Which equations can be used to find the value of x? 4x - 90 = 180 2x + 90 = 180 4x + 90 = 180 2xº 2x + 2x + 90 = 180 2xº 2x + 90 = 360 4x = 90 Two equations are shown. y = 3x y = x - 3 Which statements about the relationships between x and y are TRUE? Select all the correct answers. In y = 3x, the value of y is 3 times the value of x. In y = 3x, the value of y is 3 greater than the value of x. In y = 3x, the value of x is 3 less than the value of y. In y = x - 3, the value of y is 3 times the value of x. In y = x - 3, the value of x is 3 greater than the value of y. In y = x - 3, the value of x is 3 less than the value of y. Match each term to the correct description. Operation that maps a geometric figure onto a new figure Transformation ? Enlarges or reduces a figure by a scale factor Dilation ? Resulting figure after a transformation Image ? Original figure before a transformation Preimage ? "Flips" a figure over a line such as the x- or y-axis Reflection ? "Slides" a figure without turning it Translation ? When a figure is turned around a fixed point Rotation ? Match each slope to the graph it describes. Undefined Slope ? Positive Slope ? Negative Slope ? Zero Slope ? Given: (-3)2 + 6(1 - 3) ÷ 3 - 11 Drag and order this student's work to show the correct steps to simplify the expression. Drag the incorrect step to the "Not Used" pile. (-3)2 + 6(-2) ÷ 3 - 11 ? 9 - 12 ÷ 3 - 11 ? 9 - 4 - 11 ? 5 - 11 ? -6 ? -9 - 12 ÷ 3 - 11 ? Not Used G E M S Step 1: Step 2: Step 3: Gus is solving the given equation for y. Order the steps Gus will likely take to solve for y. Subtract both sides of the equation by 1 ? Multiply both sides of the equation by 2 ? Divide both sides of the equation by 3 ? 1 solution ? 4x + y = 7 y - x = 5 Three systems of equations are shown. Indicate the number of solutions for each system. No solution ? y = 3x + 7 y = 3x - 2 Infinitely many solutions ? 2x + 5y = 12 8x + 20y = 48 Find the GCF of 15n4p3 and 20n2p5.
