If (-1, y) lies on the graph of y=2^2x then y=

zubka84 [21]

Answer:

y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.

I believe the equation to be $y=2^{2x}$ . If you meant $y=2^2x$ , please let me know.

Thanks kindly.

Step-by-step explanation:

If (-1,y) lies on the graph of $y=2^{2x}$ , then by substitution we have:

$y=2^{2\cdot -1}$ .

We just need to simplify to determine y:

$y=2^{2 \cdot -1}$

Multiply the 2 and -1:

$y=2^{-2}$

Use reciprocal rule for exponents to get rid of the negative:

$y=\frac{1}{2^2}$

$2^2$ just means $2(2)$ :

$y=\frac{1}{2(2)}$

$y=\frac{1}{4}$ .

If two angles of a triangle measure 50 degrees and 85 degrees what is the measure of the third angle

Dvinal [7]

I think it's 45 because 50+85=135

*Remember in total the sum of all angles must be equal to 180
So in order to find the missing angle subtract 180-135=45.

45 is the measure of the 3rd angle.

Hope I helped :)

What is an x and y intercept for 14x+y=140

DanielleElmas [232]

140 divided by 14 is 10. So x is 10. And Y is 140. 140 divided by y (1) =140

3. In the expression 362 + 6, what will be the place value of the first digit of the quotient?

Hunter-Best [27]

Answer:

B. It will be the tens place because 6 is greater than 3.

Step-by-step explanation:

Since the question said "quotient," then I believe we have 362 ÷ 6 and not "362 + 6."

If we work on the quotient we have

$60\frac{1}{3}$

Obviously, the first digit in the quotient is 6 and it takes the place of tens.

Looking at the options, option B fits the most because 6 is actually greater than 3.

Therefore, the answer is option B, It will be the tens place because 6 is greater than 3.
