Answer:

-82.8

Step-by-step explanation:

15.45 + ( − 98.25)

15.45 - 98.25

= -82.8

Since the two terms are of opposite signs, you have to subtract and use the sign of the greater term (positive or negative)

Choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8

Maru [420]

Answer:

$f(x)=8x^2+73x-70$

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

$f(x)=a(x-(-10))(x-\frac{7}{8})$

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

$f(x)=8(x-(-10))(x-\frac{7}{8})$

now, we can simplify it

$f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)$

so, we get

$f(x)=8x^2+73x-70$

Find the output for the graph y = -6x + 25 when the input value is 3. = y = [?]

avanturin [10]

Answer

$x=\frac{11}{3}$

Explanation

Based on the given conditions, formulate:: $y=3$

Substitute $y=3$ into $y=-6x+25$ :: $3=-6x+25$

Rearrange variables to the left side of the equation: $6x=25-3$

Calculate the sum or difference: $6x=22$

Divide both sides of the equation by the coefficient of variable: $x=\frac{22}{6}$

Cross out the common factor: $x=\frac{11}{3}$

90,100,120,120,140 calculate the median distance

skad [1K]

Answer: 120

Step-by-step explanation:

The median of a given set for numbers will be gotten when we arrange the numbers that are given in either ascending or descending order and then get the number in the middle.

Therefore, since we are given 90,100,120,120,140, it means that we have 5 numbers and the 3rd number will be the median distance. Thus will be: = 120
