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)

A number x divided by 18 is equal to 4.6

Answers

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.

What does it mean to get 150% salary raise? Explain in words and then give an example showing calculation.

Answers

To get a 150% salary raise, you’re increasing the amount of money in your raise. For example, if your salary is 15,000 you would set up an inequality part/whole = %/100 So in this situation x is what we’re trying to find. X/15,000=150/100 which is 22,500 which we add to the salary. 15,000+22,500=37,500

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

Options A and B are the correct answer.

What is an equation of a line?

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.

A group of biologists found a total of 28 loggerhead turtle nests along a beach during a certain season. This was 40% of the total number of turtle nests the group found during that season. What was the total number of turtle nests the group found during that season?

70
85
110
143

Answers

110 I believe is the answer

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:

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
