Step-by-step explanation:
Given:
y = 6x - 11
-2x - 3y = -7
Required:
Find the solution.
Solution:
y = 6x - 11 ---› eqn. 1
-2x - 3y = -7 ----› eqn 2
Substitute y = (6x - 11) into equation 2.
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-20x + 33 = -7
Subtract 33 from each side
-20x = -7 - 33
-20x = -40
Divide both sides by -20
x = -40/-20
x = 2
Substitute x = 2 into equation 1.
y = 6x - 11 ---› eqn. 1
y = 6(2) - 11
y = 12 - 11
y = 1
The solution is very (2, 1)

Answers
Answer:
x = 12
Step-by-step explanation:
We know that the integers are consecutive. This means that they can be written as:
x, x + 1, and x+2.
First Integer: x
Second Integer: x + 1
Third Integer: x + 2
It is also given that the sum of the first integer and twice the second is 80 minus three times the third.
Write as an equation:
First Integer + 2(Second Integer) = 80 - 3(Third Integer)
Substitute:
x + 2(x+1) = 80 - 3(x+2)
Multiply:
x + 2x + 2 = 80 - 3x - 6
Simplify:
3x + 2 = 74 - 3x
Add 3x to both sides of the equation:
6x + 2 = 74
Subtract 2 from both sides of the equation:
6x = 72
Divide both sides of the equation by 6:
x = 12

Answer:
Smallest Integer = 12Step-by-step explanation:
According to question ,
• First Integer → x
• Second Integer → x + 1
• Third Integer → x + 2
Now question says that the sum of the first and twice the second is 80 minus three times the third that means ,
→ x + 2 ( x + 1 ) = 80 - 3 ( x + 2 )
→ x + 2x + 2 = 80 - 3x - 6
→ 3x + 2 = -3x + 74
→ 3x + 3x = 74 - 2
→ 6x = 72
→ x = 72/6
→ x = 12
Hence , value of x is 12 that means :
→ x = First Integer = 12
→ x + 1 = Second Integer = 13
→ x + 2 = Third Integer = 14
In all of these x is the smallest integer and hence 12 is the correct answer .

In a class of 30 students, 12 have a brother and 25 have a sister. There are 2 students who do not have any siblings. What is the probability that a student who has a brother also has a sister?
Answers
Answer:
3/10
Step-by-step explanation:
let n(B)=students who have a brother
n(S)= students who have a sister
n(U)=n(B)+n(S)+n(BUS)'-n(BnS)
30=12+25+2-n(BnS)
30=39-n(BnS)
n(BnS)=39-30=9
So 9 students have a brother and a sister
Probability=9/30=3/10
The probability that a student who has a brother also has a sister will be 0.30.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
In a class of 30 students, 12 have a brother and 25 have a sister. There are 2 students who do not have any siblings.
The number of students who have both brothers and sisters. Then we have
25 - x + 12 - x + x + 2 = 30
x = 25 + 12 + 2 - 30
x = 9
Then the probability that a student who has a brother also has a sister will be given as,
P = 9 / 30
P = 0.30
The probability that a student who has a brother also has a sister will be 0.30.

Answers
Answer:
Each point will plot to only one place in the coordinate plane. So, I don't know what you mean by plotting anywhere and you'll get the same result. You won't
Step-by-step explanation:
Answer:
The signs of a point's coordinates affect where the point is on a coordinate plane because an X-coordinate being negative or positive tells how far to the right or left of the Y-axis a point is. Vice versa, the Y-coordinate being positive or negative says how far above or below the X-axis a point is on a coordinate plane.

A person invests $1000 in a bank. The bank pays 6% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches $3300
Answers
Answer:
18 years, 4 months and 10 days.
Step-by-step explanation:
Given that the person invests $ 1000 in an account with compound interest each month, with an interest rate of 6%, to determine how long the investment must maintain to reach $ 3,000, the following calculation must be performed:
3,000 = 1,000 (1 + 0.06 / 12) ^ Yx12
3,000 = 1,000 (1 + 0.06 / 12) ^ 18.36x12
3,000 = 3,000
Therefore, the person must keep his investment for a period of 18.36 years. Since 12 x 0.36 is equal to 4.32, the total investment time should be 18 years, 4 months and 10 days.

Step-by-step explanation: Am not sure if this is the answer you guys are looking for but my in 9th grade and this is how my math teacher taught me how to do it.one chocolate cake=?=x
one lemon cake=?=y
$270 spent
need to buy total of 18 cakes
1-chocolate cake =$7
lemon cake = $5
cakes 18=x+y
money $110=$7x+$5y
When i graphed it on the demos calculator i got (10,8).
So 10= the number of chocolate cake brought and 8= the number of lemon cake brought
The number of lemon cakes Jasmine can buy for the party is 8.
System of linear equationsTwo equations can be deduced from the question:
a + b = 18 equation 1
$7a + $5b = $110 equation 2
Where:
a = number of chocolate cakes boughtb = number of lemon cakes boughtDetermining the number of lemon cakes that can be bought
In order to determine the number of lemon cakes that can be bought, take the following steps:

Find the GCF of the pair of monomials.
32a,48a
Answers
Answer:
The greatest common factor (GCF) of these two monomials is [tex]16\, a[/tex].
Step-by-step explanation:
Rewrite [tex]32\, a[/tex] and [tex]48\, a[/tex] as the products of the variable [tex]a[/tex] and and prime number factors:
[tex]32\, a = 2 \times 2 \times 2 \times 2 \times 2 \times a = 2^{5}\times a[/tex] (where [tex]2[/tex] is a prime factor.)[tex]48\, a = 2 \times 2\times 2 \times 2 \times 3\times a = 2^{4}\times 3\times a[/tex] (where [tex]2[/tex] and [tex]3[/tex] are both prime factors.)Write an expression for the GCF of these two monomials in terms of these factors ([tex]2[/tex]'s, [tex]3[/tex], and [tex]a[/tex].) Try to include as many of each factor as possible, as long as the resulting product is present in both monomials.
For example, there are five factor [tex]2[/tex]'s in the first monomial but only four in the second monomial. Therefore, include the factor [tex]2\![/tex] in the GCF for only four times.
The factor [tex]a[/tex] appeared once in both monomials. Hence, include [tex]a\![/tex] for one in the expression for the GCF.
On the other hand, the factor [tex]3[/tex] is found in the second monomial but not in the first. Therefore, this factor should not be included in the expression for the GCF.
Therefore, the expression for the GCF would be:
[tex]2 \times 2\times 2\times 2 \times a = 16\, a[/tex].
What's the slope and y-intercept of the equation y = 9? Question 3 options: A) m = 0; b = -9 B) m = 0; b = 0 C) m = 0; b = 9 D) m = 9; b = 0
Answers
Answer:
b
tep-by-step explanation:
The correct option is C) m = 0; b = 9. The slope and y-intercept of the linear equation y = 9 are m = 0; b = 9.
To explain step by step:
The equation y = 9 represents a horizontal line that intersects the y-axis at the point (0, 9).The slope of a horizontal line is always zero because there is no change in the y-coordinate as x varies.Therefore, the slope (m) of the equation y = 9 is 0.The y-intercept (b) is the value of y when x is zero. In this case, when x is zero, y remains constant at 9.Thus, the y-intercept (b) of the equation y = 9 is 9.In summary, the slope of the linear equation y = 9 is 0, indicating a horizontal line, and the y-intercept is 9, representing the point where the line intersects the y-axis.
