Jane is studying the rate at which the sale of a particular brand of chocolate has increased over the years. The graph below sho

ws the number of bars sold y, in thousands, after x years since the year 2000:graph of y equals 15 multiplied by 1.1 to the power of x
What does the y-intercept of the graph represent?

The y-intercept represents the number of bars sold in the year 2000. In this case y=15 because:

y=15(1.1)^0

y=15(1)

y=15

And y is in thousands so this represents the sale of 15000 bars in the year 2000.

The y-intercept, in this case, represents when x is at 0, or when she just began observing.

A man walks for x hours at a speed of

alexandr1967 [171]

Given:

A man walks for x hours at a speed of (x + 1) km/h and cycles for (x - 1) hours at a speed of (2x + 5) km/h.

Total distance travelled is 90 km.

To find:

The value of x.

Solution:

We know that,

$Speed=\dfrac{Distance}{Time}$

$Speed\times Time=Distance$

A man walks for x hours at a speed of (x + 1) km/h, so walking distance is

$D_1=(x+1)(x)$ km

The man cycles for (x - 1) hours at a speed of (2x + 5) km/h, so the cycling distance is

$D_2=(2x+5)(x-1)$ km

Now,

Total distance = 90 km

$D_1+D_2=90$

$(x+1)x+(2x+5)(x-1)=90$

$x^2+x+2x^2-2x+5x-5-90=0$

$3x^2+4x-95=0$

$3x^2+19x-15x-95=0$

$x(3x+19)-5(3x+19)=0$

$(3x+19)(x-5)=0$

$3x+19=0\text{ and }x-5=0$

$x=\dfrac{-19}{3}\text{ and }x=5$

Time cannot be negative. So, the only possible value of x is 5.

Use the substitution method to solve each linear system. 4x - 3y = -13,-2x + y = 4

Contact [7]

Answer:

The solutions to the system of equations are:

$x=\frac{1}{2},\:y=5$

Step-by-step explanation:

Given the system of the equations

$\begin{bmatrix}4x-3y=-13\\ -2x+y=4\end{bmatrix}$

Isolate x for for 4x-3y=-13

$4x-3y=-13$

$4x=-13+3y$

Divide both sides by 4

$x=\frac{-13+3y}{4}$

substitute y=5

$x=\frac{-13+3\cdot \:5}{4}$

$x=\frac{1}{2}$

The solutions to the system of equations are:

$x=\frac{1}{2},\:y=5$

please help now it kinda important i get it done soon or i cant go to a dance for my school tomorrow. im begging u ill give u 5

Answer: 352496

Step-by-step explanation:

First, to find 20% of 440,620, you can multiply:

0.2 x 440,620 = 88,124

Then, to find the new weight of the ship, you can subtract the 20% that was just found (88,124) from the ship's original weight (440,620) to get:

440,620 - 88,124 = 352,496

Therefore, the ship's weight is now 352496.

I hope this helps!

Why couldn't you use synthetic division for the following problern? Make sure to explain fully.

yawa3891 [41]

Because x²+1 has an imaginary solution so you can’t find a value to put on the side for synthetic division
