The fraction bar represents which equation?

Step-by-step explanation:

y+4= 4(x-3)

y+4 =4x- 12

4x-12 -y -4=0

4x-y -16=0

4x-y=16

Answer:

Option  D. 7°C

Step-by-step explanation:

Let the temperature in Fahrenheit (F) and the temperature in Celsius(C)

The formula to convert Fahrenheit to Celsius is ⇒ F = 1.8 C + 32

So, to Convert 45° F to Celsius, substitute with with 45° F

45 = 1.8 C + 32

Solve for C

1.8 C = 45 - 32

1.8 C = 13

C = 13/1.8 = 7.222

Rounding to the nearest degree ⇒ 45° F = 7° C

The answer is option  D. 7°C

Answer: w= -9

Step-by-step explanation:

Set up an equation, 5 times a number is 5w, and 35 more, means plus 35. All of this is equal to -10, so the equation will be:

5w+35=-10

Subtract 35 from both sides

5w=-45

Divide by 5 on both sides

w= -9

Hope this helped!

Answer:

the answer is B

Step-by-step explanation:

you subtract 9/5 on both sides, find the common denominator which in this case would be 10. so 35-18 is 17. turn that into a mixed fraction and you get 1 and 7/10

Answer:

There are 13 cards for each suit so the first fraction is 13/52 and the next one is 13/51 as there is no replacement for the first card you pulled.

Multiplying them you get: 13/52*13/51= 169/2652,

Then you divide both sides by 13 to get: 13/204

So, the answer is C.

I hope this helps!

The probability of drawing a club and then a diamond consecutively from the deck without replacement is 13/204.

Option C is the correct answer.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of cards = 52

Number of clubs = 13

Number of diamonds = 13

Now,

The probability of drawing a club.

= 13/52

And,

The probability of drawing a diamond consecutively from the deck without replacement.

= 13/51

[ There will be only 51 cards in total since we are not replacing ]

Now,

The probability of drawing a club and then a diamond consecutively from the deck without replacement.

= 13/52 x 13/51

= 13/4 x 1/51

= 13/204

Thus,

13/204 is the probability of drawing a club and then a diamond consecutively from the deck without replacement.

Two numbers multiply into (-24) and adds up to (-10) are 2 & -12

Step-by-step explanation:

Here we need to find two numbers , with the following info:

Let us assume that two numbers are x & y .

two numbers multiply into (-24):

Two numbers are x and y , and there multiply is -24 i.e.

⇒ [tex]x(y) = -24[/tex]

two numbers adds up to (-10):

Two numbers are x and y , and there addition is -10 i.e.

⇒ [tex]x+y = -10[/tex] . .............. (1)

Let's solve this :

We know that , [tex](x+y)^2 = x^2 +y^2 +2xy[/tex]

⇒ [tex](x+y)^2 = x^2 +y^2 +2xy[/tex]

⇒ [tex](-10)^2 = x^2 +y^2 +2(-24)[/tex]

⇒ [tex]100 = x^2 +y^2 -48[/tex]

⇒ [tex]x^2 +y^2 =148[/tex]

Now,

⇒ [tex](x-y)^2 = x^2 +y^2 -2xy[/tex]

⇒ [tex](x-y)^2 = (148) -2(-24)[/tex]

⇒ [tex](x-y)^2 = (148) +48=196 = 14^2[/tex]

⇒ [tex]x-y = 14[/tex]     .......... (2)

Let's solve equation 1 & 2 by adding (1)+(2):

⇒ [tex](x+y)+(x-y) = -10 +14[/tex]

⇒ [tex]2x=4[/tex]

⇒ [tex]x=2[/tex]

Putting value of [tex]x=2[/tex] in [tex]x-y = 14[/tex] :

⇒ [tex]2-y = 14[/tex]

⇒ [tex]y = -12[/tex]

Therefore, two numbers multiply into (-24) and adds up to (-10) are 2 & -12.

Answer:option c

Step-by-step explanation:

An Isosceles Right Triangle is a right triangle that consists of two equal-length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.

So the correct answer is option c. It is an isosceles right triangle.

Since the two sides are equal it makes the corresponding angle congruent. Thus, in an isosceles right triangle two sides are congruent and the corresponding angles will be 45 degree each which sums to 90 degree. So the sum of three angles of the triangle will be 180 degrees.

