Answer:
c = a
Step-by-step explanation:
Let k be one of the root of the given equation.
According to the problem,
1/k will be the other root of the given equation.
We know that, product of the roots of the equation = c/a.
Therefore, k × 1/k = c/a.
or, 1 = c/a.
or, a = c [multiplying a on both sides].
The roots of the equation ax2 + bx + c = 0 will be reciprocal if a = c.
Therefore, a = c or c = a.
Is -2 a solution for a in the inequality 2a +6 > a
Answer:
a > −6
Step-by-step explanation:
Step 1: Subtract a from both sides.
2a + 6 − a > a − a
a + 6 > 0
Step 2: Subtract 6 from both sides.
a + 6 − 6 > 0 − 6
a > −6
How can I subtract 3x from both sides? Explanation and answer
Its not must that 3x have to be the one to be subtracted. You could take 8x as well.
But always subtract from the smaller one (in this case 3x) because its easier.
If you are subtracting 3x-3x and 8x-3x, the equation would be like
4 = 5x - 16
5x = 4+16
5x = 20
x = 4
If 3x + 13 = 19, find the value of 2x + 1. 2x + 1 =
Answer: 7.4
Step-by-step explanation:
3x + 13 = 19
3x = 6
x = 2
Now substitute value of 'x' in the second equation:
2(2) + 1.2(2) + 1
= 4 + 2.4 + 1
= 5 + 2.4
= 7.4
Answer:
7.4
Step-by-step explanation:
The value of X is 2, so 3*2=6 6+13=19
So the second equation is 2*2=4 4+1.2*2=6.4 6.4+1=7.4

Answer:
A = [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
From the number line attached in the figure,
Number of small parts from number 0 to 1 on the given number line = 6
A is the point which lies at 5th part from 0.
Each small part represents the fraction = [tex]\frac{1}{6}[/tex]
Therefore, A represents the fraction = [tex]5\times \frac{1}{6}[/tex]
= [tex]\frac{5}{6}[/tex]
So A = [tex]\frac{5}{6}[/tex] will be the answer.

Please help. I suck at math. Can someone simply the expression -3x-7(x+4)?
Answer:
[tex] - 3x - 7(x + 4) \\ = - 3x - 7x - 28 \\ = - 10x - 28[/tex]
hope it helped you:)
Answer:
[tex]-10x-28[/tex]
Step-by-step explanation:
[tex]-3x-7(x+4)[/tex]
Expand by using distributive law: [tex]a(b+c)=ab+ac[/tex]
Therefore,
[tex]-3x-7*x+\left(-7\right)\cdot \:4[/tex]
[tex]-3x-7x-7\cdot \:4[/tex]
[tex]-3x-7x-28[/tex]
Add the x:

A square of an unknown side length x inches has one side length increased by 4 inches and the other increased
by 7 inches
(a) If the original square is shown below with side lengths marked as x, label the second diagram to represent the new rectangle constructed by increasing the sides as described above.
Answer:
Length of new rectangle = (x + 7) inches
Width of new rectangle = (x + 4) inches
Step-by-step explanation:
A rectangle is a quadrilateral that has opposite sides to be parallel and equal. While a square has all its sides to be equal.
Given that: the square has unknown side length x inches.
Increasing one of its length by 4 inches = (x + 4) inches
Increasing the other by 7 inches = (x + 7) inches.
The new lengths results to a rectangle with length (x + 7) inches, and a width of (x + 4) inches.
the label diagram to represent the new rectangle is shown in the diagram attached to this answer.

9x-4=3x-28 step by step
Answer:
Step-by-step explanation:
9x-4= 3x-28
We simplify the equation to the form, which is simple to understand
9x-4=3x-28
We move all terms containing x to the left and all other terms to the right.
+9x-3x=-28+4
We simplify left and right side of the equation.
+6x=-24
We divide both sides of the equation by 6 to get x.
x=-4

Given RT below, if S lies on RT such that the
ratio of RS to ST is 3:1, find the coordinates
of S.
Answer:
(-2, -3)
Step-by-step explanation:
If a segment having extreme ends as [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is divided by a point (x, y) in the ratio of m:n,
x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]
y = [tex]\frac{my_2+ny_1}{m+n}[/tex]
Since, a line RT has extreme ends as R(-5, 3) and T(-1, -5) then a point S(x, y) which divides RT in the ratio of 3 : 1 will be,
x = [tex]\frac{3(-1)+1(-5)}{3+1}[/tex]
= [tex]\frac{-8}{4}[/tex]
= -2
y = [tex]\frac{3(-5)+1(3)}{3+1}[/tex]
= [tex]-\frac{12}{4}[/tex]
= -3
Therefore, coordinates of the point S will be (-2, -3).
