In parallelogram ABCD shown below angle DAC = 98 and angle ACD =36. What is the measure of angle B? Explain why!
Step-by-step explanation:
m < D = 180- ( 98 + 36 )= 46
m < D = m < B = 46
The measure of angle B is : 46°
What is a parallelogram?A parallelogram is a quadrilateral with four sides and four angles.
The opposite sides of this parallelogram are parallel and the opposite angles are equal.
Analysis:
From the definition above, a parallelogram has opposite angles equal, which means ∠D = ∠B
Consider ΔACD
∠A + ∠C + ∠D = 180( angles in a triangle)
∠D + 98 + 36 = 180
∠D + 134 = 180
∠D = 180 - 134 = 46°
Therefore ∠B = 46°
In conclusion, ∠B is 46° because it is an opposite angle to D and opposite angles of a parallelogram are equal.

Step-by-step explanation:
Employee annual wages at a plant rose steadily, but very gradually, from one year to the next during one 5-year period. The factory owner wants to show that worker's wages are rising rapidly. Examine the following charts and decide which graph the factory owner would want to use and why.
a. The employee representative would want to use Graph B to show how much the employee wages have gained over the 5-year period.
b. The employee representative would want to use Graph B to show the decrease in slope.
c. The employee representative would want to use Graph A to show that wages have been a constant level doe the past 5-year period.
d. The employee representative would want to use Graph A to show that wages are rising minimally because Graph A appears to show the wages increasing at a much slower rate than Graph B.
Answer: The factory owner would want to use Graph B to show the rapid rise in his employees wages because Graph B shows greater increase in slope
Step-by-step explanation:
The question and the options are mismatched. Answer to the question is given above.
The factory owner would like to show that worker's wages are rising rapidly even though they are not.
The factory owner's best bet therefore is to use Graph B because it has a greater slope which might fool people into believing that the wage rates are rising rapidly which is what led to the greater increase in slope size.
The options most probably allude to a question asking what graph an employee representative would use to show that the wages are not increasing rapidly and the answer to that would be option D because graph A has a smaller slope.
Consider the equation 2x +2y =8
Answer:
in slope intercept form it would be y = -x + 4
Step-by-step explanation:
your equation: 2x +2y =8
subtract 2x from both sides: 2y = -2x + 8
divide both sides by 2: y = -x + 4

Is (0,0) a solution to this system?
y ²x²-4
y< 2x-1
A. No. (0,0) satisfies y 42-4 but does not satisfy y< 2x-1.
B. No. (0,0) does not satisfy either inequality.
C. No. (0,0) satisfies y< 2x- 1 but does not satisfy yz 22.4.
O D. Yes. (0,0) satisfies both inequalities.
Answer:
A. Solution to [tex]y \ge x^2 - 4[/tex] but not to [tex]y < 2x - 1[/tex]
Step-by-step explanation:
Given
[tex]y \ge x^2 - 4[/tex]
[tex]y < 2x - 1[/tex]
Required
Is [tex](0,0)[/tex] a solution?
[tex](0,0)[/tex] implies that:
[tex]x = 0\ and\ y = 0[/tex]
To check if it is a solution or not, we simply substitute 0 for x and for y in the given inequalities
[tex]y \ge x^2 - 4[/tex] becomes
[tex]0 \ge 0^2 - 4[/tex]
[tex]0 \ge 0- 4[/tex]
[tex]0 \ge - 4[/tex]
This solution is true
[tex]y < 2x - 1[/tex] becomes
[tex]0 < 2 * 0 - 1[/tex]
[tex]0 < 0 - 1[/tex]
[tex]0 < - 1[/tex]
This solution is not true because 0 is greater than 1.
Hence, option (A) is correct
