can you plz answer this for me its graded

Answer:

2x + y = -7

Step-by-step explanation:

Standard form is Ax + By = C

A represents the coefficient with x

B represents the coefficient with y

C represents the constants

1 - Rewrite to make it easier to work it out

y - 3 = -2 ( x + 5 )

2 - Distribute

y - 3 = -2x - 10

3 - Get the variables on one side and the constants on the other

y - 3 = -2x - 10

+ 2x  + 2x

2x + y - 3 = -10

         + 3   + 3

2x + y = -7

Answer:

Not a function

Step-by-step explanation:

For 0 in the domain (input), there are two possible values in the output (range). This goes against the definition of a function, where every element in the domain must have only one value in the range.

Answer:

A

Step-by-step explanation:

Use the equation given for sin

Answer:

38

Step-by-step explanation:

if there are bars around it its automatically positive even if it was -38 the absolute would still be 38.

Answer: 38

Step-by-step explanation: The absolute value of a number

is that number's distance from zero on a number line.

Since 38 is 38 units from zero, the absolute value of 38 is just 38.

The temperature, in December is 47 °F

Step-by-step explanation:

The given data for the temperature are;

Month             [tex]{}[/tex]         Temp (°F)

April                   [tex]{}[/tex]          59

May               [tex]{}[/tex]               68

June             [tex]{}[/tex]                71

July                  [tex]{}[/tex]             78

August              [tex]{}[/tex]            74

Let x represent the month, and f(x) = y represent the temperature, we have;

y = a·x² + b·x + c

When x = 1, we have, f(1) = a·1² + b·1 + c = 59

f(1) = a + b + c = 59...(1)

When x = 2, we have, f(2) = a·2² + b·2 + c = 68

f(2) = 4·a + 2·b + c = 68...(2)

When x = 3, we have, f(3) = a·3² + b·3 + c = 71

f(3) = 9·a + 3·b + c = 71...(3)

When x = 4, we have, f(4) = a·4² + b·4 + c = 78

f(3) = 16·a + 4·b + c = 78...(4)

When x = 5, we have, f(5) = a·5² + b·5 + c = 74

f(3) = 25·a + 5·b + c = 74...(5)

Subtracting equation (3) from equation (5), we get;

25·a + 5·b + c - (9·a + 3·b + c) = 74 - 71

16·a + 2·b = 3...(6)

Subtracting equation (1) from equation (2), we get;

4·a + 2·b + c - (a + b + c) = 68 - 59

3·a + b = 9...(7)

Multiply equation (7) by 2 and substract from equation (6) gives;

16·a + 2·b - 2 × (3·a + b) = 3 - 2 × 9

16·a + 2·b - 6·a - 2·b = 3 - 2 × 9

16·a - 6·a + 2·b  - 2·b = 3 - 2 × 9 = -15

10·a = -15

a = -15/10 = -1.5

a = -1.5

From, 3·a + b = 9, we have;

3 × (-1.5) + b = 9

b = 9 + 4.5 =13.5

b = 13.5

From, a + b + c = 59, we have;

-1.5 + 13.5 + c = 59

c = 59 - (-1.5 + 13.5) = 47

c = 47

The quadratic equation becomes, y = a·x² + b·x + c = -1.5·x² + 13.5·x + 47

f(x) = y = -1.5·x² + 13.5·x + 47

For December, we have, x = 9, and f(x) = -1.5×9² + 13.5×9 + 47 = 47

The temperature, in December = 47 °F

Answer:

Marissa.

Step-by-step explanation:

To find perpendicular slope you basically take the slope of the given line and reverse whatever sign it had previously. (If it was negative, it would become positive. If it was positive it would become negative.)

By doing -A/B it make the previous slope negative.

Brandon only flipped the fraction which would just result in the slope being slightly steeper, or in this case, less steep than the previous line, rather than making it perpendicular.

Answer:

x=46°

Step-by-step explanation:

base angles in an isosceles triangle are equal

180-88 = 92°

92/2=46°

46 + 46 +88 = 180

Answer:

A triangle always will equal 180° degrees. Each other angle equals 46°.

Step-by-step explanation:

180° - 88° = 92°

92 ÷ 2 = 46°

I got it right on the question.

Answer:

The linear equality y>x+1 is the right answer.

Answer:

The linear equality y>x+1 is the right answer.

Step-by-step explanation:

Answer:

The answer is c definitely

Answer:

C. x + 8 = 3

Step-by-step explanation:

x + 8 = 3

x + 8 - 8 = 3 - 8 ( so do the same thing you do on both the left and right side )

x = -5

So C is correct but you can always say 3 - 8 to figure out that the answer in c is the right one.

Answer:

B. 500

Step-by-step explanation:

the scale only measures increments of 1,000 pounds, e.g. its scale is 0 pounds, 1,000 pounds, 2,000 pounds, 3,000 pounds, etc.

What happens if something weighs exactly 1,500 pounds (or 500, 2500, 3500, etc)? The scale will measure either 1,000 or 2,000 pounds, so the maximum margin of error is ± 500 pounds.
