What is the solution of the system? Use any method.<br><br> 3x + 2y = 7<br> y = –3x + 11

Gnom [1K]

Answer:

$(5,-4)$

Step-by-step explanation:

SOLVE BY SUBSTITUTION:

STEP 1: Replace all occurrences of $y$ with $-3x+11$ in each equation.

$-3x+22=7\\y=-3x+11$

STEP 2: Solve for $x$ in the first equation.

$x=5\\y=-3x+11$

STEP 3: Replace all occurrences of $x$ with $5$ in each equation.

$y=-4\\x=5$

determine if the given point is a solution of the given system of linear equations y=3× + 6 y= -2× + 9 (3,3)

Anna11 [10]

Answer:

The point (3, 3) is not a solution of the first equation, therefore is not a solution of the given system of equations.

Step-by-step explanation:

$y=3x+6\ and\ y=-2x+9$

$(3,\ 3)\to\text{put x = 3 and y = 3 to the equations of the functions}\\\text{and check the equality.}\\\\y=3x+6\\\\3=3(3)+6\\3=9+6\\3=15\qquad\text{FALSE!}$

Factor x^3 -4x^2 -3x +18 =0

earnstyle [38]

Answer:

none of the above

Step-by-step explanation:

A graphing calculator shows the zeros to be x=-2, and a double zero at x=3. Hence the factorization is ...

(x +2)(x -3)^2 = 0

The premise that 4 is a zero is incorrect, and none of the answer choices include (x+2) as a factor. The problem is unworkable as written here.

the length of a rectangular poster is 10 inches longer than the width. if the perimeter of the poster is 124 inches, what is the

Jlenok [28]

The formula for the perimeter is 2L + 2W.

Since we know that L=10+W, we can substitute this into the equation.

2(10+W) +2W=124

20+2W + 2W=124

4W +20 = 124

4W=104

W=26

Therefore, the width is 26 inches.
