Identify the slope and y-intercept of the line y=3/5×-3
Answers
Answer:
slope = 3/5
y-intercept = -3
Step-by-step explanation:
This equation is formatted in slope-intercept form. The general structure of these equations are:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept. Therefore, to find the answer, see which variable the numbers from the original equation correspond with.
y = mx + b
y = (3/5)x - 3
slope = m = (3/5)
y-intercept = b = -3

John has four times as much money as his sister Debbie who has half as much as their friend David. Together the three children have $105. a) How much money does Debbie have? Answer b) How much money does John have? Answer.. c) How much money does David have? Answer.. (1)
Answers
Let's say that the money that each person has is equal to a letter:
A=Debbie, B=John, C=David.
Now we can write some equations.
"John has four times as much money as his sister Debbie who has half as much as their friend David."
B = 4A
A = 0.5C
"Together the three children have $105"
A+B+C=105
This is now a system of equations problem. Substitute to solve.
A + (4A) + C = 105
(0.5C) + 4(0.5C) + C = 105
3.5C = 105, so C = 30.
Plug this into the previous equations to get A=15 and B=60
So Debbie has $15, John has $60, and David has $30

Describe van Hiele Level 1 (analysis), Level 2 (informal deduction) and Level 3 (deduction). Demonstrate the difference by using a scalene, isosceles and equilateral triangle as an example to explain learner thinking at the three different levels.
Answers
The van Hiele theory describes how young people in schools learn geometry.
How to explain the theory?
Van Hiele theory postulates five levels of geometric thinking which are visualization, analysis, abstraction, formal deduction, and rigor. The levels use their own language and symbols
Analysis: At this level, students start analyzing and naming the properties of geometric figures.
Informal deduction: At this level pupils or students perceive relationships between properties and figures.
Deduction: At this level, students can give deductive geometric proofs. They are able to differentiate between necessary and sufficient conditions.
An equilateral triangle has all sides equal. In an isosceles triangle, two sides are the same length. In a scalene triangle, none of the sides are the same length.

The graph below shows how many cookies can be made depending on how many cups of flour are used. How many cookies will be made if 18 cups of flour are used?
192 cookies
96 cookies
48 cookies
288 cookies
Answers
Answer:
288
Step-by-step explanation:
Find the 18 on the x axis. Go up to the line. Then go left and you will be at 288 on the y axis.
You can also divide a known coordinate to find the rate of change, since the graph is proportional. Use (6, 96). y/x = rate of change
96/6 = 16.
Now multiply 18 and 16 to get the number of cookies.
18 x 16 = 288

All tick marks are equally spaced on each number line below. Find the unknown value (x) for
each. Be prepared to explain your reasoning.
Answers
By finding the value between consecutive tick marks, we will see that:
1) x = 20
2) x = 48
3) x = 9.5
How to find the values of X?
We know that each tick mark are equally spaced in the number lines below.
If you look at the first one (the already solved one). You can see that between the 4 and the 12 there are 4 ticks. If each tick has a value of T, we must have:
4 + 4*T = 12
4*T = 12 - 4 = 8
T = 8/4 = 2
Each tick values 2 units.
Between the 12 and the x there are 4 ticks, then:
x = 12 + 4*2 = 20
Now let's look at the second number line. There are 10 ticks between 25 and 140, then:
25 + 10*T = 140
10*T = 140 - 25 = 115
T = 115/10 = 11.5
And there are 2 ticks between 25 and the x, so:
x = 25 + 2*T = 25 + 2*11.5 = 48
x = 48.
Now the final number line. There are 8 ticks between 10 and 12, then:
10 + 8*T = 12
8*T = 12 - 10 = 2
T = 2/8 = 1/4 = 0.25
Now, the x is 2 ticks before the 10, then we have:
x = 10 - 2*T = 10 - 2*0.25 = 9.5
