Answer:
Well i believe the answer is obtuse
Step-by-step explanation:
Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved
Pedro must make $330 on the 6th day to have a mean average of $200.
Step-by-step explanation:
<u>Formula for Mean Average</u>
Mean Average = 
<u>DATA:</u>
1st day = $120
2nd day = $110
3rd day = $200
4th day = $300
5th day = $140
6th day = x
<u>Solution:</u>
Mean Average =
200 = 
200*6 = 870+x
1200 - 870 = x
x = 330
Pedro must make $330 on the 6th day to have a mean average of $200.

Answer: 4
find the largest number (5) and take away the smallest (1)
5-1=4
Answer:
The functional expression can be simplified by substituting the given value in the function in place of the variable.
For example, if {eq}f(x)=x^{2} {/eq} be a function then {eq}f(2) {/eq} is determined by plugging {eq}x=2 {/eq} in the function.
Step-by-step explanation:
The given function is:
{eq}f(x) = 4x^{2} + 2x {/eq}
Let {eq}y=\frac{f(x + h) - f(x)}{h} {/eq} then we have:
{eq}\\\\\begin{align*} y & = \frac{4(x+h)^{2} + 2(x+h)-(4x^{2}+2x)}{h} \\\\ & = \frac{4(x+h)^{2} + 2(x+h)-(4x^{2}+2x)}{h} \\\\ & = \frac{4(x^{2}+2xh+h^{2}) + 2x+2h-4x^{2}-2x}{h} \\\\ & = \frac{4x^{2}+8xh+4h^{2}+ 2h-4x^{2}}{h} \\\\ & = \frac{8xh+4h^{2}+ 2h}{h} \\\\ & = \frac{h(8x+4h+2)}{h} \\\\ & = 8x+4h+2 \\\\\end{align*} {/eq}
