Px+76=Qx+76

Px = Qx

P = Q

so A and C is the answer

The answer is A.

Explanation: It’s asking which of those will make the equations the exact same.

When asked for infinitely many solutions, it’s asking for which one is the same line.

If they’re the same line, they are on top of each other and therefore always touching.

An angle in standard position measures -7pi/6 radians.

sukhopar [10]

Answer:

Quadrant II

Step-by-step explanation:

We can convert $-\frac{7\pi}{6}$ radians to degrees by multiplying by $\frac{180}{\pi}$ to get $-210^{\circ}$ .

$-210^{\circ}$ means we are rotating $210^{\circ}$ clockwise, so you would end up in Quadrant II.

What is the slope of the line passing through the point(2,-1) and the origin.

tiny-mole [99]

Answer:

- 1/2

Step-by-step explanation:

(0,0) (2,-1)

m = difference of y/difference of x = (-1 - 0) / (2 - 0) = - 1/2

y = - 1/2 x

I need help I don’t know how to do it

daser333 [38]

If a line is drawn across the shape connecting two of the angles it makes two triangles. The sum of the angles in a triangle is 180 degrees.
Since this shape makes two triangles the sum of the inside angles is 2 * 180 = 360 degrees

(2x - 17) + 90 + x + 59 = 360
combine like terms
3x + 132 = 360
3x = 360 - 132
3x = 228
x = 76

For which inequality would x = 8 not be a solution?

Naya [18.7K]

Put the value of x to the inequality:

$4x+3 > 0\\L=4(8)+3=32+3=35;\qquad R=0;\qquad L > R\ CORRECT\\\\9x-5 < 100\\L=5(8)-5=40-5=35;\qquad R=100;\qquad 35 < 100\ CORRECT\\\\x+4\leq10\\L=8+4=12;\qquad R=10;\qquad 12 > 10\ INCORECT (\leq)\\\\72\div x\geq4\\L=72\div 8=9;\qquad R=4;\qquad 9\geq4\ CORRECT$

Simplify 4 to the 7th over 5 squared all raised to the 3rd power.

Radda [10]

First write out your original equation.
${(\frac{ {4}^{7} }{ {5}^{2} } ) }^{3}$
Then use the law of exponents(power of a power) to simplify.
$\frac{ {4}^{21} }{ {5}^{6} }$
(Multiply the numerator and denominator exponents by the outside power.)

The answer is 4 to the 21st over 5 to the 6th.
