Answer:
0.84
Step-by-step explanation:
4x2+13a+10=7
13a=7-10-8
13a=-11
a=-11:13
a=0.84
Answer:
Step-by-step explanation:
angles in triangle = 180
1. 180 - (70+45) = x = 65
2. x = 35
180 - 110 = 70
70/2 = 35 (isosceles triangle)
3. x = 113, y = 67
180 - (62 + 51) = y = 67
Angles on a line = 180
180 - 67 = x = 113
4. x = 60, y = 50
x = 180 - 120 = 60
y = 180 - (60 + 70) = 50
answers in degrees.
Answer:
option A
Step-by-step explanation:
given coordinate (3, -6) and (–7, –4)
to find the equation of line
slope of the line passing through both the point will be



equation of line
( y - y₁ ) = m ( x - x₁ )

x + 5 y = -27
line which will not intersect will be parallel to it so option A has same slope as our line equation i.e. -1/5
hence, correct answer is option A
<u>Answer:</u>
The interest after 3 years is $360
<u>Explanation:</u>
Given the principal amount (P) = $3000
Rate of interest (R) = 0.04
Time period (T) is given as 3 years
The Simple Interest is calculated by the formula;

Substituting the values in the above formula,

SI = $360
Therefore, the interest after 3 years is $360
