Answer:
55
Step-by-step explanation:
Angle C = Angle D (Corresponding Angles)
Therefore, BD//AC
Angle A = Angle B (Corresponding Angles)
=>6x-15=5x-1
=>6x-5x=-1+15
=>x=14
Angle B=5x-1
=5(14)-1
=70-1
=69
Angle D=4x
=4(14)
=56
Angle E=180-(Angle D+ Angle B) [Angle Sum Property]
=180-(69+56)
=180-125
=55
can you answer this please
Answer:
C
Step-by-step explanation:
y=mx+b where m =slope and b= y intercept
m=y-y/x-x or 3-1/1-0 or 2
B is where the line crosses the x axis or 1
So y=2x+1
There are values of iso that sin t= 6 and cost=.8
O A True
B. False
Need help plzzz
Answer:

Plsss hellppp I give brainliest but earn it
Answer:
3
Step-by-step explanation:
let the no of people who share the meal be x
each member paid $17
total cost of meal=$51
so ur equation is
$17x=$51
x=$51/$17(here $ and $ also gets cancel)
x=3
therefore three menber shared the meal.
Note:when in multiplication when u transfers the number to other side it changes into mltiplication.For example
$17=$51
here $17 is multiplied with x and when we bring $17 to right hand side it divides $51.
Answer:
[tex]17x = 51 \\ \frac{17x}{17} = \frac{51}{17} \\ x = 3[/tex]
Step-by-step explanation:
The error was that the learner subtracted both sides instead of dividing both sides. The student was supposed to divide both sides by 17 to get the answer.

illustrate the solution of the inequality ( x - 5) ( x + 5)≥ 0. on the number line
Answer: The diagram is shown below
==============================================================
Explanation:
If you graphed y = (x-5)(x+5) on the xy grid, then you'd see a parabola forming. This parabola has x intercepts at -5 and 5. The parabola opens upward.
If x < -5, then (x-5)(x+5) is positive. Let's say x = -6
(x-5)(x+5)
(-6-5)(-6+5)
(-11)(-1)
11
So if x = -6, then y = (x-5)(x+5) becomes 11 which is positive. If you picked any other value less than -5, then (x-5)(x+5) is positive.
Similarly, if x > 5, then (x-5)(x+5) is also positive for similar reasoning. Try x = 6 to see what happens. The actual value itself doesn't matter. All we care about is if the result is positive or negative.
It's only when -5 < x < 5 that (x-5)(x+5) is negative. Consider x = 0 which is between -5 and 5
Plugging x = 0 leads us to
(x-5)(x+5)
(0-5)(0+5)
(-5)(5)
-25
Showing that (x-5)(x+5) is negative on the interval -5 < x < 5
---------------------------------------------
Going back to the original inequality, we want to know when (x-5)(x+5) is positive or 0
We found that (x-5)(x+5) is positive when x < -5 or when x > 5
(x-5)(x+5) is equal to zero when x = -5 or x = 5
So overall, the solution we want is [tex]x \le -5 \ \text{ or } \ x \ge 5[/tex]
To graph this on a number line, we plot closed filled in circles at -5 and 5. Then we shade everything that is not between these two circles (so we shade everything except the interval -5 < x < 5).
The graph is below.

Solve 5x2 = 180 algebraically.
Answer:
x = ±6
Step-by-step explanation:
5x^2 = 180
Divide each side by 5
5x^2/ 5 = 180/5
x^2 = 36
Take the square root of each side
sqrt(x^2) = ± sqrt(36)
x = ±6
Answer: x = 6 or x = -6
Step-by-step explanation: First, isolate the x squared by dividing both sides by 5 to get x² = 36. Now, since x is squared, we simply take the square root of both sides of the equation to get x by itself.
When we take the square root of both sides of an equation,
we must always make sure to use plus or minus!
So x = ±5 and you can write your answer as the solution set {6, -6}.

Write the equation in standard form for the circle with center (0, -8) and radius 6.
Answer:
(x)^2 + (y+8)^2 = 36
Step-by-step explanation:
The standard form for an equation for a circle is
(x-h)^2 + (y-k)^2 = r^2 where ( h,k) is center of the circle and r is the radius
(x-0)^2 + (y- -8)^2 = 6^2
(x)^2 + (y+8)^2 = 36
Find the value of the following expression using suitable properties of whole numbers
and name the property used.
789 × 175 – 75 × 789
Given:
The expression is:
[tex]789\times 175-75\times 789[/tex]
To find:
The value of the given expression by using the suitable properties of whole numbers.
Solution:
We have,
[tex]789\times 175-75\times 789[/tex]
Using the commutative property of multiplication, we get
[tex]789\times 175-75\times 789=789\times 175-789\times 75[/tex]
Using the distributive property of addition over multiplication, we get
[tex]789\times 175-75\times 789=789\times (175-75)[/tex]
[tex]789\times 175-75\times 789=789\times 100[/tex]
[tex]789\times 175-75\times 789=78900[/tex]
Therefore, the value of the given expression is 78900.
A jazz concert brought in $167,000 on the sale of 8,200 tickets. If the tickets sold for $15 and $25 each, how many of each type of ticket were sold?
Answer:
x=3800, y=4400
Step-by-step explanation:
X+y=8200 equation 1
15x+25y=167000 equation 2
x=8200-y isolate x in equation 1
15(8200-y)+25y=167000 substitute value of x from equation 1 into equation 2
123000-15y+25y=167000
10y=44000
y=4400
solve for x by inserting y value into either equation.
x+y=8200
x+4400=8200
x=3800
Check answer:
15x+25y=167000
15(3800)+25(4400)=167000
57000+110000
167000=167000

Answer:
they are NOT similar!
Step-by-step explanation:
the angles are not conguent or they are not the same in words
the don't add up with the same sum of angles,
so your explanation would be:
45 plus 29 has a sum of 74 for the right triangle and the left triangle has angles 106 degrees plus 29 degrees with a sum of 135 degrees, there-fore the triangles aren't similar because the angles are not equal to each other
9514 1404 393
Answer:
∆AFN ~ ∆SHE . . . . AA~
Step-by-step explanation:
The third angle in triangle HSE is ...
180° -45° -29° = 106°
This means two angles in ∆SHE match two angles in ∆AFN. (106° and 29°) The triangles are similar by AA~.
Listing vertices in order of smallest-to-largest angles, the similarity statement is ...
∆AFN ~ ∆SHE . . . . AA~
Person 1 can do a certain job in twenty-one minutes, and person 2 can do the same job in twenty-eight minutes. When
completing the job together, which expression would be used to represent the amount of work done by person 1?
A. 21
B. X/21
C. 21x
D. 1/21
Answer:
C) x/21
Step-by-step explanation:
Since Person 1 can complete the entire job (100% = 1/1 = 1) in 21 minutes, this person can complete 1/21 of the job per minute. This is Person 1's rate. If x is the amount of time it takes both people together to finish the job, then the amount of work Person 1 does would be (1/21)(x) = x/21.

Given:
The table of values.
To find:
The function for the given table.
Solution:
From the given table it is clear that the y-values are same as the corresponding x-values. It means y is directly proportional to x with 1 as a constant of proportionality.
Mathematically, it can be defined as:
[tex]y=1\times x[/tex]
[tex]y=x[/tex]
Substitute [tex]y=f(x)[/tex] in the above equation to find the required function.
[tex]f(x)=x[/tex]
Therefore, the correct option is A.
