Answer:

2.20

Step-by-step explanation:

So add +2 both sides that cancels 2 and that makes it -11.00 now divide it by -5 and x is by itself

So when you divide it x=2.20

Hope that helps

Answer:

y = 1x - 1 is the slope-intercept form

Answer:

y=1x-1

Step-by-step explanation:

Slope Intercept Form is y=mx+b where m is the slope, x is the number of x times, b is the y intercept, y intercept is the part of a line where the x is 0 and the y touches a y axis, vice versa for x intercept

Choice A) Real Numbers

Choice F) Rational Numbers

===============================================

Explanation:

Any number you encounter so far in your math class is a real number, assuming your teacher hasn't covered complex numbers yet. So -7/16 is a real number.

It is also a rational number. Rational numbers are of the form p/q where p and q are integers. The value of q cannot be zero. Since it is rational, that means it's not irrational.

Since -7/16 = -0.4375 has a fractional or decimal part, it is not a whole number, integer, or natural number. Those numbers only deal with values that don't have any fractional parts.

But if the answer shown is the correct answer, I think your computer read wrong, because those answers are the exact same :/

Answer:

The answer is 25z^2+2-15z

Step-by-step explanation:

The form one will often see polynomials in is called standard form. It is when the terms are ordered in highest degree to lowest degree. For example, when given the polynomial x4+2x3+x+11, it is in standard form because 4 is the highest power, then 3 and 1.

Answer:

  a[n] = n² +2n +9

Step-by-step explanation:

First differences are ...

  17-12 = 5; 24-17 = 7; 33-24 = 9 . . . . . . define d1=5

So, second differences are ...

  7-5 = 2; 9-7 = 2 . . . . . . . define d2=2

The coefficient of the n² term is half the second difference (=d2/2). The 0-th term will be smaller than the first term by the difference between the first first difference and the second difference (d1-d2):

  a0 = a1 -(d1 -d2) = 12 -5 +2 = 9

So, the quadratic rule will be ...

  a[n] = n² +9 +kn

for some value of k.

We can find k using the first term of the sequence.

  a[1] = 1² +9 +k·1 = 12

  k = 12 -10 = 2

Then the rule is ...

  a[n] = n² +2n +9

A

Step-by-step explanation:

100% slope is -3 because you need to move down 3 times which is -3 and move to the right once which is 1

Slope= rise/run

Slope=-3/1 which equals -3

y-intercept= 2 because you just look at the y-axis and see any points that connects to it while the x is zero

Answer:

C. 39

Step-by-step explanation:

m∠3 ≅ m∠5

4x - 7 = 6x - 81

-7 = 2x - 81

74 = 2x

37 = x

m∠5 = 6(37) - 81 = 141

m∠8 = 180 - 141 = 39

Step-by-step explanation:

15 - 2(7 - x) = 7

collect like terms

-2(7 - x) = 7 - 15

-2(7 - x) = -8

divide both sides by -2

7 - x = -8/-2

7 - x = 4

collect like terns

-x = 4 - 7

-x = -3

dividing both sides by -

x = 3

Answer:

Step-by-step explanation:

15-2(7-x)=7

15-14+2x=7

Answer:

2.125 liters of juice

Step-by-step explanation:

Total liters of juice = 9

Total liters left = 0.5

Total liters used = Total liters of juice - Total liters left

= 9 - 0.5

= 8.5

Total liters used = 8.5 liters

He pours equal amounts of the juice into 4 pitcher

Liters per pitcher = Total liters used / number of pitchers

= 8.5 / 4

= 2.125 liters

Liters per pitcher = 2.125 liters

Each pitcher has 2.125 liters of juice

Answer:hope u understand it better

Step-by-step explanation:  y=3

We simplify the equation to the form, which is simple to understand

y=3

We move all terms containing y to the left and all other terms to the right.

+1y=+3

We simplify left and right side of the equation.

+1y=+3

We divide both sides of the equation by 1 to get y.

y=3

Answer:

r = 7

Step-by-step explanation:

60 = -24 + 12r​

+24  +24

84 = 12r

84 ÷ 12 = r

7 = r

Check:

60 = -24 + 12r

-24 + 12(7)

-24 + 84 = 60

Step-by-step explanation:

y = 5x + 3

y = 5.5x + 2

0.5x = 1

x = 2

y = 13

Answer:

The answer is y = 13

y = 5.5x + 2

x = 2

(5.5 * 2) + 2

(11) + 2 = Y or 13

Answer:

Selling price= $58.5

Step-by-step explanation:

Giving the following information:

Guitar cost price= $45

Mark up percentage= 30%

To calculate the selling price of the guitar, we need to use the following formula:

Selling price= cost price*(1+mark up)

Selling price= 45* (1+0.3)

Selling price= 45*1.3

Selling price= $58.5

Answer:

x = 4.8

AC = 16.8

Step-by-step explanation:

From the picture attached,

In ΔABE and ΔACD

BE║CD, and the AC and AD are the transversal lines.

∠ABE ≅ ∠ACD [Corresponding angles]

∠AEB ≅ ∠ADC [Corresponding angles]

ΔABE ~ ΔACD [By AA property of similarity of two triangles]

And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.

[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]

[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]

[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]

10(x + 12) = 12 × 14

10x + 120 = 168

10x = 168 - 120

x = 4.8

AC = x + 4.8

     = 12 + 4.8

     = 16.8

Answer: First, you need to figure out 22 times 2 = 44. Then, you need to multiply the original ratio by 44 to get the answer.

Step-by-step explanation:

Answer:

First you need to creative graph or a table. Then look at how much water and how much you drink mix there is add that up and see if you get it then whatever you get divide that by 22. If that doesn’t help what you do is take the 8÷22 and the 22÷3 and that should tell you how much you need for each one

Answer:

If it is yards to miles, you divide. Precisely by 1760.

Therefore, if you were to divided 100 bye 1760, it would be around 0.0568182

Step-by-step explanation:

1 yard is 1/1760 fraction of a mile therefore football field will be 0.05682 miles long.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.

Another example could be kilo gram to gram.

1 mile = 1760 yards.

Divide by 1760

1760/1760 yards = 1/1760 mile

1 yard = 1/1760 mile

Multiply by 100

100 yard = 100/1760 mile

100 yard = 0.05682 mile

Hence "1 yard is 1/1760 fraction of a mile therefore football field will be 0.05682 miles long".
