Which is the equation of a line that has a slope of -2/3 and passes through point (–3, –1)?
emmainna [20.7K]

Answer:

y = (-2/3)x-3

Step-by-step explanation:

Hello:

equation is the line is : y = ax+b        a is a slope

y = (-2/3)x+b

passing through the point (−3;−1) :   -1 =(-2/3)(-3)+b    so : b = -3

y = (-2/3)x-3

second solution : you can verify (-3 ; -1) in the equation : y = (-2/3)x-3

Which situation shows a constant rate of change?
lara31 [8.8K]

The <em><u>correct answer</u></em> is:

D) The amount a person pays for gas compared with the number of gallons purchased

Explanation:

A constant rate of change means that for every x, y increases the same amount.

In the situation "The amount a person pays for gas compared with the number of gallons purchased ," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid.  Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount.  This means it has a constant rate of change.

Elaborati un desen : punctul m este mijlocul bazei triunghiuluibisoscel abc
blondinia [14]
Uh .. Nu vorbesc limba română, dar am încercat meu cel mai bun pentru a face această întrebare.

Teorema: Fie ABC un triunghi isoscel cu AB = AC. Fie M denota punctul central al BC (adică, M este punctul pe BC pentru care MB = MC). Apoi
a) Triangle ABM este congruent cu ACM triunghi.
b) Unghi ABC = ACB Angle (unghiuri de bază sunt egale)
c) Unghi AMB = Unghi AMC = unghi drept.
d) Unghi BAM = unghiul CAM


Corolar: Prin urmare, din aceste fapte și definițiile:
Ray AM este unghiul bisectoarea unghiului BAC.Linia AM este altitudinea triunghiului ABC, prin A.Linia AM este mediatoare BSegmentul AM este mediana triunghiului ABC, prin A.Dovada # 1 din Teorema (după B & B)
Lasa bisectoarea unghiului de BAC se intersectează segmentul BC la punctul D.
Din moment ce raza AD este unghiul bisectoare, unghiul BAD = unghiul CAD.Segmentul AD = AD = sine.De asemenea, AB = AC deoarece triunghiul este isoscel.Astfel, triunghiul BAD este congruent cu CAD de SAS (side-unghi-side).

olga_2 [115]

Answer:

x^4+x³+7x²-6x+1

Step-by-step explanation:

(x²+2x+8)(x²-x+1)

distribute

x²(x²-x+1)

x^4-x³+x²

2x(x²-x+1)

2x³-2x²+2x

8(x²-x+1)

8x²-8x+1

x^4-x³+x²+2x³-2x²+2x+8x²-8x+1

combine like terms

x^4+x³+7x²-6x+1
