find slop for 7x-2y=0.2

Answer:

A

Step-by-step explanation:

using the sine ratio in the right triangle, then

sin 45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{5}[/tex]

multiply both sides by 5

note the exact value of sin 45° = [tex]\frac{\sqrt{2} }{2}[/tex]

x = 5 × sin 45° = 5 × [tex]\frac{\sqrt{2} }{2}[/tex] = [tex]\frac{5\sqrt{2} }{2}[/tex]

Probably the third answer is right. If you divide the 9x-6y=12 by 3, it gives you the exact same equation as the 3x-2y=4. They're the same, so they'd overlap.

Answer:

Step-by-step explanation:

Omar bought 15 pizzas in May.

In May, he bought 3 more than twice the number that he bought in April.

Since we don't know how many he bought in April, let X = the number of April pizzas.

Then, 15 = 2X + 3

Now you can subtract 3 from both sides, then divide both sides by 2 to leave X by itself and discover what it equals.

Final answer:

Omar bought 24 pizzas in April, calculated by setting up an equation based on the information that in May he bought three more than twice the pizzas he got in April.

Explanation:

The question is asking to find the number of pizzas Omar bought in April given that he bought three more than twice the number in May, and he bought 15 pizzas in May. To solve this, we can set up an equation: April Pizzas + 3 = 2 × (April Pizzas) + 2 × 3. Since we know that Omar bought 15 pizzas in May, we substitute 15 for the total number of Pizzas in May, which gives us: April Pizzas + 3 = 30. Subtracting 3 from both sides gives us April Pizzas = 27 - 3, so April Pizzas = 24. Therefore, Omar bought 24 pizzas in April.

Answer: There are 20 white lights.

Step-by-step explanation:

Given : There is a string of green and white lights strung around a mirror for every 6 green lights there are 4 white lights.

i.e. Ratio of green lights to white lights = 6:4

i.e.

[tex]\dfrac{\text{Number of green lights}}{\text{Number of white lights}}=\dfrac{6}{4}\\\\\Rightarrow\ \dfrac{30}{\text{Number of white lights}}=\dfrac{6}{4}\\\\\Rightarrow\ \text{Number of white lights}=\dfrac{4\times30}{6}=20[/tex]

Hence, there are 20 white lights.

THE GRAM

Step-by-step explanation:

Answer:

The correct option is C.

Step-by-step explanation:

The vertices of ABCD are A(2,-3), B(8,-6), C(14,-3), and D(8,0).

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The length of sides are

[tex]AB=\sqrt{(8-2)^2+(-6+3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]

[tex]BC=\sqrt{(14-8)^2+(-3+6)^2}=\sqrt{36+9}=\sqrt{45}[/tex]

[tex]CD=\sqrt{(8-14)^2+(0-3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]

[tex]AD=\sqrt{(8-2)^2+(0+3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]

Since length of all sides are equation therefore the given parallelogram cannot be a rectangle.

Slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of AB is

[tex]m_1=\frac{-6-(-3)}{8-2}=\frac{-3}{6}=\frac{-1}{2}[/tex]

Slope of BC is

[tex]m_2=\frac{-3-(-6)}{14-8}=\frac{3}{6}=\frac{1}{2}[/tex]

Since the slopes of two consecutive sides are not opposite reciprocals, therefore the given parallelogram is a rhombus. Option C is correct.

Step-by-step explanation:

Percentage by which the gas tank of the car is full = 40%

Amount of gas in the gas tank = 8 gallons

capacity of the gas tank = x gallons

40% * x = 8

(40/100) * x = 8

4x/10 = 8

4x = 8 * 10

4x = 80

x = 80/4

Answer   = 20 gallons

So since 1 multiplied by a number or variable, the number always stays the same we can say that 1(x-5)=x-5. We then, can open the parenthesis for 13*-3x+13*12. The answer for that would be -39x+156. So we then know that x-5-39x+156. We can simplify this until -38x+151.

A basketball priced at $35.00 with a 40% discount would cost $21.00 after the discount.

The final price of the basketball can be calculated by first identifying the amount being discounted from the original price. A 40% discount of a $35.00 basketball means you take 40% of 35. Here's how:

0.40 (40% converted to decimal) times $35.00 equals $14.00.

This $14.00 is the discount from the original price. Now, subtract this discount from the original price of the basketball to get the final price: $35.00 - $14.00 equals $21.00.

So, the final cost of the basketball after a 40% discount is $21.00.

Answer:

11 + 7i

Step-by-step explanation:

(1 + 2i)(5 - 3i)

= 1(5 - 3i) + 2i(5 - 3i)

= 5 - 3i + 10i - 6i^2  

Note i^2 = -1 So we have:-

5 + 7i + 6  

= 11 + 7i  (answer).

The expression (1+2i) times (5-3i) simplifies to -1 + 7i by using the distributive property for multiplication over addition and remembering that i squared equals -1.

The expression (1+2i) times (5-3i) is a function of two complex numbers. To simplify this, you would use the distributive property for multiplication over addition.

The first step is to distribute each component of the first number against each component of the second number. (1 * 5 + 2i * -3i) + (1 * -3i + 2i * 5)

Next, we perform the multiplications and simplify, bearing in mind that i squared is -1. This gives us (5 - 6) + (-3i + 10i)

So the simplified expression is -1 + 7i.

y=[tex]6x+ \frac{1}{2}[/tex]

Step-by-step explanation:

m=6

yint=1/2

y=mx+b

when x=0 y=1/2

1/2=6(0)+b

b=1/2

y=[tex]6x+ \frac{1}{2}[/tex]

The equation of the line in slope-intercept form is y = 6x + 1/2, where the slope is 6 and the y-intercept is 1/2. The slope of 6 means that for every increase of 1 in the x-axis, the y-axis will increase by 6.

The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.

Given that the slope is 6 and the y-intercept is 1/2, the equation of the line is y = 6x + 1/2.

The slope of 6 means that for every increase of 1 in the x-axis, the y-axis will increase by 6.
