Answer:
x = 2 , 9
Step-by-step explanation:
[tex] {x}^{2} - 11x + 18 = 0[/tex]
[tex] = > {x}^{2} - 9x - 2x + 18 = 0[/tex]
[tex] = > x(x - 9) - 2(x - 9) = 0[/tex]
[tex] = > (x - 9)(x - 2) = 0[/tex]
Here x will have 2 solutions.
1) [tex]x - 9 = 0[/tex]
[tex] = > x = 9[/tex]
2)[tex]x - 2 = 0[/tex]
[tex] = > x = 2[/tex]
Hence the 2 solutions of x are +2 & +9

Point-slope form
Complete the point-slope equation of the line through (8, —8) and (9.8).
Use exact numbers.
y-8=
Answer:
The equation in point-slope form is:
[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]
The equation of the line in slope-intercept form is:
[tex]y=16x-136[/tex]
Step-by-step explanation:
Given the points
(8, -8)
(9, 8)
Finding the slope between (8, -8) and (9, 8)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(8,\:-8\right),\:\left(x_2,\:y_2\right)=\left(9,\:8\right)[/tex]
[tex]m=\frac{8-\left(-8\right)}{9-8}[/tex]
[tex]m=16[/tex]
Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Here:
m is the slope and (x₁, y₁) is the point
substituting the values m = 16 and the point (8, -8) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]
Thus, the equation in point-slope form is:[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]
now completing the point-slope form equation of the line
[tex]y+8=16\left(x-8\right)[/tex]
subtract 8 from both sides
[tex]y+8-8=16\left(x-8\right)-8[/tex]
[tex]y=16x-136[/tex]
Thus, the equation of the line in slope-intercept form is:[tex]y=16x-136[/tex]

Solve the system of equations by substitution.
3x+y = 10
7x+ 2y= 24
A. (2,4)
B. (2,-6)
C. (4,-2)
D. (2,-4)
If you can, explain step by step please :)
Answer:
C
Step-by-step explanation:
3x+y=10---(1)
7x+2y=24---(2)
From(1)
3x+y=10
y=10-3x---(3)
Substitute(3)into(2)
7x+2y=24
7x+2(10-3x)=24
7x+20-6x=24
x+20=24
x=24-20
x=4
Substitute x=4 into (1)
3x+y=10
3(4)+y=10
12+y=10
y=10-12
y=-2

Select the slope and y-intercept of the relationship shown in the table
Answer:
slope = 0.05, y-intercept = 2,000Hence, option A is true.
Step-by-step explanation:
x y
10, 000 2,500
20, 000 3,000
30, 000 3, 500
Taking two points (10000, 2500) and (20000, 3000) to find the slope between the points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{3000-2500}{20000-10000}[/tex]
[tex]m=\frac{1}{20}[/tex]
[tex]m=0.05[/tex]
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where 'm' is the slope and 'b' is the y-intercept
substituting the point (10000, 2500) and m=0.05 in the slope-intercept form
[tex]y=mx+b[/tex]
[tex]2500\:=\:0.05\left(10000\right)+b[/tex]
[tex]500+b=2500[/tex]
[tex]b=2000[/tex]
Thus, the y-intercept is: b=2000
Thus,
slope = 0.05, y-intercept = 2,000Hence, option A is true.

How many different triangles ABC can be formed if C=60∘, c=17√3 and a=34?
Answer:
Jordan, Its been 5 hours, whats the answer?
Step-by-step explanation:
There can be only 1 triangle formed by the given information.
What is triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.
Given that, ABC can be formed if C=60∘, c=17√3 and a=34
Using the sine law for triangle,
A/sina = B/sinb = C/sinc
34/sina = 17√3/sin60°
⇒ sina = 90°
Since, The triangle ABC is a right triangle,
Hence, There can be only 1 triangle formed by the given information.

What was the value of b?
A. –6
B. –2
C. 2
D. 10
Answer: C. 2
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Begin by removing the brackets
4x + 5(-4x - b) = -16x - 5b
-(x - 2) = -x + 2
Add the two binomials together to get the third one
4x -20x - 5b - x + 2 = -17x - 8 Combine the like terms on both sides
-17x - 5b +2 = -17x - 8 Add 17x to both sides
-5b + 2 = - 8 Subtract 2 from both sides
-5b +2 -2 =- 8 -2 Combine
-5b = - 10 Divide by -5
b = -10/-5
b = 2
