Find the domain for the expression:
y/y-5 + 1/y+8
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]
→[tex] \frac{(1 - 4y) + 8 \: • \: y}{y} = \frac{4y + 1}{y} [/tex]

Solve for a.
5a−12=3
Enter your answer in the box.
a =
[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:
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.

square. If the distance
between bases is 60 feet,
Find the diagonal distance
From third base to First
base
1-84.9
2-11.9
3-12.5
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
Find x to the nearest tenth.
8
6
X
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.
In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 3/4 of the drink is apple juice and 1/10 is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form.
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.

Kyle types college reports for $1.70 per page. He also charges $6 to cover the cost of supplies. How many pages did he write if he charged $40.00? Write and solve an equation.
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.

Question 1 (5 points)
Dilate the rectangle below by a scale factor of 2. If the current side lengths are 15
and 8, what are the side lengths on the new dilated rectangle?
In your answer, give the new side lengths for the dilated image and explain how you
calculated them.
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.

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
