Answer:
x = 2, y = 5
Step-by-step explanation:
Given the 2 equations
y = - 2x + 9 → (1)
y = 4x - 3 → (2)
Substitute y = 4x - 3 into (1)
4x - 3 = - 2x + 9 ( add 2x to both sides )
6x - 3 = 9 ( add 3 to both sides )
6x = 12 ( divide both sides by 6 )x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4(2) - 3 = 8 - 3 = 5
Then x = 2, y = 5

In a right triangle, apart from the right angle, the other two angles are
x + 1 and 2x + 5. find the angles of the triangle.
Answers
Answer:
The two other angles are 29 degrees and 61 degrees
Step-by-step explanation:
There are 180 degrees in a triangle. Given this is a right triangle one of the angles is 90 degrees. As in the other two angles have to equal up to 90 degrees. Now we have to find x.
180 - 90 = 90
If x equals 28
28 + 1 = 29
2 x 28 + 5 = 61
29 + 61 = 90
The two other angles are 29 degrees and 61 degrees
Answer:
29 , 61
Step-by-step explanation:
Sum of all angles of a triangle = 180
90 + x + 1 +2x +5 = 180 {Combine like terms}
96 + 3x = 180 {Subtract 96 from both sides}
3x = 180 - 96
3x = 84 {Divide both sides by 3}
x = 84/3
x = 28
x +1 = 28 +1 = 29
2x +5 = 2*28 + 5 = 56 + 5 = 61

Step-by-step explanation:
Бардык белгилүү авиация мыйзамдарына ылайык, аары учуу мүмкүнчүлүгү жок.
Step by step: This is exponential growth. f(x)=a(1+r)^x where a is the original amount, r is the rate, and t is the time (in this case, number of years).
2.8% is equivalent to 0.028.
Because this is exponential growth, you add 1 to 0.028.
b(x)=33,741(1.028)^x

One side of the triangle is 4 cm, and the sum of the other two sides is equal to a
whole number of cm. What is the smallest possible perimeter of the triangle?
A. 9 cm
B. 10 cm
C. 11 cm
D. 15 cm
E. 17 cm
Answers
Answer:
A) 9 cm
Step-by-step explanation:
By the Triangle Inequality, any two sides of a triangle must be greater than the remaining side.
In order to minimize the perimeter, we will assume that 4 cm is the longest side.
Thus, the two remaining sides must be greater than 4.
Since we are given that the sum of the two remaining sides is a whole number, the smallest whole number value greater than 4 is 5.
Hence, the smallest perimeter possible 9 cm.
Our answer is A.

Hello! answer: 17
Step-by-step explanation:
Assuming this is the Pythagorean theorem our formula would be
a^2 + b^2 = c^2
meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...
15 × 15 = 225 8 × 8 = 64 225 + 64 = 289
the square root or the (number multiplied byitself that equals 289) is 17 because
17 × 17 = 289 so × = 17 I hope that helps!
Answer:
x = 17 cm
Step-by-step explanation:
Since it is a right triangle and you are trying to find x, you can use the pythagorean theorem. (a² + b² = c²)
First, plug the values into the equation: (a and b represent the legs and c represents the hypothenuse; otherwise known as the longest side.)
8² + 15² = c²
Square 8 and 15( or multiply them by themselves):
64 + 225 = c²
Add:
289 = c²
Take the square root of both sides:
√289 = √c²
Simplify:
17 = c
Therefore, x = 17 cm.
Hope this was helpful! Have a nice day! :)

If a student likes hotdogs, what is the probability that student also likes burgers?
93.8%
50.7%
42.1%
39.5%
Answers
Answer:
like burgers with the wrong total of 76/150 is 50.7%
do not like burgers with also the wrong total of 74/150 is 50% simplified
now with the right totals its 54% for liking burgers and 46% for not liking
Step-by-step explanation: 32 + 49 + 81 = 162
44 + 25 + 69 = 138
right total (162) wrong total (76)
right total (138) wrong total (74)
right (300) wrong (150)
unless u simplified by 2 which is 150/300 then its right simplified
so im confused but this is my answer
Answer:
Years late but I'll answer anyway. It is C. 42.1%
Step-by-step explanation:
A two-way table is a bivariate table. Bivariate tables have rows and columns just as your table has.
Remember, a column is vertical and a row is horizontal. Each value in the data table is called a cell.
In this case, you have to do column relative frequency. This is a cell frequency divided by the column total. It's not as hard as it may sound.
The number of people who like hotdogs and burgers is 32, and the total for that column is 76. All you have to do is divide 32 by 76 and you have your answer.
32 / 76 = 0.421 or 42.1%
A ball rolled from Point A to Point B in 18 second at a speed of 14 m/s. IT took another 18 seconds to roll form Pint B to Pint C at a speed of m/s. Find the total distance the ball rolled.
Answers
Answer:
d=252m, u dint put the speed it was rolling at from point B to C so I could only solve for A to B. However if you use the formula below you can find the distance from B to C and add that to A to B giving the total distance rolled.
Step-by-step explanation:
d=vt
v=14m/s
t=18s
d= vt, (14m/s)(18s)
d=252m

Answers
Answer:
Look at the image.
Step-by-step explanation:
The required model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B. Option B is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is an array?The array is a collection of things and shapes in a specific pattern.
Here,
Given that, to determine the model that represents 9 (3+6) = (9 x 3) + (9 x 6)
So 9 (3+6) = (9 x 3) + (9 x 6) represents the arrangement of squares in array form,
If in a pattern there are 9 rows there must be 3 and 6 columns or vice versa.,
So from the above definition, a model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B.
