Answer:

B for the first one and it is correct.

x - 4 = - 7 for the second one and it is correct.

Step-by-step explanation:

Left hand panel

2x + 5 > 9

2x + 5 > 9 Subtract 5 from both sides.

2x + 5 - 5 > 9 - 5 Collect like terms

2x > 4 Divide by 2

x > 4/2

x > 2

Right Hand Panel

5x ≤ 30 Divide by 5

5x/5 ≤ 30/ 5

x ≤ 6

Your answer is Correct. (B)

Right hand panel

It's not the normal procedure. Usually when you have an absolute value the next step would be

x - 4 = 7 and you add four to both sides. The question is very poorly constructed and it is meant to fool you, but it didn't. You got this one right as well. Both correct.

Answer:

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Step-by-step explanation:

Given

$\frac{1}{4}$

$\frac{5}{10}$

$\frac{1}{2}>\frac{1}{3}$

$\frac{4}{8}>\frac{2}{6}$

$\frac{3}{5}>\frac{4}{5}$

Required

Select the unit fractions

If we are to go by what a unit fraction means: it means that the numerator of the fraction must be 1 and must be written as a single fraction i.e. $\frac{1}{2}$  and not as an inequality i.e.  $\frac{3}{5}>\frac{4}{5}$ 

Given the format of the question, what is required of the question is to select all correct inequality.

$(a)$ $\frac{1}{4}$

Convert to decimals

$0.25 < 0.167$ ---- This is not true because $0.25 > 0.167$

$(b)$ $\frac{5}{10}$

Convert to decimals

$0.5 < 0.5$ ---- This is not true because $0.5 = 0.5$

$(c)$ $\frac{1}{2}>\frac{1}{3}$

Convert to decimals

$0.5 > 0.33$ ---- This is true

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Convert to decimals

$0.5 > 0.33$ ---- This is true

$(e)$ $\frac{3}{5}>\frac{4}{5}$

$0.6 > 0.8$ --- This is not true because $0.6 < 0.8$

So: the true inequality is:

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,

algol [13]

Answer:

f(x) + 2 is translated 2 units up and -(1/2)*f(x) is reflected across x-axis.

Step-by-step explanation:

We have f(x) becomes f(x) + 2.

The y-intercept of f(x) is f(0), implies that y-intercept of f(x) + 2 is f(0) + 2. This means that the graph of f(x) is translated 2 units upwards.

Moreover, the region where f(x) increases will be the same region region where f(x) + 2 increases and there will not any change in the size of the figure.

Now, we have f(x) becomes -(1/2)*f(x).

The y-intercept of -(1/2)*f(x) is -(1/2)*f(0). This means that the graph is dilated by 1/2 units and then reflected across x-axis.

Moreover, the region where f(x) increases will be the opposite region region where -(1/2)*f(x) increases and the size of the figure will change as dilation of 1/2 is applied to f(x)
