y = 7x +3 slope is rise over run with would be 7/1 and y intercept is 3

The equation in the slope-intercept form is y=7x+3.

Given:

Find:

Solution:

We will use y = mx+b where m = slope and b = y-intercept.

y = mx+b

Now, putting (1,10) in the place of x and y and slope as 7, we get;

10 = 7*1 + b

b = 10-7

b=3

So, the y-intercept is 3.

Now, putting the y-intercept in the slope-intercept equation, we get;

y = 7x+3

Hence, the equation in slope-intercept form is y=7x+3.

x^2-5x-36 =0

=》(×+4)(x-9) =0

=》 x = 9 or -4

positive solution for x is 9

For this case we must find the positive solution of the following quadratic equation:

[tex]x ^ 2-5x-36 = 0[/tex]

To find the solutions we factor, that is, we look for two numbers that when multiplied give as result -36 and when summed give as result -5.

These are:

-9 and +4

[tex]-9 * 4 = -36\\-9 + 4 = -5[/tex]

So, we have:

[tex](x-9) (x + 4) = 0[/tex]

The roots are:

[tex]x_ {1} = 9\\x_ {2} = - 4[/tex]

The positive solution is 9.

Answer:

9

For this case we have:

Let x be the variable that belongs to the real numbers. Then, all reals less than 70 can be expressed as:

ANSWER

D. [tex]126 {in}^{3} [/tex]

EXPLANATION

The formula for calculating the volume of a rectangular prism is

[tex]Volume =lbh[/tex]

The given rectangular prism has

length,

[tex]l = 8 \: in[/tex]

The width is

[tex]w = 4 \frac{1}{2} in[/tex]

and the height is

[tex]h = 3\frac{1}{2} in[/tex]

We substitute the values into the formula to obtain;

[tex]Volume =8 \times 4 \frac{1}{2} \times 3 \frac{1}{2} [/tex]

[tex]Volume =8 \times 4.5 \times 3.5[/tex]

[tex]Volume =126 {in}^{3} [/tex]

Answer:

The correct answer is option D.  126 in³

Step-by-step explanation:

Formula:-

Volume of cuboid - lbh

l - Length of cuboid

b - Breadth of cuboid

h - Height of cuboid

To find the volume of prism

Here rectangular prism is like a cuboid.

l = 8 in, b = 4 1/2 = 9/2 and h = 3 1/2 = 7/2

Volume = lbh

     = 8 * 9/2 * 7/2 = 126 in³

Therefore the correct answer is option D.  126 in³

Alright. We don't have the question, but Im going to assume it.

2 tires = $45

Later Sold for $65

Revenue is $20

If you mean sold both for each -

Revenue is $85

For this case we can indicate the profits obtained by Malik.

[tex]P = p-c[/tex]

Where:

P: They are the profits

p: It is the sale price

c: It's the cost

We have Malik buy the tires at $ 45, then the cost is $ 45. As he sold them at $ 65 then the sale price is $ 65.

We have:

[tex]P = 65-45\\P = 20[/tex]

So, Malik made a profit of $ 20 $

Answer:

Malik made a profit of $ 20

Answer:

So for this problem, we can use the formular:

(A + B)² = A² + 2AB + B²

Our orginal expression is: (x + 4)². In this expression, A can be written as x, B represents for 4, that leads to our answer:

(x + 4)² = x² + 2 . 4x + 4² = x² + 8x + 16

The correct answer will be D

Answer:  the correct option is (D) [tex]x^2+8x+16.[/tex]

Step-by-step explanation:  We are given to select the expression that is equivalent to the following expression :

[tex]E=(x+4)^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We will be using the following formula :

[tex](a+b)^2=a^2+2ab+b^2.[/tex]

Using the above formula, the expression (i) gives

[tex]E\\\\=(x+4)^2\\\\=x^2+2\times x\times4+4^2\\\\=x^2+8x+16.[/tex]

Thus, the required equivalent expression is [tex]x^2+8x+16.[/tex]

Answer:32 black

6 white long sleeve shirts

Step-by-step explanation:

62+6=68

100-68=32

Answer:

Step-by-step explanation:

Since out of 62 who preferred short- sleeved shirts, half were white and half were white.

So members who preferred black and white short sleeved T- shirts = [tex]\frac{62}{2}[/tex] = 31 each

Since members who liked white T-shirts = 37

So members who preferred long sleeved white T-shirts = 100 - (37+31) = 32

Therefore, the table formed will be

                         Short-sleeved          Long sleeved            Total

Black                         31                             32                        63

White                         31                               6                         37

Total                          62                             38                        100

The third one cuz (0,1) is a point then you go down 3 over one

Graph 2 is the graph that represents the linear function y = –3x + 1

Points on graph 2 are (0,1) (-1,4) (1,-2)

Substitute the points in the linear function

(0,1)

y = –3x + 1

y = -3*0 +1

y = 1

(0,1) is correct point

(1,-2)

y = –3x + 1

y = -3 * 1 + 1

y = -3 +1

y = -2

(1,-2) is the correct point

Therefore, graph 2 is the correct answer

Answer:

After 11 years the value of the investment reaches $1500.00

.

