Step-by-step explanation:
Y=-4x+3
2x+3y=19
2x+3(-4x+3)=19
2x-12x+9=19
-10x=10
X=-1
y=-4*(-1)+3=4+3=7
x=-1 y=7
Answer:
y=3x+2
Step-by-step explanation:
For a the equation is y=3x+2 because he makes 3 every hour (3x) and he already has 2 (+2).
For the graph you replace x with any number and solve. Plot the point.
Then you do it again but with a different x.
Finally you draw a straight line trough the 2 points.
Step-by-step explanation:
2/5×7500
2×1500
3000
RM=3000
B.
When two lines intersect they form two pairs of opposite angles.
Vertical angles are always congruent, which means that they are equal.
so m<7 = m<8 or m<3y + 19 = m<5y-29
C. solve for y and measure <7 and <8
3y + 19 = 5y-29
5y - 3y = 19+29
2y = 48
y = 24
so
5y-29 = 5(24) - 29 = 91
3y + 19 = 3(24) + 19 = 91
so <7 = 180 - 91 = 89
<7 = <8 = 89
Os números são 1180 e 440. <span>¡Espero que esto ayude!</span>
