Answer:

y = (3/4)x + (5/2)

Step-by-step explanation:

Just use the formula of,

;(y - y(coordinate)) = slope × [(x - x(coordinate))]

; y - 4 = 3/4(x - 2)...then multiply (3/4) into the bracket,

;y - 4 = (3/4)x - 3/2...then move 4 to the right hand side of the equation,

; y = (3/4)x + (5/2)

What is the measure of angle SQR?

Mademuasel [1]

Answer:

4x°= 4x18= 72°=measure of angle SQR

Step-by-step explanation:

6x +4x = 180

10x = 180

x = 180/10

x= 18°

because m L SQR =4x°

now place the value of x in the above equation

m L SQR = 4 x(18°)= 72°

The equation of the piecewise function f(x) is below. What is the value of f(3)?

JulijaS [17]

Option B: 5 is the value of f(3)

Explanation:

The equation of the piecewise function is given by

$f(x)=\left\{\begin{aligned}-x^{2}, & x$

We need to find the value of $f(3)$

The value of the function f can be determined when $x=3$ by identifying in which interval does the value of $x=3$ lie in the piecewise function.

Thus, $x=3$ lies in the interval $x\geq 0$ , the function f is given by

$f(x)=x+2$

Substituting $x=3$ in the function $f(x)=x+2$ , we get,

$f(3)=3+2$

$f(3)=5$

Thus, the value of $f(3)$ is 5.

Therefore, Option B is the correct answer.

The difference of two numbers is 16 and the sum of their squares is 130. What are the numbers.

Korvikt [17]

x - y = 16
x^2 + x^2 = 130

----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108

The table shows the distance in feet, y, that a rocket traveled in x seconds.

Murrr4er [49]

Answer:

The correct option is D. y = 25 $x^{2}$ .

Step-by-step explanation:

i) From the table and our own observation and a trial and error approach we

can clearly see that the equation that matches y in feet ( the distance

traveled by the rocket) and x in seconds ( the time elapsed) is given by the

equation y = 25 $x^{2}$

Therefore the correct option is D. y = 25 $x^{2}$ .
