Answer 1

Answer:

Step-by-step explanation:

we can find out by writing its equation;

9-(-3) / (14-4) = 12 / 10 = 6 / 5

so its equation gonna be y = 6/5x - 7.8

now we can grid in the answer choices:

-9 = -6/5 -7.8 so (-1 , -9) is the correct answer

Answer 2

ANSWER= a) & c)

First what you can do is find the eq of the line where you need the slope(m) and a point on the line

To find slope (m)
(Y2-y1)/(x2-x1)

(4,-3)=(x1,y1)
(14,9)=(x2,y2)

(9-(-3))/(14-4)
=(9+3)/10
=12/10
m=1.2

Sub this information into the formula
y-y1=m(x-x1)
y-(-3)=1.2(x-4)
y+3= 1.2x -4.8
y=1.2x -7.8

Now sub each point a - d into this to see if they are true

y=1.2x -7.8

a.(-1,-9)
-9=1.2(-1)-7.8
-9=-1.2-7.8
-9=-9

TRUE -POINT IS ON LINE

b.(-2,-8)
-8=1.2(-2)-7.8
-8=-2.3-7.8
-8=-10.1

NOT TRUE -POINT ISNT ON LINE

c.(29,27)
27=1.2(29)-7.8
27=34.8-7.8
27=27

TRUE -POINT IS ON LINE

d.(28,18)
18=1.2(28)-7.8
18=33.6-7.8
18=25.8

NOT TRUE -POINT ISNT ON LINE

ANSWER= a) & c)

Home heating oil is sold by the gallon. Last winter, the Romano family used 370 gallons of oil at $2.56 per gallon. If the price increases 9% next year, what will their approximate heating expense be ? Round to the nearest ten dollars .

Answers

Answer:

$1030

Step-by-step explanation:

Last winter:

Total expense = 370 * 2.56 = $947.2

Next year,

price increases 9% per gallon

which means, per gallon cost is $2.7904

Approx. expense = 370 * 2.7904 = $1032.448 which is round down to $1030

Answer: 12cm

Step-by-step explanation:

A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation
350 = 12(x + 20) to represent this situation. Solve the equation for x.
• Show your work or explain your answer.
Write your answer as a sentence that describes what the variable x represents.

Answers

Answer:

Step-by-step explanation:

350=12(x+20)

(divide both sides by 12)

29.1667=x+20

(subtract 20 from both sides)

x=9.16667

X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

Step-by-step explanation:

-3t^2+9t+54 = 0

This is the equation that needs to be solved

Divide both sides by -3

t^2 - 3t - 18 = 0

The factors of 18 are: (1 18) (2 9) (3 6)

3 - 6 = -3 and 3 x -6 = -18

So: (t + 3) (t - 6) = 0

t = -3, 6

It can't be negative so the answer is 6

Answer:

decaydecaygrowth

Step-by-step explanation:

If the base of a positive exponential is greater than 1, the function is a growth function. If it is less than 1, the function decays.

Remember that a^-1 = 1/a, so a negative exponential can be transformed to a positive one.

1. y = 2(11/5)^-x = 2(5/11)^x . . . . 5/11 < 1, so decay

2. y = e^(-2x) = (1/e^2)^x . . . . 1/e^2 < 1, so decay

3. y = 1/4e^x . . . . e > 1, so growth

the gradiant y=2x³-5x+1 at point (2,7)

Answers

Given:

The equation of the curve is:

[tex]y=2x^3-5x+1[/tex]

To find:

The gradient (slope) of the given curve at point (2,7).

Solution:

We have,

[tex]y=2x^3-5x+1[/tex]

Differentiate the given equation with respect to x.

[tex]y=2(3x^2)-5(1)+(0)[/tex]

[tex]y'=6x^2-5[/tex]

Now we need to find the value of this derivative at (2,7).

[tex]y'_{(2,7)}=6(2)^2-5[/tex]

[tex]y'_{(2,7)}=6(4)-5[/tex]

[tex]y'_{(2,7)}=24-5[/tex]

[tex]y'_{(2,7)}=19[/tex]

Therefore, the gradient (slope) of the given curve at point (2,7) is 19.
