How do I write x - y = 11 in slope-intercept form?

belka [17]

Answer:

y = x - 11

Step-by-step explanation:

Slope-intercept form: y = mx + b

Step 1: Subtract x from both sides

x - y - x = 11 - x

-y = 11 - x

Step 2: Multiply both sides by -1

-y * -1 = (11 - x) * -1

y = x - 11

Answer: y = x - 11

Answer:

The Answer is A. (x, y) → (x, -y)

Step-by-step explanation:

Reflections

R x-axis (x, y) → (x, -y)

R y-axis (x, y) → (-x, y)

R y=x (x, y) → (y, x)

R y = -x (x, y) → (-y, -x)

The point (1,-1) is on the terminal side of angle theta in standard position what are the values of sine cuisine and tangent of

pickupchik [31]

$\bf \textit{terminal point }\implies 
\begin{array}{lclcll}
(&1&,&-1)\\
&\uparrow &&\uparrow \\
&x&&y
\end{array}
\\\\\\
sin(\theta)=\cfrac{y}{r}
\qquad 
% cosine
cos(\theta)=\cfrac{x}{r}
\qquad 
% tangent
tan(\theta)=\cfrac{y}{x}\\\\
-----------------------------\\\\
\textit{so, what's the radius "r"?}\implies r^2=x^2+y^2\implies r=\sqrt{x^2+y^2}$

Triangle ABC is formed by two parallel lines and two other intersecting lines. Find the measure of each angle A, B, and of the t

Mamont248 [21]

Answer:

A = 61°

B = 72°

C = 47°

Step-by-step explanation:

Well, first of all, we can see that:

$61^{\circ}+47^{\circ}+B^{\circ}=180^{\circ}$

So, we can find angle B.

$B=180^{\circ}-47^{\circ}-61^{\circ}$

$B=72^{\circ}$

Now, we can see to that angle C is just 47°

Finally, we know that the sum of all angles in a triangle is 180°, so we have:

$B+A+C=180^{\circ}$

$A=180^{\circ}-47^{\circ}-72^{\circ}$

$A=61^{\circ}$

I hope it helps you!

Ralph bought a dozen widgets and it cost $30. how much will 80 widgets cost ?

Lesechka [4]

A dozen = 12

12 widgets = $30
80 widgets = $x

$12x = 30 \times 80 \\ 12x = 2400 \\ x = 200$

Answer : 80 widgets would cost $200.

Hope this helps. - M
