Answer:
The value of y is 18 at x = 70
Step-by-step explanation:
The equation of the directly proportional is y = k x, where k is the constant of proportionality.
∵ The value of y is directly proportional to the value of x
→ By using the equation above
∴ y = k x
∵ x = 140 and y = 36
→ Substitute them in the equation above
∴ 36 = k(140)
∴ 36 = 140k
→ Divide both sides by 140
∵ [tex]\frac{36}{140}[/tex] = k
∴ [tex]\frac{9}{35}[/tex] = k
→ Substitute the value ok in the equation
∴ y = [tex]\frac{9}{35}[/tex] x ⇒ equation of proportionality
∵ x = 70
→ Substitute in the equation to find y
∴ y = [tex]\frac{9}{35}[/tex] × 70
∴ y = 18
∴ The value of y is 18 at x = 70

of hotdogs and buns bought, in terms of h and b.
Answer:
8h + 12b
Step-by-step explanation:
Given that:
h = Hotdog packs
b = pack of buns
Hotdogs are packed in 8
Buns are packed in 12
The total number of hotdogs and buns bought expressed in terms of h and b is :
(Number of hotdog packs * number per pack) + (Number of buns pack * number per pack) =Total number of hotdog and buns

Answer:
[tex]k = -4[/tex]
Step-by-step explanation:
Given
[tex]\frac{3}{2} = k + \frac{11}{2}[/tex]
Required
Solve for k
[tex]\frac{3}{2} = k + \frac{11}{2}[/tex]
Apply subtraction property
[tex]\frac{3}{2} - \frac{11}{2} = k + \frac{11}{2} - \frac{11}{2}[/tex]
Apply addition property
[tex]\frac{3}{2} +(- \frac{11}{2}) = k + \frac{11}{2} +(- \frac{11}{2} )[/tex]
The fractions on the right represent an additive inverse.
So, we have:
[tex]\frac{3}{2} +(- \frac{11}{2}) = k[/tex]
Take LCM
[tex]\frac{3+(-11)}{2} = k[/tex]
Remove bracket
[tex]\frac{3-11}{2} = k[/tex]
[tex]\frac{-8}{2} = k[/tex]
[tex]-\frac{8}{2} = k[/tex]
[tex]-4 = k[/tex]
[tex]k = -4[/tex]

What is the gradient of the blue line?
Please help.
The gradient of the blue line given in the graph is 4 and this can be determined by using the slope intercept form and point slope form of the line.
Given :
The graph of the line is given.
The following steps can be used to determine the equation of a line given in the graph:
Step 1 - First determine the points through which the line passes through that is:
Points - (4,0) and (6,8)
Step 2 - Use the point-slope form of the line which is given by the equation:
[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the point on the line.
Step 3 - Substitute the value of the points in the above equation.
[tex]\dfrac{y-0}{x-4}=\dfrac{8-0}{6-4}[/tex]
Cross multiply in the above equation.
2y = 8(x - 4)
y = 4x - 16
Step 4 - Now, compare the above equation with slope-intercept form.
m = 4
