Answer:
younger sibling = 29 years
older sibling = 35 years
Step-by-step explanation:
Let
x = younger sibling
y = older sibling
x + y = 64 (1)
The older sibling was born 6 years before their young sibling
x = y - 6 (2)
Substitute x = y - 6 into (1)
x + y = 64
y - 6 + y = 64
2y = 64 + 6
2y = 70
y = 70/2
y = 35 years
Substitute y = 35 into (2)
x = y - 6
x = 35 - 6
x = 29 years
The scale factor is what you will use to make a whole shape bigger. For example if I have a square that all sides are 3 cm and the scale factor is 5 then the new square would have all sides 15 cm. So the length multiplied by the scale factor gives you the new length so then you take the new measurements and multiply them to get your new area. Hope this helps!!!!
Answer:
Solving for x. Want to solve for y instead?
1 Factor out the common term 44.
4(7x+8y)=884(7x+8y)=88
2 Divide both sides by 44.
7x+8y=\frac{88}{4}7x+8y=
4
88
3 Simplify \frac{88}{4}
4
88
to 2222.
7x+8y=227x+8y=22
The minimum value of g(x) is -3. This is a parabola with minimum value of -3 when x = 0.
f(x) will approach the values of -3 when x approaches negative infinity but will never reach that value
So b and d are true
