Given f(x)=-5x+1, solve for x when f(x)=-4.

Answers

Answer:  1

======================================================

Explanation:

We're told that f(x) = -4. That means we can replace the f(x) in the first equation and solve for x.

f(x) = -5x+1

-4 = -5x+1 ..... replaced f(x) with -4

-5x+1 = -4

-5x = -4-1

-5x = -5

x = -5/(-5)

x = 1

As a way to check, we plug in x = 1 to get...

f(x) = -5x+1

f(1) = -5(1)+1

f(1) = -5+1

f(1) = -4

So the answer is confirmed. If f(x) = -4, then x = 1.

f(x) = -5x+1

1. Substitute
f(x) = -5(-4) + 1

2. Expand and Simplify
-5 x -4 = 20
20+1 = 21

f(x)= 21 when f(x)= -4.

I need help please

Answers

Answer:

-6.809 > -6.812|

-6.809| < -6.812|

Step-by-step explanation:

Answer:

-6.809 > -6.812 and |-6.809| < |-6.812|

Step-by-step explanation:

-6.809 is greater than -6.812 because the number is more closer to zero.

A negative number more closer to zero is greater than a negative number that is farther away from zero.

Also, |6.809| <| -6.812| Because the absolute value for both numbers is 6.809 and 6.812 meaning the number 6.812 is greater than the number 6.809.

Step-by-step explanation:

The sides go from 4 units to 1 unit so the dilation must be 1/4

Answer:

1 over 4

Step-by-step explanation:

Step 1. The shape dilates smaller than itself so will always be less than 1

Step 2. We count P to 0 in the larger shape and see = 4 unit

and compare to P' to 0' in the smaller shape and see = 1 unit

Answer. The dilation is 1/4

need help on slope pt 2. explain it pls

Answers

Answer:

Slope = -3/2 y-intercept = (0,1)

Step-by-step explanation:

The slope is rise/run.

We can take the points (-2,4) and (0,1) to find the slope.

In the same amount of time x increases by 2, y decreases by 3. This gives us the slope of -3/2.

The y-intercept is the y level that the slope passes through when x = 0

On this line, that is the point (0,1)

Reminder that points are (x,y)

Slope=-3/2; y-intercept (0,1)

The line crosses the y axis at the point one making that they answer for the y-intercept.

The slope is -3/2 because it went down 3, making it negative, and over two.

What is Metric System?

Everything around us has a measurement value, from the amount of sugar you put in a cake to the size of a football field. Each thing is measured differently based on its length, weight, volume, or duration. With these measurements, the idea of "Metric System" is introduced.

Given that, a giraffe's height is 5 meters 40 centimeters.

Metric conversion refers to the conversion of the given units to desired units for any quantity to be measured.

We know that 1 meter = 1000 millimeters and 1 centimeter = 10 millimeters

Here, 5 meters = 5000 millimeters and 40 centimeters = 400 millimeters

So, the height is 5000+400

= 5400 millimeters

Therefore, option D is the correct answer.

Step-by-step explanation:

This the fractions 3/4 miles and 7/8 hours are equal to

0.75 miles and 0.875 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 0.875

0.75 miles ÷ 0.875

0.875 hours ÷ 0.875

=

0.857143 miles

Fatoumata is ordering a taxi from an online taxi service. She has to pay a flat charge just to order the taxi, and then has to pay per mile, depending on how far she travels, as is represented in the linear graph below. What is the meaning of the point (1,7)?

Answers

Answer:

The first option is correct.

Step-by-step explanation:

We can see that when she travels 0 miles, she payed $4.50.

So $4.50 is the flat fee for ordering a taxi.

Point (1,7) means that after traveling 1 mile, she has to pay a total of $7.

The first option is correct.

We can also find out the amount of money per mile.

We know that the flat fee is 4.50, and the total fee for 1 mile is 7, so we can subtract 4.5 from 7

7 - 4.5 = 2.5

That means Fatoumata pays $2.5 per mile.

Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total cost. The total cost for 35 brochures is $41.45. The total cost for 65 brochures is $55.55.

Step 1: Write the ordered pairs (35, 41.45) and (65, 55.55).

Step 2: Find the slope. m = StartFraction 55.55 minus 41.45 Over 65 minus 35 EndFraction = 0.47

Step 3: Find the y-intercept to write the equation in slope intercept form. y minus 55.55 = 0.47 (x minus 35). Y minus 55.55 = 0.47 x minus 16.45. y = 0.47 x + 39.1.
