What is the value of the expression below -0.75-(-2/5) + 0.4 + (-3/4) help please!!

Reika [66]

-0.75-(-2/5) + 0.4 + (-3/4)

Simplify it :-)

-0.75 + $\frac{2}{5}$ + 0.4 - $\frac{3}{4}$

Add the like terms / add your decimals with your decimals & your fractions with your fractions.

(-0.75 + 0.4) + ( $\frac{2}{5}$ - $\frac{3}{4}$ )

Simplify :-)

0.35 + ( $\frac{8}{20}$ - $\frac{15}{20}$ )

Simplify :-)

0.35 + (- $\frac{7}{20}$ )

Now you turn your decimal into a fraction.

0.35 = 35/100 = 7/50

NEW PROBLEM : $\frac{7}{50} +$ + $\frac{7}{20}$ = ??

Make both denominators 100.

$\frac{7}{50}$ × $\frac{2}{2}$ = 14 / 100

7/20 × 5/5 = 35/100

NEW PROBLEM : $\frac{14}{100}$ + $\frac{35}{100}$ = $\frac{49}{100}$

Help me on 12 and 13 please

posledela

Answer:

12. h=3

13. h=-3

Step-by-step explanation:

12. Recall that $-2^{x-h}$ is a horizontal shift since h is being applied within the operation to the input. This means that h will slide the function left or right. Since the function f has a point at (1,-2) and g has the same point at (4,-2) then the function has moved 3 units 1+3=4 to the right. h=3.

13. Once again, h is a horizontal shift meaning the graphs has moved left or right only. Looking at g it has a point at (-2,2) while f has the same point at (1,2). So the graph f has moved to the left 3 units. This is h=-3 since 1+-3 = -2.

Solve for x (picture is included below)

Anna11 [10]

Solve for x:

4x - 7 = 3

Add 7 to both sides

4x = 10

Divide both sides by 4

x = 10/4

Simplify:

x = 5/2

Answer for question 1: x = 5/2

13 + 2x/3 = 15

Multiply both sides by 3

39 + 2x = 45

Subtract 39 from both sides

2x = 6

Divide both sides by 2

x = 3

Answer for question 2: x = 3

10x + 7 = 15

Subtract 7 from both sides

10x = 8

Divide both sides by 10

x = 8/10

Simplify

x = 4/5

Answer for question 3: x = 4/5

Use the quadratic formula to solve x2 + 9x + 10 = 0. What are the solutions to the equation?

vampirchik [111]

Answer:

$\large\boxed{x=\dfrac{-9\pm\sqrt{41}}{2}}$

Step-by-step explanation:

$\text{The quadratic formula of}$

$ax^2+bx+c=0$

$\text{If}\ b^2-4a0,\ \text{then the equation has two solutions}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\=========================================$

$\text{We have}\ x^2+9x+10=0\\\\a=1,\ b=9,\ c=10\\\\\text{substitute:}\\\\b^2-4ac=9^2-4(1)(10)=81-40=41>0\qquad _{\text{two solutions}}\\\\\sqrt{b^2-4ac}=\sqrt{41}\\\\x=\dfrac{-9\pm\sqrt{41}}{2(1)}=\dfrac{-9\pm\sqrt{41}}{2}$
