Answer:

See below

Step.-by-step explanation:

Choice A has first term -3 and common difference 5. The formula for the kth term is -3 + (k - 1)5. It is an arithmetic series.

The required expanded form for the Sum is:

S5 = ∑ [-3 + (k - )5)]

k = 1

Answer:

Expanded form of the series is:

A. -3 + 2 + 7 + 12 + 17

Step-by-step explanation:

when k=1 -3+(k-1)5= -3

when k=2 -3+(k-1)5= -3+5=2

when k=3 -3+(k-1)5= -3+10=7

when k=4 -3+(k-1)5= -3+15=12

when k=5 -3+(k-1)5= -3+20=17

Hence, value of $S_{5}= -3+2+7+12+17$

Hence, expanded form of the series is:

A. -3 + 2 + 7 + 12 + 17

5. How many solutions does this system of equations have?

Diano4ka-milaya [45]

Answer:

$\text{\boxed{\sf{D. \ No\ solution}}}$

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

First, you have to substitute of y=-4x-1.

$\Longrightarrow: \sf{[-4x-1=-4x-9]}$

Add by 4x from both sides.

$\Longrightarrow: \sf{-4x-1+4x=-4x-9+4x}$

Solve.

$\Rightarrow:\sf{-1=-9}\\\\\Rightarrow: \sf{(-9)-(-1)=-9+1=-8}\\\\\Rightarrow: \sf{8=0}$

Therefore, the correct answer is "D. No solution".

I hope this helps. Let me know if you have any questions.

Kelly needs to order lunch for the 6 people at a business meeting. Her menu choices are chicken salad for acost of $5 per person

Lady bird [3.3K]

Hello There!! (:
I'm Here to help!
If we say Kelly orders 1 chicken salad, then it means she ordered 5 egg salads. If she ordered x chicken salads, then she'll have to order the rest, which is (6−x) egg salads. For first equation, let's set y to be the meal's price. It consist of the price of all chicken salads ordered and the price of all egg salads ordered: y=5x+4(6−x) Again, x represents number of chicken salads ordered, and y represents the meal's price. A second equation would come to limit the price to the money Kelly has: y≤28
 Notice there are more constraints to add on the values (x cannot be negative, no such thing negative number of salads or fractional number of salads) so just keep that in mind. Now, since we know the price based on the number of chicken salads, we can say for what number of salads it matches the second restriction: 5x+4(6−x)≤285x+24−4x≤28x≤28−24x≤4

Does this help you?
I Sure hope so have a goodnight ! (:

The domain for f(x) and g(x) is the set of all real numbers.

Rufina [12.5K]

If you want to multiply the two functions, the answer is a.

In fact, you have

$(3x + 5)x^2 = 3x \cdot x^2 + 5\cdot x^2 = 3x^3 +5x^2$