Step-by-step explanation:

The formula used for finding time (when the value reaches certain amount) is:

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

where A= Future VAlue

P= Principal Value

r= rate of interest (in decimal)

n= no of times investment is compounded

t= time

Putting the values given and finding Time t,

A= $1500

P= $1200

r= 2% or 0.02

n= 4 (compound quarterly)

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

[tex]1500= 1200(1+\frac{0.02}{4})^{4t}[/tex]

Dividing both sides by 1200 and solving 0.02/4 = 0.005

[tex]1.25= (1+0.005)^{4t}[/tex]

[tex]1.25= (1.005)^{4t}[/tex]

Since t is in power we take the logarithm ln on both sides.

The rule of logarithm says that the exponent can be multiplied with the base when taking log

[tex]\ln1.25=ln( 1.005)^{4t}\\\ln1.25=4t * ln( 1.005)\\0.22 = 4t * 0.005\\Solving\,\,\\\frac{0.22}{4*0.005} = t\\=> t= 11\, years[/tex]

Answer:

Solution is (1,7).

Step-by-step explanation:

We need to find the solution of the system of following equations.

y= 5x + 2        eq(1)

3x = -y +10      eq(2)

We will solve the equations using Substitution method to find the values of x and y

we put value of y from eq (1) into eq (2), The eq(2) will be:

3x = - (5x + 2) + 10

3x = -5x -2 +10

3x+5x = -2+10

8x = 8

x= 1

Now, putting value of z in eq(1) to find value of y

y = 5x +2

y = 5(1) + 2

y = 5+2

y = 7

So, Solution is (1,7).

64 bowls because if you Multiply eight times 32. You would get 256 and then you divide that into four and would get 64 which is your answering

the greatest number of bowls of ice cream Kia can serve is 64.

The student wishes to determine the greatest number of bowls of ice cream that can be served given certain quantities of ice cream and serving sizes. To solve this, we first calculate the total amount of ice cream by adding the quantities of vanilla and chocolate ice cream. Kia bought 2 cartons of vanilla and 6 cartons of chocolate, each containing 32 ounces. Thus, the total amount of ice cream is (2 + 6) × 32 ounces. Each bowl served contains 4 ounces of ice cream. To find the number of bowls, we divide the total ounces of ice cream by the ounces per bowl. This yields (8 × 32) ÷ 4, which calculates to 64 bowls. Therefore, the greatest number of bowls of ice cream Kia can serve is 64.

Answer:

-109

Step-by-step explanation:

Arithmetic sequence formula:

an = a1  + d(n - 1) where d = -4 and a1 = 19

so

a(33) = 19 - 4(33-1)

a(33) = 19  - 4(32)

a(33) = 19 - 128

a(33) = -109

The missing term : -109

Answer:

-109

Step-by-step explanation:

As x changes from 1 to 2, 2 to 3, and 3 to 4, each change in x is 1. The  corresponding changes in y from 19 to 15, from 15 to 11, and from 11 to 7, are each a change of -4 in y. For each change of 1 in x, the corresponding change in y is -4. From 4 to 33 in x, the change is 33 - 4 = 29. The corresponding change in y is 29 * (-4) = -116.

7 + (-116) = -109

Answer:

the answer is D:  the median of both the dot plot A and B is the same

Step-by-step explanation:

median is the middle value; after arranging the data in ascending or descending order...the mean of the two values is an even # of values

The median of dot plot A and median of dot plot B is 5; so therefore, the pots A and B are the same.

Answer:

the median of both thedot plots A and B is the same.

Step-by-step explanation:

The median is the middle value after arranging the data in an ascending or descending order, or the mean of the two middle values if there is an even number of values.

The median of dot plot A and the median of dot plot B is 5.

Therefore, the median of both thedot plots A and B is the same.

For this case we have that the equation of the border line of the region is given by:

[tex]y = -2x-3[/tex]

To know the sign of inequality, we must evaluate a point that belongs to the region and verify if it is fulfilled.

As the border line is dotted, we discard options A and C.

Then, we evaluate the point (-2, -4)

Option B: [tex]y <-2x-3[/tex]

[tex]-4 <-2 (-2) -3\\-4 <4-3\\-3 <1[/tex]

Is fulfilled!

Thus, the region is given by the inequality of option B.
