what coefficient would you get for the x terms on the right side of 3x+15=2x+10+x+5
Answers
Answer:
x=0
Step-by-step explanation:
Answer:
Any real number.
Step-by-step explanation:
3x + 15 = 2x + 10 + x + 5
First, add like terms.
3x + 15 = 3x + 15
Subtract 15 on both sides.
3x = 3x
Divide 3 on both sides.
x = x
Since x equals x, you can give any value (any real number) to x.
Since 3x = 3x, you can say x = 1, meaning 3 = 3.
Or, you can say x = 8. 3x = 3x will be 24 = 24.
x can be any number.

is y=-2/5x inverse or direct variation
Answers
Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]

Find the Y intercept
Please help!!!
Answers
Answer:
y - intercept = 8
Step-by-step explanation:
Given
y = (m - 2)(m - 4)
To find the y- intercept, let m = 0 in the equation and solve for y, that is
y = (0 - 2)(0 - 4)
= (- 2)(- 4)
= 8 ← y- intercept or in coordinate form as (0, 8 )

Answers
Answer:
slope = [tex]\frac{12}{7}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 7, - 8) and (x₂, y₂ ) = (0, 4)
m = [tex]\frac{4+8}{0+7}[/tex] = [tex]\frac{12}{7}[/tex]

Mai thinks of a secret number. She says that her secret number is more than 11 units away from 50. Write an absolute- value inequality that gives the possible values of Mai's number.
Answers
Given:
Secret number is more than 11 units away from 50.
To find:
The absolute- value inequality that gives the possible values of Mai's number.
Solution:
Let the secret number be x.
Secret number is more than 11 units away from 50. It may be less than 50 or more than 50.
Case 1: If x<50, then [tex]50-x>11[/tex]
Case 2: If x>50, then [tex]x-50>11[/tex]
It means the absolute difference between secret number and 50 is greater than 11.
[tex]|x-50|>11[/tex]
Therefore, the required inequality is [tex]|x-50|>11[/tex].

m<2 = 100 degrees because angles on a straight line equals 180 degrees.
c.
m<1=75 degrees because again of the alternate angle rule.
m<2= 60 because that angle is equal to diagonally upper angle (I'll call it Z) and that angle would equal 60 because 180-120=60

Answers
Answer: Slope is undefined. x=0
slope calculation: -3-4/0-0 = -7/0 and anything divided by 0 is undefined
the x value in the coordinates is 0 so it’s x=0 line.
vertical lines always have undefined slopes
Answer:
[tex]x=0[/tex]
Step-by-step explanation:
So first of all we need the slope of the line we are trying to findWe get the slope by using the following formula [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] So when you have two pairs of points, it will be [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] so our points are; (0,4) the first point, so [tex]x_1=0,y_1=4[/tex] and(0.-3) the second point, so [tex]x_2=0,y_2=-3[/tex] Put this in our equation [tex]slope=\frac{(-3)-(4)}{(0)-(0)}=\frac{-7}{0}[/tex] Oh no, that can't be right, any number divided by zero is undefined, meaning can't be answered. So this line has no slope So how do we know the equation? Remember, (a) if the line is horizontal, then the slope is 0,(b) if the line is vertical then the slope is undefinedSo our line is vertical, meaning it is an equation of xIf it were horizontal it would be an equation of ySo vertical, it is [tex]x=??[/tex] How do we know what x equals?

Answer:
x= 65 z= 38 y= 77
Step-by-step explanation:
x=65° (opposite angles are equal)
z= 180°-[71+71 (bc the other side is also equal to 71)]
z= 180°-142°=38°
y= 180 - [sum of angle x (65°) and angle z (38°)]
y= 180 - 103= 77°
to make sure ur answer is correct the sum of angle x, y and z MUST = 180
lets check:
65° + 38° + 77° = 180°
