Given f(x) = 5x – 3, find f(-3) )

Answer:

D, neither

Step-by-step explanation:

If you want to solve this through elimination, just substitute the given points in each choice. (a,b) → (x,y)

In a coordinate the first number is the x value, and the second is the y.

All you have to do is substitute the indicated values given in the coordinate into the point slope equation, and determine whether or not the equation is true. If the equation is true (for example 1 = 1) the order pair IS a solution. If the equation is false (for example 1 = 2), than the ordered pair IS NOT a solution.

If you want to look at this linear equation solving for the quantity y, then use slope intercept.

Choice 1 is incorrect because (5,4) →

y - 4 = 7(x - 6) → (4) - 4 = 7((5) - 6) →

0 = 7(-1) → 0 = -7 (0 is never equal to -7) ; contradictory

Choice 2 is incorrect because (6,5) →

y - 4 = 7(x - 6) → (5) - 4 = 7((6) - 6) →

1 = 7(0) → 1 = 0 (1 is never equal to 0) ; contradictory

Therefore Choice 3 must be incorrect as well because neither of these two pairs are solutions, so combining two pairs that do not satisfy the equation does not make it any more true.

Since Choice 4 is the remaining choice, it must be the correct answer.

The points that fit on this line are given by the slope intercept equation: y = 7x - 3.

To convert point slope form to slope intercept form, first distribute everything in the parenthesis. Then remove all the terms besides y from the left side of the equation to the right:

y - 4 = 7(x - 6) → y - 4 = 7(x) + 7(-6) →

y - 4 = 7x - 42 → y - 4 + 4 = 7x - 42 + 4 →

y = 7x - 38.

Just substitute the x or y value into the equation, and find the corresponding y or x variable that fits the line.

Answer:

the length of shorter side is 9 inches.

longer side is enlarged 3times

so shorter side will also be enlarged 3 times.

Answer: $14.85

Step-by-step explanation:

Ww can solve the question using direct proportion with the formula y = kx

where y = annual salary

x = monthly policy cost.

k = constant of proportionality

Since y = kx

38500 = 11.55k

k = 38500 / 11.55

k = $3333.33

When Randy has an annual salary of $49,500, the amount Randy expect to pay for his policy will be:

y = kx

49500 = 3333.33x

x = 49500 / 3333.33

x = 14.85

The amount that Randy expect to pay for his policy will be $14.85

Answer:

2.75 and -2.75

Step-by-step explanation:

The absolute value of 2.75 is 2.75 and the absolute value of -2.75 is 2.75

The answer is 6.

Absolute value works like this:

If you have just a number inside the bars, then it's positive. If the negative sign is inside the bars, it's still positive. If the negative sign is outside the bars, regardless of what's inside the bars, then it's negative.

Basically, you are adding, because absolute values are positive, unless you have a minus sign outside the absolute value, so 6+5=11.

What you do is this:

y = |x - 5|

y = x + 5

y = 11 + 5

y = 6

Answer:

The solution is  x = 9, y = -1.

Step-by-step explanation:

x + y = 8

x -  y = 10       Adding to eliminate y:

2x + 0 = 18

x = 9               Substituting x = 9 into the first equation:

9 + y = 8

y = 8 - 9

y = -1..

Answer:

x= 33

y= 106

Step-by-step explanation:

4x-58=74

+58 +58

4x=132

4x/4=132/4

x=33

If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°.

Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.

It is known that the If two parallel lines intersect another two parallel lines then all corresponding angles will be the same.

Therefore, 74 = 4x - 58

4x = 132

x = 33.

Since 74° and the adjacent angle of y° are made by two parallel lines on the same line thus both will also same.

The adjacent angle of y = 74°

Since,  adjacent angle + y = 180°

y = 180 - 74 = 106°.

Hence "If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°".

Answer:

Step-by-step explanation:

since its a square, the outsides are 6x6.

since the area of A is two times of B, we just have to guess the dimensions of the shorter side. The longer side is always going to be 6, it doesn't get cut there. so A is 6x4=24 and B is 6x2=12. 24 is twice 12. 2:1 ratio

Answer:

C

Step-by-step explanation:

We have the compound inequality:

[tex]5x+7\leq-3\text{ or } 3x-4\geq11[/tex]

We will solve each inequality individually and then combine them at the end.

For the first inequality, we have:

[tex]5x+7\leq-3[/tex]

Subtract 7 from both sides:

[tex]5x\leq-10[/tex]

Divide both sides by 5:

[tex]x\leq-2[/tex]

For the second inequality, we have:

[tex]3x-4\geq11[/tex]

Add 4 to both sides:

[tex]3x\geq15[/tex]

Divide both sides by 3:

[tex]x\geq5[/tex]

Since our original inequality was an “OR,” our solution set is also an “OR.”

Hence, our solution is:

[tex]x\leq-2\text{ or } x\geq5[/tex]

Thus, our answer is C.
