What’s the value of y?

Answers

Answer 1

Answer:

c. 19

Step-by-step explanation:

This model is describing a function. You put in a number for x, in this case, the input of 7 on the side. You solve the equation with that x-value to get a y-value/output.

x=7

y=3x-2

y=3(7)-2

y=21-2

y=19

Line segment EG is partitioned by point F in the ratio 1:2. Point E is at E (0, 4), and point F is at (1, 3). What are the coordinates of point G?

(−1, 5)
(2, 2)
(3, 1)
(4, 0)

Answers

Answer:

(3, 1)

Step-by-step explanation:

The coordinates of point G is (c) (3,1)

The coordinate points are given as:

[tex]\mathbf{E = (0,4)}[/tex]

[tex]\mathbf{F = (1,3)}[/tex]

The ratio is given as:

[tex]\mathbf{m : n = 1 :2}[/tex]

Line ratio is given as:

[tex]\mathbf{(x,y) = \frac{mx_2 + nx_1}{m + n}, \frac{my_2 + ny_1}{m + n}}[/tex]

Point F is at the partitioned point.

So, we have:

[tex]\mathbf{(1,3) = \frac{1 \times x_2 + 2 \times 0}{1 + 2}, \frac{1 \times y_2 + 2 \times 4}{1 + 2}}[/tex]

[tex]\mathbf{(1,3) = \frac{x_2 }{3}, \frac{y_2 + 8}{3}}[/tex]

Multiply through by 3

[tex]\mathbf{(3,9) = (x_2, y_2 + 8)}[/tex]

By comparison, we have:

[tex]\mathbf{x_2 = 3}[/tex]

[tex]\mathbf{y_2 + 8= 9}[/tex]

Subtract 8 from both sides

[tex]\mathbf{y_2 = 1}[/tex]

Hence, the coordinates of point G is (c) (3,1)

9 yellow - ? red
3 * 3 - 2 * 3

Answer:Any number less than -13.

Step-by-step explanation:

If the number is real and rational and non-natural, this means that it can be any number in the negative number space.

Additionally, since the number has to be less than -13, then the number could be any number less than -13.

With all these things considered, the number is any number less than -13 that is real and rational.

Write an equation for a line parallel to
y = 3x - 1 and contains the point (-2, 8).

Answers

Answer:

y=3x+14

Step-by-step explanation:

Answer:

y = 3x + 14

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 1 ← is in slop- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation

To find c substitute (- 2, 8) into the partial equation

8 = - 6 + c ⇒ c = 8 + 6 = 14

y = 3x + 14 ← equation of parallel line

A new shopping mall is gaining in popularity. Every day since it opened, the number of shoppers is 20% more than the number of shoppers the day before. The total number of shoppers over the first 4 days is 671

Answers

Answer:

First term = a = 125

Step-by-step explanation:

Question: find the number of shoppers on the first day

This is a geometric progression question

The sum of the terms = 671

Sum of a geometric sequence,Sn = (ar^n - 1) / (r - 1)

Where,

n = number of term in the sequence.

a = first term in the sequence.

r = common ratio

r = 1 + 20%

= 1 + 20/100

= 1 + 0.2

= 1.2

n = 4 (first 4 days)

Sn = (ar^n - 1) / (r - 1)

Sn = 671 where n = 4

671 = {a × 1.2^(4) - 1} / 1.2 - 1

671 = {a × 2.0736 - 1} / 0.2

671 = (2.0736a - a) / 0.2

671 = 1.0736a / 0.2

671 = 5.368a

Divide both sides by 5.368

a = 671 / 5.368

a = 125

Step-by-step explanation:

Rational numbers are numbers that can be expressed as fractions. Rational numbers include finite values and repeating decimals that have a pattern.

Because all of the answer choices include decimals that have no predictable pattern of decimals, A must be correct.

0.318 is rational because it is finite. 0.3444... will continue to add 4 on to the end of the number, meaning it is repeating predictably, and it is rational.

Answers

Answer:

When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:

1) Square all 3 sides.

24^2= 576

29^2= 841

32^2= 1,024

2) Sum the squares of the 2 shortest sides.

576 + 841 = 1,417

3) Compare this sum to the square of the 3rd side.

if sum > 3rd side² Acute Triangle

It's an acute triangle.

if sum = 3rd side² Right Triangle

if sum < 3rd side² Obtuse Triangle
