7x = 31
The goal is to get x by itself on the left side. First, we divide both sides by 7 like this:
7x
7
=
31
7
When a numerator and denominator value are the same, then you can eliminate them by crossing them out:
7x
7
=
31
7
Then you are left with x by itself on the left like this:
x =
31
7
Finally, 31 over 7 is the same as 31 divided by 7. So, we enter that into our calculator to get the final answer:
x ≈ 4.429

6a^3b-1 . 2a^4b^2 I need help with my math
Answers
Answer:
this might help
Step-by-step explanation:
Simplifying
2a + 4b + 6a + -3b = 0
Reorder the terms:
2a + 6a + 4b + -3b = 0
Combine like terms: 2a + 6a = 8a
8a + 4b + -3b = 0
Combine like terms: 4b + -3b = 1b
8a + 1b = 0
Solving
8a + 1b = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-1b' to each side of the equation.
8a + 1b + -1b = 0 + -1b
Combine like terms: 1b + -1b = 0
8a + 0 = 0 + -1b
8a = 0 + -1b
Remove the zero:
8a = -1b
Divide each side by '8'.
a = -0.125b
Simplifying
a = -0.125b

Determine whether the given binomial is a factor of the polynomial p(x) . p(x)=x^ 3 +2x^ 2 -x-2;(x+2)
Answers
Answer:
[tex](x + 2)[/tex] isn't a factor of the polynomial [tex]p(x) = x^{3} + 2\, x^{2} - x - 2[/tex].
Step-by-step explanation:
By the Factor Theorem, for any constant [tex]a[/tex], [tex](x - a)[/tex] would be a factor of a polynomial [tex]p(x)[/tex] if and only if [tex]x = a[/tex] is a root (a zero) of that polynomial ([tex]p(a) = 0[/tex].)
In other words, [tex](x - a)[/tex] is a factor of polynomial [tex]p(x)[/tex] if and only if replacing all mentions of [tex]x[/tex] in [tex]p(x)\![/tex] with the constant [tex]a[/tex] would yield [tex]0[/tex].
For example, in this question, [tex](x + 2)[/tex] could be rewritten as [tex](x - (-2))[/tex] (value of the constant is [tex]a = (-2)[/tex].)
By the Factor Theorem, [tex](x - (-2))[/tex] would be a factor of the polynomial [tex]p(x) = x^{3} + 2\, x^{2} - x - 2[/tex] if and only if replacing all mentions of [tex]x[/tex] in [tex]x^{3} + 2\, x^{2} - x - 2[/tex] with [tex](-2)[/tex] evaluates to [tex]0[/tex].
Replacing all mentions of [tex]x[/tex] in [tex]x^{3} + 2\, x^{2} - x - 2[/tex] with [tex](-2)[/tex] gives:
[tex](-2)^{3} + 2\, (-2)^{2} - (-2) - 2[/tex].
Simplify:
[tex]\begin{aligned}& (-2)^{3} + 2\, (-2)^{2} - (-2) - 2 \\ =\; & (-8) + 8 + 2 - 2 \\ =\; & 0\end{aligned}[/tex].
Since [tex]p(-2) = 0[/tex], [tex](x - (-2))[/tex] (or equivalently, [tex](x + 2)[/tex]) is indeed a factor of the polynomial [tex]p(x)[/tex].

All the angles of square are equal and 90° eachTherefore,
[tex]\sf{\angle{MHA = }}{\sf{\angle{ MHT/2}}}[/tex]
[tex]\sf{\angle{MHA = 90°/2}}[/tex]
[tex]\sf{\angle {MHA = 45°}}[/tex]

WYXV is quadrilateral.
the reason are the undefined angles at W and V (they are equal, but not necessarily 90°, so the shape could shrink or extend between W and V)
ABCD is a rectangle.
AB and CD are parallel and equally long. and C is 90°.
that means then that the other angles must be 90° too, or either the parallel or equally long criteria would be violated.
PQSR is a parallelogram.
PQ and RS are parallel and equally long.
that means that PR and QS must also be parallel and equally long. we just don't know the angles, they could be anything. and therefore this is not a rectangle but a more generic parallelogram.

Write the equation of the line in standard form with y-intercept
of 7 and passes through the point (1,5).
Answers
Answer:
2x+y=7
Step-by-step explanation:
Hi there!
We are given that a line has a y intercept of 7 and passes through the point (1,5)
We want to write the equation of this line in standard form, which is ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot equal zero, and a cannot be negative
To start, we can write the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We are given that the y intercept is 7, so we can plug it in as b into the equation.
Here is the equation of the line so far:
y=mx+7
Now we need to find m
as the equation passes through the point (1,5) we can use it to help solve for b.
Substitute 1 as x and 5 as y into the equation.
5=m*1+7
Multiply
5=m+7
Subtract 7 form both sides
-2=m
Substitute -2 as m into the equation
y=-2x+7
This is the equation in slope-intercept form
However, remember that we aren't done, as the problem wants us to have the equation in standard form
In standard form, the terms containing x and y are on the same side; right now, they are on opposite sides.
So we can add -2x to both sides in order to move it to the left side
y=-2x+7
+2x +2x
______
2x + y = 7
This is the equation of the line in standard form.
Hope this helps!
