Answers

Answer 1

Answer:

12

Step-by-step explanation:

[tex] {x}^{2} - 3x + 8[/tex]

(Putting value of x = 4)

[tex] = {4}^{2} - 3 \times 4 + 8[/tex]

= 16 - 12 + 8

= 24 - 12

= 12 (Ans)

Answer 2

Answer:

It is 12

Step-by-step explanation:

[tex]f(x) = {x}^{2} - 3x + 8[/tex]

When x is 4, substitute x as 4:

[tex]f(4) = {(4)}^{2} - 3(4) + 8 \\f(4) = 16 - 12 + 8 \\ f(4)= 12[/tex]

Which One Does Not Belong? EXPLAIN your REASONING

Answers

Answer:

The last one

Step-by-step explanation:

0.3333..., 30%, 3/10 are parts.

The last one ( 3 circles) are 3 wholes.

(whole numbers)

I hope this helped:)...

:-)

Hey there! I'm happy to help!

30% is the same thing as 0.3, which is 30% of 1.

0.3 is what you multiply numbers if you want to see what 30% of that number is as 0.3 is 30% of 1, the whole number.

3/10 is the same value as 30% because 3 divided by 10 is equal to 0.3, which is 30%.

The dots in the boxes are also the same thing as 3/10. There are 10 boxes, and 3 out of the 10 have dots, which is 3/10 and 30%.

The one that does not belong is 0.333333...... This is equivalent to 1/3, which is greater than 30%, 0.3, and 3/10.

Find three consecutive even integers so that twice the largest
is 20 less than the sum of all three

Answers

If x is the smallest of the three, then the next two integers are x + 2 and x + 4.

"Twice the largest is 20 less than the sum of all three" translates to

2 (x + 4) = (x + (x + 4) + (x + 6)) - 20

Solve for x :

2x + 8 = 3x - 10

x = 18

Then the three numbers are {18, 20, 22}.

Answer:look below

Step-by-step explanation:Let x, x+2 & x+4 be the 3 integers.

x+2(x+2)=(x+4)+20

x+2x+4=x+4+20

3x+4=x+24

3x-x=24-4

2x=20

Gina rented a truck for one day there was a base fee of 1275 there was an additional charge of 20 cents for each mile driven the total cost c in dollars for driving in miles is given by the following function

Answers

Answer:

[tex]1275+0.2m=c[/tex]

m is the amount of miles driven, c is the total cost.

Step-by-step explanation:

Since she has a flat fee of 1275, that's the 1275 in the equation and since we don't know how many miles she drives, that's the m in the equation for miles driven. Since each mile costs 0.20, that's the 0.2 in the equation. And since c is the total cost in dollars, that's the c in the equation.

8. The difference of thirty-one and seventeen
divided by the product of ten and four

Answers

Answer:

[tex]\frac{7}{20}[/tex]

Step-by-step explanation:

The difference 31 - 17 = 14

The product 10 × 4 = 40

Then

[tex]\frac{14}{40}[/tex] = [tex]\frac{7}{20}[/tex] ← in simplest form

The difference between thirty-one and seventeen divided by the product of ten and four will be 7 / 20.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The difference between thirty-one and seventeen will be expressed as,

⇒ 31 - 17

⇒ 14

The product of ten and four will be expressed as,

⇒ 10 x 4

⇒ 40

Then the difference between thirty-one and seventeen divided by the product of ten and four will be expressed as,

⇒ 14 / 40

⇒ 7 / 20

Thus, the difference between thirty-one and seventeen divided by the product of ten and four will be 7 / 20.

Step-by-step explanation:

This uses the sine law.

Sin(theta)/113 = sin(42)/120             Multiply both sides by 113

sin(theta) = 113*sin(42)/120

sin42 = 0.6691

sin(theta) = 113 * 0.6691 / 120

sin(theta) = 0.630008

theta = sin-1(0.63008)

Step-by-step explanation:

Vertically translate f(x) two units down by subtracting 2 from f(x).

f(x) = |4x + 3| + 2

To translate 2 units down, subtract 2

f(x) = |4x + 3| + 2 - 2
