Answer:

Step-by-step explanation:

The pair of number that makes the expression [tex]a^x = ax[/tex] true are 2 and 2 as shown:

where a = 2 and x =2

2² = 2*2

2² = 4

and:

2*2 = 4

Hence 2²  = 2(2) = 4 making the expression [tex]a^x = ax[/tex] true for both pair of numbers

Also the number pair 1 and 2 makes the expression correct as shown:

[tex]2^1 = 2(1)\\2 = 2 (true)[/tex]

Answer:

72

Step-by-step explanation:

-2 x -4 = 8

8 x 9 = 72

Hope this helps! Please mark Brainliest!

Answer:

72 = Positive

Step-by-step explanation:

The property we use,

→ Associative property

Now the product will be,

→ (-2 × -4) × 9

→ 8 × 9 = 72

→ -2 × (-4 × 9)

→ -2 × (-36) = 72

Then the required sign is,

→ Positive (+ve)

Hence, the product is 72.

Answer:

y= -4/5x+33/5

Step-by-step explanation:

for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.

x1=7 and y1=1

x2=-3 and y2=9

now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5

now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.

to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).

1= -4/5 x 7+b. b= 33/5

Answer:

back where he started

Step-by-step explanation:

First he went up 30 feet.

Then he went -30 feet.

Meaning that he went up the went back down.

Answer:

(3x−y)(x+7y)

Step-by-step explanation:

Factor (2x+3y)^2−(x−4y)^2

3x^2+20xy−7y^2

=(3x−y)(x+7y)

Answer:

(3x - y)(x + 7y)

Step-by-step explanation:

Given

(2x + 3y)² - (x - 4y)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = 2x + 3y and b = x - 4y , then

(2x + 3y + x - 4y)(2x + 3y - (x - 4y))

= (3x - y)(2x + 3y - x + 4y) = (3x - y)(x + 7y)

Thus

(2x + 3y)² - (x - 4y)² = (3x - y)(x + 7y) ← in factored form

Answer:

5x-11

Step-by-step explanation:

This is the word problem as an expression

5x-55 represents the mathematical expression for the given statement.

Expressions in maths are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is a statement, the product of five and a number, decreased by eleven,

Let the number be x, converting the given statement, into a mathematical expression, we get

5(x-11)

= 5x-55

Hence, 5x-55 represents the mathematical expression for the given statement.

Answer: Is it not 6km an hour?

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Jacinda = 16 baskets

Greta = 4 baskets

The number of baskets Jacinda made is how many times more than the number of baskets Greta made?

To obtain this :

Number of baskets Jacinda made / Number of baskets Greta made

If Jacinda's basket = J ; Greta's basket = G

J / G

16 / 4 = 4

Hence, Number of basket Jacinda made is 4 times more than that made by Greta

Answer:

He should sell them he would be rich.

Step-by-step explanation:

Answer:

He made $581 if he worked 44 1/2 hours last week

Step-by-step explanation:

Let us solve the question

∵ Henry makes $12.50 per hour for the first 40 hours

∵ For each additional hour, he makes $18 per hour

→ We need to find how much he made if he worked 44 1/2 hours

→ At first, find his earning for the first 40 hours

∵ His earning in the first 40 hours = 40 × 12.50

∴  His earning in the first 40 hours = $500

→ Find how many hours he worked after the first 40 hours

∵ 44 1/2 - 40 = 4 1/2 hours

∴ He worked 4 1/2 hours over the first 40 hours

→ Find his earning from them

∵ His earning in 4 1/2 hours = 4 1/2 × 18

∴ His earning in 4 1/2 hours = $81

→ Now add the two amounts to find his total earning

∵ His total earning = 500 + 81

∴ His total earning = $581

∴ He made $581 if he worked 44 1/2 hours last week

Answer:

Here you go :)

Hey, don't sweat it, this is relatively simple.

0 = $0

1 = $400

2 = $800

3 = $1400

Just keep adding my friend

Answer:

x=m-z

Step-by-step explanation:

The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z
