Answer:
45 when a=5 and 7 when b=3
Step-by-step explanation:
Sorry if its wrong
5.... this is a weird question.. <span />
It’s -6/77 seconds because the line segment of km is given 11
First, let's put the second equation, <span>x-2.23y+10.34=0, in terms of y:
x - 2.23y +10.34 = 0
2.23y = x + 10.34
y = .45x + 4.64
Now we can substitute the right side of this equation for y in the first equation
</span><span>y=2x^2+8x
.45x + 4.64 = 2x^2 + 8x
Turn it into a quadratic by getting 0 on one side:
2x^2 + 8x - .45x - 4.64 = 0
2x^2 + 7.55x - 4.64 = 0 Divide both sides by 2
x^2 + 3.76x - 2.32 = 0
x =( -b +/- </span>√(b² - 4ac) ) / 2a
x =( -3.76 +/- √(14.14 + 9.28)) ÷ 2
x = .54 or -4.31
Plug the x values into y = .45x + 4.64
y = .45 (.54) + 4.64
y = 4.88 when x= .54
y = .45 (-4.31) + 4.64
y = 2.70 when x= -4.31
Solution set:
{ (0.54, 4.88) , (-4.31, 2.70) }
The statement that best explains the effects of specializations in the US are:
- The Midwest became a major grain-growing region of the United States. (Option B)
- The north became dependent on workers who migrated from the South. (Option C)
- The northeast became a center for manufacturing and industry. (Option F)
<h3>What is specialization in economics?</h3>
Specialization refers to the act of strategy of focusing on one's area of strength.
For a country, that would mean focusing on the production of goods and services in which it has a higher degree of advantage or efficiency.
