Lorico [155]

Answer:

bool b = isupper(x);

Step-by-step explanation:

I have written the expression for a char variable x.The isupper(x) will return true if the character x is upper case and false if the character x is lower case.

I have stored the returned value to a bool variable b .So the value of variable b will be true only when the x is in uppercase and false when b is lower case.

1/2(x+10)= 1/4 (x-8) x= <br> (must be a fraction)

Alex_Xolod [135]

Answer:

$x=-9\frac{1}{3}$

Step-by-step explanation:

$\frac{1}{2}(x+10)=\frac{1}{4}(x-8)$

$\frac{1}{2}x+5=\frac{1}{4}x-2$

$\frac{1}{2}x-\frac{1}{4}x=-5-2$

$\frac{3}{4}x=-7$

$x=-\frac{28}{3}=-9\frac{1}{3}$

K(2, 7), L(6, 12), M(13, 13), N(9.8) (Slope Formula) is it a parallelogram?

vredina [299]

angles and sides opposite one another on a parallelogram are congruent, we can say this is a parallelogram because there are congruent.

What in mathematics is a parallelogram?

A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal).
A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus.

Slope Formula: y2-y1/x2-x1

KL: 12-7/6-2 = 5/4

LM; 13-12/13-6 = 1/7

MN: 8-13/9-13 = 5/4

KN: 7-8/9-2 = 1/7

Since angles and sides opposite one another on a parallelogram are congruent, we can say this is a parallelogram because there are congruent.
