What word best describe the line of symmetry in the letter D

1 answer:

The line of symmetry can never be symmetrical. If you put a vertical line through the middle the sides aren't equal. Same for horizontal and diagonal.

Look at the image below. 7 5 4 What is the area of the triangle?

Likurg_2 [28]

Step-by-step explanation:

the area of a triangle is always

baseline × height / 2

where baseline and height are perpendicular (with a 90° angle) to each other.

it does not matter, if the height is inside or outside of the triangle.

so, in our case the area is

4×5/2 = 2×5 = 10 units²

What is the vertex? y=2x^2+28x-8

ra1l [238]

Fist convert the equation to vertex form

y = 2(x^2 + 14x) - 8
y = 2 [(x + 7)^2 - 49] - 8
y = 2(x + 7)^2 - 106

So the vertex is at (-7,-106)

In a cross-country run organized by a school, the students who completed the run

coldgirl [10]

280 students have a total of 560 points

There 60 more boys(x+60) complete than girls(x)

2*(x+60)+2*x= 560

number of girl =x =110

girl point =110*2= 220

Mhanifa can you please help? I will mark brainliest!

Answer:

Given function

h(x) = 2x - 1

#15 Find the inverse of h(x)

Substitute x with y and h(x) with x and solve for y:

x = 2y - 1
2y = x + 1
y = 1/2x + 1/2

The inverse is:

h⁻¹(x) = 1/2x + 1/2

#16 The graph with both lines is attached.

The x- and y-intercepts of both functions have reversed values.

#17 Table of the inverse function will contain same numbers with swapped domain and range.

Initial look is like this:

x | -3 | -2 | -1 | 0 | 1 | 2 | 3
h⁻¹(x) | -1 | | 0 | | 1 | | 2

The rest of the table is filled in by finding the values:

x | -3 | -2 | -1 | 0 | 1 | 2 | 3
h⁻¹(x) | -1 | -0.5 | 0 | 0.5 | 1 | 1.5 | 2
