What is the equation of a line (in slope-intercept form) with a slope of -1 and a y
crimeas [40]

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

What we know:

slope: -1

y-intercept: 0.7

Therefore:

m = -1

b = 0.7

Plug the values of <em>m </em>and <em>b </em>in y = mx + b:

y = -1x + 0.7

OR

y = -x + 0.7

OR

y = 0.7 - x

^^^These are all written in slope intercept form but just in different ways

Hope this helped!

There are two numbers. The first number minus the second number is 15. One-third of the sum of the numbers is one quarter of the
disa [49]

Answer:

So the numbers are 12 and -3.

Step-by-step explanation:

In order to solve this problem we will attribute variables to the numbers, the first one will be "x" and the second one will be "y". From the first sentence we know that the subtraction of the two numbers is equal to 15, so we have:

x - y = 15

Then the problem states that one-third of the sum of the number is equal to one quarter of the first number, so we have:

(1/3)*(x+y) = x/4

Since we now have two equations and two variables we can solve for x and y. From the first equation we have:

y = x - 15

Using this expression for the value of y in the second equation:

(1/3)*(x + x - 15) = x/4

(1/3)*(2*x - 15) = x/4

2*x - 15 = 3*x/4

2*x - 3*x/4 = 15

(8*x - 3*x)/4 = 15

5*x/4 = 15

5*x = 60

x = 60/5 = 12

y = x - 15 = 12 - 15 = -3

So the numbers are 12 and -3.

Consider the sky crane descent portion of the landing sequence.
natulia [17]

Answer: The model predicts 75m

Step-by-step explanation:

The model predicts 75m. The earlier estimate was 1.6km (1 mile) and was close to a given point. The model would only be a good predictor during the sky crane phase of landing.
