Answer:

Step-by-step explanation:

y=(x+5)(x+4)=x²+5x+4x+20=x²+9x+20=x²+9x+(9/2)²-(9/2)²+20

[tex]y=(x+\frac{9}{2} )^2-\frac{81}{4} +20\\y=(x+\frac{9}{2})^2-\frac{81}{4}+\frac{80}{4}\\y=(x+\frac{9}{2})^2-\frac{1}{4}[/tex]

Answer:

5 is NOT a solution to the equation.

t = 6

Step-by-step explanation:

Step 1: Write out equation

2t - 1 = 11

Step 2: Add 1 to both sides

2t = 12

Step 3: Divide both sides by 2

t = 6

there both the same number its just that one is on top and the other is on bottom

Answer:

(-1,4.5)

Step-by-step explanation:

You would have to use the formula for midpoint. 5+-3/2= -1

3+6/2= 4.5  which would be -1 for x and 4.5 for y.

Q: How are they the same answer?

A: You divide both of them by the number with x.

Divide both sides by -2

[tex]-2x/-2=10/-2\\x=-5[/tex]

Divide both sides by -5

[tex]-5x/-5=25/-5\\x=-5[/tex]

That's how both of them are equivalent to each other.

[tex]\text{Hey there!}[/tex]

[tex]\text{Are the equations -2x = 10 \& -5x = 25 equivalent?}[/tex]

[tex]\text{-2x = 10}[/tex]

[tex]\text{DIVIDE both sides by -2}[/tex]

[tex]\bf{\dfrac{-2x}{-2} = \dfrac{10}{-2}}[/tex]

[tex]\text{Cancel out \dfrac[-2x}{-2} because it gives 1}[/tex][tex]\text{Cancel out:}\ \bf\dfrac{-2x}{-2} \text{ because it gives you 1}[/tex]

[tex]\text{Keep:} \bf{\dfrac{10}{-2}}\text{ because it gives you the result of x}[/tex]

[tex]\bf{\dfrac{10}{-2} = -10\div2 \rightarrow -5}[/tex]

[tex]\boxed{\underline{\text{\bf{x = -5}}}}\checkmark[/tex]

[tex]\text{-5x = 25}[/tex]

[tex]\text{DIVIDE both sides by -5}[/tex]

[tex]\bf{\dfrac{-5x}{-5}= \dfrac{25}{-5}}[/tex]

[tex]\text{Cancel out:}\ \bf{\dfrac{-5x}{-5}}\text{ because it gives you 1}[/tex]

[tex]\text{Keep:}\ \bf{\dfrac{25}{-5}}\ \text{ because it gives you the result of x }[/tex]

[tex]\bf{\dfrac{-25}{5} = -25 \div 5 \rightarrow -5 }[/tex]

[tex]\boxed{\underline{\bf{x = -5}}}\checkmark[/tex]

[tex]\boxed{\text{To answer your question: \boxed{\bf{YES}} because both x's equal to -5}}[/tex]

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{a = - 11}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{4a - 2(3a + 8) = 6}[/tex]

Distribute 2 through the parentheses

[tex] \longrightarrow{ \sf{4a - 6a - 16 = 6}}[/tex]

Collect like terms

[tex] \longrightarrow{ \sf{ - 2a - 16 = 6}}[/tex]

Move 16 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{ - 2a = 6 + 16}}[/tex]

Add the numbers: 6 and 16

[tex] \longrightarrow{ \sf{ - 2a = 22}}[/tex]

Divide both sides by 2

[tex] \longrightarrow{ \sf{ \frac{ - 2a}{ - 2} = \frac{22}{ - 2}}} [/tex]

Calculate

[tex] \longrightarrow{ \sf{a = - 11}}[/tex]

Hope I helped !

Answer:

61.3

Step-by-step explanation:

two vertical angles add up to 180°

so (x+3)+(2x+7)=180°

open brackets & collect like terms

x+3+2x-7=180°

3x+-4=180°

3x=184°

x=61.3 after dividing by 3 on both sides

432 characters can be expected to fit per yard of text. Therefore, option D is the correct answer.

Given that, a text font fits 12 characters per inch.

We need to find how many characters can be expected per yard of text.

To convert a yard measurement to an inch measurement, multiply the length by the conversion ratio. The length in inches is equal to the yards multiplied by 36.

Let x be the number of characters to be used in a yard.

12 characters / in = x/ 36 in

(12 characters * 36 in) / in = x

x = 432 characters

Therefore, option D is the correct answer.

D. The number of weeks after the first week

Step-by-step explanation:

Answer:

5.4ft²

Step-by-step explanation:

Area of yellow region

= area of square - area of circle

Area of square= side ×side

Area of circle= πr²

5ft is the length of a side of the square, as well as the diameter of the circle.

Diameter= 2 ×radius

Radius or circle, r

= 5 ÷2

= 2.5 ft

Area of yellow region

= (5 ×5) - π(2.5²)

= 25 -6.25π

= 5.4 ft² (to nearest tenth)

Answer:

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

Step-by-step explanation:

The equation of the line is;

2(x - 3) - 6y = 10

Placing the line in slope intercept form we get;

6y = 2x - 6 - 10

6y = 2x - 16

Dividing throughout by 6 we get;

y = [tex]\frac{2}{6}[/tex]x - [tex]\frac{16}{6}[/tex]

Simplifying gives;

y = [tex]\frac{1}{3} x +2 \frac{2}{3}[/tex]

So the slope of this line = [tex]\frac{1}{3}[/tex]

Answer:

y = 3x

Step-by-step explanation:

Direct proportion equation is

y = kx

6 = k*2

Divide each side by 2

6/2 = 2k/2

3 =k

The equation is y = 3x

Formula for direct proportion: y = kx

Solution:

6 = 2k

~Divide 2 to both sides

3 = k

Best of Luck!
