Answer:

$23

Step-by-step explanation:

let j be jacob"s money

Then angie is 3j, and Erin is 3j+35 so 7I

=161

j=23

Answer: Erin - $104; Angie - $69; Jacob - $23.

(please give me brainlest ❤️)

Step-by-step explanation:

JACOB has least amount of money, so let's say that he has :

x amount of money

ANGIE has 3 times more than jacob:

Angie has 3x

ERIN has $35 more money than Angie:

3x+35

their money together is $196, that means if we add all of their money, it will be equivalent of 196:

3x+35+3x+x=196

now lets find x value.

put all the xes on right side and all known numbers on left side.

i think u know that when it goes to another side it changes sign; for example - makes + and × makes /

3x+35+3x+x=196

7x=161

x=161/7

x=23

now plug x values for each kid:

so Jacob had x=23

Angie had 3x=3×23=69

and Erin had 3x+35=69+35= 104

lets check our answer:

23+69+104=196

196=196

so sum of their money really gives us $196.

Answer:

There is no point of the form (-1, y) on the curve where the tangent is horizontal

Step-by-step explanation:

Notice that when x = - 1. then dy/dx becomes:

dy/dx= (y+2) / (2y+1)

therefore, to request that the tangent is horizontal we ask for the y values that make dy/dx equal to ZERO:

0 = ( y + 2) / (2 y + 1)

And we obtain y = -2 as the answer.

But if we try the point (-1, -2) in the original equation, we find that it DOESN'T belong to the curve because it doesn't satisfy the equation as shown below:

(-1)^2 + (-2)^2 - (-1)*(-2) - 5 = 1 + 4 + 2 - 5 = 2  (instead of zero)

Then, we conclude that there is no horizontal tangent to the curve for x = -1.

Answer:

7 squares

Step-by-step explanation:

Key skills: Counting, Averages

1) Based on what I counted, there are 11 columns, and 53 squares. If you want an average of 5 squares per column and you have 12 columns, the total number of squares you want is 60.

2) Since there are already 53 squares present, you need 60-53 = 7 squares more.

Hope you understood and have a nice day!!

answer:

should be 7 squares.

Answer:

The value of 9x+2 when x=3 is 29

Step-by-step explanation:

Algebraic Expressions

We are given the expression

9x + 2

And it's required to evaluate the expression when the value of x is 3.

It can be done by substituting x by 3:

9*3 + 2

=27 + 2

=29

The value of 9x+2 when x=3 is 29

We can use 1/8 measuring cup two times.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

A cup of measurement 1/8.

Now,

we have to measure 1/4 from the cup using cup of measurement 1/8.

So, we can measure it two times.

as, 1/8+ 1/8

= 2/8

=2/4.

Answer:

Graph is below.

Step-by-step explanation:

The solutions of the equations are : x = [8 ± √ 40] / 4

Given,

Y=2x² - 8x+3

Now,

To get the solution of equation equate it to 0 .

2x² - 8x+3  = 0

By quadratic formula,

x = -b ± √ b² - 4ac/2a

Substitute the values in the formula,

x = [8 ± √ 64 - 4(2)(3)] / 2* 2

x = [8 ± √ 40] / 4

Now plot the points in the graph. The graph is attached below.

Answer:

The average rate of change of the function in this interval is of 18.

Step-by-step explanation:

The average rate of change of a function [tex]f(x)[/tex] in an interval from a to b is given by:

[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]

In this question:

[tex]f(x) = x^2 + 6x[/tex]

Where x goes from 5 to 7.

This means that [tex]b = 7, a = 5[/tex]. So

[tex]f(7) = 7^2 + 6(7) = 49 + 42 = 91[/tex]

[tex]f(5) = 5^2 + 6(5) = 25 + 30 = 55[/tex]

The rate of change is:

[tex]A = \frac{f(7) - f(5)}{7 - 5} = \frac{91 - 55}{2} = 18[/tex]

The average rate of change of the function in this interval is of 18.

The rate of change of a function over a given interval is required.

The average rate of change is 18

The given function is

[tex]f(x)=x^2+6x[/tex]

The interval is between [tex]x=5[/tex] to [tex]x=7[/tex]

Finding the corresponding [tex]y[/tex] values

[tex]y=5^2+6\times 5=55[/tex]

[tex]y=7^2+6\times 7=91[/tex]

The two points are

[tex](5,55),(7,91)[/tex]

The slope is

[tex]m=\dfrac{\Delta y}{\Delta x}\\\Rightarrow m=\dfrac{91-55}{7-5}\\\Rightarrow m=18[/tex]

Answer:

x=14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−1/5(x−4)=−2

(−1/5)(x)+(−1/5)(−4)=−2(Distribute)

−1/5x+4/5=−2

Step 2: Subtract 4/5 from both sides.

−1/5x+4/5−4/5=−2−4/5

−1/5x=−14/5

Step 3: Multiply both sides by 5/(-1).

(5/−1)*(−1/5x)=(5/−1)*(−14/5)
