PLEASE SOMEONE HELP ME ANSWER THIS !!!!

Mathematics
1 answer:
Mumz [18]2 years ago
6 0

Step-by-step explanation:

Part A: Linear Equation.

  • One of the points is (0,15). This means 0,15 is the y intercept so b=15.

We can find the slope

\frac{5 - 15}{1  - 0 }  =  \frac{ - 10}{1}  =  - 10

So our equation is

y =  - 10x + 15

Part B: Exponential Equation

We know that

15 = a \times b {}^{0}

B to the zero power is 1 so

15 = a

This means a =15. Now let find b.

5 = 15 \times b {}^{1}

\frac{1}{3}  = b

So the equation is

y = 15( \frac{1}{3} ) {}^{x}

nalin [4]
Here is your answer

B) 1/125

REASON:

Given,

F (x)={(1/5)}^{x}

for F (3)

Putting x=3, in above function we get

F (3)= {(1/5)}^{3}= 1/125

olga nikolaevna [1]

Answer:

10.54 kg

Step-by-step explanation:

Given that :

Half of blueberries is served with breakfast

The remaining 5270g is served with dinner

How many kilograms of blueberries did the science camp start with :

Total grams of blue berries :

(Grams served at breakfast + grams served at dinner)

Let total blueberries = x

x/2 + 5270 = x

(x + 10540) /2 = x

x + 10540 = 2x

10540 = 2x - x

x = 10540 grams

Amount of kilograms science camp started with = (10540) / 1000 = 10.54 kg

24+0.44x=19+1.69x<br> Can someone answer this real quick
abruzzese [7]

24 + 0.44x = 19 + 1.69x

Subtract 19 from both sides

5 + 0.44x = 1.69x

Subtract 0.44x from both sides

5 = 1.25x

Divide by 1.25 on both sides

4 = x
