(10 points) Chip made his eggnog recipe which was 12% sugar, but it was not sweet enough for Dale. Dale made his recipe which was 20% sugar, but it was too sweet for Chip. How much of each eggnog do they need to mix to get 80 oz. of eggnog which has15% sugar concentration?

Answers

50 oz. of 12% sugar and 30 oz. of 20% sugar is needed to produce 80 oz. of 15% sugar.

Equation

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the amount of 12% sugar and y represent the amount of 20% sugar need to produce 80 oz. of 15% sugar. Hence:

x + y = 80   (1)

Also:

0.12x + 0.2y = 0.15(80)   (2)

From both equations:

x = 50, y = 30

50 oz. of 12% sugar and 30 oz. of 20% sugar is needed to produce 80 oz. of 15% sugar.

Consider the equation y = 3x - 1
Identify the slope and y-intercept and
sketch the graph.

Answers

The slope will be the number that always sits next to x. So the slope in this case is 3/1. Which is rise over run. If it was a fraction, like 1/3, that would mean that the slope is rise one, run three.
If you want to find the y-intercept, you do that by putting a zero in for x, so you want to find the point that the line intersects the y-axis. So x would be zero, and wherever that point is is the y-intercept. In this case:
y = 3x - 1

y = 3(0) - 1

3 times 0 is zero

y = - 1 So, the y-intercept is - 1, or (0,-1)


To sketch the graph, you just place any number in for x or y (x is easier in this case), and solve it.
For example, I am going to say that x equals two.

y = 3(2)-1

y = 6-1

y = 5

So, your point to put on the graph would be (2,5) (x,y)

Choose the equation of the line in slope-intercept form.
Perpendicular to the y-axis and has the point (-4,5).

A. y = -4
B. x = -4
C. y = 5
D. x = 5

Answers

Answer:

C)   y = 5

Step-by-step explanation:

Equation of a line in slope-intercept form:  y = mx + b

(where m is the slope (gradient) and b is the y-intercept)

If the line is perpendicular to the y-axis, the line will be parallel to the x-axis (horiztonal) and so the slope is zero.

Therefore, y = (0)x + b

⇒ y = b

We are told that the line passes through point (-4, 5).  Therefore, the y-intercept is 5.

So the equation of the line is:  y = 5
