Answer:
best answer is correct so C and D
Step-by-step explanation:
d.(0, 4) C. (-1 ,2)
D.0 is less than or equal to 2x-3
0 is than or equal to 5
plugging in others
A. 1 is less than or equal to 2(-1)-3
1 is greater than -5
B. 3 is less than or equal to 2(0)-3
3 is greater than -3
C. -1 is less than or greater to 2(2) -3
-1 is less than or equal to 1
The answer is A.
D= 6<=x<=11
Answer:
<em>The value of the expression is 11</em>
Step-by-step explanation:
<u>Evaluate Expressions</u>
An algebraic expression consists of a set of variables and constants related by algebraic operations like addition, subtraction, multiplication, etc.
To evaluate an algebraic expression, we replace the variables for the constant value they are assigned.
Let's consider the expression:
for x=10, y=-1, z=0
Substituting the variables for their values:
The value of the expression is 11
When the height is 0 that is when it hits the ground
solve
0=-16t²+25x+3
cant factor so use quadratic formula
for
0=ax²+bx+c
so for
0=-16t²+25t+3
a=-16
b=25
c=3
so
it has to be a positive time
so it will hit the ground after
seconds
If the length is 3×width then length+width=4×width and the perimeter is 8×width=86, width=86/8=43/4=10.75cm.
The length is 3×10.75=32.25cm.
