"For which value of k does the system have no real number solutions?"
The answer is 4, because 4+4≠16.

"For which value of k does the system have one real number solution?"
The answer is -0.25, because the linear line because tangent with the parent function.

"For which value of k does the system have two real number solutions?"
The answer is 2, because the linear function intercepts the parent function 2 times.

Answer: 97.7 in

Step-by-step explanation: The perimeter is another name for circumference. Since we know that the formula for circumference is 2(pi)r, but we only want half of that.

Note that 2r is another way of writing the diameter (d).

In this case, we can use the formula d(pi)/2 + d (we’re adding d because d(pi)/2 will only give us the perimeter of the arch.

38(pi)/2 = 59.66

59.66 + 38 = 97.66

Rounded, that would be 97.7 in

How do you divide 50 by 60 and get 85

Ratling [72]

you cannot get that answer.... when you divide. Put the number into a fraction first so, it makes it easier to see what you are doing. So, $\frac{50}{60}$ .Now simplify the cross off the zero from the top and the bottom to get $\frac{5}{6}$ . So, $\frac{5}{6}$ will give you 0.83333333333...3.

Using a system of equation, we have that:

x, which is the cost of on-site service.
y, which is the cost of at-store service.
z, which is the cost of by-mail service.

The system is:

$x = 3y$

$z = y - 10$

$15x + 40y + 5z = 3100$

The cost of one on-site repair service is of $90.

Item a:

The variables are:

x, which is the cost of on-site service.
y, which is the cost of at-store service.
z, which is the cost of by-mail service.

Item b:

On-site service costs 3 times as much as at-store service, thus:

$x = 3y$

By mail service costs $10 less than at-store service, thus:

$z = y - 10$

Last week, the shop completed 15 services on-site, 40 services at-store, and 5 services by mail for total sales of $3100, thus:

$15x + 40y + 5z = 3100$

The system is:

$x = 3y$

$z = y - 10$

$15x + 40y + 5z = 3100$

Item c:

The cost of one on-site repair service is x.
First, replacing the first two equations into the third, we find y, and then with it we find x.

$15x + 40y + 5z = 3100$

$15(4y) + 40y + 5(y - 10) = 3100$

$60y + 40y + 5y = 3150$

$105y = 3150$

$y = \frac{3150}{105}$

$y = 30$

Then

$x = 3y = 3(30) = 90$

The cost of one on-site repair service is of $90.

The florist charges $31.75 for eight roses and five carnations. For one rose and three carnations, it cost $5.75. What is the co

Sedbober [7]

Cost for a carnation is $0.75

Step-by-step explanation:

Let,

Rose = x

Carnation = y

According to given statement;

8x+5y=31.75 Eqn 1

x+3y=5.75 Eqn 2

$Multiplying\ Eqn\ 2\ by\ 8\\8(x+3y=5.75)\\8x+24y=46 \ \ \ Eqn\ 3\\Subtracting\ Eqn\ 1\ from\ Eqn\ 3\\(8x+24y)-(8x+5y)=46-31.75\\8x+24y-8x-5y=14.25\\19y=14.25\\Dividing\ both\ sides\ by\ 19\\\frac{19y}{19}=\frac{14.25}{19}\\y=0.75$

Cost for a carnation is $0.75
