Which number line shows the solution to -3- (-1)? (1 point)
o
Answer:
The third choice gives the correct sequence.
Step-by-step explanation:
The Number Line
To represent numbers in the line, we use arrows starting from the mark for zero up to the given number. If the number is positive, the arrow points to the right and if the number is negative, the arrow points to the left.
The number -3 must be represented as an arrow to the left side of length 3. Subtracting something from the number should also point to the left side, but if the number is negative, then the new arrow points to the right side.
To subtract -1, the arrow should point to the right starting from -3
The third choice gives the correct sequence.
A line passes through (10,2) and (14,-22). Write the equation of the line in standard form.
Answer:
The equation of the line in standard form is:
[tex]6x + y = 62[/tex]
Step-by-step explanation:
Given the points
(10,2)(14,-22)Determining the slope between (10, 2) and (14, -22)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(10,\:2\right),\:\left(x_2,\:y_2\right)=\left(14,\:-22\right)[/tex]
[tex]m=\frac{-22-2}{14-10}[/tex]
[tex]m=-6[/tex]
The point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointsubstituting the values m = -6 and the point (10, 2) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 2 = -6(x - 10)[/tex]
[tex]y - 2 = -6x +60[/tex]
adding 2 to both sides
[tex]y-2+2 = -6x + 60 + 2[/tex]
[tex]y = -6x + 62[/tex]
We can write the equation in the standard form such as
Ax + By = C
Thus,
[tex]y = -6x + 62[/tex]
adding -6x to both sides
[tex]6x + y = -6x + 62 + -6x[/tex]
[tex]6x + y = 62[/tex]
Therefore, the equation of the line in standard form is:
[tex]6x + y = 62[/tex]

Please help if you can.
Answer:
1) Slope of the line [tex]y = \frac{-3}{2}[/tex]
2)Slope of the line m = 2
3) slope of the line m = -5
Step-by-step explanation:
Step(i):-
Given that equation of the straight line 3 x+2 y =0
The slope - intercept form y = mx +c
2 y = - 3x
[tex]y = \frac{-3}{2} x[/tex]
Slope of the line [tex]y = \frac{-3}{2}[/tex]
Step(ii):-
Given that equation of the straight line 2 x- y = 3
The slope - intercept form y = mx +c
y = 2x -3
slope of the line m = 2
Step(iii):-
Given that equation of the straight line 5 x + y = 10
The slope - intercept form y = mx +c
y = -5x +10
slope of the line m = -5

x = 3(12/0.3) = 120
There are about 120 inches in 3 meters.
Compute $\sqrt{0.5625}$. Express your answer as a decimal.
Answer:
0.75
Step-by-step explanation:
We have\begin{align*}
\sqrt{0.5625} &= \sqrt{\dfrac{5625}{10000}}\\
&= \dfrac{\sqrt{5625}}{\sqrt{10000}}\\
&= \dfrac{\sqrt{25\cdot 225}}{100}\\
&= \dfrac{\sqrt{25}\cdot \sqrt{225}}{100}\\
&=\dfrac{5\cdot 15}{100}\\
&=\boxed{0.75}.\end{align*}
The Square root of 0.5625 is 0.75.
What is Square Root?A number can be obtained by multiplying the square root of that integer by itself. The word "square root" is represented by the symbol "sqrt"—square root of, end square root. The opposite of squaring an integer is finding its square root.
Given:
We have to find the square root of (0.5625).
So, 5625 can factorize as
= 5625
= 5 x 5 x 5 x 5 x 3 x 3
Now, making the pairs as
= (5 x 5) x (5 x 5) x (3 x 3)
= 5 x 5 x 3
= 75
So, the root of 0.5625 in decimal is 0.75.

b.
$118,750
d.
$62,500
Answer:
a.
$6,250
Step-by-step explanation:
Finances 95% of the loan.
So you have to pay 100% - 95% = 5% of the loan.
The amount of the home is listed at $125,000.
You have to pay 5% of this. So
0.05*125000 = $6,250

Answer:
rhombussquarerectanglesquareStep-by-step explanation:
It is convenient to look at the differences of end point coordinates.
For a square, the values will be interchanged and one negated.
For a rhombus, the dot product will be zero.
For a rectangle, their sum of squares (diagonal length) will be the same.
__
1. VX = X - V = (11 -3, 4 -0) = (8, 4)
WY = Y -W = (8 -6, 0 -4) = (2,-4)
The numbers are different, so it is not a square. The dot product is ...
(8)(2) + (4)(-4) = 16 -16 = 0
So, the figure is a rhombus.
__
2. LN = (6 -1, 3 -2) = (5, 1); MP = (4 -3, 0 -5) = (1, -5)
The figure is a square.
__
3. HK = (12 -1, 0 -3) = (11, -3); JL = (3 -10, -3 -6) = (-7, -9)
The lengths of the diagonals are ...
√(11^2 +3^2) = √130 and √(7^2 +9^2) = √130
Diagonals are the same length, so the figure is a rectangle.
__
4. EG = (-2 -(-4), -1 -3) = (2, -4); FH = (-5 -(-1), 0 -2) = (-4, -2)
The figure is a square.

By transitive property we have shown that if angles ∠A + ∠B = ∠B + ∠C, then ∠C = ∠A.
What are Angles?An angle is formed when two straight lines or rays meet at a common endpoint.
We are given that ∠A + ∠B = ∠B + ∠C.
We can simplify this expression by subtracting ∠B from both sides to obtain ∠A = ∠C.
This is because ∠B + ∠C - ∠B simplifies to ∠C, and ∠B + ∠A - ∠B simplifies to ∠A.
Therefore, ∠A = ∠C, which proves the statement.
We can also use the transitive property of equality to prove this statement.
∠A + ∠B = ∠B + ∠C
we can subtract ∠B from both sides to obtain ∠A = ∠C.
Then, using the transitive property of equality, we can substitute ∠C for ∠A to obtain ∠C = ∠A, which proves the statement.
Therefore, we have shown that if angle ∠A + ∠B = ∠B + ∠C, then ∠C = ∠A.
