How to get the answer for y=2x+3,4x-3y=1 substitution method
Answer:
x=−5 and y=−7
Step-by-step explanation:
Step: Solve y=2x+3for y:
y=2x+3
Step: Substitute2x+3foryin4x−3y=1:
4x−3y=1
4x−3(2x+3)=1
−2x−9=1(Simplify both sides of the equation)
−2x−9+9=1+9(Add 9 to both sides)
−2x=10
−2x
−2
=
10
−2
(Divide both sides by -2)
x=−5
Step: Substitute−5forxiny=2x+3:
y=2x+3
y=(2)(−5)+3
y=−7(Simplify both sides of the equation)

1.D)SSS
2.C.)
Step-by-step explanation:
1. There isn't any angles and there is enough info to prove that the triangles are congruent.
2.There is not enough info to determine that the triangles are congruent.
perfect square trinomial conditions
Step-by-step explanation:
step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.
step 2. dos must have only 2 square rootable terms and a "-" between them.
step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!
step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!
step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!
step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!
Is y=x^2+7 a linear equation?
Answer:
No, it is not a linear equation
Step-by-step explanation:
This equation contains the term x², meaning that it is a quadratic function (parabola)
So, it is not a linear equation.
If it were a linear equation, x would not be squared, and the equation would have been in y = mx + b form.
The answer is no, it is not a linear equation.
Answer:
Given :-[tex] \large \sf \bullet \: y = {x}^{2} + 7[/tex]
To Find :-Is it a linear Equation
Solution :-We may notice that
x has power as 2.
So,
We know that
A linear Equation doesn't consist of power. Linear equation only consist of variable and constant.
No,

How would I go about solving this problem? I used the Pythagorean theorem but still got it wrong
Answer:
B. 20
Step-by-step explanation:
Using the Pythagorean Theorem, you have:
[tex]a^2 + b^2 = c^2\\24^2 + 32^2 = c^2\\576 + 1024 = c^2\\1600 = c^2\\c = 40[/tex]
So you know side AB is 40 inches long. It asks the length of the midpoint to point A, so you have to do 40/2 = 20 inches
Last homework for mathematics, mr Thompson!
Answers:
Have a common difference Have a common factor Have a linear first difference============================================================
Explanation:
Linear functions, such as y = 2x+5, have a common difference. In that example, the common difference would be 2 since we add 2 to each term to get the next one. Consider when x = 1 and that leads to y = 7. Then when x = 2, we have y = 9. Then when x = 3, we have y = 11, and so on. The sequence of y values {7,9,11,...} shows we add 2 each time.
------------------
Exponential functions have us multiply the previous term by some common factor to get the next term. A sequence like {2,6,18,...} has us multiply by 3 each time and the exponential function modeling this sequence is y = 2(3)^(x-1) where x is a natural number. So this is an example showing that exponential functions have a common factor, or we can call this a common ratio.
------------------
Quadratic functions are a bit strange.
Let's consider the quadratic of y = x^2. The sequence of y values it generates is {1,4,9,16,25...} for positive integers x = 1, 2, 3, 4, 5....
Let's subtract the adjacent terms (larger - smaller)
4-1 = 39-4 = 516-9 = 725-16 = 9Note the results of 3,5,7,9 are in a linear sequence (we're adding 2 to each increment value, so the next increment would be +11). We can consider this a linear first difference.
------------------
For any of these functions, I'm restricting x to be an integer and x = 1 is the smallest input possible.
El jueves se vendieron 13.520 entradas para ver un partido de hockey y el viernes 14.608. Si en el polideportivo caben 50.000 personas. ¿Cuántas entradas se pueden vender todavía?
Answer:
21,872 tickets
Step-by-step explanation:
The computation of the number of tickets to be still sold is given below:
= Total people accommodated - total number of tickets sold yet
= 50,000 people - (13,520 tickets + 14,608 tickets)
= 50,000 people - 28,128 tickets
= 21,872 tickets

Joe needs to buy snacks for the chess club. There are 12 people in the club and he wants each person to receive 0.5 pounds (lbs) of grapes. How many pounds of grapes should he buy?
Answer: 6 pounds of grapes
Step-by-step explanation:
There are 12 people that Joe is meant to buy for.
Each of them will receive 0.5 pounds of grapes.
All of them will therefore need:
= pounds of grapes per person * number of people
= 0.5 * 12
= 6 pounds of grapes

On the number line bug A is moving in the positive direction from the point 0, and a bug B is moving in the negative direction from the point 0. The speeds of both bugs are constant. Both leave 0 at the same time, and three seconds later A has reached 18 and B has reached -15
If x is the point reached by A after t seconds, and y is the point reached by B after t seconds, express x and y in terms of t.
Answer:
x =6t
y = - 5t

On the number line, which point is the closest pi .
A.
B.
C.
D.
The closest point to the number line is C.
Hence Option C is correct.
In the given number line
There are 10 equidistant points between 3.1 and 3.2
So, the set of points shown on the line is,
{3.1, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.2}
Therefore,
Point c represents point 3.14 approximately.
Since we know that π is an irrational number,
So it is non-terminating and non-repeating but for approximation,
π = 22/7
π ≈ 3.142
Hence,
The point C is very close to the π.
