Answer:

v=−5

Step-by-step explanation:

2v + 18 = 16 - 4(v + 7)

2v+18=16−4(v+7)

2v+18=16+(−4)(v)+(−4)(7)(Distribute)

2v+18=16+−4v+−28

2v+18=(−4v)+(16+−28)(Combine Like Terms)

2v+18=−4v+−12

2v+18=−4v−12

Add 4v to both sides.

2v+18+4v=−4v−12+4v

6v+18=−12

Subtract 18 from both sides.

6v+18−18=−12−18

6v=−30

Divide both sides by 6.

6v /6 = −30 /6

v=−5

Answer:

[tex]n + d = 368[/tex]

[tex]0.05n + 0.10d = 28.40[/tex]

Step-by-step explanation:

Given

[tex]Total = 368[/tex]

[tex]Value = \$28.40[/tex]

Required

Determine the linear equations to represent the scenario

Represent nickel with n and dimes with d

So, the total is:

[tex]n + d = 368[/tex]

[tex]1\ nickel = \$0.05[/tex]

[tex]1\ dime = \$0.10[/tex]

So, the value is:

[tex]0.05n + 0.10d = 28.40[/tex]

Hence, the linear equations are:

[tex]n + d = 368[/tex]

[tex]0.05n + 0.10d = 28.40[/tex]

The system of linear equations and solution can be used to represent the number of nickels and dimes Matthew has in his collection is n + d = 368 0.05n + 0.1d=28.4  168 nickels and 200 dimes.

Given that,

Based on the above information, the calculation is as follows:

n + d = 368

So,

d = 368 - n

And,

0.05n + 0.10d = 28.40

0.05n + 0.10(368 - n) = 28.40

0.05n + 36.8 - 0.10n = 28.40

0.05n = 8.4

n = 168

So, d = 368 - 168

= 200

Therefore we can conclude that the correct option is A.

Answer:

y = 8

Step-by-step explanation:

x = 9 is a vertical line, so any perpendicular to it is horizontal.

Horizontal line passing through (-1/9,8): y = 8

Answer: Y=120 Z=20

Step-by-step explanation: this ones a little harder so im not too confident in these answers.. but hopefully they are also correct.

Answer:

y=120 and z=20

Step-by-step explanation:

bringing (5z-40)° in their vertically opposite side

5z-40=60[being the pair of corresponding angle]

or, 5z=60+40

or, 5z=100

z=20

again,

5z-40+y=180[sum of straight angle]

or, 5×20-40+y=180

or, 100-40+y=180

or, y=180-60

y=120

Answer:

x = 5

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

x+4−3x=3x−6−3x

−2x+4=−6

Step 2: Subtract 4 from both sides.

−2x+4−4=−6−4

−2x=−10

Step 3: Divide both sides by -2.

−2x /−2 = −10 /−2

x = 5

[tex]m=1[/tex]

Step-by-step explanation:

Slope can be calculated using following formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]  ----------- (1)

Here

[tex](x_1, y_1)=(1, 1) \ \ and \ \ (x_2, y_2) = (2, 2)[/tex]

Substitute values in equation (1)

[tex]m=\frac{2-1}{2-1}[/tex]

[tex]m=1[/tex]

Answer:

slope = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Calculate slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1) ← 2 points on the line

m = [tex]\frac{1-0}{3-0}[/tex] = [tex]\frac{1}{3}[/tex]

Answer:

4

Step-by-step explanation:

they all equal to 4

4 x 12 = 48

4 x 7 = 28

4 x 11= 44

therefor its 4

The greatest common factor of 48, 28, and 44 is 4.

The greatest common factor for 42, 28, and 44 is to be determined.

Factors can be defined by splitting the value into multipliable values.

Here,
Factor of 42 = 2,4,6,7
Factor of 28 = 2,4,7
Factor for 44 = 2,4,11
So, the greatest common factor is 4

Thus, the greatest common factor of 48, 28, and 44 is 4.

Answer:

No, it is not.

Step-by-step explanation:

I mapped the equation with a graphing calculator. It is not linear.

Pls mark brainliest. Thanks!

Step-by-step explanation:

The quadratic equation is x² + (p - 5)x + 2q = 0.

By Vieta's Formula,

we have SOR = -b/a and POR = c/a.

=> (-3) + (6) = -(p - 5) and (-3)(6) = 2q.

=> 3 = 5 - p and -18 = 2q

Hence, p = 2 and q = -9.

Alternate Method:

We have (x + 3) and (x - 6) as factors of the quadratic equation x² + (p - 5)x + 2q = 0.

=> (x + 3)(x - 6) = x² - 3x - 18.

By Comparing Coefficients,

(p - 5) = -3 and 2q = 18.

Hence p = 2 and q = -9.

Step-by-step explanation:

You have to prove the triangle congruent by SSS (side side side), SAS (side angle side), ASA (angle side angle), AAS (angle angle side), and HL (hypotenuse leg). I proved this triangle by SAS because they already told us that < A and < D are congruent and that line BC is congruent to line EC. So I just had to prove that <ACB and <DCE are congruent, and since they are vertical angles they have to be congruent.

Answer:

The slope of the function graphed is less than the linear function that has an x-intercept of 1 and a y-intercept of -2.

Step-by-step explanation:

It is given that x-intercept is 1 and y-intercept is -2.

Now, the coordinate of the point is (1,0) and (0,-2).

We know that,

Slope = [tex]\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]S_1=\dfrac{-2-0}{0-1}[/tex]

[tex]S_1 = \dfrac{-2}{-1}[/tex]

[tex]S_1=2[/tex]

Now, Slope of the graph given

Co-ordinate is (-5,0) and (1,2).

Using the formula of slope

[tex]S_2 = \dfrac{2-0}{1-(-1)}[/tex]

[tex]S_2 = \dfrac{2}{1+1}[/tex]

[tex]S_2 = \dfrac{2}{2}[/tex]

[tex]S_2 =1[/tex]

Now, [tex]S_1>S_2[/tex]

Hence, the slope of function graphed is less than linear function that has an x-intercept of 1 and a y-intercept of -2.
