Answer:

Step-by-step explanation:

11.

f(-8) = (-3/2)(-8) +11 = (24/2) +11 = 12+11 = 23

12.

g(-2) substitute x by -2 in the g( x) equation

9(-2) = (-2)²-7(-2) = 4 +14 = 18

13.

h(2/3) = | 15 -9(2/3)| = | 15 -(18/3)| = | 15 -6 | = |9| = 9

12.

the zero is at x= -2 because is the intersection of the graph with the x-axis

13.

the zero are at x=1, x= -2, x= -4 because is the intersection of the graph with the x-axis

Answer:15/20 3/4

Step-by-step explanation:

Because 3 times 5 =15 and 4 times 5= 20 so that will be 15/20

Then if you multiply 3 and 4 by 1 it will give you 3/4

Answer:

15/20 3/4

Step-by-step explanation:

Answer:

A. x = 3, y = 2

Step-by-step explanation:

The hypotenuse and the length of one leg of one right triangle must be equal to the hypotenuse and corresponding length of the one leg of the other ∆ for both triangles to be equal by the HL Congruence Theorem.

Thus, let's find x and y by setting the corresponding lengths of the two right ∆s equal to each other.

Therefore:

x = y + 1 ----› eqn. 1

2x + 3 = 3y + 3 ----› eqn. 2

Substitute x = (y + 1) into eqn. 2, and solve for y.

2x + 3 = 3y + 3 ----› eqn. 2

2(y + 1) + 3 = 3y + 3

2y + 2 + 3 = 3y + 3

2y + 5 = 3y + 3

Collect like terms

2y - 3y = -5 + 3

-y = -2

Divide both sides by -1

y = 2

Substitute y = 2 into eqn. 1.

x = y + 1 ----› eqn. 1

x = 2 + 1

x = 3

Answer:

Step-by-step explanation:

3x + 4 = - 11

3x = - 11 - 4

3x = - 15

x = - 15/3

x = - 5

Answer:

x = -5

Step-by-step explanation:

3x + 4 = -11

Isolate 3x.

3x = -11 - 4

Evaluate.

3x = -15

Find x.

x = -15 ÷ 3

x = -5

Answer:

The answer is 3⁴ or 81 :)

Answer:

yes

Step-by-step explanation:

I'm not entirely sure what your question is, but x is directly proportional to y, meaning as as x increases at a constant rate, y also increases at a constant rate.

Answer:

The degree of the polynomial is 5

Step-by-step explanation:

When we talk of the degree of a polynomial, we refer to the highest power

The highest power here is 4 but that is not the degree in this case

If we notice, there are two different variables attached to the number

One has a degree of 4 and the other has a degree of 1

What we do here is to add these degrees together

The addition of both is 5 and that is the degree of the polynomial

122 tickets were sold for adults and the rest is for children.

Step-by-step explanation:

Answer: 1550

Step-by-step explanation:

Number of people to see the movie = 12400

Number of comedies = 2

Number of musical = 1

Number of action films = 5

The number of people that'll be be expected to choose a musical during an evening showtime will be:

= 1/8 × 12400

= 1550

Answer:

25 metres per second

Step-by-step explanation:

just divide 100 by 4 and you will get the answer.☺️☺️

Answer:

25 m/s

Step-by-step explanation:

train a travels at 12.5 m/s and will arrive at 100m in 7s.

train b arrives at the same distance, 100m, in 4s. so that means train b is going at 100m/4s and then simplify that

therefore train b is moving at 25m/s

Answer:

No solutions

Step-by-step explanation:

In this question, you would be solving for x.

Solve:

5 + 2(3 + 2x) = x + 3(x + 1)

Use the distributive property.

5 + 6 + 4x = x + 3x + 3

Combine like terms.

11 + 4x = 4x + 3

Subtract 4x from both sides.

11 = 3

Since we don't have an "x value", there are no solutions.

"No solutions" would be your answer.

Answer:

x=53/9

Step-by-step explanation:

(x-2):5=7:9

9x-18=35

9x=35+18

9x=53

x=53/9

Answer:

x = -19/6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

2x + 10 = -4x - 9

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 11/3 does indeed equal 11/3.

∴ x = -19/6 is the solution to the equation.

As C is the mid-point of BD.

Therefore, BC=DC ...(i)

As AB ⊥ BD and ED ⊥ BD

So, ∠ABC= 90° and ∠EDC= 90°

Therefore, ∠ABC=∠EDC= 90° ...(ii)

As two line segments, AE and BD intersect at point C, so the vertically opposite angles are equal.

Therefore, ∠BCA=∠DCE ...(iii)

Now, in ΔABC and ΔEDC,

Angle, ∠BCA=∠DCE [ from equation (iii)]

Side, BC=DC [ from equation (i)]

Angle, ∠ABC=∠EDC [ from equation (ii)]

So, by ASA property of congruency, ΔABC and ΔEDC are congruent

Hence, ΔABC ≅ ΔEDC.

Answer:

Step-by-step explanation:

let

x = price of a sweatshirt

y = trice of sweatpants

three sweatshirts and two pairs of sweatpants for $85.50

3x + 2y = 85.50

three more sweatshirts and four more pairs of sweatpants for $123

3x + 4y = 123

by solving the system of equations

3x + 2y = 85.50

3x + 4y = 123

we find

x = $16

y = $18.75

Answer:

16
