-7(3x + 5) + 20 = 5(3 - 5x) + 4x
Is it no solution/ many solutions or infinite

Answers

Answer 1

Answer:

0= 30

Step-by-step explanation:

-7(3x+5) +20=5)3-5x)+4x

-21x-35+20=5)3-5x)+4x

Add the numbers

-21x-35+20=5)3-5x)+4x

-21x-15=5)3-5x)+4x

Rearrange terms

-21x-15=5)3-5x)+4x

-21x-15=5(-5x+3)+4x

Distribute

-21x-15=-25x+15+4x

Combine like terms

-21x-15=-21x+15

Add 15 to both sides of the equation

-21x-15+15=-21x+15+15

Simplify

Add the numbers

-21x=-21x+30

add 21 to both sides of the equation

-21x+21x= 21x+30+21x

Simplify

combine like terms

0=30

What is the value of x and y in the following figure?

Answers

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°

I hope I've helped you

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

The required values are ~

[tex] \boxed{x = 75 \degree}[/tex]

and

[tex] \boxed{y = 60 \degree}[/tex]

[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]

As it's shown in the figure, the sides opposite to x and Angle 75° are equal. So the corresponding Angles are also equal to one another.

that is ~

[tex]x = 75 \degree[/tex]

I have taken an angle and marked it as " m " in the attachment.

So, according to Angle sum property of a triangle,

[tex]m + x + 75 \degree = 180 \degree[/tex]

[tex]m + 75 \degree+ 75 \degree= 180 \degree[/tex]

[tex]m + 150 \degree= 180 [/tex]

[tex]m = 180 \degree - 150 \degree[/tex]

[tex]m = 30 \degree[/tex]

now, it's given that the sum of Angle y and Angle m is 90°

hence,

[tex]m + y = 90 \degree[/tex]

[tex] 30 \degree + y = 90 \degree[/tex]

[tex]y = 90 \degree - 30 \degree[/tex]

[tex]y = 60 \degree[/tex]

Find the slope of the line that passes through (10, 63) and (94, -7).

Answers

Answer:

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]

Hope this helps!

Which linear equation represents a line with a slope of 94 and a y-intercept of 0?

1). y = 9/4y

2). y = x + 9/4

3). x = 9/4x

4). y=9/4x

Answers

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.


[tex]s = \frac{w - 10e}{m} [/tex]
I'm trying to solve for w​

Answers

9514 1404 393

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

Taxable income is a person's gross income minus
O A. hours worked
O B. allowable deductions
C. profits
O D. revenue

Answers

Allowable deductions I think

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.

new question!! pls help lol ty

Answers

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

Write 8x³y³ as the power of a product.

Answers

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 = = 8

The cube of x is x³:   ⇒  x × x × x =

The cube of y is y³  ⇒  y × y × y  =

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]

8=2^3x^3=(x)^3y^3=(y)^3

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]
