Answer:

1) C 2) (-2,0) 3) 4) 5) c )S={(0,3)} 6) (0,2) 7) 8) Missing graph 9) Vertical line (check below) 10) B 11)

Step-by-step explanation:

1) Solving by the Addition/Elimination Method. Firstly, let's reduce one variable by making some algebraic adjustments and then adding it up:

2) Solving by Substitution Method. Where y=x+2 is plugged in the 2nd equation.

3) Solving it, again, by the Substitution Method due to the I equation form:

4) By the Addition Method

5) To use the graph method to solve the system of Linear equations is possible by graphing each equation on the Cartesian Plane.

Check the graph below, this system has only one solution.

c)S={(0,3)}

Add the fractions and simplify the answer 1/2 +2 /3

IrinaVladis [17]

What we are going to do is add $\frac{1}{2}$ by $\frac{2}{3}$ . The first thing we do is make common denominators for $\frac{1}{2}$ and $\frac{2}{3}$ : $\frac{1*3}{2*3}= \frac{3}{6} \ and \ \frac{2*2}{3*2}= \frac{4}{6}$ . Now we add $\frac{3}{6}$ by $\frac{4}{6}$ : $\frac{3}{6}+ \frac{4}{6}= \frac{7}{6}$ . Now we make $\frac{7}{6}$ a mixed number: $\frac{7}{6}=1 \frac{1}{6}$ . Therefore, your answer is $\boxed{\boxed{1 \frac{1}{6}}}$ . Hoped I helped. :)

An object was launched off the top of a building. The function f(x)=-16x^2+16x+672 represents the height of the object above the

Katarina [22]

Answer:

6x2 + 16x = 672

Reorder the terms:

16x + 16x2 = 672

Solving

16x + 16x2 = 672

Solving for variable 'x'.

Reorder the terms:

-672 + 16x + 16x2 = 672 + -672

Combine like terms: 672 + -672 = 0

-672 + 16x + 16x2 = 0

Factor out the Greatest Common Factor (GCF), '16'.

16(-42 + x + x2) = 0

Factor a trinomial.

16((-7 + -1x)(6 + -1x)) = 0

Ignore the factor 16.

Subproblem 1

Set the factor '(-7 + -1x)' equal to zero and attempt to solve:

Simplifying

-7 + -1x = 0

Solving

-7 + -1x = 0

Move all terms containing x to the left, all other terms to the right.

Add '7' to each side of the equation.

-7 + 7 + -1x = 0 + 7

Combine like terms: -7 + 7 = 0

0 + -1x = 0 + 7

-1x = 0 + 7

Combine like terms: 0 + 7 = 7

-1x = 7

Divide each side by '-1'.

x = -7

Simplifying

x = -7

Subproblem 2

Set the factor '(6 + -1x)' equal to zero and attempt to solve:

Simplifying

6 + -1x = 0

Solving

6 + -1x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + -1x = 0 + -6

Combine like terms: 6 + -6 = 0

0 + -1x = 0 + -6

-1x = 0 + -6

Combine like terms: 0 + -6 = -6

-1x = -6

Divide each side by '-1'.

x = 6

Simplifying

x = 6

Solution

x = {-7, 6}

Citrus2011 [14]

2.9% apr

5 years to pay

loan= 21450-16450= $5000

apr = .029

.029/12 =.0024

.0024(5000)=12.08

.0024+1=1.0024

1.0024^(5*12)= 1.15

1/1.15= .86

1-.86 = .14
