What is fhe solution of the system of these equations? (i’m giving brainliest)

fgiga [73]

Answer:

Top-left system: (3,5)

Bottom-right

system: (-1,0)

Step-by-step explanation:

One way to solve a system of equations is to graph them. The solution is the point of intersection (where the lines cross). If you need to give the x-value and y-values separately, the first number in the pair is the x and the second number is the y.

For g(x) = -3x + 1 Find x if g(x) = 16

Luda [366]

Answer:

=-5

Step-by-step explanation:

16=-3x+1

Subtract 1 from both sides

15=-3x

Divide both sides by -3 to isolate x

x=-5

A and b are positive integers and a–b = 3. Evaluate the following:<br> 27/1/3 b/9/ 1/2 a

DaniilM [7]

Answer:

$\dfrac{1}{27}$

Step-by-step explanation:

Given that,

a-b = 3

We need to find the value of $\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}$ .

We know that,

$27=3^3\\\\9=3^2$

So,

$\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}=\dfrac{3^3^({\dfrac{1}{3}b})}{3^2^{\dfrac{1}{2}a}}\\\\=\dfrac{3^b}{3^a}$

We know that : $\dfrac{x^p}{x^q}=x^{p-q}$

So,

$\dfrac{3^b}{3^a}=3^{b-a}$

Since, b-a = -3. So,

$3^{b-a}=3^{-3}\\\\=\dfrac{1}{3^3}\\\\=\dfrac{1}{27}$

So, the value of the given expression is equal to $\dfrac{1}{27}$ .

What is the rate of change

Serggg [28]

Answer:

Slope = 0

Step-by-step explanation:

Let's use the equation $\frac{y2 - y1}{x2 - x1}$ for this problem.

We have two points: (2,0) and (-2, 0)

Let's plug them both into the equation shown above.

$\frac{0 - 0}{-2 - 2}$

Solve.

0 - 0 = 0

-2 - 2 = -4

$\frac{0}{-4}$ = $-\frac{0}{4}$ = 0

A zero in the numerator means this equation has a slope of 0.

Any line with a slope of 0 is a horizontal line.

Slope (rate of change) = 0
