Answer:

X=2, y=8

Step-by-step explanation:

Y=-x+10 equation 1

y=2x+4 equation 2

-x+10=2x+4. Substitute y of first equation into 2nd equation

-x-2x+10=4

-3x=4-10

-3x=-6

x=2

solve for y by inserting x value into either equation

y=-x+10

y=-2+10

y=8

check answer

y=2x+4

8=2(2)+4

8=4+4

8=8

Answer:

[tex] \rm \displaystyle A_{ \text{triangle}} = \frac{147 \sqrt{7} }{2 } \quad \text{or} \quad 73.5 \sqrt{7} [/tex]

Step-by-step explanation:

we have a right angle triangle composited in a semi-circle we want to figure out the area of the triangle

in order to do so we need to figure out the adjacent side (height AB)

since the given triangle is a right angle triangle we can consider Pythagoras theorem given by

[tex] \displaystyle {a}^{2} + {b}^{2} = {c}^{2} [/tex]

given that,a=21 and c=28

substitute:

[tex] \displaystyle {21}^{2} + {b}^{2} = {28}^{2} [/tex]

move left hand side expression to right hand side and change its sign:

[tex] \displaystyle {b}^{2} = {28}^{2} - {21}^{2} [/tex]

square root both sides:

[tex] \displaystyle {b}^{} = \sqrt{{28}^{2} - {21}^{2} }[/tex]

use algebraic indentity:

[tex] \rm \displaystyle {b}^{} = \sqrt{({28}^{} + 21) (28 - {21}^{})}[/tex]

simplify:

[tex] \rm \displaystyle {b}^{} = \sqrt{({49}) ( 7)}[/tex]

use redical property:

[tex] \rm \displaystyle {b}^{} = 7 \sqrt{ 7}[/tex]

now to figure out the area we can consider the following formula:

[tex] \displaystyle A_{ \text{triangle}} = \frac{1}{2} bh[/tex]

remember that,h=AB=7√7 and b=BC=21 thus substitute:

[tex] \displaystyle A_{ \text{triangle}} = \frac{1}{2} \times 21 \times 7 \sqrt{7} [/tex]

simplify multiplication:

[tex] \rm \displaystyle A_{ \text{triangle}} = \frac{147 \sqrt{7} }{2 } \quad \text{or} \quad 73.5 \sqrt{7} [/tex]

hence,

the area of the triangle is 194 (approximately)

Answer:

(1,000 * (100 + 12))/100 = 1,120 - 1,000 = 120 turtles/ per year

Step-by-step explanation:

The exponential function which can be use to identify the monthly growth is,

⇒ y = 1000 (1.12)¹²ⁿ

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

That's population of turtles in a lake is estimated at 1,000.

And,  The population projected to increase 12% per year.

Hence, The exponential function which can be use to identify the monthly growth is,

⇒ y = 1000 (1 + 12/100)¹²ⁿ

⇒ y = 1000 (1 + 0.12)¹²ⁿ

⇒ y = 1000 (1.12)¹²ⁿ

Thus, The exponential function which can be use to identify the monthly growth is,

⇒ y = 1000 (1.12)¹²ⁿ

Answer:

y+1=-3(x+2)

Step-by-step explanation:

point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope

we are given a point (-2, -1) and a slope of -3

all we really need to do is substitute the given into the formula

remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers

substitute -2 as x, -1 as y and -3 as m

y--1=-3(x--2)

we can simplify this equation:

y+1=-3(x+2)

A study with a sample that is very different from the population is biased

The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.

Population density = number of people / the area they occupy

Given data ,

A study with a sample that is very different from the population is J. biased.

In statistical terms, bias refers to any systematic error or deviation from the true value that can occur in a study. When a study is biased, the results may not be representative of the population and may not be generalized other settings.

Results from a research may be skewed if the sample chosen is considerably different from the population. Both experimental and observational research may experience this. As a result, alternatives F and G do not offer sufficient details to assess the study's objectivity.

Answer:

Step-by-step explanation:

Answer:

x = -2

Step-by-step explanation:

30=-5(6x+6)

step 1 distribute the -5

-5 * 6x = -30x

-5 * 6 = -30

we now have 30 = -30x - 30

step 2 add 30 to each side

30 + 30 = 60

-30 + 30 cancels out

we now have 60 = -30x

step 3 divide each side by -30

-30x/-30 = x

60 / -30 = -2

we're left with x = -2

Answer:

Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable. The calculation for ROC is simple in that it takes the current value of a stock or index and divides it by the value from an earlier period.

Answer:A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. rate of change=change in ychange in x. Rates of change can be positive or negative.

Answer:

Step-by-step explanation:

The triangle equals 180 degrees the two measurements we already have is 90 degrees (the right angle) and 64 degrees.

90+64=154 and 180-154=26.

So 26 is your answer because 90+64+26=180
