C. X=33
D. X=52

Answer:

a T-shirt costs £5

a hat costs £2

Step-by-step explanation:

Suppose

A T-shirt=x

A Hat=y

So the equation is

8x+y=42

3x+y=17

So

8x+y=42

3x+y=17

------------

5x=25

x=5

So a T-shirt costs £5

3.5+y=17

15+y=17

y=2

So a hat costs £2

Answer:

t-shirt: £5

hat: £2

Step-by-step explanation:

(Ax² + Bx + C)²

= (Ax² + Bx + C)(Ax² + Bx + C)

= Ax⁴ + 2ABx³ + 2ACx² + 2BCx + C².

By Comparing Coefficients, we have:

A = 1

2AB = 6

2AC = 7

2BC = a

C² = b

Solving them we get A = 1, B = 3 and C = 3.5.

Therefore a = 2BC = 2(3)(3.5) = 21,

b = C² = (3.5)² = 12.25.

Answer:

x=30

y=4

Step-by-step explanation:

Since there is an equilateral triangle, those angles =60°, and all sides to that triangle are equal.

You can determine y by looking at the congruent lines on the second triangle. In this triangle, we see that two sides, one of which is a side to the equilateral triangle, are equal to 20. Because one of these sides is a side to the equilateral, we know that all sides of the equilateral triangle are equal to 20, so using simple algebra you can determine that y=4.

To solve for x is a little more difficult. In the equilateral triangle, we know that all angles =60°, therefore we can solve for two angles to use to solve for x. We can solve for the obtuse angle by subtracting 60 from 180=120. then we can solve for the next angle that is next to the equilateral triangle because these two make a right angle so 90-60=30. Now you add the angles you just solved for, subtract that sum from 180, and you get x.

120+30=150

180-150=30

x=30

The coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

What is midpoint of line segment?

The midpoint divides the line segment into two equal parts. As the number line progresses, the leftmost numbers become smaller, and the rightmost numbers become larger. Adding, subtracting, and multiplying can also be done using a number line like for addition move towards right and for subtraction move towards left.

Here, the mid point of line EF is M with coordinates (1,-1) with coordinates  of E(-3,2) therefore, using mid point formula to find coordinates of F(x,y)

[tex]\begin{aligned}\frac{-3+x}{2}&=1\\x&=2+3\\&=5\end{aligned}[/tex]

and for y coordinates of F :

[tex]\begin{aligned}\frac{2+y}{2}&=-1\\y&=-2-2\\&=-4\end{aligned}[/tex]

Therefore, the coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

Answer:

Step-by-step explanation:

Coefficients are the numbers that come BEFORE a variable, just as 55 is in the term 55x. Constants are numbers in an equation that never change, unless you add them with another constant. For example, in the equation 34x+55=24, the constants are 55 and 24. The only way that either changes is by subtracting the 55 from the 24.

The correct answer is graph B.

Hope This Helps! Sorry for late answer!

Answer:

its A because because the slope of the y-intercept is on the possative base towards the iquantities which is to be a posative number, in that case the y-intercept adds a 1 to the x which would lead towards the negative side therefor your answer will be y < -x -2

Answer:

Area = a²

Step-by-step explanation:

For a square, all 4 sides are equal. If a be the side of a square and A be its area. Then, the area of a square is given by :

Area = side²

or

Area = a²

Hence, the area of a square is square of the length of its side.

Answer:

7:47

Step-by-step explanation:

Here are two ways of solving this:

The video will be half the time of 15:34, so you need to divide the time 15:34 by 2.

Method 1)

Use the tip. The video is 15 minutes and 34 seconds long.

Convert minutes to seconds: 15 * 60 = 900

Add 34 seconds to the 15 minutes: 900 seconds + 34 seconds = 934 seconds

The video is 934 seconds long.

Divide the total seconds by 2: 934/2 = 467

467 seconds = 420 seconds + 47 seconds = 7 minutes and 47 seconds

Answer: 7:47

Method 2)

Divide the minutes by 2 and divide the seconds by 2.

15 minutes and 34 seconds.

Divide minutes by 2: 15/2 = 7.5

Divide seconds by 2: 34/2 = 17

Now we need to add 7.5 minutes and 34 seconds.

0.5 minutes is half a minute, so it's 30 seconds.

7.5 minutes + 17 seconds =

= 7 minutes + 0.5 minute + 17 seconds

= 7 minutes + 30 seconds + 17 seconds

= 7 minutes + 47 seconds

= 7:47

Step-by-step explanation:

Answer: Well there's a geometry definition stating that the two angles are equal.

But ig i can try to make a proof.

First make a perpendicular bisector from the vertex to the bottom splitting the bottom side in half.

Now because of LL theorem, and the reflexive property, the two triangles are equal.

Now using cpctc, the two angles are also equal.

Step-by-step explanation:

Using the Pythagorean Theorem, it is found that the size of the monitor is of 38 centimetres.

------------------------

In a right triangle with legs [tex]l_1[/tex] and [tex]l_2[/tex] and hypotenuse h, these measures are related by the Pythagorean Theorem, given by:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem:

[tex]s^2 = l^2 + w^2[/tex]

[tex]s^2 = 24^2 + 30^2[/tex]

[tex]s = \sqrt{24^2 + 30^2}[/tex]

[tex]s = 38[/tex]

The size of the monitor is of 38 centimetres.

Step-by-step explanation:

Johns boat was 30 miles away. It traveled 20 miles in 5 hours (50-30 = 20)

20/5 = 4

It traveled at 4 miles per hour.

The equation for Roberta’s boat multiplied 5 by x( number of hours) so this means her boat is traveling at 5 miles per hour.

Then 25 gets added at the end, this means her boat was 25 miles away at the beginning.

Johns boat was further away at the beginning and Robertas boat is traveling faster.
