Answer: A) (-1, 3)
Step-by-step explanation:
When reflecting across the y-axis the y value of the point stays the same and the x values flips to it's opposite.
The point of A on ΔABC is (1, 3)
The x value is 1. The opposite value of 1 is -1 giving us the coordinates (-1, 3)

(a) The diagram shows four angles around a point
1. Write down an equation in x and y
2. Simplify your equation
3.Find y when x=65°
Answer:
Step-by-step explanation:
The degrees around a point = 360, so
1. x + 95 + 3y + 80 = 360 so
2. x + 3y = 185
3. 65 + 3y = 185 and
3y = 120 so
y = 40
Answer:
y=40
Step-by-step explanation:
sum of all 3 angles : 240
3y+240=360
3y=360-240=120
y=3÷120
y=40

What is the equation of a circle with center (7, 2) and radius 2?
Answer:
(x - 7)² + (y - 2)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (7, 2 ) and r = 2 , then
(x - 7)² + (y - 2)² = 2² , that is
(x - 7)² + (y - 2)² = 4 ← equation of circle

Answer:
Y=75x+125
Step-by-step explanation:
Your answer is correct. It is c. The equation is y=Mx+b where m is the slope and b is the y intercrept.
To get M (the slope), get the difference of y-y/x-x. You can use any value of y and x. So, 575-500/6-5=75/1 ot 75. Therefore 75 is m in the equation y=Mx+b.
To get b, you figure out what y is when x is 0. So, looking at the numbers, subtract 75 from 350, which means that y is 275 when x is 2. Subtract 75 again to get 200 (275-75) when x is 1. Subtract 75 one more time to get y when x is 0. 200-75=125. 125 is the y intercept.
Going back to the equation y-Mx+b. Fill in m and b. Y=75x+125.

Answer:
y=50 and z=60 (vertically opposite)
x+60+y=180
or x+60+50=180
or x+110=180
or x=70
Answer:
Step-by-step explanation:
a.x = 95 degree
reason = being vertically opposite angles
x + 145 degree = 180 degree
x = 180 -145
x=35 degree
reason = being linear pair
b.40 + x =90 degree
x = 90 - 40
x = 50 degree
reason = being perpendicular
y = x + 40
y = 50 + 40
y = 90 degree
reason = being vertically opposite angles
c.50 + 60 + x=180 degree
110 + x =180
x = 180-110
x = 70 degree
reason = being linear pair
z = 60 degree
reason = being vertically opposite angles
y = 50 degree
reason = being vertically opposite angles
d. x = 80 +10
x =90 degree
reason = being vertically opposite angles
y + x =180 degree
y + 90 =180
y = 180 - 90
y = 90 degree
reason = being linear pair

CAN ANYONE HELP ME WITH THIS PLEASE??
Answer:
The answer is A. 6.4 and 5.6 and D. 39 and 27.
Step-by-step explanation:
A. 6.4 and 5.6 = 1.6 and 1.4
6.4 / 1.6 = 4
1.4 * 4 = 5.6
So A is correct.
D. 39 and 27 = 13 and 9
39 / 13 = 3
9 * 3 = 27
So D is correct.
Hope this helps! :)
Consultant plans a survey to determine what % of the patients in a particular hospital were satisfied with the care they received after a major treatment. How many such patients should be surveyed so the margin of error for a 90% confidence interval is within .05? Suppose it is known from a past survey that such a % may be about 80%.
Solution:
Required margin of error = 0.05
Estimated population proportion p = 0.8
Significance level = 0.10
The [tex]\text{provided estimate population proportion}[/tex] p is 0.8
The significance level, α = 0.1 is [tex]z_c=1.645[/tex], which is obtained by looking into a standard normal probability table.
The number of patients surveyed to estimate the population proportion p within the required margin of error :
[tex]$n \geq p(1-p)\left(\frac{z_c}{E}\right)^2$[/tex]
[tex]$=0.8\times (1-0.8)\left(\frac{1.64}{0.05}\right)^2$[/tex]
= 173.15
Therefore, the number of patients surveyed to satisfy the condition is n ≥ 173.15 and it must be an integer number.
Thus we conclude that the number of patients surveyed so the margin of error of 90% confidence interval is within 0.05 are n= 174.

Question 4
Answer: Choice A) 3/10---------------------
Explanation:
There are 5 green, 9 red, and 6 blue. That makes 5+9+6 = 20 total marbles. Of this total, 6 are blue. The probability of picking blue is 6/20 = 3/10
==============================================================
Question 5
Answer: Choice C) x < 6---------------------
Explanation:
The open hole at 6 means we do not include this value as part of the shaded solution set. So we either have "less than" or "greater than".
We go with "less than" since the shaded region is to the left. This describes all values smaller than 6.
If you had "or equal to" as part of the inequality, then you would have a filled in circle at the endpoint.
Here's an equation of a line:

2y – 8x = -5
- 4y + x= -8
Step by step explaination
y-4x= -4
y= 4x-4

Solve for all solutions of p.
We are given the equation below:
[tex] \large{ {p}^{2} = \frac{9}{36} }[/tex]
Use the property below:
[tex] \large \boxed{ {x}^{2} = \frac{a}{b} \longrightarrow x = \pm \frac{ \sqrt{a} }{ \sqrt{b} } \: \: (a \geqslant 0 \: \: and \: \: b > 0)}[/tex]
From the equation:
[tex] \large{p = \pm \frac{ \sqrt{9} }{ \sqrt{36} } } \\ \large{p = \pm \frac{3}{6} \longrightarrow p = \pm \frac{1}{2} }[/tex]
Hence the answer is p = ± 1/2.
Answer
p = 1/2, -1/2p = ± 1/2Both answers work. The second answer is in the plus-minus form.
