Answer:

Step-by-step explanation:

h(x) = x² - 5x

x² - 5x = 104

x² - 5x - 104 = 0

D = (- 5)² - 4(1)(- 104) = 441 = 21²

$x_{1}$ = (5 - 21) / 2 = - 8

$x_{2}$ = (5 + 21) / 2 = 13

T-1 4/9+4 5/9=3 2/9. What is t equal to? I NEED HELPPPP

Shtirlitz [24]

Answer:

Step-by-step explanation:

As given t-1 4/9+4 5/9=3 2/9

t-13/9+41/9=29/9

t=29/9-41/9+13/9

now taking L.C.M

t=(29+13-41)/9

t=(42-41)/9

t=1/9

Pls answer if it is correct i will give brainlist

katrin2010 [14]

Answer:

1/ x = 22.5°

2/ x = 60°

Step-by-step explanation:

1/ We have: 3x + 2x + 3x = 180°

=> 8x = 180° => x = 22.5°

2/ We have: x + x + x = 3x = 180°

=> x = 60°

On a coordinate plane, a line has points (negative 2, negative 4) and (4, 2). Point P is at (0, 4). Which points lie on the line

NikAS [45]

Answer:

the correct options are:

(–1, 3), (–2, 2) and (–5, –1)

Step-by-step explanation:

Given that a line passes through two points

A(-2, -4) and B(4, 2)

Another point P(0, 4)

To find:

Which points lie on the line that passes through P and is parallel to line AB ?

Solution:

First of all, let us the find the equation of the line which is parallel to AB and passes through point P.

Parallel lines have the same slope.

Slope of a line is given as:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{2-(-4)}{4-(-2)} = 1$

Now, using slope intercept form ( $y = mx+c$ ) of a line, we can write the equation of line parallel to AB:

$y =(1)x+c \Rightarrow y = x+c$

Now, putting the point P(0,4) to find c:

$4 = 0 +c \Rightarrow c = 4$

So, the equation is $\bold{y=x+4}$

So, the coordinates given in the options which have value of y coordinate equal to 4 greater than x coordinate will be true.

So, the correct options are:

(–1, 3), (–2, 2) and (–5, –1)
