The cost of a bag of chips in a vending machine is $0.85. The cost of a Gatorade in the same machine is $1.50. Kennedy spent $23

.70 on chips and Gatorade for her track team, and bought a combination of 21 bag of chips and Gatorade. Which step shows the FIRST mistake in applying the Elimination Method to solve this problem? A) Step1: - 0.85(x + y = 21) 0.85x + 1.50y = 23.70 B) Step 2: - 0.85x + y = 21 0.85x + 1.50y = 23.70 C) Step 3: 2.50y = 44.70 D) Step 4: y = 17.88

A bag of chip  = 0.85, let a bag of chip be x
a bag of gatorade is 1.50, let gatorade be y
23.70 is the amount Kennedy spent in all

0.85x + 1.50y = 23.70
step 1: shows the wrong step already, because you shouldn't take out a -0.85, and y is not 0.85 either, but 1.50, so y should still have 1.76 left

so your answer should be step 1.

hope this helps

Step 1 : -0.85(x + y = 21) <== I have no idea why they r  multiplying -0.85 by that equation

it should be :
x + y = 21
0.85x + 1.50y = 23.70

Samantha is studying the population growth of an endangered birth. The growth can be modeled by the equation B(t) 100 + 3/5t^5 ,
solong [7]

The value of the population of the growth of an endangered birth after 5 years is 1975

<h3>How to determine the population after 5 years?</h3>

The population function is given as:

B(t) = 100 + 3/5t^5

At 5 years, the value of t is 5

So, we have

t = 5

Next, we substitute 5 for t in the equation B(t) = 100 + 3/5t^5

This gives

B(5) = 100 + 3/5 * 5^5

Evaluate the exponent

B(5) = 100 + 3/5 * 3125

Evaluate the product

B(5) = 100 + 1875

Evaluate the sum

B(5) = 1975

Hence, the value of the population of the growth of an endangered birth after 5 years is 1975

#1 #2 #3 &amp; #4 thank you

I only (sort of) know 3 and 4

3. Andle 1 is an example of an angle bigger than
{90}^{o} c
I don't know what you call it.

4. If you have a straight line, both angles (or more) added up need to be
{180}^{o} c
so if angle 1 is 129, 180-129=51
angle 2 is
{51}^{o} c

If 1 is what is the relationship between the two angles, then maybe the answer is that they both added up need to be 180 degress (?)

And 2 is probably the same as 3 but with angle 2, angle two is an example of an angle smaller than 90 degrees

What are the solutions to the nonlinear system of equations below?
Sonbull [250]
Substitute y=4x to the second equation:

x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1

When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4

Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
