Answer:

Step-by-step explanation:

First, we should put this equation in slope-intercept form by isolating y.

Thus, we have:

$2x-\frac{4}{3}y=4\\ -\frac{4}{3}y=4-2x\\ y=\frac{3}{2}x-3$

The slope-intercept equation shows that the y-intercept is -3 and the slope is 3/2.

Only answer A meets these requirements.

Answer:

73 and -23 hope this helped hon :)

Step-by-step explanation:

y=-8x+9

plug in -8

y=-8(-8)+9

y=64+9

y=73

y=-8x+9

plug in 4

y=-8(4)+9

y=-32+9

y=-23

Solve each problem by forming a pair of simultaneous equations:

Diano4ka-milaya [45]

Answer:

5.5, 9.5

Step-by-step explanation:

Let x and y be the numbers

x+y = 15

x-y = 4

Add the two equations together to eliminate y

x+y = 15

x-y = 4

------------------

2x = 19

Divide by 2

2x/2 =19/2

x = 9.5

Now find y

x+y = 15

9.5+y = 15

Subtract 9.5

x = 15-9.5

x =5.5

Three families visited the local fair over a holiday weekend: the rawlins family spent $51 on admission for 2 children and 3 adu

Musya8 [376]

The matrix equation that can be solved to find all the respective costs is;

$\left[\begin{array}{ccc}2&3&50\\4&6&100\\2&5&80\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] = \left[\begin{array}{ccc}51\\90\\78\end{array}\right]$

<h3>How to create matrix equations?</h3>

Let cost of admission for children be x.

Let cost of admission for adults be y.

Let cost of admission for carnival tickets be z.

Thus, we have the simultaneous equation as;

2x + 3y + 50z = 51

4x + 6y + 100z = 90

2x + 5y + 80z = 78

Thus, writing this in matrix form gives;

$\left[\begin{array}{ccc}2&3&50\\4&6&100\\2&5&80\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] = \left[\begin{array}{ccc}51\\90\\78\end{array}\right]$
