A linear equation, will make a straight line, an exponential will increase exponentially, making curves rather than straight lines.

Determine the slope of the line that passes through the points (-4, 6) and (0, 4).

Dennis_Churaev [7]

Slope = rise/run = (change in y)/(change in x)
Slope = (4-6)/(0-(-4)) = (-2)/(4)
Slope = -1/2 = -0.5

Answer:

Step-by-step explanation:

Given:

AB ≅ BC

AK ≅ KC

∠AKE ≅ ∠CKP

To Prove:

ΔAKE ≅ ΔCKP

Statements Reasons

1). AB ≅ BC 1). Given

2). ∠BAC ≅ ∠BCA 2). Property of Isosceles triangles

3). ∠EKA ≅ ∠PKC 3). Given

4). ΔAKE ≅ ΔCKP 4). ASA Postulate of congruence

Hence ΔAKE ≅ ΔCKP.

What is the standard form of 5x^2+5y^2-10x+20y-30=0

o-na [289]

$5x^2+5y^2-10x+20y-30=0$

We need to get the equation in square form

We apply completing the square method

$5x^2-10x+5y^2+20y-30=0$

Divide all the terms by 5

$x^2-2x+y^2+4y-6=0$

Group x terms and y terms separately

$(x^2-2x)+(y^2+4y)-6=0$

By completing the square method, we take half of coefficient of x and square it

$\frac{-2}{2} = -1$

square it $(-1)^2= 1$

Add 1 on both sides

$(x^2-2x+1)+(y^2+4y)-6=+1$

$\frac{4}{2} = 2$

square it $(2)^2= 4$

Add 4 on both sides

$(x^2-2x+1)+(y^2+4y+4)-6=0+1+4$

Add 6 on both sides

$(x^2-2x+1)+(y^2+4y+4)=6+1+4$

Now factor both parenthesis

$(x-1)^2+(y+2)^2=11$

The equation of the circle is $(x-1)^2+(y+2)^2=11$

Help me please answer this question

Marianna [84]

The whole angle is 90 degrees and you have 45 so 90-45 = your answer :)
