The slope-intercept form of (5,-3) and (4,0) is y = -3x + 12.

The slope intercept form is simply writing an equation of a line so that the slope or steepness and y-intercept i.e. where the line crosses the vertical y-axis are immediately apparent.

The slope-intercept equation is y = mx + c, where x and y are two variables, and m is slope.

Slope m = [tex]\frac{y2-y1}{x2-x1}[/tex]

Let,

(x1, y1) = (5, -3)

(x2, y2) = (4, 0)

Slope (m) = [tex]\frac{0 - (-3) }{4 - 5}[/tex]

                = [tex]\frac{3}{-1}[/tex]

                = -3

By substituting x, y, and m values in the equation we can get the value of c.

Consider x = 4 , y = 0, m = -3

y = mx + c => 0 = (-3)4 + c

                      c = 12

Therefore, the slope-intercept form of (5,-3) and (4,0) is y = -3x + 12.

The total number of water glasses on the shelf may be 39, 63 or 87.

Given, that there were more than 24 glasses, but less than 100 glasses.

If the glasses were in rows of 6, there would be 3 left over.

If the glasses were in rows of 8, there would be 7 left over.

Let the number of glasses be x,

So, x = 6k1 + 3

=> (x - 3) is a multiple of 6

x = 8k2 + 7

=> (x - 7) is a multiple of 8

Now, the numbers that can satisfy the given conditions are,

39 , 63 & 87.

So, the total number of glasses may be 39, 63 or 87.

Hence, the total number of water glasses on the shelf may be 39, 63 or 87.

The first option Focus(2,-0.5); directrix x=0 of the parabola is the correct answer.

What is a parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

The general equation of a parabola is as follows:

[tex](y-k)^2=4a(x-h)[/tex]

Now, consider the given equation.

[tex](y+0.5)^2=4(x-1)[/tex]

Now, compare with the standered equation.

a=1, k=-0.5 and h=1

Here, a is positive hence, the parbola opens right side.

Focus is given by the following coordinate:

[tex](h+a,k)=(1+1,-0.5)\\=(2,-0.5)[/tex]

Now, equation of diretrix is given by the following expression:

[tex]x=h-a\\x=1-1\\x=0[/tex]

Hence, the first option Focus(2,-0.5); directrix x=0 is the correct answer.

The total surface area of this prism is: 620 cm².

First step it to find the Area of isosceles triangles:

Area of isosceles triangles = [(24 × 5) ÷ 2]

Area of isosceles triangles (120 ÷ 2)

Area of isosceles triangles = 60 cm²

Second step is to find the area of 2 triangles

Area of 2 triangles = 60 cm² × 2

Area of 2 triangles = 120 cm²

Third step is to find the Area of 2 identical rectangles

Area of 2 identical rectangles= (10 × 13 ) × 2

Area of 2 identical rectangles=  260 cm²

Fourth step is to find the  bottom area of rectangle

Area of rectangle  = 24 × 10

Area of rectangle = 240²

Now let find the total surface area

Total surface area =120 + 260 + 240

Total surface area = 620 cm²

Therefore the surface area is 620 cm².

The discriminant of the equation f(x) = 2x^2-10x+8 [tex]\neq[/tex] 36

To find out the discriminant of f(x)=2x^2-10x+8

The formula for the discriminant is represented by b²-4ac.

This equation is in general form, which is ax² + bx + c = 0.

So, lets assume the values to be

a = 2

b = -10

c = 8

The discriminate that we need to find out in the equation below is

D = b²-4ac

[tex]D = -10^{2} - 4(2)(8)[/tex]

D = -100 - 64

D = -164 which is not a nice number

As the discriminant had a negative value of -164.

This means there are no real solutions to the equation, because the discriminant is negative.

Hence the discriminant of the equation f(x) = 2x^2-10x+8 [tex]\neq[/tex] 36

If Sarah can text 91 words in 14 minutes, then at this rate she will type 65 words in 10 minutes

Number of minutes to types 91  words = 14 minutes

Here we have to use the unitary method to solve the problem

Time taken to type 1 word = Number of minutes to types 91  words / 91

Substitute the values in the equation

= 14  / 91

= 2 / 13

Time taken to type 65 words =  Time taken to type 1 word × 65

Substitute the values in the equation

= (2/13) × 65

= 10 minutes

Hence, if Sarah can text 91 words in 14 minutes, then at this rate she will type 65 words in 10 minutes

8. -a+b-7

9. m=(y-b)/x

Answer:

first one: C

second one: A

Step-by-step explanation:

4a - 5 + 3b - 2 - 2b - 5a

combine a terms:

-a - 5 + 3b - 2 - 2b

combine b terms:

-a - 5 + b - 2

combine numbers:

-a  + b - 7 (this is option c)

_____________________

y = mx + b, solve for m

subtract b from both sides:

y - b = mx + b - b

y - b = mx

divide both sides by x:

(y - b)/x = mx/x

m = (y - b)/x (this is option a)

Step-by-step explanation:

when we have an equation

y = ax + b

then "a" is the slope.

in our equation we see

1/2(6x ...) = 6/2 x ... = 3x ...

so, the slope is 3.

Answer: (0,-13)

3 (2q - s)(p + r) is the factor form of expression 6pq-3rs-3ps+6qr.

A factor is a number that divides another number, leaving no remainder

The given expression is 6pq-3rs-3ps+6qr

We need to factorize the expression.

6pq-3rs-3ps+6qr

= 3 (2pq - rs - ps + 2qr)

= 3 (2pq + 2qr -ps - rs)

= 3 (2q(p + r) -s(p + r))

= 3 (2q - s)(p + r)

Hence, 3 (2q - s)(p + r) is the factor form of expression 6pq-3rs-3ps+6qr.
