The answer is: [A]: " 8m − 3 " .
_________________________________________________
Explanation:
_________________________________________________
(m² + 5m − 7) − (m² − 3m − 4) =
(m² + 5m − 7) − 1(m² − 3m − 4) =
(m² + 5m − 7) − 1m² + 3m + 4) =
m² + 5m − 7 − m² + 3m + 4 ;
________________________________________
Now, combine the "like terms" :
________________________________________
m² − m² = 0 (cancel out).
+5m +3m = +8m ;
− 7 + 4 = -3 ;
________________________________________
And we are left with:
________________________________________
" 8m − 3 " ; which is: Answer choice: [A] .

Answer:
Buenos días;
1) La ecuación de la velocidad en un movimiento uniformemente acelerado (M.U.A) es:
V=V₀+at.
V=30 m/s-2 m/s².t
Ahora elimina las unidades (m/s, m/s₂), y tendrás la ecuación de la velocidad en función del tiempo.
V(t)=30-2t.
Sol: la ecuación de la velocidad en función del tiempo es : V(t)=30-2t.
2) La ecuación de la posición en función del tiempo en un M.U.A es:
X=X₀+V₀.t+(1/2).a.t²
X=0+30 m/s.t+(1/2).(-2 m/s²).t²
Eliminas las unidades, y tendrás la ecuación de la posición en función del tiempo.
X(t)=30.t-t².
Sol: la ecuación de la posición en función del tiempo es: X(t):30t-t²
Un saludo.

Answer:
Slope = 6.25
Y-intercept = 8.50 or 8.5
Equation: y = 6.25x + 8.50 or y = 6.25x + 8.5
Proportional = No
Step-by-step explanation:
The slope is also the rate of change and the question states that Kayla earned $6.25 an hour. So your slope also known as rate of change is 6.25.
Your y-intercept is the starting point and in the question it states that Kayla received $8.50 in tips. So your y-intercept also known as starting point is $8.50.
The Equation is meant to be set-up like this:
y = mx + b which is y = slope + y-intercept
Since $6.25 is our slope and $8.50 is our y-intercept lets arrange it:
y = 6.25x + 8.50
A proportional graph is a graph that has the line drawn from the equation going through the origin which is (0,0) the middle intersection between the y and x line. So with that being said the graph is not proportional because it doesn't go through the origin.
How do I know this?
I know this because the starting point in the equation that I graph is 8.50 or 8.5 and it does not start from (0,0) or 0 so it does not cross the (0,0) point.
Answer:
(-3,2)
Step-by-step explanation:
Translate 2 units up means add 2 to the y coordinate.
X=7 and y=4 are the correct equations
