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

Which of the following statements justifies why the triangle shown below is
not a right triangle?
A. BC + AC > AB
B. AC< AB
C. BC < AB
D. 5^2+10^2 ≠ 12^2
Answers
because it does not abide by the pythagorean theorem
a^2 + b^2 = c^2
in this case:
5^2+10^2 ≠ 12^2
25+100≠144
125≠144
Therefore D shows that the triangle isn’t a right angle triangle.
The statement that justifies why the triangle shown below is not a right-angle triangle is [tex](5)^{2} + (10)^{2}[/tex] ≠ [tex](12)^{2}[/tex]
What is a right-angle triangle?A right-angle triangle is a triangle that has a right-angle.
Here, the sides of the triangle are 5, 10, and 12.
As per Pythagorean theorem for a right-angle triangle,
(Base)² + (Height)² = (Hypotenuse)²
Now, for the given triangle:
[tex](5)^{2} + (10)^{2}[/tex]
[tex]= 25 + 100\\= 125\\= 11.18[/tex]
≠ [tex](12)^{2}[/tex]
Therefore, the given triangle is not a right-angle triangle.

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)

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
