Answer:

1) y = 5x + 100

2) y = -10x + 375

Step-by-step explanation:

The slope intercept form of an equation is expressed as y = mx+c

m is the slope

c is the intercept

1) Using the coordinate points (0,100) and (1, 105)

slope m  = 105-100/1-0

m = 5/1

m = 5

Substitute m = 5 and (0,100) into the formula y = mx+c

100 = 5(0)+c

100 = 0 + c

c = 100

The required equation is y = 5x + 100

2) Using the coordinate points (0,375) and (5 325)

slope m  = 325-375/5-0

m = -50/5

m = -10

Substitute m = -10 and (0,375) into the formula y = mx+c

375 = -10(0)+c

375 = 0 + c

c = 375

The required equation is y = -10x + 375

Answer:

3) [tex]x^{2}[/tex] + 4x - 21

Step-by-step explanation:

(x - 3)(x + 7)

Distribute:

x(x + 7)

-3(x + 7)

x(x) = [tex]x^{2}[/tex]

x(7) = 7x

-3(x) = -3x

-3(7) = -21

Combine like terms:

7x - 3x = 4x

Put it together:

[tex]x^{2}[/tex] + 4x - 21

Answer: x²+ 4x - 21

Let's do this step-by-step.

1. Apply the foil method. (formula: (a + b)(c + d) = ac + ad + bc + bd)

F - First

O - Outer

I - Inner

L - Last

= xx + x × 7 + (-3)x + (-3) × 7

2. Apply the minus and plus rules. + (-a) = -a

xx + 7x - 3x - 3 × 7

3. Simplify.

Hence, the answer is x² + 4x - 21

Let get x as a number of small circles.

Area of big circle = Area of all small circles

(Here . implies multiplication)

22/7 . 35 cm .35cm = 22/7 . 7cm .7cm .x

x =  (22/7 . 35 cm .35cm) / (22/7 . 7 cm .7cm)

x = (35 . 35) /(7.7)

x = 25

7C10 = 10!/(7!)(10-7)!

7C10 = 10!/(7!)(3!)

7C10 = (10 x 9 x 8 x 7)/(7 x 6 x 5)(6)

7C10 = (10 x 9 x 8)/6

7C10 = 720/6

7C10 = 120

Answer:

A. Inscribed Angle

Step-by-step explanation:

Because the angles are inscribed in the circle, the angle lie on arcs which mean that the angles have to add up to 360 degrees just like a circle is 360 degrees, making it a quadrilateral that is inscribed!

The missing information in the paragraph proof should be considered as the Inscribed Angle.

In terms of geometry, an inscribed angle should be the angle that should be created in the interior of a circle at the time when two chords intersect on the circle. Since the angles should be inscribed in the circle so here the angles should be added up to the 360 degrees same as like the circle also at the same time it should make the quadrilateral

Therefore, The missing information in the paragraph proof should be considered as the Inscribed Angle.

Answer:

Is Mary a guy?  :|  

Step-by-step explanation:

I did this by just a good guess  , not really the right way

2000*.45=900  ( 900 is the old savings)

2000*.2 =400   ( how much her salary went down by )

2000-400=1600 ( new salary )

1600*.45 = 720    ( 45% of new salary is new savings

900-720=180      ( change in savings is 180 , the amount the question asks for)

Mary's old salary was 2,000

Answer:

A = 54.11 unit²

Step-by-step explanation:

Given that :

A = θ/360 * πr²

A = 62/360 * π(10)²

A = 0.1722222 * π * 100

A = 54.105206

A = 54.11 unit²

Answer:

10[tex]x^{2}[/tex]  -20x -12.5 inches

Step-by-step explanation:

Triangle Area Equation:

Area of triangle = [tex]\frac{1}{2} * base * height[/tex]

base = 10x + 5

height = 2x - 5

1/2 (10x + 5) (2x - 5)

= 1/2 (20[tex]x^{2}[/tex] - 50x + 10x - 25)

= 1/2 ( (20[tex]x^{2}[/tex] - 40x - 25)

= 10[tex]x^{2}[/tex]  -20x -12.5 inches

To find the median, you order the numbers from least to greatest, then find the middle number.

3,7,3,2,7,9

2,3,3,7,7,9

There are two middle numbers, so we have to find the middle of the two.

3,4,5,6,7

5 is the median, so the answer is B.
