Find the value of f(-9).

Answers

Answer:

f(- 9) = 2

Step-by-step explanation:

f(- 9) is asking for the value of y when x = - 9

Locate x = - 9 on the x- axis

Then go vertically up to meet the graph at (- 9, 2 )

Thus when x = - 9, y = 2 , that is

"This summer, the water level of Lake Conroe changed by a rate of -1.5 feet per month. The water level at the beginning of May was 187 feet above sea level. What was the water level at the end of four months?" heelpppp asaapp

Answers

Answer:

181 feets

Step-by-step explanation:

Given that:

Rate of change in water level = - 1.5 feets per month

Water level at beginning of May = 187 feets above sea level

Water level at the end of 4 months =?

Total change after four months = rate of change per month * number of months

= - 1.5 * 4 = - 6 feets

Hence water level after 4 months :

187 feets + (-6 feets)

187 feets - 6 feets

= 181 feets

We want to solve the following system of equations using the substitution method.

Equation 1 3x-2y=-6
Equation 2 y=-5x-3

First find X by substitution of the variable Y.
step by step answer please

Answers

In the second equation you are given what Y equals, which is (-5x - 3). You would use this equation and plug it into the y value given in the first equation where it says 2y and solve

That would be

3x - 2(-5x - 3) = -6
3x + 10x + 6 = -6
3x + 10x = -6 - 6
13x = -12
X = -12/13

Then if you want to solve for Y you can use any equation and plug in the x-value found.

I’m going to use equation 2.

Y = -5x - 3
Y = -5(-12/13) - 3
Y = 4.615 - 3
Y = 1.615

(-12/13, 1.615)

Therefore the x-value is -12/13 and the y-value is 1.615.

Answer:

x = 5/4

Step-by-step explanation:

16x / 16 = 20 / 16

x = 5/4

Answer:

x = 5/4 or 1.2

Step-by-step explanation:

20/16 can be simplified to a smaller fraction, which is 5/4 because 20 and 16 have a common multiple of 4. 5/4 turned into a decimal is 1.2.

Please help: this is due in one hour. Please write let statements and equations.

Answers

Answer:

Step-by-step explanation:

let the two numbers be : x and y

x +y =131 , x-y= 35

by omitting :

x+y=135

x-y=35

cancel the ys with each other and add each side together

2x=135+35 = 170

to get x

x=170/2 =85

now u have the x time to get the y u can get it for any equation u like

85+y=135

y=135-85 = 50

the product = 85 x 50 = 4250

School fundraiser Amy sold 28 bags of popcorn and 40 candy bars and made to 282. Sarah sold 17 bags of popcorn 20 candy bars and made 160.50 the cost for a bag of popcorn in

Answers

Answer:

cost of popcorn bag is 6.5

Step-by-step explanation:

Here, we want to find the cost of a popcorn bag

let the cost of a bag of popcorn be p

let the cost of a bag of candy bar be c

Mathematically;

28p + 40c = 282

17p + 20c = 160.50

Multiply ii by 2 and subtract from i

28p + 40c = 282

34p + 40c = 321

34p-28p = 321-282

6p = 39

p = 39/6

p = 6.5

Answers

Answer:

33/36

Step-by-step explanation:

take 0.75 x 4 = 3

then take

11 x 3 = 33

total score = 36

36 - 3 = 33

so the answer is 33/36

Answer:

Samantha would score 30 points

Step-by-step explanation:

If we multiply 11 x 3 we would get 33, the 11 represents the correct awnsers and the 3 represents the points

If we multiply 0.75 and 4 we get 3, this represents the incorrect

Next I subtracted 33 and 3 to get the answer of 30.

a. x intercept
b. y intercept

Answers

X = -2
Y = -8

Hope those are the right answer

Answer:

Step-by-step explanation:

y = -4(x + 2)

y = -4x + 2 *(-4)

y = -4x - 8

a) At x intercept, y= 0

-4x - 8 = 0

-4x = 8

x = 8/-4

x = (-2)

X intercept = -2

b) y- intercept = -8
