how do you solve y=3-x
2x+y=6
Answer:
x=3 y=0
Step-by-step explanation:
This is called system of innequalities
we know y= 3-x and we substitute that into 2x+y=6 and we get
2x+3-x=6 we solve and get x=3
then we substitute x into the first equation and we get y=3-3 and get 0
x=3 y=0
3x + 16 = 136
(3 seconds per item, plus 16 seconds to process payment, equals 136 seconds total.)
Subtract 16 from each side. Then divide both sides by 3.

Soos is spending money at an average rate of $5 per day. After 9 days, he has $25 left.
How much money did Soos have at the beginning (on day 0)?
y - 5= 9(x - 25)
Answer:
$70
Step-by-step explanation:
According to the problem, calculation of given data are as follows:
Spending money at rate = $5 per day
After 9 days money left = $25
We can calculate the money on day 0 by using following formula,
y = mx + b
Here, y = money left after 9 days
m = rate of spending money
x = number of days
b = money on day 0
So, by putting value, we get
$25 = (-5 × 9 ) + b
b = $25 + $45
= $70

Mae has a number cube with 6 sides that are numbered 1 through 6. What is the probability that Mae will roll an odd number?
A
1 out of 3
B
1 out of 6
с
3 out of 6
D
5 out of 6
Answer:
C) [tex]P(E) = \frac{3}{6}[/tex]
The probability that Mae will roll an odd number
[tex]P(E) = \frac{3}{6}[/tex]
Step-by-step explanation:
Step(i):-
Given that Mae has a number cube with 6 sides that are numbered 1 through 6.
n(S) = { 1,2,3,4,5,6,} = 6
Let 'E ' be the event of odd numbers
Mae will roll an odd number
n(E) = {1, 3, 5} = 3
Step(ii):-
The probability that Mae will roll an odd number
[tex]P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}[/tex]
[tex]P(E) = \frac{3}{6}[/tex]

What is x?
4x(2x+6)=8x²(23-5)
pls, help for the first person to answer I will give them a brainlist.
Answer:
x= 3/17
Step-by-step explanation:
4x(2x+6) =8x^2(23-5)
8x^2 +24x = 144 x^2
24x = 136 x^2
24= 136 x
x=24/136
x=3/17

[tex]5x {}^{2} + 2x - 3 - px - p[/tex]
Answer:
5x² + 2x - 3 - px - p
= 5x² + 5x - 3x - 3 - p(x + 1)
= 5x(x + 1) - 3(x + 1) - p(x + 1)
= (x + 1)(5x - 3 - p)

Find the measure of each interior angle.
Answer:
d) m<J = 115, m<K = 130, m<M = 50, m<N = 65
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 360
if we add all the given angles 7x + 10 = 360 subtract 10 from both sides
7x = 350 divide both sides by 7
x = 50 to find the measure of each angle replace x with 50

Which value of y makes the inequality 3y^2+2(y-5)>8 true
A y=0
B y= -1
C y= -2
D y= -3
Answer:
Conclusion:
As y = -3 MAKES the inequality TRUE.
Therefore, option D i.e. y = -3 is true.
Step-by-step explanation:
Given the inequality
3y² + 2(y - 5) > 8
For y = 0
substitute y = 0 in the inequality
3y² + 2(y - 5) > 8
3(0)² + 2(0 - 5) > 8
3(0) + 2(-5) > 8
0 - 10 > 8
-10 > 8
FALSE!
-10 can not be greater than 8.
Hence, y = 0 does not make the inequality true.
For y = -1
substitute y = -1 in the inequality
3y² + 2(y - 5) > 8
3(-1)² + 2(-1 - 5) > 8
3(1) + 2(-6) > 8
3 - 12 > 8
-9 > 8
FALSE!
-9 can not be greater than 8.
Hence, y = 1 does not make the inequality true.
For y = -2
substitute y = -2 in the inequality
3y² + 2(y - 5) > 8
3(-2)² + 2(-2 - 5) > 8
3(4) + 2(-7) > 8
12 - 14 > 8
-2 > 8
FALSE!
-2 can not be greater than 8.
Hence, y = -2 does not make the inequality true.
For y = -3
substitute y = -3 in the inequality
3y² + 2(y - 5) > 8
3(-3)² + 2(-3 - 5) > 8
3(9) + 2(-8) > 8
27 - 16 > 8
11 > 8
TRUE!
11 is indeed greater than 8.
Hence, y = -3 MAKES the inequality TRUE.
Conclusion:
As y = -3 MAKES the inequality TRUE.
Therefore, option D i.e. y = -3 is true.

D
Step-by-step explanation:
An ice cream shop is choosing a milk delivery service. The Spotted Cow charges $2.80 per gallon, plus a $2 delivery fee. Dairy Farms charges $2.10 per gallon, plus a $10 delivery fee. If the ice cream shop uses 20 gallons a milk per week, which service is a better deal? Group of answer choices
Answer:
The Dairy Farm is better deal.
Step-by-step explanation:
Given that:
Per gallon charges of the Spotted Cow = $2.80
Delivery fee = $2
Let,
x be the gallons of milk.
S(x) = 2.80x + 2
Putting x = 20
S(20) = 2.80(20) + 2 = 56 + 2
S(20) = $58
Per gallon charges of the Dairy Farms = $2.10
Delivery fee = $10
D(x) = 2.10x + 10
Putting x = 20
D(20) = 2.10(20) + 10 = 42 + 10
D(20) = $52
Hence,
The Dairy Farm is better deal.

Find the length of the hypotenuse, c in this triangle
Answer:
c = 5cm
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 3^2 = c^2
16 + 9 = c^2
25 = c^2
do the square root of 25 and c to solve for c
the square root of c^2 is c
therefore, c= 5cm
