Mariana wears her winter coat when the temperature is colder than − 4 C . Write an inequality that is true only for temperatures ( t ) at which Mariana wears her winter coat.

Answer:

The correct answer is c. c is the square of half of b.

Step-by-step explanation:

In all perfect square trinomials, half of the middle number squared gives you the constant. See the example below for proof.

(x + 4)^2

(x + 4)(x + 4)

x^2 + 4x + 4x + 16

x^2 + 8x + 16

You'll notice if you take the middle term (8), cut it in half (4) and then square it (16), the result is the constant.

Answer:

C

Step-by-step explanation:

c is the square of half of b.

To determine the greatest number of people Oscar and Julie can invite within their budget, we can set up an inequality and solve for the variable 'x'. The total cost equation is $90 + $31x ≤ $2,000. Solving this inequality, we find that the greatest number of people they can invite is 61.

To determine the greatest number of people that Oscar and Julie may invite and still stay within their budget, we need to set up an inequality based on the given information. Let's denote the number of people they invite as 'x'. The total cost of the reception hall is $90 (cleanup fee) + $31 (per person) * x (number of people). This should be less than or equal to their budget of $2,000. So, the inequality is 90 + 31x ≤ 2000. To solve for 'x', we need to isolate the variable. Subtracting 90 from both sides, we have 31x ≤ 1910. Dividing both sides by 31, we find x ≤ 61.935. Since we can't have a fraction of a person, the greatest number of people they can invite is 61.

4 * √24

with √24 you find a side, per 4 and you have the perimeter of the square

4 * √24

Answer: T = -32

Step-by-step explanation:

isolate T by multiplying both sides by -4 (the reciprocal of -1/4)

[tex]8 = -\frac{1}{4}T[/tex]

[tex](-4)8 = -(-4)\frac{1}{4}T[/tex]

-32 = T

The domain is the first x of each ordered pair. The domain is 1, -30, -12, -11

The range is the y value : -27,30,21,4

Solution:- Let f and g be the functions such that

                         [tex]f:X\rightarrow  Y\\and\\ g:Y\rightarrow Z[/tex]

can be used to form a function which maps x in X to [tex]g(f(x))[/tex] in Z.  

If z is a function of y, and y is a function of x, then z is a function of x. (transitive property)

Hence the composite function is given by

[tex]g of : X\rightarrow Z[/tex] , defined by [tex](gof)(x)=( g(f(x)) x)[/tex] for x in X.

Now , for the function g(x) into the function for f(x), we have to work from the inside out by substituting the expression. So by this way composition of function related to order of operations.

z=24 degrees. To explain, you can solve for x by making the equation 2x+48=180 since 180 degrees is the angle of a straight line. Once you solve for x, you add that number to 90. Finally, subtract that number from 180 to get z. You subtract from 180 because a triangle's total angle sum is always 180

Y = 42

The values of A and B of the given equation with the given coordinates are; A = 5 and B = -4

We are told the equation is;

Ax + By = 10

Since the equation goes through (6,5) and (-2,-5), then it means we have two simultaneous equations as;

6A + 5B = 10   ----(eq 1)

-2A - 5B = 10  ----(eq 2)

Add eq 1 to eq 2 to obtain;

4A = 20

A = 20/4

A = 5

Now, put 5 for A in eq 1 to get;

6(5) + 5B = 10

30 + 5B = 10

-5B = 30 - 10

-5B = 20

B = -20/5

B = -4

Thus, in conclusion, the values of A and B are 5 and -4 respectively.

Values of A and B in the equation Ax+By=10, that pass through points (6,5) and (-2,-5), can be calculated by plugging these points into the equation, resulting in two simultaneous equations. On solving them, you find that A = 1 and B = -1.

In order to determine the values of A and B in the equation Ax+By=10 that passes through the points (6,5) and (-2,-5), first we plug these points into the equation. This will result in two simultaneous equations.

For the point (6,5), the equation becomes 6A + 5B = 10. For the point (-2,-5), the equation becomes -2A - 5B = 10. Solving these two simultaneous equations, you will obtain A = 1 and B = -1.

Answer:

[tex]y = 5 + 0.003(2^{x})[/tex]

Step-by-step explanation:

If a base shipping charge of $ 5 is collected, it means that regardless of the amount of money spent, a base payment of $ 5 must be made for the shipment. Therefore the graph of the exponential function must move 5 units up on the positive y axis. Your new cutoff point with the positive y axis will be y = $ 5.003

Therefore, the new function that represents the shipping cost will be:

[tex]y = 5 + 0.003(2^{x})[/tex]

with [tex]x \leq 20[/tex]

The answer would be A, 3(x-6)(x+2)

In order to make three consecutive numbers, subtract one and add one to 60.

[tex]60 - 1 = 59\\60 + 1 = 61[/tex]

You get 59, 60, and 61.

61 is the oldest age, that's your answer.
