Answer 1
I most positively sure is A( the 1st one)
Answer 2

Answer:

The correct answer is: The y-intercept is 4

Step-by-step explanation:

A. (correct) explanation-The y-intercept is the point where the line crosses the y-axis (vertical line). The y-intercept here is 4 because that is the point where the line crosses the y-axis

B: The x-intercept is 0 (wrong)

B is wrong because the x-intercept is the point where the line crosses the

x-axis (horizontal line)

C: (wrong) A savings account started with $8 in it

C is wrong because the initial amount is usually the y-intercept, but here the y-intercept is 4.

D: (wrong) It took 4 mins to run a mile

D is wrong because there should have been a point at the location (1,4) for this statement to be true, but there is no point there

Solve the y for the equation 5x-2y=10

Answers

Answer:

y = 5/2x - 5

Step-by-step explanation:

Step 1: Write equation

5x - 2y = 10

Step 2: Solve for x

Subtract 5x on both sides: -2y = 10 - 5xDivide both sides by -2: y = -5 + 5/2xRewrite: y = 5/2x - 5

Answer:

y = (5/2)x - 5

Step-by-step explanation:

5x-2y = 10

Subtract 5x from both sides

-2y = 10 - 5x

Rearrange

-2y = -5x + 10

divide both sides by -2 to isolate y

y = (5x/2) + (10/-2)

y = (5/2)x - 5

b is a point between a and c where ac = 5x, ab = 12, and bc = 3x + 2. what is the measure of the length of ac?

Answers

Answer:

AC=22

Step-by-step explanation:

The measure of the Length of AC is; 35

We are given;

ac = 5x

ab = 12

bc = 3x + 2

We are told that b is between a and c. This means that;

ab + bc = ac

Thus;

12 + 3x + 2 = 5x

14 + 3x = 5x

Subtract 3x from both sides to get;

5x - 3x = 14

2x = 14

x = 14/2

x = 7

Thus, ac = 5x = 5 * 7

ac = 35

how can you find a ratio in a bar graph​

Answers

Divine the total number of the entire chart by the number of a single line or bar to give you the ratio in a bar or line chart. For example, if a bar or line represented 5 in a chart with a total of 30, you would divide 30 by 5. This would give you a result of 6. Therefore, the ratio would be 6:1.

B. x + 2y = 11


C. 2x – y = – 3

Step-by-step explanation:

The equation for the perpendicular bisector of line segment XY is 2x + y = 7, the correct option is A.

What is the standard equation of a line?

The standard equation of a line is given by

y = mx+c

Here m is the slope and c is the y intercept

The slope can be determined by

m = (y₂ -y₁)/(x₂ -x₁)

The line segment XY  has the points  X(5, 7) and Y(–3, 3).

The slope of the line is,

m = ( 3 - 7) /( -3 - 5)

m = -4 / -8

m = 1 /2

The product of the slope of a line and a line perpendicular to it is -1.

( 1/2) * m' = -1

m' = -2

As it is a bisector , the midpoint of X and Y will be the point on the line.

Midpoint of XY is ( ( 5 -3)/2 , (7+3)/2 )

Midpoint of XY is ( 1 , 5)

The equation of the perpendicular bisector of line segment XY is,

y = -2x +c

5 = -2 + c

c = 7

So, the equation is,

y = -2x +7

2x +y = 7

Answer:

Step-by-step explanation:

x+ 7.05 = 45.3

Subtract 7.05 from each side

x+ 7.05-7.05 = 45.3-7.05

x =38.25

Let x be the number

x+3.5 = -4.3

Subtract 3.5 from each side

x+3.5 - 3.5 = -4.3-3.5

x = -7.8

Answer:

1. x=38.25

3. the second option

Step-by-step explanation:

1. x+7.05=45.3

(move the constant to the right)

2.

Answer:   x = 57

==================================================

Explanation:

The three angles of any triangle always add to 180

x+67+56 = 180

x+123 = 180

x+123-123 = 180-123 .... subtract 123 from both sides

x = 57

The missing angle is 57 degrees
