Is (1, 10) a solution to this system of inequalities?
y > X + 9
y > 10
Answer:
No
Step-by-step explanation:
If (1, 10) is a solution to the system then it must satisfy both inequalities.
Using x = 1 and y = 10 , then
10 > 1 + 9 , that is
10 > 10 ← False
and
10 > 10 ← False
Neither of the inequalities are satisfied by (1, 10)
Thus it is not a solution
If ∠WOZ and ∠WOX are supplementary angles and ∠WOX and ∠XOY are complementary angles, then what is the value of x and m∠XOY?
A.
x = 6; m∠XOY = 20°
B.
x = 18; m∠XOY = 6°
C.
x = 20; m∠XOY = 6°
D.
x = 6; m∠XOY = 18°
Answer:
D.x = 6; m∠XOY = 18°
Step-by-step explanation:
Supplementary angles add to 180 and complementary angles add to 90
∠WOZ + ∠WOX = 180
108 + ∠WOX = 180
∠WOX + ∠XOY = 90
∠WOX + 3x = 90
∠WOX = 90 -3x
Replace WOX in the first equation
108 + ∠WOX = 180
108 + 90 -3x = 180
Combine like terms
198 -3x = 180
Subtract 198 from each side
-3x = 180-198
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
∠XOY = 3x = 3*6 = 18

Answer:
66 = ∠JKN
Step-by-step explanation:
∠JKM = 99
∠LKM = 66
KN bisects means middle point divides into two equal parts
so first lets find ∠LKN and ∠NKM
66/2 = ∠LKN and ∠NKM each
33 = ∠LKN
33 = ∠NKM
so if we add ∠JKL + ∠LKN + ∠NKM = 99
∠JKL + ∠LKN + ∠NKM = 99
∠JKL + 33 + 33 = 99
∠JKL + 66 = 99
∠JKL = 99-66
∠JKL = 33
now to find ∠JKN we must add
∠JKL + ∠LKN = ∠JKN
33 + 33 = ∠JKN
66 = ∠JKN
Kenya plans to make a down payment plus monthly payments in order to buy a
motorcycle. At one dealer she would pay $2,250 down and $200 each month. At
another dealer, she would pay $2,850 down and $175 each month. After how
many months would the total amount paid be the same for both dealers? What
would that amount be?
After
months Kenya will have paid $
for the bike at either dealer.
Answer:
Step-by-step explanation:
2500+150x=3000+125x
150x-125x=3000-2500
25x=500
x=500/25
x=20 mo
----------------
2500+150*20=3000+125*20
5500=5500 total paid after twenty months

pat has no more then 20 sweets. she counts her sweets by twos she has one sweet left. then she counts by five. she has 2 left over. how many sweets could she have
Answer:
She can either have 7 sweets or 17 sweets.
Step-by-step explanation:
Variable x = number of sweets Pat has
x < 20
Counting by 5's (5, 10, 15) that will result in 2 left over (5 + 2, 10 + 2, and 15 + 2). This leaves 3 possible options as to how many sweets Pat has: 7, 12, and 17.
Counting by 2's (2, 4, 6 . . . 18) that will result in 1 left over (6 + 1, 10 + 1, 16 + 1) This leaves 2 possible options, given the other numbers from counting by 5's were eliminated.: 7 and 17.
An alloy that is 30% silver is mixed with 200 g of a
10% silver alloy. How much of the 30% alloy must
be used to obtain an alloy that is 24% silver?
show work plz
Answer:
The answer is [tex]466\frac{2}{3}\,g[/tex]
Step-by-step explanation:
Let,
Amount of alloy with 30% silver = x g
Given,
Amount of alloy with 10% silver = 200 g
So, Total Amount of alloy with 24% silver = (x+200) g
Now,
[tex]x*0.30+200*0.10=(x+200)*0.24\\=>0.30x+20=0.24x+48\\=>0.06x=28\\x=466\frac{2}{3}\,g=466.67\,g[/tex]

Half the difference of a number n and 20 is 30. What is the number?
Answer:
80Step-by-step explanation:
Half the difference of a number n and 20 ⇒ (n - 20)/2... is 30 ⇒ = 30Solve the equation for n:
(n - 20)/2 = 30n - 20 = 30*2n - 20 = 60n = 60 + 20n = 80The number is 80
Answer:
Number is 40
Step-by-step explanation:
Let the number be n
(n - 20)/2 = 30
(n - 20) = 2 × 30
n = (2 × 30) + 20
n = 60 + 20
n = 80

Answer:
#4Let M is the midpoint of DE.
Since D is at 8 and DE = 5.
DM = ME = 5/2 = 2.5
Point M is at:
8 + 2.5 = 10.5 if E is to the right of D8 - 2.5 = 5.5 if E is to the left of D#5Given
XY = 7, YZ = 2x - 1, XZ = 30Since XZ = XY + YZ, set up an equation and solve for x:

here is the table of values for y = f(x)
x -2 , -1 , 0, 1, 2 , 3, 4 , 5, 6
f(x) 5, 6, 7, 8, 9, 10, 11, 12, 13
mark the statements that are true
A. f (-1) =6
B. f (5) = - 2
C. The domain for (x) is the set (-2, -1, 0, 1 , 2, 3, 4, 5, 6
D. the range for f(x) is all real numbers
Answer:
A and C
Step-by-step explanation:
A
From the table the value of f(x) when x = - 1 is 6
Thus f(- 1) = 6 ← is true
B
From the table the value of f(x) when x = 5 is 12
Thus f(5) = - 2 ← is false
C
The domain is the values of x from the table ( the input values )
domain is { - 2, - 1, 0, 1, 2, 3, 4, 5, 6 } ← is true
D
The range is the values of f(x) from the table ( the output values
range is { 5, 6, 7, 8, 9, 10, 11, 12, 13 }
The range for f(x) is all real values ← is false

Can someone solve/walk me through this problem please?
-6x+5y=34
-6x-10y=4
Answer: x = -4
y = 2
Step-by-step explanation:
From equation I
-6x + 5y = 34
-6x = 34-5y
-(-6x) = -(34-5y)
or, 6x = 5y-34
or, x = 5y-34/6
so
substituting the value in equation II
-6x-10y = 4
or, -6{(5y-34)/6} - 10y = 4
or, -(5y-34)-10y = 4
or, -5y + 34-10y = 4
or, -15y = -30
or, y = -30/(-15)
so, y = 30/15
so, y = 2
now
x = (5y-34)/6
= (5*2-34)/6
= (10-34)/6
= -24/6
= -4
Answer:
x=-4, y=2
Step-by-step explanation:
-6x-10y=4
-6x=4+10y
(4+10y)+5y=34
15y=30
y=2
-6x-10(2)=4
-6x=24
x=-4
