3x + 2, x?, and 2x when x = 4
Answer:
[tex]3x+2 \ne x^2 \ne 2x[/tex] for [tex]x = 4[/tex]
Step-by-step explanation:
Given
Shape: Triangle
Dimension: 3x + 2, x^2 and 2x
[tex]x = 4[/tex]
Required
Determine if it has equal sides
To do this, we simply substitute 4 for x in the given dimensions
3x + 2
[tex]3x + 2 = 3 * 4 + 2[/tex]
[tex]3x + 2 = 12 + 2[/tex]
[tex]3x + 2 = 14[/tex]
x^2
[tex]x^2 = 4^2[/tex]
[tex]x^2 = 16[/tex]
2x
[tex]2x = 2 * 4[/tex]
[tex]2x = 8[/tex]
[tex]3x+2 \ne x^2 \ne 2x[/tex] for [tex]x = 4[/tex]

Answer:
y=-1x+8
Step-by-step explanation:
use slope formula y2-y1/x2-x1 to find the slope
10-5/-2-3
simplify
5/-5
simplify
-1
now you have to find the y-intercept using y=mx+b
y=-1x+b
plug either ordered pair in to find b, I am using (3,5)
(5)=-1(3)+b
simplify
5=-3+b
add 3 to both sides
b=8
now plug b into y=-1x+b to find the equation of the line
y=-1x+8

There were 35 students in a class. If 5/7 of the students were present on Monday, then how many students were NOT present on Monday.
Which is NOT an equivalent fraction to:3/4.

[tex] \tt : \implies Students \: present \: on \: Monday = \dfrac{5}{7} \times 35[/tex]

Now, we have to find students not present on Monday :
As, we have :
Total number of students = 35 Students present on Monday = 25[tex] \\ [/tex]
Therefore,
Students absent on Monday = 35 - 25 = 10

Please help.. Answer number 34 and 35. For number 34 find the measures of the numbered angles in each isosceles trapezoid. For number 35 find the measures of the numbered angles in each kite.
Answer:
33. m∠1 = 135°, ∠3 = 45°, ∠2 = 135°
34. m∠1 = 80°, m∠2 = 100°, m∠3 = 100°
35. m∠1 = 90°, m∠2 = 25°
Step-by-step explanation:
33. The given parameters of the isosceles trapezoid are;
The measure of one of the base angles = 45°
For an isosceles trapezoid, the base angles are equal, therefore, we have;
The measure of the other base angle = m∠3 = 45°
Similarly, m∠1 = m∠2
Also, we have;
The sum of the interior angles in a trapezoid = The sum of the interior angles in a quadrilateral = 360°
∴ 45° + m∠3 + m∠1 + m∠2 = 360°
By substituting the known values, we have;
45° + 45° + m∠1 + m∠2 = 360°
From m∠1 = m∠2, we have;
45° + 45° + m∠1 + m∠1 = 90° + 2·m∠1 = 360°
2·m∠1 = 360° - 90° = 270°
∴ m∠1 = 270°/2 = 135°
m∠1 = 135° = m∠2
Therefore, we have;
∠3 = 45°, ∠1 = 135°, ∠2 = 135°
34. The measure of the base angles = 80°
∴ The measure of the other base angle = m∠1 = 80°
m∠2 = m∠3
80° + m∠1 + m∠2 + m∠3 = 360°
∴ 80° + 80° + 2·m∠2 = 360°
m∠2 = (360° - (80° + 80°))/2 = 100°
m∠2 = 100° = m∠3
35. The kite comprises of two half isosceles triangles
The base angles of the right half isosceles triangle = 65°
The angle formed by the diagonals of the kite = 90° (Perpendicular diagonals theorem)
Therefore, m∠1 = 90°
The diagonals bisect the angles at the vertices (Kite theorem)
Therefore, we have;
65° + 90° + m∠2 = 180°
m∠2 = 180° - (65° + 90°) = 25°
m∠2 = 25°.
What is the output of the function when the input is 10? On the graph plot this point and label its coordinates
Answer:
Output value = 20
Step-by-step explanation:
Graph of any function is made up of two values → Values on x axis and Values along y axis.
x values represent the input values and y values represents the output values.
For every x value there is a y value because of which the data set is called to a function.
In other words, a function can't have two output values for a single input value.
If the input value of function is = 10
Then for x = 10, out value (along y axis) will be = 20
Therefore, Output value of the given function is 20.
