Answer:

y = 2x + 1

Step-by-step explanation:

Hope this helps!

Answer:

y = -2x - 5

Step-by-step explanation:

First rewrite the second equation into y = mx + b format:

x - 2y = 14  

2y = x - 14

y = x/2 - 14/2 (Divide both sides by 2)

y = 1/2x - 7

A line perpendicular to another has the negative reciprocal slope

So the slope of our first equation is -2. (Flip 1/2 = 2, then take the opposite)

Plug in the points (-1, -3) for the x and y coordinates.

x (x coordinate) = -1

y (y coordinate) = -3

slope (m) = -2

-3 = -1(-2) + b

-3 = 2 + b

-3 - 2 = b

b = -5

The equation of the line is y = -2x - 5. Hope this helps! :)

Answer:

y = -2x - 5  or 2x + y = -5

Step-by-step explanation:

Let's find the slope of the given line.  

-2y = -x + 14

y = 1/2(x) -7

m = 1/2

The slope of a line perpendicular is the negative reciprocal of 1/2, which is -2

Now use the point-slope form of a line

y + 3 = -2(x + 1)

y + 3 = -2x - 2

y = -2x - 5  or 2x + y = -5

Answer:

135

Step-by-step explanation:

Hello There!

Remember the exterior angle of a triangle rule:

An exterior angle of a triangle is equal to the sum of its opposite interior angles

so x = the sum of its opposite interior angles (58 and 77)

58 + 77=135

so x = 135

Answer: x=135°

Step-by-step explanation:

Angles in a triangle always add up to 180° so to find the corner of the missing side next to x you need to do 58+77=135 then do 180-135=45°

So then, now we have the angle inside the triangle, we can now work out what x is.

Angles on a straight line always add up to 180° so you do 180-45=135° so x=135°.

Answer:

5x + 25 <= 200

Step-by-step explanation:

When it says no more than 200, that means that 200 is the max, so what she spends has to be less than or equal to 200.

Answer:

200

Step-by-step explanation:this problem is actually very simple. a circle and a max measure of 360 so all you do is subtract 160 from 360 and there you go.     :)

Answer:

18

Step-by-step explanation:

18/45 is equal to 40/100

I just divided 100 by 45 to find how much they multiplied the original fraction by to get 40/100

then I divided 40 by the number I got from the last equation and got 18

Answer:

The answer for it is 44.71

Answer:

x = 2

y = 5

Step-by-step explanation:

We can say:

7 corresponds to y

(3 + 7.5) corresponds to 7.5

Plus, we can write a ratio

[tex] \frac{7}{y} = \frac{3 + 7.5}{7.5} [/tex]

[tex] \frac{7}{y} = \frac{10.5}{7.5} [/tex]

Cross multiplying, we can solve for "y",

[tex] \frac{7}{y} = \frac{10.5}{7.5} [/tex]

[tex] \frac{7}{y} = 7 \times 7.5[/tex]

y = 5

Again, using similarly, we can say:

(x + 5) corresponds to 5

(3 + 7.5 = 10.5) corresponds to 7.5

We can write a ratio:

[tex] \frac{x + 5}{5} = \frac{10.5}{7.5} [/tex]

Cross multiplying and with the help of a but algebra, we can solve for "x", shown below:

7.5( x + 5) = 5 x 10.5

7.5x + 37.5 = 52.5

7.5x = 15

x = 2

Answer:

132 green marbles

Step-by-step explanation:

green : purple

11 : 8

? : 96

first divide 96 by 8:

96 ÷ 8 = 12

this allows us to know how much it went up by

next, take 11 and multiply it by 12:

11 x 12 = 132

there are 132 green marbles

Answer:

The missing value = [tex]23\frac{1}{24}[/tex]

Step-by-step explanation:

Given - Equation: ? + 59 5/8= 82 2/3

To find - Explain (in words) what you would do to find the missing value in

              the equation. You do not find the missing number.

