Answer:

f(x)= 2x-5

f(-1) = 2(-1) -5

= -2 -5

= -7

g(x)= |-3x -1|

g(3)= |-3(3)-1|

=|-9 -1|

= |-10|

= 10

F(-1)- g(3)= -7-10 = -17

You start driving south for 2 miles, turn left, and drive east for another 9 miles. At the end of driving, what is your straight

yulyashka [42]

Use the Pythagorean Theorem: .

So your straight line distance is 10.

We can also recognize this as a multiple of the 3-4-5 Pythagorean triple. We have , with x being the desired value. Therefore x=10, like previously.

Parallel to y=2x-4 through (8,8)

yanalaym [24]

Answer:

y = 2x - 8

Step-by-step explanation:

Parallel lines have SIMILAR RATE OF CHANGES [SLOPES], so 2 remains the same:

8 = 2[8] + b

↑

-8 = b

y = 2x - 8 >> Parallel Equation

How do you do solve this?

solniwko [45]

The relative frequency is the frequency of the item divided by the total number of all items. The total number of all items here is: 50 + 40 + 90 +20 = 200.

$Burgers = \frac{50}{200} = 25%$
$Pasta = \frac{40}{200} = 20%$
$Pizza = \frac{90}{200} = 45%$
$Salad = \frac{20}{200} = 10%$

Hope this helps!

Find a parametrization of the line in which the planes x + y + z = -6 and y + z = -8 intersect.

rewona [7]

Answer:

L(x,y) = (2,-8,0) + (0,-1,1)*t

Step-by-step explanation:

for the planes

x + y + z = -6 and y + z = -8

the intersection can be found subtracting the equation of the planes

x + y + z - ( y + z ) = -6 - (-8)

x= 2

therefore

x=2

z=z

y= -8 - z

using z as parameter t and the point (2,-8,0) as reference point , then

x= 2

y= -8 - t

z= 0 + t

another way of writing it is

L(x,y) = (2,-8,0) + (0,-1,1)*t

HELP ASAP please i cant seem to get out of this question its hard!!!!1111!!!!1!!

zvonat [6]

I think it is A. -7

I think that because FG's distance is 6, and if FG and HI are equal, then their distances should both be equal to 6.
