Answer:
8 mangoes
Step-by-step explanation:
1) lets create 2 systems of inequalities
where m=# of mangoes
p=# of peaches
so m+p≥15 and 1m+0.5p≤15
lets substitute "13" in the m+p inequality to see how many mangoes dylan can buy:
m+(13)≥15
subtract "13" from both sides:
m≥2
now we substitute "13" in the other inequality:
m+0.5(13)≤15
m+6.5≤15
subtract 6.5 from both sides:
m≤8.5
m≥2 and m≤8.5
seeing our restriction, we can buy 8 mangoes (since we can't have 1/2 a mango)
hope this helps!
The inequality
can be used to find the domain of ![f(x)=\sqrt{x-3}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%7Bx-3%7D)
Answer: Option B
<u>Step-by-step explanation:</u>
We have
, domain is the set of all possible x-values which will make the function "work", and will output real y-values. Basically to find domain of any function means to find range of values of x that will give real values of y.
For the equation
, we know that there's no value ( iota or complex numbers are there but here we will deal with real numbers ) of negative numbers under square root
∴
must be greater than or equal to 0.
⇒ ![x-3 \geq 0](https://tex.z-dn.net/?f=x-3%20%5Cgeq%200)
4:1.
56,000÷2 = 28,000
14,000÷2 = 7,000
28,000/7,000 = 28/7
28 ÷ 7 = 4
---- -----
7 ÷7 = 1
4:1

<em>Answer:</em>
<em>The cost of the racquet is $135</em>
<em>Step-by-step explanation:</em>
<em>Let</em>
<em>x-----> the cost of the racquet</em>
<em>we know that</em>
<em>The racquet represent the 100%</em>
<em>so</em>
<em>using proportion</em>
<em />
<em>x/100%= $9.45/7%</em>
<em>x=100%*($9.45)/7</em>
<em>x=$135</em>
