Answer:

g(x) = (x + 3)²

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = ( - 3, 0 ) , then

g(x) = (x - (- 3))² + 0 , that is

g(x) = (x + 3)²

Answer:

y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."

Step-by-step explanation:

A parallel line has the same slope as the reference line,

The reference line is 9x-4y = -5x4, as written.  I'm not sure the 4 belongs, but I'll assume it is written correctly.  I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20.  I'll assume -20:

9x-4y = -20

Put the equation into standard slope-intercept form:  Y = mx + b, where m is the slope and b is the y-intercept (the value of y when  x = 0).

-4y = -9x - 20

y = (9/4)x + 5

This line has a slope of (9/4).  The parallel line will have the same slope.

y = (9/4)x + b

We can find a value of b that would shift this line to include (4,7) by using this point in the equation:

y = (9/4)x + b

7 = (9/4)(4) + b

7  = 9 + b

b = 2

The equation of a line parallel to the reference line is y = (9/4)x + 2

Step-by-step explanation:

Answer:

Circumference = 62.84 cm

Step-by-step explanation:

Circumference = 2πR

Radius = 10 cm

π = 3.142

Circumference = 2 * 3.142 * 10

Circumference = 62.84 cm

Answer:

B. - 3,000 because descending means going down

Answer:

(x+1) ( x+(1/2))

Step-by-step explanation:

6x² +9x +3  , divide all terms by 6 to have the first term with coefficient 1

x² + (9/6)x + (3/6) , simplify the fractions

x² + (3/2)x + (1/2)

To get x² the first term we should have

(x.....)(x.....)

To get the last term (1/2) we should have

(x...1)(x...(1/2))

To get the middle term (3/2)x we should have

+1*x +(1/2)  x = (2/2)x +(1/2)x = (3/2)x

(x+1) ( x+(1/2))

Let's find out

37 and g more means addition

305 increased by f means also addition

Answer:

X² - 9x + 18

Step-by-step explanation:

x • x

x²

x • -6

-6x

-3 • x

-3x

-3 • -6

18

combine like terms

x² - 6x - 3x + 18

-6x - 3x= -9x

x²-9x+18

(a) The interior angles of any triangle sum to 180° in measure. So

(8x + 2) + 70 + 60 = 180

Solve for x :

8x + 132 = 180

8x = 48

x = 6

(b) Evaluate 8x + 2 when x = 6 :

8•6 + 2 = 48 + 2 = 50

Answer:

A) Perimeter of the blanket = 2(Length + Width)
<=> 2[(3x - 7) + (2x - 3)]

<=> 2(3x - 7 + 2x - 3)
<=> 2(5x - 10)

<=> 10x - 20

B) Area of the blanket = Length * Width

<=> (3x - 7)(2x - 3)

<=> [tex]6x^{2}[/tex] - 9x - 14x + 21
<=> [tex]6x^{2}[/tex] - 23x + 21

C) Difference between the areas of the two blankets = (L1 * W1) - (L2 * W2)

<=> [(3x - 7)(2x - 3)] - [(2x + 10)(4x - 10)]

<=> (6[tex]x^{2}[/tex] - 23x + 21) - (8[tex]x^{2}[/tex] - 20x + 40x - 100)

<=> 6[tex]x^{2}[/tex] - 23x + 21 - 8[tex]x^{2}[/tex] + 20x - 40x + 100

<=> -2[tex]x^{2}[/tex] - 43x + 121

Hope it helps you!

Answer:

2/3 length and 3/4 width!

Step-by-step explanation:

I had this same question :D

Answer:

Between 2 1/2 and 3 ounces

Step-by-step explanation:

Since 1/3 is lower than 3/4, 5 1/3 - 2 3/4 must be lower than 3, but higher than 2.

So, we can eliminate C and D.

A's range is too small, so we can select B.

x=root[3]{-1.500}=-1.14471

Answer:

f(x) = 2x+5

Step-by-step explanation:

As you know, a student ticket is one item, and you only need one of these to enter a football game. We will assume he is by himself and without friends. There are items he can buy for $2 each at the concession stand.

With what we know, we can conclude that the total cost to attend the football game could be a function.

The function will be

f(x) = 2x + 5

This is because you buy the ticket one time and buys x items, which is modeled by the function.

I'm sorry that I can't send any links, but if you go to desmos graphing calculator, you can find type the function out and get the graph of the function. Remember to look only at the first quadrant!

Your welcome for the answer, and comment if you have any questions! If you could mark this answer as the brainliest, I would greatly appreciate it! :D

Answer:

First we must use the property of the sum of perfect squares:

X^2 -14x +y^2 +10y+65 =0

Adding 7^2 and -7^2

x^2 -14x+7^2-7^2 +y^2+10y+65=0

x^2 -2.7x +7^2 -49 +y^2+10y+65=0

(X-7)^2 +y^2+10y+16=0

Adding 5^2 and -5^2

(X-7)^2 +y^2 +10y+5^2-5^2+16=0

(X-7)^2 +y^2+2.5y+5^2 -25 +16=0

(X-7)^2+ (y+5)^2 -9 = 0

(X-7)^2 +(y+5)^2 = 9

(X-7)^2+(y+5)^2 = 3^2

Center = (7, -5)

R = 3

The circle is in the 4 quadrant.

Answer:

x= 47°

Step-by-step explanation:

My answer is 67° to confirm it lol

Answer:

the last one is the answer

Answer:

Step-by-step explanation:

1) The radius of circle is 4cm

The area of the circle is

[tex]\pi ^{2}[/tex]

[tex]\frac{22}{7} *4*4\\[/tex]

[tex]\frac{22}{7} *16=50.24cm^{2}[/tex]

2)

Circumference of the circle = [tex]\pi d[/tex]

Circumference of the circle = 3.14 * 10

Circumference of the circle = 31.4 inches

Answer:

[tex]=31.5[/tex]

Step-by-step explanation:

Given the following question:

75% of 42

In order to find the answer, we use the formula to calculate percentage.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{75\times42}{100} =75\times42=3150\div100=31.5[/tex]
[tex]=31.5[/tex]

Which means 75% of 42 is "31.5."

Hope this helps.
