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.

Which is true regarding the graphed function f(x)?
Sladkaya [172]
<h2>Explanation:</h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:

f(x)=\left(x-4\right)^{2}+5

So this is the equation of a parabola that opens upward and whose vertex lies on the point:

V(4,5)

The graph of this function is shown below. Which is true regarding the graphed function f(x)?

  • It is true that the domain is the set of all real numbers because this is a polynomial function.

  • It is true that the range is the set of all real numbers such that y ≥ 5

  • It is true that this parabola opens upward

  • It is true that it doesn't cut the x-axis

Find the missing exponent. 2^{3}\cdot 2^{?}=2^{10}2
guapka [62]

Answer:

7

Step-by-step explanation:

2^3 • 2^7 = 2^10

When multiplying exponents, the exponents add up together. In other words, just subtract 10-3 = 7 that would be your missing exponent!

Hope this helps, good luck!
