The solution of the inequality is the shaded area below the solid line (the gray area)

The slope of the solid line is negative

The y-intercept of the solid line is positive

The equation of the solid line is equal to  

therefore

the equation of the inequality is equal to

Answer:

B) $400 in 5%, $600 in 7%

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 6.6/100

r = 0.066 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 10,000.00(1 + 0.066/12)(12)(7.5)

A = 10,000.00(1 + 0.0055)(90)

A = $16,382.75

Therefore, you will need to invest $400 in 5%, $600 in 7% acoounts

Answer:

a = (13 m) / (sec^2)

Step-by-step explanation:

Force equation:  F = ma

yields a = F/m

Here F = 26 N and m = 2 kg, so

a = (26 N) / (2 kg) = (13 m) / (sec^2)

Answer:

b

Step-by-step explanation:

The square of the given numbers 3, 4, and 5 are 9, 16, and 25 respectively.

The square of a number is the product of the number with itself. Therefore, if there is a number x then its square will be the product of x and x. It is denoted by 2 in superscript form over the number whose square is needed to be calculated.

The squares of the given numbers are,

3² = 3 × 3 = 9

4² = 4 × 4 = 16

5² = 5 × 5 = 25

Hence, the square of the given numbers 3, 4, and 5 are 9, 16, and 25 respectively.

Answer: i believe that the answer is B :)

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

We can either use the graph or the chart.

For this question it'll be easier to use the graph.

First find the y-intercept (that were your line meet the y-axis)

y = 4

Then find the slope ([tex]\frac{rise}{run} = \frac{2}{1} = 2[/tex])

Slope = 2

Then plug them into the equation: y = mx + b

m = slope = 2

b = y-intercept = 4

y = 2x + 4

Therefore, the answer is A

Answer:

scale factor(k)=23

A(x,y)=A'(kx,ky)

Let's do by using this formula

C(9,0)=C'(kx,ky)(here x=9 and y=0)

C(9,0)=(23*9,23*0)

C(9,0)=(207,0)

A(0,3)=A'(kx,ky)(here x=0 and y=3)

A(0,3)=A'(23*0,23*3)

A(0,3)=A'(0,69)

How it can be fixed => [tex] \frac{8x}{8} = \frac{4}{8} [/tex]

[tex] x = \frac{1}{2} [/tex] (correct answer)

Step-by-step explanation:

The student solved the problem correctly up to the second step where 6 was added to both sides of the equation.

The mistake he made was in his division.

Thus, instead of dividing both sides by 8, he divided both sides by 4, which is incorrect.

Answer:

mRS = 116

Step-by-step explanation:

If Segment SR ≅ TU then, arc SR ≅ arc TU

Thus, 6x - 28 = 4x + 20

                       ^ ( note that this is the equation we will use to solve for x )

6x - 28 = 4x + 20  

step 1 add 28 to each side

28 + -28 cancels out

28 + 20 = 48

we now have 6x = 4x + 48

step 2 subtract 4x from each side

6x - 4x = 2x

4x - 4x cancels out

we now have 2x = 48

step 3 divide each side by 2

2x / 2 = x

48 / 2 = 24

we're left with x = 24

Now to find the value of arc RS we substitute x with 24 in arc RS' given expression

arc RS = 6x - 28

* substitute x with 24 *

arc RS = 6(24) - 28

6 * 24 = 144

144 - 28 = 116

Hence, arc RS = 116

Answer:

Answer : mRS equals 116.
