What is -31+-4x=-5+-5(1+5x)

Mathematics
1 answer:
aliya0001 [1]3 years ago
5 0

Answer:

x=1

Step-by-step explanation:

-31+(-4x) = -5+(-5)(1+5x)

-31-4x = -5+(-5)+(-25x)   : Adding a negative is the same as subtracting and I distributed the -5

-31 = -5 + -5 -21x    : added 4x to both sides

-31 = -10 -21x       : added -5 and -5

-21 = -21x           : added 10 to both sides

x=1   : divided both sides by -21, division of 2 negatives is a positive

Consider the graph of the linear function h(x) = –x + 5. Which could you change to move the graph down 3 units?
Yakvenalex [24]
I don't see a b or an m in this function, but generally, a linear function is of the form ax+b. The b in this equation (not sure if it is the same as your b), controls the shift of the function. Lower b by 3, the graph shifts down by 3.

So unless there is a minus sign before b, it has to be lowered by 3. (If there is a minus sign, it has to be increased by 3).

Solve for x in the triangle above
faust18 [17]

Answer:

x = 30

Step-by-step explanation:

The interior angles of a triangle must always add up to 180.

2x + 2x + 3x - 30 = 180

Add 30 to both sides to seperate variables.

2x + 2x + 3x = 210

Combine like terms.

7x = 210

Divide by 7 to isolate x.

x = 30
