Answers
Answer:
(4, -6)Step-by-step explanation:
The formula of a midpoint of the segment AB:
[tex]M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)[/tex]
We have A(7, -2) and B(1, -10). Substitute:
[tex]M_{AB}\left(\dfrac{7+1}{2};\ \dfrac{-2+(-10)}{2}\right)\\\\M_{AB}\left(\dfrac{8}{2};\ \dfrac{-12}{2}\right)\\\\M_{AB}(4;\ -6)[/tex]
(7+1)/2 x value = 4
(-2+ -10)/2 y value = -6

What is the image of (-9,6) after a dilation by a scale factor of 44 centered at the origin?
Answers
Answer:
(- 396, 264 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply each of the coordinates of the point by the scale factor, that is
(- 9, 6 ) → ( (- 9 × 44 ), (6 × 44 ) ) = ( - 396, 264 )

Draw triangle ABC by first drawing segment BC six inches long. Then draw a 60° angle at vertex B and a 60° angle at vertex C. Extend the segments so that they intersect at point A.
Answers
Answer:
Step-by-step explanation:
Given that segment BC is the base of the triangle, this drawing shows that triangle ABC is an equilateral triangle.
Since;
<B = <C = 60°
Then,
<A + <B + <C = [tex]180^{o}[/tex]
<A + 60° + 60° = [tex]180^{o}[/tex]
<A = [tex]180^{o}[/tex] - [tex]120^{o}[/tex]
= 60°
Thus,
AB = BC = AC = 6 inches

Combine like terms which are 5 and -2
Answer:
3 + 2b
Step-by-step explanation:
To simplify, you have to combine (add) like terms. The like terms are 5 and -2 because they both do not have a variable.
5 + (-2) = 3
2b stays the same because there are no like terms for it.

What is the general equation of a Straight line?
The general equation of a straight line is -
y = mx + c
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have line [m] passes through points (10, 10) and (2, 1).
We can write the equation of line [m] as follows.
slope of line [m] = a = (1 - 10)/(2 - 10) = -9/-8 = 9/8
a = 9/8
slope of line [n] -
m[n] x a = - 1
m[n] = -1/a
m[n] = -8/9
Therefore, the slope of line [n] would be -8/9.

Determine the mass of an object, if it requires a force of 6,000 kg: m/s2 to accelerate at the rate of 2 m/s^2
Answers
Answer:
The answer is 3000 kgStep-by-step explanation:
The mass of an object can be found by using the formula
[tex]m = \frac{f}{a} \\ [/tex]
f is the force
a is the acceleration
From the question we have
[tex]m = \frac{6000}{2} \\ [/tex]
We have the final answer as
3000 kgHope this helps you
[tex] \boxed{ \red{AnswEr:-}}[/tex]
Mass = 3000 kg★ GivEn :-
Force = 6000 kg • m/s^2Acceleration = 2 m/s^2★ To Find :-
The value of mass★ Solution :-
From Newton's 2nd law of motion we get the equation,
[tex]{ \boxed{ \red{ \sf{F =
m \times a}}}}[/tex]
where,
F = Force m = mass of the objecta = acceleration[tex] \implies \sf \: m = \dfrac{F}{a} [/tex]
Putting the values,
[tex] \implies \sf \: m = \dfrac{6000}{2} [/tex]
[tex] \implies \red{\sf \: m = 3000}[/tex]
Therefore, mass of the object = 3000 kg
Adam, Bethany and Charles played a game.

They scored a total of 72 points.
Find the number of points that Adam, Bethany and Charles each scored.
Answers
Points scored by Adam, Bethany and Charles are 25, 17 and 30 respectively.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
Given that,
Adam scored 8 more points than Charles,
And Bethany scored 5 more points than Adam.
Also, total score is 72.
Let points scored by Adam is x,
Then point scored by Charles = x-8,
And point scored by Bethany = x+5.
Since, total score = 72
x + x-8 + x+5 = 72
3x - 3 = 72
3x = 75
x = 25
Points scored by Adam is x = 25,
Point scored by Charles = x-8 = 17,
And point scored by Bethany = x+5 = 30.
