A line passes through the point (-4,9) and has a slope of
-3/2
Write an equation in point-slope form for this line.

Answers

Answer: y - 9 = (-3/2) (x - (-4))

Step-by-step explanation:

We can use the formula y-y1 = m(x-x1)

Where (x1,y1) are (-4, 9) and m = -3/2. Plug in the values and we get

y - 9 = (-3/2) (x - (-4))

!!HELP: 20 POINTS!!At the end of a snow storm, Jace saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. The depth of snow on Jace's lawn, in inches, can be modeled by the equation S=15-1.5t,where t is the time, in hours, after the snow stopped falling. What is the y-intercept of the equation and what is its interpretation in the context of the problem?

Answers

Answer:

the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.

The rate of melting is 1.5inches per hour.  It will take 10 hours at the melting rate given of 1.5 to melt all the snow.

Step-by-step explanation:

the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.

The rate of melting is 1.5inches per hour.

At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start

At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.

The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C. What was the final temperature on Sunday?

Answers

Given :

The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C.

To Find :

The final temperature on Sunday.

Solution :

Temperature on Saturday = initial temperature + 4⁰C

= 32⁰C + 4⁰C

= 36⁰C.

Temperature on Sunday = temperature on Saturday - 7⁰C

= 36⁰C - 7⁰C

= 29⁰C

Therefore, final temperature on Sunday is 29⁰C.

Hence, this is the required solution.

Subtract 5x^2+8x-11 from 3x^2+8x-7

Answers

Answer: -2x^2+4

Explanation: First you’d need to rewrite the equation as (3x^2+8x-7)-(5x^2+8x-11). Then since you are subtracting, distribute the negative to the right side which will then give you -5x^2-8x+11 since you flip the signs. Then simply combined like terms. -5x^2 + 3x^2 is -2x^2. Then 8x-8x is 0 and lastly, +11-7 is 4. So in order, all together, your answer is -2x^2+4.

Which function has a greater rate of change?
Function A:
x 1.5 2.5 3.5 4.5 5.5
y –5 0 5 10 15
Function B:
y = –4.5x + 15
Function A has a rate change of BLANK and Function B has a rate change of BLANK so Function BLANK has a greater rate of change

Answers

Answer:

5; -4.5; Function A

Step-by-step explanation:

Rate of change for function A is:

(15 - 10)/(5.5 - 4.5) = 5/1 = 5

Rate of change of function B is:

-4.5 as the slope is the rate of change

Comparing the values:

5 > - 4.5

Function A has a greater rate of change

Answer:

Answer:

5; -4.5; Function A

Step-by-step explanation:

Rate of change for function A is:

(15 - 10)/(5.5 - 4.5) = 5/1 = 5

Rate of change of function B is:

-4.5 as the slope is the rate of change

Comparing the values:

5 > - 4.5

Function A has a greater rate of change

Two friends, Caleb and Ynez are both selling brownies for a class
fundraiser. They decide to advertise how much buying a certain number of
brownies will cost in two different ways. Create an equation for the cost, c,
of n-brownies for Caleb's pricing.

Answers

Answer:

B. 1.25n = c

Step-by-step explanation:

Take one of the points. 20 and $16.

It will look like this 20/16n = c

20/16 = 1.25

1.25n = c

Hope this helps ya! Keep smiling!

The required equation is 1.25n = c where the cost is c and n-brownies for Caleb's pricing. which is the correct answer would be an option (B).

Y=2x and 5x-y=9 substitution

Answers

Answer:

3,6

Step-by-step explanation:

Plug 2x(y) into 5x -y = 9

5x -2x = 9

Add like terms.

3x = 9

Divide both sides by 3.

x = 3

Now, in order to find y, plug 3(x) into y = 2x

y = 2(3)

y = 6

The solution of system of equation is x=3 and y=6.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y=2x .....................(1)

5x-y=9...............(2)

Now substitute the value of y in equation (2), we get

5x - 2x = 9

3x = 9

Divide both side by 3.

x= 3

and, y= 2x = 6

PLEASE HELLPPPP The town of Madisonville, Texas was hit by a strong storm in late July. Most of the city lost power for several hours, and damage was severe in parts of the city. The Lakeside Cafe, famous for its misspelled sign saying, Chicken-Fried Stake, lost its roof in the storm. Amazingly, no employees or customers were injured. John Paxton, who was eating in the restaurant at the time, said, They told us there was no way to know if it was a tornado or not. Well, Ive never seen this kind of damage from anything but a tornado. Fallen limbs and downed power lines were also common problems across the city, blocking passage down dozens of streets. Crews worked for days without pause to restore power and to cut and haul away large limbs. With many businesses closed until power could be restored, hundreds of local residents found themselves stuck at home without electricity and therefore without air conditioning. Local woman Sally H. was sitting on her front porch, fanning herself with a shoe catalog. Its hot, she said. Normally, I would enjoy a day off of work, but this isnt a normal day off. The hospital was able to stay open and powered by electricity generators. Furman Simms, working the front desk, said it seemed almost like a normal day. We saw more people today than usual, he explained, but it wasnt bad. We never ran out of beds. I expected it to be a lot busier.The reader can infer that hundreds of Madisonville residents were probably A. glad they had generators. B. helped haul away tree limbs. C. enjoyed not going to work.
