Answer:
1. 80%
2. 12.5%
3. 10%
Step-by-step explanation:
The figure contains 100 equal squares, so the number of squares shaded is equal to the percentage of squares shaded.
La ecuación para la relación entre la distancia y el número de segundos: y =-25x+160.
<h3>Ecuación para la relación entre la distancia</h3>
x=0, y=160m
x=3, y=85m
Dónde:
x=Tiempo
y=velocidad
El primer paso es encontrar el tiempo
Tiempo = (85-160m)/ 3s
Tiempo=-75m/3s
Tiempo=-25 m/s
El segundo paso es crear la ecuación
y =-25x+160
Por lo tanto la ecuación de la relación entre la distancia y el número de segundos: y =-25x+160.

Answer:
f=4
Step-by-step explanation:
-11f = 7(1-2f)+5
step 1 distribute what is outside of the parenthesis to the inside of the parenthesis
-11f=7-14f+5
step 2 combine like terms
-11f=12-14f
step 3 add 14 to each side
3f=12
step 4 divide each side by 3
f=4
When you simply the expression it’s 16
Answer:
4. No solution
Step-by-step explanation:
To solve a system of equations, find the (x,y) solution that satisfies both equations. One method that can be used is substitution. It is done by substituting one function into the other function and simplify.
Substitute y = 4x - 6 into 8x - 2y = 14.
8x - 2(4x - 6) = 14
8x - 8x + 12 = 14
12 = 14 FALSE
Since the variable was eliminated and a false statement was found, there is no solution to this system.
Solve 3 and 5 similarly. If the variable is eliminated again, but a true statement is fund then the solution is infinite. If the variable is not eliminated then substitute it back into one equation to find the other.
