Answer:
m<1 = 39
m<2 = 51
Step-by-step explanation:
For this problem, you need to understand that a little square in the bottom of two connecting lines represents a right-angle (an angle this 90 degrees). This problem, gives you two relationships for angle 1 and angle 2 within a right-angle. Using this information, we can solve for the measures of the two angles.
Let's write the two relations:
m< 1 = 3x
m< 2 = x + 38
And now let's right an equation that represents the two angles to the picture:
m<1 + m<2 = 90
Using this information, let's substitute the expressions we have for the two angles and solve for x. Once we have the value of x, we can find the measure of the two angles.
m< 1 + m< 2 = 90
(3x) + (x + 38) = 90
3x + x + 38 = 90
x ( 3 + 1 ) + 38 = 90
x ( 4 ) + 38 = 90
4x + 38 = 90
4x + 38 - 38 = 90 - 38
4x = 90 - 38
4x = 52
4x * (1/4) = 52 * (1/4)
x = 52 * (1/4)
x = 13
Now that we have the value of x, we simply plug it back into our expressions for the m<1 and m<2.
m<1 = 3x = 3(13) = 39
m<2 = x + 38 = 13 + 38 = 51
And we can verify this is correct with the relational equation:
m<1 + m<2 = 90
39 + 51 ?= 90
90 == 90
Hence, we have found the values of m<1 and m<2.

What is square root ?
In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16. The square root of any number can be expressed using the formula: √y = y½. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.
Given,
[tex]\sqrt{128}[/tex]
we divide the number 128 by 2 four times, we get
= [tex]\sqrt{8*2*2*2*2}[/tex]
= 2*2[tex]\sqrt{8}[/tex]
=4 [tex]\sqrt{8}[/tex]
Therefore, 4 [tex]\sqrt{8}[/tex] is the correct answer

Conjecture: Twice the number of units in the length of any side of a rectangle is equal to the number of square units in the area of the rectangle.
The area of ABDE is 4 and 2 X AB = 4
The area of ABCF is 2 and 2 x BC = 2.
The area of ABCF is 2 and 2 x AB = 4
The area of ABDE is 4 and 2 x BD = 4
The statement proves that the conjecture is
Answer:
The area of ABCF is 2 and 2 × AB = 4
The statement proves that the conjecture is false
Step-by-step explanation:
A conjecture is a proposition or conclusion that is presumed to be true or correct but which is based on incomplete details or information
Given the length of the sides of rectangle ABDE, we have;
Length AB = 2 units
Length DE = 2 units
The area of ABDE = 2 × 2 = 4 unit²
Therefore, the area of the rectangle ABDE is equal to 2 × the length of either AB or DE
However, the are of rectangle ABCF = 2 × 1 = 2 unit²
While the area of rectangle 2 × the length of side AB = 2 × 2 = 4 unit², which is not equal to the number of square units in the area of the rectangle.
Therefore;
The area of ABCF is 2 and 2 × AB = 4
The statement (above) proves that the conjecture is false.

give a numerical example that shows these are not the same expressions. 2(n+5) and 2n+5
Answer:
The two are different expressions because when you distibute, you multiply all terms inside the parenthesis with the 2 in the first one: 2(n+5) = 2n + 10.
2n + 10 ≠ 2n + 5.
Step-by-step explanation:
Answer: Any number that isn’t 1, 2, -1, or -2 I believe.
Step-by-step explanation: In the first expression, you have to distribute the 2, making it equal to 2n + 10, whereas the first is just 2n + 5.
For example if you were to plug the number 3 into this, you would have 2(3+5), which is 2(8) = 16. Versus the other side, 2(3)+5 = 11

Lorenzo has 4 packages of granola bars. Each package has 10 bars. He eats one bar from each package.
Answer:
4x10-4=36
Step-by-step explanation:
Lorenzo ate 1 bar from each. so 36 is left.
Answer:
4 × 10 - 4 = 36 granola bars
Step-by-step explanation:
4 packages with 10 bars each means 40 bars (4 packages × 10 bars each = 40 bars total)
one bar from each package
there are 4 packages so if he eats only one from each then he eats 4 bars total
40 bars total - 4 bars he ate = 36 bars left over

A line passes through the points (−4,−9)
and (−2,−6) What is the equation of the line in Slope-Intercept Form?
Answer:
D. [tex] y - 5= 3(x - 1) [/tex]
B. [tex] y = \frac{3}{2}x - 3 [/tex]
Step-by-step explanation:
Problem 1:
Point-slope form equation is given as [tex] y - y_1 = m(x - x_1) [/tex], where, (x1, y1) is a point on the line, and m = slope.
Find the slope of the line of the graph given, using 2 points on the line, points (0, 2) and (1, 5).
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{0 - 1} = \frac{-3}{-1} = 3 [/tex]
Substitute (x1, y1) = (1, 5) and m = 3 into [tex] y - y_1 = m(x - x_1) [/tex]
[tex] y - 5= 3(x - 1) [/tex]
The answer is D.
Problem 2:
Slope-intercept equation takes the form: [tex] y = mx + b [/tex], where, m = slope, and b = y-intercept.
Find m and b.
Given, points (−4,−9) and (−2,−6),
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-6 -(-9)}{-2 -(-4)} = \frac{3}{2} = \frac{3}{2} [/tex]
Substitute x = -2, y = -6, and m = ³/2 into [tex] y = mx + b [/tex], to find b:
[tex] -6 = \frac{3}{2}(-2) + b [/tex],
Subtract b from both sides
[tex] -6 = -3 + b [/tex]
Add 3 to both sides
[tex] -6 + 3 = b [/tex]
[tex] -3 = b [/tex]
[tex] b = -3 [/tex]
Substitute m = ³/2, b = -3 into [tex] y = mx + b [/tex]
[tex] y = \frac{3}{2}x + (-3) [/tex]
[tex] y = \frac{3}{2}x - 3 [/tex]

The slope of a line is the ratio of the
A.
vertical change to the horizontal change between any two points on the line.
B.
x-intercept to the y-intercept.
C.
y-intercept to the x-intercept.
D.
horizontal change to the vertical change between any two points on the line.
Answer:
A.
vertical change to the horizontal change between any two points on the line.
Step-by-step explanation:
slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . This simple equation is called the slope formula.
The slope of a line is the ratio of the : A. Vertical change to the horizontal change between any two points on the line.
The slope of a line is the gradient of a line and it describes (represents) both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is calculated by using this formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Hence, the slope of a line is the ratio of the change in y-axis (vertical) to the change in x-axis (horizontal) of a line.
Additionally, the standard form of an equation of line is given by the following formula;
[tex]y = mx + b[/tex]
Where:
x and y are the points. m is the slope. b is the intercept.In conclusion, the ratio of the vertical change to the horizontal change between any two points on the line is the slope of a line.
