Help me with my homework please

Answer:

this was to on my test let me give you one picture read it.hope it helps

Given:

The point is (-5,7).

To find:

The image of the given point after 90 degrees counter clockwise rotation.

Solution:

If a point rotated 90 degrees counter clockwise, then

[tex](x,y)\to (-y,x)[/tex]

Let the given point is P(-5,7). Using the above rule, we get

[tex]P(-5,7)\to P'(-7,-5)[/tex]

Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).

Answer:

Step-by-step explanation:

First calculate the total number of students in all the schools:

= 618 + 378 + 204  

= 1,200 students

Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.

North Middle school:  

= 618/1,200 * 20  

= 10 students

Central Middle School:  

= 378 / 1,200 * 20  

= 6 students

South Middle School:  

= 204/1,200 * 20  

= 4 students  

[tex]5(2x-4)=10x-20[/tex]

Hope this helps.

Step-by-step explanation:

Write 5

(2

x−

4)

as an equation.y

=

5

(2x−4)

Step-by-step explanation:

y=5x+12 ....... eqn 1

3y+4X=150.....eqn 2

sub eqn 1 into 2

3(5x+12) + 4X = 150

15X+36 +4X=150

19X = 150-36

19X= 114

X= 6

Answer:

$25.76

Step-by-step explanation:

$1.12×23ft=$25.76

Given:

Two trail maps:

Trail on the first map = 8 cm

Trail on the second map = 6 cm

Scale on first map = 1 cm : 2 km

A) What is the scale factor from the map to the actual trail?

For the first map, the scale factor is 1 cm: 2km. Therefore the actual trail is 8 centimeters * 2 kilometers = 16 km.

The scale factor of the second map is 16 km / 6 cm = 2.67 km : 1 cm

B) The length of the actual trail is 16 kilometers.

Answer:

7 million

Step-by-step explanation:

If you use your finger and continue the graph you will get to 7.\.

Answer:

7 million

Step-by-step explanation:

Take 2 points of the graph

(3,3) and (6,4)

the numbers on the x axis are 3 and 6

the numbers on the y axis are 3 and 4

Everytime the x axis goes up by 3, the y axis goes up by 1

Therefore, the slope is [tex]\frac{1}{3}[/tex]

If you continue the slope, you would get (12,6) and then (15,7)

Answer:

x-10

Step-by-step explanation:

you have to do what is in the parenthesis first. Do distributive property to

-(x-8)

-(x)-(-8)= -x+8

now you have 5-(3-x+8)

Do distributive property again

5-3+x-8

x-8+2

x-10

Answer:

My answer:(K-6) (K+4)

Step-by-step explanation:Note:If this is wrong my apologies.Sorry if this doesn't help.

All i did to solve this math problem is that i factor k^2-2k-24 by using the AC method.

The factors of the quadratic equation by applying the factorization method are (k + 4) and (k - 6)

Used the concept of the quadratic equation which states that,

An algebraic equation with the second degree of the variable is called a Quadratic equation.

Given that,

The quadratic equation,

k² - 2k - 24

Now, apply the factorization method in the above equation,

k² - 2k - 24

k² - (6 - 4)k - 24

k² - 6k + 4k - 24

k (k - 6) + 4 (k - 6)

Therefore, the factors are,

(k + 4) (k - 6)

#SPJ6

Answer:

9 days

Step-by-step explanation:

100 + 50= 150

100 scouts= 12 days

×2 ÷2

200 scouts= 6 days

Midpoint of 100 scouts and 200 scouts= 150

Midpoint of 12 days and 6 days= 9 days

Step-by-step explanation:

Answer:

x < 7

Step-by-step explanation:

-8x + 40 > -16

-8x > -16 - 40

x < -56/-8

x < 7

(when changing sides of neg. multipliers, you need to change the sign side, dont fall for that common mistake)

Answer:

x < 7

Step-by-step explanation:

-8x + 40 > -16 (subtract 40 on both sides)

-8x > -56 (divide by -8) - be careful and don't forget to flip the sign when dividing by a negative number

x < 7 (final answer)

Answer:

3/8

Step-by-step explanation:

3 numbers which fit the description: even and greater than 2 (4,6,8).

Answer:

B

Step-by-step explanation:

Answer: In order to find what the coordinates of B are is by trying to know how we got to (-2,0) of line AB. You have to subtract 3 from A coordinate x which is 1,it will give you -2, and you have to subtract 1 from A coordinate y which is 1,it will give you 0.

Answer:

A. In order for DeMarco to know if the value is a solution of the equation, he will need to multiply both sides by 2 which will make the equation 2×(1/2x)=(2)×*4)

B. Yes, x=8

Answer:

x = 14

BE = 6

Step-by-step explanation:

to find 'x':  BG = 1/2[(x-9) + (3x-13)]

BG = 4x-22 / 2

BG = 3x-25

3x-25 / 1 = 4x-22 / 2

cross-multiply:

4x-22 = 2(3x-25)

4x-22 = 6x-50

-2x = -28

x = 14

to find 'BE':  CB = BE

2x+4 = 7x-1

-5x = -5

x = 1

BE = 7(1) - 1

BE = 6

Answer:

x < 3

Step-by-step explanation:

Isolate the variable, x. Treat the < sign as an equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, add 1 to both sides of the equation:

4x - 1 (+1) < 11 (+1)

4x < 11 + 1

4x < 12

Next, divide 4 from both sides of the equation:

(4x)/4 < (12)/4

x < 12/4

x < 3

x < 3 is your answer.
