Evaluate the following expression:42/12 - 85/25 + 117/30

Answers

Answer 1

Answer:

4

Step-by-step explanation:

Let's first simplify all terms, then convert them to /10:

42/12 = 7/2 = 35/10

85/25 = 17/5 = 34/10

117/30 = 39/10

Then the final addition is:

(35-34+39)/10 = 40/10 = 4

Answers

Answer:

f(-1) = -8

f(1) = -12

Step-by-step explanation:

-1 and 1 are inputs to the function f which is shown on the graph.

The inputs are on the x-axis so when x = -1, the graph shows that the function f at -1 is approximately -8.

When x = 1, the function f is approximately -12.

2. Use the distributive property to evaluate the expression.
A) 4(x-2)
B) 3(y+9)
C) -2(3-r)

Answers

Answer:

a) 4x-8

b) 3y + 27

c) -6 + 2r

Step-by-step explanation:

Here, we want to use the distributive property to evaluate the given expressions

Mathematically, the distributive property is;

(a + b) * c = (a * c) + (b * c)

So we use this on each of our questions;

a) 4(x-2)

= (4 * x) - (4 * 2) = 4x-8

b) 3(y + 9)

= (3 * y) + (3 * 9)

= 3y + 27

c) -2(3-r)

= (-2 * 3) - (-2 * r)

= -6 + 2r

Solve: |11x + 10| = 22

Answers

To solve the equation |11x + 10| = 22, we need to consider two cases: one where the expression inside the absolute value is positive and one where it is negative.

Case 1: (11x + 10) is positive:

In this case, the equation becomes 11x + 10 = 22. Solving for x, we subtract 10 from both sides, resulting in 11x = 12. Dividing by 11 gives x = 12/11.

Case 2: (11x + 10) is negative:

Here, the equation becomes -(11x + 10) = 22. Simplifying, we have -11x - 10 = 22. Adding 10 to both sides gives -11x = 32. Dividing by -11 yields x = -32/11.

Thus, the solution set for the given equation is x = 12/11 and x = -32/11, representing the two possible values of x that satisfy the equation |11x + 10| = 22.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -x + 1

Step 2: Rewrite Systems

y = 4x - 14

Multiply everything by -1:                    -y = -4x + 14

y = -x + 1

-y = -4x + 14

Answers

Answer:

X = -1 or X = -3.5

Step-by-step explanation:

2x^2 + 9x + 7 = 0

ac = 14

b = 9

find a two numbers which when you multiply you get 14 and add you get 9.

so it will 2 and 7. (they replace b which is 9x)

therefore: 2x^2 + 2x + 7x + 7 = 0

find common factors using each 2 from the four.

2x( x + 1) + 7 (x+1) = 0

so it will be (2x + 7) (x+1) = 0

find x,

i) 2x +7 = 0

x= -3.5

ii) x + 1 = 0

x = -1
