What is the result of adding these two equations?
4x-4y=-2
-9x-4y=-3

Answer:

(1.5×5) + (2.5×4)

Step-by-step explanation:

if 1.5 + 2.5 is 4.0, and you have $18 and you would see how many times 4 can go into 18 (18÷4) which has four times then you have $2 left so you can get another lip balm so x equals 5 and Y equals 4. I hope this helps! :D

Answer:

false

Step-by-step explanation:

Answer:

False, it has no solution if the lines are parallel.

Answer: 64 ; $28

Step-by-step explanation:

A. Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left?

Number of conks collected by Billy = 256

Fraction lost = 3/4

Amount lost = 3/4 × 256 = 192

Number of conks Billy has left will be:

= 256 - 192

= 64

B. Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?

This will cost:

= 7/9 × $36

= 7 × $4

= $28

Carmen has the largest red to green apple ratio.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

here, we have,

from the given chart , we get,

the  ratio as,

Carmen= 20:12

            =1.6

Dylan = 12:10

          =1.2

Eli = 16:20

    =0.8

now, we have,

Carmen has the largest red to green apple ratio.

This is because his red to green apple ratio is equal to 1.6.

In order to determine that you take 20 and divide it by 12.

Answer:

y=2x-2

Step-by-step explanation:

my work is in the picture I attached. lmk if you'd like me to explain more

Answer:

y = 2x - 2

Step-by-step explanation:

let equation of the line be y = mx + c

since it is parallel to y = 2x + 2, gradient/slope of the two lines would be the same

therefore, m = 2

since it passes through (4, 6),

sub (4, 6):

6 = 2(4) + c

c = -2

therefore equation of the line is y = 2x - 2

Answer:

[tex]y-6=-6(x-1)[/tex]

Step-by-step explanation:

A point-slope equation requires two values in order to write it: one coordinate and the slope.

First, find the slope between the two given points. To find the slope, you would subtract the first Y from the second Y and the first X from the second X. Y goes on top of the fraction bar, making the equation look like this:

[tex]\frac{6-(-6)}{1-3}[/tex]

Then, simplify the slope equation:

[tex]\frac{6-(-6)}{1-3} = \frac{6+6}{1-3} = \frac{12}{-2} = -6[/tex]

The slope is -6.

Finally, choose one of the coordinates. For this, I'll pick (1, 6).

The point-slope equation is [tex]y-y_{1} =m(x-x_{1})[/tex]

So, simply fill in the [tex]m[/tex], [tex]y_{1}[/tex] , and [tex]x_{1}[/tex] spots with the value we have found.

[tex]m[/tex] is the slope, so replace it with -6.

[tex]y_{1}[/tex] = 6

[tex]x_{1}[/tex] = 1

Final answer:

[tex]y-6=-6(x-1)[/tex]

Answer:

2.12 seconds

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 15t + 40[/tex]

Required

Determine how long the ball hits the ground

When the ball hits the ground means that [tex]h(t) = 0[/tex]

So, we have that:

[tex]h(t) = -16t^2 + 15t + 40[/tex] becomes

[tex]0 = -16t^2 + 15t + 40[/tex]

Reorder

[tex]-16t^2 + 15t + 40 = 0[/tex]

Multiply through by -1

[tex]16t^2 - 15t - 40 = 0[/tex]

Solve using quadratic:

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 16[/tex] [tex]b = -15[/tex] [tex]c = -40[/tex]

So, we have:

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex] becomes

[tex]t = \frac{-(-15)\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]

[tex]t = \frac{15\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]

[tex]t = \frac{15\±\sqrt{225 +2560}}{32}[/tex]

[tex]t = \frac{15\±\sqrt{2785}}{32}[/tex]

[tex]t = \frac{15\±52.77}{32}[/tex]

Split:

[tex]t = \frac{15+52.77}{32}[/tex] or [tex]t = \frac{15-52.77}{32}[/tex]

[tex]t = \frac{67.77}{32}[/tex] or [tex]t = \frac{-37.77}{32}[/tex]

[tex]t = 2.12[/tex] or [tex]t = -1.18[/tex]

But time can't be negative

So:

[tex]t = 2.12[/tex]

Hence, time to hit the ground is 2.12 seconds

Answer:

Step-by-step explanation:

I = prt

I = 800 × 1.8% x 15

I = $216

Remember the percent sign for the rate or write it as a decimal (multiplier)! In this case the multiplier would be 0.018!

Amount of cherries left:

Answer:

Step-by-step explanation:

are there options

Answer:

-9

Step-by-step explanation:

x + 109 + x + 89 = 180° because these angles are supplementary

2x + 198 = 180 subtract 198 from both sides

2x = - 18 divide by 2

x = -9

Answer:

1/4 equal pieces

Step-by-step explanation:

Total number of bowls of rice = 3

We are seeking servings of size 12

Then it means we are dividing 3bowls into 12 equal pieces

= 3/12 bowls

= 1/4 equal pieces

Which means each member of the family is getting 1/4 each of the bowl of rice

Therefore, 1/4 servings of size 12 can you make out of the 3 bowls of rice

A) Assoicative Property of multiplication

Step-by-step explanation:

For associative prop., the order stay the same but the () move.

Slope formula - y = mx + b

6x + 2y = 10

subtract x

2y = 10 - 6x

divide all by 2

y = 5 - 3x

y = -3x + 5

5 is the y-intercept, and -3x is the slope

Answer:

The three integers are

11, 13, and 15.

Step-by-step explanation:

. The sum of these is 39, so we can write:

x+(x+2)+(x+4)=39

Open the brackets and simplify.

x+x+2+x=+4=39

3x+6=39

Subtract 6 from each side.

3x=33

Divide both sides by 3.

x=11

Therefore: (x+2)=13 and (x+4)=15

Answer:

for the second question , all you have to do is substitute , the first point plotted is x and the second point is b , ploy those points in the equation and remember that to find x we make y= 0 and to find y we make x =0
