I NEEED HELP WITH THIS MATH

Answers

Answer:

3. they combined like factors incorrectly X=21.5

4. Supplementary means it's equal to 180, not 90. they did it as if the angle was acute. The answer should be 133 degree

5. The two angles are not equal. however, the two angles added together equal to 180. 115+ 5x -10 = 180 X=15

Step-by-step explanation:

3. 8x + 8 = 180

8x + 8 - 8 = 180 - 8

8x = 172

8x/8=172/8

x=21.5

4. 180-47= 133

5. 115 - 10 + 5x = 180

105 + 5x = 180

105-105+5x=180-105

5x=75

5x/5=75/5

x=15

A billboard on level ground is supported by a brace as shown in the accompanying diagram the measure of angle is 15° greater than twice the measure of angle b determine the measure of angle a in the measure of angle b

Answers

Answer:

has a right angle to hold the billboard upright. Since a triangle is 180, and there' s a right angle, then when you add angle A and angle B together, they should add up to 90.

Step-by-step explanation:

A = 2B + 15

A + B = 2B+15 + B = 90

3B + 15 = 90

3B = 75, so B = 25 degrees

90 - B = A, so A = 65 degrees

In a scale model of the Eiffel Tower, 10 centimeters represent 65 meters. If the real Eiffel Tower is approximately 325 meters tall, how tall is the plastic model?

Answers

Answer:

The plastic model is 50 meters tall

Step-by-step explanation:

Here, we want to know how tall is the plastic model

In the plastic model 10 m represents 65 meters

then x meters plastic = 325 m real

10 * 325 = 65 * x

3250 = 65x

x = 3250/65

x = 50 meters

Identify the y-intercept of the function 7x + 2y = 4.

Answers

Explanation: Standard form of equation of line is y=mx+c , where c is the y-intercept. So the y-intercept is −6 The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the y-intercept is 0 .So according to our formula of y=mx+b, where m is slope, our slope is −72 which would also be −3.5Explanation: The slope-intercept form is y=mx+b where m is the slope value. In the equation y=2x , the m value is 2 . Therefore, 2 is the slope.It is written as Ax+By=C. You can also change slope-intercept form to standard form like this: Y=-3/2x+3. Next, you isolate the y-intercept(in this case it is 3) like this: Add 3/2x to each side of the equation to get this: 3/2x+y=3. You can not have a fraction in standard form so you solve this. the X- and Y-Intercepts of a Line in Slope-Intercept Form? To find the x-intercept of a given linear equation, plug in 0 for 'y' and solve for 'x'. To find the y-intercept, plug 0 in for 'x' and solve for 'y'.To find the y-intercept let x = 0 and solve for y. Step 3: Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).

Someone please help me

Answers

To hit the bulls eye the table would read
x=3.5 y=2

Can someone help please?

Answers

Answer:

1) 2<x<10 (the first choice)

2) 17<x<40 (the first choice)

3) x<-1 or x>2 (the second choice)

Step-by-step explanation:

1) 2<x<10...this is another way of representing x<10 and x>2 in an "and" inequality. If you look at 2<x<10 from left to right, it says 2 is less than x and x is less than 10.

2) 17<x<40...this represents x>17 and x<40 in an "and" inequality as well. If you look at 17<x<40, it reads 17 is less than or equal to x and x is less than 40.

3) x<-1 or x>2...the signs are greater than or equal to because the dots are closed on the number line. Also, this is not an "and" inequality. This is actually an "or" inequality. You can mainly tell because the lines are shaded opposite ways and do not intersect.

to y=-3x + 2. Which person is
correct and why?
A Casey is correct. In order to find
the perpendicular line to another
line, one must take the
reciprocal of the slope.
B Tara is correct. In order to find
the perpendicular line to another
line, one must find the negative
reciprocal of the slope.
C Neither person is correct.
D Both Tara and Casey are
correct.

Casey is wrong, however, I am unsure whether y=fx-1 is part of the problem or a mistake. A perpendicular slope to -3 must be 1/3.
