ra1l [238]3 years ago
4 0

Answer:

F = \frac{9C+160}{5}

Step-by-step explanation:

Given

C = \frac{5(F-32)}{9} ( multiply both sides by 9 to clear the fraction )

9C = 5(F - 32) ← distribute

9C = 5F - 160 ( add 160 to both sides )

9C + 160 = 5F ( divide both sides by 5 )

\frac{9C+160}{5} = F

What are the slope and y-intercept of the line described by the equation<br> y= 4x - 7?
Verdich [7]

Answer:

A. Slope: 4; y-intercept: (0-7)

Step-by-step explanation:

The equation given is in slope-intercept form, y =mx+b, where m is the slope and b is the y-intercept.

Our equation is y=4x -7,

Where m = 4 b = -7

If m = to the slope and b = to the y-intercept, our slope would be 4/1 or 4, and our y-intercept would be (0,-7).

The answer, A would be the best for the question.

Hope it helps!

What is the equation of the circle that has its center at -26,120 and passed through the origin
OlgaM077 [116]

well, first off let's check those two points, we know it's centerd at (-26 , 120) and we also know it passes through (0 , 0), so the distance between those two points is its radius

~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{0}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{-26}~,~\stackrel{y_2}{120})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~-26 - 0~~)^2 + (~~120 - 0~~)^2} \implies r=\sqrt{(-26)^2 + (120 )^2} \\\\\\ r=\sqrt{( -26 )^2 + ( 120 )^2} \implies r=\sqrt{ 676 + 14400 } \implies r=\sqrt{ 15076 } \\\\[-0.35em] ~\dotfill

\textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \hspace{5em}\stackrel{center}{(\underset{-26}{h}~~,~~\underset{120}{k})}\qquad \stackrel{radius}{\underset{\sqrt{15076}}{r}} \\\\[-0.35em] ~\dotfill\\\\ ( ~~ x - (-26) ~~ )^2 ~~ + ~~ ( ~~ y-120 ~~ )^2~~ = ~~(\sqrt{15076})^2 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (x+26)^2+(y-120)^2 = 15076~\hfill

1/150 : 2 = 1/200: X
NeTakaya

Answer:

The value of X is X=\frac{3}{2}

Step-by-step explanation:

Given : \frac{1}{150} : 2=\frac{1}{200} : X

To find : The value of X ?

Solution :

\frac{1}{150} : 2=\frac{1}{200} : X

Converting ratios into fraction,

\frac{\frac{1}{150}}{2}=\frac{\frac{1}{200}}{X}

\frac{1}{150\times 2}=\frac{1}{200\times X}

Cross multiply,

200X=300

X=\frac{300}{200}

X=\frac{3}{2}

Therefore, The value of X is X=\frac{3}{2}
