Answer:

A. 28.1 cm^2

Step-by-step explanation:

a = bh

a = (7.6)(3.7)

a = 28.12 cm^2

a = 28.1 cm^2

Cassandra and Yvette each have a calculator. Yvette starts at a 100 and subtracts 7 each time. Isandro starts at zero and adds 3

34kurt

This can be be solved the following way:
Yvette starts at 100 and subtracts 7 k times, as for Cassandra (or Isandro, the question is not clear on this) she starts at 0 and presses adds 3 k times. This leads to the following equation:
$100-7k=3k$
$100=10k
\\
10=k$
So for k=10 they will both display the same number.
We can now either choose the viewpoint of Cassandra or Yvette:
If we chose Yvette then we'll have $100-7*10=30$ and for Cassandra we have, $3*10=30$ .

What is the snswer to this qustion if you answer this thanks

Svetradugi [14.3K]

18-inch piece per present.

There are 7 presents

That means the total amount needed would be 18 * 7 = 126

The person has 120. 120 is less than 126, so no there isn't enough.

What is the equation of the axis of symmetry of the graph of y+3x-6=-3(x-2)2+4

eimsori [14]

A graph shows the vertex to be at (1.5, 4.75).

The equation of the axis of symmetry is x=1.5.

_____
If you want to find it analytically, you can put the equation in standard form.
y = -3(x -2)² +4 -(3x -6)
y = -3x^2 +9x -2
This is of the form y = ax² +bx +c with a=-3 and b=9. The axis of symmetry is given by ...
x = -b/(2a) = -9/(2×(-3)) = 3/2 . . . . . same as above

50 POINTS FOR WHOEVER CAN ANSWER THESE! LOOK AT THE IMAGES! SYSTEMS WITH INEQUATIONS!

hichkok12 [17]

We have that

1)which ordered pair is a solution to the system of inequalities ?
y<3 and y>=-x+5

using a graph tool
the solution is the pair (6,1)---------> see the attached figure

2) the ordered pair (-3.0) is a solution of witch system?
the answer is
the pair (-3,0) is solution of the systems

y<0 y<x+9----------> see the attached figure
and
y>0 y<x+9----------> see the attached figure

3))which ordered pair is a solution to the system of inequalities ?
y<=abs(x) y<-2x-1
the solution is the pair (-3,1)---->see the attached figure

4)what is the solution of the system of equations?
the solution is the point (3,2,1)-----> see the attached figure
2x+y-z=7-----> 2*3+2-1=7--------> 7=7
-x-2y-2z=-9----> -3-2*2-2*1=-9------> -9=-9
x+3y-3z=6---------> 3+3*2-3*1=6--------> 6=6

5) we have that
-4x-2y=-4-----------------> equation 1
3x-y=13----------> y=3x-13----------> equation 2
substitute 2 in 1
-4x-2*(3x-13)=-4---------> -4x-6x+26=-4-------> -10x=-30-----> x=3
y=3x-13-------> y=3*3-13--------> y=-4
the system has exactly one solution,
therefore
it is independent
