What’s the x on this triangle ?
Answer:
x = 5
Step-by-step explanation:
x is the length of the hypotenuse of this triangle. The length of one of the legs of the triangle is 3" and that of the other leg is 4".
Applying the Pythagorean Theorem: x^2 = 3^2 + 4^2, or 25
Thus, the length x is +√25, or 5.
x = 5

What is the point-slope form of a line with slope 4/5 that contains the point
(-2, 1)?
A. y+1 = 4/5(x-2)
B.y+1 = 4/5(x + 2)
C. y-1 = 4/5 (x+2)
D. y-1 =4/5 (x-2)
SUBMIT
Awnser: Its D uhm yea...
Step-by-step explanation:
The point-slope form of a line is (y-y1)=m(x-x1). Therefore, option C is the correct answer.
Given that, slope (m)=4/5 and the point on line=(-2, 1).
What is the point-slope form of a line formula?A slope is, a numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it (“slope equals rise over run”).
The point-slope form of a line formula is (y-y1)=m(x-x1).
Now, (y-1)=4/5(x+2).
Therefore, option C is the correct answer.

3x - y = -1
-3x -y = 5
x = y =
Answer:
Step-by-step explanation:
Step 1: Solve3x-y=-1 for y
3x-y=-1
3x-y+-3x=-1+-3x (add -3x to both sides)
-y=-3x-1
-y/-1=-3x-1/-1 (divide both sides by -1)
y=3x+1
Step 2: 3x+1 for y in -3x-y=5
-3x-y=5
-3x-(3x+1)=5
-6x-1=5 (simplify both sides of the equation)
-6x-1+1=5+1 (add 1 to both sides)
-6x=6
-6x/-6=6/-6 (divide both sides by -6)
x=-1
Step 4: Substitute -1 for x in y=3x+1
y=3x+1
y=(3)(-1)+1
y=-2
ANSWER: x=-1, and y=-2
Think About the Process You have 20 quarters. You find 40% more quarters in your room. Then
you go shopping and spend 75% of the total number of quarters. Write an expression to represent
the total number of quarters you take with you shopping. Calculate, in dollars, the amount of money
you have left.
What expression represents your total number of quarters?
O A. 20 +(20 - 0.75)
OB. 20+ (20 = 40)

Brandon bought a jacket on sale for $36. If the jacket originally cost $60, what was the percentage discount for the cost of the jacket?
Answer:
40% discount
Step-by-step explanation:
To find this remember the formula [tex]\frac{discount amount}{original price} = \frac{percent discount}{100}[/tex]
To find the discount amount subtract $36 from $60 which is $24.
[tex]\frac{24}{60} = \frac{x}{100}[/tex] next you have to cross multiply
24*100 = 2400 and 60*x = 60x
Now you have the equation 2400 = 60x
Divide both sides by 60 to isolate the variable
x = 40

Which point could be removed in order to make the relation a function?
{(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)}
(8, 3)
(3, –6)
(–1, 8)
(–4, –2)
Answer:
(3, –6)
Step-by-step explanation:
A function is a relation where one input is assigned to exactly one output.
This means that no inputs must be repeated in the relation.
(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)
The input of '3' repeats in the relation.
By removing (3, -6), we can make the relation given a function.
