Answer:

k<10

Step-by-step explanation:

Based on your image, I will assume u meant: [tex]|2x+4| \leq 6[/tex]

This means that x will have two solution sets, due to the absolute value.

[tex]-5\leq x\leq 1[/tex]

Answer:

Distributive property

Step-by-step explanation:

Distributive property: Multiplying the sum of two+ addends by a number will be equal as multiplying each addend by itself by the number and then adding them together.

Answer:

(a) [tex]Unit = \frac{1}{4}/8[/tex]

Step-by-step explanation:

Given

[tex]Time = \frac{1}{4}[/tex]

[tex]Lap = 8[/tex]

Required

Determine the time in each lap

The unit time in each lap is calculated by dividing the total time by the number of laps; i.e.;

[tex]Unit = \frac{Time}{Lap}[/tex]

Substitute values for Time and Lap

[tex]Unit = \frac{1}{4}/8[/tex]

Answer:

y-intercept=5

x-intercept=-2

Step-by-step explanation:

To find the y intercept, plug in 0 for x. So you get 10(0)-4y=-20. Simplify, and clear out the negatives on both sides because they cancel each other out. 4y=20 would be your final equation. y=5.

To find the x intercept, you plug in 0 for y this time. The equation is 10x-4(0)=-20. Simplify to get, 10x=-20. You cannot remove the negative because there isn't a negative sign on the 10x. -20/10 is -2.

Answer:

15

Step-by-step explanation:

The ratio of trucks to cars is 6x/10. And in the problem it says that there are 25 cars. So, 10x = 25, x = 5/2. Then, 6x = 15

Answer: The answer is,

$5,110

Option (B)

The tax of a single person that earns $33,200 is $5110

The earnings (E) is given as:

[tex]E = \$33,200[/tex]

From the tax table, the equation to calculate the tax of a single person within the income range $28400 to $68,799.99 is:

[tex]Tax =0.25E - 3190[/tex]

So, we have:

[tex]Tax =0.25 \times 33200 - 3190[/tex]

[tex]Tax =8300 - 3190[/tex]

Evaluate the like terms

[tex]Tax =5110[/tex]

Hence, the tax of a single person that earns $33,200 is $5110

Answer:

x = 2, y = -1

Step-by-step explanation:

We have a solution system, x = -6y - 4 and 6x - 12y = 24.

Now, since are not only asked to use the substitution method, but at the same time know the value of x, let's plug the first system into the second.

x = -6y - 4

6(-6y - 4) - 12y = 24

-36y - 24 - 12y = 24

-48y - 24 = 24

Add 24 to both sides :

-48y = 48

Divide -48 by both sides :

y = -1

Now that we have y, we can replace it into the second system again to get x.

6x - 12(-1) = 24

6x + 12 = 24

Solve for x by first getting rid of 12 from both sides :

6x = 12

Divide 6 by both sides :

x = 2

Therefore, x = 2 and y = -1

Answer:

y=-2+4

Step-by-step explanation:

we know the y intercept is four, so we can plug that into y=mx+b

so far we know y=mx+4

and the equation for finding slope is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

so let's find two points on the graph

let's make it easy on ourselves and use the points laid out for us

(0,4) and (2,0)

[tex]\frac{0-4}{2-0}[/tex]

solving that would come out to be [tex]\frac{-4}{2}[/tex]

simplified, that would be -2

now that we know the slope, we can put them into slope-intercept form

y=-2+4

Step-by-step explanation:

-8x+5 > 21

Minus 5 from both sides

-8x > 16

Then divide 8 from both sides (also I am pretty sure the sign would change because you are dividing by a negative number)

x < -2

So the answer is x is less than or equal to -2

or C
