-1.75 7/-4=-1.75 u can use a couculater
Answer:
Step-by-step explanation:
y=3x+6
slope is 3, so y=3x+[unknown].
We insert the point (4,7) into the equation.
7=3*4+[unknown]
7=12+[-5]
so the answer is
y=3x-5
It was difficult to see the grid lines but i believe it is a reflection across the y-axis and a translation of (2,-7). Ry-axis T(2,-7)
Answer: y=5 x=1
Step-by-step explanation: to know the real zero you
First choose from the equation if x is equal to 1 and input it into the equation
Y= -3(1)+8
Y=-3+8
Y=5
Therefore
If
Y is 5 apply it to the equation
5=-3(1)+8
5=-3+8
5=5
5-5=0
Answer:
x = 1 and y = 4
Step-by-step explanation:
m² = 7x + 7; m³= 4y and m∧4 = 112
√(m∧4) = √112
∴ m² = √112
Hence, 7x + 7 = √112
(7x + 7)² = 112
49x² + 14x + 49 = 112
49x² + 14x - 63 = 0
7x² + 2x - 9 = 0
7x² + 9x - 7x - 9 = 0
x(7x + 9) - 1(7x + 9) = 0
(x - 1)(7x + 9) = 0
x - 1 = 0
∴ x = 1
When x = 1
m²= 7 + 7 = 14
m³= 4y and m∧4 = 112
Also m∧4/m²= m² = 112/14 = 8
Hence, m° = 2; m = 2 X 2 = 4; m² = 2 x 2 x 2 = 8; m³= 2 x 2 x2 x 2 = 16
m³ = 16 = 4y
∴ y = 16/4 = 4
