Please Explain, Will give brainliest! Write an expression equivalent to x - 3y + 4?

Answer:

A

Step-by-step explanation:

Let T represent the total number of turtle nests found during the season.

The 28 turtle nests was 40% of 0.4 of the total. Therefore:

[tex]28=0.4T[/tex]

So, to find T, divide both sides by 0.4:

[tex]T=70[/tex]

So, the total number of turtle nests the group found during tthe season was 70.

Hence, our answer is A.

Answer:

$2.25

Step-by-step explanation:

Let c represent the price of cheese pizza and let p represent the prize of pepperoni pizza

3c + 2p= 11.75

2c + 1p = 7

Solve using elimination method

3c + 2p= 11.75 × 2

2c + 1p = 7 × 3

6c + 4p = 23.5

-

6c + 3p = 21

p = 2.5

Substitute 2.5 for p in equation 1

3c + 2p= 11.75

3c + 2(2.5) = 11.75

3c + 5 = 11.75

3c = 11.75-5

3c = 6.75

c= 6.75/3

c= 2.25

Hence the price of one slice of cheese pizza is $2.25

The image of (4, -7) after a reflection over the line y = x is (-7, 4) because the transformarion rule for y = x is (x, y) → (y, x)

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that:

The point is (4, -7)

The line of reflection is y = x

As the line y = x is passing through the origin.

The transformarion rule for y = x is:

(x, y) → (y, x)

(4, -7) → (-7, 4)

Thus, the image of (4, -7) after a reflection over the line y = x is (-7, 4) because the transformarion rule for y = x is (x, y) → (y, x)

Answer:

y = -2x + 17

Step-by-step explanation:

The line is parallel to 4x + 2y = 10, and parallel lines have the same slope. Let's convert this line into slope intercept form:

2y = 10 - 4x,

y = -2x + 5

So the slope of this line and our line [the line which we want to determine in slope intercept form] is -2

Given the point (7, 3) and slope -2 we can solve for the y-intercept;

y = mx + b,

3 = -2(7) + b,

-14 + b = 3,

b = 17

Your solution is y = -2x + 17 (First option)

Answer:

x is 84.

Step-by-step explanation:

this is because 84 divided by 18 equals 4.6

hope this helped :D

Answer:

if you're looking for the value of x: a number x/18=4.6 x=82.8

Step-by-step explanation:

it's a one step equation: x is being divided by 18 to get 4.6, so to get x by itself, multiply by 18 on the left side because (x/18) * 18 = x, but what you do to one side you have to do to the other, so then multiply 4.6 by 18 also to get x=82.8.

The required system of equations represents the number of adult and child tickets that Thomas sold is x + y = 210 and 5x + 2y = 610. Option A is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the number of adult tickets is x and the number of children's tickets be y,
According to the quesiton,
The tickets cost $5.00 for adults and $2.00 for children. He sold 200 tickets and collected $610.

So equaiton models as,
x + y = 210
5x + 2y = 610

Thus, the required system of equations represents the number of adult and child tickets that Thomas sold is x + y = 210 and 5x + 2y = 610. Option A is correct.

Answer:

An equation for the parabola would be y²=-19x.

Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis.  This means we will use the standard form

(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.

Beginning with the directrix:

x=h-p=4.75

h-p=4.75

Since the vertex is at (0, 0), this means h=0 and k=0:

0-p=4.75

-p=4.75

p=-4.75

Substituting this into the standard form as well as our values for h and k we have:

(y-0)²=4(-4.75)(x-0)

y²=-19x

The slope of the line is -2 or -8.5.

Options A and B are the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

From the graph,

We can have two coordinates:

(x, 0) and (0, y)

Now,

Slope.

= (y - 0)/(0 - x)

= y/-x

= - y/x

Now,

The slope is a negative value.

This means,

-2 and -8/5 can be the slope.

Thus,

The slope of the line is -2 or -8.5.
