3×n2 - 4×n1 = 6

3×6 + 5×10= 68

DEFG is a rectangle. DF = 5x - 3and EG = x + 5. Find the value of x and the length of each diagonal.
erica [24]
d. x = 2, DF = 7, EG = 7
 
DF is equivalent to EG; Therefore, the equation would be like this:

5x - 3 = x + 5
Transfer 3 and x to their opposite side and change their signs.

5x - x = 5 + 3
4x = 8
Find x. Divide both sides by 4.

4x / 4 = 8 / 4
x = 2

Subsitute x in the equation to find the length of each diagonal.

DF = 5x - 3 = 5(2) - 3 = 10 - 3 = 7 ; DF = 7
EG = x + 5 = 2 + 5 = 7 ; EG = 7

Find the x and y intercept of 2x + 5y - 20
UNO [17]

Answer:

x=(10,0)

y=(0,4)

Step-by-step explanation:

Rewrite the equation so it is 5y=2x-20

Multiply both sides by 5

Then figure out the equation and you get the x intercept

Then put 10 into your new equation in the x spot and thats how you get y

Hope this helps:)

If my explaining is not good you can also use Math_way and it shows you all th steps too.