The area of the isosceles right triangle follows the general formula of the area of a triangle that is (1/2) × Base × Height. In ∆QPR shown above with side lengths PQ = QR = x where PQ represents the height and QR represents the base, the area of isosceles right triangle formula is given by 1/2 × PQ × QR = x2/2 square units.

Find out how many passes does he  catch in 15 games

[tex]\frac{8}{3}=\frac{x}{15}\\\\x=8(15)/3\\\\x=40\ passes[/tex]

Answer: 40 passes

Step-by-step explanation:

Hi, to answer this we have to use proportions:

Proportion = Passes catched/ football games

Bobby catches 8 passes in 3 football games: 8/3

For 15 games: x/15

8 /3 = x/15

Solving for x

(8/3)15 =x

40 = x

He catches 40 passes in 15 games.

Answer: 116°

Step-by-step explanation:

The measure of arc AD is 116 degrees and it can be determined by using the properties of a circle.

Given that,

Angle ABD measures (4x + 10).

Angle ACD measures (5x − 2).

Circle E is shown.

Angles ABD and ACD intercept arc AD.

Angles BAC and BDC intercept arc BC.

We have to determine,

What is the measure of arc AD?

According to the question,

Angle ABD measures (4x + 10).

Angle ACD measures (5x − 2).

Circle E is shown.

Angles ABD and ACD intercept arc AD.

Angles BAC and BDC intercept arc BC.

In the given condition, Angle ABD and Angle ACD have inscribed angles, intercepting the same arc then by the intercept arc property.

Angle ABD = Angle ACD

[tex]\rm 4x+10 = 5x-2\\\\4x-5x = -2-10\\\\-x = -12\\\\x=12[/tex]

The value of x is 12.

Therefore,

The measure of arc AD is,

[tex]\rm Arc \ AD =A ngle \ ABD + Angle \ ACD\\\\Arc \ AD = (4x+10) + (5x-2)[/tex]

Substitute the value of x,

[tex]\rm Arc \ AD = (4x+10) + (5x-2)\\\\Arc \ AD = 4(12) +10+5(12) -2\\\\Arc \ AD = 48+10+60-2\\\\Arc \ AD = 116 \ degree[/tex]

Hence, the measure of arc AD is 116 degrees.

Step-by-step explanation:

42+6=48

Answer:

x = [tex]\frac{ln(16)}{ln(2)}[/tex]

Step-by-step explanation:

[tex]4^{2x-1} =8^{x+2}[/tex]

ln both sides like you would add the same number to both sides to keep the equation equivalent

[tex]ln4^{2x-1} = ln 8^{x+2}[/tex]

using log rules, exponents can be brought down as a constant multiplying ln

[tex](2x-1)ln(4) =(x+2)ln(8)[/tex]

use distributive property to remove parentheses

2xln(4) - ln(4) = xln(8) + 2ln(8)

isolate x

2xln(4) - xln(8) = 2ln(8) + ln(4)

rewrite the logs using log rules: ln(x) - ln(y) = ln([tex]\frac{x}{y}[/tex]) and the exponent rule stated above

xln([tex]4^{2}[/tex])-xln(8) = ln([tex]\frac{8^{2} }{4}[/tex])

factor out x

x(ln[tex]4^{2}[/tex]-ln8) = ln([tex]\frac{8^{2} }{4}[/tex])

again use log rules:  ln(x) - ln(y) = ln([tex]\frac{x}{y}[/tex])

x* [tex]ln(\frac{4^{2} }{8}[/tex][tex])[/tex]=  ln([tex]\frac{8^{2} }{4}[/tex])

now simplify the stuff inside the ln parentheses

x*ln(2) = ln(16)

Answer:

42

Step-by-step explanation:

I think it's 42 because 42/-6 is -7

Answer:

z = 42

Step-by-step explanation:

Given -7 = z/-6

Cross multiply

-7 x -6 = z

Negative times negative gives you positive.

42 = z

z = 42

You have the right equation.

p(x) = 0.586041x - 3,200,000

3200000 of course represents the deduction from the loan

0.586041 - this number represents the amount of money left after taxes (58.6041% of the total is left)

We get this by taking into account all the taxes on top of another...

35% federal tax = 65% left

35% federal tax and 8% state tax = 65% x 92% left

35% federal tax and 8% state tax and 2% local tax = 65% x 92% x 98% left = 58.6041%

To get the profit plug in the given taxable income for x.

p(6775989) = 0.586041(6775989) - 3,200,000 = $771,007.37 approx.
