Choose the statement that best describes a solution of a system of linear inequalities.(1 point)
A solution of a system of linear inequalities is an ordered pair that satisfies at least one of the inequalities in the system.
A solution of a system of linear inequalities is an ordered pair that satisfies the intersection of the border of each inequality.
A solution of a system of linear inequalities is an ordered pair that satisfies neither inequality in the system.
A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Answer: A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Step-by-step explanation:
A system of linear inequalities can be written as:
y < a*x + b
y < c*x + d
or
y ≤ a*x + b
y ≤ c*x + d
In the first case, the borders are not included in the solutions, and in the second case, the borders are included.
Where the solutions will be points like (x, y), where these points must be solutions for both inequalities.
Then the only option that is correct for a general system of inequalities is:
A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.
Answer:
A solution of a system of linear inequalities is an ordered pair that satisfies at least one of the inequalities in the system.A solution of a system of linear inequalities is an ordered pair that satisfies the intersection of the border of each inequality.A solution of a system of linear inequalities is an ordered pair that satisfies neither inequality in the system.A solution of a system of linear inequalities is an ordered pair that satisfies each inequality in the system.

#1: Solve the linear system below using the elimination method. Type your
answer as an ordered pair in the form (#,#).*
2x + 5y = -16
-3x + 7y = -5
Answer:
[tex](-3,-2)[/tex]
Step-by-step explanation:
First, you need to get one like term in each equation the same in order to eliminate. To do less damage to the equation, we'll use the x terms.
To get the x terms the same, multiply both equations by the opposite x term:
[tex]-3(2x+5y)=-3(-16)\\\\2(-3x+7y)=2(-5)[/tex]
Simplify by multiplying. Use the distributive property for the left side (remember, two negatives make a positive and a negative multiplied by a positive will always be negative):
[tex]-3(2x)-3(5y)=-3(-16)\\\\2(-3x)+2(7y)=2(-15)\\\\\\-6x-15y=48\\\\-6x+14y=-10[/tex]
Now subtract all like terms. The x terms cancel out:
[tex]-6x-(-6x)=0\\\\-15y-14y=-29y\\\\48-(-10)=58\\\\-29y=58[/tex]
Now solve the new equation for y. Isolate the variable by using inverse operations. The term can be seen as -29×y. In order to isolate the variable, use division (opposite of multiplication). Divide both sides by 29:
[tex]\frac{-29y}{29} =\frac{58}{29} \\\\-1y=2[/tex]
Make the variable positive. Multiply both sides by -1:
[tex]-1(-1y)=-1(2)\\\\y=-2[/tex]
The value of y is -2. Insert this value into either original equation:
[tex]2x+5(-2)=-16[/tex]
Solve for x. Simplify multiplication:
[tex]2x-10=-16[/tex]
Use inverse operations to get like terms on the same side of the equation. Add 10 to both sides (addition is the opposite of subtraction) to cancel out the -10 on the left:
[tex]2x-10+10=-16+10\\\\2x=-6[/tex]
Isolate the variable using inverse operations. The x term can be seen as 2×x. Division is the opposite of multiplication, so divide both sides by 2:
[tex]\frac{2x}{2}=\frac{-6}{2} \\\\x=-3[/tex]
The value of x is -3. Therefore, the solution to the system is:
[tex](-3_{x},-2_{y})[/tex]

Tilly and Lilly worked together on a job. Tilly earned twice as much as Lilly, and together they earned $510. How much did each person earn? Use the 5D Process, showing all your work.
Answer:
Lilly earns $170
Tilly earns $340
Step-by-step explanation:
Given that
Tilly earned twice as much as Lilly
If Lilly's earning = x, then Tilly's earning = 2x
Total amount they both earned = $510
x + 2x = $510
3x = $510
3x / 3 = $510 /3
x = $170
Hence,
Lilly earns x = $170
Tilly earns, 2x = 2* 170 = $340

