25m + 100 - 24m - 75 = 68.

Maksim231197 [3]

25m+100−24m−75=68

Step 1: Simplify both sides of the equation.

25m+100−24m−75=68

25m+100+−24m+−75=68

(25m+−24m)+(100+−75)=68(Combine Like Terms)

m+25=68

Step 2: Subtract 25 from both sides.

m+25−25=68−25

m=43

Answer:

m=43

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?

Helen [10]

Answer:

$y=7x+1$

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem we have

$m=7$

$point(1,8)$

substitute and solve for b

$8=7(1)+b$

$8=7+b$

$b=8-7=1$

The equation of the line is equal to

$y=7x+1$

Help please will mark brainless 25 points due today

harkovskaia [24]

here's the solution,

we know that, sum of measures of each interior angle of a triangle = 180°

Figure 1.

=》

$40 + 32 + 9x + 9 = 180$

=》

$81 + 9x = 180$

=》

$9x = 180 - 81$

=》

$x = \frac{99}{9}$

=》

$x = 11$

Figure 2. 

=》

$42 + 63 + 4x + 15 = 180$

=》

$120 + 4x = 180$

=》

$4x = 180 - 120$

=》

$4x = 60$

=》

$x = \frac{60}{4}$

=》

$x = 15$

Figure 3.

=》

$45 + 45 + 3x - 21 = 180$

=》

$3x + 69 = 180$

=》

$3x = 180 - 69$

=》

$3x = 111$

=》

$x = \frac{111}{3}$

=》

$x = 37$

What are the zeros of the function? what are their multiplicities? f(x)=x^4-4x^3+3x^2

-Dominant- [34]

Since each term contains x, x= 0 is one answer Also as x^2 is a factor it has duplicity 2.
Factoring:-

x^2 (x^2 - 4x + 3) = 0
x^2( x - 3)(x - 1) = 0

so x = 3 and x = 1 are also zeros

Answer:- x = 0 (duplicity 2), x = 1 and x = 3.
