Answer:
x = 10y = 38Step-by-step explanation:
In order to solve for x and y, we must assume the figure is a parallelogram. In a parallelogram, opposite angles are congruent.
100 = 11x -10
110 = 11x
10 = x
__
80 = 2y +4
40 = y +2 . . . . divide by 2
38 = y

2. A parabola with x-intercept at 0 and 1 and at which passes through the point (2, -2).
Answers
Problem 1
Answer: y = 2x^2-4x-6--------------------------------
Explanation:
The x intercepts are -1 and 3, meaning that (x+1) and (x-3) are factors.
This is because x = -1 leads to x+1 = 0 when you add 1 to both sides. And x = 3 leads to x-3 = 0 when you subtract 3 from both sides.
The quadratic equation would be y = a(x+1)(x-3) = a(x^2-2x-3) for some constant 'a'. Use the point (x,y) = (1,-8) to find the value of 'a'.
y = a(x^2-2x-3)
-8 = a(1^2-2*1-3)
-8 = a(-4)
-4a = -8
a = -8/(-4)
a = 2
Therefore,
y = a(x^2-2x-3)
y = 2(x^2-2x-3)
y = 2x^2-4x-6
======================================================
Problem 2
Answer: y = -x^2+x--------------------------------
Explanation:
We'll follow the same idea as the previous problem.
The factors are (x-0) and (x-1). This is the same as saying the factors are x and (x-1)
So we have y = ax(x-1) = a(x^2-x)
Plug in (x,y) = (2,-2) and solve for 'a'.
y = a(x^2-x)
-2 = a(2^2-2)
-2 = a(2)
2a = -2
a = -2/2
a = -1
The equation updates to
y = a(x^2-x)
y = -1(x^2-x)
y = -x^2+x
Answer: 1) y = 2(x + 1)(x - 3)
2) y = -(x)(x - 1)
Step-by-step explanation:
Use the Intercept form of a quadratic equation: y = a(x - p)(x - q) where
p and q are the x-intercepts (aka zeros)"a" is the vertical stretch(x, y) is another point on the line --> use to find the a-value1) p = -1, q = 3, (x, y) = (1, -8)
y = a(x + 1)(x - 3)
-8 = a(1 + 1)(1 - 3)
-8 = a(2)(-2)
-8 = -4a
2 = a
Equation: y = 2(x + 1)(x - 3)
2) p = 0, q = 1, (x, y) = (2, -2)
y = a(x - 0)(x - 1)
-2 = a(2 - 0)(2 - 1)
-2 = a(2)(1)
-2 = 2a
-1 = a
Equation: y = -(x)(x - 1)

Diego wrote f(x)=(x+2)(x−4) as an example of a function whose graph has x-intercepts at x=−4, 2. What was his mistake?
Answers
x= -2 and x=4
His mistake was that he didn’t solve for x. To solve for x:
x+2=0
x=-2
and
x-4=0
x=4
Taking into account the factored form, Diego's mistake was to express the opposite signs to those he should have.
The function f(x) = ax² + bx + c
with a, b, c real numbers and a ≠ 0, is a function quadratic expressed in its polynomial form (It is so called because the function is expressed by a polynomial).
The following expression is called discriminant:
Δ= b²- 4*a*c
The discriminant determines the amount of roots of the function. The roots are those values of x for which the expression is 0, so it graphically cuts the x-axis.
Then:
If Δ <0 the function has no real roots and its graph does not intersect the x-axis. If Δ> 0 the function has two real roots and its graph intersects the x-axis at two points .If Δ = 0 the function has a real root and its graph intersects the x-axis at a single point that coincides with its vertex. In this case the function is said to have a double root.Every quadratic function can be factored based on its roots as:
f(x)= a(x-x1)(x-x2)
where x1 and x2 are the roots of the function. This way of expressing the quadratic function is called the factored form.
If the function does not have real roots (Δ <0) it cannot be factored, that is, it does not have a factored form.
If the function has a double real root (Δ = 0) the factored function takes the form:
f(x)= a(x-x1)²
In this case, the function has x-intercepts at x=−4, 2. So, an example of the factored form is:
f(x)=[x-(+2)][x-(-4)]
f(x)=(x-2)(x+4)
Finally, Diego's mistake was to express the opposite signs to those he should have.

3. A car and a truck were travelling in the same direction along the same road. The
car was travelling at a constant speed of 70 km/h and the truck was travelling at
a constant speed of 58 km/h. At 08:00, the truck was 20 km ahead of the car. Half
hour later, the truck broke down.
a) How far was the truck from the car when it broke down?
b) What time did the car pass the truck?
Answers
Take 8:00 to be the starting time, t = 0, and the car's starting position 20 km behind the truck to be the origin. Then the car's position at time t is
x = (70 km/h) t
and the truck's position is
x = 20 km + (58 km/h) t
(a) Right before the truck breaks down 0.5 h later, it will cover an additional distance of
(58 km/h) * (0.5 h) = 29 km
from its starting point, while the car will have covered a distance of
(70 km/h) * (0.5 h) = 35 km
from its starting point. So at 8:30, the truck is (20 km + 29 km) - 35 km = 14 km away from the car when it broke down.
(b) If neither vehicles stops, then the car passes the truck when their positions are equal, which would happen after
(70 km/h) t = 20 km + (58 km/h) t
(12 km/h) t = 20 km
t = (20 km) / (12 km/h)
t ≈ 1.7 h
But with the truck breaking down a 8:30, it is stuck 49 km away from the origin, so we need to find when the car travels this distance:
(70 km/h) t = 49 km
t = (49 km) / (70 km/h)
t = 0.7 h = 42 min
or at 8:42.

Answer:

Step-by-step explanation:
We know that the sum of the angles of a triangle is 180
HCA + CAH + AHB = 180
80+ CAH + 90 = 180
Combine like terms
170 + HAC = 180
HAC= 180-170
HAC = 10
We also know that HCA + ACB is a straight line so it adds to 180
HCA + ACB = 180
80+ACB = 180
ACB = 180-80
ACB = 100
Since ACB is isosceles the base angles have the same measure so CAB = ABC
We know that the sum of the angles of a triangle is 180
CAB + ABC + ACB = 180
Replacing ABC with CAB
CAB + CAB + 100 = 180
2CAB + 100 =180
2 CAB = 180-100
2 CAB = 80
Divide by 2
CAB = 80/2
CAB = 40
Now find HAB
HAB = HAC + CAB
= 10 + 40
= 50
To find: HAB=?
In Triangle HAC,
AHC=90 (given)
HCA=80 (given)
HCA+AHC+HAC=180 (ASP of a Triangle)
= 80+90+HAC=180
AHC=10
Now,
HCA+ACB=180 (Linear Pair)
= 80+ACB=180
ACB=100
In Triangle ACB,
CAB=CBA (given)
So let them both be x
= x+x+ACB=180 (ASP of triangles)
= 2x=180-100
= x=80/2
x= 40
Therefore, CAB=CBA=40
HAB=AHC+CAB
= 10+40
Thus, Angle HAB=50 degrees
