Answer:

1

Step-by-step explanation:

6 - 5(2x-3) = 4x + 7

-5(2x-3) = 4x + 1

-10x + 15 = 4x + 1

-14x = -14

14x = 14

x = 1

Answer:

Quantative data

Answer:

25

Step-by-step explanation:

The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

Answer:

Step-by-step explanation:

9) a = 2 ; b = 6

a) a + b =  2 + 6 = 8

b) b - a = 6 - 2 = 4

c) ab = 2 * 6 = 12

10) c = 12 ; d = 4

a) c ÷ d = 12 ÷ 4 = 3

b) c + d = 12 + 4 = 16

c) c - d = 12 - 4   = 8

Distance = Speed × Time

Distance = 68 × 53

Distance = 3,604 km

Answer:

Tessa's expression is false because -7 times -4 is positive 28, not -28.

Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)

Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.

2-21x+28

The equivalent expression for the given expression is 2-21x+28.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Tessa:

2-7(3x-4)=2-21x-28

Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.

Bernette:

2-7(3x-4)=-5(3x-4)

Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4

Lucy:

2-7(3x-4)=2-21x+28

Lucy's equivalent expression is correct.

Therefore, the equivalent expression is 2-21x+28.

Step-by-step explanation: please do mark as brainliest

Answer: (-2, 4)

Concept:

There are three general ways to solve systems of equations:

Here we are going to use substitution since the variable [y] is being isolated in both equations.

Solve:

Given equations

y = -x + 2

y = -3x - 2

Using the method of substitution to combine the equations

-x + 2 = -3x - 2

Add 3x on both sides

-x + 2 + 3x = -3x - 2 + 3x

2x + 2 = -2

Subtract 2 on both sides

2x + 2 - 2 = -2 - 2

2x = -4

Divide 2 on both sides

2x / 2 = -4 / 2

[tex]\boxed{x=-2}[/tex]

Find the y value

y = -x + 2 →→→ Given expression

y = -(-2) + 2 →→→ Substitute values into the expression

y = 2 + 2 →→→ Simplify the value

[tex]\boxed{y=4}[/tex] →→→ SImplify by addition

Answer:

  b = 20/7

Step-by-step explanation:

The slope of the first line can be found by solving for y:

  by = -5x +6 . . . . . . add 6-5x

  y = -5/b +6/b . . . . . divide by b

The slope is -5/b.

The slope of the second line can be found by solving for y:

  7y = 4x +7

  y = 4/7x +1 . . . . . . divide by 7

The slope is 4/7.

For the lines to be perpendicular, the product of these slopes must be -1:

  (-5/b)(4/7) = -1

  -20/(7b) = -1 . . . . simplify

  b = 20/7 . . . . . . . multiply by -b

The lines will be perpendicular when b = 20/7.

Hello!

Are you in algebra?

Here is how to solve and graph.

First, look for the slope and y-intercept of your equation.

y = - 1/2r-6

The y intercept is, -6

The slope is -1/2

the variable r, is another way to represent x, as it is just a variable.

now that you have all that information, plot -6 on the graph, -6 should be on the y- axis.

from that point, move down one space and move right two space. complete this step multiple times.

Now please look at the photo, and Here's what the graph should look like.

Answer:

A. the slope value is 1/4

B. 0

C. y = 1/4x

Step-by-step explanation:

A: the slope can be calculated with the formula

[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]

m is the slope

(x1, y1) is your first coordinate point (any point will work)

(x2, y2) is your second coordinate point (any point will work)

Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - 0}{4 - 0} = \frac{1}{4} [/tex]

B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.

C:

the equation of the graph is y = mx + b.

m is the slope = 1/4

b is the y-intercept = 0

Therefore the equation is y = 1/4x
