The inequality to find the scores she must make on the final exam to pass the course with an average of 77 or higher is (310 + x) / 5 >= 77.

The meaning is that she should have a score of 75 or higher to pass.

From the information, Shureka washburn has scores of 69,80,71, and 90 on her algebra tests and she must make on the final exam to pass the course with an average of 77 or higher.

Therefore, the inequality to express the information will be:

(69 + 80 + 71 + 90 + x)/5 >= 77

(310 + x) / 5 >= 77

Crops multiply

310 + x >= 77 × 5

310 + x >= 385

x >= 385 - 310

x >= 75

She needs 77 or more in order to pass the course.

The difference in the latitudes of Athens, Greece, Latitude 38° N, and Sydney, Australia, latitude 34° S is 72° .

We have two different coordinates, 38° N and  34° S

We can find the differnce in two different coordinates by following a few steps.

We have to consider South as negative North. So, we can write 34° S as -34° N.

Hence, we can determine the difference in between two coordinates.

Difference in coordinates ≡ 38° N - 34° S  = 38° N - ( - 34° N ) = 38° N + 34° N = 72°  N

So, we can conclude that, the difference is 72°.

Answer:

  22 ft

Step-by-step explanation:

Given a river that has a depth in January of -5 ft, and a depth in July of -27 ft, you want the difference between the depths in January and July.

The difference between two numbers is found by subtracting the second from the first:

  (January depth) - (July depth) = (-5 ft) -(-27 ft)

  = (-5 +27) ft = 22 ft

The difference between depths in January and July is 22 feet.

Answer:

3.5

Step-by-step explanation:

6 plus 2 equals 8 and if you add 2 to 1.5 you get3.5

Step-by-step explanation:

1.

200 - 7/21 = (200×21 - 7)/21 = (4200 - 7)/21 =

= 4193/21 = 599/3 = (199×3 + 2)/3 =

= 199 2/3

we could have seen that 7/21 = 1/3.

so, then this problem was

200 - 1/3 = (200×3 - 1)/3 = 599/3 = 199 2/3

(see above)

2.

50 - 4/7 = (50×7 - 4)/7 = (350 - 4)/7 =

= 346/7 = (49×7 + 3)/7 = 49 3/7

3.

24 1/4 - 20 3/5 = (24×4 + 1)/4 - (20×5 + 3)/5 =

= 97/4 - 103/5

to calculate this we need to bring both fractions to the save denominator. the LCM (lowest common multiple) of 4 and 5 is 20.

so,

97/4 - 103/5 = (97×5)/(4×5) - (103×4)/(5×4) =

= 485/20 - 412/20 = 73/20 =

= (3×20 + 13)/20 = 3 13/20

4.

10 5/8 - 6 4/9 = (10×8 + 5)/8 - (6×9 + 4)/9 =

= 85/8 - 58/9

the LCM of 8 and 9 is 72.

85/8 - 58/9 = (85×9)/(8×9) - (58×8)/(9×8) =

= 765/72 - 464/72 = 301/72 =

= (4×72 + 13)/72 = 4 13/72

5.

6 1/2 - 5 3/4 = (6×2 + 1)/2 - (5×4 + 3)/4 =

= 13/2 - 23/4

the LCM of 2 and 4 is 4.

13/2 - 23/4 = (13×2)/(2×2) - 23/4 =

= 26/4 - 23/4 = 3/4

Step-by-step explanation:

Answer: Question E: The answer is that A(9) is greater.

Step-by-step explanation:

For questions A and C, you can see that the table is exponentially growing. So the equation will use multiplication. You can also see the value of the equation is growing by x2.

So you could say the table starts at a base of 1/2, then grows exponentially at a rate of 2. (Basically saying the value grows x2 per term). The equation will result in y= 1/2(2)^x

For questions B and D, you can see that the graph is growing linearly. So the equation will use multiplication.

By drawing a line between the lines you can easily see the growth of the triangle. You can then tell the 0th term to 1st term goes right 1 and up 10.

