17. Given f(x) = 3x - 1, find f(2)

Step-by-step explanation:

3(2-x)=9

this is the answer to the statement

The expression three times the quantity two decreased by x is nine is - 1

A quantity two decreased by x can be expressed thus :

Multiplying the quantity by 3 :

The expression can be written Mathematically as thus : 3(2 - x) = 9

The expression can be expanded further as :

3(2 - x) = 9

6 - 3x = 9

Collect like terms

-3x = 9 - 6

-3x = 3

x = (3 ÷ -3)

x = - 1

Therefore, the expression equates to - 1

I have explained the solution on paper step by step! but I am typing this to get the solution. to 20 characters

Answer:

20

Step-by-step explanation:

For the area of a rectangle we use A = L* W

We know area or A = 420

and we know length or L = 21

Now we need to find the width or W

(420) = (21) * W

Divide both sides of the equation by 21 to isolate the variable.

That leaves us with:

W = 20

Answer:

160 degrees

Step-by-step explanation:

starting with the 110 degrees angle. the unnamed angle to the right of the 110 degrees is simply the complement of 110 to 180 degrees = 70 degrees.

then B is actually 180 - 90 - 70 = 20 degrees

and then A is the complementary angle of these 20 degrees to 180 degrees = 160 degrees.

Step-by-step explanation:

Given line y=1/3x-4

slope of given line m=1/3

Slope of required line :

m=1/3

As lines are parallel then slope of lines are equal.

Using point slope form:

y-y1=m(x-x1)

p(x1,y1)=(9,8)

y-8=1/3(x-9)

3y-24=x-9

x-3y-9+24=0

x-3y+15=0

Answer:

15 is the middle number

Step-by-step explanation:

BECAUSE IF YOU COUNT FROM THE LEFT AND RIGHT AND WHICH NUMBER APPEARS IN THE MIDDLE IS YOUR MEDIAN

Answer:

15

Step-by-step explanation:

this asks for the median, and not the mean value.

please notice that these 2 values are often if not mostly different from each other.

the median just defines the middle of the value interval, so that half of the different values are left, and half are right of that median value.

here we have 7 values. do we find one, so that 3 other values are smaller, and 3 other values are bigger than that ?

that is 15.

10, 12, 13 are smaller.

16, 19 and 25 are bigger.

so, 15 is the median.

The angle at which the leaning tower of Pisa deviates from the vertical is approximately 5.31 degrees.

To find the angle at which the leaning tower of Pisa deviates from the vertical, we can use the concept of tangent function.

First, we need to calculate the distance that the top of the tower is displaced from the vertical axis. This can be done using the Pythagorean theorem, which states that the displacement (d) is equal to the square root of the height of the tower (h) squared plus the amount the tower is out of plumb (p) squared:

d = √(h² + p²)

d = √(179² + 16.5²)

d = 180.14 ft

Next, we can use the tangent function to find the angle of deviation (θ):

tan(θ) = p/h

tan(θ) = 16.5/179

θ = tan⁻¹(16.5/179)

θ ≈ 5.31 degrees

Answer:

  89.0

Step-by-step explanation:

One way to round a number is to add half the place value you're rounding to, then truncate at the desired place value.

Here, we want to round to a tenth (0.1), so we first add half that value:

  88.98 + 0.05 = 89.03

Now, we throw away all digits after the tenths place.

Answer:

  a2 = 12

  a3 = 36

Step-by-step explanation:

Terms of a geometric sequence have a common ratio. If we call that ratio r, then we have ...

  a2 = 4r

  a3 = (a2)r = 4r^2

  108 = (a3)r = 4r^3

  27 = r^3 . . . . . . . . . . . divide by 4

Answer:

I do this program too, do you have any apps/websites that help with this program??

Step-by-step explanation:

Answer:

Started 100% = x pounds

30% = 75 pounds

x= 75*100÷30= 250 pounds

Starting Weight = 250 pounds

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

30% = 75 pounds

100% = 250 pounds

The starting weight was 250 pounds.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

30% decrease = 75 pounds

Starting weight = 100%

Now,

30% = 75

Multiply 100/30 on both sides.

100/30 x 30% = 100/30 x 75 pounds

100% = 10/3x 75 pounds

100% = 10 x 25 pounds

100% = 250 pounds

Thus,

The starting weight was 250 pounds.

Answer:

Restaurant A and C: 23 grams of fat

Restaurant B: 31 grams of fat

Answer:

Restaurant A's chicken salad has  7.7 grams of fat.

Restaurant​ B's chicken salad has  61.6 grams of fat.

Restaurant​ C's chicken salad has  7.7 grams of fat.

Step-by-step explanation:

Restaurant A = C

Restaurant B = 8 × Restaurant A

Total Grams of Salad = 77

Let Reataurat A and C be x

and Reataurant B be 8x

so

A + B + C = 77

x + 8x + x = 77

2x + 8x = 77

10x = 77

x = 77 ÷ 10

x = 7.7

Restaurant A's chicken salad has  7.7 grams of fat.

Restaurant​ B's chicken salad has  61.6 grams of fat.

Restaurant​ C's chicken salad has  7.7 grams of fat.

Because her spending exceeds her monthly income, Jenna needs a budget to avoid spending money she does not have.

Step-by-step explanation:

Jenna need a budget because her monthly income are less than the spending amount.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Jenna’s monthly monetary income is $1,200.

And, Her total spending last month was $1,400.

Here, We have;

⇒ 1200 < 1400

Thus, Jenna need a budget because her monthly income are less than the spending amount.

Therefore, Jenna need a budget because her monthly income are less than the spending amount.
