1) y=3x-4
When x increases by 1, y increases by 3 so the slope is rise/run → 3
y-int is -4 bc y-value is -4 when x=0

2)y=-3x+4
When x increase by 2, y decreases by 6 so the slope is rise/run → -3
y-int is 4 bc y-value is 4 when x=0

3)y=-1/3x+4
When x increase by 3, y decreases by 1 so the slope is rise/run → -1/3
y-int is 4 bc you now have the equation y=-1/3x+b and u just have to plug in random point from the graph, so ex, 6 into x and 2 into y. You can get 4 as b in the equation.

4)y=1/3x-4
When x increases by 6, y decreases by 2 so the slope is rise/run → 1/3
y-int is -4 bc u do the same thing as 3)
For ex, plug in 6 for x and -2 for y and you can get -4 as the b in the equation.

If angle y measures 65 degrees how much does x measure?
belka [17]

Answer:

supplementary angles add up to 180°

given y=65° thus...

x+y=180°

x + 65°=180°

x=180°- 65°

x=115°

Name the type of polynomial indicating the
lutik1710 [3]

first off, bear in mind that the  terms are usually separated by a + or a - sign.

secondly, the degree of a term of a polynomial comes from the sum of its variables' exponents.

a)

\bf 2x^3y^2\qquad \begin{cases} \textit{no + or - signs, just one term a \underline{monomial}}\\\\ x^3y^2\implies \stackrel{degree}{3+2}\implies 5 \end{cases}

b)

\bf \stackrel{term}{5x}+\stackrel{term}{3x^2}-\stackrel{term}{9}\qquad \begin{cases} \textit{three terms, a \underline{trinomial}}\\\\ 5x^1\implies 1\\ 3x^2\implies 2\qquad \stackrel{\textit{degree of the polynomial}}{\textit{term with highest degree}}\\ \end{cases}

Two angels in a triangle add up two 115 degrees what is the size of the third angle
Bogdan [553]
The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle

solve
115+z=180
subtract 115 from boths ides
z=65

answer is third angle=65 degrees
