How is a system of two linear inequalities in two variables different to a system of two linear equations in two variables? Choo

se the correct answer
OA A system of two linear inequalities is different from a system of two linear equations. It is not possible to have no solution for a system of two linear
inequalities while a system of two linear equations it is
OB. A system of two linear inequalities is different from a system of two linear equations. A system of two linear inequalities does not have to be equivalent to
have infinitely many solutions while a system of two linear equations does need to be equivalent.
OC. A system of two linear inequalities is different from a system of two linear equations. The solution to a system of two linear inequalities is the point of
intersection while the solution to a system of two linear equations is a shaded region
OD. A system of two linear inequalities is different from a system of two linear equations. A system of two linear inequalities always has more than one solution
while there can only be one solution to a system of two linear equations

Intercepts are when one value is 0...like when x is 0, the point would be the y intercept....
x intercept is 4 
y intercept is 5

slope:  y2 - y1/x2 - x1
slope = 0 - 5/4 - 0
slope = -5/4

the for the equation plug in any points from the line.

y = mx + b
5 = -5/4(0) + b
5 = B

y = -5/4x + 5 is the equationh to the line

You buy a container of cat litter for $11.50 and a bag of cat food for x dollars. The total purchase is $16.80, which includes 5
Anni [7]

let cat food = x

 total plus 5% = 105% = 1.05

1.05 * (11.50 + X) = 16.80

12.075 + 1.05x = 16.80

1.05x = 16.80-12.075

1.05x = 4.725

x = 4.725 / 1.05

x= 4.50

 the cat food cost $4.50


11.50 +4.50 = 16.00

16.00 * 0.05 = 0.80

16.00 + 0.80 = 16.80

PLease help me it says use cosine law
zubka84 [21]

Answer:

59 degrees

Step-by-step explanation:

law of cosines states that

for sides A B C and angle c opposite to side C,

C = \sqrt{A^2 + B^2-2ABcos(c)} \\cos(c) = \frac{c^2-a^2-b^2}{-2ab}

cos(b) = \frac{13^2-6^2-15^2}{-2(6)(15)} = 23/45

cos-1(23/45) = b

b = 59

On a number line, show all values of x for which…<br> |x |&lt; 1
aleksley [76]

Answer:

See attachment

Step-by-step explanation:

We want to show all values of x, for

|x| \: < \:  1

on the number line.

By the definition of absolute value function:

- x \:  <  \: 1 \: or \: x \:  <  \: 1

Divide through the first inequality by -1 and reverse the sign.

x \:   >  \:  - 1 \: or \: x \:  <  \: 1

On the number line, we can represent this as shown in attachment.
