What is the sum of the first five prime numbers?
18

26
28
39

Slope = - 3

y-int = - 1

Understanding slope intercept

y = mx + b

y = Slope(x) + y-intercept

y = -3x - 1

y = (-3)x + (-1)

Slope = - 3

y-int = - 1

Answer:

384

Step-by-step explanation:

First find 20% of 320

320 x .2 = 64

So this year, there is an increase of 64 students.

Add that to last year's 320

320 + 64 = 384

Answer:

y=-6x+48

Step-by-step explanation:

Answer:

[tex] x = \dfrac{1}{6} + \dfrac{i\sqrt{47}}{6} [/tex]   or   [tex] x = \dfrac{1}{6} - \dfrac{i\sqrt{47}}{6} [/tex]

Step-by-step explanation:

Use the quadratic formula.

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] x = \dfrac{-(-1) \pm \sqrt{(-1)^2 - 4(3)(4)}}{2(3)} [/tex]

[tex] x = \dfrac{1 \pm \sqrt{1 - 48}}{6} [/tex]

[tex] x = \dfrac{1 \pm \sqrt{-47}}{6} [/tex]

[tex] x = \dfrac{1}{6} \pm \dfrac{i\sqrt{47}}{6} [/tex]

[tex] x = \dfrac{1}{6} + \dfrac{i\sqrt{47}}{6} [/tex]   or   [tex] x = \dfrac{1}{6} - \dfrac{i\sqrt{47}}{6} [/tex]

Answer:

x=25

Step-by-step explanation:

Given

Answer:

x= -1/5

Step-by-step explanation:

1

Add 9x9x to both sides.

x+9x=-2x+9x=−2

2

Simplify  x+9xx+9x  to  10x10x.

10x=-210x=−2

3

Divide both sides by 1010.

x=-\frac{2}{10}x=−102

4

Simplify  \frac{2}{10}102  to  \frac{1}{5}51.

x=-\frac{1}{5}x=−51

[tex]y = - \frac{3}{7}x - 3 \\ [/tex]

Multiply sides by 7

[tex]7y = - 3x - 21[/tex]

Plus sides 3x

[tex]3x + 7y = 3x - 3x - 21[/tex]

[tex]3x + 7y = - 21[/tex]

Step-by-step explanation:

Answer:

22 posts

Step-by-step explanation:

on the side of 20 feet you have 5 fence posts each in including one on each of the corners. On the 35 feet side you would have 8 including the corners, but since the corner posts are done its 6 on each 35 feet side. So you get 5+5+6+6=22

Answer:

Lines 2 and 3

Step-by-step explanation:

Lines 2 and 3 are parallel lines.

Lines 1 and 3 are perpendicular lines.

The lines 1 and 2 are perpendicular lines.

Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.

Given:

The photo shows an overhead view of airport runways.

Those lines that are perpendicular to each other that means create an angle of 90° at intersecting point are perpendicular lines.

Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.

From the diagram,

Lines 2 and 3 are parallel lines.

Lines 1 and 3 are perpendicular lines.

The lines 1 and 2 are perpendicular lines.

Therefore, lines 2 and 3 are parallel lines and lines 1 and 3 and lines 1 and 2 are perpendicular lines.

Answer:

Step-by-step explanation:

Let the number of hours she worked last week be n. If Addison  worked less than 40 hours last week, this is expressed as:

n < 40 here < represents the less than sign. This means that Addison cannot work for any hour that is 40 and greater, she can only work for hours less than 40 e.g 39, 38hr etc.

The correct inequality expression is n< 40

Answer:

38 miles per hour

Step-by-step explanation:

114 miles divided by 3 hours

38 miles per hour

Step-by-step explanation:

Answer:

To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.

Answer:

The image of the point (1, -2) under a dilation of 3 is (3, -6).

Step-by-step explanation:

Correct statement is:

What are the coordinates of the image of the point (1, -2) under a dilation of 3 with the origin.

From Linear Algebra we get that dilation of a point with respect to another point is represented by:

[tex]\vec P' = \vec R + r\cdot (\vec P-\vec R)[/tex] (Eq. 1)

Where:

[tex]\vec R[/tex] - Reference point with respect to origin, dimensionless.

[tex]\vec P[/tex] - Original point with respect to origin, dimensionless.

[tex]r[/tex] - Dilation factor, dimensionless.

If we know that [tex]\vec R = (0,0)[/tex], [tex]\vec P = (1, -2)[/tex] and [tex]r = 3[/tex], then the coordinates of the image of the original point is:

[tex]\vec P' = (0,0) +3\cdot [(1,-2)-(0,0)][/tex]

[tex]\vec P' = (0,0) + 3\cdot (1,-2)[/tex]

[tex]\vec P' = (3,-6)[/tex]

The image of the point (1, -2) under a dilation of 3 is (3, -6).

Answer:

No, it is not proportional.

Step-by-step explanation:

This can be determined by looking at the first two items in the chart. I have looked at them all to find a certain pattern, but there wasn't any. The salesman earns $250 for one car sale, and he also earns $600 for two car sales, while this seems like it's just adding a $100 bonus, if you look at the third item on the chart adds a $200 bonus. You could be thinking that this is just adding a $100 bonus for how many cars were sold before, but then you move onto the fourth item on the chart. Which would give you $1,300 if the pattern was continued, yet instead the amount listed is $1,076.

Answer:

B) [tex]2n+4[/tex]

Step-by-step explanation:

The question states that Dai has 4 more cards than twice the number of cards Maura has.

"more" - add

"twice" - multiply by 2

Let n be equal to the number of cards that Maura has.

Let D be equal to the number of cards that Dai has.

When we translate this into an equation, we would get something that looks like...

[tex]D=2n+4[/tex]

Since Dai has four more cards than twice the number of cards Maura has, 2 times the number of cards Maura has plus four is equal to the number of cards Dai has. Hopefully this is easier to understand written like an equation!

Therefore, the expression would be [tex]2n+4[/tex].

I hope this helps!
