Question

PLEASE ANSWER CORRECTLY ASAP: Solve this system of equations: y = x2 – 3x + 12 y = –2x + 14 Substitute the values of x, –1 and 2, into either original equation to solve for the values of y. What are the solutions of the system of equations? One solution is (–1, __ ) The second solution (2, ___)

Solution 1

First one, subsitute x=-1 for x

$y=(x)^2-3(x)+12$
$y=(-1)^2-3(-1)+12$
$y=1+3+12$
$y=16$
so one solution is (-1,16)

2nd one, subsitute 2 for x

$y=(x)^2-3(x)+12$
$y=(2)^2-3(2)+12$
$y=4-6+12$
$y=10$
the second soltuion is (2,10)

so one solution is (-1,16)
the second solution is (2,10)

Question

Suppose there is a relationship between independent and dependent variables represented by a scatterplot. Which statement is correct? The independent variable influences change in the dependent variable only if the points on the scatterplot go up from left to right. The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right. The dependent variable influences change in the independent variable only if the points on the scatterplot go up from left to right. The dependent variable influences change in the independent variable whether the points on the scatterplot go up or down from left to right. Mark this and return

Solution 1

If there is a relationship between dependent and independent variables represented in a scatterplot, The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.

The independent variable is the one that influences the dependent variable. If there is a relationship between them, it doesn't matter the direction of the points in the scatterplot, but the correlation coefficient.

If the points go up from left to right, the correlation is called direct correlation (increasing the value of the independent variable will increase the value of the dependent variable).

If the points go down from left to right, the correlation is called inverse correlation (increasing the value of the independent variable will decrease the value of the dependent variable)

Have a nice day.

Solution 2

Answer:

B: The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.

dependent means it depends on something, such as the independent variable that will change it

Question

Aiden built a tower that is 18 inches tall and that is 3 times as tall as Anna tower.. Anna tower is 6 inches tall... Can you write an equation to match this story?

Solution 1

Let the height of the tower be T

Let the height of the Anna tower be A

T = 3*A

You can also fit the values to check.

18 = 3*6

Question

A circle has a circumference of 49 pi what is the radius of the circle.

Solution 1

Circumference = πD

πD = 49π

D = 49

Radius = Diameter ÷ 2 = 49 ÷ 2 = 24.5

Answer: 24.5 units

Solution 2

Circumference = π · d

49 = diameter
π = pi

Radius = Half of diameter

Divide radius by 2:

49 ÷ 2 = 24.5

Answer = Radius is 24.5

Question

A flatbed truck is loaded with 7,000 pounds of bricks. How mqny tons of bricks are on the truck

Solution 1

A ton is equal too 2,000 pounds so you set it up as (7000/2000). You divide and your answer is 3.5 tons

Solution 2

1000 pounds = 0.5 tons

Convert:-

7000 pounds = 3.5 tons

3.5 tons of bricks are on the truck.

Question

Solve for r. k=ar/p a r=ka/p b r=kap c r=kp/a d r=a/kp

Solution 1

Solve for r by simplifying both sides of the equation, then isolating the variable.
$r= \frac{kp}{a}$

hopefully i was of help, please mark brainly is possible

Question

The selling price of 25/4 kg of apples is rs.400 .at what rate per kg are the apples being sold?

Solution 1

25/4 kg = rs 400

Find 1 kg:
1 kg = 400 ÷ 25/4
1 kg = 400 x 4/25
1 kg = Rs. 64

Answer: Rs. 64/kg

Solution 2

25/4 kg = 6.25 kg = rs. 400

rs. 400 / 6.25 = the selling price per kg = rs. 64

The apples are being sold for rs. 64 per kg.

Question

An observer is 120 feet from the base of a television tower, which is 150 feet tall. find the angle of elevation of the top of the tower from the point where the observer is standing.

Solution 1

We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅

in this problem
opposite side angle ∅=150 ft
adjacent side angle ∅=120 ft
∅=angle of elevation
so
tan ∅=150/120--------> 1.25
∅=arc tan(1.25)---------> ∅=51.34°

the answer is
51.34°
