Answer:
y ≤ 5
Step-by-step explanation:
5 is the max value and the lowest is negative infinity so y is less than or equal to 5
Subtract the equations
3х+4y - 17
- (3x+2y = 3)
A. 6х + 20
ов. - 6x = 14
Ос, 2у= 14
Op. бу 20
Step-by-step explanation:
3x - 3x = 0,
4y - 2y = 2y, and
17 - 3 = 14.
Hence,
3x + 4y = 17
- (3x + 2y = 3)
=> 2y = 14.
The correct answer is Option c.

Write the equation you would use to solve for x. Then solve.
Answer:
x=12
Step-by-step explanation:
we know that the sum of the angles in a triangle is 180 degrees
to find x we have to calculate the sum of the angles
(10x-11)+(3x-2)+(3x+1)=180
10x-11+3x-2+3x+1=180
16x-12=180
16x=180+12
16x=192
x=192/16=12

= 3/7 : 1
This triangle has one side that lies on an extended line segment.
Based on this triangle, what statement about x is true?
x = 43 because 71−28=43 and 28 + 43 = 71
x = 81 because 180 − 71 − 28 = 81
x = 99 because 28 + 71 = 99 and 99 − 28 = 71
x = 137 because 180 − 71 + 28 = 109 + 28 = 137

The measure of angle x is; 137 degrees, the statement (4) x = 81 because 180 − 71 − 28 = 81 is true.
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
In a triangle, the measures of the three angles add up to 180 degrees. In this triangle, one of the angles measures 71 degrees, and another angle measures 28 degrees.
Therefore, the measure of the third angle must be 48 degrees.
Since the measure of the third angle is 48 degrees, and the measure of one of the other angles is 33 degrees, the measure of the remaining angle must be 48 - 33 = 15 degrees.
Then the measure of the third angle must be 180 − 71 - 28 = 81 degrees.
Therefore, the measure of angle x is 81 degrees.

Which of the following is the independent variable of G(F(y)) ?
A. F(x)
B. x
C.у
D. G(F(y))
SUBMIT
Given:
The composition of functions is G(F(y)).
To find:
The independent variable of G(F(y)).
Solution:
Independent variable is the variable whose value independent from other variable. It means the value of independent variables is not depend on the other variable.
We know that G(F(y)) can be written as
[tex]G(F(y))=(G\circ F)(y)[/tex]
Here, the value of function G depends on F(y) and the value of F(y) depend on variable y. But value of y does not depend on any variable. So, y is the independent variable of G(F(y)).
Therefore, the correct option is C.

if 2 of the angles of a triangle are 30 and 70 degrees, the third angle measures ...
Answer:
The third angle measures 80°
Step-by-step explanation:
Let us solve the question
In any triangle
∵ The sum of the measures of the interior angles of a triangle is 180°
∵ The angle of triangles are ∠1, ∠2, and ∠3
∴ m∠1 + m∠2 + m∠3 = 180°
∵ Two of the angles of the triangle are 30° and 70°
∴ m∠1 = 30°
∴ m∠2 = 70°
→ Substitute them in the rule above
∴ 30° + 70° + m∠3 = 180°
→ Add the like terms
∵ (30 + 70) + m∠3 = 180
∴ 100 + m∠3 = 180
→ Subtract 100 from both sides
∵ 100 - 100 + m∠3 = 180 - 100
∴ m∠3 = 80°
∴ The third angle measures 80°
A soup recipe calls for a common ratio of salt to pepper as ½ oz : ¼ oz. How much salt and pepper will be needed to create a seasoning mixture that has a total of 5 ¼ oz?
Answer:
Pepper = 1¾ Oz
Salt = 3½ Oz
Step-by-step explanation:
Given
Salt : Pepper = ½oz : ¼oz
Required
Determine the amount of salt and pepper needed for 5¼ Oz
For ease of calculation, we first convert the ratio to integers.
[Multiply ratio by 4]
Salt : Pepper = 4 * ½oz : 4 * ¼oz
Salt : Pepper = 2 Oz : 1 Oz
Total Ratio = 2 + 1 = 3
The amount of salt needed is then calculated as:
Salt = (Salt Ratio * 5¼)/(Total Ratio)
Salt = (2 * 5¼)/3
Salt = ⅔ * 5¼
Salt = ⅔ * 21/4
Salt = 42/12
Salt = 3½ Oz
Amount of Pepper is calculated as:
Pepper = (Pepper Ratio * 5¼)/(Total Ratio)
Pepper = (1 * 5¼)/3
Pepper = ⅓ * 5¼
Pepper = ⅓ * 21/4
Pepper = 21/12
Pepper = 1¾ Oz

the answer to the length of x is in mm. please help!
Answer:
3.69 mm
Step-by-step explanation:
So it's a right triangle so you can use a^2+b^2=c^2
Plugging in what we know the equation becomes:
2.8^2+2.4^2=c^2 (C = x because x is the hypotenuse)
7.84+5.76=c^2
13.6=c^2
The square root of 3.68782 which rounds to 3.69
So x=3.69mm
The sum of aanual interest and semi-annual compound interest on a sum of money for 2 years at the interest rate of 20% per annum is Rs. 18082. Find the differences.(Ans: Rs. 482)
The differences between the annual interest and semi-annual interest will be Rs 435.78.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
The same of annual interest and semi-annual compound interest on a same of money for 2 years at the interest rate of 20% per annum is Rs. 18082.
The annual interest will be
⇒ 18082(1.2)² – 18082
⇒ Rs 7956.08
The semi-annual interest will be
⇒ 18082(1.1)⁴ – 18082
⇒ Rs 8391.86
Then the differences between the annual interest and semi-annual interest will be
⇒ 8391.86 – 7956.08
⇒ Rs 435.78

The equation of line p is y= -7/8x + 3/2. line q is parallel to line p. what is the slope of line q?
Answer:
The slope of Line q is -7/8.
Step-by-step explanation:
Remember that for two lines to be parallel, their two slopes must be equivalent.
We are given that the equation of Line p is:
[tex]\displaystyle y=-\frac{7}{8}x+\frac{3}{2}[/tex]
So, the slope of Line p is -7/8.
Line p is parallel to Line q. Therefore, the two lines have the same slope.
Hence, the slope of Line q must also be -7/8.

If, so ANSWER THEM RIGHT!
Answer:
X Y
-2 8
-1 7
0 6
1 5
2 4
3 3
Step-by-step explanation:
We have the equation: x+y=6
We want to get this in the form: y=mx+b (or in this case y=x+b)
To do this we need y to be positive and by itself
So we subtract y from both sides and divide by -1 (we divide by -1 because otherwise y would be negative and that does not fit our template of y=x+b)
Doing this we have
-x+6=y
From here we just plug in numbers -2 to 3 which I will assume you know how to do
X Y
-2 8
-1 7
0 6

Step-by-step explanation:
let the total number of students in each bus be 'b',
Total number of students in 9 buses= 9b
Total number of students in cars= 9
Hence, Total number of students= 9b+9
= 414
Number of students in each bus = (414-9)/9
3x+4y=24
