Answer:
y < 10 or (10, -∞)
Step-by-step explanation:
7y + 1 > 8y - 9
Simply get the y's on the right by subtracting 7y from both sides:
1 > y - 9
then adding 9 to both sides:
y < 10
or in interval notation:
(10, -∞)

Answer:
∠1 = 28°
Step-by-step explanation:
A rhombus is a quadrilateral with four sides of equal length.The sum of the interior angles of a quadrilateral (rhombus) = 360°The opposite interior angles of rhombuses are congruent (the same).Diagonals cut each interior angle equally. So in the diagram, ∠1 = ∠2 and ∠3 = ∠4 therefore, ∠1 = ∠2 = ∠3 = ∠4Therefore, to calculate ∠1 subtract 124° twice from 360° then divide the answer by 4:
∠1 = [360 - (124 x 2)] ÷4
= [(360 - 248) ÷ 4]
= 112 ÷ 4
= 28°
Find the perimeter.
Write your answer as a fraction, whole number, or mixed number
Answer:
Well, first you'll have to do P (perimeter) = 2(a + b)
So: P= 2(68/15 + 32/5)*
P = 2(68/15 + 96/15)
P = 2(164/15)
Then, do the equation:
328/15

what is the value of y?
Answer:
y=6
Step-by-step explanation:
Since this is a rhombus, the 4 triangles must have the same base and height. They are also all right triangles, and we are given the hypotenuse (x+5) and (2x). They each must be equal, so we can form the equation x+5=2x to solve for one of them:x=5. So one of the legs is y, the other is 8, and the hypotenuse is 5+5=10. We can use the pythagorean theorem to solve: y^2+8^2=10^2.
y^2+64=100
y^2=100-64=36.
y=6.

When you add the same signs, find the ____ and ____ .
Answer: the absolute values and give the answer the same sign
Step-by-step explanation:
In the figure below, N lies between M and P.
Find the location of N so that the ratio of MN to NP is 4 to 5 .
[tex] \frac{MN}{NP} = \frac{4}{5} \\ [/tex]
[tex]MP = 26 - 8[/tex]
[tex]MP = 18[/tex]
[tex]MP \div (4 + 5) = 18 \div (4 + 5)[/tex]
[tex] \frac{MP}{9} = \frac{18}{9} \\ [/tex]
[tex] \frac{MP}{9} = 2 \\ [/tex]
Thus;
[tex]MN = 2 \times 4[/tex]
[tex]MN = 8[/tex]
and
[tex]NP = 2 \times 5[/tex]
[tex]NP = 10[/tex]
So the location of N is :
[tex]N = 8 + 8 \: \: or \: \: N = 26 - 10[/tex]
[tex]N = 16[/tex]

Enter your answer as: m,n
Answer:
m = 2
n = 4
Step-by-step explanation:
if the two triangles are congruent then:
5m + 1 = 11 and 8m - 2n = 2m + n
Solving 5m + 1 = 11 to find m:
Subtract 1 from both sides: 5m = 10
Divide both sides by 5: m = 2
Now substitute found value for m into 8m - 2n = 2m + n and solve for n:
8(2) - 2n = 2(2) + n
16 - 2n = 4 + n
12 = 3n
4 = n

describe the values of c for which the equation has no solution. explain your reasoning.
|x-7|=c
Answer:
c=|x-7|
Step-by-step explanation:
The values of "c" for which the equation |x - 7| = c has no solution are any values of "c" that are less than or equal to zero.
The equation |x - 7| = c represents the absolute value of the difference between x and 7, which is equal to the constant "c."
For an absolute value equation like this, there are two cases to consider:
When (x - 7) is nonnegative (or zero): In this case, the absolute value of (x - 7) is just (x - 7) itself. So the equation becomes:
x - 7 = c
When (x - 7) is negative: In this case, the absolute value of (x - 7) is the negative of (x - 7). So the equation becomes:
-(x - 7) = c
-x + 7 = c
Now let's analyze these cases to determine the values of "c" for which the equation has no solution:
Case 1: x - 7 = c
If "c" is positive, then we can solve for "x":
x = c + 7
This solution is valid for all values of "c" because it provides a real solution for any positive "c."
Case 2: -x + 7 = c
If "c" is positive, we can solve for "x":
x = 7 - c
This solution is valid for all values of "c" because it provides a real solution for any positive "c." positive value of "c" will have a valid solution. However, if "c" is negative or zero, then there is no real value of "x" that satisfies the equation. This is because the absolute value of a real number is always nonnegative, so if "c" is negative or zero, there is no real value of "x" that can make |x - 7| equal to a negative or zero "c."

Find two numbers whose difference is 8 but whose average is 13.
Answer:
9 and 17
Step-by-step explanation:
Let the two numbers by x and y.
We are told that x - y = 8
And we learn that (x+y)/2 = 13
Rearrange the first equation to isolate x (or y):
x - y = 8
x = 8+y
Use this expression for x in the second equation:
(x+y)/2 = 13
((8+y)+y)/2 = 13
Solve for y:
(2y+8)/2 = 13
y + 4 = 13
y = 9
If y = 9, x is:
x - y = 8
x - (9) = 8
x = 17
The difference between 17 and 9 is 8
The average is (9+17)/2 = 13
Answer:
9 and 17
Step-by-step explanation:
let x and y be the 2 numbers , x > y , then
x - y = 8 → (1)
[tex]\frac{x+y}{2}[/tex] = 13 ( multiply both sides by 2 )
x + y = 26 → (2)
add both equations term by term to eliminate y
2x + 0 = 34
2x = 34 ( divide both sides by 2 )
x = 17
substitute x = 17 into (1) and solve for y
17 - y = 8 ( subtract 17 from both sides )
- y = - 9 ( multiply both sides by - 1 )
y = 9
The 2 numbers are 9 and 17
