3x+y=4 write the equation in slope intercept form​

Mathematics

LekaFEV [45]3 years ago
6 0

Answer:

y = -3x + 4

Step-by-step explanation:

sorry im late

but all you have to do is isolate the y

so to do that we have to get rid of the 3x

3x + y = 4

in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y

3x + y = 4

-3x          -3x

y = -3x + 4

and now y is isolated

anastassius [24]

Step-by-step explanation:

$1.80 per pound

The amount she's supposed to buy it is

1.80 × 12.5 = $22.5

Can someone help me on this math problem.
nekit [7.7K]

In the rhombus, the diagonals are perpendicular.

We know, the sum of the measures of the triangle is equal 180°.

Therefore we have the equation:

(2x-15)+3x+90=180

2x-15+3x+90=180        <em>combine like terms</em>

(2x+3x)+(-15+90)=180

5x+75=180        <em>subtract 75 from both sides</em>

5x=105              <em>divide both sides by 5</em>

\boxed{x=21}

<h3>Answer: x = 21°</h3>

Graph the quadratic function <br> F(x)=3x^2+6x-24
Oliga [24]
For this case we have the following function:
 F (x) = 3x ^ 2 + 6x-24
 We observe that it is a quadratic equation.
 The graph is therefore a parabola.
 Its cut points are:
 (-4, 0)
 (2, 0)
 Answer:
 
See attached image to see graph of the function
