    -t(5t - 7) = -5
          -1         -1
     t(5t - 7) = 5
  t(5t) - t(7) = 5
     5t² - 7t = 5
5t² - 7t - 5 = 0
t = -(-7) ± √(-7)² - 4(5)(-5)
                 2(5)
t = 7 ± √49 - 4(-25)
               10
t = 7 ± √49 + 100
             10
t = 7 ± √149
         10
t = 0.7 ± 0.1√149

(a)

A right angle sums to 90 

6x + 4x + 10 = 90

10 x = 80

x = 8

(b) straight line = 180

5x + 13  + 3x + 7 = 180

x = 20

(c)  Sum of triangle angles = 180

3x + 5  + 2x + 18 + 2x + 17 = 180

x = 20

(d) Sum of two angles in right angle = 90

90 = x + 30

x = 60

Complete the equation of the line through (-10,-7)(−10,−7)(, minus, 10, comma, minus, 7, )and (-5,-9)(−5,−9)(, minus, 5, comma,
Tanzania [10]

Answer:

y = -\frac{2}{5}\cdot x - 11

Step-by-step explanation:

First, the slope is determined by using the following expression:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m = \frac{-7-(-9)}{-10 - (-5)}

m = -\frac{2}{5}

The y-intercept is found by using the line equation, the slope and one point:

y = m \cdot x +b

b = y - m\cdot x

b = -7 - \left(-\frac{2}{5}\right)\cdot (-10)

b = -11

The equation of the line is:

y = -\frac{2}{5}\cdot x - 11
