Answer:

Step-by-step explanation:

The equation for a line can be written in slope-intercept form:

$y = mx + b$

Where $m$ is the slope of the line and $b$ is the y-intercept.

Since we know " $y$ increases by $4$ when $x$ increases by $1$ ", that tells us that the slope of the line is $4$ .

$y = 4x + b$

To figure out the y-intercept, $b$ , we can plug in the coordinates given in the problem to the point that the line passes through, $(2, -1)$

$1 = 4(2) + b$

$1 = 8 + b$

$b = -7$

Therefore, the equation of the line is $y = 4x - 7$

Which expressions are equivalent to the one below? Check all that apply. 36x/6x

KonstantinChe [14]

For this case we must indicate expressions equivalent to:

$\frac {36 ^ x} {6 ^ x}$

We have to:

$36 ^ x = (6 ^ 2) ^ x = 6 ^ {2x}$

Rewriting the expression:

$\frac {6 ^ {2x}} {6 ^ x}$

To divide powers of the same base, we place the same base and subtract the exponents:

$6 ^ {2x-x} = 6 ^ x$

The options are:

A) $\frac {6 ^ {x} * 6 ^{ x}} {6^{x}}$

B) 6

C) $(\frac {36} {6}) ^ x$

D) $(36-6) ^ x$

E) $6 ^ x$

F) $36 ^ x$

So if we simplify option A) we have: $6 ^ x$

Option C) we have: $6 ^ x$

Option E) is $6 ^ x$

Answer:

Option A, C, E

What should be done to x^2 + 15x in order to create a perfect square?

lana [24]

$\bf \qquad \textit{perfect square trinomial} \\\\ (a\pm b)^2\implies a^2\pm \stackrel{\stackrel{\text{\small 2}\cdot \sqrt{\textit{\small a}^2}\cdot \sqrt{\textit{\small b}^2}}{\downarrow }}{2ab} + b^2 \\\\[-0.35em] ~\dotfill$

$\bf x^2+15x+\boxed{?}^2\implies \stackrel{\textit{we know the middle term is}}{2\sqrt{x^2}\cdot \sqrt{\boxed{?}^2}\implies 2x\boxed{?}}\qquad then\qquad 2x\boxed{?}=15x \\\\\\ \boxed{?}=\cfrac{15x}{2x}\implies \boxed{?}=\cfrac{15}{2}\qquad \impliedby \textit{we should add that much \underline{squared}} \\\\[-0.35em] ~\dotfill\\\\ x^2+15x+\left( \cfrac{15}{2} \right)^2\implies \left(x+ \cfrac{15}{2} \right)^2$

Which expressions are equivalent to 4^3 x 4^-5? Choose all answers that are correct. A) 4^-2 B) 1/16 C) 4^-15 D) 0.0625 E) 16^-1

astraxan [27]

The given expression is

$4^3 * 4^{-5}$

Here we have to use the product rule of exponent, according to which in case of multiplication, we have to add the exponents, that is

$4^3 * 4^{-5} = 4^{3-5} = 4^{-2}$

So out of the given options, correct option is A .

Which set of points is not coplanar?

spin [16.1K]

we know that

Coplanar points are three or more points which lie in the same plane. Remember that a plane is a flat surface which extends without end in all directions. Any three points in 3-dimensional space determine a plane.

case a) points A, B, E

Any group of three points determines a plane

The points A,B,E are coplanar

case b) points A, B,C,E

The four points do not belong to the same plane

The points A,B,C,E are not coplanar

case c) points B, C, D

Any group of three points determines a plane

The points B, C, D are coplanar

case d) points A,B, C, D

The base of the pyramid is a flat surface, the four points lie in the same plane

The points A,B, C, D are coplanar

therefore

the answer is the option

points A, B, C, E are not coplanar
