Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y + 5x = 1
5y - x = 5
Step 2: Rewrite Systems
y + 5x = 1
Subtract 5x on both sides: y = 1 - 5xStep 3: Redefine Systems
y = 1 - 5x
5y - x = 5
Step 4: Solve for x
Substitution
Substitution in y: 5(1 - 5x) - x = 5Distribute 5: 5 - 25x - x = 5Combine like terms: 5 - 26x = 5Isolate x term: -26x = 0Isolate x: x = 0Step 5: Solve for y
Define equation: 5y - x = 5Substitute in x: 5y - 0 = 5Subtract: 5y = 5Isolate y: y = 1SOMEONE PLEASE HELP ME WITH THIS I NEED IT!!!

PLEASE I NEED HELP!! what are two ways that you can tell that two ratios form a proportion? i really need to pass this test to get my grades up, I'm not trying to cry my whole winter break.
Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."
Step-by-step explanation:
Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fraction in it’s simplest form. Another way is to see if the numbers in the ratios are factors or multiples of each other. For example, 10:5 and 30:15. 10:15= 10/5 and 30:15= 30/15. Then you put it in simple form. 10/5 = 2 and
30/15 = 2. Therefore 10:5 and 30:15 are proportional.

Dillon pays x dollars to get a haircut. He gives the stylist a
25% tip. The expression representing his total cost is
x + 0.25x
Which expression is equivalent and why?
A. 1.025x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.025.
B. 1.25x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.25.
C. 1.25x because adding $25 to the haircut is the same as
multiplying the cost by 1.25.
D. x(0.25) because the cost of the haircut can be factored out.
Answer:
B
Step-by-step explanation:
the percentage of money to be paid is 125% which is equivalent to 1.25 in fraction
The equivalent expression is" 1.25x because adding 25% to the cost of the haircut is the same as multiplying the cost by 1.25. Option B is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that, Dillon pays x dollars to get a haircut. He gives the stylist a 25% tip. The expression representing his total cost is,x + 0.25x
Expressions that function identically while having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then they both have the same result when the same value of the variable is entered.
=x + 0.25x
=1.25x
Thus, the equivalent expression is" 1.25x because adding 25% to the cost of the haircut is the same as multiplying the cost by 1.25. Option B is correct.

solving systems equations: substitution
y=6x+5
y=4x+5
Answer:
y=6x+5 →equation 1
y=4x+5 → equation 2
you can either substitute equation 1 in 2 or equation 2 in 1
substituting equation 1 in 2,
y = 4x + 5
6x + 5 = 4x + 5
6x - 4x = 5 - 5
2x = 0
x = 0/2
x = 0
substituting x = 0 in equation 1, (to get y)
y = 6x + 5
y = 6(0) + 5
y = 0 + 5
y = 5

The points (-2, 4) and (1,r) lie on a line with slope 3. Find the missing coordinate r.
Answer:
-9
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
(r - 11)/(4 - (-1)) = (r - 11)/5
So, (r - 11)/5 = -4
r - 11 = -20
r = -9

Here are graphs of two functions f and g the function h is defined by h(x)=f(x)-g(x)
1.for which values of x is h(x)=0? explain how you know
2.For which values of x is h(x) 0
3.sketch a graph of h
I am not good at math and don't feel like taking it again pleas help ;-;
i did this last year lol ;-;
The function h(x) is h(x)=5/4 x² - 5/2 x.
What is quadratic equation of graph?A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola.
The vertex form of a quadratic function is f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. The coefficient a determines whether the graph of a quadratic function will open upwards or downwards.
Here, vertex is (h, k)=(0, 0) and coordinate point is (x, y)=(-2, 5)
So, 5=a(-2-0)²+0
5=4a
a=5/4
Substitute, a=5/4 and (h, k)=(0, 0) in vertex form we get
f(x)= 5/4 x²
Equation of straight line with coordinates (-2, 5) and (0, 0) is
Slope m=5/2
Substitute, m=5/2 and (x, y)=(0, 0) in y=mx+c we get
0=5/2(0)+c
c=0
Substitute, m=5/2 and c=0 in y=mx+c we get
y=5/2 x
So, g(x)=5/2 x
Now, h(x)=f(x)-g(x)
h(x)=5/4 x² - 5/2 x
h(x)=5/2 x(1/2 x-1)
1) h(x)=0
5/2 x(1/2 x-1) =0
1/2 x-1=0
1/2 x=1
x=2
2) For x=2, h(x) is 0
3) Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Therefore, the function h(x) is h(x)=5/4 x² - 5/2 x.

Question: Reflective symmetry over y = (3/5)x ?
Answer: No
-------
Question: Reflective symmetry over y = (5/3)x ?
Answer: No
================================================
Explanation:
For any parallelogram that's a square, we'll have four lines of symmetry: The two diagonals and two extra lines of symmetry for the opposite pairs of sides.
In this case, we don't have a square (we can prove this by finding the lengths of each side of the parallelogram), so we move on.
--------------
If the parallelogram is a rectangle, then we'll have two lines of symmetry: one for each pair of opposite sides.
However, we don't have a rectangle either. We can prove this by finding the slopes of the blue lines of the parallelogram, and finding they are not perpendicular slopes.
So we move on.
---------------
The last case is a parallelogram that isn't a rectangle. So it's not a square either. That's what we have here. For parallelograms of this nature, there are no lines of symmetry. We cannot fold it along any line to have it match up with itself.
So that's why the answer is "no" to both of these questions.

No and No.

blake is saving up on a new pair of headphones. He has $20 saved already, and he earns $10 for every lawn he mows. How many lawns will he have to mow to have at least $90 saved . What is the inequality and the solution?
Answer: 20× + 10 < 90
Step-by-step explanation:
Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7
What is inequality?Inequality is a mathematical statement that compares two values, expressing that one value is less than, greater than, less than or equal to, greater than or equal to, or not equal to another value.
Inequalities are commonly represented using symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).
Let's assume Blake has to mow x lawns to have at least $90 saved.
Since he earns $10 for every lawn he mows, the amount he will earn by mowing x lawns is 10x.
Adding his initial savings of $20 to the amount he will earn from mowing lawns gives us the following inequality:
20 + 10x ≥ 90
Subtracting 20 from both sides:
10x ≥ 70
Dividing both sides by 10:
x ≥ 7
Therefore, Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7
