Answer:

1/y+4

Step-by-step explanation:

1-5+1/y+8

1/y+(1-5+8)

1/y+4

[tex] \frac{y}{y} - 5 + \frac{1}{y} + 8 [/tex]

→[tex](1 - 5) + \frac{1}{y} + 8[/tex]

→[tex]-4 = \frac{ - 4}{1} = \frac{ - 4 \: • \: y}{y} [/tex]

→[tex] \frac{ - 4 \: • \: y + 1}{y} = \frac{1 - 4y}{y} [/tex]

→[tex] \frac{(1 - 4y)}{y} + 8[/tex]

→[tex]8 = \frac{8}{1} = \frac{8 \: • \: y}{y} [/tex]

Answer:

D

Step-by-step explanation:

D

0 is the y intercept and -4 is the slope.

Answer:

D. y = -4x

Step-by-step explanation:

First, find the slope:

m = (-8 - 0) / (2 - 0)

[tex]m = -\frac{8}{2}[/tex]

Use slope-intercept form:

[tex]y = -\frac{8}{2}x[/tex]

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

Answer:

112 sq cm

Step-by-step explanation:

Area of the square:

A = s^2

= 8^2

=64 sq cm

Area of a triangle:

A = 1/2•b•h

= 1/2•8•12

= 48 sq cm

Area of total shape:

A_square + A_triangle

= 64 + 48

= 112 sq cm

Answer:

cone A= 20.9×5=104.5

cone B= 5×4=20

20×20.9=418

cone B -cone A = -313.5

Step-by-step explanation:

area of the trapezoid = area of the 2 triangles +

area of the rectangle

i) area of triangle on left:

a = ½ bh

a = ½ × 2 × 9

a = 9 in²

ii) area of triangle on right:

a = ½ bh

a = ½ × 2 × 9

a = 9 in²

iii) area of rectangle = length × width

a = l × w

a = 12 × 9

a = 108 in²

iv) area of trapezoid = 9 + 9 + 108

= 126 in²

Answer:

15/20 : 2/20 : 3/20 or you could put 3/4 : 1/10 : 3/20 but that's up to your teacher

Step-by-step explanation:

We know that there are 3 ingredients.

3/4 apple juice

1/10 orange juice

We want to know how much cranberry juice to apple juice to orange juice.

First, let's start with getting common denominators.

The LCD (least common denominator) between these two fractions is 40. (4 * 10)

So:

3/4 * 10/10  = 30/40

1/10 * 4/4 = 4/40

Now we know them with equal denominators. Now let's subtract them from the whole (40/40) to find out how much cranberry juice.

40/40 - 30/40 - 4/40 = 6/40

Cranberry juice = 6/40 of the whole.

Now we can find the ratio in its simplest form.

30/40 : 4/40 : 6/40

Can we simplify these fractions? yes.

The can all be simplified by 2

15/20 : 2/20 : 3/20

Since 2 can't be simplified by anything but 2 or 1, and 15 and 3 cannot be simplified by 2, this is your answer.

or you could put 3/4 : 1/10 : 3/20 but that's up to your teacher.

Answer:

the correct answer should be c

Answer:

AB and CD would be 30

AC and BD would be 16

Step-by-step explanation:

The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.

Answer:

Answer:

They are Vertical angles, and it is 67 degrees

Step-by-step explanation:

Answer:

neither a or b

Step-by-step explanation:

a function has to have each X have a Y

a domain is paired with exactly one range value.

it has to pass the vertical line test

independent variable is X

dependant variable is Y

student name = x

colors/teachers is Y

so since there is the chance the students can have the same teacher and/or favorite color. then it is not a function

Answer:

4(5x+4)

Step-by-step explanation:

The factors of 16 are: 1, 2, 4, 8, 16

The factors of 20 are: 1, 2, 4, 5, 10, 20x

Then the greatest common factor is 4.

Answer:

x ≈ 5.3

Step-by-step explanation:

a²+b²=c²

c is always the hypotenuse in a right angle triangle.

6² + x² = 8²

36 + x² = 64

64 - 36 = 28

x² = 28

x = √28

Use calculator from here.

√28 = 5.29150262213

5.29150262213 ≈ 5.3

Because the number after 2, which is 9, is greater than 5, the nearest tenth is 5.3, not 5.2.

Answer:

2) D

because:

[tex] \frac{9}{1} \times 4 \\ 9 \times 4 \\ 36 \: is \: not \: equal \: to \: 4[/tex]

4) B

because:

[tex] \frac{5}{5} \times 8 \\ 1 \times 8 \\ 8 \: is \: equal \: to \: 8[/tex]

[tex]5a - 12 = 3 \\ 5a = 3 + 12 \\ 5a = 15 \\ a = \frac{15}{5} \\ a = 3[/tex]

Answer:

[tex]a=3[/tex]

Step-by-step explanation:

Given the following question:

[tex]5a-12=3[/tex]

To solve this equation, we need to add 12 on both sides and then isolate the variable for a.

[tex]5a-12=3[/tex]
[tex]-12+12=0[/tex]
[tex]12+3=15[/tex]
[tex]5a=15[/tex]
[tex]\frac{5a}{5} =\div5[/tex]
[tex]15\div5=3[/tex]
[tex]a=3[/tex]

Answer:

$1.70p + $6 = $40.00

Step-by-step explanation:

$1.70p + $6 - $6 = $40.00 - $6

$1.70p = $34.00

$1.70p ÷ 1.70 = $34.00 ÷ 1.70

p = 20

He wrote 20 pages.

Answer:

84.9

Step-by-step explanation:

The distance between first and third base makes the hypotonus of a triangle where the lengths of the legs are each 60 feet. To find the hypotonus, add (60)^2 + (60)^2 to get 3600 +3600 = 7200. Then square root 7200 to get the distance between first and third as 84.9

Answer:

6.4 = b     and     7.8 = a

Step-by-step explanation:

Using the formula:

a^2 + b^2 = c^2

we can find the length of b

for the first triangle

now we just plug in the lengths.

5^2 + 4^2 = b^2

simplify into :

25 + 16 = b^2

add

41 = b^2

now in order to get rid of the ^2, we just find the square root of 41.

√41 ≈ 6.4

6.4 = b

Now we just need to solve for A

since we know

a^2 + b^2 = c^2 that must mean

c^2 - b^2 = a^2

so this is the formula we will be using.

now we just plug in the lengths of the second triangle into this equation.

10.5^2 - 7^2 = a^2

simplifies into

110.25 - 49 = a^2

subtract

61.25 = a^2

now we just find the square root of 61.25.

√61.25 = 7.8

7.8 = a

you can check this by putting it back in the formula

a^2 + b^2 = c^2

I will do this quickly (only for the second triangle)

we know

a = 7.8

b = 7

c = 10.5

7.8^2 + 7^2 = 10.5^2

simplifys into

60.84 + 49 = 110.25

60.84 + 49 ≈ 110

110.25 ≈ 110

110 = 110

which proves that this is correct.
