Answer:

-4 ≤ y ≤ 8

Step-by-step explanation:

The range is the set of y-values for which the function is defined. When we are asked to find the range of a function (given in a graphical form), we look from which y-value (lowest) till which y-value (highest) the function is graphed for (defined for).

First, looking at the y-axis, we see that 5 bars in the coordinates is 10 units, so each bar is :

10/5 = 2 units

Now, looking at the lowest value, we see that it is 2 units from y = 0, so that is at:

y = -2 * 2 = -4

Now, looking at the highest value, we see that it is 4 units from y = 0, so that is at:

y = 4 * 2 = 8

So, the range is from y = -4 to y = 8. This can be written as:

-4 ≤ y ≤ 8

A math test is worth 100 points and has 38 problems. Each problem is worth either 5 points or 2 points. How many problems of eac

Natasha_Volkova [10]

Let x be the number of 5 points question.
Let y be the number of 2 points question.

Total number of questions is 38
x + y = 38

Total points is 100
5x + 2y = 100

x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)

From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8

There are 8 5-point questions and 30 2-point questions

Which expression is equivalent to Assume x > 0 and y 0.

Svetach [21]

we have

$\sqrt{\frac{55x^{7}y^{6}}{11x^{11}y^{8}}}$

we know that

$\sqrt{\frac{55x^{7}y^{6}}{11x^{11}y^{8}}} =\sqrt{\frac{55}{11}\frac{x^{7}}{x^{11}}\frac{y^{6}}{y^{8}}} \\ \\= \sqrt{\frac{5}{x^{4} y^{2}}} \\ \\ =\frac{\sqrt{5}}{x^{2} y}$

therefore

<u>the answer is</u>

The expression equivalent is $\frac{\sqrt{5}}{x^{2} y}$

Please solve for M<QTR

Andru [333]

Answer:

m∠QTR = 98°

Step-by-step explanation:

From the picture attached,

Radii of the circle are TQ and TR measuring equal lengths.

Therefore, ΔTQR is a isosceles triangle.

Opposite angles of the equal sides will be equal in measure.

m∠RQT = m∠TRQ = 41°

By angle sum theorem,

m∠RQT + m∠TRQ + m∠QTR = 180°

41° + 41° + m∠QTR = 180°

m∠QTR = 180° - 82°

= 98°

Therefore, m∠QTR = 98°
