f(x) = -12x + 5. Find f(-3).​

Answer:

1 3/20

Step-by-step explanation:

1. Make them all into fractions:

-8/4 -1/4 -(-15/5 -2/5)

2. Add like-terms:

-9/4 -(-17/5)

3. A negative times a negative makes a positive:

-9/4 +17/5

4. Identify the least common denominator (LCD):

20

5. Apply:

-9x5/4x5 +17x4x/5x4

6. Solve:

-45/20 +68/20

7. Result:

23/20, simplified 1 3/20

Answer:

DeMonte is 12

Step-by-step explanation:

If Micah is not yet 15 than he is 14 so 14 - 2 is 12 since DeMonte is two years younger than Micah.

Answer:

Step-by-step explanation:

x2 - 49

Both are squares so

Square root (x2) - Square root (49)

= x - 7

The other two answers are x - 3 and x - 4

Answer:

Use the formula (x-a)(x+a)=x^2 - a^2

so what is the square root of 49, 9, and 16? By finding the square root you get a, and you can just plug it into the formula. For example the first one, 7 is the square root of 49. So, (x-7)(x+7)

Answer:

884

Step-by-step explanation:

We know the ratio of A to B is 5:8

let x = the multiplier

then

5x = amt of compound A

and

8x = amt of compound B

:

5x + 8x = 884

13x = 884

x = 884/13

x = 68 is the multiplier

therefore

5(68) = 340 millilters of compound A needed

:

:

Confirm our answer. Find the amt of B

8(68) = 544 ml of B

340 + 544 = 884

Answer:

Give me that crown again

Answer:

22, 19, 16, 10

Step-by-step explanation:

y = 25-(3*1)= 22

y = 25-(3*2)= 19

y = 25-(3*3)= 16

y = 25-(3*5)= 10

Answer:

8

Step-by-step explanation:

Arrange the set of numbers from least to greatest:

3,6,6,6,8,9,16,16,18

Start from both ends and cross them off until you're left with just one.

6,6,6,8,9,16,16

6,6,8,9,16

6,8,9

8

The median is 8 because that's what you're left with.

Answer:

Emmas father would be 40 years old

Step-by-step explanation:

if the father is 40 years old right now emma will be his age in 30 years.

in 30 years emma will be as old as he was when she was ten (10+30=40)

after the 30 years emmas father who was once 40 years when she asked how old he was would be 70 years old (30+40=70)

He is 40 years old.

Equation: (f+e)/2 = father's age. Here f=70 and e=10.

So, (70+10)/2 = 80/2 = 40.

Solution can be wrong. But answer is right. Answer is definitely 40 years old

Since you know a line is = 180*

if angle EFG is 125, we can get angle EFD = to 180-125=55

And since we know that the line ED is congruent to line EF, angle EDF is = 55

180-55*2= 70

angle DEF=70

Answer:

70° and 110°

Step-by-step explanation:

Supplementary angles sum to 180°

sum the parts of the ratio, 7 + 11 = 18 parts

Divide 180° by 18 to find the value of one part of the ratio.

180° ÷ 18 = 10° ← value of 1 part, thus

7 parts = 7 × 10° = 70°

11 parts = 11 × 10° = 110°

The 2 angles are 70° and 110°

Answer:

The value of x is 16

Step-by-step explanation:

Given two angles are:

(4x + 19) and (7x -29)°

Two angles being congruent means that their numerical values will be equal

Putting both expressions equal

[tex]4x+19 = 7x-29[/tex]

Subtracting 7x from both sides

[tex]4x+19-7x = 7x-29-7x\\-3x+19 = -29[/tex]

subtracting 19 from both sides

[tex]-3x+19-19 = -29-19\\-3x = -48[/tex]

Dividing both sides by -3

[tex]\frac{-3x}{-3} = \frac{-48}{-3}\\x = 16[/tex]

Hence,

The value of x is 16

Answer:

The approximate diameter of the larger tank is 8.10 meters

Step-by-step explanation:

Here, we want to calculate the diameter of the larger tank

The volume of a sphere

V = 4/3 * π * r^3

Let us calculate the volume of the standard model

That will be;

Since diameter is 6 and r = d/2

r = 6/2 = 3 meters

V = 4/3 * π * 3^3 = 36 π m^3

Now, the volume of the larger tank is 2.5 times of this;

The volume of the larger tank is 2.5 * 36 π = 90 π m^3

So we can calculate the radius of this before we calculate its diameter

4/3 * π * r^3 = 90 π

4r^3/3 = 90

r^3 = 270/4

r^3 = 67.5

r = 3x√(67.5)

r = 4.07 m

Diameter here is 2 times this

= 4.07 * 2 = 8.14

8.1

Answer:

IT's -3.6 & 14.4 so D is the correct answer

Step-by-step explanation:

x= -3.6 y= 14.4

HOW I SOLVED IT

-3.6 x 3 = -10.8    2 x 14.4 = 28.8 - 10.8 = 18  so correct since it must equal to 18

-2/3 x -3.6 =2.4  + 12 = 14.4 so correct since y = 14.4
