Please help do these questions I GIVE BRAINLIEST!! 40 POINTS

Answer:DE = 4

AB = 30

Step-by-step explanation:

Answer:

30cm²

Step-by-step explanation:

AE/BD = CE/CD

9/6 = CE/8

CE = 9/6 x 8

CE = 12cm

DE = CE - CD

DE = 12 - 8 = 4 cm

½(6 + 9)4 = 30cm²

Answer: 6 cm is 45 km

5 cm is 7.5 km

Answer:

  a.  40

  b.  0

  c.  50

Step-by-step explanation:

a) 46 + (-2k) for k = 3 is ...

  46 + (-2(3)) = 46 -6 = 40

__

b) 46 + (-2k) for k = 23 is ...

  46 + (-2(23)) = 46 -46 = 0

__

c) 46 + (-2k) for k = -2 is ...

  46 + (-2(-2)) = 46 +4 = 50

Answer:

  2

Step-by-step explanation:

The question is asking the value of f(5). Put 5 where x is and do the arithmetic.

  [tex]f(x)=\dfrac{5x-15}{5}=x-3 \qquad\text{simplified}\\\\f(5)=5-3=\boxed{2}[/tex]

The range value of interest is 2.

Answer:

X(6, 1), Y(-4, 0), Z(-1, 3)

Step-by-step explanation:

When reflecting an image across the y-axis, (i.e, across a vertical line at the position x = 0), All you need to do is negate the x coordinate of each point, so:

(-6, 1) becomes (6, 1)

(4, 0) becomes (-4, 0)

(1, 3) becomes (-1, 3)

Answer:

(6,1) (-4,0) (-1,3)

Answer:

i believe the fist one is a and second is b

Step-by-step explanation:

lol hope it helped u

Answer:

the second number

Step-by-step explanation:

EX:  ( -3, 2 ) the 2 would lie on the y axis because its the second number the x axis always comes 1st and the y axis 2nd

Answer:

x=80 and y=30

Step-by-step explanation:

HOPE THAT HELPS!!!!!!!

Answer:

You would move each point on y=P(x) up by three. Or add 3 to each y coordinate

Step-by-step explanation:

This is because we're not manipulating the value of x before it gets multiplied by P.

For example:

If x is set to equal 5 and P equal to 2, then the parent function would have a coordinate of (5,10) since 2(5)=10 but the new function would have a coordinate of (5,13) since 2(5)+3= 13 due to order of operations (2×5 =10, then we add 3).

Answer:

Step-by-step explanation:

Step 1:

Plot y=P(x) from x=-a to x=a with x=0 as the middle point of the distance between a and -a.

Step 2:

Add the value of +3 to each point of y=P(x), ie, y=P(x)+3 meaning that the graph y=P(x) will be pulled up three units on the y axis.

Answer:

1/9

Step-by-step explanation:

6 feet = 6*12 = 72

Scale factor = 8/ 72 = 1/9

Answer:

1/9

Step-by-step explanation:

6ft = 72 inches

8/72 = 1/9

1) 12/1

2) 517/100

3) 2/25

4) 67/800

5) 5/2

Answer:

y=4x

Step-by-step explanation:

a proportional relationship has to cross through the origin and all of the other answers have y intercepts and if it has a y intercept then it will not pass through the origin.

Answer: a) [tex]\dfrac{13}{7}[/tex]

Step-by-step explanation:

Median: Line segment from one vertex of a  triangle to the midpoint of the opposite side. i.e. it bisects the opposite side.

Centriod: Point of intersection of a triangle of its medians

.Also, it is [tex]\dfrac23[/tex] of the distance from vertex to the midpoint of opposite side.

Given:  CD is a median in triangle ABC and M is centriod.

[tex]\Rightarrow CM=\dfrac23 CD[/tex]

Since CM = x +5 and CD = 5x + 1

[tex]\Rightarrow\ x+5=\dfrac{2}{3}(5x+1)\\\\\Rightarrow\ 3(x+5)=2(5x+1)\\\\\Rightarrow\ 3x+15=10x+2\\\\\Rightarrow\ 10x-3x=15-2\\\\\Rightarrow\ 7x=13\\\\\Rightarrow\ x=\dfrac{13}{7}[/tex]

Answer:

4

Step-by-step explanation:

Slope is rise over run, but you can also find the slope between two points with this formula:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

12-4=8

----------

6-2=4

8/2=4

Answer:

Step-by-step explanation:

[tex] \frac{6}{x - 1} = \frac{4}{x + 2} [/tex]

[tex]6x + 12 = 4x - 4[/tex]

[tex]6x - 4x = - 12 - 4[/tex]

[tex]2x = - 16[/tex]

[tex]x = - 8[/tex]

Answer:

n=-3.1

Step-by-step explanation:

To solve this, first subtract 3 from both sides of the equation to get 2n=-6.2. Next, divide both sides of the equation by 2 n order to get the final answer of n=-3.1

Answer:

A. $23.34

Step-by-step explanation:

The computation of the amount of money spend altogether is given below:

= Purchase price of 4 binder + pack of pencils + new coat

= $2.14 + $1.25 + $19.94

= $23.34

We simply added the above three cost so that the total money incurred would be come

Hence, the correct option is A