Next, you look at the 1st term to the 2nd term. You can tell that it goes right 1 and up 10. So, the rate is 10 per term. (10x) and it starts at 2 (+2). The equation will result in y=10x+2

Question E, solve each equation by substituting the x by 9.

A(9)

y= 1/2(2)^x

y= 1/2(2)^9

y= 1/2(512)

y=256

B(9)

y=10x+2

y= 10(9) +2

y= 90+2

y=92

The answer is that A(9) is greater.

The algebraic expression for the cost of t T-shirts, not including sales tax is  15.95t - 5.

Given that:-

Cost of a T-shirt = $ 15.95

Discount on coupon = $ 5 (can be used for one T-shirt only)

We have to write an algebraic expression for the cost of t T-shirts, not including sales tax.

We know that,

Total cost of T-shirts = (Number of T-shirts)*(Cost of one t-shirt) - Discount

Hence, we can write,

C(t) = t*(15.95) - 5

C(t) = 15.95t - 5

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A 12-ounce can of soda contains 14 grams of sugar.

Now,

Since, A 12-ounce can of soda contains 14 grams of sugar.

Hence, The amount of soda for 1 ounce of can = 14/12

                                                                        = 1.17 grams

Applying the rules for the constant, logarithm and exponents, the derivative of the given function is of:

f'(x) = 3/x - 6x² - 8/(x^5).

The function is given by:

f(x) = √2^3 + ln(x^3) - 2x^3 - log_3(729) - 2/x^4

The derivative of a sum is the sum of the derivatives, hence:

f'(x) = (√2^3)' + (ln(x^3))' - (2x^3)' - (log_3(729))' - (2/x^4)'

The derivative of a constant is of zero, hence:

Hence:

f'(x) = (ln(x^3))' - (2x^3)' - (2/x^4)'.

The derivative of the logarithm is given by:

ln(h(x))' = (1/h(x)) x h'(x).

Hence:

(ln(x^3))' = 3x²/x³ = 3/x.

The derivative of the power of x is given by:

Hope this helps! :)

The solution for the linear equation is:

a = 1/4.

I believe we have the linear equation:

(a + 2)/3 = 3/4

To solve this, we need to isolate the variable a in one of the sides of the linear equation, to do so, we can start by multiplying both sides by 3.

3*(a + 2)/3 = 3*(3/4)

a + 2= 9/4

Now we can subtract 2 in both sideS:

a + 2 - 2 = 9/4 - 2

a = 9/4 - 8/4 = 1/4

Four ways to find the slope and y–intercept of straight line equation are;

A straight line equation is of the form, y = m•x + c

Where;

m = The slope of the graph of the equation

c = The point the graph intersects the x–axis.

The process by which the slope–intercept form of a straight line equation can be found from the above ways are as follows;

1. Making use of the graph of the equation

When the graph is given, the y–intercept is found from the point the graph crosses the y–axis

Note the y–intercept

Find two points on the graph where coordinates can be obtained

Find the ratio of the rise to the run to get the slope of the graph

[tex] \displaystyle{ Slope, \: m = \frac{ rise}{run} } = \frac{ \triangle y }{\triangle x} [/tex]

With the slope and y–intercept, the equation of the line can be written as; y = m•x + c

2. Obtaining the coordinates of the x–intercept

Given the slope and the y–intercept, the x–intercept can be found by plugging in the values of the slope, m, and the y–intercept, c, in the equation, y = m•x + c, to get the equation of the line

From the equation, the x–intercept can be found by plugging y = 0, to get;

0 = m•x + c

The x–intercept becomes, [tex] \displaystyle \frac{-c}{m} [/tex]

The graph can then be plotted by drawing a line through the x and y–intercept

3. Finding the y–intercept given the slope and the x–intercept

When the slope and the x–intercept and the slope is known, whole number part of the numerator can be added to the x–value of the x–intercept to obtain the x–coordinates of a second point on the graph

The process is repeated to find the y–coordinate of the second point

The slope is calculated using the two points and the equation for the slope given in the first method

4. When two points are known, the slope is calculated using the equation in method 1

The two are joined with a straight line and the y–intercept is obtained from the point the graph intersects the y–axis
