4. What is the domain of the relation shown in the table?
1 point
A {-23, -14, -8, 1, 10}
B {(-5, -23), (-2,-14), (0,-8), (3,1), (6,10)}
C {-23, -14, -8, -5, -2, 0, 1, 3, 6, 10}
D {-5, 2, 0, 3, 6}

Answer:

y=-3x+27

Step-by-step explanation:

If its parallel that means the -3x will stay the same. After you plug (9,0) in as x and y into the equation. So now you have 0=-3(9)+b  then solve for b and you get your equation.

Slope = -3

Y intercept = 27

=============================================================

Explanation:

The given line is in the form y = mx+b. Here we have m = -3 as the slope.

Any line parallel to this also has the same slope. Parallel lines have equal slopes but different y intercepts.

The parallel line has slope m = -3.

We want the parallel line to go through (x,y) = (9,0). So x = 9 and y = 0 pair up.

Plug m = -3, x = 9 and y = 0 into the equation below. Solve for b.

y = mx+b

0 = -3(9) + b

0 = -27 + b

27 = b

b = 27

You could also use point slope form

y - y1 = m(x - x1)

y - 0 = -3(x - 9)

y  = -3(x-9)

y = -3x - 3(-9)

y = -3x + 27

and we'd get the same result.

Answer:

2

Step-by-step explanation:

-2^2=4

4*1/2=2

==============================================

Explanation:

If f(x) is an even function, then,

f(-x) = f(x)

for all x in the domain

Based on that, we can say f(-3) = f(3)

So,

y = -2*f(3) - 3*f(-3)

y = -2*f(3) - 3*f(3)

y = -2*(-5) - 3*(-5)

y = 10 + 15

y = 25

Answer:

No

Step-by-step explanation: By dividing 12/98 you would get a decimal(0.12244897959) by this not being a whole number it can not be a perfect square.

Answer:

Wow, my name is maddie and i have a Nintendo switch. Lolll ok but the answer is:

$192!

Step-by-step explanation:

60 percent of 320 is the same as 60 per hundred of 320. We can therefore make the following equation:

60/100 = X/320

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 320, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

60/100 = X/320

X/320 = 60/100

X*320/320 = 60*320/100

X = 19200/100

X = 192

The work above shows the long way to explain how to calculate 60 percent of 320 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 60 percent of 320?", Y is 320 and P is 60:

(320 * 60)/100 = 192

And once again you see that the answer is 192.

Answer:

1. B

2. D

Step-by-step explanation:

1. Lon's cost would be the $12 per basket times how many baskets he sells, in this case b plus the cost of the table. Lon's expression is 12b + 75

2. He needs a profit and the only way he could make that profit is if he sells more than 12.

20b > 12b + 75

20 (12) > 12 (12) + 75

240 > 140 + 75

240 > 215

Answer:

The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles

Step-by-step explanation:

The given parameters are;

The distance between the two cyclist when they begin biking away from each other = 7 miles

The first cyclist's speed = 12 miles per hour

The second cyclist's speed = 12 + b miles per hour

Therefore, we have;

The equation for distance covered, d = Speed × Time

The distance covered by the second cyclist in 45 minutes, [tex]d_{45 \ minutes}[/tex] is given as follows;

45 minutes = 3/4 hour

[tex]d_{45 \ minutes}[/tex]  = (12 + b) × 3/4 = (3/4·b + 9) miles

The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.

Answer:

The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles

Step-by-step explanation:

The given parameters are;The distance between the two cyclist when they begin biking away from each other = 7 milesThe first cyclist's speed = 12 miles per hourThe second cyclist's speed = 12 + b miles per hourTherefore, we have;The equation for distance covered, d = Speed × TimeThe distance covered by the second cyclist in 45 minutes,  is given as follows;45 minutes = 3/4 hour  = (12 + b) × 3/4 = (3/4·b + 9) milesThe distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.

Answer:

d. -4/5

Step-by-step explanation:

When using the equation m = y2 - y1 / x2 - x1, we get m = 5-1 / -3-2.

Simplified: m = 4/-5.

The negative can be placed on the numerator or denominator, it doesn't make a difference.

Answer:

A = 3.6

Step-by-step explanation:

5.4 = a - (-1.8)

5.4 = a + 1.8

subtract 1.8 from both sides

3.6 = a

Hope this helps. Pls give brainliest.

Answer:

a = 3.6

Step-by-step explanation:

5.4=a−(−1.8)

Step 1: Simplify both sides of the equation.

5.4=a+1.8

Step 2: Flip the equation.

a+1.8=5.4

Step 3: Subtract 1.8 from both sides.

a+1.8−1.8=5.4−1.8

a=3.6

Answer:

8

Step-by-step explanation:

f(1) is another notation for x = 1

so we’ll plug in 1 for x

f(1) = 7((1) -1) +8

f(1) = 7(0) +8

f(1) = 0 +8

f(1) = 8

Answer:

5 months, no heather will have 20x + 110

Answer:

x= 1.3

Step-by-step explanation:

You have to plug in 7 so it will look like:

f(x) = -2x² + 4

7(x) = -2x² +4

now what you have to do is multiply 7 by x which will get you

7x = -2x² + 4

now because you have that you want to multiply -2 twice because you have that ²

7x = 4x +4

now you want to move the 4x and you can do that by doing the inverse operation and in this case since its a positive 4 you may want to subtract 4x from 4x and 7x

3x=4

now you want to divide 4 from 3  and you get 1.333333333333333

Answer:

14.9m

Step-by-step explanation:

Say that the centre point is O, the letter to make it easier to explain.

The angle DOB is equal to the angle AOE because they're vertically opposite

We also know that angle DOB = 52 + 90 = 142, so angle AOE = 142

To work out the length of the segment, it would be to find the circumference and multiply with the angle over 360:

πd × [tex]\frac{142}{360}[/tex]

(where d = diameter)

we know that the diameter is 12m so we can input this:

12π × [tex]\frac{142}{360}[/tex] = 14.87020523

to the nearest tenth = 14.9m

[tex]\log \:_2\left(3\right)+\log \:_2\left(15\right)-\log \:_2\left(9\right)=\log \:_2\left(5\right)=2.32[/tex]    

Step-by-step explanation:

Given the expression

[tex]\log _2\left(3\right)+\log _2\left(15\right)-\log _2\left(9\right)[/tex]

[tex]\mathrm{Apply\:log\:rule}:\quad \log _c\left(a\right)+\log _c\left(b\right)=\log _c\left(ab\right)[/tex]

[tex]\log _2\left(3\right)+\log _2\left(15\right)=\log _2\left(3\cdot \:15\right)[/tex]

[tex]=\log _2\left(3\cdot \:15\right)-\log _2\left(9\right)[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:3\cdot \:15=45[/tex]

[tex]=\log _2\left(45\right)-\log _2\left(9\right)[/tex]

[tex]\mathrm{Apply\:log\:rule}:\quad \log _c\left(a\right)-\log _c\left(b\right)=\log _c\left(\frac{a}{b}\right)[/tex]
