Compute delta y/delta x for the interval [2,5], where y = 4x - 9.

Mathematics

Kamila [148]4 years ago

We have to compute: Δ y / Δ x.
The interval is [ 2, 5 ] and y = 4 x - 9.
y 1 = 4 · 2 - 9 = 8 - 9 = - 1
y 2 = 4 · 5 - 9 = 20 - 9 = 11
Δ y / Δ x = ( y 2 - y 1 ) / ( x 2 - x 1 ) =
= ( 11 - ( - 1 ) ) / ( 5 - 2 ) = ( 11 + 1 ) / 3 = 12 / 3 = 4
Answer:
Δ y / Δ x = 4

Use the graph to find the unit rate
Diano4ka-milaya [45]
<h3>Answer:</h3>

2.4 potatoes/pound

<h3>Explanation:</h3>

The unit rate is the slope of the line. The slope of the line is ...

... (change in y-value)/(change in x-value)

... = (36 potatoes - 12 potatoes)/(15 pounds - 5 pounds)

... = (24 potatoes)/(10 pounds)

... = 2.4 potatoes/pound

_____

The relationship here is proportional, so the line goes through the point (0, 0) and the unit rate can be figured from any point:

... (12 potates)/(5 pounds) = (24 potatoes)/(10 pounds) = (36 potatoes)/(15 pounds) = 2.4 potatoes/pound

WILL GIVE BRAINLIEST!!!!! PLS HELP ASAP!!!! 100 POINTS!!!!!!
PSYCHO15rus [73]

Answer:

the linear function gives us the points

(0,3)

(4,0)

(8,-3)

find the equation

hm

find slope

(y2-y1)/(x2-x1)

for (0,3) and (4,0)

slope=(0-3)/(4-0)=-3/4

y=-3/4x+b

given

(0,3)

y=-3/4x+3

so sub -3/4x+3 for y in other equation

(-3/4x+3)^2+x^2=4

expand

9/2x^2-9/2x+9+x^2=4

11/2x^2-9/2x+9=4

times 2 both sides

11x^2-9x+18=8

minus 8 both sides

11x^2-9x+10=0

factor

or use quadratic formula

for

ax^2+bx+c=0

x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}

2a

−b+/−

b

2

−4ac

11x^2-9x+10=0

x=\frac{-(-9)+/- \sqrt{(-9)^2-4(11)(10)} }{2(11)}

2(11)

−(−9)+/−

(−9)

2

−4(11)(10)

x=\frac{9+/- \sqrt{81-440} }{22}

22

9+/−

81−440

x=\frac{9+/- \sqrt{-359} }{22}

22

9+/−

−359

we see we have no real roots

there are no intersection points
