Answer:

A

Step-by-step explanation:

x= 1 2/3, y=4 2/3

y=4(1 2/3)-2.    y=4 2/3

y=1 2/3+3        y=4 2/3

and that make the answer going to be A. Also other answer didn't work so yet. Then, A should be the right answer!

Hope this help!

A. x = [tex]\frac{5}{3}[/tex] or [tex]1\frac{2}{3}[/tex]  and y = [tex]\frac{14}{3}[/tex] or [tex]4\frac{2}{3}[/tex]

y = 4x - 2  ; y = x + 3

1. UNDERSTAND what you are given.

2. SUBSTITUTION METHOD means you replace one of the variables in terms of the other to start solving.

4x - 2 = x + 3 (write eq.)

3x - 2 = 3 (combine like terms: part 1)

3x = 5 (combine like terms: part 2)

x = [tex]\frac{5}{3}[/tex] or [tex]1\frac{2}{3}[/tex] (inverse operations: division)

3. PLUG IN VALUE FOR X to solve for y. Pick the simpler equation.

y = x + 3 (pick an original equation, either will work)

y  = [tex]\frac{5}{3}[/tex] + 3

y = [tex]\frac{5}{3}[/tex] + [tex]\frac{9}{3}[/tex]

y = [tex]\frac{14}{3}[/tex] or [tex]4\frac{2}{3}[/tex]

Answer:

14

Step-by-step explanation:

The two points on y=5 are (4,5) and (10,5), which can be deducted if you draw a picture with (7,1) and y=5 on it. A vertical line through 7,1 and the line to "some" points on y=5 left and right of it have lengths 4 and 5 respectively.

Then I realized these were two 3,4,5 triangles! So the x coordinates must be at 7-3=4 and 7+3=10 respectively!

The sum of 4 and 10 is 14.

edit: seems to me the sum is 14 regardless of the length of 5??

Answer:

Solution,

[tex]10y -6y - (3y - 4y) \\ = 10y - 6y - 3y + 4y \\ = 10y + 4y - 6y - 3y \\ = 14y - 6y - 3y \\ = 8y - 3y \\ = 5y[/tex]

Hope this helps.

                             =  [tex]\frac{7531}{91}[/tex]  =  82.76

Now, the standard deviation of the data is given by;

          Standard deviation, S.D.  =  [tex]\sqrt{\frac{\sum f(X-\bar X)^{2} }{\sum f-1}}[/tex]

                                                     =  [tex]\sqrt{\frac{11580.68}{91-1}}[/tex]

                                                     =  11.34

Hence, the standard deviation of the given data is 11.34.

Answer:

Since the Crayola box contains more markers that should be the right choice.

Step-by-step explanation:

In order to calculate the number of markers each box contains, we need to divide the width of the box by the width of the markers for each box and compare their numbers. Since the lengths are given in mixed fractions, we will first convert them to pure fractions.

For Crayola:

[tex]\text{box width} = 2 + \frac{3}{4} = \frac{8}{4} + \frac{3}{4} = \frac{11}{4} \text{ inches}[/tex]

[tex]n = \frac{\frac{11}{4}}{\frac{1}{4}} = 11[/tex]

For the Sharpie:

[tex]\text{box width} = 3 + \frac{3}{5} = \frac{15}{5} + \frac{3}{5} = \frac{18}{5} \text{ inches}[/tex]

[tex]n = \frac{\frac{18}{5}}{\frac{4}{10}} = \frac{18*10}{5*4} = \frac{180}{20} = 9[/tex]

Since the Crayola box contains more markers that should be the right choice.

Parallel lines have same slope.

Answer:

Step-by-step explanation:

Let's solve (4y - 3)^2 = 72 for y.  To do this, take the square root of both sides.  This yields:

4y - 3 = ±√72 = ±√(36·2) = ±6√2

Then 4y = 3 ±6√2, or

       3 ± 6√2

y = ----------------

             4

The required solution of quadratic equation is y = (3±6√2)/4. Option A is correct.

Solution of the quadratic equation (4y - 3)2 = 72 to be determine.

Quadratic equation are the equation having maximum power 2.

Here,
(4y - 3)² = 72
4y-3 = ±√72
4y = ±√72 +3
y = (3 ± 6√2)/4

Thus, The required solution of quadratic equation is y = (3±6√2)/4.

Answer:

C,110°

Step-by-step explanation:

when the angle on circumference=50°

then the angle at center=2×50=100°

other angles of this triangle are equal and each=1/2(180-100)=1/2×80=40

so angle of quadrilateral=30+40=70°

as opposite angles of a cyclic quadrilateral are supplementary.

so y+70=180

y=180-70=110°

Answer:

43.6 amp

Step-by-step explanation:

Given

A 40 amp fuse carries a temporary 9 % current overload.

9% current overload means that whatever will be the normal current carrying capacity of fuse, during overload it carries 9% more than that.

Current carrying capacity of fuse is 40 amp.

during overload it carries 9% more

over load current = 9% of 40 amp  = 9/100 *40 = 3.6 amp

total current flowing through fuse during overload = 40 amp + 3.6 amp

                                           = 43.6 amp (answer)

Answer:

35 cuts or 36 parts

The lumberjack cuts 7 numbers of the log on the painted lines.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Let length of the log on the painted lines = 72 units

Pedro wants the log cut into 24 equal parts,

⇒ 72/24 = 3 units

John wants the log cut into 18 equal parts,

⇒ 72/18 = 4 units

Hence, the lumberjack cuts 7 numbers of the log on the painted lines.

Answer:

(1,1) (2,1) (2,3) (1,3) They form a rectangle because there are two pairs of parallel sides.

:)

Answer:

The number of distinct triangles that can be drawn using the dots = 6

Step-by-step explanation:

The parameters given are;

Two rows of three evenly spaced dots

To form a triangle, two dots will be selected from 1 row while the third dot will be selected from the other row

The number of ways of selecting the dots are therefore;

₃C₂ × ₃C₁ = 3 × 3 = 9 triangles

The same procedure can be done from the top row to give another 9 triangles

Which gives the total number of triangles = 18 triangles

The number of distinct triangles are found as follows;

Given that triangles obtained from the top row are similar to those of the bottom row, we reduce the range from which the distinct triangles can be found to 19 - 9 = 9 triangles

Of the 9 triangles formed by one dot on top and two dots on the bottom, the two adjacent dots of the three dots which are on the left and on the right of the lower row of dots, form the same three triangles with the three dots on the top row

Therefore, since there are 3 sets of two dots forming 9 triangles, each pair of dots can form 3 triangles, and as mentioned, 2 pairs of dots of the 3 pairs form the same triangles making the distinct triangle = 9 - 3 = 6.

Answer:

24 units.

Step-by-step explanation:

we can use  concept of Thales intercept theorem in this problem

according to this theorem, if  there are n lines parallel to each then and two transverse line drawn such that they intersect the three parallel line given the problem, then the parallel line divides the transverse line equal proportion.

For this problem

For the line having length 45, one of the length is 25 units,

then other length will be 45-25 = 20 unit

Now using Thales intercept theorem

30/? = 25/20

30/? = 5/4

? = 30*4/5 = 24

Thus, missing side length will be 24 units.

1/4+m=2/3

Step-by-step explanation:

The total rectangle is equal to 2/3 as shown on the bottom rectangle.

1/4 and m fit into that same rectangle meaning that 1/4+m=2/3

The equation to represent the image is 1/4 + m= 2/3.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

1/4 and m

and, total = 2/3

So, we add together 1/4 and m then we get 2/3

Then, the mathematical expression is

1/4 + m= 2/3
