Answer:

B. y = 31

Step-by-step explanation:

Subtract 228 from both sides

4y + 228 - 228 = 352 - 228

4y = 124

Divide both sides by 4 to solve for y

4y / 4 = 124 / 4

y = 31

The length of the missing side b would be 16m

Step-by-step explanation:

What is the value of x? What is the measure of angle QOR? What is the measure of angle ROS?

Veseljchak [2.6K]

Answer:

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

$(x + 5) + (2x + 7) = 90\\ 2x + x + 5 + 7 = 90 \\ 3x + 12 = 90 \\ 3x = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26$

Sub x in

$(x + 5) \\ 26 + 5 = 31$

and

$(2 \times 26 + 7) \\ = 52 + 7 \\ = 59$

What’s all input for f(x)=3

defon

Answer:

all inputs are equal to 3

Step-by-step explanation:

$f(x) = 3 \\ = 3 \times 1\\ = 3 \times {x}^{0} \\ anything \: raised \: to \: 0 \: is \: 1 \\$

$\\ substituting \: any \: value \\ \: of \: x \: in \: f(x) \\ f(3) = 3 \times {3}^{0} \\ = 3 \times 1 \\ = 3 \\$

$\\ similarly \: all \: values \: of \: x \: will \\ give \: 3$
