Answer:

(3, 2)

Step-by-step explanation:

The system of equations can be solved using elimination to eliminate one variable and solve for the other.  Given the two equations:

3x + 4y = 17 and -4x - 3y = -18, we need to have opposite coefficients to eliminate a variable.  Multiplying the first equation by '3' and the second by '4':

3(3x + 4y = 17) = 9x + 12y = 51

4(-4x - 3y = -18) = <u>-16x - 12y = -72</u>

                                      -7x = -21

                                        x = 3

Solve for y:  3(3) + 4y = 17 or 9 + 4y = 17

y = 2

yarga [219]

Answer:

V=378 inch³

Step-by-step explanation:

The package is in the shape of a cuboid. The volume of a cuboid is given by :

V = lbh

l=length, b=breadth and h=height

Area of base = 54 inch²

Height of box, h = 7 in

It means that, volume of the package is :

V = 54 × 7

V=378 inch³

So, the volume of the package is 378 inch³.

Can someone help me? I'm trying to find the slope form of 4x + 2y = 4.
Neporo4naja [7]
Here, Equation: 4x + 2y = 4
Divide the equation by 2, 
2x + y = 2
y = -2x + 2

Now, compare the equation with y = mx + c
Here, slope (m) = -2

In short, Your Answer would be -2

Hope this helps!

The diagram represents a reduction of a triangle by using a scale factor of 0.8.
Alekssandra [29.7K]

Answer:

4.8 inches

Step-by-step explanation:

<em>See comment for complete question</em>

Represent the larger triangle with 1 and the smaller with 2.

So, we have:

H_1 =6\ in -- height of 1

Required

Determine H2 --- Height of 2

To do this we apply dilation formula.

Original * Scale\ Factor = New

In this case:

H_1 * Scale\ Factor = H_2

Substitute 6 for H1 and 0.8 for Scale Factor

6* 0.8 = H_2

4.8= H_2

Hence, the height of the smaller triangle is 4.8 inches
