Answer:

solution of the given system of equation is (4,7)

C is the correct option.

Step-by-step explanation:

The given system of equations is

2x+3y=29...(i)\\\\x=4...(ii)

Substituting the value of x from (ii) in equation (i)

2\cdot4+3y=29\\\\8+3y=29\\\\3y=21\\\\y=7

Therefore, the solution of the given system of equation is (4,7)

C is the correct option.

How do you find the end behavior?
Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

In this lesson, you will learn what the "end behavior" of a polynomial is and how to analyze it from a graph or from a polynomial equation.

What's "end behavior"?

The end behavior of a function

f

ff describes the behavior of the graph of the function at the "ends" of the

x

xx-axis.

In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the

x

xx-axis (as

x

xx approaches

+

∞

+∞plus, infinity) and to the left end of the

x

xx-axis (as

x

xx approaches

−

∞

−∞minus, infinity).

yyxxy=

f(x)

y=f(x)

x gets

x gets

more

+ more +

f(x) gets

f(x) gets

more

+ more +

For example, consider this graph of the polynomial function

fff. Notice that as you move to the right on the x

xx-axis, the graph of f

ff goes up. This means, as x

xx gets larger and larger,

f(x)

f(x)f, left parenthesis, x, right parenthesis gets larger and larger as well. Mathematically, we write: as

x→+x→+∞x, right arrow, plus, infinity,

f(x)→+∞

f(x)→+∞f, left parenthesis, x, right parenthesis, right arrow, plus, infinity. (Say, "as xxx approaches positive infinity, f(x)

f(x)f, left parenthesis, x, right parenthesis approaches p

Old Shark Tank Length: 20 meters Width: 4 meters Helght: 10 meters Terrence knows that each shark needs 25 cubic meters of space
schepotkina [342]

Answer:

volume of old tank=20×4×10=800m³

no of shark adjust =800/25=32 sharks is adjusted in old shark tank

for new

if length=25℅0f 20+20=25m

breadth=25%of 4 +4=1+4=5m

height is same=10m

new volume =25×5×10=1250m³

total no.of shark adjust=1250/25=50 shark

50-32=18 more shark that the new tank hold.