Proof -

Let the missing number = x

So, the equation becomes x + [tex]59\frac{5}{8}[/tex] = [tex]82\frac{2}{3}[/tex]

⇒x = [tex]82\frac{2}{3}[/tex] - [tex]59\frac{5}{8}[/tex]

     = [tex]\frac{248}{3} - \frac{477}{8}[/tex]

     = [tex]\frac{1984 - 1431}{24}[/tex]

     = [tex]\frac{553}{24}[/tex]

     = [tex]23\frac{1}{24}[/tex]

⇒x = [tex]23\frac{1}{24}[/tex]

∴ we get

The missing value = [tex]23\frac{1}{24}[/tex]

Explanation -

Here we have given the ? with addition of number that is equation to some number.

We just have to subtract the two numbers to find the missing value , as we do above.

Answer:

what was c?

Step-by-step explanation:

Answer:

1.) y = -6

2.) y = 5/3x - 7

3.) y = 5

4.) y = -3x + 1

5.) x = -3

Step-by-step explanation:

Answer:

1.) 49.5 mm ^2

2.) 183 in. ^ 2

Step-by-step explanation:

So for number one, it's a very irregular shape, but luckily, we can split it vertically! Into a triangle & a quadrilateral.

The area of the quadrilateral would be

6*7 = 42

The triangle is more difficult, because its not directly given, BUT, we do know that the height would have to be 6 minus 3, and the base would be 12 minus 7... So the equation is

[tex]A = \frac{1}{2} bh\\A = \frac{1}{2}(5)(3)\\A = 7.5[/tex]

Now, the rectangle and the triangle account for the total area in this case, when you add them, you get 49.5 mm ^2

~~~~~~~~

For the second, we have a trapezoid with a triangular cutout, the area of a trapezoid is defined as:

[tex]A = \frac{1}{2} (B1-B2) h[/tex]

Luckliy, none of the numbers of the bases, or height, are hidden. The height is 18, the larger base is 51, and the smaller is 24.

[tex]A = \frac{1}{2} (51-24)18\\A = 243[/tex]

So, the trapezoid area is 243 in ^2. But we aren't done, we still have the triangle! It will be easy though!

Remember, the formula for a triangle is half the base times the height. These numbers are directly given to us!

[tex]A = \frac{1}{2} (12)(9)\\A = 54[/tex]

Now, since the triangle is NOT SHADED, we subtract it's area from the trapezoid's...

[tex]243 - 54 = 183[/tex]

The area is 183 in. ^ 2

1)49.5mm ^2.

2)183 in ^2.

Step-by-step explanation:

So for number one it's a very iregular shape,but luckily ,we can slip it vertycally.

Answer:

140 feet squared

Step-by-step explanation:

Let's do this step by step. First, let's find the area of the rectangle, which is 8 times 10. It equals 80. Next, do the trangle. 6 times 10 is 60. So, 60 plus 80 equals 140.

Answer:

area of rectangle =L*B

8*10=80ft^2

area of triangle=1/2b*h

h is 8 ft

1/2*6*8

3*8

24ft^2

total area is 80+24

104ft^2

nearest tenth = 100 ft^2

Answer:

area is 804.2477193

Answer:

A. [tex]h(x) = (x+2)^{2}+5[/tex]

Step-by-step explanation:

First, we need to defined the two transformations required to derive [tex]h(x)[/tex].

Vertical translation

[tex]n(x) = m(x) +k[/tex], [tex]k \in \mathbb{R}[/tex] (1)

Where:

[tex]k > 0[/tex], upwards.

[tex]k < 0[/tex], downwards.

Horizontal translation

[tex]n(x) = g(x+k)[/tex], [tex]k\in \mathbb{R}[/tex] (2)

Where:

[tex]k > 0[/tex], leftwards.

[tex]k < 0[/tex], rightwards.

Let [tex]f(x) = x^{2}[/tex], if [tex]h(x)[/tex] is translated 2 units left and 5 units up, then we have the resulting expression:

[tex]h(x) = (x+2)^{2}+5[/tex] (3)

Hence, correct answer is A.
