Pls help me I really need to pass

Given:

[tex]y=f(x)[/tex]

[tex]f(x)=\dfrac{1}{2}x-3[/tex]

To find:

The input when the output is – 3.

Solution:

We have,

[tex]f(x)=\dfrac{1}{2}x-3[/tex]

Substituting [tex]f(x)=y[/tex], we get

[tex]y=\dfrac{1}{2}x-3[/tex]               ...(i)

We need to find the input when the output is – 3. It means, we have to find the value of x when [tex]y=-3[/tex].

Putting [tex]y=-3[/tex] in (i), we get

[tex]-3=\dfrac{1}{2}x-3[/tex]

[tex]-3+3=\dfrac{1}{2}x[/tex]

[tex]0=\dfrac{1}{2}x[/tex]

Multiply both sides by 2.

[tex]0=x[/tex]

Therefore, the input is 0 when the output is -3.

Answer:

57

Step-by-step explanation:

90 - 40% = 57

Answer:

The shoes would be $57

Step-by-step explanation:

To calculate percentage you use the equation:

P% x N = A

Before we use it we convert the number 40 into the tenths place of a decimal, 0.40.

Now we use it!

.40 x 95 = 38

38 would be 40%, so we remove it from the last total aka 95

95 - 38 = 57

Answer:

68% of races will his finishing time be between 79.5 and 82.5 seconds

Step-by-step explanation:

Mean time = 81 seconds

Standard deviation = 1.5 seconds

According to the empirical rule : 68%, 95%, 99% lies within 1, 2, and 3 standard deviations of the mean respectively.

Hence, for a finishing time between : 79.5 and 82.5

79.5 = 81 - 1.5 (1 standard deviation to the left of the mean)

82.5 = 81 + 1.5 (1 standard deviation to the right of the mean)

Hence,

79.5 and 82.5 lies within 1 standard deviation from the mean and it is Hence has a percentage of 68%

Your answer is C

Step-by-step explanation:

The definition of similarity is when one shape can become another after a resize, flip, slide or turn.

If you multiply AD, which is 6, by 1.5 you get 9. Which is the length AC.

If you multiply AE, which is 10, by 1.5 you get 15. Which is the length of AB.

Both triangles share angle A, so that leaves you with SAS Similarity.

Answer:

85 cm²

Step-by-step explanation:

Solve the area of the Rectangle:

A = bh

10 × 6 = 60 cm²

Solve the area of the Triangle:

A = bh × 1/2

10 × 5 = 50

50 × 1/2 = 25 cm²

Add the 2 areas together:

First, write statements! Then find out the operation. Very simple!

Number of burritos Chloe ate: 34

Number of burritos Lucy ate: 3

Number of burritos Chole ate more that Lucy: 34-3= 31

= Chloe ate 31 burritos more that Lucy.

Assuming the dark gray area is a straight line, the whole thing should add up to 180*. If we have our 180*, minus 79*, you'll have 101*. BUT, we also have to divide that by two to get our x answer, so the value of x would be 50.5*.

Answer:

b. 366 square inches

Step-by-step explanation:

The area of a triangle is 1/2×Base×Height. There are 2 pairs of identical triangles so you multiply each equation by 2.

2×(1/2×10×12) = 120 in²

2×(1/2×18×12) = 216 in²

120 in² + 216 in² = 336 in²

Answer:

336 square units

Step-by-step explanation:

Generally, to find the area of the given quadrilateral (which is presumably a kite), one uses the following formula,

[tex]\frac{(base)*(hieght)}{2}[/tex]

In this picture, one can see that the diagonals (dotted lines that connect opposite corners) are given, but their measurements are split up as per the segments they are divided into. In order to find the lengths of each diagonal, add up the two parts. To find the area of the figure, substitute the results into the given formula to find the area,

[tex]12+12=24\\\\10 + 18 = 28[/tex]

Substitute,

[tex]\frac{24*28}{2}\\\\=\frac{672}{2}\\\\=336[/tex]

Answer:

83 is still the mode

Step-by-step explanation:

The maximum possible value for the new mode is 83.

The data value that is repeated the most in the data set is called the mode of the given data set.

Given is that Mrs. Joyce calculated the class mode on her latest test. 18 students took it and the mode was 83. Three days later the four absent kids made it up and scored 77, 83, 68, and 80.

Initially, the mode of the class of 18 students is 83. This means that most of the students scored the 83 marks in the test. After four students took the test, the maximum probability that the mode will remain 83 is the highest. Also, one of the four numbers scored 83 itself.

Therefore, the maximum possible value for the new mode is 83.

Answer:

  B.  8.625 ft²

Step-by-step explanation:

The total area is the sum of the areas of the two rectangular sections and the area of the triangular section. The area formulas are ...

  A = LW . . . rectangle

  A = 1/2bh . . . triangle

Here, the dimensions are such that we can simplify the problem a bit

  total area = (1.5)(2.5) +1/2(1.5)(1.5) + (1.5)(2.5)

  = (1.5)(2.5 + 1.5/2 + 2.5)

  = (1.5)(5.75) = 8.625 . . . . . ft²

Answer: 72

Step-by-step explanation:

The formula for the area of a triangle is l * w / 2. In this case, the area of one triangle is 12, because 3*8=24/2=12. There are two triangles, so the combined area = 24. The area of the square is 48 because 6 * 8 = 48. Add it up, it makes 72.

Answer:

m<1 = 118

Step-by-step explanation:

The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that

(28) + (90) = m<1

Remember, a box around an angle signifies that its measure is (90) degrees.

Solve this problem by performing the operation,

118 = m<1
