Answer:

yes it does

Step-by-step explanation:

because the equation y=9x does not have a y-intercept (all slopes come in the form y=mx+b -- it can be written differently though) and since there is no 'b' that means the y-intercept is 0. So whenever there is no y-intercept, the slope starts at 0.

What is the value of x in the equation 4 . 10 X+52 3 +35x+1 5 ? :)

pashok25 [27]

Answer:

$x=-3$

Step-by-step explanation:

Given:

$4\frac{3}{10}-(2\frac{2}{5}x+5\frac{1}{2})=\frac{1}{2}(-3\frac{3}{5}x+1\frac{1}{5})$

Distribute to remove parentheses:

$4\frac{3}{10}-2\frac{2}{5}x-5\frac{1}{2}=-\frac{18}{10}x+\frac{6}{10}$

For simplification and clarity, reduce all mixed numbers to simplified common fractions:

$\frac{43}{10}-\frac{12}{5}x-\frac{11}{2}=-\frac{9}{5}x+\frac{3}{5}$

Combine like terms:

$-\frac{12}{5}x-\frac{6}{5}=-\frac{9}{5}x+\frac{3}{5}$

Add 6/5 to both sides, then add 9/5x to both sides:

$-\frac{3}{5}x=\frac{9}{5}$

Divide both sides by -3/5 to isolate x (recall dividing by a number is equal to multiplying by its reciprocal):

$x=\frac{9}{5}\cdot -\frac{5}{3}, \\x=\frac{-9}{3},\\x=\boxed{-3}$

Work out the value of x :)

Nataliya [291]

Answer:

x=67.5

Step-by-step explanation:

A full circle is 360°, and the right angle is 90°. The rest of the angle is 270°, or 4x (from 3x+x).

4x = 270

x=67.5

Urgent! Quadrilateral ABCD is inscribed in the circle. What is the measure of angle C?

AnnyKZ [126]

Answer: 92

Step-by-step explanation: Angles in an inscribed quad are supplementary and add to 360.

First solve for x:

2x+34=180

x = 73

Then, solve for c

3x + 49 + c = 360

3(73) + 49 + c = 360

268 + c = 360

c = 92

Name the set(s) of numbers to which –10 belongs. A. whole numbers, integers, rational numbers B. rational numbers C. integers, r

marishachu [46]

Hello!

Whole numbers are numbers without a decimal point, also known as an integer (ex. -4, 0, 3, 10).

Rational numbers are a number than can be turned into a simple fraction (ex. -3/1, 4/5, 1/3, 1.75)

Natural numbers are integers that are NOT negative, sometimes zero.

Therefore, the answer is A. whole numbers, integers, rational numbers.
