Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)
m = [tex]\frac{6+3}{2-8}[/tex] = [tex]\frac{9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]
------------------------------------------
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y = 5 - 2x , that is
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2

Assume that y varies directly with x, then solve.
if y=-6.6 when x=9.9, find y when x=6.6
Answers
Answer:
y = - 4.4
Step-by-step explanation:
Given that t varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6.6 when x = 9.9 , that is
- 6.6 = 9.9k ( divide both sides by 9.9 )
k = [tex]\frac{-6.6}{9.9}[/tex] = - [tex]\frac{2}{3}[/tex]
y = - [tex]\frac{2}{3}[/tex] k ← equation of variation
When x = 6.6, then
y = - [tex]\frac{2}{3}[/tex] × 6.6 = - 2 × 2.2 = - 4.4

Answer:
2) x=6 3) x=4 m<EFH=21 m<EFG=83
Step-by-step explanation:
2) Basically they're giving you two parts of a whole angle. The entire angle is 127 degrees, split into two parts. one part being 83 degrees and the other is (9x-10). the way you solve for X is by making it into an equation. Angle JKM + angle MKL = angle JKL. So substitute the values they gave you into the one we just made.
(9x-10) + 83 = 127 then solve for x.
9x-10+83=127
9x+73=127
9x=54
x=6
3) this question is the same thing but now theres a variable on both sides of the equation. angle EFH +angle HFG = angle EGF. substitute then solve for x
(5x+1) + 62 = 18x+11
5x+63=18x+11 move the x variables to one side
52=13x
x=4
for the rest of the angles just plug in the x value to the equations for the smaller angles
m<EGF:
18x+11
18(4)+11= 83
m<EFH
5x+1
5(4)+1= 21

Subtract 8 from both sides:
[tex]3x+8-8=4x+6-8[/tex]
[tex]3x=4x-2[/tex]
Subtract 4x from both sides:

[tex]-x=-2[/tex]
Divide both sides by -1:

Locate the vertex and the axis of symmetry of the quadratic graph y = 7 * (x - 4) ^ 2 - 5 . Determine the range.
Answers
Answer:
The vertex is (4,-5) and the axis of symmetry is x = 4. The range is all real numbers
Step-by-step explanation:
vertex is calculated by -b/2a so the vertex would be -5/2(2) which is equal to (4,-5).
The axis of symmetry is the x number in the vertex so it would be x = 4.
Answer:
vertex is (4, -5)
Step-by-step explanation:
given:
y = 7 * (x - 4) ^ 2 - 5
find:
Determine the range.
y = 7 * (x - 4) ^ 2 - 5
rewrite in the form of y = ax² + bx + c
y = 7x² - 56x + 107
the parameters are:
a = 7
b = -56
c = 107
Xv = - ( - 56 )
2 * 7
simplify:
Xv = 4
plugin values into Yv
Yv = -5
therefore the vertex is (4, -5)

Answers
Answer:
x > 1.5
Step-by-step explanation:
In order to solve for x, we must isolate x on one side of the inequality.
[tex]4.2x > 6.3[/tex]
x is being multiplied by 4.2 The inverse of multiplication is division. Divide both sides of the equation by 4.2
[tex]\frac{4.2x}{4.2} >\frac{6.3}{4.2}[/tex]
[tex]x> \frac{6.3}{4.2}[/tex]
