simplify the expression 7(a+4b)-3c​

Answer:

The value of y is 1

Step-by-step explanation:

4 - (y - 3) = 3(y + 1) - 4(1 - y)

4 - y + 3 = 3y + 3 - 4 + 4y

7 - y = 7y - 1

7 + 1 = 7y + y

8y = 8

y = 1

Thus, The value of y is 1

Answer:

y = -5/2x + -4 (or) y = -5/2x - 4

Step-by-step explanation:

Your slope is -5/2, so all you have to do is take the point (-2, 1) and use the slope to find a second point of (0, -4) which is coincidentally the y-intercept. Then you just plug the data into the equation y = mx+b. You do that and you get the answer of y = -5/2x+-4

Answer: 13

Step-by-step explanation:

Step-by-step explanation:

the slope is the y/x ratio of the y and x coordinate differences when going from one point to the other. and it is always the factor of x in the equation.

x changes by 4 units (from 0 to 4), y changes by -1 unit (from 3 to 2).

so, the slope is -1/4.

the intercept means the intercept with the y-axis. and that means the y value when x = 0. which is given already by the first point : 3

so, the equation is

y = -1/4 x + 3

B is the answer hope you get it right

Answer:

given m<4 = 35° and m<1 = m<2 + m<4

prove m<3 = 70°

Statements Reasons

m<4 = 35° given

m<1 = m<2 + m<4 given

m<2 = m<4 by the vertical angles theorem

35° = 35° substitution property of equality

m<2 + m<4 = m<1 angle addition postulate

35° + 35° = 70° substitution property of equality

m<3 = m<1 by the vertical angles theorem

m<3 = 70° substitution property of equality

The two column proof for the given set of angles are:

m∠2 = m∠4 by the vertical angles theorem

m∠3 = m∠1 by the vertical angles theorem

Given data:

The measure of angle

The measure of angle m∠4 =35,

The measure of angle m∠1= m∠2 + m∠4.

Now, Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.

Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

Therefore, m∠2 = m∠4 by the vertical angles theorem

m∠3 = m∠1 by the vertical angles theorem

35° + 35° = 70° substitution property of equality

Hence, the measure of angle m∠3 = 70°

given that,

we have to find  the measure in degrees (pi)/4.

now, we know that,

Measure of an Angle in Degrees = 180°        

Measure of an Angle in Radians is:

180° × (π/180°) = π = 3.14 Rad

so, we have,

π/4

= π/4 × (180°/π)

=180 /4

=45°

Hence, the measure in degrees (pi)/4 is 45°.

Answer:

To find the Y-intercept substitute in 0 for all the x's and solve for Y

Your answer would be (0,9/2)

Steps:

Y=0^2-5(0)+9/2

0^2 -5(0)=0

Y=9/2

0 is your x place

and 9/2 is your Y intercept

Answer:

y-intercept = 9/2 or 4.5

Step-by-step explanation:

In the given quadratic equation, y = x² - 5x + 9/2, where:

a = 1, b = -5, and c = 9/2  

The y-intercept is the point at which the parabola crosses the y-axis, and occurs at point (0, c ).  It is the value of y when x = 0. To find out what I mean by this, we can substitute the value of x = 0 into the quadratic equation:

y = x² - 5x + 9/2

y = (0)² - 5(0) + 9/2

y = 0 - 0 + 9/2

y = 9/2

Therefore, the y-intercept (c) = 9/2, and has coordinates, (0, 9/2) or (0, 4.5).

Attached is a screenshot of the graph, where it shows the y-intercept.

(1) False

A dilatation enlarges or reduces the original figure

Then the distance between consecutive vertices changes.

(2)

Assuming the centre of dilatation is at the origin then multiply the coordinates of the points by the scale factor k = 0.25 ( a reduction )

J (4, 8 ) → J' (4(0.25), 8(0.25) ) → J' (1, 2 )

K (8, 8 ) → K' (8(0.25), 8(0.25) ) → K' (2, 2 )

L (4, 2 ) → L' (4(0.25), 2(0.25) ) → L' (1, 0.5 )

Answer:

Step-by-step explanation:

We don't know the definitions, properties, postulates, or theorems on your list, so we'll use the following:

__

∠a = 180° -47° = 133°; reasons 2, 5. The angles form a straight angle.

∠b = 47° -32° = 15°; reason 4

∠c = 90° - ∠b = 90° -15° = 75°; reason 3

∠d = 90° -32° = 58°; reasons 1, 5. The angles form a right angle. If you want to get picky, we know it is a right angle by reasons 1 and 2. The marked right angle and the sum of 32° and ∠d together form a straight angle.

-2 -2 = -2•2

-4 = -4

Yes, the ordered pair is the solution

9. b)

-1 = 3•(-2) +5

-1 = -6 +5

-1 = -1

3•(-2) +(-1) = -2

-6 -1 = -2

-7 ≠ -2

No, the ordered pair is not the solution

10. (-1, -1) and (3, -1)

y = 6 +x

Now substitute it in the first equation:

3•(6 +x) = 5x

18 + 3x = 5x

18 = 2x

x = 18/2

x = 9

Now, substitute x = 9 in the second equation:
