Dovator [93]3 years ago

Answer:

undefined

Step-by-step explanation:

4 - 9 = x - 2

-5 = x - 2

-3 = x

this is a vertical line (parallel to the y-axis) at x = -3.

that means the slope of this line is "undefined". or some would call it "infinite".

as the slope is the ratio of y/x describing how many units y changes, when x changes a certain amount of units.

now the change of x for this line is constant 0.

so, we have a slope y/0, which is undefined.

For each problem below put the lettered measures in order for greatest to the least
Len [333]

Angles can be used to estimate the side lengths of a shape.

The letters in order of greatest to least are (a), (b) and (c)

The sum of angles at side (a) is:

a = 30 + 50

a = 80

The sum of angles at side (c) is:

c = 50 + 90

c = 140

The sum of angles at side (b) is:

b = 40 + 90

b = 130

So, we have:

a = 80

b = 130

c = 140

The smaller the base angles, the longer the side.

Hence, the letters in order of greatest to least are (a), (b) and (c)

Identify the solution(s) of <br><img src="https://tex.z-dn.net/?f=y%20%5E%7B2%7D%20%20-%202y%20-%208%20%3D%207" id="TexFormula1"
Burka [1]

Answer:

y= 5 and -3

Step-by-step explanation:

subtract 7 from both sides to get y^2-2y-15=0

factor the equation to get (y-5)(y+3)=0

add five on both sides to get y=5 and subtract 3 on both sides to get y=-3

give the standard form, degree, leading coefficient and the constant term of the function h(x) = (2x+1)² (2x-3)​
Softa [21]

Answer:

The standard form is: h(x) = 8x^3 - 4x^2 - 10x - 3

The function is of the 3rd degree.

The leading coefficient is 8.

The constant term is -3.

Step-by-step explanation:

Placing in standard form:

To place in standard form, we solve the operations. So

h(x) = (2x+1)^2(2x-3)

h(x) = (4x^2 + 4x + 1)(2x - 3)

h(x) = 8x^3 - 12x^2 + 8x^2 - 12x + 2x - 3

h(x) = 8x^3 - 4x^2 - 10x - 3

Degree:

The degree is given by the highest power of x, which, in this exercise, is 3.

Leading coefficient:

The leading coefficient is the term that multiplies the highest power of x. In this exercise, the higher power of x is x^3, which is multiplied by 8. So the leading coefficient is 8.

Constant term:

The constant term is the one which does not multiply a power of x. So in this exercise, it is -3.

Keta sold tickets for her school play at $6 for students, and $9 for adults. She sold 15 adult tickets and made a sales total of
ss7ja [257]

Answer:

Let x be the number of tickets sold to adults and y the number sold to students:

x + y = 315. But we know that y was double x, then :

y = 2x

Plug the value of y (in the 1st equation) by 2x:

 x+ 2x = 315

3x = 315

and x = 105 (which is the number of tickets sold to adults
