Answer:
y = 26/7 or ≈ 3.71
Step-by-step explanation:
3y + 4y= 26
3y + 4y = 7y so,
7y = 26
Divide both side by 7, we got:
y = 26/7 or ≈ 3.71
Hope this helped :3
(-1,5)(2,4)
slope = (4 - 5) / (2 - (-1) = -1/3
y = mx + b
slope(m) = -1/3
use either of ur points (2,4)...x = 2 and y = 4
now sub and find b, the y int
4 = -1/3(2) + b
4 = -2/3 + b
4 + 2/3 = b
12/3 + 2/3 = b
14/3 = b
so ur equation is : y = -1/3x + 14/3....however, this is not ur answer because it is not in standard form.
y = -1/3x + 14/3
1/3x + y = 14/3....multiply both sides by 3
x + 3y = 14 <=== standard form
Answer:
SAS
Step-by-step explanation:
pretty sure since the angle z is connected to both right triangles the sides become congruent.
Answer:
when x=0 ,y=7
when x=-1, y=6
Step-by-step explanation:
Taking as equation 1 and 2 respectively
Inserting equation 2 in 1,
getting rid of 7 since its in both the sides with the same + signs,
when x=0 ,
y=7
when x=-1 , y=6
Step-by-step explanation:
y int is 4. negative slope so goes up on the left and down on the right. when x is neg infinity, y is pos infinity. when x is pos infinity, y is neg infinity. for slope, rise/run. how many units it goes up over how many units it goes to the side. 1/2 means for every 1 unit it goes up it goes over 2 units.
