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

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.
Which explains the error that Lila made?
Answer: I will let you do the math. A) x=brochures y=cost 1275+1.25x=y B) x=brochures r=revenue 2.50x=r C) n=net income 2.50x-(1275+1.25x)=n D) 2.50x=1275+1.25x

A giraffe's height is 5 meters 40 centimeters.
How tall is the giraffe in millimeters?
a. 0.54 mm
b. 540 mm
c. 5,040 mm
d. 5,400 mm
The height of giraffe in millimeters is 5400 millimeters. Therefore, option D is the correct answer.
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:
Cannot be counterclockwise rotation by 180 degrees anything as it would rotate the shape upside down.
Due to being the same way up but back to front, we know it points this direction -> and needs to be directly above it to be in same transition shape in the adjoining quadrant 1 which is still y axis. then we just count to check down 5 units.

What is the y-intercept of this function?
Answer:
The y-intercept would be 4
Step-by-step explanation:
If I understand this correctly, the points are: (2, 8.50),(5, 15.25), (8, 22), (12, 31)
To find this you first find the slope, which was 2.25.
Then you use a point and do the following, I used (12,31)
1. 31= 2.25(12) + b
2. 31= 27 + b
3. 31 - 27 = 27 - 27 +b
4. 4= b
a rabbit travels 3/4 miles in 7/8 of an hour. whats the rabbits unit rate?
Answer:
= 0.857143 miles per hour
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
1 hour
so the answer would be...
= 0.857143 miles per hour

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)?
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.
