Explanation: Took the quiz
Solve the equation:
5x + 65 = 25
What is the value of x
Answer: -8
Step-by-step explanation:
Answer:
x = -8
Step-by-step explanation:
If you multiply -8 by 5 you get -40. Then if you add 65 to -40 you get 25.
Hope this helps.
B. 12 in.
C. square root 189 in.
D. square root 261 in
Answer: C. square root 189 in.
Step-by-step explanation:
Given : The length of the hypotenuse of a right triangle is 15 in.
The length of one leg = 6 in.
Let x be the length of other leg, then
According to Pythagoras theorem ,we have
Hypotenuse² = Perpendicular² + Base²
Hence, the length of the other leg is
Thus , the correct answer is C. square root 189 in.
Answer:
square root 189 i did the math and google says the same
Step-by-step explanation:
The lines 2x + ky = 3 and kx + 8y = 7 intersect for all values of k except 4 and -4 the answer is R - {4, -4}.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two linear equations in two variables are:
2x + ky = 3 and
kx + 8y = 7
As we know the condition for the lines to intersect or have unique solutions:
2/k ≠ k/8
After cross multiplication:
k² ≠ 16
k ≠ ±4
The values of k can be anything except 4 and - 4
Thus, the lines 2x + ky = 3 and kx + 8y = 7 intersect for all values of k except 4 and -4 the answer is R - {4, -4}.

Answer:
ky=3-2x
y=(3-2x)/k
y=(7-kx)/8
(3-2x)/k=(7-kx)/8
8(3-2x)=(7-kx)k
24-16x=7k-k*kx
24=7k-kkx+16x
24+7k=kkx+16x
24+7k=x(k^2+16)
