 +1

= 2 *9 +1

Six times the lesser of the two consecutive even integers is 4 times the greater even integer. What are the integers?

Paladinen [302]

Answer:

Integers are 4 and 6

Step-by-step explanation:

Let the two consecutive even integers be $x,x+2$ such that $x$

Six times the lesser of the two consecutive even integers is 4 times the greater even integer.

So,

$6x=4(x+2)\\6x=4x+8\\6x-4x=8\\2x=8\\x=4$

Other integer $=x+2=4+2=6$

A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 cm and the bicycle wheel makes 3 full rotat

iragen [17]

Answer:

565.2cm

Step-by-step explanation:

Since we need to find out the circumference because the radius of the tire is 30cm. We take 30cm times 2. Which we get 60cm, then we take 60cm times 3.14 to get the circumference of 188.4cm. Then we take 188.4cm times 3 full rotations to get 565.2cm.
