Answer: Im pretty sure its x = 4.472135955

Step-by-step explanation:

DISCLAIMER: I may be wrong I am kind of rusty.

You got to use the Pythagorean theorem (a^2 + b^2 = c^2) to answer this.

First you label your triangle by putting the hypotenuse as "c" the other known value as "b" and the unknown value as "a".

Now you input the answers into the equation.

x^2 + 4^2 = 6^2

Now answer the known values.

x^2 + 16 = 36

Now subtract by 16 to get rid of the sixteen.

x^2 + 16 -16 = 36 -16

x^2 = 20

Now to get rid off the ^2 find the square root.

x = 4.472135955

Answer:

-8 <_ x < -3

-7 <_ y < -2

Step-by-step explanation:

closed dot means it includes that number so in this case x is least than or equal to -8 and open dot means it doesn't include that value so x is less than -3 and does NOT include -3

and for the y value it's pretty self explanatory if u just count it (i might be off by a little cuz the photo quality is kinda fuzzy but i hope u get the gist!)

write the standard form of the equation of the line described. through (-2,3), perpendicular to y=2/7x+5

Setler79 [48]

The general form of a linear equation is
y = mx + b
where m = slope and b = y-intercept
Here m = 2/7
To get to its perpendicular equation, first the slope should be negative reciprocal. So the perpendicular slope is m = -7/2
Given the point (-2,3), use the point-slope form equation, that is
y - y1 = m(x - x1)
Plug in
y - 3 = (-7/2)[x - (-2)]
y - 3 = (-7/2)x - 7
y = (-7/2)x - 7 + 3
y = (-7/2)x - 4
That is the equation required.

Sarah used 2.5 cups of cheese in a dish that serves 10 people. Amyn used 1.6 cups of cheese in a dish that serves 8 people.

Drupady [299]

Is D
Explanation : you have to divide the amounts too see how many cheese for one person and then you subtract them and you get you answer that will be like this
2.5 divided by 10 = 0.25
1.6 divided by 8 = 0.2
0.25 - 0.2 = 0.05

4. What kind of triangle is made by connecting the points A(0, –6), B(3, –6), and C(3, –2)?

Firdavs [7]

Answer:

Part 4) Right triangle

Part 5) Kite

Step-by-step explanation:

Part 4) What kind of triangle is made by connecting the points A(0, –6), B(3, –6), and C(3, –2)?

Using a graphing tool

see the attached figure N $1$

The triangle of the figure is not equilateral------> The triangle does not have three equal sides

The triangle of the figure is a right triangle------>The triangle has an angle of $90\°$

The triangle of the figure is not isosceles------> The triangle does not have two equal sides

The triangle of the figure is not a right and isosceles

Part 5) What type of quadrilateral is formed by connecting the points $(0, 9), (3, 6), (0, 1), and (-3, 6)$ ?

Using a graphing tool

see the attached figure N $2$

The figure is not a rhombus------> All sides are not congruent

The figure is not a trapezoid-----> has not parallel sides

The figure is a kite------> Two disjoint pairs of consecutive sides are congruent and the diagonals meet at a right angle
