Tell whether the system has one solution, infinitely many solutions, or no solution.
nadya68 [22]
X=-7y+34
x+7y=32

To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32

So the correct answer would be no solution because it's the same problem and it can't equal to different answers.

Can someone help me really please
JulsSmile [24]

Answer:

26

Step-by-step explanation:

Let x represent the missing number

8\frac{11}{15} = 7\frac{x}{15}

Convert both fractions to improper fractions

\frac{131}{15} = \frac{105 + x}{15}

Cross multiply

15(105 + x) = 15(131)

1,575 + 15x = 1,965

Subtract both sides by 1,575

15x = 1,965 - 1,575

15x = 390

Divide both sides by 15

x = \frac{390}{15}

x = 26

How many zeros does the function ????(x) = 3x^2 + 6x + 2 have? Explain how you know.
maxonik [38]

Answer:

The function has 2 zeros:

x = -1 - \frac{1}{\sqrt{3}}\\x = -1 + \frac{1}{\sqrt{3}}

Step-by-step explanation:

When you have a polynomial function, you can identify the grade of the function (the grade is the maximum potency) and this is the number of zeros that the function will have. In this case, you have a second-grade polynomial function that has 2 zeros.
