Help meh plz I just need answer question in pic

Yanka [14]

Answer:

Step-by-step explanation:

At the vertex, the quadratic term in this notation must be zero, i.e., the (x-1) part. This happens for x=1. So you can already rule out answers C and D.

Now fill in x=-2 in both remaining answers and see what happens.

For A: y = -2(-2 - 1)² + 3 = -15

For B: y = (-2 - 1)² + 3 = 12

That eliminates B and leaves A.

Make x the subject of these equations.

shepuryov [24]

$(1)a(x + b) = c \\ ax + ab = c \\ ax = c - ab \\ \frac{ax}{a } = \frac{c - ab}{a} \\ x = \frac{c - ab}{a}$

$(2)8(x + a) = b \\ 8x + 8a = b \\ 8x = b - 8a \\ \frac{8x}{8} = \frac{b - 8a}{8} \\ x = \frac{b - 8a}{8}$

$(3)a(x - 7) = b \\ ax - 7a = b \\ ax = b + 7a \\ \frac{ax}{a} = \frac{b + 7a}{a} \\ x = \frac{b + 7a}{a}$

$(4)c(2 + x) = 6 \\ 2c + cx = 6 \\ cx = 6 - 2c \\ \frac{cx}{c} = \frac{6 - 2c}{c} \\ x = \frac{6 - 2c}{c}$

lozanna [386]

Answer:

Part a) The straight-time pay is $\$1,332$

Part b) The overtime pay is $\$432$

Part c) The total pay is $\\$1,764$

Step-by-step explanation:

Part a) What is his straight-time pay?

To find out his straight-time pay multiply the hourly rate of $36 by 37 hours worked

$(36)(37)=\$1,332$

Part b) What is his overtime pay?

we know that

The hourly rate for overtime is equal to

$(1.5)(36)=\$54$

Multiply the hourly rate for overtime by the number of hours overtime

$(54)(8)=\$432$

Part c) What is his total pay?

we know that

The total pay is equal to sum the straight-time pay plus the overtime pay

$\$1,332+\$432=\$1,764$