Step-by-step explanation:
A number is called flippy if its digits alternate between two distinct digits. For example, 2020 and 37373 are flippy, but 3883 and 123123 are not. How many five-digit flippy numbers are divisible by 15?
A 3
B 4
C 5
D 6
E 8
Answer: B: 4
Step-by-step explanation:
A number is divisible by 15 if the number ends on a 0 or a 5, and the sum of its digits is divisible by 3.
We want to find a 5 digit flippy number, this can be: modeled with:
N = ababa
Where a and b are single digit numbers.
If we impose that N must end with a zero, then we will have:
N = 0b0b0 = b0b0
This is a 4-digit number, so we can discard all the options that end with a zero.
Then the only option that we have are the numbers like:
B = 5b5b5
This number will be only divisible by 15 if:
5 + b + 5 + b + 5 = K is divisible by 3.
Then let's try find the possible values of b.
K = 3*5 + 2*b
K has two terms, the left term is already divisible by 3, then K will be divisible by 3 only if the other term is also divisible by 3.
Then we want 2*b to be divisible by 3.
And 2 is a prime number, then b must be divisible by 3, and we know that b is a number between {0,1 , 2, 3, 4, 5, 6, 7, 8 ,9}
The options are:
2*0 = 0 is divisible by 3.
2*3 = 6 is divisible by 3.
2*6 = 12 is divisible by 3
2*9 = 12 is divisible by 3.
Then we have four values of b such that:
N = 5b5b5 is divisible by 15.
Then the correct option is: B: 4
Tell me a fun fact about horses will give BRAINLIEST to whoever tells me something I don’t know (I have been riding for 12 years) so I know a lot of things (also don’t tell me they can sleep standing up I already know that it’s kinda obvious)
Here are a few fun facts:
A 19th century horse named 'Old Billy' is said to have lived 62 years.
Horses can sleep both lying down and standing up.
Horses can run shortly after birth.
Horses have around 205 bones in their skeleton.
Horses have been domesticated for over 5000 years.
Horses use their ears, eyes and nostrils to express their mood.
Because horse’s eyes are on the side of their head they are capable of seeing nearly 360 degrees at one time.
The fastest recorded sprinting speed of a horse was 88 kph (55 mph). Most gallop at around 44 kph or 27 mph.
The Przewalski’s horse is the only truly wild horse species still in existence. The only wild population is in Mongolia. There are however numerous populations across the world of feral horses e.g. mustangs in North America.

Three pumpkins are catapulted at a contest. How much farther does Pumpkin C travel than Pumpkin A? • Pumpkin A travels 0.61 mile. • Pumpkin B travels 0.28 mile farther than Pumpkin A. • Pumpkin B travels 0.06 mile farther than Pumpkin C.
Answer:
0.22 miles
Step-by-step explanation:
Let
A = Distance pumpkin A travels = 0.61 miles
Distance pumpkin B travels is 0.28 mile farther than Pumpkin A
[tex]B=0.28+A\\\Rightarrow B=0.28+0.61\\\Rightarrow B=0.89\ \text{miles}[/tex]
Distance pumpkin B travels is 0.06 miles further than pumpkin C
[tex]B=0.06+C\\\Rightarrow C=B-0.06\\\Rightarrow C=0.89-0.06\\\Rightarrow C=0.83\ \text{miles}[/tex]
To calculate how much farther pumpkin C travels than pumpkin A we have the subtract their distances
[tex]C-A=0.83-0.61=0.22\ \text{miles}[/tex]
So, pumpkin C traveled 0.22 miles more than pumpkin A.

A water balloon is thrown upward from a height of 5 feet with an initial velocity of 35 feet per second. The quadratic function h(t)=-16t^2+35t+5 represents the height of the balloon, h, in feet t seconds after it is thrown. Determine when the balloon is more than 10 feet above the ground. Round your answer to the nearest thousandth.
Answer:
t>2.034s and t>0.154s
Step-by-step explanation:
Given the quadratic function h(t)=-16t^2+35t+5 which represents the height of the balloon, h, in feet t seconds after it is thrown.
To determine when the balloon is more than 10feet above the ground, we will substitute h = 10 into the expression to have;
h(t)=-16t^2+35t+5
-16t^2+35t+5>10
-16t^2+35t+5-10>0
16t^2-35t+5>0
Find t;
t > 35±√35²-4(16)(5)/2(16)
t>35±√1225-320/32
t>35±√905/32
t>35±30.08/32
t > 35+30.08/32 and t > 35-30.08/32
t>65.08/32 and t>4.92/32
t>2.034s and t>0.154s
Hence the balloon is more than 10feet above the ground at when t>2.034s and t>0.154s
