Hello,
To this question, It's only directly sum the equations:
y + y = 7x - 7x +7+19
2y = 0x + 26
2y = 26
y = 26 ÷ 2
y = 13
Now only to replace y = 13 in the equation of up or of down.
Then stay:
y = 7x + 7
13 = 7x + 7
7x = 13 -7
7x = 6
x = 6 / 7
Answer: (B) 8 cm
Step-by-step explanation:
A triangle has 3 sides.
In order for it to be a triangle, the sum of sides a and b must be greater than the length of side c.
Testing (A) 7cm:
7 + 9 > 16
16 > 16
False
Testing (B) 8cm:
8+9 > 16
17 > 16
True
Testing (C) 25cm:
9 + 16 > 25
25 > 25
False
Testing (D) 26cm:
9 + 16 > 26
25 > 26
False
Hello! First I would just look at the numbers without the zeros. So 28/7. This equals 4. Next cross out the same number of zeros on each side of the equation. In this instance, the 7 has one zero and the 28 has three so you can cross out one zero on each side. This leaves you with two zeros left over to add to the end of the 4. So you end up with 400.
I hope this helps!
Given : Function f(x) = x⁵ + (x + 3)²
The Question is to find the image of the given function at x = -1
In order to find the image of a function for a given value, We need to substitute the value in the respective function
f(-1) = (-1)⁵ + (-1 + 3)²
f(-1) = -1 + (2)²
f(-1) = -1 + 4
f(-1) = 3
