Answer:
Frankie will need to babysit for 4.4 time.
Step-by-step explanation:
We are given the following in the question:
Money earned by Frankie each times he babysits = $5
Money saved = $30
Total money Frankie wants to save for a skateboard = $52
Amount of money to be saved =
Total amount of money Frankie wants to save for a skateboard - Money saved already
He needs to save $22 more.
Let x be the number of times Frankie will need to babysit.
Thus, we can write the equation:
Thus, Frankie will need to babysit for 4.4 time.
Answer:
Distance D = √ [(2 - x)^2 + (3 - 4x^3)^2].
Step-by-step explanation:
Use the distance formula:
D = √[(x2 - x1)^2 + (y2 - y1)^2].
So here it is
D = √[(2 - x)^2 + (4 - y)^2] where x,y is any point on the curve.
D = √[2 - x)^2 + (4 - (4x^3 + 1))^2]
D = √ [(2 - x)^2 + (3 - 4x^3)^2]
Answer:
D. x < 3
Step-by-step explanation:
3x + 7 < 16
To solve, we have to isolate x.
3x + 7 < 16
Subtract 7 from both sides :
3x < 9
Divide 3 from both sides :
x < 3
Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.
Answer:
This is slope-intercept form: y = (-3/4)x + 3
The slope is: -3/4
The y-intercept is: 3
Step-by-step explanation:
3x + 4y - 12 = 0
Isolate y
3x - 3x + 4y -12 + 12 = -3x + 12
Simplify
4y = -3x + 12
Divide 4 on each side to get y by itself
4y/4 = -3x/4 + 12/4
Simplify
y = (-3/4)x + 3
This is slope-intercept form: y = (-3/4)x + 3
The slope is: -3/4
The y-intercept is: 3
