You can do this by replacing x = -2y + 10 in second equation and solving for y then plug this value of y in first equation to find x then use these values of x and y in last equation to find zSHOW FULL ANSWER
To write the equation of a line, we need 1) a point on the line 2) it's slope
For the point, we just substitute in the equation of the line intersecting it with x=3 (because they share this point)
Therefore, 2*3-3y=6 --> That gives y=0
Then the point is (x1,y1)=(3,0)
We already have the slope : m=2
Now we should use this relation for the required line equation
(y-y1) / (x-x1) = m
Then (y-0) / (x-3) = 2
Then y = 2*x - 6
And that is the required form
where 2 is the slope and -6 is the intercept
Answer:
I think is A
Step-by-step explanation:
-7x -13 ≥ 8
+13 +13
-7x ≥ 21 (then, divide by -7 and when u divide by a negative number, the sign flip)
Answer: x ≤ -3
In order to calculate the number of loaves Roger can bake, we should calcculate how many times 3/4 (required butter for one loaf of bread) is included in 2 1/2 (amount of butter Roger has).
2 1/2=4/2+1/2=5/2
(5/2)/(3/4)=5*4/2*3=20/6=3,33
Roger can bake 3 loaves of bread.
