Answer:
x=0
Step-by-step explanation:
Let 5x = y.
(52)x+3(5x)−4=0
y2+3y−4=0
y2−y+4y−4=0
y(y−1)+4(y−1)=0
(y+4)(y−1)=0
y=−4;y=1
y = -4 is not possible.
y = 1 ⟹ x = 0.
4(x+3)+x=0
4x+12+x=0
5x+12=0
5x=-12
x=-2.4
the first number -2.4
the second number 1.4
the third number 5.6
Answer:
The slope is -3/4
Step-by-step explanation:
To find slope:
y1 - y2 / x1 - x2
(2,5) and (-2,8)
8 - 5 / -2 - 2
3/-4
Step-by-step explanation:
a) sample space = 10
I.e the total number of possible outcomes
b) A = {7,8,9,10 }
B = {4,9
c) A U B = {4,7,8,9,10}
d) pr (A) = no of events in A÷ total sample space
pr (A) = 4/10
=2/10
e) pr( A U B) = 5/ 10
= ½
$864 all you had to do was multiply 216 by 4 and 380 by 4 to get 1520 and 656 subtract that to get 864
