Step-by-step explanation:

☆9x - 15 is congruent to 7x + 5, meaning they equal the same. This is because they are vertical to each other

☆The equation would be a 9x - 15 = 7x + 5.

☆Let's solve it!

[tex] \: \: \: \: \: \: \: \: \: 9x - 15 = 7x + 5 \\ \frac{ - 7x \: \: \: \: \: \: \: = - 7x}{2x - 15 = 5} \\ \frac{ \: \: \: \: \: \: \: \: \: \: + 15 = + 15}{ \frac{2x}{2} = \frac{20}{2} } \\ \\ x = 10[/tex]

-------

☆2x + 15 and x are complementary angles, meaning they equal 90ndegrees together. This is because they lie on a right angle.

☆The equation would be: 2x + 15 + x = 90.

☆Let's solve it!

[tex]2x + 15 + x = 90 \\ 3x + 15 = 90 \\ \frac{ \: \: \: \: \: \: \: \: \: - 15 = - 15}{ \frac{3x}{3} = \frac{75}{3} } \\ \\ x = 25[/tex]

Answer:

  y = -1/2x -2

Step-by-step explanation:

The given line has slope 2, so the perpendicular line will have slope -1/2, the negative reciprocal of the given slope.

The y-intercept is given as -2, so the line's equation in slope-intercept form is ...

  y = mx +b . . . . line with slope m and y-intercept b

  y = -1/2x -2

Answer:

He must score an 86 or more on his third test.

Step-by-step explanation:

An average is calculated by the sum of the numbers divided by the total number (#) of numbers (if that makes sense). Knowing this, we can write an algebraic equation in order to find the answer. Let x equal the unknown number.

John's previous test scores and this test score now must be at least an average of 90 or more. Therefore, the equation would be [tex]\frac{86+98+x}{3} \geq 90[/tex]. Isolate x to find the answer:

[tex]\frac{86+98+x}{3}\geq 90\\ \frac{184+x}{3} \geq 90\\184 + x \geq 270\\x \geq 86[/tex]

Therefore, he needs to get at least a 86 or higher.

The correct answer is,

[tex] \frac{1}{64} [/tex]

Answer:

1/64

Step-by-step explanation:

when exponents are separated by parentheses, multiply them

so (2³)^-2 = 2^-6

whenever an exponent is negative, change into fraction form with one as the numerator and the other term goes into the denominator and the exponent now becomes positive

2^-6 = [tex]\frac{1}{2^6}[/tex] = [tex]\frac{1}{64}[/tex]

Answer:

if all the pots have an even amount then you should be left with 5 flowers left

Step-by-step explanation:

28+37= 65 there are 6 pots so take 5 away and each pot gets 10

now each pot has an even amount and you are left with 5

Answer:

the zeros of the function are those that result, when plugged into the equation, in zero; the zeros are -3, 1, and 1/2

Step-by-step explanation:

all possible factors:

±3/2,  ±1/2,  ±3,  ±1

2x³ + 3x² - 8x + 3

let '2' = p and let '3' = q

factors of 'p' are 1 and 2

let '3' = q

factors of 'q' are 1 and 3

possible factors are q/p

Step-by-step explanation:

Hi there :)

So since they initially drank 50 gallons, half of that is 25 gallons. 50+25= 75, therefore they drank 75 gallons.

Jada has 12 library books and 1/3 of that is 4, because 12 divided by 3 is 4, so 12-4=8. That means Han checked out only 8 books.

Good luck with the rest of your assignment, have a good day/night!!

Step-by-step explanation:

Answer:

The graph of the equation y = 20x+25 is attached below.

Please check the attached graph.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case, we are given that the cost y (in dollars) of a gym membership for x months is:

[tex]y=20x+25[/tex]

comparing with the slope-intercept form of the line equation

Here:

The slope of the equation is: m = 20

The y-intercept is: b = 25

The graph of the equation y = 20x+25 is also attached below.

From the graph, it is clear that the graph of the line crosses the y-axis at y = 25.

Thus, the point (0, 25) represents the y-intercept of the function.

Please check the attached graph.

Answer:

x<331/5

Step-by-step explanation:

Step 1: Subtract 351 from both sides.

−5x+351−351>20−351

−5x>−331

Step 2: Divide both sides by -5.

−5x
