Answer:9 11/20

Step-by-step explanation:

Answer:

Simplifying 6p + 2(4 + -2p) = 3(p + 4) 6p + (4 * 2 + -2p * 2) = 3(p + 4) 6p + (8 + -4p) = 3(p + 4) ... Move all terms containing p to the left, all other terms to the right. ... When you enter an equation into the calculator, the calculator will begin by ... Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).

The graph

Step-by-step explanation:

If you see, the graph goes up 40 for every 1 is goes over. The equation will go up 35 for every 1 it goes over. Thus, the graph has the greater slope.

5(2+x)=5

or, 10+5x=5

or, 5x= -5

or, x= -1

Answer:

12meters

Step-by-step explanation:

Step one:

given data

Length= 4 meters

Width= 3 meters

Let us find the diagonal by applying Pythagoras theorem

[tex]z^2= x^2+y^2\\\\z^2= 4^2+3^2\\\\z^2= 16+9\\\\z^2= 25\\\\[/tex]

z=√25

z= 5meters

Step two:

Hence the total distance Victor has covered is

total= 4+3+5

total= 12meters

Answer:

-7

Step-by-step explanation:

-247 is the value of expression  d³a²−(c+b) for a=−2 , b=3 , c=−12 , and d=−4 .

An expression is combination of variables, numbers and operators.

The given expression is d³a²−(c+b)

d cube times of a square minus c plus d

a,b, c and d are variables

plus and minus are operators.

Given values of a, b c and d are

a=−2 , b=3 , c=−12 , and d=−4 .

Substitute these values in expression

(-4)³(-2)²-(-12+3)

(-64)(4)-(-9)

(-64)(4)+9

Minus two hundred fifty six plus nine

-256+9

Two hundred forty seven

-247

Hence -247 is the value of expression  d³a²−(c+b) for a=−2 , b=3 , c=−12 , and d=−4 .

Answer: c = -3/2

Step-by-step explanation:

1. Subtract 8/3 from both sides —> you get 3/2c = -9/4

2. Divide both sides by 3/2 —> -9/4 x 2/3 = -3/2

Complete Question

Mark has 42 coins consisting of dimes and quarters. the total value of his coins is $6. How many of each type of coin does he have?

Answer:

The number of dimes = d = 30 dimes

The number of quarters = q = 12 quarters

Step-by-step explanation:

Let us represent

The number of dimes = d

The number of quarters = q

A dime is worth 10 cents = 0.10d

A quarter is worth 25 cents = 0.25q

Mark has 42 coins consisting of dimes and quarters.

q + d = 42...... Equation 1

q = 42 - d

The total value of his coins is $6.

0.1d + 0.25q = 6

We substitute 42 - d for q

0.1d + 0.25(42 - d) = 6

0.1d + 10.5 - 0.25d = 6

10.5 - 6 = 0.25d - 0.1d

4.5 = 0.15d

d = 4.5/0.15

d = 30 dimes

Solving for q

q = 42 - d

q = 42 - 30

q = 12 dimes

Therefore,

The number of dimes = d = 30 dimes

The number of quarters = q = 12 quarters

Answer:

x = -3: [tex]y = 10[/tex], x = -2: [tex]y = 4[/tex], x = -1: [tex]y = 0[/tex], x = 0: [tex]y = -2[/tex], x = 1: [tex]y = -2[/tex], x = 2: [tex]y = 0[/tex], x = 3: [tex]y = 4[/tex]

Step-by-step explanation:

Let [tex]y = x^{2}-x-2[/tex], where [tex]x[/tex] and [tex]y[/tex] are the independent and dependent variables, respectively. The approach consists in evaluating the function at values presented in statement:

x = -3

[tex]y = (-3)^{2}-(-3)-2[/tex]

[tex]y = 10[/tex]

x = -2

[tex]y = (-2)^{2}-(-2)-2[/tex]

[tex]y = 4[/tex]

x = -1

[tex]y = (-1)^{2}-(-1)-2[/tex]

[tex]y = 0[/tex]

x = 0

[tex]y = (0)^{2}-(0)-2[/tex]

[tex]y = -2[/tex]

x = 1

[tex]y = (1)^{2}-(1)-2[/tex]

[tex]y = -2[/tex]

x = 2

[tex]y = (2)^{2}-(2)-2[/tex]

[tex]y = 0[/tex]

x = 3

[tex]y = (3)^{2}-(3)-2[/tex]

[tex]y = 4[/tex]
