PLZ HELP RIGHT NOW PLZ I WILL MARK BRAINLIEST I BEG NO SILLY ANWSER =(
kipiarov [429]

Answer:

1. x=-3

2. m=4

3. -6=b

4. x=3

Step-by-step explanation:

1. 7(3-3x)=84 what is x

- Distribute the 7 using distributive property, which will give you 21-21x=84.

- Add 21 to both sides to aim to isolate the x variable, which will give you -23x=63.

- Divide both sides by the coefficient of x, -23, to finally get x by itself: x=-3

2. -7(-4-3m)=112 what is m

- Distribute the -7 using distributive property, which will give you 28+21m=112. Be wary of negatives.

- Subtract 28 to both sides, which will give you 21m=84.

- Divide both sides by 21 (the coefficient of m) to get m by itself: m=4

3.-182=7(2b-8)+7b what is b

- Distribute the 7 using distributive property, which will give you -182=14b-56+7b

- Add like terms to get -182=21b-56.

- Add both sides by 56, which will get you -126=21b.

- Divide both sides by the coefficient of b, 21, to get b by itself: -6=b

4. -101 = -5(8x-5) -6 what is x

- Distribute the -5 using distributive property, which will give you -101=-40x+25-6. Beware of negatives.

- Add like terms to get -101=-40x+19.

- Subtract both sides by 19 to get -120=-40x.

- Divide both sides by 40 (the coefficient of x) to get 3=x.

Hope this helps!

1. y and x have a proportional relationship, and y = 7 when x = 2. What is the value of x when y = 21?
Alex

Answer:

Proportional relationship states that one in which two quantities vary directly with each other.

In other words, we say the variable y varies directly as x if:

  y = kx , where k is constant of proportionality.

(1)

Given: y and x varies a proportional relationship, and y = 7 and x=2

find the value of x when y =21

By the definition of proportional relationship;

y = kx                  ......[1]

Substitute the value y= 7 and x = 2 to solve for k;

7 = 2k

Divide by 2 to both sides we get;

\frac{7}{2} =\frac{2k}{2}

Simplify:

k = 3.5

Now,  substitute the value of k = 3.5 and y =21 in equation [1] to find the value of x.

21 = 3.5 x

Divide both sides by 3.5 we get;

\frac{21}{3.5} =\frac{3.5x}{3.5}

Simplify:

x = 6

Therefore, the value of x is 6.

(2)

Given: y and x varies a proportional relationship, and y = 9 and x=2

find the value of y when x=3.

By the definition of proportional relationship;

y = kx                  ......[1]

Substitute the value y= 9 and x = 2 to solve for k;

9 = k\cdot 2

Divide by 2 to both sides we get;

\frac{9}{2} =\frac{2k}{2}

Simplify:

k = 4.5

Now,  substitute the value of k = 4.5 and x=3 in equation [1] to find the value of y.

y= 4.5 \cdot 3

Simplify:

x = 13.5

Therefore, the value of y is 13.5.

(3)

From the given table,

y = 2.8 when x = 2

by the definition of proportional relationship;

2.8 = k \cdot 2

or

2.8 =2k

Divide by 2 to both sides, we get;

\frac{2.8}{2} =\frac{2k}{2}

Simplify:

k = 1.4

Therefore, the equation that represents the table is; y = 1.4 x

The rule as a mapping for the translation of a rectangle is (x, y) = (x - 2, y + 7). Which describes this translation?
Brums [2.3K]

Answer:

a translation of 2 units to the left and 7 units up

Step-by-step explanation:

Translation of points (x,y)

At point x, the function can be translated to the left or to the right.

(x-a) is the translation of the point a units to the left, and (x+a) is the translation of the point a units to the right.

At point x, the function can be translated up or down. y+a represents a shift of a units up, and y-a represents a shift of a units down.

(x, y) = (x - 2, y + 7)

x - 2: 2 units to the left.

y + 7: 7 units up

So the fouth option is correct.
