Answer:

-2x² + 3x + 10

Step-by-step explanation:

-(2x² - 3x - 7) + 3

-2x² + 3x + 7 + 3

-2x² + 3x + 10

Step-by-step explanation:

1. ½(2r + 4) - ¼(16 - 8r)=3r-2

2. (8x - 3) - (2x + 6)=6x-9

3. (2 - 7y) - 3(y - 9)=-10y+29

4. 2(3x - 4) - (2x - 5)=4x-3

Answer:

(x - 3)² + (y + 1)² = 65

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

The centre C is at the midpoint of the endpoints of the diameter.

Using the midpoint formula to find C

C = ( [tex]\frac{7-1}{2}[/tex], [tex]\frac{6-8}{2}[/tex] ) = ( [tex]\frac{6}{2}[/tex], [tex]\frac{-2}{2}[/tex] ) = (3, - 1 )

The radius is the distance from the centre to either of the endpoints of the diameter.

Using the distance formula to find r

with C (3, - 1 ) and (7, 6 ) , then

r = [tex]\sqrt{(7-3)^2+(6+1)^2}[/tex]

  = [tex]\sqrt{4^2+7^2}[/tex]

  = [tex]\sqrt{16+49}[/tex]

  = [tex]\sqrt{65}[/tex]

Then equation of circle is

(x - 3)² + (y - (- 1) )² = ([tex]\sqrt{65}[/tex] )², that is

(x - 3)² + (y + 1)² = 65 ← equation of circle

Answer:y=1/5x+5

Step-by-step explanation:

m=slope so plug in the slope you already have which is 1/5

b= y intercept so plug in your y intercept which is 5

Answer: 0.09 mg

Step-by-step explanation:

To find out the milligrams in the blood after 10 hours you just need to replace the 'h' in the equation to 10.

= 5e⁻⁰°⁴ˣ¹⁰

= 5e⁻⁴

= 0.09157819444

= 0.09 mg

Answer:

A) 3

Step-by-step explanation:

divide 77 by 11

you get 7

divide 21 by 7 to find x

x=3

Answer:

Therefore, x = 1 and y = -1 .

Step-by-step explanation:

The steps are :

[tex]4x - 5y = 9 - - - (1)[/tex]

[tex] - 6x + 5y = - 11 - - - (2)[/tex]

[tex](1) + (2)[/tex]

[tex]4x + ( - 6x) = 9 + ( - 11)[/tex]

[tex] - 2x = - 2[/tex]

[tex]x = 1[/tex]

[tex]sub \: x = 1 \: into \: (2)[/tex]

[tex](2)⇒[/tex]

[tex] - 6(1) + 5y = - 11[/tex]

[tex] - 6 + 5y = - 11[/tex]

[tex]5y = - 11 + 6[/tex]

[tex]5y = -5[/tex]

[tex]y = -1 [/tex]

Answer:

I hope it work

Step-by-step explanation:

adding both the equations

4x-5y=9

-6x+5y=-11

-2x+0y=-2

-2x=-2

Now divide both sides by -2

-2/-2 x= -2/-2

Answer:

[tex]\frac{7}{4} u^{-4}[/tex]

Step-by-step explanation:

49/28 is 7/4

Applying the inverse law

u^2-6

u^-4

therefore [tex]\frac{7}{4} u^{-4}[/tex]

Answer:

The same function gave the same y-intercept

Step-by-step explanation:

Y-intercept can be calculated when x is 0. This is easy to figure out the table because it already gave us the value of y when x was 0, which was 3.

For the first function, we know that it has a y-intercept of 3.

For the second function, getting the y-intercept is very easy because you can look at the value of y at x=0. We can physically see that it is 3, meaning that they both have the same y-intercept.

Answer:

x < -10/3 OR x > 20/3

Step-by-step explanation:

|5 - 3x| - 3 > 12

|5 - 3x| > 15

since it's absolute value, you have 2 scenarios to solve:

1) 5 - 3x > 15

-3x > 10

x < -10/3  (when dividing or multiplying by a negative, switch the symbol)

2) -(5 - 3x) > 15

-5 + 3x > 15

3x > 20

x > 20/3

Answer:

p = 7/2 or 3.5

Step-by-step explanation:

-4p + 9 = -5

-4p = -14 (subtracted 9 from both sides)

p = -14/-4 = 7/2

Answer:

p=3.5

Step-by-step explanation:

-4p+9=-5

-9

-4p=-14

p=3.5

Answer:

Linear and non-proportional

Answer:

-212

Step-by-step explanation:

an = a1 + (n-1)d, so

a52 = a1 + 51d

a1= - 8

d = -4 ( because you take away 4 every time)

so a52 = -8 + 51(-4) = -212

Because if the circle is open then it is not equal to but if the circle is darkened then is it equal to

Answer: approximately 3.5 meters.

Step-by-step explanation:

Given: Circumference of the smaller circle is approximately 11 meters.

Circumference of a circle = [tex]\pi d[/tex] , where d= diameter.

Ratio of circumference to diameter = [tex]\pi[/tex]

As per given,

[tex]\pi=\dfrac{11}{d}\\\\\Rightarrow\ d=\dfrac{11}{\pi}\\\\\Rightarrow\ d=\dfrac{11\times7}{22}\ \ \ [\pi=\dfrac{22}7]\\\\\Rightarrow\ d=\dfrac72=3.5\ meters[/tex]

Hence, the diameter of the smaller circle is approximately 3.5 meters.

Answer:

(5x + 7)² = 25x² + 70x + 49 ⇒ C

Step-by-step explanation:

The steps of solving the square binomial: (ax + b)²

1. (ax + b)² = (ax + b)(ax + b)

2. (ax + b)(ax + b) = (ax × ax) + (ax × b) + (b × ax) + (b × b) = a²x² + abx + abx + b²

3. Add the like terms ⇒ a²x² + (abx + abx) + b² = a²x² + 2abx + b²

Then (ax + b)² = a²x² + 2abx + b²

Let us use the same steps to solve the question

∵ (5x + 7)² = (5x + 7)(5x + 7)

∴ (5x + 7)(5x + 7) = (5x)(5x) + (5x)(7) + (7)(5x) + (7)(7)

∴ (5x + 7)(5x + 7) = 25x² + 35x + 35x + 49

→ Add the like terms

∵ 25x² + 35x + 35x + 49 = 25x² + (35x + 35x) + 49 = 25x² + 70x + 49

∴ (5x + 7)(5x + 7) = 25x² + 70x + 49

→ Then equate (5x + 7)² by the right side above

∴ (5x + 7)² = 25x² + 70x + 49

Answer:

4:5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the expression

4/5 x - 1/10 = 3/10

We are to find the value of x

4/5 x = 3/10 + 1/10

4/5 x = 4/10

Cross multiply

4x * 10 = 5 * 4

40x = 20

x = 20/40

x = 1/2

The value of x is 1/2

Answer:

Its 1/2 :)
