Is ( 0,0) a solution to this system? y&lt;=x^2-4 y&gt;2x-1?
Xelga [282]

Answer:

The point (0,0) is not a solution of the system of inequalities

Step-by-step explanation:

we have

y\leq x^{2} -4 -----> inequality A

y> 2x-1 -----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities

then

the ordered pair must be satisfy the inequalities of the system

Verify

For x=0, y=0

substitute the value of x and the value of y in the inequalkity A and in the inequality B

Inequality A

0\leq 0^{2} -4

0\leq -4 -------> is not true

therefore

The point (0,0) is not a solution of the system of inequalities

A store is having a sale on jelly beans and trail mix. For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is
klasskru [66]
3j+2t=14  subtract 2t from both sides

3j=14-2t  divide both sides by 3

j=(14-2t)/3

...

5j+6t=28, using j found above in this equation yields.

5(14-2t)/3+6t=28  perform indicated multiplication on left side

(70-10t+18t)/3=28  multiply both sides by 3

70-10t+18t=84  combine like terms on the left side

70+8t=84  subtract 70 from both sides

8t=14 divide both sides by 8

t=$1.75, and since j=(14-2t)/3

j=(14-2(1.75))/3

j=$3.50

So a pound of trail mix costs $1.75 and a pound of jelly beans costs $3.50.
