The ratio of the mass of the fruit to the mass of the yoghurt is 2:5
Which calculation will give the mass of the yoghurt?
175 divide 5 times 7 or 175 divide 7 times 5 or 175 divide 5 times 2 or 175 divide 7 times 2
What is the mass of the yoghurt (not the fruit and yoghurt - just the yoghurt, so it's not 175g)?
Answer:
Step-by-step explanation:
1. Solve the equations for x
2. Calculate the corresponding values of y
Insert the values into equation (1)
(a) x = 3
y = 3 - 1 = 2
One point of intersection is (3, 2).
(b) x = -2
y = -2 - 1 = -3
The second point of intersection is (-2, -3).
The diagram shows the intersection of the two graphs.
Answer:
(-2,-3) and (3,2)
Step-by-step explanation:
sub in x-1 into y
x^2 + (x-1)^2 = 13
x^2 + (x-1)(x-1)=13
x^2 + x^2 -2x +1 = 13
2x^2 -2x-12=0
solve for x by factoring (quadratic formula, product sum etc..)
x= -2 and 3
plug in those values into y=x-1 and solve for y
The sum is
Step-by-step explanation:
First term(a) = 1
Common difference(d)=2-1=1
No.of term(n)=50
Sn=n÷2(n+1)=50÷2(50+1)=1275
What is the meaning of the y-intercept of the linear model?
a) The initial value of the car is 14,000.
b) The average value of the car is 14,000.
c) The car’s value decreases by $875 each year after it was purchased.
d) The car’s value decreases by $16 each year after it was purchased.
Please help.
Answer:
Option a) The initial value of the car is 14,000
Step-by-step explanation:
we know that
The linear equation into slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
Remember that
The y-intercept is the value of y when the value of x is equal to zero
In this problem we have
so
The slope is equal to
The y-intercept is
therefore
is the value of the car for x=0 (initial value)
