For this case we have the following expression:

3 (x + 10) + 6 = 3 (x + 12)

We must rewrite both sides of the equation.

For this, we use the distributive property.

We have then:

3x + 30 + 6 = 3x + 36

Adding similar terms we have:

3x + 36 = 3x + 36

We observe that we have two equal equations.

Therefore, the equations intersect for any value of x.

Thus, the equation has infinite solutions.

Answer:

infinitely many

Elis [28]
Let x=distance of foot of ladder from the wall, then
x+2=height of top of ladder up the wall.
length of ladder = 16 feet.
Using Pythagoras theorem, 
x^2+(x+2)^2=16^2, expand and simplify
2x^2+4x+4 = 256 again simplify
x^2+2x-126=0  [fail to factor]
apply quadratic equation:
x=(-2+/-sqrt(4+504))/2
=-1+/-sqrt(127)
x=-12.3 (rejected) or
x=10.27 feet from wall.

What is the equation of a line through point (0,5) that is parallel to the line with equation y= x -7
e-lub [12.9K]

Answer:

y=x+5

Step-by-step explanation:

Lines are parallel if they have the same slope, the Y-intercept does not matter. Since these line passes through point (0,5) it's y-intercept has to be 5 and It's still parallel with line y=x-7.

Answer:

40 people who don't like any of the three drinks.

Step-by-step explanation:

It is given there are 340 people in total

Number of people like tea=150

Number of people like tea only =90

Number of people like coffee only =80

Number of people like milk only =70

Number of people like coffee and milk only = 0

We can draw Venn diagram which helps us to find the number of people who don't like any of these three drinks. I'll attach the file.

Solve 2x+7=3, its because of my homework is a level higher than it shpuld be.​
Kipish [7]

2x+7=3

move 7 to the other side

sign changes from +7 to -7

2x+7-7= 3-7

2x= 3-7

2x= -4

divide both sides by 2 to get x by itself

2x/2= -4/2

answer:

x= -2
