Answer:

c = [tex]\frac{49}{4}[/tex]

Step-by-step explanation:

Given

x² + 7x + c

To complete the square

add ( half the coefficient of the x- term )² to x² + 7x

x² + 2([tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] , thus

= (x + [tex]\frac{7}{2}[/tex] )² ← a perfect square

with c = [tex]\frac{49}{4}[/tex]

Answer: it is linear

Step-by-step explanation: Find the degree of the equation to determine if linear.

Answer:

Yes

Step-by-step explanation:

Look up Desmos, it is graphing calculator... it will really help. REAL EXPLANATION: You put one point on -4, then do rise over run (2/1x), thus go up to over one. So on and so forth; this will result in a linear line.

Zeros :

[tex]x = - 2[/tex]

[tex]x = 4[/tex]

[tex]x = 7[/tex]

Thus ;

[tex]x + 2 = 0[/tex]

[tex]x - 4 = 0[/tex]

[tex]x - 7 = 0[/tex]

Multiply above equations :

[tex](x + 2)(x - 4)(x - 7) = 0[/tex]

Expand

[tex]( {x}^{2} - 2x - 8)(x - 7) = 0[/tex]

[tex] {x}^{3} - 7 {x}^{2} - 2 {x}^{2} + 14x - 8x + 56 = 0 \\ [/tex]

[tex] {x}^{3} - 9 {x}^{2} + 6x + 56 = 0[/tex]

[tex]y = f(x) = {x}^{3} - 9 {x}^{2} + 6x + 56 \\ [/tex]

Done...

Answer:

$16 profit per sweater

Step-by-step explanation:

$130-$50=$80

$80÷5=$16

Solution :

From the figure,

The coordinates of --

A = (-5,-3)

B = (-6,-1)

C = (-3,-1)  

D = (-2,-3)

When it undergoes reflection about x-axis, we have the coordinates of the quadrilateral as

A' = (-5,+3)

B' = (-6,+1)

C' = (-3,+1)

D' = (-2,+3)

Now A'B'C'D' is translated 3 units to right, so the coordinates will be --

A" = (-2,3)

B" = (-3,1)

C" = (0,1)

D" = (1,3)

When the quadrilateral moves third and two units up, we get

A"' = (3,3)

B"' = (2,1)

C"' = (5,1)

D"' = (6,3)

Step-by-step explanation:

Step-by-step explanation:

x + 1 + 2x + 2 + 12x - 18 = 180 (sum angles in triangle)

15x - 15 = 180

15x = 195

x = 13deg

Topic: Angles

If you like to venture further, do check out my insta (learntionary) where I constantly post math tips! Thanks!

Step-by-step explanation:

(x+1)°+(2x+2)°+(12x-18)°=180°

15x+3°-18°=180°

15x+15°=180°

15x=180°-15°

x=165°/15°

x=11° Answer..

Answer:

I think its A

Answer:

D

Step-by-step explanation:

The y intercept is 2, visible on the graph.

The way I think about counting slope is (in this case)

"up one, over 5"

1/5

c=1/5m+2

D is your answer if there are 4 options (A, B, and C are incorrect; D isn't shown so I assume it's what I got)

Answer:

x = 4.52984

Step-by-step explanation:

Since the triangle has a right angle you need to use the the trigonometric function cos (theta which is the angle given that isn't 90°) = adjacent / hypotenuse (adjacent is the side close to the angle you're using which is 22° and the hypotenuse is the longest side of the triangle that is in the away from the right angle)

From there you plug in the numbers which now become cos (22°) = 4.2 / x

Then you isolate the x by multiplying it to both sides so it's on the left and divide both sides by cos (22°) which will end you up x = 4.2 / cos (22°)

Then you just divide and you 4.52984

Ben is incorrect because Ben did not answer the question according to the available information. The fact that subtracting 43 from 30 is easier for Ben does not mean it is the correct answer.

Answer:

  y > 11/2

Step-by-step explanation:

Subtract 2y+3 to get the variable term alone on one side.

  2y > 11

  y > 11/2 . . . . . . divide by the coefficient of y

Answer:

Step-by-step explanation:

Your bill is $62.50

$62.50 * .06 = $3.75 (this is your sales tax added)

So your total is up to: $66.25

Adding the tip the same way using $66.25 *.18 = $11.93

Tip would be $11.93

Total coming to: $78.17

hope this helps

Answer:

$77.50

Step-by-step explanation:

Tax:

62.50x0.06= 3.75

3.75+62.50= 66.25

Tip:

62.50x0.18= 11.25

Answer:

66.25+11.25= 77.50

Answer:

1st one, 3rd one, and 5th one.

Answer:

The first, third and the fifth.

Step-by-step  explanation:

First one is equivalent

√(8^2*8^2)

= √64*64

= √64.

8^1/2 * 8^1/2

= 8^1

= √64.

√(16*4)

= √64.

Answer:

C. y = 945x + 2,835

Step-by-step explanation:

Each pay period 945 dollars is deposited so that's the slope, which x stands for each pay period. She already started with 2,835 in her savings account so that is the y-intercept.

Slope: 945x

Y- intercept: 2,835

Therefore,

equation: y = 945x + 2,835
