Answer:

f(x) and g(x) have the same y-intercept

Step-by-step explanation:

the y-intercept is the point, where the graph intersects the y-axis.

and what is the definition of the y-axis ? it is

x = 0

for all the values up and down the y-axis, their x-coordinate is 0.

so, to find the y-intercept we find the functional value for x = 0.

and that is here in both cases : -32

and the y-intersect point is therefore for both functions:

(0, -32)

Marie, Shelia, and Martha bought snacks for a girl's sleepover. They each bought the items shown in the following table at the l

creativ13 [48]

Using a system of equations, it is found that the unit prices are:

$2.25 for a bag of chips.

$1.50 for a liter of pop.

$1.75 for a chocolate bar.

For the system:

x is the unit price of a bag of chips.

y is the unit price of liter of pop.

z is the unit price for a chocolate bar.

From the table, the equations are:

$2x + 2y + z = 9.25$

$3x + 4y + z = 14.50$

$x + 3y + 3z = 12$

Replacing the first equation on the second and the third:

$z = 9.25 - 2x - 2y$

$3x + 4y + z = 14.50$

$3x + 4y + 9.25 - 2x - 2y = 14.50$

$x + 2y = 5.25$

$x = 5.25 - 2y$

$x + 3y + 3z = 12$

$x + 3y + 3(9.25 - 2x - 2y) = 12$

$-5x - 3y = -15.75$

$5x + 3y = 15.75$

Since $x = 5.25 - 2y$ :

$5(5.25 - 2y) + 3y = 15.75$

$-7y = -10.5$

$y = \frac{10.5}{7}$

$y = 1.5$

Then:

$x = 5.25 - 2y = 5.25 - 2(1.5) = 2.25$

$z = 9.25 - 2x - 2y = 9.25 - 2(2.25) - 2(1.5) = 1.75$

The unit prices are:

$2.25 for a bag of chips.

$1.50 for a liter of pop.

$1.75 for a chocolate bar.

A cake recipe calls for 1 cup of oil. Jean needs to make 12 cakes for her school bake sale. How many quarts of oil will Jean nee

kipiarov [429]

Hey there,

Each cake recipe would call for $\boxed{1}$ cup of oil.

So if she is going to make 12 cakes, this would include that she
would need to use 12 cups of oil.

$\boxed{12}$ would be your answer!

Hope this helps.

31 and 81 are in the bottom corners of the triangle X is at the top . What is X?

kati45 [8]

Answer:

The top angle of the triangle is, X = 68°.

Step-by-step explanation:

Let there is a triangle named PQR with bottom corner angles ∠ P and ∠ Q and the ∠ R is the angle at the top.

Now, given that ∠ P = 31° and ∠ Q = 81° and we have to find out ∠ R i.e. X.

In Δ PQR, we know, ∠ P + ∠ Q + ∠ R = 180°

⇒ 31° + 81° + X = 180°

⇒ X = 68°

Therefore, the top angle of the triangle is 68°. (Answer)

Is (x+1) a factor off (x)=x3+x2−4x−4? A) Yes B) No

satela [25.4K]

Remainder theorem again...

$p(x)=x^3+x^2-4x-4$

$p(-1)=(-1)^3+(-1)^2-4(-1)-4=0$

So Yes, $x+1$ is a factor.
