Answer:

y = 3x + 1

Step-by-step explanation:

it appears the line is crossing the y-axis at 1 so this eliminates the first and third option

the last option is incorrect because '3x²' would not create a straight line

this leaves y = 3x + 1 which means the line crosses the y-axis at one and the slope is 3

Solve 7.8e^((x/3)ln(5))=14. What are the exact and approximate solutions?

Dimas [21]

$\bold{\text{Answer}:\quad x=3\bigg(\dfrac{ln\frac{14}{7.8}}{ln(5)}\bigg)=1.09}$

<u>Step-by-step explanation:</u>

$7.8e^{\frac{x}{3}\cdot ln(5)}=14\\\\\\e^{\frac{x}{3}\cdot ln(5)}=\dfrac{14}{7.8}\\\\\\ln\bigg(e^{\frac{x}{3}\cdot ln(5)}\bigg)=ln\bigg(\dfrac{14}{7.8}\bigg)\\\\\\\frac{x}{3}}\cdot ln(5)=ln\bigg(\dfrac{14}{7.8}\bigg)\\\\\\\large\boxed{x=3\bigg(\dfrac{ln\frac{14}{7.8}}{ln(5)}\bigg)}\\$

x ≈ 1.09

Given triangle ABC with vertices A(16,0), B(9,2), and C(2,0).

Margaret [11]

Given:

Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)

Required:

Side with slope -2/7

Solution:

To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:

m = (y2-y1)/(x2-x1)

We first try points A and B.

m1 = (2-0)/(9-16)

m1 = -2/7

Thus, the side with the slope -2/7 is side AB.

I NEEEEEED HEEEEEEEP PLZZZZZZZZ

Tema [17]

So, since the student makes $30 each week, we can disregard the number of hours.

So, we can model this situation by the following equation

9.5h+30

So, if he works 10.25 hrs (15 minutes = .25 of 1 hr) we just plug that number in

$9.5h+30\\9.5(10.25)+30\\127.275$

Since it's money we round to the nearest cent

So he will make $127.28 Next week
