Answer:

4)

Step-by-step explanation:

I think that you meant slope of 9/4. Number 4 would be correct because slope intercept form would be y=mx+b, where m is the slope and b is y intercept. Since b=0, you don't have to add anything, so it would just be y=9/4x

Answer:

4) [tex]y=\frac{9}{4}x[/tex]

Step-by-step explanation:

This is a linear equation in slope-intercept form:

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

where m is the slope and b is the y-intercept.

1) [tex]y=\frac{9}{4}y[/tex] --- this is just a false equation that cannot be a line.

2) [tex]y=x+\frac{9}{4}[/tex] --- this is a line with a slope of 1 and a y-intercept of 9/4

3) [tex]x=\frac{9}{4}x[/tex] --- this is also false

4) [tex]y=\frac{9}{4}x[/tex] --- this is a line with a slope of 9/4 and a y-intercept of 0.

Answer:

5 and 1

Step-by-step explanation:

for the first one, replace x with 2 and then do 6-1=5

for the second one replace x with 1. 1 to the second power is 1

Step-by-step explanation:

Example, i have 1 equation and i want to find x

2x - 1 = 5

2x = 5 + 1

2x = 6

x = 6/2

x = 3

So, value of x is 3

Answer:

Step-by-step explanation:

y = 5x

y = x + 30

Substitute y = 5x in second equation:

5x = x+ 30

4x = 30

x = 7.5.

and y = 5*7.5 = 37.5.

Answer:

x=8

Step-by-step explanation:

3(10-x)=6

30-3x=6

-30. -30

-3x/-3= -24/-3

Divide -3 to both sides

x=8

Answer:

2(x+7) = 2x+14 / 3(x+1) = 3x+3

Step-by-step explanation:

When you  see equations with parenthesis, that means you must do distributive property. So, whatever number is outside of the parenthesis, you multiply it by all the number inside of the parenthsis.

Answer:

6x² + 48x + 42

Step-by-step explanation:

2(x + 7) 3(x + 1) ← multiply the integers

= 6(x + 7)(x + 1) ← expand factors using FOIL

= 6(x² + 8x + 7) ← distribute parenthesis by 6

= 6x² + 48x + 42

Answer:

  w = ms +10e

Step-by-step explanation:

The basic idea is to undo what is done to w. Here, 10e is subtracted, and the difference is divided by m. We undo these in reverse order. To undo the division, we multiply by m. To undo the subtraction, we add the quantity that was subtracted. Any operation that we perform must be done to both sides of the equation.

  [tex]s = \dfrac{w - 10e}{m}\qquad\text{given}\\\\ms=w-10e\qquad\text{multiply by $m$}\\\\ms+10e=w\qquad\text{add $10e$}[/tex]

Usually, you want to write that with w on the left:

  w = ms +10e

Answer:

(2xy)³

Step-by-step explanation:

According to the Power Rule of Exponents:

[tex](ab})^{m} = a^{m}b^{m}[/tex]

We can apply the Power Rule of Exponents to the given exponential expression, 8x³y³, by taking the smallest factor that when cubed (or raised to an exponent of 3), will produce the same results as the original exponential expression.

8 is a perfect cube of 2:  ⇒  2 × 2 × 2 = 2³ = 8

The cube of x is x³:   ⇒  x × x × x = x³

The cube of y is y³  ⇒  y × y × y  = y³

Hence, we can take the least common factors, (2xy) and raise them to the third power:

(2xy)³ = 2³x³y³ =  8x³y³

Therefore, the correct answer is: (2xy)³

[tex]\\ \sf\longmapsto 8x^3y^3[/tex]

We know the rule of exponents

[tex]\boxed{\sf (ab)^m=a^mb^m}[/tex]

Now

[tex]\\ \sf\longmapsto 8x^3y^3[/tex]

[tex]\\ \sf\longmapsto 2^3x^3y^3[/tex]

[tex]\\ \sf\longmapsto (2xy)^3[/tex]

[tex]\\ \sf\longmapsto (2xy)(2xy)(2xy)[/tex]

Taxable income is a person's gross income minus allowable deductions.

The correct option is B.

As, Any gross income that is used to determine how much tax you owe is referred to as taxable income.

This is equal to your AGI less the total of either your itemized deductions or the standard deduction, whichever is greater, and, if available, the qualifying business income deduction.

So, Taxable income is a person's gross income minus allowable deductions.

Thus, the ideal solution is B.

Answer:

Step-by-step explanation:

x = 75°

75° + 75° + a = 180°

a + 150° = 180°

a = 180° - 150°

a = 30°

y + 30° = 90°

y = 90° - 30°

y = 60°

The slope is [tex]-\frac{5}{6}[/tex]

Step-by-step explanation:

Hi there!

We are given two points: (10, 63) and (94, -7)

We want to find the slope that passes through these lines

We can use the slope formula to find it

The formula for slope calculated from two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything needed to find the slope, let's just label their values to avoid confusion:

[tex]x_1=10\\y_1=63\\x_2=94\\y_2=-7[/tex]

Now substitute these values into the formula:

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-7-63}{94-10}[/tex]

Subtract the numbers:

m=[tex]\frac{-70}{84}[/tex]

Divide:

m=[tex]-\frac{5}{6}[/tex]

The slope of the line is [tex]-\frac{5}{6}[/tex]

Answer:

x= (2/5)-(2y/5)      (Im not sure if this is what you need but this is the answer simplified)

Step-by-step explanation:

Move all terms that don't contain x to the right side and solve.

Answer:

1: a. x=120, b. x=19, 2: mOPR=137, mSRQ=140, mPQT=83

Step-by-step explanation:

1.

a. since x is an exterior angle, we know x is the sum of the other 2 interior angles. the box in the corner means that angle is a right angle, or 90 degree angle. so x = 90 + 30, s=120

b. again, 103 is an exterior angle so 103 = 47-x +2x+38. simplify to get 103 = x+84, so x=19

2.

OPR is an exterior angle so mOPR = mPQR + mPRQ, or  2y+15 = 97 + y-21. simplify and solve for y to get y=61. plug this into 2y+15 to get mOPR = 137.

because SRQ is an exterior angle, it equals RPQ + PQR. first we need to find RPQ. since PQR is a triangle, PQR + PRQ + RPQ = 180. PRQ = y-21 = 40. so RPQ=180-97-40 = 43. so SRQ = 43+97 = 140. (you could also use the fact that PRQ + SRQ = 180)

the exterior angles added up together = 360, so OPR + SRQ + PQT = 360. plug in the known values to get PQT = 360 - 137 - 140 = 83
