Step-by-step explanation:
maybe this is not the full expression, as you wrote the line equation in a funny way.
I understand the following :
the line is
y = (-2/5)×x - 7
perpendicular means crossing at a right angle (90 degrees).
the slope of the original line is -2/5.
as in every line equation, the slope is the factor of x. and it expresses the ratio y/x indicating the amount of units y is changing, when x changes a certain amount of units (e.g. when going from one point on the line to another).
the perpendicular slope turns the original y/x ratio upside-down, and also flips the sign.
so, it is 5/2.
the equation for the perpendicular line looks like
y = (5/2)×x + b
now what is b ?
for this we use the specified point on the line : (4, -1)
and we put these values as x and y into the equation :
-1 = (5/2)×4 + b = 5×2 + b = 10 + b
b = -11
and so, the full equation of the perpendicular line is
y = (5/2)×x - 11

Use substitution to solve 2x2=5+y and 4y= -20+8x2
Solve the first equation for Y and substitute it into the second equation. The resulting equation is?
Step-by-step explanation:
First
2 × 2 = 5 + y
y = -1
And
4y = -20 + 8 × 2
4 × (-1) = -4
-4 = -4
Is this what you wanted?
Rationalize the denominator.
– 5x4
✓4x +7
The question is asking us to make the denominator a rational function by finding a way to remove the square root without changing the value of the overall function.
We can do this by multiplying the denominator and numerator by the √(4x + 7), since multiplying a root term by that root term = the number being rooted (√x × √x = x).
- 5x⁴ × √(4x + 7) = (-5x⁴)(√(4x + 7))
√(4x + 7) √(4x + 7) 4x + 7

Sachin used synthetic division to divide a polynomial, p(x), by x + 5 and found that there was no remainder. What does this tell Sachin about how p(x) and x + 5 are related?
A. x + 5 is a factor of p(x)
B. p(x) divided by x + 5 is 0
C. x + 5 is not a factor of p(x)
D. x + 5 cannot be divided evenly into p(x)
Answer:
A
Step-by-step explanation:
The x + 5 is a factor of p(x) this represents that p(x) and x + 5 are related.
Given that,
Let us assume polynomial be p(x), and it is divided by x + 5.There is no remainder.Based on the above information, we can say that
x + 5 represent the factor of p(x).
Therefore we can conclude that the first option is correct.

Answer:
Common ratio is - 4 / 2.
Step-by-step explanation:
Sequence = - 2, 4, - 8, 16, - 32, ....
Let the terms be " a ".
Here,
a1 = 2
a2 = 4
a3 = - 8
a4 = 16
a5 = - 32
Let the common ratio be " r ".
r1 = a2 / a1
= 4 / - 2
r1 = - 2
r2 = a3 / a2
= - 8 / 4
r2 = - 2
r3 = a4 / a3
= 16 / - 8
r3 = - 2
r4 = a5 / q4
= - 32 / 16
r4 = - 2
Since, the common ratios are same,
Therefore, r = - 2
- 4 / 2 = - 2
So, - 2 can also be written as - 4 / 2.
Hence,
r = - 4 / 2
Finally,
Common ratio ( r ) = - 4 / 2

Find the 11" term of the following geometric sequence.
5, 15, 45, 135, ...
If AM = x + 8 and MB= 6x – 2, find MB.
Answer:
10
Step-by-step explanation:
Firstly, AM=x+8
or, A=x+8-M......eqn (i)
MB=6x-2
or, B=6x-2-M......eqn (ii)
Now,
from eqn (i) and (ii)
x+8-M=6x-2-M
or, 8+2=6x-x-M+M
or, 10=5x
or, 10÷5=x
therefore, x=2
Again,
MB=6x-2
=6×2-2
=12-2
=10
is it correct
