If (x-2,6)=(4,y+2)then the value of x=_____and y=____
x=6 , y = 4
Step-by-step explanation:
( x-2,6)=(4,Y+2)
this means; (x-2) &( 4) stands for" x "axis.
and( 6 )& (y+2) stands for y axis.
So, we can say( x-2)=X1 & (4)=X2 , (6)=Y1 & (y+2)=Y2
then; to Solve The Equation we use The Formula: X1=X2 for "X" And Y1=Y2 for "Y".
Solution: for "X" ; X1=X2
x-2= 4
x=4+2
x=6
For "Y" ; Y1=Y2
6 = y+2
y=6-2
y=4
finally check ; ( (x-2),6) = (4,(y+2) )
(6-2),6 = (4,(4+2) )
( (4),6) = (4,(6) )
(4,6) = (4,6)
so, X1 =X2 ; 4 = 4
Y1 = Y2 ; 6 = 6

B: (-1, 3)
C: (-1, -3)
D: (1, 3)
Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1
y=1+2=3
The distance between two stars is 9.0 x 10 to the power of -3 light years. A light year is equal to
5.88 x 10 to the power of 12 miles. What is the distance, in miles, between the two stars
Answer:
The distance between the two stars in miles is 5.292 * 10^10 miles
Step-by-step explanation:
Here, we want to make a conversion from light year to miles
To make this conversion, we simply are going to multiply the light year by the miles
Mathematically, we have this as;
9 * 10^-3 * 5.88 * 10^12
= 52.92 * 10^9
= 5.292 * 10^10 miles

Write the equation of the line that pass through the points below. Write your answer in Point-Slope Form or Slope-Intercept Form. Do NOT use any spaces in your answer.
(2, 17), (4, 7)
Equation:
Answer:
Please check the explanation.
Step-by-step explanation:
Given the points
(2, 17)(4, 7)Finding the slope between (2, 17), (4, 7)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:17\right),\:\left(x_2,\:y_2\right)=\left(4,\:7\right)[/tex]
[tex]m=\frac{7-17}{4-2}[/tex]
[tex]m=-5[/tex]
We know the Point-Slope Form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Here:
m is the slope(x₁, y₁) is the pointsubstituting the values m = -5 and the point (2, 17) in the Point-Slope Form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 17 = -5 (x-2)[/tex]
Thus, the answer Point-Slope Form is
[tex]y - 17 = -5 (x-2)[/tex]
It can be further simplified to write into the Slope-Intercept Form
[tex]y - 17 = -5 (x-2)[/tex]
y-17 = -5x+10
y = -5x+10+17
y = -5x+27
Thus, the answer in the Slope-Intercept Form (y=mx+b)
y = -5x+27 ∵Slope-Intercept Form → y=mx+b

Answer:
99,000
Step-by-step explanation:
since 3 times 10 to the power of 3 is 1000 and 10 to the power of 5 is 100000 the answer is 99,000
Answer: 97000 more
Step-by-step explanation:
10*10*10*10*10=100000 10⁵
10*10*10=1000*3=3000 10³
So 100000-3000= 97000 more

Which of the following equations is the correct representation of the graph below?
Find the x-intercept and the y-intercept of the line 2x-5y= -6
Answer:
Step-by-step explanation:
2x - 5y = 6
5y = 2x - 6
y = 2/5x - 6/5
y-intercept is -6/5
x-intercept is when you say that y = 0
and so 6/5 = 2/5x
x = 6/2 = 3

In 1995, the population of a town was 33,500. It is decreasing at a rate of 2.5% per decade.
a. Identify whether the function is a growth or decay function.
b. Write the function, f(n), that expresses the population of the town after (n) decades.
c. What is the population in the year 2025 to the nearest hundred?
Answer:
See belowStep-by-step explanation:
Initial date = 1995Initial population = 33500Decrease rate = 2.5% per 10 yearsa. It is a decay function as number of population is decreasing over time
b. f(n) = 33500*((100 - 2.5)/100)^n = 33500*(0.975)^n
c. In year 2025, n = (2025 - 1995)/10 = 3
f(3) = 33500*(0.975)^3 = 31100 rounded up
Find the measure of QS.
S9T 10 R 21 F 4x+5 Q
A. 35 B, 20 C. 27 D. 29
Answer:
C. 27
Step-by-step explanation:
((4x + 5) + 10)*10 = (21 + 9)*9 (two secants intersecting)
(4x + 5 + 10)*10 = (30)*9
(4x + 15)*10 = 270
40x + 150 = 270
40x = 270 - 150 (subtraction property of equality)
40x = 120
Divide both sides by 40
40x/40 = 120/40
x = 3
✔️QS = (4x + 5) + 10
Plug in the value of x
QS = 4(3) + 5 + 10
QS = 12 + 5 + 10
QS = 27

x/5 - g = a for x
how can i find x?
Answer:
X = 5a+5g
Step-by-step explanation:
Adding g on both sides gives:
X/5 = a+g
Now dividing 5 on both sides gives us the value of x which is:
X = 5(a+g)
Hence X=5(a+g) or X=5a+5g( multiplying by 5 gives us 5a and 5g)
From the top of tower, the angle of depression to a stake on the ground is 60°. The top of the tower is 80 feet above the ground. How far is the stake from foot of the tower?
Answer:
The stake is 80√3 ft or 138.56ft away
Step-by-step explanation:
let the distance from the stake to the foot of the tower=x
tan(60°)=x/80
x=80tan(60°)
x=80√3 ft
The distance of the stake from the foot of the tower is 46.189 feet.
What are trigonometric functions?Simply put, trigonometric functions—also called circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.
Given the angle of depression is 60°
60° is the angle from the stake to the top of the tower due to alternative angles,
height of tower = 80 feet
let the distance of the stake from tower be x
using tangent to find the distance,
tanФ = perpendicular/base
perpendicular = 80 feet
base = x
Ф = 60°
tan60 = √3
tan60 = 80/x
x = 80/1.732
x = 4.189 feet
hence stake is 46.189 feet from the tower.

Isaac works as a cook at a restaurant. He started this week with 800 potatoes. On Monday, he used 380 potatoes. On Tuesday, he used 270 potatoes. How many potatoes were left at the end of Tuesday?
Answer:
The number of Potatoes remaining is = 150
Step-by-step explanation:
From the information given above,
On first day of the week (Sunday),
Total potato = 800
The number used include:
Monday = 380
Tuesday = 270
Total potato used = Monday + Tuesday
= 380 + 270 = 650
Remaining Potato = 800 - 650 = 150
