If f(x)=-2x+5, find f(4).*

Answers

Answer 1

Answer: x=-1/2y+5/2

Step-by-step explanation:

Step 1: Flip the equation.

−2x+5=y

Step 2: Add -5 to both sides.

−2x+5+−5=y+−5

−2x=y−5

Step 3: Divide both sides by -2.

−2x/-2=y-5/-2

It’ll help even more if you explain.

Answers

Answer:

angle 1 is 42

angle 2 is 138

angle 3 is also 42

Step-by-step explanation:

for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal

for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces

for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42

Which of these describes the equation –18x + 9y = –416?
A
The equation is not linear because it has 2 variables, not 1.
B
The equation is not linear because it is not in the form y = mx + b.
С
The equation is linear because it has variables with exponents of 0.
D
The equation is linear because it can be rewritten in the form y = mx + b.

Answers

Answer:

We conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the line or linear equation

[tex]y = mx+b[/tex]

where

[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept

Important Tip:

The graph of a linear equation is always a straight line.

Convert the given equation in the slope-intercept form

[tex]18x + 9y = -416[/tex]

subtract 18x from both sides

[tex]18x+9y-18x = - 18x-416[/tex]

simplify

[tex]9y = -18x - 416[/tex]

divide both sides by 9

[tex]y=-2x-\frac{416}{9}[/tex]

Now, comparing the equation [tex]y=-2x-\frac{416}{9}[/tex] with a slop-intercept form of linear equation

The slope m = -2The y-intercept b = -416/9

Therefore, we conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].

From the attached graph, is also clear that the graph of the equation [tex]y=-2x-\frac{416}{9}[/tex] is a straight line.

Hence, option D is correct.

A tank that holds up 10 gallons. when its active, a drain empties water from the tank at a constant rate, when Jada first see the tank, it contains 7 gallons of water. three minute later the tank contains five gallons of water.

At what constant/rate is the amount of water changing in the tank?

Answers

Answer:

-2/3 gallon/minute

Step-by-step explanation:

In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2).  The unit rate of decrease of the amount of water in the tank is thus:

- 2 gallons

F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?

Answers

Answer:

f(-2) = 0

Step-by-step explanation:

Given that:

f(x) = bx^2 + 32

f(2) = b(2)^2 + 32

f(2) = 4b + 32

f(2) = 4b = -32

f(2) = b = -32/4

f(2) = b = -8

Thus;

f(-2) = -8(-2)^2 + 32

f(-2) = -8(4) + 32

f(-2) = -32 + 32

f(-2) = 0

Ms.Lee bought some Reese and a bag of chips. They cost $4.36 altogether. The chips cost $1.60 more than the Reese. How much did the Reese cost?

Answers

Answer: $1.38

Step-by-step explanation:

Let the value of the Reese be represented by x

Since the chip cost $1.60 more than the Reese, then the chip will be:

= x + 1.60

Since they cost $4.36 altogether, the value of the Reese will be:

x + (x + 1.60) = 4.36

2x + 1.60 = 4.36

2x = 4.36 - 1.60

2x = 2.76

x = 2.76/2

x = 1.38

The Reese cost $1.38

what is 512.3 divided by 10

Answers

Answer:

51.23

Step-by-step explanation:

Hi !

So basically all you need to do with an equation like this move the decimal.

And the direction you move it depends on the value of the largest digit as well as if it is larger or smaller than 0.

So lets look at 10 and make it 10.0 so its a decimal and make things a bit easier.

So 10.0 is just one digit moved in the decimal world. (100.0 would be 2, 1000.0 would be 3, and so on.)

And 10.0 is greater than 0.

Greater than 0 = Move decimal left

Less than 0 = Move decimal right

So now we know to move one space to the left.

512.3

>

One to the left

>

51.23

And its that easy, that is your answer.

I hope this helps!
