Charles buys 10 drinks and 3 sandwiches for $34. Isabel buys 5 drinks and 4
sandwiches for $37. They want to determine the cost of each item.
Write a system of linear equations to model the problem. Let d equal the cost
of each drink and let s equal the cost of each sandwich. Solve the system
algebraically. How much does each item cost?

Answer:

-1

Step-by-step explanation:

We can plug in -3 for x and solve:

f(-3) = -3 + 2

= -1

Answer:

P(x) = x² - 15x + 50

Step-by-step explanation:

We write the polynomial function P(x), given that P(x) = 0 has the given roots, x = 5 and x = 10.

Since x = 5 and x = 10 are the roots of P(x) = 0, it follows that (x - 5) and (x - 10) are factors of P(x) = 0. So, P(x) = (x -5)(x - 10) = 0

Expanding the brackets, we have

x² - 10x - 5x + 50 = 0

Simplifying, we have

x² - 15x + 50 = 0 = P(x)

Thus,

P(x) = x² - 15x + 50

Answer:

Yes.

Answer:

1.)x=15.9

2.)x=17.49

3.) x=7.29

Step-by-step explanation:

For all the questions use Pythagorean Theorem which is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]

C=opposite of hypotenuse

A=Leg

B=Leg

1.) [tex]6^{2}[/tex]+[tex]b^{2}[/tex]=[tex]17^{2}[/tex]

Simplify the equation

36+[tex]b^{2}[/tex]= 289

Subtract 36 from both sides

[tex]b^{2}[/tex]=289

Square Root both sides to equal 15.9

Do the same for questions 2-3

Hope this helps! :)

Answer:

B' has a coordinate pair of (-4, -1)

Step-by-step explanation:

We are given with the vertices of the triangle with B(-8,-2)

Please remember the rule of dilation

If a point (x,y) dilated for the scale factor of 'k', we do get image as (kx,ky)

Using this concept, we know scale factor is [tex]\frac{1}{2}[/tex] , we could get image as [tex](\frac{1}{2} (-8), \frac{1}{2} (-2))[/tex]

Let's simplify it

We do get (-4,-1)

Answer:

Boba Club is cheaper if you want to buy 7 Boba drinks. It's cheaper by 3.

Step-by-step explanation:

Boba Club: y=2x+4

Jack's Boba: y=3x

Replace the X variable with 7 for both equations. For Boba Club, multiply 2 by seven to get 14, then add four to get 18. For Jack's Boba, multiply 3 and 7 to get 21. Boba Club is cheaper. (What would you need 7 Boba drinks for though?)

Answer:

Boba Club is cheaper if you want to buy 7 Boba drinks. It's cheaper by 3.

Answer:

Step-by-step explanation:

j represents the amount of juice

2 : 3 :: j : 18        proportion

3j = (2)(18)

Step-by-step explanation:

o2+a2=h2

100} h^{2}=(10ft)^{2} +(17ft)^{2}

h2=100ft2+289ft2

h=389ft2−−−−−√

→19.7ft

this is an example on how to do it

The value of g in the given right triangle is 13.20 units.

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Given that, a right triangle with leg lengths f and g, and hypotenuse h, if f = 7 cm and h = 11.2 cm,

We need to find the value of g the hypotenuse,

So, here using the Pythagoras theorem,

f²+h² = g²

Therefore,

11.2²+7² = g²

g² = 174.44

g = 13.20

Hence, the value of g in the given right triangle is 13.20 units.

Answer:

7.5 years.

Step-by-step explanation:

Use A = 1400(1+0.02)^7.5

The 1400 is the starting money. The 1 is a constant. The 0.02 is the 2% in decimal form. And the 7.5 is years. I found that by just continually increasing it until it hit 1624.
