Which equation has both 7 and -7 as a
possible value of x?
A. X^2=14
B. x^3=14
C. X^3=49
D. X^2=49
Answer:
D. X^2=49
Step-by-step explanation:
X= -4 or X=7
X^2=(-7)^2=49
or
X^2=(7)^2=49
put the following equation of a line into a slope-intercept form, simplifying all fractions.
3y-3x=21
To find the slope-intercept form (y=mx+c), we have to make 'y' the subject of the equation:
3y - 3x = 21 [add 3x to both sides]
3y = 3x + 21 [divide all terms by 3]
y = x + 7
∴ 3y - 3x = 21 in slope-intercept form is y = x + 7.Points A and B have coordinates (8, 3) and (p, q) respectively. The equation of the perpendicular
bisector of AB is y = -2x +4.
Find the values of p and q.
Answer:
p = -4, q = -3
Step-by-step explanation:
y = -2x +4 ... (1) perpendicular bisector of AB, slope = -2
slope of AB = 1/2
Line AB pass (8,3): (y-3) / (x-8) = 1/2
AB equation: y-3 = 1/2(x-8) y = 1/2x - 1 ... (2)
(2)-(1): 5/2 x = 5 x = 2
y = 0 (2,0) intercept of bisector and AB, it is midpoint of A (8,3) and (p,q)
(8+p)/2 = 2
p = -4
(3+q)/2 = 0
q = -3
The values of p and q from the perpendicular bisector are;
p = -4 and q = -3
We are given coordinates of A and B as;
A(8, 3) and B(p, q)
Bisector of AB is y = -2x + 4
Thus, from y = mx + c, Slope of the bisector is -2.
Since the bisector is perpendicular to AB, then slope of AB = -(1/-2) = 1/2
Thus, slope of the line from point A to the point of the bisector on AB is;
(y - 3)/(x - 8) = 1/2
y - 3 = ¹/₂(x - 8)
y - 3 = ¹/₂x - 4
y = ¹/₂x - 1
Putting ¹/₂x - 1 for y in the bisector equation gives;
¹/₂x - 1 = -2x + 4
2x + ¹/₂x = 4 + 1
2.5x = 5
x = 5/2.5
x = 2
Thus;
y = -2(2) + 4
y = 0
Thus, the coordinate of the midpoint of AB is (2, 0)
Now, this means that;
(8 + p)/2 = 2
8 + p = 4
p = 4 - 8
p = 4
Also; (3 + q)/2 = 0
3 + q = 0
q = -3

Directions: Solve for x, then find each angle measure.
The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
Therefore, ∠E + ∠F + ∠D = 180°.
Given that, ∠E = 9x + 3,∠F = 11x -21 and ∠D = 5x - 2
So, 9x + 3 + 11x - 21 + 5x - 2 = 180
25x - 20 =180
25x = 200
x = 8
So,
∠E = 9(8) + 3 = 75°
∠F = 11(8) - 21 = 67°
∠D = 5(8) -2 = 38°
Hence "The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°".

Can you solve it please
Answer:
x = 10
Step-by-step explanation:
1. First, we should recognize that 6x and 5x + 10 are corresponding angles, meaning they occupy the same relative position. They're also congruent.
This means that 6x = 5x + 102. (Solving)
Step 1: Subtract 5x from both sides.
[tex]6x - 5x = 5x + 10 - 5x[/tex] [tex]x = 10[/tex]Step 2: Check if solution is correct.
[tex]6(10)=5(10)+10[/tex] [tex]60 = 50 + 10[/tex] [tex]60 = 60[/tex]Therefore, x = 10.
