i don’t understand this
Answer:
it means that
y–x+6.8= 7.2–(–2)+6.8
–(–) will change into +
=7.2+2+6.8
=7.2+2.0+6.8

1/x
10/x
1-x
10-x
Answer:
I think it's 10-x because that would give you a negative number
need geometry help asap please
Answer:
x = 20
Step-by-step explanation:
You're in luck I take H geometry.
What I'm going to do is this. 4x - 18 and 3x + 2 are alternate interior angles so they equal the same, so use this equation.
4x -18 = 3x + 2 (add 18 on both sides)
4x = 3x + 20 (minus 3x on both sides)
x = 20
plug in
4(20) - 18 = 3(20) + 2
80 - 18 = 60 + 2
62 = 62

Step-by-step explanation:
100% on edge
Have a nice day :]
The equation in vertex form is [tex]y = (x + 3)^2 + 1[/tex], and the values of h & k are -3 and 1
What is the vertex form?The vertex form of an equation is a quadratic equation, written in the form of a parabola
The equation is given as:
[tex]y = x^2 + 6x + 10[/tex]
Write out the constant
[tex]y = (x^2 + 6x) + 10[/tex]
Take the coefficient of x
[tex]k = 6[/tex]
Divide by 2
[tex]k/2 = 3[/tex]
Square the expression
[tex](k/2)^2 = 9[/tex]
So, we have:
[tex]y = (x^2 + 6x + 9 - 9) + 10[/tex]
Rewrite as:
[tex]y = (x^2 + 6x + 9) -9+ 10[/tex]
[tex]y = (x^2 + 6x + 9) + 1[/tex]
Express as a perfect square
[tex]y = (x + 3)^2 + 1[/tex]
Hence, the equation in vertex form is [tex]y = (x + 3)^2 + 1[/tex], and the values of h & k are -3 and 1

find the slopes of the linear equations
Answer:
m is the slope.
b is the y intercept.
slope intercept is in the form: y = mx + b.
y - 4 = 3 (x - 2) [m = 3] [slope is 3]
y = 3/4x - 7 [m = 3/4] [slope is 3/4]
y + 8 = -6 (x - 1) [m = -6] [slope is -6]
y = -5x + 10 [m = -5] [slope is -5]
4x + 5y = 20 [m = -4/5] [slope is -4/5]
Explanation:
For all of these equations, make sure they are all in slope intercept form by isolating y completely, and getting it on the left side of the equation.
y - 4 = 3 (x - 2) → y - 4 = 3x - 6 → y = 3x - 2 → y = mx + b.y = 3/4x - 7 → y = mx + by + 8 = -6 (x - 1) → y + 8 = -6x + 1 →. y = -6x - 7 → y = mx + by = -5x + 10 → y = mx + b4x + 5y = 20 → 5y = -4x + 20 → y = -4/5x + 4 → y = mx + bSimplify the expression

The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t.
Write an inequality that can be used to represent the cost of a pizza that is at most $12.
What is the most number of toppings that a pizza can have and still be at most $12?
Answer:
5
Step-by-step explanation:
Solve the equation: 9.99+0.35_< 12
solving it would give you 5.7428571. You can just take the five.
The inequality is 12 ≥ 9.99 + n(0.35) and the most number of toppings are 6.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t.
To write an inequality that can be used to represent the cost of a pizza that is at most $12:
Let n be the extra toppings.
12 ≥ 9.99 + n(0.35)
To find the number of toppings that a pizza can have and still be at most $12:
12 ≥ 9.99 + n(0.35)
n(0.35) ≤ 2.01
n ≤ (2.01) / (0.35)
n ≤ 5.74
n ≤ 6
Therefore, the most number of toppings are 6.

Explain why when you reflect a point across the line y=x, the x−coordinate and the y−coordinate change places, and when you reflect a point across the line y = −x, the x−coordinate and the y−coordinate change places and their signs are changed.
Answer:
The (x,y) is like a mirror reflecting across the plane. When it moves it goes opposite (y,x). We move over the y axis and we get a negitive because of the negative cordinate plane.
