Can someone please help me anyoneeeee

number of cupcakes lynn made = x

number of cupcakes santo baked = 2x - 4

hope this helps and please mark me brainliesr. PLEASE!!!!

Answer:

y = 5

x = 1

Step-by-step explanation:

y = 3x + 2

-4x + 4(3x+2)=16

y=3x+2

-4x+(4*3x+4*2)=16

x = 1

y = 5

Answer:

x-coordinate = 1

y-coordinate = 5

Step-by-step explanation:

By using the substitution method, we substitute either x-term or y-term in any equation.

the term must be only the subject in order to substitute in.

Our equation that has only the subject is the first equation.

Substitute y = 3x+2 in the second equation.

[tex] - 4x + 4(3x + 2) = 16[/tex]

Distribute 4 in 3x+2

[tex] - 4x + 12x + 8 = 16[/tex]

The constant cannot add up or subtract with the variable. Therefore, move 8 to subtract 16 on another side.

[tex]12x - 4x = 16 - 8 \\ 8x = 8[/tex]

Move 8 to divide 8 on the another side.

[tex]x = \frac{8}{8} \\ x = 1[/tex]

Our next goal is to find the y-value by substituting x = 1 in any given equation.

I will substitute x = 1 in the first equation. (You can substitute in the second equation if you want.)

[tex]y = 3(1) + 2 \\ y = 3 + 2 \\ y = 5[/tex]

Answer Check

Checking is to make sure that we have got the right answer. We can check the answer by substituting y-value and x-value in both equations.

[tex]x = 1 \\ y = 5[/tex]

First Equation Check

[tex]5 = 3(1) + 2 \\ 5 = 3 + 2 \\ 5 = 5[/tex]

The equation is true. Therefore, the answer is correct for first equation.

Second Equation Check

[tex] - 4(1) + 4(5) = 16 \\ - 4 + 20 = 16 \\ 16 = 16[/tex]

The equation is true. Both equations are true for x = 1 and y = 5.

Therefore, the answer is (1,5)

Answer: 248 boxes

Step-by-step explanation:

They produce boxes at a rate of 52 boxes an hour yet after only 3 hours they had 404 boxes.

The number they were supposed to have in 3 hours is:

= 52 * 3

= 156 boxes

They instead had 404 so the rest must have been there when they opened:

= 404 - 156

= 248 boxes

Answer:

8π(2.5)^2

Step-by-step explanation:

volume = π * r^2 * h

Answer:

  138°

Step-by-step explanation:

The angles of the linear pair are supplementary.

  ∠MLO = 180° -∠MLJ = 180° -42°

  ∠MLO = 138°

Answer:

angle MLO =180° - angle MLJ =(180°-42°)= 138°

Answer:

40%

Step-by-step explanation:

Given that :

Number of people surveyed = 2500

Number of satisfied buyers = 1000

Thus, the percentage of satisfied buyers :

(Satisfied buyers / total surveyed) * 100%

(1000 / 2500) * 100%

0.4 * 100 = 40%

40% of people surveyed were satisfied

slope = 17

- use the formula for slope, and simply plug it in.

Answer:

-n - 9

Answer:

-n-9

Step-by-step explanation:

3n-10+1-4n

(3n-4n)+(-10+1)

-n-9

Answer:

3.2

Step-by-step explanation:

Step 1: Multiply the whole number by the denominator: 3 × 5 = 15.

Step 2: Add the product you got in Step 1 to the numerator: 15 + 1 = 16.

Step 3: Divide the sum from Step 2 by the denominator: 16 ÷ 5 = 3.2. That's it folks!

Answer:

3.2

Step-by-step explanation:

Step 1: divide numerator (1) by the denominator (5): 1 ÷ 5 = 0.2. Step 2: add this value to the the integer part: 3 + 0.2 = 3.2. So, 3 1 / 5 = 3.2.

because I love math

Answer:

Step-by-step explanation:

inside angle = 180 = 2x + 2x + 20 + 3x - 10 + 2x - 10

substitute the value of x = 20 into angle L, M, N, P

L = 2x + 20

L = 2(20) + 20

M = 3x - 10

M = 3(20) - 10

N = 2x - 10

N = 2(20) - 10

P = 2x

P = 2(20)

∠L + ∠M + ∠N + P = 180

60° + 50° + 30° + 40° = 180

Answer:

It's 0

Step-by-step explanation:

Answer:

the formula = y = mx+c,

if slope is -5 and y intercept is 8,

y = -5x+8

or

y= 8-5x

Answer:

140km after 2 hours

Step-by-step explanation:

Answer:

2=140

Step-by-step explanation:

Given:

Two points are N(-1,-11) and P(-1,-3).

To find:

The value of NP.

Solution:

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Two points are N(-1,-11) and P(-1,-3). Using distance formula, we get

[tex]D=\sqrt{(-1-(-1))^2+(-3-(-11))^2}[/tex]

[tex]D=\sqrt{(-1+1)^2+(-3+11)^2}[/tex]

[tex]D=\sqrt{(0)^2+(8)^2}[/tex]

On further simplification, we get

[tex]D=\sqrt{0+64}[/tex]

[tex]D=\sqrt{64}[/tex]

[tex]D=8[/tex]

Therefore, the value of NP is 8 units.

Answer:

103 and 102

Step-by-step explanation:

u add them together

- a midline of a trapezoid is always half of the sum of the legs.

so,

2TW = UV + SX

now plug in and solve,

2(14p + 22) = 17p + 4p + 65

28p + 44 = 21p + 65

7p = 21

p = 3

Answer:

jim is correct, x does equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct

Step-by-step explanation:

so, all angles of a triangle have to add up to 180;

(15x) + (8x - 11) + (3x + 9) = 180

15x + 8x - 11 + 3x + 9 = 180

add your common numbers

26x - 2 = 180

add 2

26x = 182

divide 26

x = 7

put it back into the equation

15(7) + 8(7) - 11 + 3(7) + 9 = 180

180 = 180

Answer:

318.75

Step-by-step explanation:

15% of 375 is 56.25. then you just subtract 56.25 from 375 and get 318.75

Answer:

$ 56.25

Step-by-step explanation:

Reduction = 15% of 375

                [tex]= \frac{15}{100}*375\\\\= 0.15*375\\= $56.25[/tex]

Basically, in a function, you draw a vertical line. If that vertical line crosses the function more than once, then it is an invalid function.

Let me know if you need an example and I'll edit a picture in for you.

Answer:

A vertical line test is used to find out whether if a curve is a graph of a function or not.  If you are able to draw a vertical line, and it intersects more than one point on the curve, then it is not a function.

Step-by-step explanation:

Given:

The function is

[tex]f(x)=x^2+3[/tex]

To find:

The slope of the tangent line at x = 11.

Solution:

The slope of the tangent is the value of f'(x) at x=11.

We have,

[tex]f(x)=x^2+3[/tex]

Differentiate with respect to x.

[tex]f'(x)=2x+0[/tex]              [tex]\left[\because \dfrac{d}{dx}x^n=nx^{n-1},\dfrac{d}{dx}C=0,\text{ where C is constant}\right][/tex]

[tex]f'(x)=2x[/tex]

Substitute x=11 in the above equation.

[tex]f'(11)=2(11)[/tex]

[tex]f'(11)=22[/tex]

Therefore, the slope of the tangent at x=11 is 22.
