Answer:

x = 0

Step-by-step explanation:

if you enter -5(0)^2+6(0), you get 0

if you enter -5(1)^2+6(1), you get 1

if you enter -5(-1)^2+6(-1), you get -11

Answer:

65, 72, 97

Step-by-step explanation:

Here,

According to figure,

longest side is 97. So it the length of hypoteneous(h) and the shortest side is 65 so it is the length of perpendicular(p) and last one, 72 is the lenght of base(b) of triangle.

According to Pythagorus theorem,

${h}^{2} = {p}^{2} + {b}^{2} \\ or \: {97}^{2} = {65}^{2} + {72}^{2} \\ or \: 9409 = 4225 + 5184 \\ or \: 9409 = 9409$

which is true.

If you test the same theorem in other options.The reasult will unsatisfied.

how do you write a linear equation when given a graph or table? and how do you analyze key features of a function when given its

Agata [3.3K]

When given a graph or table, you first want to figure out the slope. Look at the graph or table, and see how much does y change when x change in a certain amount? You want it as a rise/run so if x increases 2 when y increases 3 then the slope would be 3/2.

Next, you want to find the y intercept.
Look at the y value when x is 0. If the y is -2 when x=0, then b=-2.

When given its graph, find a y value when x is 0. If the y is 4 when x=0 then b=4

What must the measure of angle LMN be? m∠LMN = °

luda_lava [24]

Both 25x and 22x + 9 have the same answers. So you set those two equal to each other.
$25x = 22x + 9$
Subtract 22x from both sides.
$3x = 9$
and you're left with this.
Next, divide 3 from both sides.
$x = 3$
re-insert 3 into one of the equations.
$25(3) = 75$
add up both angles
$75 + 75 = 150$
all angles (for quadrilaterals)added up equals 360.
$150 + 2x = 360$
solve for x. Subtract 150 from both sides.
$2x = 210$
and divide 2 from both sides
$x = 105$
AngleLMN= 105
