Find the distance between E(5,3) and F(-4,3).

Answer:

uhm sorry this is really hard maybe answer 2

Step-by-step explanation:

Answer:

(3/5, 1/5)

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define systems

3x + y = 2

4x + 3y = 3

Step 2: Rewrite systems

y = 2 - 3x

4x + 3y = 3

Step 3: Solve for x

Step 4: Solve for y

Step 5: Check

Graph the systems of equations.

Answer:

x = 3/5, y = 1/5

Step-by-step explanation:

Starting with:

3x + y = 2

4x + 3y = 3

Multiplying the first equation by -3:

-9x - 3y = -6

4x + 3y = 3

Adding the equations:

-5x = -3

Simplifying:

x = 3/5

Substituting x = 3/5 into the first equation:

9/5 + y = 2

Subtracting:

y = 1/5

Answer:

ABC is a right angled triangle

BCD is also a right angled triangle

ABD is a scalene triangle

9514 1404 393

Answer:

  ∆ABC ~ ∆BDC ~ ∆ADB

Step-by-step explanation:

The given triangle is named using the largest acute angle vertex (A) first, followed by the right angle vertex (B), then the remaining vertex (C). Using that same order, the triangles, largest-to-smallest are ...

  ∆ABC ~ ∆BDC ~ ∆ADB

Answer: AC = 7√3

tan 30° = [tex]\frac{BC}{AC}[/tex]

=> [tex]\frac{BC}{AC}=\frac{1}{\sqrt{3} }\\\\\=> AC=BC\sqrt{3} =7\sqrt{3}[/tex]

Answer:

Step-by-step explanation:

10x +5=100

-5 -5

10x=95

10 = 10

X=9.5

So x is less than 10

Answer:

Step-by-step explanation:

Because of the plus 5. You know for a fact that 10 times 10 is 100 but you need something less than 10 for the equation to be true since you're adding onto the answer to get 100

Answer:

ok

Step-by-step explanation:

Answer:

y = 2x -1

Step-by-step explanation:

when a two lines are parallel to each other that means they have the same slope.

you use point slope formula to find a line with the same slope and passes through (2,3)

y - y' = m(x - x') is the general form so you plug in (2,3) and the slope and you get

y - 3 = 2(x -2)

first your distribute the 2 into the parenthesis and you get

y-3 = 2x -4

now add 3 to both sides

y = 2x -1

Answer:

-5

Step-by-step explanation:

Each number is 5 less than the last.

Answer: pretty sure it’s B and C hope it helps ✨

Step-by-step explanation: ax2+bx+c=0 a[(x+b/2a)2-b2/4a2+c/a]=0 (x+b/2a)2=(b2-4ac)/4a2 x=[-b±√(b2-4ac)]/2a

Answer:

I would say D

Step-by-step explanation:

<GHK and <KHI are supplementary and both adds up to 180 degrees. Since it's a right angle, both of them equal 90 degrees and therefore are equal to one another

Answer:

9x8=72

Step-by-step explanation:

because it counting by nines

there fore some are different but if you multiply them you will get same answer for the  multiplication table shown of nines

example :9x7=63

1x7=7

9x1=9

9x7=63

Answer:

72 is the answer to 9x8

Step-by-step explanation:

have a good day!! :)

Answer:

x = 18

Step-by-step explanation:

The product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is

21x = 14 × 27 = 378 ( divide both sides by 21 )

x = 18

Answer:

a and c I think if I'm wrong I will try again

Answer:

The first and third option. (I think)

Step-by-step explanation:

Answer:

-3 = -v + 7

-3 - 7 = -v

3+7 = -v

-10 = -v

10 = v

Step-by-step explanation:

this is the answer i got, using basic algebra...

i hope this helps....

have a great day ahead :)

Answer:

v = 10

Step-by-step explanation:

[tex]-3=-v+7\\\\-v+7=-3\\\\-v+7-7=-3-7\\\\-v=-10\\\\\frac{-v=-10}{-1}\\\\ \boxed{v=10}[/tex]

Hope this helps.

Answer:

[tex]Number = 11\frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]Soup = 7\frac{1}{2}[/tex] quarts

[tex]Portion = \frac{2}{3}[/tex] quarts

Required

Determine the number of portions in the soup

The question illustrates division of fractions and to solve this question, we simply divide the size of the soup by the size of the given portion

[tex]Number = Soup/Portion[/tex]

Substitute values for Soup and Portion

[tex]Number = 7\frac{1}{2}\ quarts /\frac{2}{3} \ quarts[/tex]

[tex]Number = 7\frac{1}{2}/\frac{2}{3}[/tex]

Convert mixed fraction to improper fraction

[tex]Number = \frac{15}{2}/\frac{2}{3}[/tex]

[tex]Number = \frac{15}{2} * \frac{3}{2}[/tex]

[tex]Number = \frac{15*3}{2*2}[/tex]

[tex]Number = \frac{45}{4}[/tex]

[tex]Number = 11\frac{1}{4}[/tex]

Hence, there are [tex]11\frac{1}{4}[/tex]  of [tex]\frac{2}{3}[/tex] quarts in [tex]7\frac{1}{2}[/tex] quarts of soup

Answer:

∠ PRQ = 55°

Step-by-step explanation:

The angle subtended at the centre by an arc is twice the angle subtended at the circumference by the same arc, thus

∠ PQR = 0.5 × 110° = 55°

Answer:

There is 2145.52 cubic inches of air in the ball

Step-by-step explanation:

A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.

Given

Radius = r = 8 in

The volume of sphere is given by:

[tex]V = \frac{4}{3} \pi r^3[/tex]

Putting the values we get

[tex]V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3[/tex]

Hence,

There is 2145.52 cubic inches of air in the ball

Answer:

Mrs. Jones has the better deal

Step-by-step explanation:

Samantha has $300

Mrs. Jones charges $80 per lesson and she requires three so we do 80* 3 (the lessons) which equals 240  

Mrs. Beliz charges $62 per lesson and requires 4 lessons so we do 62*4 (the lessons) which equals 248

240<240 (so Mrs. Jones has the better deal, she wants less money)

Just plug in each point for the x and y and find which point is valid

Step-by-step explanation:

Answer:

(4,0)

Step-by-step explanation:

-2y= -4x + 16

y = 2x - 8

Plug 0 in for y

0 = 2x - 8

2x = 8

x = 4
