My name is Ann [436]3 years ago
4 0

Answer:

I believe it is -13=-10m+c

Step-by-step explanation:

We use the slope intercept form of y=mx+c. y is the y intercept and x is -10

We plug in y=-13 and x=-10 to get

-13=-10m+c

Chi chi can hit The golf ball 72 yards. Rory Can hit a golf ball 24 yards. How many times further can Chi chi hit a golf ball th
ivanzaharov [21]

Answer:

Chi chi canhit a golf ball three times further than Rory.

Step-by-step explanation:

To compare the distance between the two golfers, we can set up a ratio:

\frac{Chi chi Distance}{Rory Distance} = \frac{72}{24} =\frac{3}{1}

Since the distance that Chi chi can hit the ball is 3:1 the distance that Rory can hit the ball, than Chi chi can hit the golf ball three times further.  When reducing a ratio or fraction to lowest terms, you need to divide the numerator and the denominator by the same factor.  Since 72 can be evenly divided by 24, we can divide both the numerator and the denominator by 24 to get 3:1.

Solve for the variable. 3/4x = -24​
sleet_krkn [62]

Hello!

Answer:

\huge\boxed{x = -32}

3/4x = -24

To isolate the "x" variable, divide both sides by 3/4 (multiply by its reciprocal, or 4/3)

3/4x · 4/3 = -24 · 4/3

x = (-24 · 4) / 3

x = -32.

point f has coordinated (8,-1), point g is symmetric to point f with respect to the line y=x, what are the coordinates of point
Alex17521 [72]
If points f and g are symmetric with respect to the line y=x, then the line connecting f and g is perpendicular to y=x, and f and g are equidistant from y=x.

This problem could be solved graphically by graphing y=x and (8,-1).  With a ruler, measure the perpendicular distance from y=x of (8,-1), and then plot point g that distance from y=x in the opposite direction.  Read the coordinates of point g from the graph.

Alternatively, calculate the distance from y=x of (8,-1).  As before, this distance is perpendicular to y=x and is measured along the line y= -x + b, where b is the vertical intercept of this line.  What is b?  y = -x + b must be satisfied by (8,-1):  -1 = -8 + b, or b = 7.  Then the line thru (8,-1) perpendicular to y=x is     y = -x + 7.  Where does this line intersect y = x?

y = x = y = -x + 7, or 2x = 7, or x = 3.5.  Since y=x, the point of intersection of y=x and y= -x + 7 is (3.5, 3.5).

Use the distance formula to determine the distance between (3.5, 3.5) and (8, -1).  This produces the answer to this question.

HELPPPPPPPPPPPPPPPPWhich statements are true about the ordered pair(-1, -4) and the system of
Anastasy [175]

Answer:

When (-1,-4) is substituted into the second equation, the equation  is true.

The ordered pair (-1,-4) is a solution to the system of linear  equations.

When (-1,-4) is substituted into the first equation, the equation is  true.

Step-by-step explanation:

Given

x - y = 3

7x - y = -3

Required

What is true about (x,y) = (-1,-4)

To do this, we substitute -1 for x and -4 for y in both equations;

For x - y = 3

-1 - (-4) = 3

-1 + 4 = 3

3 = 3

<em>Hence: </em>(-1,-4)<em> is true for </em>x - y = 3<em></em>

For 7x - y = -3

7(-1) - (-4) = -3

-7 +4 = -3

-3 = -3

<em>Hence: </em>(-1,-4)<em> is true for </em>7x - y = -3
