A, B & C lie on a straight line. D, C & E lie on a different straight line.Angle y = 115° and angle z = 62°.Work out x, explaining each stage of your working in the comment box.

Answers

Answer 1

Answer:

x = 127°

Step-by-step explanation:

Find the diagram attached

First we need to get <DBC

<DBC =180-y

<DBC = 180-115

<DBC = 65°

The sum of interior angles is equal to exterior

Hence <DBC+ z = x

65+62 = x

x = 127°

A, B & C Lie On A Straight Line. D, C & E Lie On A Different Straight Line.Angle Y = 115 And

Solve y =-2x
y = 3x + 5
by using substitution method

Answers

Answer:

y = -2x

y = 3x + 5

<=> 3x + 5 = -2x

y = -2x

<=> 5x = -5

y = -2x

<=> x = -1

y = -2x

<=> x = -1

y = (-2)(-1) = 2

so (x; y) = (-1; 2)

Answers

Answer:

a 90

b 90

a 8x+40

b 4y-36

c -6n-3

d 7x+7

e -10x+30

f 4/1x+2/1

Alright, this is a lot.

This start with the first question (3)

Find the product of 5(18) and 5(18) = 90

To get that is 5(18) = (5 x 18 = 90)

So now we have to do the math for both A and B and find out which one is 90

A 5(10+8) : 10 + 8 = 18 so (a) = 5(18)
B 5(20-2) : 20 - 2 = 18 also well

I think (a) would be your best bet. For question (3)

Alright question 4

(a) = 8x + 40
(b) = 4y - 36
(c) = -6n - 18
(d) = 7x + 7
(e) = 30-10x
(f) = 4x + 2

Hope this helps in any way. Tell me if It's right

Use the information given to write the equation for the quadratic function.
a. The x-intercepts are (-4, 0) and (3,0), and the parabola opens down.
b. The vertex is (-8, -2), and the parabola opens up.

Answers

Answer:

y = -x² - x/22 + 6/11

Step-by-step explanation:

Standard form, is y = ax² + bx + c

We need to use standard form (though we could use vertex form, but it is easier to do standard form)

Substitute the x and y values that they give into y = ax² + bx + c

Because the parabola passes through...

(-4, 0), then 0 = (-4)²a + (-4)b + c

(3, 0), then 0 = 9a + 3b + c

(-8, -2), then -2 = 64a - 8b + c

So, we get this system:

16a − 4b + c = 0

9a + 3b + c = 0

64a − 8b + c = −2

Because you are learning about parabolas, I am assuming that you can solve a system, but the answers are:

a = -x²/22

b = -x/22

c = 6/11

So, the equation of the parabola is:

y = -x²/22 - x/22 + 6/11

Question: What are the solutions to this graph?

Answers

Answer:

The solution to the graph are x = -2 and x = 2

Step-by-step explanation:

Here, we want to get the solution to the graph

As we can see, the graph is parabolic; which is a property of a quadratic polynomial

The solution refers to the value at which the graph plot crosses the x-axis

In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis

We can see this happen at two points

These are the points x = -2 and x = 2

Two cyclists start from the same point at the same time and move in opposite directions. One cyclist is traveling at 12 mph, and the other cyclist is traveling at 8 mph. After 30 min, how far apart are the two cyclists?
mi

Answers

An hour is 60 mins long. 30 mins is half of it. If we take 12 miles in an hour, divide it by 2, it will be 6 miles in 30 mins, and if we take 8 miles, divide it by 2, it would be 4 miles in 30 mins. Since the questions telling us how far apart are north cyclists, we’re adding 6 and 4 to get 10 miles. In conclusion, both cyclists are 10 miles apart. I might be wrong, but that’s the best I can do.
