Answer:
A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.
A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.
There are many different methods in arriving to the final answer. However, errors cannot be perfectly avoided. One of these errors to mistakenly identify equations as linear. It is important that we know that the equations we are dealing with are of exact or correct characteristics.
Also, if she had used substitution method, she might have mistakenly taken the value of one variable for the other.

what is the slope or yhe line yoing through (-2,-1) (1,2)
Answer:
Slope: 1
Step-by-step explanation:
You can find the slope by doing change in y/change in x.
Change in y is 3
Change in x is 3
So 3/3 is 1, and the slope is 1

Find the midpoint of a segment with endpoints (-9, 3) and (5, 7).
I need help ASAP pleasee
Answer:
( -2,5)
Step-by-step explanation:
To find the x coordinates of the midpoint, add the x coordinates of the endpoint and divide by 2
( -9+5)/2 = -4/2 = -2
To find the y coordinates of the midpoint, add the y coordinates of the endpoint and divide by 2
( 3+7)/2 = 10/2 = 5
The midpoint is ( -2,5)
O preço a ser pago por uma corrida de táxi inclui uma parcela fixa, denominada bandeirada, e uma parcela que depende da distância percorrida. Se a bandeirada custa R$ 3,44 e cada quilômetro rodado custa R$ 0,90, determine a distância máxima que se pode percorrer com R$20,00
Answer:
18 quilômetros
Step-by-step explanation:
Aqui, queremos determinar a distância máxima que pode ser percorrida com R $ 20
A partir da pergunta, entendemos que cada viagem tem um valor fixo de R $ 3,44 e um valor variável de R $ 0,90 com base na quantidade de quilômetros.
Seja x o número de quilômetros percorridos em R $ 20 Portanto, temos a equação como; 3,44 + 0,9 (x) = 20
0,9x = 20-3,44
0,9x = 16,56
x = 16,56 / 0,9
x = 18,4
Arredondando para o quilômetro mais próximo, a distância máxima que pode ser percorrida com R $ 20 é de 18 quilômetros
The spinner below has three regions: $5, $0, and $10. To play the game, you spin one time and then you win the amount in the region that the spinner lands on. a.) What is the expected value for the game? b) If you have to pay $10 to play, is it a fair game? *
a) $5.00 b) no
a) $4.79 b) yes
a) - $ 8.75 b) no
a) $ 3.00 b) yes
Answer:
$5.00 ; no
Step-by-step explanation:
Given that:
135 / 360 = 0.375
90 / 360 = 0.25
135/ 360 = 0.375
X ___ 5 _____10 _____ 0
P(x): _0.25___0.375___0.375
Expected value :
ΣX*p(X) :
5(0.25) + 10(0.375) + 0(0.375)
1.25 + 3.75 + 0
= $5
b) If you have to pay $10 to play, is it a fair game?
For the game to be fair :
Amount paid = Expected winning
$10 ≠ $5
Since, amount paid is greater than expected winning, then the game is not fair
evaluate
f(12)=3/2x+14
f(-4)=3/2x+14
f(0)=3/2x+14
When f(x) is substituted with a number, you just plug the number into wherever you see x:
_____________
f(12) = 3/2x + 14
f(12) = 3/2(12) + 14
f(12) = 18 + 14
f(12) = 32
f(-4) = 3/2x + 14
f(-4) = 3/2(-4) + 14
f(-4) = -6 + 14
f(-4) = 8
f(0) = 3/2(0) + 14
f(0) = 0 + 14
f(0) = 14
What is m∠TVU?
m∠TVU = __°
[tex]4x + 3 = 3x + 12[/tex]
Both sides minus 3
[tex]4x = 3x + 12 - 3[/tex]
[tex]4x = 3x + 9[/tex]
Both sides minus 3x
[tex]4x - 3x = 9[/tex]
[tex]x = 9[/tex]
So :
TVU = 3(9)+12 ----¢ TVU = 27 + 12
TVU = 39°

Please answer will give brainliest! What is the distance between −93 and 114 on a number line? −207 −21 21 207
−207
−21
21
207
Answer:
207
Step-by-step explanation:
It automatically can not be -207 and -21 because you can't have a negative distance. To find the correct answer between 21 and 207, first you have to add 93 and 114. You do this because -93 is below the number line, so you have to add it to 114. 114 + 93 = 207
207

which expression is equivalent to 1/4 n - 16
a 1/4 (n-4)
b 1/4 (n-64)
c 4(n-4)
d 4(n-64)
9514 1404 393
Answer:
b 1/4 (n-64)
Step-by-step explanation:
Multiplying the expression by 1 does not change its value:
= (1/4)(4) × (1/4n -16)
= (1/4) × (4(1/4n -16)) . . . . . associative property
= (1/4) × ((4/4)n -4·16) . . . . distributive property
= (1/4)(n -64) . . . . matches choice B

is 2yx – 3y + 2x = 0 a linear function or not a linear function
is a linear function because It forms a straight line or represents the equation for the straight line
It has only one degree. Or we can also define it as an equation having the maximum degree 1.
All these equations form a straight line in XY plane. These lines can be extended to any direction but in a straight form.
The general representation of linear equation is;
y = mx +c
Where x and y are the variables, m is the slope of the line and c is a constant value.
Is 4 a solution to the compound inequality x>0 and x<7
Answer:

- 2x + 3y = 14
x + 2y = 7
Answer:
x = -1 , y = 4Step-by-step explanation:
x + 2y = 7 ⇒ x = 7 - 2y
- 2x + 3y = 14
- 2(7 - 2y) + 3y = 14
-14 + 4y + 3y = 14
-14 +7y +14 = 14 +14
7y = 28
y = 4
x = 7 - 2y = 7-2(4) = 7 - 8 = -1

A family car is being tested for fuel efficiency. It drives non-stop for 100 miles and uses 3.2 gallons of gasoline. Which of the following is the rates of distance traveled to fuel used?
Answer:
31.25miles per gallon
Step-by-step explanation:
Distance traveled = 100miles
Quantity of gasoline used = 3.2gallons
Unknown:
Rates of distance traveled to fuel used = ?
Solution:
The rates of distance traveled to fuel used is given as;
Rates = [tex]\frac{distance traveled}{fuel used }[/tex]

1. Ed Shapiro works as an office manager. His annual salary is $48,300. What is his monthly salary?
Answer:
The answer is $4025
Step-by-step explanation:
In this problem we are given his annual salary. meaning per year. to find how much he makes in a month, we must divide by how many months there are in a year.
there are 12 months in a year.
so, 48300/12= 4025
hope this helps!
Answer:
$4,025 is his monthly salary.
Step-by-step explanation:
Annual salary means yearly. Since there are 12 months in a year, you would just take his annual (yearly) salary and divide it by 12 in order to get his monthly salary. Thus it would be:
[tex]\frac{48300}{12} =4025[/tex]
