Answer:

x=4, y=-2

Step-by-step explanation:

-5x+8y=-36

5x+7y=6

eqn 1+ eqn 2 gives

15y=-30

divide both sides by 15

y=-2, put in eqn 2

5x+7(-2)=6

5x=20 divide both sides by 5

x=4

Answer:

2.4 cm

Step-by-step explanation:

We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.

Let's find the midpoint of AB.

Next let's find the midpoint of BC.

In order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.

Therefore, the difference between the midpoints of AB and BC is 2.4 cm.

Answer:

0.32

.22

regular (capuccino is incorrect)

Step-by-step explanation:

in the mocha column 25 people prefer hot and 12 people prefer cold are equal to 37 people.  25+12=37

relative frequency of preferring cold is 12.  12÷37 = .32

In the hot column 11, 25, 19, 30 people are combined for total of 85 people who prefer hot coffee.  11+25+19+30=85

relative frequency of preferring a latte is 19: 19÷85 = .22

combine regular column for 17 ÷ 28 = .61

combine mocha column for 12÷40 = .30

combine latte column for 20÷39 = .51

combine cappucino column for 27÷57 = .47

The type of coffee that has the highest percentage of people who prefer it cold is regular.  (if you combine only the cold column you will end up with cappuccino which is wrong.)

Answer:

2= 95 degrees

3= 25 degrees

1= 60 degrees

5= 25 degrees

4= 95 degrees

Step-by-step explanation:

2) Straight line is 180 degrees so

180-85=95 degrees

3) I got 25 degrees because it's a corresponding angle of X, which is parallel to 25.

1) A triangle is always 180 degrees, 95+25=120 180-120=60

5) Its another corresponding angle to 25

4) Straight line is 180 degrees 60+25=85 180-85=95

Or you could of worked out the bottom 85 and minus it from 180 which will also correspond to 4

Answer:

y = 36

Step-by-step explanation:

[tex]\frac{y}{3}+2 = 14\\\\\frac{y}{3}=14-2\\\\\frac{y}{3}=12\\\\y = 12*3\\\\y = 36[/tex]

Answer:

x = 4, y = 9.

Step-by-step explanation:

3x -2y = -6 and y = x+5

Substitute y = x + 5 in the first equation:

3x - 2(x + 5) = -6

3x - 2x - 10 = -6

x = -6 + 10

x = 4

So y = 4 + 5 = 9.

Answer:

1.26 but rounded to the nearest 10 would be 1.3 so 1.3 is your answer

Step-by-step explanation:

Answer:

$159.75

Step-by-step explanation:

137.45/252.60 + x = 1/3

252.60 + x = 412.35

x = 412.35 - 252.60

x = 159.75

Answer:

297.2

Step-by-step explanation:

549.8 ÷ 4 = 137.45

549.8 - 252.60 = 297.2

Answer: 110 degrees

Since the 2 unknown angles in the triangle are equal you do (180-40)/2 to find what they are equal to. (It's equal to 70) Now that you have the answer for the two angles, now you can subtract 70 from 180 which gives you 110 degrees and that's your answer

Hope this helped you!

Answer:

x°+x°+40°=180°

2x°=180°-40°

2x°=140°

x°=140°

2

x°=70°

x°=70°

therefore,

x=180°-70°

x°=110°

a^2 + b^2 =c^2

1^2 + 2^2 = 1+4 = 5

so no it doesn't make a right triangle

Answer:

x = 82°

Step-by-step explanation:

The triangle sum theorem states that the sum (total measure) of all angles in a triangle must add up to 180°.

Therefore:

60° + 38° + x° = 180°

98° + x° = 180°

98° – 98° + x° = 180° – 98°

x = 82°

Answer:

D(-4,-6)

Step-by-step explanation:

if you were to rotate it once 90 degrees it would land on (6,-4) and then rotating it once more it would land on (-4,-6).

Answer: the 10th term is 4.1

Step-by-step explanation:

The sum is +0.4 each time.

1=0.5

2=0.9

3=1.3

4=1.7

5=2.1

6=2.5

7=2.9

8=3.3

9=3.7

10=4.1

Answer:

The answer is 23

Step-by-step explanation:

0.5, 0.9, 1.3, 1.7, 2.1, 2.5, 2.9, 3.3, 3.7, 4.1

You get the remaining terms by adding 0.4 to the previous number.  Once all of the terms are found, add them up and you get an answer of 23.

Answer:

Answer choice one

Step-by-step explanation:

To find the perpendicular line to a given line, just give the reciprocal of the slope and flip the sign.

In this case, you first put the line into the slope-intercept form which would be y=2x-7.

the slope is 2x and the reciprocal is 1/2 and then you flip the sign to be -1/2.

The only one with that slope is answer choice 1.

Step-by-step explanation:

Un coeficiente es un número o símbolo multiplicado por una variable o una cantidad desconocida en un término algebraico, polinomio, una serie o cualquier expresión.

a) 5x² + 4x + 2 = 0

El coeficiente de x² = 5, el coeficiente de x = 4

b) –x² + 3x + 4 = 0

El coeficiente de x² = -1, el coeficiente de x = 3

c) x² - 4x + √7 = 0

El coeficiente de x² = 1, el coeficiente de x = -4

d) x² + 8 = 0

El coeficiente de x² = 1, el coeficiente de x = 0

Answer:

(3, 1.7)

Step-by-step explanation:

The point at which the vertices of a triangle meet is known as the orthocenter of the triangle. The orthocenter passes through the vertex of the triangle and is perpendicular to the opposite sides.

Two lines are perpendicular if the product of their slopes is -1.

The slope of the line joining D(0,0), F(3,7) is:

[tex]m_1=\frac{7-0}{3-0}=\frac{7}{3}[/tex]

The slope of the line perpendicular to the line joining D and F is -3/7. The orthocenter is perpendicular to the line joining D and F and passes through vertex E(7, 0). The equation is hence:

[tex]y-y_1=m(x-x_1)\\\\y-0=-\frac{3}{7} (x-7)\\\\y=-\frac{3}{7}x+3 \ .\ .\ .\ (1)[/tex]

The slope of the line joining E(7,0), and F(3,7). is:

[tex]m_1=\frac{7-0}{3-7}=-\frac{7}{4}[/tex]

The slope of the line perpendicular to the line joining E and F is 4/7. The orthocenter is perpendicular to the line joining E and F and passes through vertex D(0, 0). The equation is hence:

[tex]y-y_1=m(x-x_1)\\\\y-0=\frac{4}{7} (x-0)\\\\y=\frac{4}{7} x\ .\ .\ .\ (2)[/tex]

The point of intersection of equation 1 and equation 2 is the orthocenter. Solving equation 1 and 2 simultaneously gives:

x = 3, y = 1.7
