Answer:

x=7

Step-by-step explanation:

8x – 2y = 48

Let y=4

8x - 2(4) = 48

8x - 8 = 48

Add 8 to each side

8x -8+8 = 48+8

8x = 56

Divide each side by 8

8x/8 = 56/8

x = 7

Answer:

x = 7

Step-by-step explanation:

since we know y = 4, we can plug this into the equation to find x

8x - 2y = 48

8x - 2(4) = 48

8x - 8 = 48

8x = 56

x = 7

Please can anyone help me answer this question I'm really struggling with it

Anika [276]

Answer:

$v = {210cm}^{3}$

Step-by-step explanation:

Formula for finding the volume of a triangular prism is given as:

$v = \frac{1}{2} \times b \times h \times l$

where,

b = breadth = 7cm

h = height = 6cm

l = length = 10cm

Thus,

$v = \frac{1}{2} \times 7cm \times 6cm \times 10cm$

$v = \frac{1}{2} \times 420 {cm}^{3}$

$v = \frac{ {420cm}^{3} }{2}$

$v = {210cm}^{3}$

Determine if the relation is a function if so state the domain and range

Sedaia [141]

Answer:

Function - Yes

Domain - [-3,0,3,4]

Range - [1,2,2,5]

Step-by-step explanation:

In a function, x-values cannot repeat and in this relation, x's do not repeat, therefore it is a function. The domain is the x-values on the graph from least to greatest; so to find the domain, simply take the first value of each coordinate and order them from least to greatest. Then, the range is the y-values, so to find the range take the second value from each coordinate and order them from least to greatest.
