Answer:

[tex]\boxed {x < -4}[/tex] (Choice D)

Step-by-step explanation:

You first need to solve the following inequality in order to get the actual answer and find the actual graph:

[tex]1 + 2x < -7[/tex]

-Subtract [tex]1[/tex] to both sides:

[tex]1 - 1 + 2x < -7 - 1[/tex]

[tex]2x < -8[/tex]

-Divide both sides by [tex]2[/tex]:

[tex]\frac{2x}{2} < \frac{-8}{2}[/tex]

[tex]\boxed {x < -4}[/tex]

The number line graphed:

Given:

There exist a proportional relationship between x and y.

To find:

The equation which represents a proportional relationship between x and y.

Solution:

If there exist a proportional relationship between x and y, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

where, k is constant of proportionality.

We know that, proportional relationship passes through the origin because (0,0) satisfy [tex]y=kx[/tex].

For x=0, check which equation has y=0.

In option A, [tex]y=-3(0)-2=-2[/tex].

In option B, [tex]y=9[/tex].

In option C, [tex]y=4(0)=0[/tex].

In option D, [tex]y=3(0)+1=1[/tex]

Only in option C, we have a equation of the form [tex]y=kx[/tex] with 4 as constant of proportionality and it passes through (0,0).

Therefore, the correct option is C.

Answer:

9 AM

Step-by-step explanation:

Let t = traveling time of the 1st train, when the 2nd train catches up

Then

(t-3) = traveling time of the the 2nd train.

When this occurs, both trains will have traveled the same distance;

Write a distance equation: Dist. = speed * time

100(t-3) = 80t

100t - 300 = 8t

100t- 80t = +300

20t = 300

t = 300/20

t = 15 hrs.

Time = 6 PM + 15 hrs. = 9 AM the next day

Step-by-step explanation:

Ryan earned $233.40 from the tips. Option D is correct

Ryan works at the car wash making $5.30 per hour plus tips.
Last week Ryan worked 32 hours and earned $403
How much in tips did Ryan make last week?

In mathematics, it deals with numbers of operations according to the statements.

Let the tip Ryan get be x,
Ryan earned $5.30 per hour.
Ryan earned $403 for 32 hours of the working,
Ryan worked 32 hours so,
Ryan earned = 32 * 5.30
                      = 196.4
Total tips that Ryan earned = total earning - Ryan earned
                                               = $403 - $196.4
                                               = $233.40

Thus, Ryan earned $233.40 from the tips. Option D is correct

Answer:

Step-by-step explanation:

given the amount $8.162

if we are to round this amount to the nearest hundredth, we would have

$8.16

this is because will have already consider the last value in the given digit and this value is not up to 5  hence we are not able to round the number next to it up, but we have to retain its current value of 6.

therefore the value is

$8.16

Answer:

$8.16

Step-by-step explanation:

Let's solve your inequality step-by-step.

122<−2(8x+3)

Step 1: Simplify both sides of the inequality.

122<−16x−6

Step 2: Flip the equation.

−16x−6>122

Step 3: Add 6 to both sides.

−16x−6+6>122+6

−16x>128

Step 4: Divide both sides by -16.

−16x /−16 > 128 /−16

x<−8

Answer:

[tex]y-1/2=2(x+7/2)^2[/tex]

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y-k=a(x-h)^2[/tex]

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

The given function is:

[tex]y=(x+3)^2+(x+4)^2[/tex]

Expanding the squares:

[tex]y=x^2+6x+9+x^2+8x+16[/tex]

Simplifying:

[tex]y=2x^2+14x+25[/tex]

Factoring 2 from the first two terms:

[tex]y=2(x^2+7x)+25[/tex]

The expression in parentheses must be completed to form the square of a binomial:

[tex]y=2(x^2+7x+49/4-49/4)+25[/tex]

Isolating the square of the binomial:

[tex]y=2(x^2+7x+49/4)-49/2+25[/tex]

Operating and Factoring:

[tex]y=2(x+7/2)^2+1/2[/tex]

Rearranging:

[tex]\boxed{y-1/2=2(x+7/2)^2}[/tex]

Comparing with the vertex form:

a=2, h=-7/2, k=1/2

Step-by-step explanation:

[tex] -3x + 4=6x-5\\\\6x+3x=4+5\\\\9x=9\\\\x=\sf{\dfrac{9}{9}}\\\\X=1[/tex]
