Answers

The answer :
20 + (50) = 70
50-(-20) = 70
70 = 70

How do you answer this?

Answers

$(m^(-2))^5=m^(-2\cdot5)=m^(-10)$

$x^2+3x-10=\nx^2+5x-2x-10=\nx(x+5)-2(x+5)=\n(x-2)(x+5)$

(m*-2)*5 simplifies to m*-10.

Step-by-step explanation:

You have $1.55 worth of dimes and nickels in a jar. There are 23 coins in the jar. How many dimes do you have? How many nickels do you have

Answers

If the jar has $1.55 worth of dimes and nickels in a jar. There are 23 coins in the jar then there are 8 dimes and 15 nickels in the jar.

The total value of dimes and nickels in the jar is $1.55.

There are 23 coins in the jar.

d + n = 23 ...(1)

The total value of dimes and nickels is $1.55

0.10d + 0.05n = 1.55 ..(2)

Now, we need to solve this system of equations to find the values of "d" and "n."

We can use substitution or elimination method to solve it. Let's use the substitution method:

From Equation 1, we can rewrite it as: d = 23 - n

Now, substitute this value of "d" in Equation 2:

0.10(23 - n) + 0.05n = 1.55

2.30 - 0.10n + 0.05n = 1.55

Combine like terms:

-0.05n = 1.55 - 2.30

-0.05n = -0.75

Now, divide by -0.05:

n = -0.75 / -0.05

n = 15

Now that we have the value of "n" (nickels), we can find the value of "d" (dimes) from Equation 1:

d = 23 - n

d = 23 - 15

d = 8

Hence, there are 8 dimes and 15 nickels in the jar.

Write the slope-intercept form of the equation of the line through the given points. through: (3, -4) and (-4, 4)

Answers

first, you need your slope. this can be found by the slope formula: m = (y2 - y1)/(x2 - x1)

(3, -4) and (-4, 4)
(x1, y1) and (x2, y2)

m = (4 - -4)/(-4 - 3)
m = (8)/(-7)
so your slope is -8/7

now, to find a line through the given points, the only piece of information you're missing is your y-intercept. you just have to pick one point and plug it into slope-intercept form: y = mx + b, then solve for b

(-4) = (-8/7)(3) + b
-4 = -24/7 + b
-4/7 = b

so plug all of it into y = mx + b:

y = (-8/7)x - 4/7
