What is the slope of y= -x +7?

Answer:

width:6, length:18

Step-by-step explanation:

You can subsititue width with x.

The length would then be 2x+6.

The value of width and length combined is 24.

The equation would be (2x+6)+(x)=24

Simplify to 3x+6=24

Subtract 6 from both sides giving 3x=18

Simplify to x=6

There's the width. Now you can substitute to find the length.

(6x2)+6=18

I hope this is right.

Answer:

520,800

Step-by-step explanation:

Answer: 23%

Step-by-step explanation:

From the question, we are informed that a new pair of shoes cost $78 and that they are on sale for $60.06.

The percent of change will be calculated as:

Change/ Cost price × 100

= [(78 - 60.06) / 78] × 100

= (17.94 / 78) × 100

= 0.23 × 100

= 23%

Answer:

8/15

Step-by-step explanation:

you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1

then you multiply across

2/15 * 4/1

you first multiply 2 and 4 and your answer will be 8 which is the numerator

then multiply 15 and 1 which is 15, the denominator

then you get

8/15

Answer:

A. y = 2[tex](x - 2)^{2}[/tex] + 5

Step-by-step explanation:

positive 2 because the parabola faces upwards, and + 5 because it's vertex is places at (2,5)

Answer:

The 2 integers would be: 2 and 8

Step-by-step explanation:

2 + 8 = 10

Reciprocal of 2: 1/2

Reciprocal of 8: 1/8

1 / 2 - 1 / 8 = 4/8 - 1/8 = 3/8

Answer:

Using the y=mx+b formula: -6/5

Step-by-step explanation:

6x + 5y = -5

5y = -6x -5

y = -6/5x -1

The slope would be -6/5, meaning the line would travel 5 to the right and 6 down, starting from the coordinate 0, -1.

Hope I helped.

Answer:

0,1/13,49/100,1/2,11/20,8/9,1

Step-by-step explanation:

Answer:

x = 13

Step-by-step explanation:

the angles are equal.

8x + 2 = 14x - 76

subtract 8x from both sides

8x - 8x + 2 = 14x - 8x - 76

2 = 14x - 8x - 76

2 = 6x - 76

add 76 to both sides

2 + 76 = 6x - 76 + 76

2 + 76 = 6x

78 = 6x

divide both sides by 6

78/6 = 6x/6

78/6 = x

13 = x

Answer:

34;34;112

Step-by-step explanation:

It's a Isosceles triangle so the equation is

x+17=4x-34

x-4x=-35-17

-3x=-51

x=-51/-3

x=17

17+17=34

4.17-34=34

6.17+10=112

Answer:

b; 78: 51: 51:

Step-by-step explanation:

i gotchu, u can solve without solving, by procces of elimination, none of the angles in the triangle are higher than 90 degrees, so it cant be a or d (they both have angles above 100 degrees) and to get the final answer, they arent the same length, eliminating c. the answer is b

Step-by-step explanation:

Coprime numbers:

A Co-prime number is a set of numbers or integers which have only 1 as their common factor.

For eg: (2,3), (11,12), (99,100) and so on; they have 1 as their HCF. The sum of any two coprime numbers is always coprime with the product of the same two coprime numbers. For eg: The sum of 2 and 3 is 5 and the product of 2 and 3 is 6. Hence, 5 and 6 are coprime numbers.

Prime number

A number that can be divided exactly only by itself and 1, for example 7, 17 and 41

The unit rate is .6¢

Step-by-step explanation:

To find unit rate, you divide the price by the amount of whatever it is that there are. In this case its cans of beans. So it would by 9.60 divided by 16 which equals .6.

Answer:

D. -3r^2 + 11r + 9

Step-by-step explanation:

8r + 4r^2 + 3r + 9 - 7r^2

shift somethings around so it's easier to tell

4r^2 - 7r^2 + 8r + 3r + 9

simplify/add

-3r^2 + 11r + 9

Answer:

vertex = ( - [tex]\frac{3}{2}[/tex],  [tex]\frac{75}{4}[/tex] )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

Given

y = - 3(x - 1)(x + 4) ← expand the factors using FOIL

  = - 3(x² + 3x - 4) ← distribute parenthesis by - 3

  = - 3x² - 9x + 12 ← in standard form

with a = - 3 and b = - 9 , thus

[tex]x_{vertex}[/tex] = - [tex]\frac{-9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]

Substitute this value into the equation for corresponding value of y

y = - 3( - [tex]\frac{3}{2}[/tex] - 1)( - [tex]\frac{3}{2}[/tex] + 4)

  = - 3 × - [tex]\frac{5}{2}[/tex] × [tex]\frac{5}{2}[/tex]

  = - 3 × - [tex]\frac{25}{4}[/tex]

  =  [tex]\frac{75}{4}[/tex]

Thus

vertex = ( - [tex]\frac{3}{2}[/tex], [tex]\frac{75}{4}[/tex] )

Step-by-step explanation:

Answer:

6.  y = [tex]\frac{11}{6}[/tex]x + 14

7.  y + 2 = [tex]\frac{-11}{12}[/tex](x-8)   or    y - 9 = [tex]\frac{-11}{12}[/tex](x+4)

8.  y = 0x + 236   or y = 236

Step-by-step explanation:

point slope form: y-[tex]y_{1}[/tex] = slope * (x-[tex]x_{1}[/tex])

* [tex]y_{1}[/tex] is the y value of a certain point

* [tex]x_{1}[/tex] is the x value of a certain point

slope intercept form: y=mx+b

*m is the slope

*b is the y-intercept

Answer:

26.5

Step-by-step explanation:

if you see the picture, just by counting we know that:

triangle 1

[tex]b=3\\\\h=3\\\\A_1=\frac{3*3}{2}=4.5[/tex]

triangle 2

[tex]b=2\\\\h=2\\\\A_2=\frac{2*2}{2}=2[/tex]

rectangle 3

[tex]b=5\\\\h=4\\\\A_3=5*4=20[/tex]

the total area is

[tex]A_T=A_1+A_2+A_3\\\\=4.5+2+20=26.5[/tex]

Answer:

26.5

Step-by-step explanation:

Make the shape into 2 triangles and 1 rectangle

Triangle 1

b = 3

h = 3

3 x 3 /2 = 4.5 ( divide 3x3 which is 9 by 2)

Triangle 2

b = 2

h = 2

2 x 2 /2 = 2 ( divide 2x2 which is 4 by 2)

Rectangle

b = 5

h =4

5 x 4 = 20

( the rectangle isn't divided by 2)

4.5 + 2 = 20 = 26.5 (Add all the areas)
