Answer:

C. f(5) = 13 and f(-3) = -3

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 3

x = 5

x = -3

Step 2: Evaluate

x = 5

x = -3

We evaluate Separately.

Let x = 5

f(5) = 2(5) + 3

f(5) = 10 + 3

f(5) = 13

Now let x = -3.

f(-3) = 2(-3) + 3

f(-3) = -6 + 3

f(-3) = -3

Answer: Choice C

Answer:

7488 inches

Step-by-step explanation:

I think that this is the correct answer. The reason is that you have to multiply 72 x 104. I´m not 100% sure.

The required maximum area of the biggest possible square is with sides of a whole number length of 7396 inches².

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
Area of the leftover sheet = 72  × 104 = 7488 inches²

area of the square = 7488
a² = 7488
a = 86.53

Somehow, for  the biggest possible square to be with sides of whole number length,
The area is given as,
= 86²
= 7396 inches²

Thus, the required maximum area of the biggest possible square be with sides of whole number length  7396 inches².

Answer:

y=-3x+2

Step-by-step explanation:

Same slope = parallel. You can aso double check this answer by either graphing using the desmos online graphing calculator or by plugging in the point into the equation y = -3(2) + 2 --> y = -6 + 2 --> y = -4, so we are correct.

Answer:

y=-3x+2

Step-by-step explanation:

In this equation the slope is the same as the original equation (-3), but has a different y-intercept meaning that this line is parallel. As for satisfying the requirement that the line is parallel and passes through (2,-4), I plugged the coordinates into the equation y=-3x+b to get  -4=-3(2)+b, and then found what b would have to equal to make the equation true.

Step-by-step explanation:

59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7

59 / 7 - ( x + 8 / 7 ) = 19 / 7

59 / 7 - x - 8 / 7 = 19 / 7

- x = 19 / 7 - 59 / 7 + 8 / 7

- x = - 32 / 7

71 craft sticks per plastic bag

Step-by-step explanation:

Total craft sticks = 1,988

Total plastic bags = 28

She divided the craft sticks equally into 28 plastic bags for her students.

How many sticks did Mrs. Yamo put in each bag?

Craft sticks per plastic bag = Total craft sticks / Total plastic bags

= 1,988 / 28

= 71

Craft sticks per plastic bag = 71

Mrs. Yamo put 71 craft sticks in each plastic bag

Answer:     the answer is the first one

Step-by-step explanation:

Answer:

x=5 , y= -1

Step-by-step explanation:

You can see that one of the y's is negative while the other is positive, so you can add them together.

Now, negative 1 + positive 1 = 0, so the y's cancel out leaving only the x's.

Remember you can't add one part without adding the other so x+x = 2x, and 4+6=10. This makes the final equation 2x=10.

You can simplify that into x=5. This gives you the answer for x

Then substitute x=5 into any of the two equations (doesn't matter) I'll use the first one. So if you substitute it you get 5+y=4.

Simplified, y= -1

Therefore, x= 5 and y=-1

[tex]x^{2} -9x+20=0[/tex]

Step-by-step explanation:

[tex]x^{2} -3x+16=6x-4\\\\x^{2} -9x+20=0[/tex]

We have an expression in the form

[tex]\frac{f(x+\Delta x)-f(x)}{\Delta x}[/tex]

where the [tex]\Delta x[/tex] term is approaching 0, which is what the "lim" indicates (we're applying a limit).

Note how in [tex]f(x+\Delta x)[/tex], we effectively replace every copy of x with [tex]x+\Delta x[/tex]

Choice D is close, but it's missing the "lim" notation, so it's not 100% accurate.

Answer:

  (x, y) = (-2.5, -4)

Step-by-step explanation:

Since you are given an expression for y, it is convenient to substitute that into the second equation.

  2x -3(6x +11) = 7

  2x -18x -33 = 7

  -16x = 40 . . . . . . add 33

  x = -40/16 = -2.5

Using the equation for y, we find ...

  y = 6(-2.5) +11 = -15 +11 = -4

The solution is (x, y) = (-2.5, -4).

Given :

Initial weight of sumo wrestler, I = 90 kg.

Final weight of sumo wrestler, F = 138 kg.

Time taken, T = 8 months.

To Find :

Weight gain per month.

Solution :

Weight gain per month = ( Final weight - Initial weight ) ÷ Total number of month

[tex]W = \dfrac{138-90 }{8}\ kg/month\\\\W = 6 \ kg/month[/tex]

Therefore, weight gain per month is 6 kg/month.

Hence, this is the required solution.

The coordinates of the point P is (6/5, 17/5).

Given that, the points A(-2, 5) and B(2, 3) and the line segment divided in the ratio 4:1.

The Section formula is used to find the coordinates of the point that divides a line segment (externally or internally) into some ratio.

The section formula is [tex]P(x,y)=(\frac{mx_{2}+nx_{1} }{m+n}, \frac{my_{2}+ny_{1} }{m+n} )[/tex].

Here, m:n=4:1, (x1, y1)=(-2, 5) and (x2, y2)=(2, 3)

Now, P(x, y) = [tex](\frac{4\times 2+1 \times (-2)}{4+1} , \frac{4\times 3+1 \times 5}{4+1} )[/tex]

=(6/5, 17/5)

Therefore, the coordinates of the point P is (6/5, 17/5).

Answer:

The number of places correctly identified is 110 places

Step-by-step explanation:

The number of places he correctly identified will be;

11 + 4 + 86 + 9 = 110 places

By using compatible numbers, we refer to the fact that she use an estimate by making sure each of the numbers are closer to the nearest 10th or 5

so 4 will be 5

11 will be 10

86 will be 85

9 will be 10

Adding all of these together, we have

5 + 10 + 85 + 10 = 110

Answer:

D

Step-by-step explanation:

Option 4.

The vertex form of a parabola is

where, a is a constant (h,k) is the vertex.

The given function is

The vertex of the function is (0,0) and it goes through (-2, 4) and (2, 4).

It is given that the vertex of function g(x) is at (5,2).

Substitute h=5 and k=2 in the equation.

g(x) is passed through (3, 6).

 Divide both sides by 4.

Substitute a=1 in equation (2).

The function g(x) is g(x) =(x-2)2+5) .

Therefore, the correct option is 4.
