what is the answer pls help

Answer:  (x,y) = (-1, 1)

This means that x = -1 and y = 1

========================================================

Explanation:

The first equation says that y is the same as 2x+3

That allows us to substitute y for 2x+3 in the second equation like so:

2x+5y = 3

2x+5( y ) = 3

2x + 5(2x+3) = 3 .... y replaced with 2x+3

2x+10x+15 = 3

12x+15 = 3

12x = 3-15

12x = -12

x = -12/12

x = -1

Then we'll substitute this into the first equation to find y

y = 2x+3

y = 2(-1) + 3 .... x replaced with -1

y = -2+3

y = 1

Together x = -1 and y = 1 pair up to form the ordered pair solution (x,y) = (-1,1)

If you were to graph y = 2x+3 and 2x+5y=3 on the same xy grid, then you should see that the two lines intersect at the location (-1,1). This is a visual way to determine the solution quickly through use of a graphing calculator.

Answer:

[tex]B)~g(x)=(2x)^{2}[/tex]

Step-by-step explanation:

g(1)=(2(1))²

= 2²

=4

g(x)= (2x)²

-----------------------

hope it helps...

have a great day!!

If the given function is f(x)=x², the value of g(x) will be (2x)².

Each value in the domain is connected to exactly one value in the range according to the function, which is described as a specific form of relationship. They have a predetermined range and domain.

It is given that the coordinate values are (1.4).

For the given function,

g(1)=(2(1))²

g(1)= 2²

g(1)=4

Since g(x)= (2x)² satisfies the given coordinate values it will be the obtained result.

Thus the obtained function will be g(x)= (2x)².

Answer:

The highest common factor of 10 and 18 is 2

Step-by-step explanation:

10:  1,10,2,5

18: 1,18,2,9,3,6,

Look which is common in both of these and both of them have 2 in common.

The HCF of 10 and 18 is 2.

To find the highest common factor (HCF) of 10 and 18, we can determine the largest number that divides evenly into both of them.

We can start by listing the factors of each number:

Factors of 10: 1, 2, 5, 10

Factors of 18: 1, 2, 3, 6, 9, 18

From the lists, we can see that the common factors of 10 and 18 are 1 and 2.

To find the HCF, we select the largest common factor, which is 2. Therefore, the HCF of 10 and 18 is 2.

The HCF represents the largest number that divides evenly into both given numbers, without leaving any remainder. In this case, 2 is the highest common factor, as it is the largest number that can divide both 10 and 18 without leaving any remainder.

Answer:

solution of what ? you mean the crossing point of both lines ?

that is (6,1) as the graph shows

Step-by-step explanation:

you can see x=6 and y=1.

that is then the point (6,1).

we could also define the equations of both lines and then calculate the value of x, where both equations deliver the same (y) value.

but for that we would need to get the (x,y) coordinates of the 4 marked points in the same way we got them for the crossing point already. waste of time and effort.

Answer:

26m

Step-by-step explanation:

The value of the opposite side (height of the flagpole) is to be determined given the angle and the value of the adjacent side(horizontal distance )

We would use tan 18 to determine the value of the missing side

tan 18 = opposite / adjacent

0.3249 = opposite / 80

0.3249 x 80 = 26m

Step-by-step explanation:

Raul ordered 1 small photo enlargement and 4 medium photo enlargements for $29. Patricia ordered 5 small photo enlargements and 2 medium photo enlargments for $28. determine the price of the small photo enlargements and medium photo enlargments

two equations can be derived from the question

s + 4m  = 29 equation 1

5s + 2m = 28 equation 2

where

s = small photo enlargements

m = medium photo enlargements

multiply equation 1 by 5

5s + 20m = 145 equation 3

subtract equation 2 from 3

18m = 117

m = 6.5

substitute for m in equation 1

s = 29 - (4 x 6.5)

s = 3

Answer:

B. The average high temperature in Death Valley was greater than the average in Boise

C. The variation of high temperature in Death valley was about the same as the variation in Boise

Step-by-step explanation:

Step 1: In a normal distribution, about 95% of the values are ±2 standard deviations from the mean. ±2 standard deviation from the mean high temperature of Boise is 39.1 to 65.1. Therefore, option A is wrong

Step 2: The average temperature high temperature of each of the places isngiven by their mean high temperatures.

The mean high temperature in Boise, Idaho, was 52.1°F while the mean high temperature in Death Valley, California, was 81.9°F.

Difference between the mean high temperatures is (81.9 - 52.1) = 29.8°F

Therefore, the average high temperature in Death Valley was greater than the average in Boise. Option B is correct.

Step 3: Standard deviation measures how spread out data is. It is a measure of variation of data.

The standard deviation of the high temperature in Boise, Idaho was 6.5° F, while the standard deviation of the high temperature in Death Valley, California was 6.4° F. This two values are about the same. Therefore, option C is correct.

Step 4: In a normal distribution, about 68% of the values are ±1 standard deviations from the mean. ±1 standard deviation from the mean high temperature of Death Valley is 75.5 to 88.3. Therefore, option D is wrong

Step 5: In a normal distribution, about 99.7% of the values are ±3 standard deviations from the mean. ±3 standard deviation from the mean high temperature of Boise is 32.6 to 71.6. Therefore, option E is wrong

Answer:

2571.14 m^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The diameter is 17 so the radius is 1/2 of the diameter or 17/2 =8.5

V = 4/3 (3.14) (8.5)^3

 = 2571.13666

Rounding to the nearest hundredth

 = 2571.14 m^3

=================================================

Work Shown:

V = (4/3)*pi*r^3

V = (4/3)*3.14*(8.5)^3

V = 2571.13666666667 which is approximate

V = 2571.14
