What type of system of linear equations is this? y = –5x – 4
y=1/2x+3
-----------------
A. consistent and independent
B. consistent and dependent
C. inconsistent
D. independent and inconsistent

(this is all the ino the question gives me, there's no graph or anything)

Answers

y = -5x - 4....slope = -5 and y int = -4
y = 1/2x + 3...slope = 1/2 and y int = 3

if the slopes and the y intercepts are different, then there is 1 solution making this independent and consistent

Answer:

Option A is correct.

Step-by-step explanation:

y =-5x -4

y= $(1)/(2)$ x+3

As we know that slope intercept form of line is y =mx+b

where m = slope and b = Y intercept.

on comparing the equations given with standard equation ,we get

for first equation ; slope = 5 and Y intercept = -4

for Second equation; slope = $(1)/(2)$

And we know that if slope and Y intercept of two equations are distinct

then solution is consistent and independent .

Here we can see that slope and intercept of both equations are different

therefore system of equations is consistent and independent.

option A is correct.

If two figures are similar, the resulting corresponding angles are always enlarged reduced congruent similar

Answers

If two figures are similar, the resulting corresponding angles are CONGRUENT.

Congruent means exactly equal in size and shape. Congruent angles have the exact same measure.

Two figures are similar when its corresponding angles have the same exact measure.

the answer is congruent. I just took the quiz and I got it right hope this helps!

A bus and a car leave from the same city traveling in opposite directions. The bus leaves 2 hours before the car does. The bus travels at a steady speed of 50 mph while the car travels at 70 mph. After how many hours will the bus and car be 800 miles apart?If h represents the number of hours the bus travels, then which of the following expressions represents the number of miles the car travels?

a.70(h + 2)
b.70(h - 2)
c.70h

Answers

The formula for this equation would be B. 70(h - 2)

Answer:

70(h-2) is the correct answer

Express one-third of a complete angle into radian

Answers

Answer:

0.66667π radians

Step-by-step explanation:

1/3 = 0.33333

One-third of a complete angle in radians would be:

0.33333 · 2π ≈ 0.66667π radians

So, the answer is 0.66667π radians

Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level. 7h – 5(3h – 8) = –72Which statement is true about Pieter’s solution?
1. It cannot be a fraction or decimal because the depth of the well is a whole number.
2.It must be a positive number since it represents a number of hours.
3. It must be a negative number because the depth is below sea level.
4.It cannot be greater than –72 because that is the depth of the well.
