Answer:
(10, -8)
Step-by-step explanation:
Answer:
solution given:
G(x1,y1)=(-2,2)
H(x2,y2)=(x,y)
Mid point M(a,b)=(4,-3)
we have
(a,b)=((x1+x2)/2,(y1+y2)/2)
(4,-3)=((-2+x)/2,(2+y)/2)
comparing corresponding value
4=(-2+x)/2
8+2=x
x=10
again
(2+y)/2=-3
2+y=-6
y=-6-2
y=-8
So coordinates of H is (10,-8).

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [
Answer:
y = 4x+3
Step-by-step explanation:
The equation in point slope form is expressed as y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
If a line is parallel to y = 4x + 1, the slope of the line m = 4
Substitute m = 4 and the point (-2, -5) into the equation above;
y - (-5) = 4(x - (-2))
y+5 = 4(x+2)
y+5 = 4x+8
y = 4x+8-5
y = 4x + 3
Hence the equation of the line is y = 4x+3

The test will cover 120 pages in his textbook. He has read only 36 pages. If he plans to read an equal amount every day of the week to finish the 120 pages, how much must read each day?
Answer:
He must read each day=12 pages
Step-by-step explanation:
We are given that
Total number of pages in textbook=120
He has read number of pages=36
Number of days in a week=7
We have to find the number of pages read each day to finish 120 pages in a week.
Number of pages remaining for reading=120-36
Number of pages remaining for reading=84
Now,
Number of pages read each day=[tex]\frac{84}{7}[/tex]
Number of pages read each day=12
Hence, he must read each day=12 pages
solve 2x+6=34 i have no idea pls exsplain and help me :)
Answer:
14
Step-by-step explanation:
okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this
so you’re gonna start off by separating the 2x from the 6=34.
now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)
now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.
2 x 14 + 6 = 34?
2 x 14 = 28 + 6 = 34.
34 = 34
so, x is 14. hope this helped!

write the linear equation below in the function notation
y=2x-5
Answer:
f ( x ) = 2 x + 5
Step-by-step explanation:
Function notation is a system of representing functions.
y = 2x – 1
x + y = 2
Answer:
x = 1, y = 1
Step-by-step explanation:
plug y = 2x - 1 into the equation x + y = 2:
[tex]x + (2x - 1) = 2\\3x - 1 = 2\\3x = 3\\x = 1[/tex]
plug that into the equation y = 2x - 1
[tex]y = 2*1-1\\y=2-1\\y=1[/tex]

(8x + 3)(2^2+ 8x +9)
Answer:
64x²+128x+39
Step-by-step explanation:
(8
Answer:
First distribute (8x + 3) into (2^2+ 8x +9)
16x^3 + 64x^2 + 72x + 6x^2 + 24x +27
Then we'll order the pairs from highest to lowest degree
16x^3 + 64x^2 + 6x^2 + 72x + 24x + 27
Then we'll add up the like terms
16x^3 + 70x^2 + 96x + 27
That should be your final answer simplified.

(b) Find d when c = 15
Answer:
we have
C = 1.5d
or
d=C/1.5
Step-by-step explanation:
when d is 12
C=1.5×12=18
when c=15
d=15/1.5=10

The sum of 6.7 and a number is negative. What is a possible value for that number? Explain.
Answer:
The number must be greater than 6.7. Thus, the sum will be negative.
For example, the number could be 7.
6.7 - 7 = -0.3
The number can be in the range - x ∈ (- ∞ , - 6.7)
We have - the sum of 6.7 and a number is negative.
We have to determine the possible value of that number.
For what range of values of x, the given function is equals to a negative value -y = f(x) = 2x + 10For f(x) to be negative -
f(x) < 0
2x + 10 < 0
2x < - 10
x < - 5
x ∈ (- ∞ , - 5)
According to the question, we have - the sum of 6.7 and a number is negative.
Now -
6.7 + x < 0
x < 6.7
x ∈ (- ∞ , - 6.7)
Hence, the number can be in the range - x ∈ (- ∞ , - 6.7).

Find f (-12) if f (x) = -12x + 100
f(-12) = -12(-12) + 100 = 144 + 100 = 244
Answer:
244
Step-by-step explanation:
Substitute -12 as x.
f (-12) = -12(-12) + 100
f (-12) = 144 + 100

y=−2x+4 missing value ( - , -2)
30 points
Answer: Y=4
Step-by-step explanation:
Answer:
The missing value is 3.
Step-by-step explanation:
I plugged in -2 as y.
-2 = -2x+4
-2 -4 = -2x -4
-6 = -2x
-6/-2 = -2x/-2
3 = x
So the point is (3, -2)

Answer:
∠p= 15° , ∠q = 108° , ∠r = 57° Is the Answer
Step-by-step explanation:
, (x -12)° + (5x-27)° + (2x + 3)° = 180°
or, 8x° -36° = 180°
Or x =
So, x = 27°
∴ ∠P = 27° -12° = 15°
∠q = (5 × 27)° -27° = 108°
∠r = (2 × 27)° + 3° = 57°
