The solution is (1,1)

Step-by-step explanation:

The system of linear equation is

y=-3x+4 and y+\frac{1}{3} y=\frac{4}{3}

Using substitution method, let us substitute y=-3x+4 in the equation

y+\frac{1}{3} y=\frac{4}{3}

-3 x+4+\frac{1}{3}(-3 x+4)=\frac{4}{3}

Multiplying the term -3x+4 by \frac{1}{3}, we get,

-3 x+4-x+\frac{4}{3}=\frac{4}{3}

Subtracting both sides by \frac{4}{3},

-3x+4-x=0

Simplifying, we get,

\begin{aligned}-4 x+4 &=0 \\-4 x &=-4 \\x &=1\end{aligned}

Now, substitute x=1 in y=-3x+4

y=-3(1)+4\\y=-3+4\\y=1

Thus, the solution is (1,1)

andre [41]

Answer:

90⁰

Step-by-step explanation:

y=cosx

y'= -sinx

eqñ of tangent is y=-x

slope of tangent =-1

we know...

slope of tangent = y' or derivative of y

-sin x = -1

sin x= 1

x = 90⁰

5. Using the factor tree, What are the prime factors of 36
alex41 [277]

Answer:

Step-by-step explanation:

A factor tree is not unique for a given number. Instead of expressing 36 as 2 × 18, we can express 36 as 6 × 6. Prime factorization of 36 using factor tree method is 2 × 2 × 3 × 3 = 2² × 3².
