Answer: x = 3/4 x = -5
Step-by-step explanation:
x+5=0
x=-5
4x-3=0
Add three to both sides
4x = 3
x=3/4
Answer:
7%
Step-by-step explanation:
Using the formula
Amount = Principal + Interest
Give the following
Principal = ₹ 5000
Amount =₹ 6050
Time = 3 years
Required
Time
Substitute into the formula
A = P + I
A = P + PRT/100
6050 = 5000 + 5000(R)(3)/100
6050 - 5000 = 150R
1050 = 150R
R = 1050/150
R = 7
Hence the rate of interest is 7%
Answer:
x = 4, -10
Step-by-step explanation:
Find the zeros of the equations.
Solve the equation:
x^2 + 6x = 40
Subtract -40 from both sides.
x^2 + 6x - 40 = 0
Factor the equation.
(x - 4)(x + 10)
Solve for x with the given information by equaling it to 0.
x - 4 = 0
Add 4 to both sides
x = 4
x + 10 = 0
Subtract 10 from both sides
x = -10
This means that our x values are:
x = 4, -10
Answer:
y = 6x+9
Step-by-step explanation:
Equations that are parallel have the same slope
y = 6x+7 is written in slope intercept form where the slope is 6 and the y intercept is 7
The lines will have a slope of 6
The point (0,9) is the y intercept because the x value is 0
We can write the equation in slope intercept form y = mx+b
y = 6x+9
Its is surprising that no one attempted this question for over a week.
As in all geometry problems, start with a diagram (shown).
Then we realize right away that AB=sqrt(8^2+2^2)=sqrt(68)=2sqrt(17)
BC=sqrt(4^2+1^2)=sqrt(17)
The perimeter is therefore twice the sum of AB+BC=2(2sqrt(17)+sqrt(17))
2(3sqrt(17))=6 sqrt(17) We can estimate sqrt(17)=4.125, so 6sqrt(17)=24.75 which is close enough to get the correct answer choice.
Have a good day.
