The x-intercept of a line is when the y coordinate is equal to 0. So, the x-intercept would be (0,-7).
The y-intercept of a line is when the x coordinate is equal to 0. So the y-intercept would be (-5,0).
To find the equation of a line, you need the slope and the y-intercept.
We already know the y intercept is -5. The equation for a line is:
Y=mx+b
m stands for slope
b stands for the y intercept.
To find the slope, use the equation-
y1-y2
--------
x1-x2
Another way to say that is the change in y over the change in x.
Plug in the the 2 coordinate points you know, which are (-7,0) and (0,-5).
0+5
-------,
-7-0
5/-7.
The slope is 5/-7
The Y intercept is -5
The equation of the line is y= 5/-7x -5
The coordinate point for the x intercept is (-7,0)
The coordinate point for the y intercept is (0,-5)
C. Fernando incorrectly found the product of -2 and -5

Answer:
The answer is 1800.
Step-by-step explanation:
3/540 = 10/x
3x = 540 × 10
x = 5400/3
x = 1800
Answer:
the submarine is 92.994 feet ≈ 93 feet deep from the surface of the water
Step-by-step explanation:
We can think in a triangle where the hypotenuse is the detection distance and the angle with the horizontal surface of water is the depression angle, then the underwater distance is the vertical side of the triangle.
If we denote Ф as the angle of depression ,d as the detection distance and x as the unknown depth of the submarine, using trigonometry:
x = d* sin Ф
thus
x= d * sin Ф = 238 feet * sin 23° = 92.994 feet ≈ 93 feet
Here is the complete question
A nominal interest rate of 5%
A real interest rate of 5%
A real interest rate of 3%
A nominal interest rate of 3%
Answer:
A real interest rate of 5%
Step-by-step explanation:
A real interest rate of 5% is the best option for oscar. The nominal rate of interest is a type of interest rate that shows the increase in in percentage of money without the depreciation discount that is usually caused by inflation or the payment of tax.
The real rate of interest shows the real increase in the money that has been paid for an investment. This is after inflation has been discounted and all forms of taxes have been paid.
So oscar should invest his $4000 on a savings account whose real interest rate is 5% per year
