The difference between the monthly high and low temperatures was less than 27° Fahrenheit. The monthly low temperature was –2° Fahrenheit. Select the choices that make the inequality and statement about the possible monthly high temperature correct.

We are given the following inequality.

[tex]5x+38 \leq 4(2-5x)[/tex]

Apply the distributive property on the right side:

[tex]5x+38\leq 8-20x[/tex]

Add both sides by 20x:

[tex]5x+38+20x\leq 8-20x+20x[/tex]

[tex]25x+38\leq 8[/tex]

Subtract both sides by 38:

[tex]25x+38-38\leq 8-38[/tex]

[tex]25x\leq -30[/tex]

Divide both sides by 25:

[tex]25x/25\leq -30/25[/tex]

[tex]x\leq -6/5[/tex]

Out of all the options, only option A accurately depicts this inequality. Thus, the answer is option A.

The equation of the function shown in the graph is f(x) = x² + 6x + 7.

A parabola is a two dimensional figure on a plane which is U shaped and any point on the parabola is at an equal distance from a fixed point called focus and a fixed line called directrix.

We know that, equation of a parabola in vertex form is,

f(x) = a (x - h)² + k, where (h, k) represents the vertex of the parabola.

Here, it is already given that, vertex form of a quadratic function is

f(x) = (x − h)² + k

That is, a = 1

Vertex = (-3, -2)

Equation of the function is,

f(x) = (x - -3)² + (-2)

f(x) = (x + 3)² - 2

f(x) = x² + 6x + 9 - 2

f(x) = x² + 6x + 7

Hence the equation of the function is f(x) = x² + 6x + 7.

C. y. < -2x - 4 This would be the correct answer

Answer:

Step-by-step explanation:

The surface area of the triangular pyramid can be found by adding the area of the base to the area of the lateral faces. The lateral faces are congruent isosceles triangles.

The area of the base can be found using the formula for the area of an equilateral triangle:

A = (s^2 * √3) / 4, where s is the length of one side of the equilateral triangle base.

Since the area of the base is given as 15.6 in², the length of one side of the base can be found:

15.6 = (s^2 * √3) / 4

s^2 = (4 * 15.6) / √3

s^2 = 64 / √3

s = 4 * √(64 / 3)

s = 4 * 4

s = 6

So, each side of the base measures 6 in.

Next, find the surface area of the lateral faces. The lateral faces are congruent isosceles triangles with a slant height of 8 in and base length of 6 in.

The area of each lateral face can be found using the formula for the area of an isosceles triangle:

A = (b * h) / 2, where b is the base length and h is the height.

For this pyramid:

b = 6 in

h = 8 in

A = (6 * 8) / 2 = 24 in²

Since there are three lateral faces, the total area of the lateral faces is 3 * 24 in² = 72 in².

Finally, the surface area of the pyramid is the sum of the area of the base and the area of the lateral faces:

A = base area + lateral face area

A = 15.6 in² + 72 in² = 87.6 in²

On solving the provided question, we cans ay that ratio is 2:3=> 2x + 4x = 4 => x = total fat is 6.6666666667

Ratios show how often one number is contained in another in mathematics. For instance, the ratio of oranges to lemons in a fruit dish is 8 to 6 if there are 8 oranges and 6 lemons present. In a similar vein, the proportion of oranges to whole fruit is 8, while that of lemons to oranges is 6:8. A ratio is an ordered pair of numbers a and b that is expressed as a / b, with b not equal to zero. An equation equating two ratios is known as a ratio. The ratio can be expressed as 1:3, for instance, if there is 1 boy and 3 girls (for every boy she has 3 girls) 3/4 are girls, while 1/4 are boys.

The ratio of saturated fat to total fat in a caramel frappucino is 2 to 3

There are 4 more grams of total fat than saturated fat

The solution is,

a) Melissa's monthly payment on the promissory note is $133.10.

b) The total of Melissa's monthly payments is $6,388.80.

c) The total finance charge is $388.80.

Using an online finance calculator, we can compute the promissory note's monthly payments and finance charges (cost of credit).

The sum of the monthly payments is the total payments made by Melissa, consisting of the amount of the promissory note and the finance charges.

here, we have,

N (# of periods) = 48 months (4 years x 12)

I/Y (Interest per year) = 3.11%

PV (Present Value) = $6,000

FV (Future Value) = $0

Results:

PMT = $133.10

Sum of all periodic payments = $6,388.80

Total Interest = $388.80

Thus, Melissa's finance charge on the promissory note is $388.80, with a monthly payment of $133.10 for 4 years.

Step-by-step explanation:

Yes, the two lines are parallel.

Lines are parallel if they have the same slope. The slope of a line can be found by rearranging the equation into the slope-intercept form: y = mx + b, where m is the slope.

For line L: y = 5x + 1, so the slope is 5.

For line L^2: 2y - 10x + 3 = 0, rearrange to get y = -5x + (3/2). The slope of the line is -5.

Since the two lines have the same slope (both 5), they are parallel.

The expressions are considered correct because they have been completely factored, meaning they have been written in the form of "a common factor times another expression". This means that the expression on the right side of the equal sign can be simplified into its simplest form.

For example, in the expression 16a5−20a3=4a3(4a2−5), the 4a3 factor is common to both 16a5 and 20a3, so it can be factored out. The expression then becomes 4a3 times (4a2−5), which is the completely factored form.

Similarly, in the expression 12a3+8a=4(3a3+2a), the factor of 4 is common to both the expressions on the right side, so it can be factored out. This results in the completely factored form of 4 times (3a3+2a).
