Answer:

y= -x+5

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Let's find the value of m first.

The product of the gradients of 2 perpendicular line is -1.

Given line: y= x -10

Gradient of given line= 1

m(1)= -1

m= -1

y= -x+c

To find c, substitute a coordinate.

when y= -5, x=10,

-5= -10 +c

c= 10-5 (+10 on both sides)

c=5 (simplify)

Thus, the equation is y= -x +5.

5x1.29=6.45

29.97+6.45=36.47

Answer:

36,42

Step-by-step explanation:

3 x 9,99 = 29,97

5 x 1,29 = 6, 45

29,95 + 6,45 = 36,42

Answer:

3.

Step-by-step explanation:

3m^2-3n^2= 3(m^2-n^2) = 3 (m+n)(m-n)

6m-6n= 6 (m-n)

3(m+n)~(m-n)~/6~(m-n)~ = (m+n)/2

The scale factor which segment AB was dilated by is 4

The graph that completes the question is added as an attachment

From the attached graph, we have the following coordinates

A = (0, 2)

B = (2, 3)

The coordinates of the image of dilation are given as:

A' = (0, 8)

B' = (8, 12)

Divide the coordinates of A' by A

So, we have:

Scale factor = A'/A

This gives

Scale factor = (0, 8)/(0, 2)

Evaluate the quotient

Scale factor = 4

Hence, the scale factor which segment AB was dilated by is 4

Answer: 11/3 as a mixed number is 3 2/3

Answer:

3 2/3 inches of snow

Step-by-step explanation:

Your denominator is 3. Use the denominator to see how many times it goes into the numerator.

Knowing 3*3 = 9, then 3 goes into 11 three times

subtract 9 from 11 : 11 - 9 = 2

You are given a remainder of 2

Your whole number is three, and because you have 2 remaining from the 11, the 2 becomes 2/3

Answer: 3 2/3  inches of snow

Answer:

Option A.

Step-by-step explanation:

If a system of equations has two equations and the graph of both equations intersect at point, then the intersection point is the solution of the system of equations.

The given equations are

[tex]x+9y=5[/tex]

[tex]4x+15y=-1[/tex]

It is given that the graph of both lines intersect each other at point (-4,1).

It means, (-4,1) is a solution to the system of linear equations.

Therefore, the correct option is A.

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

10x +8 = 3(x-2)

Distribute

10x +8 = 3x-6

Subtract 3x from each side

10x+8-3x = 3x-6-3x

7x +8 = -6

Subtract 8 from each side

7x+8-8 = -6-8

7x = -14

Divide each side by 7

7x/7 = -14/7

x = -2

Answer:

10x + 8 = 3x - 6, 7x = -14

Step-by-step explanation:

10x + 8 = 3 ( x - 2 ) = 10x + 8 = 3x - 6

subtract 8 from both sides of the equation: 10x + 8 = 3x - 6

10x + 8 - 8 = 3x - 6 - 8

simplify

10x = 3x - 14

subtract 3x from both sides

10x - 3x = 3x - 14 - 3x

simplify

7x =  -14

divide both sides by 2

7x / 2 = -14 / 2

simplify

x = -2

103.5

Step-by-step explanation:

Answer:

y ≥ x - 2, and x + 2y < 4 ; Option C

Step-by-step explanation:

Consider the y - intercept and slope of 1 of these given lines,

[tex]y - intercept = ( 0, - 2 ) / - 2\\slope = 1 / 1 = 1[/tex]

From this we can formulate the equation of 1 line;

[tex]Take Equation In the Form - y = ax + b, a - slope, and , b - y intercept,\\y = ax + b, a = 1, b = - 2,\\Equation of Line 1 - y = x - 2[/tex]

Now consider the y - intercept and slope of the remaining line;

[tex]y - intercept = ( 0, 2 ) / 2\\slope = 1 / - 2 = - \frac{ 1 }{ 2 }[/tex]

This creates a line with the equation as such;

[tex]Take Equation In the Form - y = ax + b, a - slope, and , b - y intercept,\\y = ax + b, a = - 1 / 2, b = 2,\\Equation of Line 1 - y = - \frac{ 1 }{ 2 } x + 2, x + 2y = 4[/tex]

From this we see that the solution of the system is such;

Solution ; y ≥ x - 2, and x + 2y < 4 ; Option C

Answer:

35 inches

Step-by-step explanation:

The perimeter of a rectangle is given by

P = 2(l+w)

We know the perimeter and the length

84= 2 ( l+7)

Divide each side by 2

84/2 = 2/2 (l+7)

42 = (l+7)

Subtract 7 from each side

42-7 = l+7-7

35 = l

The length is 35 inches

Answer:

[tex]l = 35 \: \: inches[/tex]

Step-by-step explanation:

[tex]perimeter \\84 = w + w + l + l \\ 84 = 7 + 7 + 2l \\ 84 = 14 + 2l \\ 84 - 14 = 2l \\ 70 = 2l \\ \frac{70}{2} = \frac{2l}{2} \\ l = 35 \: \: inches[/tex]

Answer:

80°

Step-by-step explanation:

The angles can be written as 4x, 6x, and 8x. Since the sum of angles in a triangle is 180 degrees we can write:

4x + 6x + 8x = 180

18x = 180

x = 10 which means the largest angle (8x) = 8 * 10 = 80°

Im not really sure how to explain it but the number at the top of the ‘stem’ side has to be the smallest number and the bottom one is the biggest.

You then have to write out the numbers in the ‘leaf’ side by only putting one digit numbers in order from smallest to biggest.

the temperatures ordered from least to greatest

52, 53, 54, 54, 57, 62, 64, 69, 73, 73, 77, 78

the min is 52

the max is 78

median:

52, 53, 54, 54, 57, 62, 64, 69, 73, 73, 77, 78

(62+64)/2=126/2=63

thus the median is 63

now we don't include the median in finding the upper and lower quartile medians:

lower quartile median:

52, 53, 54, 54, 57, 62

54 (same #s no need to add up and divide by 2)

upper quartile median:

64, 69, 73, 73, 77, 78

Answer:

A

Step-by-step explanation:

Sorry for the late response but the previous 2 answers lacked an explanation.

The sample space of an experiment / trial is the range of all outcomes from that experiment / trial. In this case, the trial is spinning the spinner. You might think that the answer is D because those are all of the possible outcomes you might get when spinning the spinner, however, some of the outcomes are repeated. In a sample space, each element of the sample space set is different, therefore, the answer is {1, 2, 3, 4} which is A.

Answer:

The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the left) times the height,h.

Step-by-step explanation:

hope that make sense, i tried to find something that explained

Step-by-step explanation:

Surface area is found by adding up all the areas of the different figures. When there are multiple figures of the same dimensions, you can just multiply them by the number of their amount.

The areas you'll be using for the triangular prism are:

[tex]a = \frac{1}{2} bh[/tex]

and

[tex]a = lw[/tex]

since there are both rectangles and triangles in this figure.

Using the prism, then, it's time to make a formula.

[tex]2( \frac{1}{2} bh) + 2(lw) + lw[/tex]

I put a 2 in front of the triangle's area because there are 2 triangles in this prism.

There's a 2 in front of the side of the triangle's area (it's a rectangle) because it has two sides.

That last lw doesn't have a number on it because it's for the base, and this prism only has one base.

Now, use the dimensions that are given to you to substitute.

[tex]2( \frac{1}{2} )(14)(24) + 2(10)(25) + (10)(14) \\ 336 + 500 + 140 \\ 836 + 140 \\ 976[/tex]

So, 976cm^2 is your area.

[tex]976 {cm}^{2} [/tex]
