To determine whether (−1,4) is a solution to the equation 3x+8y=29, substitute ...-1... for x and ...4... and for y.

In a pair of values like (-1, 4), the first coordinate, or entry, occupied by -1 always represents x.

Similarly, the second coordinate occupied by 4 represents y.

Answer: substitute ...-1... for x and ...4... and for y.

The angle measure of a triangle is shown in the diagram, what is Twh value of x?

seropon [69]

Answer:

$x = 28$

Step-by-step explanation:

$50 + (2x) + (3x - 10) = 180$

$180-50=130$

$(2x) + (3x - 10) = 130$

$5x - 10 = 130$

$5x = 130 + 10$

$5x = 140$

$\frac{5x}{5} = \frac{140}{5}$

$x= \frac{140}{5}$

$x = 28$

Find the 6th term of the sequence with t1 = -4 and tn = 5tn-1

Sergeu [11.5K]

! hello : 
t1 = -4 and tn = 5tn-1
n = 2 : t2 =5t1-1 =5(-4)-1 =-21
n = 3 : t3=5t2-1 =5(-21)-1 =-106
n = 4 : t4 =5t3-1 =5(-106)-1 =-531
n = 5: t5 =5t4-1 =5(-531)-1 =-2656
n = 6 : t2 =5t5-1 =5(-2656)-1 =-13281
