Answer:

2. 88, 3. 40, 4. 48, 5. 20

Step-by-step explanation:

first multiply&divide, then calculate from left to right

2. 5 · 4² + (2 · 3 + 2) = 5 · 16 + 6 + 2 = 88

3. (4 + 3)² - 12 + 3 = 49 - 12 + 3 = 40

4. 64 ÷ 4 · 3 = 16 · 3 = 48

5. 3² - 4 + 5 · 3 = 9 - 4 + 15 = 20

A figure has a vertex at (5,2). If the figure has line symmetry about the x axis, what are the coordinates of another vertex of

Fiesta28 [93]

X axis is the ones that goes left and right

(x,y)

symetric about the x axis means that the vertical distance from the x axis is the same for 2 points that are symetric about the x axis

y is height

(x,y)
(5,2)
2 is height
distance from x axis
therefor the other point is -2
(5,-2)

the other vertex is at (5,-2)

Marked(10)/total = 3/20 (from sample)

total/10 = 20/3 (inverting the above proportion)

total = 10•20/3 = 200/3 ≈ 67

In March, there will be two conferences: one for math and one for history. So far, 7 people have signed up for the math conferen

otez555 [7]

Answer:

After 4 days, the number of people attending both conferences be the same.

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$f(x) = 7+2x$

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$g(x) =11+x$

Both conference will have same number of people when

$f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4$

Thus, after 4 days, the number of people attending both conferences be the same.
