-10 + 7/4p = -38 I’m trying to figure it out but I just can’t

Step-by-step explanation:

let eqn be y = mx + b.

2x + 9y = 8

9y = -2x + 8

y = -2/9 x + 8/9

since the lines are perpendicular, product of the slope of the two lines = -1.

hence,

m x -2/9 = -1

m = 9/2

sub (0, -3):

-3 = 9/2(0) + b

b = -3

therefore equation is: y = 9/2x - 3

Answer:

4/9

Step-by-step explanation:

From the picture :

The nine chips are : 1, 2, 3, 4, 5, 6, 7, 8, 9

Even chips = 2, 4, 6, 8

Probability = number of required outcomes / (number of total possible outcomes)

Probability of drawing a chip with an even number :

P(even number) = number of even chips / total number of chips

P(even number) = 4 / 9

Answer:

6583.5 cm³

Step-by-step explanation:

[tex]\boxed{volume \: of \: hemisphere = \frac{2}{3}\pi {r}^{3} }[/tex]

[tex]\boxed{volume \: of \: cylinder = \pi {r}^{2} h}[/tex]

Thus, volume of half cylinder= ½πr²h

Since both has a radius of 10.5cm, substitute r= 10.5 into both formulas. The value of h is 24 since it is given that the height of the half cylinder is 24cm.

Volume of composite solid

[tex] = \frac{2}{3}( \frac{22}{7})(10.5^{3} ) + \frac{1}{2} ( \frac{22}{7} )( {10.5}^{2} )(24) \\ = 2425.5 + 4158 \\ = 6583.5 \: cm^{3} [/tex]

Step-by-step explanation:

Answer: 56% of people in the audience are male.

Step-by-step explanation:

Given : Total people in the audience = 143

Number of females = 63

Number males = (Total people ) - (Number of females )

= 143 -63

= 80

The percent of people in the audience are male = [tex]\dfrac{\text{Number of males}}{\text{Total people}}\times100\%[/tex]

[tex]\dfrac{80}{143}\times100\%=55.94\%\approx56\%[/tex]

Hence, 56% of people in the audience are male.

Answer:

x=1

Step-by-step explanation:

The value for x is 0 or 1.

The exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if [tex]b^x[/tex] = n

Given:

logx + log(x + 2) = log(3x)

Using the Property

log a+ log b= log(ab)

So, logx + log(x + 2) = log(3x)

log ( x(x+ 2)) = log( 3x)

Now, Comparing

x(x+2) = 3x

x² + 2x = 3x

x² = x

x²-x= 0

x(x-1)= 0

x=0 or 1.

Answer: 3107238 XD 2+2=22

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

Answer:

x = -1

Step-by-step explanation:

Start out by making the equations equal to each other since we are trying to find x (if x is the same for both equations, which it is for this problem due to the equations shown above).

18x + 26 = 2x + 10

Now that the equation is set up to find x, we need to get x by itself. Now subtract 2x on all sides to get all the x variables on the same side. Apply the same logic for the normal numbers by subtracting 26 on all sides to get the normal numbers on one side. You should end up with the numbers shown below for this step:

18x + 26 = 2x + 10

-2x   -26   -2x  -26

16x = -16

For the final step, remember that we want x by itself, so we have to divide both sides by 16 to get x by itself. After dividing both sides, you should end up with x = -1.

16x = -16

16      16

x = -1

Answer:

Distance = 4 miles

Displacement = 0

Step-by-step explanation:

Given that :

Speed of honey bee = 4mph

Total travel time = 1 hour

Distance traveled by the honey bee:

Distance traveled = speed * time

Distance traveled = 4mph * 1 hour

Distance traveled = 4 miles

Displacement = 0 miles ; change in distance from initial position.

Since initial position of the honeybee is the beehive and its final position is the beehive. Hence, the change from its initial position is zero
