I need help you solve this by using elimination and substitution thank you

Answer:

I think 83 ÷ 10 and it said that it incorrect

Step-by-step explanation:

Answer:

88.2          

Step-by-step explanation:

1) Find d

-20 = d + 6      original equation

-20 - 6 = d        subtract 6 from both sides to isolate the variable

-26 = d             simplify like terms

d = -26             answer

2) Plug it in expression

5 - 3.2d             original expression

5 - 3.2 (-26)       substitute value d for -26 (as calculated above)

5 + 83.2        PEMDAS (multiply first...don't subtract 5-3.2 and then multiply!)

88.2           simplify like terms and here is your answer

Answer:

Yes

Step-by-step explanation:

For every one x value is equal to one y value, therefore it's a one-to-one function.

Answer:

Its the green answer

Step-by-step explanation:

- The asymptote is on x=4 so with that we can rule out blue and red.

- the range is shown on the x-axis so it‘s green.

Answer:

Red

Step-by-step explanation:

The range of a function is the set of all of its y values. We can notice that the equation has a horizontal asymptote of y = -3, which basically means the value of y cannot be -3. So, it would be expressed as:

-∞ < y < -3 and -3 < y < ∞

This is the red option.

Answer:

B

Step-by-step explanation:

2x+3 is a factor of f(x) means that f(x) = (2x+3)* something else

to find the root or the zero:

2x+3 = 0 so 2x = -3; x= -3/2 so B is correct

Answer:

c

Step-by-step explanation:

Answer:

5x+4=-6

5x=-6-4

5x=-10

x=-10/5

x=-2

Step-by-step explanation:

Answer:

[tex] \sf \: x = - 2[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 5x + 4 = -6

Then the value of x will be,

→ 5x + 4 = -6

→ 5x + 4 - 4 = -6 - 4

→ 5x + 0 = -10

→ 5x = -10

→ 5x ÷ 5 = -10 ÷ 5

→ [ x = -2 ]

Hence, the value of x is -2.

Answer:

The total area is 594cm.²

Step-by-step explanation:

The top and bottom each have a length of 36 cm.

Blue side:

36/3= 12cm. (36/3 for the length of one side of a blue square)

12*12= 144cm.² (area of one blue square)

144*3= 432cm.² (area of all the blue squares)

Orange side:

36/8= 4.5cm. (the length of one side of an orange square)

4.5*4.5= 20.25cm.² (the area of one orange square)

20.25*8= 162cm.² (the area of all the orange squares)

Total area:

432+162= 594 cm.²

I hope this makes more sense, have a great day :D

Answer:

The shoreline places would get more rain

Step-by-step explanation:

Answer:

The inland would have warmer winters and colder summers, I believe.

Step-by-step explanation:

Water tends to heat up eaiser and cause humidity which makes everything feel hotter, so the summers would be super hot by the shore compared to farther inland.

Answer:

2 1/3 hours or 2 hrs, 20 min

Step-by-step explanation:

1 5/6 + 1/2

make mixed number into improper fraction and change 1/2 to 3/6

11/6 + 3/6 = 25/6

14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min

Answer:

cost price of shoes with tax=$86.00

Let cost price of a shoes be x

tax paid=rate of tax*amount tax/100

=7.5*$86.00/100

=645/100

=$6.45

Therefore he paid $6.45 tax

Now,original price of a shoes=cost price of a shoes with tax-tax paid

=$86.00-$6.45

=$79.55

Therefore,original price of the shoes is $79.55

Answer:

38°

Step-by-step explanation:

The measure of angle NPM is 38°.

➠ ∠MPJ + ∠LPM = 180°

➠ ∠MPJ + 90° = 180°

➠ ∠MPJ = 180° – 90°

➠ ∠MPJ = 90°

∠NPM = ∠MPJ – ∠JPN

➠ ∠NPM = 90° – 52°

➠ ∠NPM = 38°

Answer:

659.82m^3

Step-by-step explanation:

Given data

Height= 5 m

Radius= 3m

The expression for the surface area is given as

SA= 2πr^2+2πrh

SA= 2*31.42*3^2+ 2*3.142*3*5

SA= 2*31.42*9+ 2*3.142*3*5

SA= 565.56+ 94.26

SA= 659.82m^3

Hence the volume of the 659.82m^3

Answer:

radian = pi/6

degree = 30 degrees

Step-by-step explanation:

Answer:

it's answer is 73°

Step-by-step explanation:

< DCB = 50°

< ACB = x

< CAB = 57°

< ABC = < DCB = 50° {Being alternate angles }

Now

x + 50° + 57° = 180° { being sum of angles of triangle }

x + 107° = 180°

x = 180° - 107°

Therefore x = 73°

Answer:

1.

d - adjacent

e - hypotenuse

f - opposite

2.

[tex]\sin \theta = \frac{12}{13},\\\\\cos \theta = \frac{5}{13},\\\\\tan \theta = \frac{12}{5},[/tex]

Step-by-step explanation:

1. The opposite side of an angle is the side that the angle faces or forms. The hypotenuse of a right triangle is always the longest side of the right triangle. The adjacent side is one side or leg next to the angle that is not the hypotenuse.

2. In right triangles only:

The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)

The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus, we have:

[tex]\sin \theta = \frac{12}{13},\\\\\cos \theta = \frac{5}{13},\\\\\tan \theta = \frac{12}{5},[/tex]
