Answer:
( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )
Step-by-step explanation:
[tex]3x^{2}[/tex] - 2[tex]x[/tex] - 5
(Multiply 3 from [tex]3x^{2}[/tex] with -5)
Product = -15
Sum = -2
(3 times - 5 gives the product '-15' and 3 plus -5 gives the sum -2)
[tex]3x^{2}[/tex] + 3[tex]x[/tex] - 5
3[tex]x[/tex] ( [tex]x[/tex] + 1 ) - 5 ( [tex]x[/tex] + 1 )
= ( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )

Answer:
The solution of the first image is: b = √48
The solution of the second image is: c = √125
Step-by-step explanation:
Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.
For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:
A^2 + B^2 = H^2
Where H is the side that is opposite to the right angle (the angle of 90°)
In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.
We want to find the value of b, that is the other cathetus.
Then we have:
4^2 + b^2 = 8^2
b^2 = 8^2 - 4^2
b^2 = 48
b = √48
Second image:
in this case, c is the hypotenuse, a and b are the cathetus.
We know that:
a = 5, b = 10
Then we have the equation:
a^2 + b^2 = c^2
Now we can replace the above values:
5^2 + 10^2 = c^2
25 + 100 = c^2
125 = c^2
√125 = c

Which equation represents this situation? y = 1.25x ) Which graph represents the situation?
The second graph represents the situation y=1.25x which has slope 1.25.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is y= 1.25x
Slope is 1.25
Now let us plug in (1, 1.25) in the equation
1.25=1.25(1)
Hence, the second graph represents the situation y=1.25x which has slope 1.25.

Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at? Include the steps you used to solve the problem and your answer
Answer:

Step-by-step explanation:
Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?
This is a simple interest question
The formula to find the rate is given as:
Equation:
r = (1/t)(A/P - 1)
t = time = 4 years
P = Principal = $12500
I = Simple Interest = $1500
A = Total Amount = Principal + Simple Interest = $12500 + $1500
= $14000
Calculation:
Solving our equation:
r = (1/4)((14000/12500) - 1) = 0.03
r = 0.03
Converting r decimal to R a percentage
R = 0.03 * 100 = 3%/year
How many solutions are shown by the graph of the quadratic function? A zero B one C two D three

Answer:
x = 6
Step-by-step explanation:
The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).
a² + b² = c²
(8)² + b² = (10)²
64 + b² = 100
b² = 100 - 64 = 36
b = ±[tex]\sqrt{36}[/tex]
b = ± 6
But we know that distance is always positive, so
b = 6
I have used b in place of x if you are confused about the variable usage.

What is the rule that describes a reflection across the line y = x?
rx = y(x, y) →
Answer:
D I think
Step-by-step explanation:
GH=5 5; <H = 90
1. The mapping of the vertices of ΔDEF will be;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
2. The rule of the reflection across the line y = x is;
[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]
What is Refection?
Reflection is a type of transformation that flip a shape in mirror line, so that each point is the same distance from the mirror line as its reflected point.
Given that;
The coordinates are,
D = (2, –4)
E = (1, –1)
F = (5, 1)
Now,
By the given image,
The mapping of the vertices of ΔDEF is;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
And, The rule of the reflection across the line y = x is;
[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]
Because in the image its shows the line of reflection.
Therefore,
1. The mapping of the vertices of ΔDEF will be;
D(2, –4) → D' (-4, 2)
E(1, –1) → E' (-1 , 1)
F(5, 1) → F' (1, 5)
2. The rule of the reflection across the line y = x is;

1. 2(x + 5) = 3x + 1
2(x + 5) = 3x + 1
Distribute the 2
2x + 10 = 3x + 1
-1 -1
2x + 9 = 3x
-2x -2x
9 = x
2. 3y - 4 = 6 - 2y
3y - 4 = 6 - 2y
+4 +4
3y = 10 - 2y
+2y +2y
5y = 10

question: solve the solution using substitution.
Answer:
x = -3
y = -8
Step-by-step explanation:
2y = x - 13
3x = y - 1; let y = 3x + 1
substitute to solve for 'x':
2(3x + 1) = x - 13
6x + 2 = x - 13
5x + 2 = -13
5x = -15
x = -3
solve for 'y':
3(-3) = y - 1
-9 = y - 1
-8 = y
Answer:
(-3,-8)
Step-by-step explanation:
Get one of the variables by themself.
3x = y-1
y = 3x+1
Plug that equation into the other one
2(3x+1) = x-13
Distribute the 2 to 3x+1
6x+2 = x-13
Combine like terms
6x+2 = x-13
-x -x
5x+2 = x-13
-2 -2
5x = -15
Divide by 5 on both sides
5x = -15
÷5 ÷5
x = -3
Find y
3(-3) = y-1
-9 = y-1
+1 +1
y = -8

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13
