What’s the x and y intercept of 8x+5y=-48

Mathematics

Anuta_ua [19.1K]4 years ago
4 0

Step-by-step explanation:

8x + 5y =  - 48 \\  \\ at \: x = 0 \\  \\ 8 \times 0 + 5y =  - 48 \\  \\  \therefore \: 5y  = - 48 \\  \\  \therefore \: y  =  \frac{ - 48}{5}  \\  \\ \therefore \: y  - intercept =   - 9.6 \\  \\ at \: y = 0 \\  \\ 8 x + 5 \times 0 =  - 48 \\  \\  \therefore \:8x  = - 48 \\  \\  \therefore \: x  =  \frac{ - 48}{8}  \\  \\ \therefore \: x - intercept =   -6 \\  \\

Which quadrilaterals are not squares?<br><br> Choose each correct answer.
ASHA 777 [7]

Answer:

2 and 4.

Step-by-step explanation:

  • 2 is not a square because a trapezoid does have 4 sides, but the sides are not parallel, or congruent. ↓
  • 4 is not a square because similar to the trapezoid, it does have 4 sides, but is not parallel nor congruent. ↓
  • Although some people consider a rectangle a square, it is a square and also is not because it has 2 pairs of parallel sides, instead of all 4 sides being parallel.

Hope it helps!

One sample of n = 10 scores has a mean of M = 8, and a second sample of n = 5 scores has a mean of M = 2. If the two samples are
schepotkina [342]

Answer:

The mean for the combined sample = 6.

Step-by-step explanation:

We have been given that one sample of n = 10 scores has a mean of M = 8.

So the sum of 10 scores for 1st sample will be: 10\times 8=80

We are also told that second sample of n = 5 scores has a mean of M = 2.

So the sum of 5 scores for 2nd sample will be: 5\times 2=10

When the both samples are combined, so total points will be: 80+10=90 and total scores will be 10+5=15.

\text {Mean for the combined sample}=\frac{\text{Total points of both data sets}}{\text{Total scores of both data sets}}

\text {Mean for the combined sample}=\frac{90}{15}

\text {Mean for the combined sample}=6

Therefore, the mean for the combined sample will be 6.

For what values of x does the graph of f have a horizontal tangent? (Use n as your integer variable. Enter your answers as a com
BartSMP [9]
F(x) = x - 2sinx

To find for what values of x graph has tangents we need to differentiate function f(x).
f'(x) = 1-2cosx
Now, if we want to have horizontal tangents we need to make function f'(x) equal to 0 because at minimum or maximum of function f(x) tangent is horizontal.

1-2cosx = 0
cosx = 1/2
x = pi/3 + 2*n*pi      and
x = -pi/3 + 2*n*pi 

Explanation: cosx = 1/2 for both 60° and -60°. If we make one circle cosx will be equal to 1/2 for 420 and 300 degrees. Writing degrees in radians (using pi) we can write formulas above where 2*pi represents one full circle and n is an integer which represents how many circles we made.
