What are two decimals that can be rounded to 4.26

Answers

In rounding, a number must be 5 or more to round up, and 4 or less to round down.

To round up to 4.26 you would need a number between 4.255 and 4.264

4.258 and 4.261 are two examples

Determine whether the table represents a proportional relationship. If a proportional relationship exists, what is the constant ratio of
y
x
?
A) yes;
5
3
B) yes;
3
5
C) yes;
1
3
D) The table does not represent a proportional relationship.

Answers

Answer:

A.

Step-by-step explanation:

Yes, they have a proportional relationship.

The table shows sequences, where x-values increase +3, and y-values increase +5, that is, while x increases 3 unites, y increases 5 units, this ratio between variables can be described as the slope:

$m=(13-(-2))/(12-3) =(15)/(9)=(5)/(3)$

This fraction or ratio is referring to what we said in words, while y increases 5 units, x increases 3 units. We observe that is a positive ration, this means that magnitudes are both increasing.

Therefore, the right answer is the first one A.

A

both the x and y values are increasing at a steady rate (x by 3 and y by 5)

because it’s y/x, you would put the increase in the y value over the increase in the x value

hope that helps :)

Line HF is tangent to circle D at point E. SEgment DE is the radius of circle D, what is true about DEF?A.angle DEF is congruent to angle DEH
B.angle DEF is an acute angle
C.angle DEF is an obtuse angle
D.angle DEF is a straight angle

Answers

When we draw a circle with the centre at D and have a tangent HF to the circle D at point E, the angle DEF will be a right angle.

In other words angle DEF = 90 degrees

Since HF, the tangent, is a straight line, the other angle DEH should also be = 90 degrees because the straight line has an angle of 180 degrees

Therefore angle DEF = angle DEH = 90 degrees

Therefore, angle DEF is congruent to angle DEH (Option A)

D.angle def is an obtuse angle

What is the formula for Slope-Intercept Form of the Line

Answers

It's not the slope-intercept form of the line.

It's the slope-intercept form of the line's equation.

Y = mX + B

'X' is the slope of the line

'B' is the y-intercept of the line

The formula would be : m = [y1 - y2] / [x1 - x2]
