Could someone help me with this!!! ​

Answer:

D

Step-by-step explanation:

If something is not constant we know it is non-linear. We know this is not constant because when graphed, the line is not straight.

Answer:

D.

Step-by-step explanation:

Here the rate of change is not constant. For example:

10-5 / 20-17 = 5/3

13-10/23-20 = 3/3 = 1

Answer:

Q1.acceleration=3u/20

Q2.a=13.908m/s

b.50.069km/hr

Step-by-step explanation:

Q1.V=U+at

v=u+at

substituting we have a=3u/20m/s^2 in terms of u

Q2.velocity =distance/time

v=100/7.19=13.908m/s

p=5

Answer:

5 plates

Step-by-step explanation:

First, make two fraction bars, one with the ratio 10/14 the other with the top blank and 7 on the bottom. Next, find how much to multiply 7 by to get 14. Use the number you get to divide 10 by. Then you should get 5. Hope this helped!

Answer: (6, -6)

Step-by-step explanation:

so midpoint =([tex]\frac{X1+X2}{2}[/tex],[tex]\frac{Y1+Y2}{2}[/tex])

for x co ordinate

[tex]\frac{-2+X2}{2}[/tex]=2

-2+X=4            (X2=x co ordinate point for b, can be written as just x now)

X=6

x co ordinate of B= 6

y co ordinates of y

[tex]\frac{-8+Y2}{2}[/tex]=-7

-8+Y=-14

Y=-6

co ordinates B (6,-6)

for proof/extra explanation (NOT necessary for working):

[tex]\frac{Y1+Y2}{2}[/tex]

=[tex]\frac{(-2)+6, (-8)+(-6)}{2}[/tex]

=[tex]\frac{4, -14}{2}[/tex]

Slope and y-intercept form of a line: y =mx + b

m -> Slope;     b -> y-intercept

y = (-1/5)x + 9

Slope = -1/5

y-intercept = 9

Answer:

990 cm²

Step-by-step explanation:

Given ratio of radii = a : b , then

ratio of areas = a² : b²

Here

ratio of radii = 50 : 30 = 5 : 3 , then

ratio of areas = 5² : 3² = 25 : 9

let x be the area of sector DEF , then using proportion

[tex]\frac{25}{2750}[/tex] = [tex]\frac{9}{x}[/tex] ← [tex]\frac{ratio}{area}[/tex]

cross- multiply

25x = 24750 ( divide both sides by 25 )

x = 990

Area of sector DEF = 990 cm²

Answer:

hi

Step-by-step explanation:

We see a set of linear equations. Hence, a system of linear equations. So we solve them by process of elimination, multiplying the top equation by 5 to eliminate first such that  

(2x+y=20)*5

6x-5y=12

-----------------------------------------

10x+5y=100

6x-5y=12  

--------------------------------

16x = 112 .............After dividing 16 we get  

x = 7

Now we plug x  = 7 back into the original first equation to obtain the y value such that  

2(7) + y = 20  

12 + y = 20

-12         -12

------------------

y = 8

Answer:

(3x - 2)(3x - 4).

Step-by-step explanation:

9x^2-18x+8

Use the 'ac' method:

9 * 8 = 72.

We need 2 numbers whose product is + 72 and whose sum is -18

These are -12 and -6 so we rewrite the expression as:

9x^2 - 12x - 6x + 8       Now we factor by grouping:

= 3x(3x - 4) - 2(3x - 4)   The 3x - 4 is common so we have:

(3x - 2)(3x - 4).

The factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The quadratic expression is given below.

⇒ 9x² - 18x + 8

Factorize the quadratic expression, then the factors are given as,

⇒ 9x² - 18x + 8

⇒ 9x² - (12 + 6)x + 8

⇒ 9x² - 12x - 6x + 8

⇒ 3x(3x - 4) -2(3x - 4)

⇒ (3x - 2)(3x - 4)

Then the factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).

Answer:

Step-by-step explanation:

they are (-5,-4) hope this helped

Answer: the answer is (-4,-5)

Step-by-step explanation: hopefully that helps

angle 1 = 180-110 = 70 degrees (linnear pair)

angle 2= 180-115 = 65 degrees (linnear pair)

angle 3 = angle 2 = 65 degrees (corresponding angles)

angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)

(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)

angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees

angle 6 = angle 7 = 45 degrees ( vertical angles)

angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)

angle 9 =angle 6 = 45 degrees (corresponding angles)

angle 5=angle 9=45 degrees (vertical angles)

Step-by-step explanation:

Remark

This is a Pythagorean Problem

Formula

a^2 + b^2 = c^2

a = 5

b = ?

c = 9

Solution

5^2 + b^2 = 9^2             Expand the givens

25 + b^2 = 81                  Subtract 25 from both sides

25-25+b^2 = 81- 25

b^2 = 56

√b^2 = √56

b = √8*7

b = √2*2*2*7

b = 2 √2*7

b = 2 √14

For every 2 prime factor under the square root sign, 1 of them can be taken out from under the root and the other is thrown away.

Answer:

x = 27.8

y = 35

Step-by-step explanation:

∡D ≅ ∡A, therefore:

65 = 2y - 5

70 = 2y

y = 35

EF ≅ BC, therefore:

2x + y = 90.6

2x + 35 = 90.6

2x = 55.6

x = 27.8
