please help, numbers 14 & 16 only. thank you so much, I’ll mark brainliest.

Answer:

the first option

Step-by-step explanation:

to find a set of ordered pairs that are not a function you would want to look at all the x-intercepts and find the order that has more than one number repeating itself like 1 in the first option

(4x+7)(2x+5) Like this???

4x+7=2x+5 or like this?!!?!

Answer:

y = 140

Step-by-step explanation:

Given y varies directly with [tex]\sqrt{x}[/tex] then the equation relating them is

y = k[tex]\sqrt{x}[/tex] ← k is the constant of variation

To find k use the condition y = 42 when x = 9 , then

42 = k [tex]\sqrt{9}[/tex] = 3k ( divide both sides by 3 )

14 = k

y = 14[tex]\sqrt{x}[/tex] ← equation of variation

When x = 100 , then

y = 14 × [tex]\sqrt{100}[/tex] = 14 × 10 = 140

Answer:

Slope: -2

Step-by-step explanation:

(2, -10) and (-4, 2).

m = y1 - y2 / x1 - x2

m = -10-2/2-(-4)

m = -12/6

m = -2

Answer:

They look the same

Answer:

100

Step-by-step explanation:

The perfect square integers are:

1^2 , 2^2, 3^2, 4^2, 5^2, 6^2, ...

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, ...

We note from the list above that the smallest integer

whose square root is an integer of two digits is 100.

The next smallest perfect square is 81, and its square

root is 9, which is a one digit integer.

 9/36 simplified to lowest terms is 1/4.

Answer

t = -4

Step-by-step explanation:

First you subtract 9 from both sides. You get 12 on the right. Then you divide both sides by -3. You get -4.

Answer: t<=10

Step-by-step explanation:

-3t+9>=-21

-3t>=-30

3t<=30

t<=10

Answer:

56 my boi

Step-by-step explanation:

35 + 21 = 7(5 + 3)

56 = 7(8)

56 = 56

Answer : The slope is 2.5

Answer:

-1/3

Step-by-step explanation:

its rise overrun.

you rise two and run 6, and its a negative slope

when you simplify, it's then -1/3

Answer:

The length of the longer base is a. 33 in

Step-by-step explanation:

This is true because if the longer base is 3 more inches than 2 times the amount of the shorter base, all you have to do is 15 x 2 + 3 = 33 in

Hope it helps! =)

Answer: A or 33inches

Step-by-step explanation

First write expressions for the longer base

Longer base: 3 + 2x

Shorter base: x

then solve

If x = 15 then..

3 + 2x

3 + 2(15)

3 + 30

33

THE LONGER BASE IS 33 INCHES

THANKS SA POINTS

[tex]stay \: safe[/tex]

Answer:

[tex]Their \: sum \: is -334[/tex]

[tex]x + x+1 + x+2 + x+3 = -334[/tex]

[tex]4x + 6 = -334[/tex]

[tex]4x = -340[/tex]

[tex]x = -85 [/tex]

Step-by-step explanation:

[tex]Thanks!!!!![/tex]

Answer:

the first number is x (x ∈ Z)

=> four consecutive integers are x, x + 1, x +2, x + 3

because the sum of them = -334, we have:

x + (x + 1) + (x + 2) + (x + 3) = -334

⇔ 4x + 6 = -334

⇔ 4x = -334 - 6 = -340

⇔ x = -340/4

⇔ x = -85

=> 4 consecutive integers are -85; -84; -83; -82

Step-by-step explanation:

Answer:

We can easily figure out how fast the boat is moving per hour.

35 km / 7 hours = 5 km/h

We now know that we are moving at a rate of 5 kilometers every 1 hour. We can now take our 5 km/h and multiply it by 3 hours to get our answer

5 km/h x 3 = 15 kilometers

Given points:

Find the slope:

Point - slope form:

Convert into slope- intercept form:

Convert into standard form:

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

let's find slope (m) :

Plugging value of x and y from point (0 , 1) and slope (m) = -3, in general equation of line we will get the value of y - intercept (c)

that is :

y intercept (c) = 1, now let's plug the value of slope(m) and y - intercept (c) in general equation of line to get the required equation of line which passes from given two points.

Answer:

Step-by-step explanation:

From the table showing in the diagram, Let's pick the data in the first row:

Time = 3 hours

Money earned = $45

The amount of money Carl earns per hour is calculated as:

3 hours = $45

1 hour = ?

Cross Multiply

1 hour x $45 / 3 hours

= $15

Let's confirm our answer using the data in the last column

Time = 10 hours

Money earned = $150

The amount of money Carl earns per hour is calculated as:

10 hours = $150

1 hour = ?

Cross Multiply

1 hour x $150 / 10 hours

= $15

Therefore, the amount of money Carl earns per hour is $15

Answer:

he earns 15 dollars per hour. 45/3 is 15
