Henry showed all the steps he took to solve the equation.

4 (negative one-half x + 7) + 5 x = 15

Step
Simplified Expression
1
-Negative 2 x + 28 + 5 x = 15
2
3 x + 28 = 15
3
3 x = 15
4
x = 5

Sammy tried to verify the solution by substituting x = 5 back into the original equation. It did not result in a true statement. Which explains why Henry’s solution is incorrect?
Step 1 is wrong because the distributive property of equality was used incorrectly.
Step 2 is wrong because the addition property of equality was used incorrectly.
Step 3 is wrong because the subtraction property of equality was used incorrectly.
Step 4 is wrong because the division property was used incorrectly.

Answer:

450 N.

Step-by-step explanation:

By Hooke's law

Force = k * displacement so

150 = k * 1

So k = 150 and the equation is

F = 150 d

So when d = 3

F = 150 * 3 = 450.

Step-by-step explanation:

Answer: 4/3

First, rewrite in slope-intercept form:

-3y=-5-4x

3y=5+4x

y=5/3+4/3x

y=4/3x+5/3

And so we can see that 4/3 is the slope of the equation.

Answer:

Step-by-step explanation:

remember that the surface area is

S=2lw+2lh+2hw

S=2(15*20)+2(15*8)+2(8*20)=600+240+320=1160 cm^2

The surface area of the cuboid is 1160 square cm whose dimensions are

l= 20cm, w= 8 cm and h = 15 cm.

Given:

Length = 20 cm

width = 8 cm

Height = 15 cm

So, the formula for Surface area of Cuboid is

= 2(lw+ wh + lh)

Substituting the values l= 20cm, w= 8 cm and h = 15 cm into the formula as

= 2(lw+ wh + lh)

= 2 (20 x 15 + 8 x 15 + 8 x 20)

= 2 (300 + 120 + 160)

= 2 (580)

= 1160 square cm

[tex]2\frac{7}{10}[/tex]

Step-by-step explanation:

[tex]\frac{3}{2}+\frac{6}{5}[/tex]

[tex]=\frac{15}{10} +\frac{12}{10}[/tex]

[tex]=\frac{27}{10} =2\frac{7}{10}[/tex]

The lenght of the diameter of the circle P is 6.4

To solve this particular sum we need to know the concept of Distance formula . Distance formula is nothing but calculating the lenght of a line segment which has two end points .There are various types of distance formulas which we can use to calculate various things.

The different types of distance formulas are :

The distance formula is : √{(x₂-x₁)² + (y₂-y₁)²}

Using this formula we will be able to find out the lenght of diameter of the circle P where endpoints are given as (-7,8) and (-11,-13)

(x₁,y₁) = (-7,8)

(x₂,y₂) = (-11,-13)

Substituting the values of  x₁,y₁,x₂,y₂ in the formula we will get

∴ √{(-11+7)²+(-13+8)²}

= √{(-4)²+ (-5)²}

= √{16+25}

= √41

= 6.403

= 6.4 (rounded of to the nearest tenth)

Answer:

Choice C

Step-by-step explanation:

First when we are looking for a system of equations that has no solution we are looking for two lines that won't intersect and the only lines that would never intersect are parallel lines.

Ok so what we are looking for is an equation with the same slope but different y-intercept. A parallel line should go at the same rate like the other line but shouldn't start at the same point.

[tex]y=\frac{1}{3}x-7[/tex]

Analysing Choice A:

[tex]y=3x+2[/tex]

We just said that the slope has to be the same so this one can't be it.

Analysing Choice B:

For this one we have to put it in slope-intercept-form.

[tex]3y-x=-21\\3y=x-21\\y=\frac{1}{3}-7[/tex]

So we see that the slope is the same for this one and and the y-intercept is also the same which is NOT what we need so on tho the next one.

Analysing Choice C:

For this one we also have to put it in slope-intercept-form.

[tex]y-2=\frac{1}{3}(x+1)\\y-2=\frac{1}{3}x+1\frac{1}{3}\\y=\frac{1}{3}x-\frac{2}{3}[/tex]

We see that the slope are the same and the y-intercept are different so this is the one we are looking for.

Sorry but for the sake of time I won't analyze choice D.

Explanation:

Start at x = 3 on the x axis. Move up until you reach g(x), then move to the left to hit the y axis. You should arrive at y = 3.

That y value is the input to the f(x) function.

Plugging x = 3 into the f(x) function has us draw a vertical line down to f(x) and then go horizontally until we reach y = -2.
