Answer:

the vertex is (1,-1)

Step-by-step explanation:

y = −3x^2 + 6x − 4

the vertex is at

h= -b/2a where ax^2 +bx+c

h= -6/2(-3)

h= -6/-6

h=1

substitute this in to find the y value

y = -3(1)^2 +6(1)-4

y = -3+6-4

y = -1

the vertex is (1,-1)

Can someone help me asap ? (solving a system by substitution)

Scilla [17]

The short answer is to solve one equation for one variable, then swap that variable in a different equation.

Example:
2x + 2y = 6
y-x = 1

Step 1: solve either equation for a variable: (#2) y = x+1
Step 2: substitute for your solved variable (I can substitute x+1 for y)

(#1) 2x + 2(x+1) = 6
2x + 2x + 2 = 6
4x + 2 = 6
4x = 4
x = 1

now use x=1 to solve for y in either original equation

<h2>time = 6 years</h2>

Step-by-step explanation:

<h3>interest (i) = (p × r × t)÷100</h3><h3>$825 = ($2500 × 5.5 × t) ÷ 100</h3><h3>$82500 = $2500 ×5.5 × t</h3><h3>t = 82500÷(2500 ×5.5)</h3><h3>t = 82500÷13750</h3><h3>t = 6</h3>
