PLEASE HELP ME RN PLEASE

Advocard [28]

Answer:

$\frac{n^{2} - 1 }{2}$

$\sqrt{29}$

Step-by-step explanation:

Area of triangle=1/2×b×h

$\frac{1}{2} \times (n - 1)(n + 1)$

$\frac{( {n}^{2} + n - n - 1) }{2 }$

$\frac{ {n}^{2} - 1 }{2}$

2. Area of triangle=14

$\frac{ {n}^{2} - 1 }{2} = 14$

${n}^{2} - 1 = 28$

${n}^{2} = 29$

$n = \sqrt{29}$

please rate well and mark BRAINLIEST.

thanks

Use the graph to write an equation that represents the relationship between X and Y.

Yuki888 [10]

Answer:

The equation is $y=x-3$

Step-by-step explanation:

Observing the graph

Let

$A(3,0), B(15,12)$

step 1

Find the slope m

$m=(12-0)/(15-3)=12/12=1$

step 2

Find the equation of the line into point slope form

$y-y1=m(x-x1)$

with the point $A(3,0)$ and the slope $m=1$

substitute

$y-0=(1)(x-3)$

$y=x-3$

What is the domain of the function f(x) = x2 + 3x + 5

Roman55 [17]

The domain of the function is defined as x-values that result in valid y-values. In this case, the domain -∞ < x < ∞ satisfies the function because all real numbers in x result in a real y-value.

I need help with this, I don't got it

Brrunno [24]

Answer:

slope is -4/3 and y-int is -1

Step-by-step explanation:

Solve for y

3y = -3 - 4x

y = -4x/3 - 1

so the slope is -4/3

the y intercept is -1

Start by making a point at (0,-1), then count 4 down and 3 to the right and make another point. Continue to do this until you have a line long enough.
