-5x+7y=-34
-5x+3y=-6
Answers
Answer:
x = -3, y = -7Step-by-step explanation:
-5x + 7y = -34 ⇒ -5x = -34 - 7y
-5x + 3y = -6
-34 - 7y + 3y = -6
-34 - 4y = -6 {add 34 to both sides}
-4y = 28 {divide both sides by (-4)}
y = - 7
-5x + 3y = -6
-5x + 3(-7) = -6
-5x - 21 = -6 {add 21 to both sides}
-5x = 15 {divide both sides by (-5)}
x = -3

Step-by-step explanation: You can order without knowing the areas because of the size
Answer:
From Left to Right:
Large, Medium, Small
Explanation:
Assuming all the numbers are the same (chances are that they are seeing as they use the same variable ((the Greek lowercase letter known as Psi - Ψ)), then we should determine the area based on formulas.For the leftmost shape, you have to use the length * width formula TWICE and then subtract the missing area value to find the remaining area (which is--even after subtracting, the greatest than out of all the other shapes).For the middle shape, the formula you use is length * width-- which is less than that of the leftmost shape, but more than the rightmost shape.For the rightmost shape, the formula you use is (length * width)/2--which is half of the middle shape and less than the largest shape.38.

One of the angles of a triangle is 8 deg more than 5 times another angle. If the third angle is 4 deg larger than the difference of the first two angles, find the angles.
Answers
Answer:
[tex]16^\circ, 88^\circ, 76^\circ[/tex]
Step-by-step explanation:
Given a triangle.
One of the angles is [tex]8^\circ[/tex] more than 5 times of one angle.
Third angle is [tex]4^\circ[/tex] more than the difference of two angles.
To find:
The angles.
Solution:
Let the first angle = [tex]x^\circ[/tex]
As per question statement, second angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex]
And third angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex] - [tex]x^\circ[/tex] + [tex]4^\circ[/tex] = [tex](4x+12)^\circ[/tex]
Using triangle sum property that the sum of all the internal angles of a triangle is always equal to [tex]180^\circ[/tex].
[tex]x+5x+8+4x+12 = 180\\\Rightarrow 10x+20=180\\\Rightarrow 10x = 160\\\Rightarrow x = 16[/tex]
Therefore, the first angle = [tex]x^\circ = 16^\circ[/tex]
The second angle = [tex]5x+8 = 5 \times 16 + 8 = 80+8 = 88^\circ[/tex]
The third angle = [tex]4x+12 = 4\times 16 + 12 = 76^\circ[/tex]
Therefore, the angles are [tex]16^\circ, 88^\circ, 76^\circ[/tex].

Answers

Answer:
see the attachment
Step-by-step explanation:
There are no roots, fractional powers, or denominators containing variables, so each of these expressions is the sum of multiples of products of variables to integer powers. (One is a constant.) That makes each expression a polynomial. Some polynomials can be further classified by their degree.
The degree is the highest sum of powers of the variables in the terms. For example, the term a^2·b·c^2 has variables with powers 2, 1, and 2. The sum of those powers is 2+1+2 = 5, so this is a term of degree 5.
A constant is a term with no variables.
__
It is customary in algebra problems to use variables that are a single lower-case letter. Sometimes, a variable may be represented by a letter in uppercase, or in a special font or language (usually Greek). Sometimes, it may be a word or phrase. Here, we assume each variable is one letter, so xyz is the product of three variables.
Perhaps the table below answers the questions you are asking about these expressions.

Correct question
A sequence is defined by the term-to-term rule
Un+1 = u. + 3
Given that u1 = 1,
a) find u2
b) find u3
c) find u5
a) Given the recursive formula;
Un+1 = un + 3
When n = 1;
U1+1 = U1 + 3
U2 = U1 + 3
U2 = 1 + 3
U2 = 4
b) U3 = U2 + 3
U3 = 4 + 3
U3 =7
c) U4 = U3 + 3
U4 = 7+3
U4 = 10
U5 = U4 + 3
U5 = 10 + 3
U5 = 13

What is the largest 2-digit composite number divisible by 46?
Answers
Answer:
92
Step-by-step explanation:
its 92 because its is a 2-digit number and is considered composite because its divisible by 2, 4, 23 and 46
The largest 2-digit composite number divisible by 46 is 92 and this can be determined by using the definition of composite numbers and by arithmetic operations.
Given :
Number - 46
The following steps can be used to determine the largest 2-digit composite number divisible by 46:
Step 1 - Remember that composite numbers are those numbers that are divisible by more than two numbers.
Step 2 - The two-digit composite numbers which are divisible by 46 are 46 and 92.
Step 3 - The largest number between 46 and 92 is 92.
So, the largest 2-digit composite number divisible by 46 is 92.

9. The diagram shows a triangle inscribed in a circle with centre O.
The lengths of the shorter sides of the triangle are 6 cm and 8 cm.
Work out the area of the circle.
Use π = 3.14.
Answers
Answer:
25π
Step-by-step explanation:
let c = length of third side of triangle
since you are working with a right triangle you can find the third side by using the pythagorean theorem: 8^2 + 6^2 = c^2
64 + 36 = c^2
100 = c^2
c = 10
10 is also the diameter of the circle and radius is 5
