0.3:2=d:8 find d

i'll mark brainliest if you are correct.

Answers

Answer 1

Answer:

1.2

Step-by-step explanation:

0.3/2 = d/8

multiply 0.3 by 4 which is 1.2 because 2 * 4 is 8

Answer 2
D=1.2
to find the answer set up a proportion. Cross multiply to get 2d=2.4* *8x0.3
Then, divide 2.4 by 2 to get d by itself.
2.4/2 = 1.2

Hope this helps :)

A bottlenose dolphin is 10 feet below sea level. Then it begins to dive at a rate of 9 feet per second. What is the equation of the line that represents its elevation, y, after x seconds?
A.
y = 9x − 10
B.
y = -9x − 10
C.
y = 9x + 10
D.
y = -9x + 10

Answers

B is the correct answer

Answer:

B. y=-9x-10

Step-by-step explanation:

The dolphin is starting 10 feet below sea level so the y-intercept (or b in slope-intercept form) would be negative 10. Diving means going down, or a negative slope, so the slope would be -9. When you plug those numbers into y=mx+b, you would get y=-9x-10.

1. How many cars per day does Car Mart sell? How did you use the table to find this rate?
2. How many cars per day does Winston's sell? Explain how you found this rate.
3. Which dealership sells more cars per day? How many more?
4. Which dealership started with more cars? How many more cars did that dealership start with?
Explain how you found your answer.

Answers

1. Car Mart sell 11 cars per day.
You can use the table by looking at day 2 and day 3. You can see underneath it, it shows how many cars is left after that particular day. So from day 2, you have 43 cars left and day 3, you got 32 cars left. From 43 car to 32 car is losing 11 car. So each day the Car Mart sell 11 car.

2. First we know that after 3 days, Winston have 32 cars left and after 5 day, it has 12 cars left.
Here’s the chart that I made for Winston:
Each day, Winston’s sell 10 cars. (Lose 10 cars per day)

1. Car Mart sells 11 cars a day.

2. Winston's sells 10 cars per day.

3. Car Mart sells one more car per day.

4. Winston started with more cars.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Rate for Winston auto dealer is (32 - 12)/(3 - 5) = - 10.

Rate for cart mart is (32 - 43)/(3 - 2) = - 11.

Car Mart sells 11 cars a day.

Winston's sells 10 cars per day.

Car Mart sells more cars per day.

As cart mart has 43 crs left on the second day he must had 10 more cars on the starting day which is 53.

As Winston had 32 cars on the 3rd day it must had (32 + 11 + 11 ) = 54 cars on the started day so Winston started with more cars.

Just like Transformations in Geometry, we can move and resize the graphs of functions. Let us start with a function, in this case it is f(x) = x2, but it could be anything: ... g(x) = x2 + C. Note: to move the ... If you change that to (age+4) = 25 then you will get it when you are 21. Adding 4 ... Example: the function v(x) = x3 - x2 + 4x.

The graph of the function y = 2x⁴ - 5x³ + x² - 2x + 4 is plotted and attached.

What is a polynomial?

Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). For example -

y = 4x⁴ + 3x³ + 2x² + 6x + 7

We have the following polynomial functions -

f(x) = 2ˣ

g(x) = f(x - 3) + 4

We can write g(x) as -

g(x) = 2ˣ ⁻ ³ + 4 = (2ˣ/2³) + 4

g(x) = (2ˣ/8) + 4

The graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards.

Therefore, the graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards to given the function g(x)

b. x + (x + 4) = 52
c. x(x + 4) = 52

Answers

Should be B

Because if it were C or D it would be the product and not the sum
b

if the smaller number is 4 more it can be represented as x+4 and then you add x to the greater number to get 52 which is why the equation is x+(x+4)=52
