A

7*(1)(14) = 98 Not the right answer. I have done what is inside the brackets first. (5 - 4) = 1; (5 + 9)= 14; 7 * 1 * 14 = 98 which is not 6

B

7 * [1 * 5] + 9 = 44; 7 * 5 + 9 = 35 + 9 = 44 Also not 6

C

7*[5 - 20 + 9] = - 42; Not 6 as well 7*[14-20] = 7*-6 = - 42

D

7*5 - [20 + 9] = 35 - 29 = 6

Answer D

B - Bracket O - Order D - Division M - Multiplication A - Addition S - Subtraction

The last option (7 * 5) - [(4 * 5) + 9]

In Order so you do the first bracket

7 * 5 = 35

Then in the second bracket, you see (4 * 5) + 9

Bracket before addition so,

4 * 5 = 20 20 + 9 = 29

35 - 29 = 6

The function f(x) = 1.50x – 30 gives the amount of money Amelia has to spend each week for x school lunches, after taking money
Naya [18.7K]
To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)

So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20

Hope this helps

Chris and his brother leave the same point and run in opposite directions on a straight road. After running for 3 Hours they are
ikadub [295]
<span>Chris' average speed is 3.5mph: Lets take Chris' brother speed = B then Chris speed = (B+ 1) mph-------given in the question and: The average speed for covering 18 miles= chris' average speed + his brother's average speed = (B+ 1) + B since Speed = Distance covered / time taken then average speed for 18 miles can also be found by: 18 miles/3 hours = 6 miles per hour then we have; (B+ 1) + B = 6mph (B +1) = (6-B) B+B = 6-1=5 2B=5 B=5/2=2.5 mph (this is Chris' brother average speed) Hence Chris' average speed is = B+1= 2.5+1= 3.5mph</span>

What is the product?
victus00 [196]

Answer:

\begin{bmatrix}-2\\0 \end{bmatrix}

Step-by-step explanation:

We have the product, 2\times \begin{bmatrix}-1\\0 \end{bmatrix}.

It is known that,

'When we multiply a scalar with a matrix, the scalar is multiplied by each element of the matrix'.

So, we get,

2\times \begin{bmatrix}-1\\0 \end{bmatrix}.

⇒ \begin{bmatrix}-1\times 2\\0\times 2 \end{bmatrix}

⇒ \begin{bmatrix}-2\\0 \end{bmatrix}

So, the resulting product is \begin{bmatrix}-2\\0 \end{bmatrix}.

What is the general equation of a cosine function with an amplitude of 3, a period of 4 pi, and a horizontal shift of negative p
liberstina [14]

The cosine function with the given characteristics is:

f(x) = 3*cos(x/2 - pi).

<h3>How to get the cosine function?</h3>

The general cosine function is:

f(x) = A*cos(kx + p)

Where A is the amplitude and p is the phase, then we know that:

A = 3

p = -pi

Then we have:

f(x) = 3*cos(kx - pi)

And the period is equal to 4pi, then we must have that:

k*(x + 4pi) - pi = k*x - pi + 2pi

k = 1/2

Then the function is:

f(x) = 3*cos(x/2 - pi).

2x + y = 7 y = x + 1 When the expression x+1 is substituted in for y in the first equation, the result is
Charra [1.4K]

2x + y = 7

substitute

2x + (x+1) =7

combine like terms

3x+1 =7

subtract 1 from each side

3x =6

divide by 3

x=2

y = x+1

y =2+1

y=3

Answer: x=2, y=3
