Answer:
1/100 (1471 z + 2100)
0.01 (1471 z + 2100) the result I got
and the Factorization over the splitting field:
14.71 z + 21
63+82+m∠DCE=180
145+m∠DCE=180
m∠DCE=35
Answer:
y = - 7x - 26
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 7, thus
y = - 7x + c ← is the partial equation of the line
To find c substitute (- 5, 9) into the partial equation
9 = 35 + c ⇒ c = 9 - 35 = - 26
y = - 7x - 26 ← equation of line
Answer2 bags of stone only
Step-by-step explanation:
so you need to times up the amount the bags weight to the ones he already has 25*8=200 and 22.5*19=427.5 and 50*20=1000 the you subtract what he needs to use like he doesn’t need any cement bags nor sand he only needs 2 bags of stone
Answer:
at first , you need the sum of both equations . It will be like :
2y= 0 + 2
Y=1
_____
now that you know the value of Y , place it in the one of the equation that you like , forexample i place it in the second equation and find out that the value of x is ( -3/2)
1= 2X+5
-4=2X
X= -2
Hope it helps , good luck ^.^
