Answer:
Step-by-step explanation:
2x + 4 = 2(x + 2)
[tex]Area = \frac{1}{2}*b*h\\\\=\frac{1}{2}*(2x-1)(2x + 4)\\\\\\= \frac{1}{2}*(2x - 1)*2*(x + 2)\\\\= (2x -1)(x+ 2)[/tex]
= 2x *x + 2x* 2 + x*(-1) + 2*(-1)
= 2x² + 4x - x - 2
= 2x² + 3x - 2

3. Find the measure of the sides of the triangle if the vertices of AEFG are E
(1,4), F(5, 4), and G(1,0). Then classify the triangle by its sides.
Answers
The triangle EFG is an isosceles triangle as side EF is congruent to side EG.
How to determine a triangle according to its sides
In this question we have a triangle whose vertices are known. We need to define the figure according to the congruency among its sides. Two sides are congruent when both have the same length. There are three kinds of triangles:
Scalene - Three sides of different length.Isosceles - Two sides of equal length.Equilateral - All sides are of equal length.Sides are formed each pair of vertices. The length of each side can be found by means of Pythagorean theorem:
l = √[(Δx)² + (Δy)²]
First, write the locations of the vertices:
E(x, y) = (1, 4), F(x, y) = (5, 4), G(x, y) = (1, 0)
Second, determine the length of every side of the triangle:
EF = √[(5 - 1)² + (4 - 4)²]
EF = 4
FG = √[(1 - 5)² + (0 - 4)²]
FG = √[4² + (- 4)²]
FG = 4√2
EG = √[(1 - 1)² + (0 - 4)²]
EG = 4
By direct comparison, we conclude that the triangle EFG is an isosceles triangle.

A golfer hit a golf ball from a tee box that is 6 yards above the ground. The graph shows the height in yards of the golf ball above the ground as a quadratic function of x, the horizontal distance in yards of the golf ball from the tee box. What is the domain of the function for this situation?
Answers
Answer: C. 0 ≤ x ≤ 230
When the A golfer hit a golf ball from a tee box that is 6 yards above the ground so the domain of the function is [0,260].
Calculation of the domain of the equation:Here the domain is the values of 'x' in the function f(x).
the position at which the golfer is hit the ball is (0,6) and the position where the ball hits the ground is (230,0)
So, the domain of the function for this situation is [0,260].

5) If Oskar bisects the diameter of a circle, what is he trying to construct?
6) What is the center and radius of a circle with the equation (x - 5)+ (y + 3)2 = 49
Answers
Answer:
Center = (5,-3) and radius = 7
Step-by-step explanation:
(5) If Oskar bisects the diameter of a circle, what is he trying to construct the radius of the circle.
(6) The given equation is :
[tex](x-5)^2+(y+3)^2=49[/tex]
The general equation of circle is given by :
[tex](x-a)^2+(y-b)^2=r^2[/tex] ...(1)
Where
(a,b) are the coordinates of the centre and r is the radius.
The given equation can be written as :
[tex](x-5)^2+(y+3)^2=7^2[/tex] ..(2)
Comparing equation (1) and (2) we get :
a = 5, b = -3 and r = 7
So,
Center = (5,-3) and radius = 7
Hence, this is the required solution.
At your first job you make $1200 a month of that you save $200 a month. Your goal is to save 20% did you reach your goal?
Answers
Answer:
No, you didn't
Step-by-step explanation:
20% of $1200 is:
0.2*$1200 = $240Since you saved $200 and its less than $240 you didn't reach your goal
Hi there!
No:
200 is only 6 parts of 1200 together which means that it can’t be 20% of 1200.
If it was 20% of 1200, it would then be 240 since 240·5=1200...
What this means:
No, did not reach the goal since 20% of 1,200 is 240 and 200 is only 16.67% of $1,200.

Answer:
6. x = 15
7. JL = 78
Step-by-step explanation:
6. 8x - 23 = ½(10x + 44) (midsegment theorem)
Multiply both sides by 2
2(8x - 23) = 10x + 44
16x - 46 = 10x + 44
Collect like terms
16x - 10x = 46 + 44
6x = 90
Divide both sides by 6
x = 90/6
x = 15
7. MN = 5x - 16
JL = 4x + 34
MN = ½(JL) (midsegment theorem)
5x - 16 = ½(4x + 34) (substitution)
2(5x - 16) = 4x + 34
10x - 32 = 4x + 34
Collect like terms
10x - 4x = 32 + 34
6x = 66
x = 66/6
x = 11
JL = 4x + 34
Plug in the value of x
JL = 4(11) + 34 = 44 + 34
JL = 78
