Answer:

e = -2

Step-by-step explanation:

9e - 7 = 7e -11

9e - 7e - 7 = -11

9e - 7e = -11 + 7

2e = -4

e = -2

Answer:

e = -2

Step-by-step explanation:

9e - 7 = 7e - 11

Subtract 7e from both side

2e - 7 = -11

Add 7 to both sides

2e = -4

Divide by 2 to isolate e

e = - 2

MATH QUESTION!! WILL MARK BRAINLIEST!! PAST DUE HELP ASAP!!!

Answer:

Proof below

Step-by-step explanation:

Right Triangles

In any right triangle, i.e., where one of its internal angles is 90°, some interesting relations stand. One of the most-used is Pythagora's Theorem.

In a right triangle with shorter sides a and b, and longest side c, called the hypotenuse, the following equation is satisfied:

$c^2=a^2+b^2$

The image provided in the question shows a line passing through points A(0,4) and B(3,0) that forms a right triangle with both axes.

The origin is marked as C(0,0) and the point M is the midpoint of the segment AB. We have to prove.

$CM=\frac{1}{2}AB$

First, find the coordinates of the midpoint M(xm,ym):

$\displaystyle x_m=\frac{0+3}{2}=1.5$

$\displaystyle y_m=\frac{4+0}{2}=2$

Thus, the midpoint is M( 1.5 , 2 )

Calculate the distance CM:

$CM=\sqrt{(1.5-0)^2+(2-0)^2}$

$CM=\sqrt{2.25+4}=\sqrt{6.25}=2.5$

CM=2.5

Now find the distance AB:

$AB=\sqrt{(3-0)^2+(4-0)^2}=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}$

AB=5

AB/2=2.5

It's proven CM is half of AB

Answer: Area = x² + 6x + 8

Step-by-step explanation:

Area = length x width

Area = (x+2)(x+4)

Area = (x)(x) + (x)(4) + (2)(x) + (2)(4)

Area = x² + 4x + 2x + 8

Area = x² + 6x + 8

Solve a = b - 4/ c for b.

ahrayia [7]

Answer:

ac + 4 = b

Step-by-step explanation:

Step 1: Write equation

a = (b - 4)/c

Step 2: Multiply both sides by c

ac = b - 4

Step 3: Add 4 on both sides

ac + 4 = b

tapes-r-us is have a sale on hq tape players. The regular price is $60. The discount is $18. What percent discount is this?

olga nikolaevna [1]

The discount is 30%

Step-by-step explanation:

Given

Price of tape = $60

Discount = $18

In order to find the percentage, we will use the percentage formula

$Percentage = \frac{discount}{Price}*100\\= \frac{18}{60} *100\\=0.3 * 100\\= 30\%$

Hence,

The discount is 30%
