Leo took an Uber to get to football practice. Uber charged $1.25 per mile (m) and he gave the driver a $5.00 tip. If the total trip was $16.25, how many miles did he travel to football practice?

Answers

Answer:

9miles

Step-by-step explanation:

Step one:

given data

we are told that the uber charges $1.25 per mile

and that Leo also gave a tip of $5

the function for the total charge is given as

y=mx+c

Step two:

we will use the notation m for the number of miles traveled

given that the total trip is $16.25

16.25=1.25m+5

solving for m we have

16.25-5=1.25m

11.25=1.25m

divide both sides by 1.25

m=11.25/1.25

m=9

So he travelled 9miles

6x+8=3x-19

A. x = 3
B. x = -3
C. x = -9
D. x = -11/3

Correct answer will get brainiest!

Answers

Answer:

C

Step-by-step explanation:

Given

6x + 8 = 3x - 19 ( subtract 3x from both sides )

3x + 8 = - 19 ( subtract 8 from both sides )

3x = - 27 ( divide both sides by 3 )

x = - 9 → C

Answers

Answer:

What is quadrilateral?

A quadrilateral is a shape with four sides, four vertices, and four angles that is only two dimensional. Convex and concave are the two main forms. Convex quadrilaterals can also be divided into a number of subgroups, including trapezoids, parallelograms, rectangles, rhombus, and squares.

Given that,

Quadrilateral ABCD is reflected over a line y

Hence preimage = ABCD and image = TURS

After reflection,

The new position of A = T

New position of B =U

New position of C = R and

New position of D = S

By transformation properties,

For reflection the scale factor is 1 and hence AB will have the same length as TU

Since,

AB = 7 inches,

Therefore,

TU = 7 inches.

Step-by-step explanation:

AC = 4 + 6 = 10 cm

[tex]\frac{10}{6}[/tex] = [tex]\frac{x+5}{x}[/tex] ⇔ 10x = 6(x + 5) ⇒ x = 7.5 cm

A) y = 3x + 2
B y = 3x - 2
C y-1/3x+2
D y=1/3x-2

Answers

B, y=3x-2. It’s a positive line, so it can’t be C. The line intersects the y axis at -2 so we know it’s either B or D. If you count the points the line runs through, you can see it rises 3 points and only runs 1. That means the slope is 3/1 which equals 3. B’s slope is 3, so you have your answer!

Use the diagram to find the measure of angle KHL.

Answers

Answer:

m∠KHL = 43°

Step-by-step explanation:

From the picture attached,

m∠KHL ≅ m∠GHL [Given in the picture]

Now substituting the values of the angles,

(3x + 1) = (5x - 27)

1 + 27 = 5x - 3x

28 = 2x

14 = x

m∠KHL = (3x + 1)° = (3 × 14) + 1

                             = 42 + 1

                             = 43°

Therefore, measure of ∠KHL = 43°

how do you find an equation for a line with a slope of 2/3 passing through (1,-4)​

Answers

Answer:

The standard general equation for a straight line is:

y = mx + C. You said the slope of line is 2/3. m is always the slope in this context. So with the numerical value slope we have the line

Y = 2/3 X + C. You also said the line passes through the point (1, -4) that is the X value is 1 and the y value is -4. Substitute these value into the linear equation to find C, as follows

-4 = 2/3 + c. and so C = - 4 - 2/3 = -14/3 and so the equation of line is :

y = 2x/3 + 14/3 or if you like 3y = 2x + 14

It is important to remember that the convention of the bracketted numbers e.g. (1,-4) or ( 1, -4, z), say is that the first number in the brackets indicates the X value, the second the y value and the third, the z value in the case of 3 D coordinates.

(2) If da Vinci did have exotropia, in which an eye turns outward, he would not have been the only artist in history with that condition.(3) Christopher Tyler, a visual neuroscientist at City University of London, noticed a pattern in da Vincis portraits and in works depicting the great artist. (4) While few self-portraits of da Vinci exist, Tyler argues that many of da Vincis portraits reflect his appearance. (5) As the great artist himself said, the soul guides the painters arm and makes him reproduce himself, since it appears to the soul that this is the best way to represent a human being.(6) To test his theory that da Vinci had exotropia, Tyler studied the eye alignments of the subjects of six pieces of art that purportedly depict the Renaissance artist himself, including da Vincis Vitruvian Man and Salvator Mundi and Andrea del Verrocchios sculpture David. (7) The results confirmed Tylers suspicions: da Vinci likely had exotropia, with one eye turning out at -10.3 degrees.(8) Tylers findings, which he published in JAMA Ophthalmology, created a stir in both the art and science communities. (9) Only about 1 percent of the population has exotropia, yet previous studies have suggested that other famous artistslike Rembrandt, Picasso, and Degashad it as well, which indicates that the eye condition was more common in centuries past than it is now. (10) Tyler believes that da Vincis condition was intermittentthat is, his eye drifted out of alignment when he was relaxed, but when he focused, it would realign. (11) If Tyler is right and da Vinci could control his exotropia, then the artist could switch from 2-D to 3-D vision, enhancing his ability to accurately capture three-dimensional figures on a two-dimensional canvas.The writer is working on a revision of the passage and has written the following thesis statement for it.Based on the evidence from Tylers studies, it is clear that this condition was the primary reason for da Vincis success.Which of the following is most likely the main claim that the writer is planning to make in the new version of the passage?The only way for an artist to be successful is to have exotropia.ADa Vinci was more successful as an artist than others who also had exotropia.BStudying just a few works of art can provide compelling information about an artists physical conditions.CThe only way to fully understand an artists work is to study the artists physical conditions.DDa Vinci was a great artist because he had exotropia.EIs it E?
