Answers

For x = -5 the equation [tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex] is a true equation. Hence, OPTION (B) IS CORRECT.

We have the following equation -

[tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex]

We have to find the value of x that makes this equation true.

How can you say that the equation [tex]x^{2} = 2x[/tex] is a true equation at x = 0 and x = 2 ?

In order to prove that the equation is true at x = 2 and x = 0, we have to prove that the left hand side of the equation equals the right hand side of the equation, if we substitute 2 or 0 in place of x Solving the equation to find the value of x -

[tex]x^{2} =2x\\x^{2} -2x=0\\[/tex]

x (x - 2) = 0

x = 0          or           x - 2 = 0

Test case 1 : for [tex]x = 2[/tex]

[tex]x^{2} =2x\\2^{2} =2 (2)\\4 =4[/tex]

LHS = RHS

Test case 2 : for [tex]x =0[/tex]

[tex]x^{2} =2x[/tex]

[tex]0^{2} = 2(0)[/tex]

[tex]0 = 0[/tex]

LHS = RHS

Hence, the equation [tex]x^{2} = 2x[/tex] is a true equation for [tex]x=0[/tex] and [tex]x=2[/tex]

We can use the similar approach in the equation -

                                     [tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex]

to find the value of [tex]x[/tex] for which the equation is true.

-8(x+5) = -3x-7+x-3

-8x-40=-2x-10

-8x+2x = -10+40

-6x = 30

x=-5

Hence, for x = -5 the equation [tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex] is true equation.

Question 17: There were 900 students initially infected by the flu. After
medicine was distributed, the number of sick students was cut in half
every week. How many will still be sick after 4 weeks?

Answers

Answer:

56 will be sick after 4 weeks.

Step-by-step explanation:

900 / 2 = 450 (Week 1)

450 / 2 = 225 (Week 2)

225 / 2 = 112.5 (Week 3)

112.5 / 2 = 56.25 (Week 4)

(Rounding to a whole number since there can't be a quarter of a child)

Answer:

56.25 students would still be sick after 4 weeks

The roof of the building shown below has a span of 48 feet. The rafters upon which the roof is laid are 30 feet long, including a 4 foot overhung. a. Knowing that the pitch of a roof is the ratio of the rise to the run, find the pitch of this roof. B. If the entire roofline measures 100 feet from end to end, find the total area of the roof. c. Find the percent of the roof used for the overhang

Answers

Solution :

Given :

Span of the roof = 48 feet

Length of the rafter = 30 feet (including the 4 feet overhung)

So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.

Therefore, the horizontal span per rafter is

[tex]$=\frac{48}{2}$[/tex]

= 24 feet

a). So the rise of the roof is [tex]$= \sqrt{(26)^2-(24)^2}$[/tex]  

                                         = 10 feet

b). Pinch of the roof is [tex]$=\frac{\text{rise}}{\text{run}}$[/tex]

                                     [tex]$=\frac{10}{24}$[/tex]

                                     [tex]$=\frac{5}{12}$[/tex]

c). The percent of the roof used as overhung is

     [tex]$=\frac{4+4}{60}\times 100$[/tex]

     [tex]$=\frac{80}{6}$[/tex]

       = 13.33 %

Answers

Answer:

The reflection will be on the first quadrant

Step-by-step explanation:

Here, we want to reflect the given point over the y-axis

By reflecting over the y-axis, we simply have to negate the x-coordinate value

So after the reflection, the point (-8,5) becomes (8,5)

(8,5) is a point on the first quadrant

So we have the position after the reflection on the first quadrant
